Econ 101: The Value of Money

During a discussion of Bitcoin with friends, it became clear to me that it might be helpful if I explained some fundamentals of how the value of money is determined. Like most everything else, money’s value is ultimately determined by its supply and demand.

Demand for money reflects the public’s need to keep an inventory of it in order to use it for making payments.  Bitcoin are generally held as a speculative asset rather than for payments as almost no one will accept them in payment. “Cryptocurrencies-the bitcoin phenomena”

The supply of money is determined by those who created it, generally central banks. Generally central banks issue their currency, thus increasing its supply, by lending it (generally to banks) or by buying assets, generally their government’s debt.  When anyone holding that currency no longer wants it and has the right to redeem it, the central bank takes it back in exchange for the asset it purchased in the first place, thus reducing the money supply.  Under the gold standard, currency was redeemed for gold.  The rules governing a central bank’s issuing and redeeming its currency defines the nature of its monetary regime.  That is the topic of this econ 101 lesson.

As none of us has ever redeemed our currency, it is understandable that my friends confused spending their money with redeeming it.  Spending it transfers it to someone else without changing its supply, while redeeming it reduces its supply.  Cryptocurrencies add a new category to our discussion of money.  As noted by “a billionaire hedge-fund manager… cryptocurrencies are a ‘limited supply of nothing.’”  “Crypto skeptics growing”

As discussed further below, the supply of Bitcoin increases slowly and steadily over time as determined by an unchangeable formula and Bitcoin cannot be redeemed for anything.  The U.S. dollar and virtually every other national currency in the world grow at more erratic rates as determined by their issuing central banks.  So what makes the value of the dollar relatively stable over long periods of time?  The fall in its value by about 8% over the last month is nothing compared to bitcoin’s fall of 23% over the same period and over 50% over the last half year.  Over the past 15 years the dollar’s value has declined less than 2% each year.  Unlike Bitcoin, dollars are widely accepted for payments that are denominated in dollars, including our taxes, and thus held (demanded) to make such payments.  Almost no Bitcoins are held to make payments as almost no one will accept them for payments.  But I want to focus on a currency’s supply.

There are fundamentally three broad approaches to determining the supply of a currency.  Historically, the supply of most currencies were determined by fixing their price to what they could be redeemed for, such as gold or silver. I have called such a system for regulating money’s supply, a hard anchor. “Real SDR Currency Board”  The value of a currency can be fixed (the price set) to something real such as gold or a basket of goods.  A country with a strict gold standard, which the U.S. never really had, issues its currency (dollars) whenever anyone wants to pay the fixed gold price for more of them.  If the dollar price of gold in the market rises above its official price, there would be an arbitrage profit from buying gold from the central bank at its lower official price.  Such gold could be resold in the market at the higher price.  But the key point is that this mechanism (what I call currency board rules) of redeeming currency reduces its supply and thus reduces prices in this currency in the market (deflation).  Several of the monetary systems I helped establish, work in this way (Bulgaria and Bosnia and Herzegovina). “One Currency for Bosnia”

The most common system of monetary control today is for the central bank to determine its currency’s supply by buying or selling it in the market (the Federal Reserve can buy treasury bills, etc. to increase the supply of dollars).  Most central banks today adjust their money supplies in an effort to achieve an inflation target (a much more complicated subject). “Czech National Bank: Inflation Targeting in Transition Economies”  Generally they do so by setting an intermediate target for a short-term interest at which market participants (banks) can borrow from the central bank.  Such fiat currencies, such as the U.S. dollar, are not redeemable but are widely accepted in payment for goods, services and debts.

This brings us to Bitcoin.  The supply of Bitcoin is determined by a formula that predetermines its gradual growth to 21 million by 2140.  There are currently about 19 million in existence.  The supply is increased by giving them to successful miners for verifying the legitimacy of each transaction (another complicated subject).  Thus, the issuer (the formula) received services (protection against double spending the same coin) but no assets such as gold or treasury bills for creating and issuing new Bitcoins.  Once created, an issued bitcoin can never be redeemed (i.e. the outstanding supply can never be reduced).  When you spend or give away your Bitcoins you are circulating them to other holders, not redeeming them.

When my imaginary aunt Sally discusses Bitcoin and cryptocurrencies more generally, she tends to mix up the marvelous new payment technologies for paying my dollars all over the world with private money such as Bitcoin and Tether.  She also doesn’t seem to quite understand that most money has always been privately produced including the U.S. dollars that we spend in various ways (occasionally even by handing over cash).  “A shift in monetary regimes”

But these distinctions are critical when considering what role the government should play in our monetary system.  The truly amazing technical progress we have experienced and the dramatic increase in the standard of living of the average person it has delivered over the last century was made possible by a government that provided a general framework in which we, the consuming beneficiaries of this progress, could make informed choices.  Our government, wisely, generally did not make such decisions for use.

With that in mind consider “a letter addressed to Senate Majority Leader Charles E. Schumer (D-N.Y.), Senate Minority Leader Mitch McConnell (R-Ky.), House Speaker Nancy Pelosi (D-Calif.) and other congressional leaders, [from 26 influential technology personalities that] outlined what it described as potentially grave dangers of cryptocurrencies.” They are absolutely correct to expose and condemn the technical and economic weaknesses of blockchain technology—the distributed ledger with which Bitcoin claims to avoid the need for trusted third parties to record and document payment transaction (as happens on a centralized ledger when you pay from your bank deposit). 

But the fact that foolish people invest in Bitcoin and other cryptocurrencies does not justify our government prohibiting and restricting them from doing so.  The government requires the banks in which we put our money to publish properly audited financial statements of the assets backing our deposits and to set minimum capital requirements to protect against the possible loss of bank asset value (e.g., loan defaults).  Cryptocurrencies claiming redeemability at a stable value (so called stable coins) should similarly be required to disclose the rules by which they operate and the composition and value of the assets backing their digital coins.  In short, government regulations should help us decide what we want to buy and/or hold without restricting the ability of fintech pioneers to explore and innovate products to offer.

Overly restrictive regulations create incentives for incumbents to create barriers to competition.  Large and intrusive governments tend toward corruption.  The Federal Reserve System seems quite aware of these risks as it cautiously explores whether to compete with the private sector in developing a central bank digital currency.  “Econ 101-Central  Bank digital currency-CBDC”

So when considering the government’s role in money and payments be sure to clearly distinguish money from payment technology and limit government to setting the rules of the game that maximize the ability of private consumers to make wise choices. But perhaps the biggest policy decision of all is how the government should determine/regulate the supply of its currency, most of which is privately created.  I support a currency whose value is fixed to something real (a hard anchor) and whose supply is determined by the market via currency board rules.  “A libertarian money”  

Econ 101: Retail Central Bank Digital Currency (CBDC)

The history of money is long and fascinating. Even the currency most frequently used in the United States has a rich history. Money makes possible the specialization and trade upon which our great wealth depends. Through its long history of development and evolution, money has serviced two key functions. It provides the standard unit for pricing traded goods and services so that their values can be meaningfully compared (it’s the unit of account) and it is the common asset in which payments are made (it’s the medium of exchange or payment).

Medium of Payment–Money

When you hire the neighborhood boy to mow your lawn, you probably first agree on a price (the number of dollars) This is the unit of account function of money, which is indispensable for the functioning of markets.  You could agree to trade with the neighborhood boy a nice lunch with lemonade in exchange for his mowing your lawn. But paying him $15 in Federal Reserve Notes has the advantage that he can exchange it for your lunch, or he can buy his lunch at Wendy’s or anything else of his choice.

Obviously, markets can’t really function if each item or service is priced in a different money unit (dollars, Euro, rubles, bitcoin, etc.). The Continental Congress of the United States authorized the issuance of a new currency, the US dollar, on July 6, 1785. Following the ratification of the Constitution of the United States, the new Congress established the United States dollar as the official currency of the United States in the Coinage Act of 1792. The Act also established the United States Mint, which produced and circulated coins with a fix amount of gold or silver (later only gold). “History of the United States dollar”  

As the result of the changing relative price of silver for gold, the bimetal gold/silver standard was replaced with the single metal standard of gold. The dollar was redefined in 1900 as “twenty-five and eight-tenths grains of gold nine-tenths fine,… and all forms of money issued or coined by the United States shall be maintained at a parity of value with this standard.” Fast forwarding through WWI and WWII and the creation of the Bretton Woods Institutions and the failure of the US to adhere to the requirements of the gold standard, the US “closed its gold window” and proceeded with varying degrees of success to manage the supply of its currency so as to preserve its purchasing power.

Over this long history many private actors (banks) created dollars. There are in fact thousands of private producers of dollars (Chase dollars, B of A dollars, etc.) Glossing over the details, it was a one currency system–the US dollar–because each bank’s currency could be redeemed for gold at  fix price or, after the creation of our central bank in 1913, for a deposit at a Federal Reserve Bank. This is obvious when you pay with Federal Reserve Notes, which are direct obligations of our central bank. Originally each note was identified by the Federal Reserve Bank that issued it–there were twelve of them–but even that distinction has been eliminated. Few people even noticed the difference. But most of our dollar money supply (M1: Federal Reserve Notes in circulation plus demand deposits at banks) is privately produced by banks and exists in digital form as accounting records with each of our banks.

Means of Payment

Our money–US dollars (or Euros or bitcoin)–is quite distinct from the various ways in which you can pay it–payment technologies. Cash payments–the transfer of Federal Reserve Notes from me to you–are hand delivered. But most payments are made by digitally transferring an amount of dollars from my bank account to yours. Such digital payments have the obvious advantage of enabling you to pay someone across town, across the country or even across the world (if they accept your currency) plus the safety of keeping your money in the bank pending such payments.  It’s not recommended that you send cash in the mail. The key insight is to understand how my dollar balance in my bank gets to your account at your bank and why your bank is willing to accept it. The quick answer is that your bank will not generally accept a claim on my bank but will record my payment because it receives an increase in its deposits at a Federal Reserve Bank of that amount.

In the old days I wrote a check that authorized my bank (after the check was deposited by you at your bank, which sent it to my bank) to debit my balance with the indicated amount and to transfer that amount from its balance at the Fed to your bank’s account at the Fed. SWIFT performs this payment instruction/authorization function for cross border payments (i.e., those involving two central banks). Today I issue this instruction directly to my bank electronically on the internet or my smart phone. The “dollars” are one currency no matter who creates and issues them because whoever receives them can redeem them for balances at the central bank (or in the old days for gold).

Visa, Master Card and American Express credit cards provide payments on my behalf by lending me the money before I actually make the payment from my bank account to the credit provider at the end of the month. The loan to me involved in such payments, increases the cost of this type of payment.

The execution of the interbank portion of my payments have become increasingly efficient over time but can still take several days because the Federal Reserve Banks do not operate in the evening or on weekends. When our central bank launches FedNow next year it will allow the continuous processing of payments between banks 24/7.

The front end of the payment process, i.e., my initiation of a payment to you, for example, has also benefited from software improvements. Unlike bitcoin, Ethereum, or Ripple, which are currencies, Zelle, Venmo, PayPal, etc. are payment technologies rather than money. They are means for paying US dollars (or other currencies) from me to you. Venmo, for example can be thought of as the payment service part of a bank. It can hold money for you and can transfer it to others (who must also have a Venmo account) but Venmo cannot make loans with your money. Thus, people without bank accounts can use Venmo as if it were a bank account.

The Federal Reserve and other central banks are investigating whether they should also provide the service to the public of paying dollars with so called Central Bank Digital Currency (CBDC). The Federal Reserve defines a CBDC “as a digital liability of the Federal Reserve that is widely available to the general public.” “Money and payments–Fed report”  CBDCs would be a direct claim on the central bank like Federal Reserve notes (cash) but would be held and transferred digitally like your bank deposits. If the Fed goes forward with introducing CBDCs, they would almost certainly be what are called retail CBDCs. Rather than opening accounts at the Fed directly, we would each do so through a bank. We would sign up with and deal with a bank to hold the Fed’s CBDCs. The Fed has no existing capacity to deal directly with each of us in the way that our banks do. The balance of this note will explore how such CBDC would compare with, say, Venmo balances and payments and whether they are worth the trouble.

All digital money is recorded on electronic ledgers, either distributed as with a block chain used by bitcoin, or centrally maintained as with our bank accounts. As block chains are slow and expensive to verify, they would not be used for CBDCs. Just in case you didn’t know, when you walk into your bank and deposit cash, they don’t put it in the value for you. They record the value of the cash you delivered in our account with the bank, and they return the cash to the Fed for a credit to your bank’s Fed account or invest or lend it to someone else (after having converted it into a balance in their Fed account). It is both useful and interesting (to us economists at least) to walk through how my deposit at my bank is transferred to you (your account at your bank).

Taking Venmo as the example of existing digital payment technology, your deposit of dollars to your Venmo account would be digitally transferred from your bank account to your account on Venmo’s ledger. Your bank would transfer the same amount to Venmo’s deposit account with its bank (in the name of PayPal, which owns Venmo) in the usual interbank transfer manner. All (double entry) financial ledgers have a liability side (your deposit with the bank — what the bank owes you) and an asset side (the cash you deposited or the balance in your bank’s fed account for the money you had transferred to it). The ledger shows what the bank owes (liabilities) and the assets it holds with which to pay out what it owes (assets).

All digital money, whether your bank deposit or Venmo or bitcoin, must provide for an on ramp into and off ramp out of the digital system, i.e., for the process of paying cash in to acquire the digital money and of drawing it out as cash. Interestingly, Kenya has had a version of Venmo payments for several decades already. Kenya’s M-Pesa The ownership and use of cell phones (not necessarily smart phones) is very widespread in Kenya, while bank accounts are far more limited. Thus, people paid for phone airtime by the hour by paying cash to street venders selling such service. This became the on ramp for the unbanked to fund their M-Pesa mobile money accounts.

If you have money in your Venmo account (a positive balance), you can issue a payment instruction via your Venmo wallet directly to the friend you are paying. You can also instruct Venmo to take that the money simultaneously from your bank account. You can do all of this on your smart phone while waiting for your drink at a local bar. If your friend doesn’t have a Venmo account, Venmo will instruct her on how to set up one in order to receive your payment. If you give Venmo a day or two to complete the payment, it is free. If you want it delivered immediately (within a few minutes) there is a small fee. When the payment is complete, your balance at Venmo (or your bank) will have been reduced by the amount of the payment and your friend’s balance with Venmo will have been increased by the same amount. She can leave the money there or move it to her bank account (on her cell phone) if she has one. The money will “exist” as an accounting record somewhere. These “dollars” are accepted from wherever they come (from whoever produced them) because they are claims on, or are converted into deposits at, a Federal Reserve Bank.

How would this compare with a payment with central bank digital currency (CBDC)? While the Federal Reserve has not indicated the details of a possible CBDC, it would probably work something like this. I would ask my bank to sell me CBDCs by debiting my checking account by the indicated amount. These would be added to (credited to) my CBDC account at my bank.  My bank would transfer that amount from its general account at its Federal Reserve Bank to a segregated CBDC account at the Fed. My cell phone wallet would record (by accessing my CBDC account at my bank) this amount, and my bank would back it 100% with its CBDC account at the Fed.

Why does this matter? It matters because if my bank fails (goes into bankruptcy), the amount in the bank’s CBDC reserves at the Fed would be excluded from the bankruptcy process. They are exclusively and fully available to back my CBDC holdings. When I pay CBDC to my friend, her bank will receive them without regard for the condition of my bank.

Some of you will recognize this as the equivalent of the so-called Chicago Plan. The Chicago Plan required banks to back all checking account deposits 100% with central bank reserves. Our bank deposits today are largely backed by bank loans and investments plus a small deposit with the central bank. Such CBDC deposits would be totally free of default risk. While all CBDCs would exist on the books of the Federal Reserve, ownership by individuals would be reflected on the books of their respective banks and in their CBDC wallets.

Like the Chicago Plan, CBDCs have the potential to reduce the money multiplier (the ratio of broad money to base money–the Federal Reserve’s monetary liabilities). A shift from demand deposits to CBDC deposits at banks would reduce the funds available to banks for lending by increasing the reserves they must hold at the Fed. This could be easily compensated for by increasing base money (Federal Reserve monetary liabilities). Sudden shifts to the safer CBDCs in reaction to financial shocks, like traditional bank runs, would require central bank intervention. The Fed has also indicated that it would want any digital replacement of its currency notes to provide as much user privacy as possible (like cash) consistent with “affording the transparency necessary to deter criminal activity.”

How would this compare with a Venmo payment. From our perspective (the perspective of the payer and payee) a Venmo or CBDC payment would be executed in the same or very similar way. The difference is that the CBDC balances would be totally risk free (being relatively direct claims on the central bank) while the Venmo balances would be exposed to the risk of the failure of the bank in which Venmo keeps its assets that back our Venmo balances. It is not obvious that this is a big enough difference to make it worth undertaking.

Econ 101: Moving money abroad

The Washington Post published an article this morning titled “THREE DOZEN TYCOONS MET PUTIN ON INVASION DAY. MOST HAD MOVED MONEY ABROAD.“Offshore Putin Russia Oligarchs Pandora” It said things like “many of them had been moving their wealth out of the country for years,” and “The money often ends up offshore.” While where income is claimed is important for tax purposes, which is another interesting and complicated story, the abandon with which this story discusses moving wealth around drives us economists up the wall.

Wealth can be physical (factories, stores, etc.) or human (the knowledge or skills of people).  Financial wealth, such as money, is a claim on physical or human wealth. People can move abroad, and many skilled Russian’s are doing so. Moving physical capital abroad is more difficult if even possible. A yacht built in Russia can be sailed off to another country, but not a shopping mall. What this and similar articles generally mean by moving wealth abroad, is, as the headline states, moving money abroad. This is often done to minimize taxation, which is usually based on where income is recorded. “The corporate income tax” That is an interesting subject of its own but not my focus today.

How do people “move money abroad?” Money is rarely moved in suitcases anymore, and a bag full of rubles can’t be spent abroad in most places anyway.  So, let’s take a deeper look at what is really happening when Russian tycoons (or anyone else) “move money abroad.”

The easiest example is when Russian exporters are paid in foreign currency (generally US dollars). If the exporter has a dollar account in a bank abroad (in a US bank to keep it simple) the payment for his export can be deposited directly there by a debit to Shell Oil’s bank account and a credit to the Russian exporter’s US bank account via the normal interbank transfer process. He can hold it there or buy US treasures or other US financial assets. His money is moved abroad by moving (selling) his goods abroad and keeping the payment abroad. This helps explain why Russia is insisting that German and other buyers of its oil must pay in rubles.

To pay for oil or any other Russian export with rubles the foreign buyers must first buy rubles in the foreign exchange market. The increased demand for rubles increases its exchange rate (or keeps it from falling as Russian importers sell rubles for dollars to pay for imports). Russia has made the process of paying dollars then buying rubles simple and almost automatic, but critically the Russian exporter receives ruble. Normally Russian exporters would convert dollar payments into ruble with which to pay for their workers and local suppliers, etc. But by keeping the dollar payment abroad, they have effectively “moved money abroad” by shipping goods (and services) abroad.

If a tycoon’s income/wealth is local (in rubles), and he wants to move it abroad, he can’t just write a check (or SWIFT payment order) to deposit X amount of money in his account with the Bank of America. The funds in his local bank, which will be in rubles, will need to be exchanged for dollars in the foreign exchange market. He (his bank) will deposit his ruble in the ruble account of the seller of the dollars and will receive those dollars in his Bank of America account in the U.S. If the supply of dollars to the foreign exchange market are not being supplied as the result of Russian exports, the increased demand for dollars will depreciate the ruble (increase the ruble price of a dollar). With a balance of imports and exports the ruble/dollar exchange rate should be stable. But a net increase in the movement of money abroad would depreciate the ruble. In short, underlying the movement of money abroad, there is a net movement of goods (exports minus imports) abroad.

If there was a sudden increase in money being moved abroad from Russia (often called capital flight) the ruble’s exchange rate would depreciate and the cost of imports would thereby increase.

A Libertarian Money

Some people claim that libertarians like cryptocurrencies like bitcoin because they do not rely in any way on government. Perhaps those people meant “anarchists” because libertarians (to be safe perhaps I should just refer to my own views though I know that they are widely shared by other libertarians) accept the critical importance of government in defining and protecting property rights and personal safety. Bitcoin and most other cryptocurrencies do not satisfy the requirements for a good libertarian money because they do not satisfy the requirements for good money. This note explains why this is so and defines what is good libertarian money.

Are Cryptocurrencies the Answer?

Economists note the incredible power of markets and market prices in directing our scarce resources (our labor, capital, and technology) to their best uses. But prices are expressed in terms of money. The presumption, and actual reality, is that within each market prices are expressed in terms of the same money. It would not facilitate our choices if apples were priced at $6 per bushel and oranges at 3 bitcoin per bag. Presently, virtually nothing is priced in bitcoin. In addition, sellers don’t generally accept payment in a currency other than the one in which the good’s price is expressed, thus very few sellers will accept bitcoin in payment. Moreover, you can only accept bitcoin in payment if you have a bitcoin account together with the software required (a bitcoin wallet).

None of these are insurmountable barriers to growth in the use of bitcoins, but they do require strong incentives for putting up with and/or overcoming them. I explained the basics of bitcoins value in the following blog in 2014: “Cryptocurrencies-the bitcoin phenomena”   One incentive would be to replace the established currency in a market (a country’s legal tender) that has very unstable value (think Venezuela, Argentina, Brazil at various times in their histories). Another would be the need for anonymity (as is achieved with paper currency) that an illegal drug dealer or a political dissident in a repressive regime might require and find convenient.

Bitcoin’s claim to eliminate the trusted third party (bank accounting systems) required by existing electronic (digital) payments with bank deposits, is particularly attractive to libertarians.  But this claim is a gross exaggeration. To prevent the double spending of the same bitcoin, each transaction must be verified by so called miners (third parties you don’t need to trust) which takes five to ten minutes and very large amounts of electricity to process as miners race to solve increasingly difficult mathematical puzzles. Also, all transactions are very public on block chains, though accounts may be held under pseudonyms and are thus described as pseudo-anonymous.

Though actual bitcoin transactions have been made easier via the development of software wallets, many assign their bitcoins to exchanges (trusted third parties).  “The future of bitcoin exchanges”  The loss of a bitcoin owner’s password to his account is fatal and final. Those bitcoins are lost forever. But more deadly to the use of bitcoin as money (unit of account and medium of payment) is the volatility of its value.  The price of a bitcoin has ranged from just under $30,000 to over $67,500 over the last year. It is currently $39,268. Thus, payments of bitcoin generally involve temporarily purchasing them with dollars or some other stable currency and then exchanging them back to dollars as quickly as possible after receipt. The costs of these exchanges are often overlooked when claiming that bitcoin transfers are cheaper than traditional means of electronic payments. Most buyers and sellers of bitcoin are indulging in a form of gambling.

The Libertarian Alternative

There are monetary regimes, however, that satisfy libertarian preferences for minimal government involvement and manipulation. The Constitution of the United States provides the authority for such a regime in Article I Section 8 “To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures;” The classical gold standard was such a system. However, its “rules” were diluted when taken over by central banks. Moreover, the practice of actually buying and storing gold distorted its market price and was costly, flaws that are avoided in the system I propose below.

In the U.S. today, as well as every other country in the world, there are thousands of private companies that create and offer their own currency. Most of them are banks. While that would seem to make libertarians happy, thousands of individual bank producers of money would not constitute an efficient monetary system without rules and mechanisms for linking them into what we think of as one currency–in our case the U.S. dollar.

While the dollars deposited in my bank are my bank’s liability, I am protected from the bank’s failure by deposit insurance. Your bank accepts my deposits in my bank because my bank credits your bank’s account with the Federal Reserve (by debiting its account with the Fed). In short, the deposits at thousands of different banks are accepted by every other bank because they are all ultimately claims on the Fed. This is similar to the gold standard in which the money created by thousands of banks were accepted everywhere because they were redeemable for a well-defined amount of gold.

Libertarians want a currency and monetary system that can’t be manipulated by the government (central bank).  The dollar is now a fiat currency (redeemable for nothing–except a claim on, i.e., deposit with, the Federal Reserve). Thus, its supply is determined by the Fed’s judgement of what is needed for “price stability and maximum sustainable employment.” We libertarians want a currency that we each individually control the supply of. In short, we want a currency with a hard anchor (which was the case for the gold standard) supplied according to currency board  rules (which historically were violated by central banks nominally anchored by gold). Currency board rules require the currency issuer to sell or repurchase its currency at its fixed price in response to public demand. Any number of private producers of dollars redeemable at an officially fixed price for a well-defined anchor (gold, aluminum, a basket of goods, etc.) would result in a money supply determined by the public that was consistent with and appropriate for its fixed price to the anchor and that was fully interchangeable. The central bank would be passive. It would have no monetary policy (beyond the fixed price for the anchor). This seems like libertarian heaven.

I led the IMF teams that established the Central Bank of Bosnia and Herzegovina, which follows currency board rules. I have written a book about that experience:   “One Currency for Bosnia-Creating the Central Bank of Bosnia and Herzegovina”   or  “Amazon– One Currency for Bosnia” I also participated in Bulgaria’s adoption of currency board rules. The currencies of both countries are anchored to the Euro and their currency experiences have been outstanding. Their money supplies are basically regulated by market arbitrage. If the market exchange rate of the Bulgarian lev to the Euro rises above its official rate, it would be cheaper for the banks that issue lev to buy Euros from the Bulgarian National Bank thus reducing the supply of lev in the market and lowering its market price for Euro. See my blog on Bulgaria’s experience: “Bulgaria and the Chicago Plan

A Libertarian International Reserve Currency

What about cross border payments? In brief, cross border transactors have found it economical to price and settle transactions in a vehicle currency, usually the US dollar. The increasingly frequent deployment of sanctions enforced by restricting the use of the dollar has intensified the search for alternatives. See my more detailed discussion: “The Empire and the Dollar”  The search for alternatives to the dollar risks fragmenting the global market place as proposed by Russia’s Sergey Glazyev.  “A new global financial system”

The International Monetary Fund has already created such an alternative. An internationally established unit (anchor) is much less likely to be abused for national political purposes, but the IMF’s Special Drawing Right (SDR) suffers from some serious defects. However, these can be fixed. “Time for a New Global Currency”   Why the World needs a new Reserve Asset with a Hard Anchor

The SDR can be “fixed” in two stages. The first is to develop the private sector’s uses of the SDR unit of account (invoicing oil and other globally traded commodities in SDRs, borrowing and lending denominated in SDRs, SDR bonds and bills, and digital SDR deposits–eSDRs). See my more detailed discussion:  “Promoting Market SDRs”  As with national currencies, where hundreds of individual producers of the national currency are made interchangeable by being claims on the central bank, the market SDRs of many competitive producers would be interchangeable as the result of being redeemable for the official SDR of the IMF.

The second stage would require a reform of the IMF’s official SDR. Rather than allocating them from time to time to all IMF members, they should be issued according to currency board rules. In addition, the valuation of the official SDR should be changed from its current basket of five currencies to a small basket of homogeneous, globally traded commodities. The IMF’s existing rules for periodically adjusting the SDR’s valuation basket are transparent and appropriate and should continue to be used. In one sense, this would reestablish an improved international gold standard like system. It would be improved by replacing a single commodity anchor with a small portfolio of commodities and its supply would be improved by adopting the market driven rules of a currency board.  “Free Banking in a Digital Age”

The Empire and the Dollar

Committee for the Republic Salon

March 24, 2022

Warren Coats[1]

In our multicurrency world, the U.S. dollar is widely used for pricing internationally traded goods, for international payments, and for denominating the assets governments and companies hold as reserves. Why is that and what are its implications for U.S. behavior? What would a better system look like?

In a world of many different national currencies, the payment for international trade has found economy in using an intermediate, so-called vehicle currency to facilitate the exchange of the buyer’s currency into and delivery of the seller’s currency. Following the collapse in 1971 of the dollar-based gold exchange standard overseen by the International Monetary Fund, the dollar continues to dominate in this role. This role has given the United States important political power and financial benefits.

I will quickly review these benefits, and how they have come to encourage the U.S. to exploit them in exercising its international power, the forces that are building to seek an alternative, and the potential for the IMF’s Special Drawing Rights (SDRs) to provide an alternative.

The Dollar’s International Reserve Status

Cross border commerce and investments require a common currency to price and denominate them and the mechanisms for cross border payments. While modern technologies continue to increase the speed and ease and lower the cost of domestic payments of domestic currencies, cross border payments remain relatively slow and costly.

The payment and receipt of a currency is ultimately reflected/settled on the books of that currency’s issuer. If I pay you for something and your account is in a different bank than mine, the transfer of funds from my bank to your bank and to you will pass through a Federal Reserve Bank. My bank’s account at the Fed will be debited and yours will be credited.  A fundamental difference between national and international currencies is that the central bank issuers of national currencies only hold deposits for banks that are domestically licensed, while the issuers of international currencies, such as the Special Drawing Right (SDR) of the International Monetary Fund, hold deposits from banks almost anywhere in the world, enabling the settlement of their payments to enjoy the efficiencies of domestic payments in domestic currencies.

The older gold standard functioned more like an international central bank issuer of currencies but without such an international central bank. Instead, national currencies were tied to gold by virtue of the commitment of central banks on the gold standard to redeem their currency for gold at a fixed price. Thus, any net flow of payments from one country to another was ultimately settled by transferring the ownership of the gold it was fixed to from the deficit to the surplus country. This could occur by debiting the deficit country’s gold account at the New York Federal Reserve Bank and crediting the surplus country’s gold account at the same place or by physically shipping the gold.

In today’s world, cross border payments generally involve the need to exchange one currency for another at exchange rates that fluctuate. To facilitate the comparison of prices of globally traded goods (e.g., oil, gold, copper, and other commodities) they are generally priced in one common currency. The U.S. dollar is the currency most widely used for this purpose (79%). This contributes to the use of the dollar for cross boarder payments as well even when the buyer’s currency differs from the seller’s ultimate currency (the currency paid to its workers, etc.). https://www.federalreserve.gov/econres/notes/feds-notes/the-international-role-of-the-u-s-dollar-20211006.htm

Some economy is brought to the markets for foreign exchange needed for cross boarder payments by using a common so called vehicle currency as a common go between. The adoption by airlines of a hub and spoke model for connecting all airports in a country or the world illustrates the economy of a single or small number of vehicle currencies (hubs) to exchange currency X for currency Y. The U.S. dollar is the most widely used vehicle currency for this purpose. This is supported by and reflected in the dominance of the dollar in invoicing internationally traded goods and in the foreign exchange reserves of banks (central and commercial) around the world. The Euro is the second most used currency in these ways.

In 2021 40.5% of international payments were made in US dollars.  The use of Euros in international payments and in reserves has moved up to second place behind the dollar at 36.7% of payments.  The Pound sterling is a distant third at 5.9%. Having passed the Japanese yen a few years back for fourth place the Chinese RMB achieved 3.2% of international payments in January of this year from almost zero a decade ago. “China’s currency scores a win during the Olympics”  The Federal Reserve has constructed an “aggregate index of international currency usage.” The dollar has remained in the neighborhood of 70% for the last two decades. https://www.federalreserve.gov/econres/notes/feds-notes/the-international-role-of-the-u-s-dollar-20211006.htm

To pay for things with a currency, one must hold some amount of that currency. It is this demand for dollar reserves resulting from the widespread international invoicing and payments in dollars, that underlies foreign financing of US debt. For starters, about half of dollar currency (actual banknotes) are held abroad. That is the extent to which we pay for imports with cash and the sellers just hold the cash. Foreign central banks hold almost 13 trillion dollars in foreign exchange reserves of which over 7 trillion is in U.S. dollars (much of that is held in the form of US government debt). About 60% of the foreign currency claims of banks are dollar claims.

The dollar grew into its vehicle and reserve currency roles because of the size of the U.S. economy and its extensive trade with the rest of the world, the size and liquidity of financial assets denominated in dollars, public confidence in the stability of the dollar’s purchasing power, and in its trusted contract enforcement (rule of law).

U.S. Benefits from reserve currency status

The so-called exorbitant privilege of a reserve currency–the ability to borrow abroad in your own currency–makes it easier for the U.S. government to finance its military and other expenditures with debt. For countries to accumulate dollar reserves they must have a balance of payments surplus, i.e., they must sell more to the U.S. than they buy from the U.S.. As a result, American’s enjoy cheaper imports and the excess of dollars paid for such imports over those paid back for US exports are held in foreign reserves (generally in the form of US treasury debt).

As an aside, it is simply wrong to attribute much of the so-called offshoring of our manufacturing to the above phenomenon. The somewhat lower exchange rate for the dollar needed to generate the surplus China and other countries need for the trade surplus with which they buy American debt, does make imports somewhat cheaper. However, even if the dollar was totally replaced in foreign reserves and trade balanced, we would continue to be better off producing what we export and importing what China and the others produce and sell to us. Freely pursuing our comparative advantages increases our incomes and the incomes of the Chinese and others selling to us. Free trade is win-win. Contrary to the myth, U.S. manufacturing is at an all-time high. (Manufacturing employment is lower because of increased labor productivity). https://www.macrotrends.net/countries/USA/united-states/manufacturing-output

The U.S. dollar’s dominance in global trade and finance contributes to the existence of the American Empire in two ways. It attracts foreign financing of the U.S. government and its military industrial complex thus reducing the burden of the empire on the American taxpayer and it provides a tool by which the U.S. can impose its will on other countries or individuals in managing its empire. Borrowing to pay our government’s bills is politically easier than raising taxes and avoids (or delays) a debate over guns versus butter. 

Three factors now challenge the dollars reserve currency role. 1) Cumbersome payment technology: Existing arrangements for cross border payments via the Society for Worldwide Interbank Financial Telecommunication (SWIFT) are technically crude and outmoded. 2) Weaponization of the dollar: The U.S. has abused the importance of its currency for cross border payments to force compliance with its policy preferences not always shared by other countries, by threatening to block the use of the dollar. 3) Growing risk of a decline in the dollar’s value: The growing expectation of dollar inflation and the skyrocketing increase in the U.S. fiscal deficit are increasing the risk of holding and dealing in dollars.

The first factor–payment technology–is temporary. It is being modernized. While payment technology (ease, speed, security, and cost of making cross border payments) is important, it is not as important as the features of the currency being paid. As a currency, the dollar excels for the reasons given earlier.

The second factor–weaponization of the dollar–has been growing in importance as the U.S. has increasingly sanctioned trade and dollar payments without broad international support–Iran, etc.  The EU has sought work arounds in Euros. China and Russia are building alternative payment arrangement using China’s Renminbi. Even with the dramatic increase in coordinated sanctions against Russia, restricting the use of dollars is less effective than directly blocking trade. https://wcoats.blog/2022/03/04/how-to-stop-russia-in-ukraine/  The broad support for sanctions on Russia more likely increases support from the dollar as the dominant international currency rather than reducing it. On the other hand, those on the other side (e.g., Russia and China) will work harder to find alternatives. The balance of these contradictory forces is difficult to assess.

The third factor has never been taken very seriously until now. At the end of February (2022) the US national debt was over 30.1 trillion dollars or 125% of US output (GDP). Federal government interest payments on its net debt were $426 billion per annum. But with the increase in inflation, interest rates are rising. Uncle Sam’s debt service payments are likely to double or triple over the next five to ten years, rising to 15% to 20% of the Federal budget. The world still expects the US to regain control of its spending, but the risks of default are creeping up. Paul “Samuelson stated in 2005 that at some uncertain future period these pressures would precipitate a run against the U.S. dollar with serious global financial consequences.” https://en.wikipedia.org/wiki/International_use_of_the_U.S._dollar

It is the second factor, US abuse of its ability to sanction the use of the dollar that is most threatening to push the dollar over the cliff.

The Alternative to the dollar

An internationally defined and issued currency would have a number of advantages over the use of a national currency for cross border payments.

While the value of the dollar has been quite stable for many years, using a basket of major currencies for pricing internationally traded goods and financial instruments would be even more stable. This is what the International Monetary Fund’s unit of account–the Special Drawing Rights (SDR)– offers. The value of one SDR is equal to the current market value of fixed amounts of the US Dollar, Euro, British pound, Japanese yen, and Chinese yuan. Thus, its widespread use for pricing internationally traded goods and financial instruments would provide even greater stability than would any one of these currencies. Every morning when I check movements in the price of oil, I must ask myself whether it was really a change in the price of oil or in the exchange rate of the dollar. See my: “Why the World Needs a Reserve Asset with a Hard Anchor”

The IMF’s SDR can only be held and used by member central banks and a few international bodies. Thus, private SDRs–so called Market SDRs–are needed for payments by the private sector (perhaps issued by the IMF or the BIS). Being issued by an international body, such Market SDRs would have the equivalent of a central bank for settling cross boarder payments allowing the simplifications and economy increasingly available for domestic payments in the domestic currency. `

Moreover, as an internationally issued currency the SDR would be far better protected from the political abuse increasingly experienced with the US dollar and might be expected with the Chinese RMB or other national currencies.

Getting from here to there

But first things first. Before considering the reform of the international monetary system, let’s consider the reform of the dollar–the reform of U.S. monetary policy. The price of the dollar should be fixed to a hard anchor and issued according to currency board rules.

During the heydays of the gold standard (1820-1913) international trade flourished dramatically increasing global incomes and reducing poverty. According to Antoni Estevadeordal, Brian Frantz and Alan M. Taylor “Until 1913 the rise of the gold standard and the fall in transport costs were the main trade-creating forces.” https://www.jstor.org/stable/25053910  However, to cope with WWI, the Great Depression, and WWII, the gold standard failed and was abandoned because of weaknesses in banking systems and because the countries that fixed the value of their currencies to gold did not fully play by the gold standard’s rules.

Under a strict gold standard, the central bank would issue and redeem its currency whenever anyone bought it for gold at the official price of gold. In fact, however, by actively buying and selling (or lending) its currency for other assets whenever it thought appropriate, the Federal Reserve’s monetary liabilities (base money) were partially backed by U.S. treasury bills and other assets. In addition, the fractional reserve banking system allowed banks to create deposit money that was also not backed by gold. The market’s ability to redeem dollars for gold kept the market value of gold close to its official dollar value. However, the gap between the Fed’s monetary liabilities and its gold backing grew until the market (most conspicuously, France) lost confidence in the Fed’s ability to honor its redemption commitment and President Nixon closed the “gold window” in 1971 rather than tighten monetary policy.

Currency Board Rules

A reformed monetary system that returns to a hard anchor (firmly fixed price of the currency for gold or some other asset) should require the Fed to adhere strictly to currency board rules. Such rules oblige a central bank to buy and sell its currency at a set price in response to public demand. Under the Gold Standard, the price of the currency was set as an amount of gold (a gold anchor). For existing currency boards, the price is typically an amount of another currency or basket of currencies. See my book on the establishment of the Central Bank of Bosnia and Herzegovina (“One currency for Bosnia-creating the Central Bank of Bosnia and Herzegovina”).    The Fed would provide the amount of dollars demanded by the market by passively buying and selling them at the dollar’s officially fixed price for its anchor. All traditional open market operations by the Fed in the forms of active purchases and sales of T-bills or other assets would be forbidden.

The Anchor

Another weakness of the historical gold standard was that the price of the anchor, based on one single commodity, varied relative to other goods, services and wages. While the purchasing power of the gold dollar was relatively stable over long periods of time, gold did not prove a stable anchor over shorter periods relevant for investment.

Expanding the anchor from one commodity to a basket of 5 to 10 commodities with greater collective stability relative to the goods and services people actually buy (as measured by, e.g., the CPI index), would reduce this volatility. The basket would consist of fixed amounts of each of these commodities and their collective market value would define the value of one dollar.  There have been similar proposals in the past, but the high transaction and storage costs of dealing with all the goods in the valuation basket doomed them. However, with indirect redeemability discussed next, the valuation basket would not suffer from this problem.

Indirect redeemability

Historically, gold and silver standards obliged the monetary authority to buy and sell its currency for actual gold or silver. If the dollar price of gold in the market was higher than its official price, people would buy gold at the central bank increasing its market supply and reducing the money supply until the market price came down again. These precious metals had to be stored and guarded at considerable cost. More importantly, taking large amounts of gold and silver off the market distorted their price by creating an artificial demand for them. A new gold standard would see the relative price of gold rising over time due to the increasing cost of discovery and extraction. The fixed dollar price of gold means that the dollar prices of everything else would fall (deflation). While the predictability of the value of money is one of its most important qualities, stability of its value, such as approximately zero inflation, is also desirable.

Indirect redeemability eliminates these shortcomings of the traditional gold standard. Indirect redeemability means that currency is issued or redeemed for assets of equal market value rather than the actual anchor commodities.  Market actors would still have an arbitrage profit incentive to keep the supply of money appropriate for its official value.  As the economy grows and the demand for money increases, this mechanism would increase the money supply as people sell their T-bills to the Fed for additional dollars at its official (gold or whatever) price.

Towards a global anchor

The United States could easily amend its monetary policy to incorporate the above features – adopting a government defined value of the dollar as called for in Article 1 Section 8 of the U.S. Constitution and a market determined supply. The Federal Reserve would be restricted by law to passive currency board rules. Additional financial sector stability would be achieved by also adopting the Chicago Plan of 100% reserve requirements against demand deposits. This would be a natural byproduct of the Fed creating a two-tier Central Bank Digital Currency (CBCD) now under consideration.

The gold standard was an international system for regulating the supply of money and thus prices in each country and between countries and provided a single world currency (via fixed exchange rates). Balance of trade and payments between countries was maintained (when central banks played by the rules) because deficit countries lost money (gold) to surplus countries, reducing prices in the former and increasing them in the latter. This led to a flourishing of trade between countries. This was a highly desirable feature for liberal market economies.

The United States could adopt the hard anchor currency board system described above on its own and others might follow by fixing their currencies to the dollar as in the past. The amendments to the historic gold standard system proposed above would significantly tighten the rules under which it would operate and strengthen the prospects of its survival.

However, there would be significant benefits to developing such a standard internationally. One way or the other, replacing the fluctuating exchange rates between the dollar and other currencies with the equivalent of a single currency would be a significant boon to world trade and world prosperity.  Replacing the U.S. dollar as the world’s reserve currency with an international unit would have additional benefits for the smooth functioning of the global trading and payments system.  

In a small step to create an internationally issued currency the IMF created its Special Drawing Right (SDR) in 1969 in the expectation of supplementing the gold-based US dollar. But in today’s world of fiat currencies with floating exchange rates the SDR has several limitations as a reserve currency, most of which can be lived with for a while. The SDR allocated by the IMF can only be held and used by the central banks of IMF member countries and a few international organizations such as the World Bank and BIS. The SDR falls short as a challenger to the US dollar because of the absence of widespread private market use of the unit.

To become a serious supplement to, if not replacement for, the US dollar in the international monetary system the SDR would need to be usable for payments by private sector parties. This would require the creation of private or Market SDRs. This could be done in much the same way banks now create dollar deposits.

Digital SDR currency

As with national currencies, the internationally issued SDR needs a central issuer of the base money version of market SDRs (M-SDRs). The IMF should oversee the develop of a procedure for issuing M-SDRs following currency board rules and backed 100% by official SDRs or by an appropriate mix of sovereign debt of the five basket currencies.

The IMF might establish an IMF trust fund that would issue M-SDRs to AAA or AA international banks upon their request and payment of the equivalent value of one or more of the five basket currencies (and would redeem them under similar arrangements). As with other IMF trusts, the IMF might approach the BIS to operationally manage the issuance and redemption of M-SDRs and the maintenance of the official SDR asset backing (or its equivalent in the five currencies in the valuation basket).

Banks offering M-SDR deposits/currency to their customers would hold an M-SDR reserve backing with the IMF SDR trust fund. The base money M-SDRs issued by the IMF trust fund would perform the same payment settlement function as do central banks for the base money they issue, with the critical difference that its depositors/participants would be global rather than national. This would enable virtually instantaneous final settlement of M-SDR payments globally.

An M-SDR would facilitate and be facilitated by invoicing internationally traded goods and financial instruments in SDRs. More, if not most, internationally traded commodities could and should be priced in SDRs. Cross border borrowing can and should be denominated in SDR starting with bond issues and lending by international development institutions (as is now the case with the IMF, and to a very limited extent the World Bank).  https://www.brettonwoods.org/article/proposal-for-an-imf-staff-executive-board-paper-on-promoting-market-sdrs

To go all the way with SDRs, the IMF’s Articles of Agreement would need to be amended to replace the allocation of SDRs with issuing them according to currency board rules as discussed earlier. Furthermore, the valuation basket that now consists of key currencies would need to be replaced with a commodity basket as outlined in my Real SDR Currency Board proposal: (http://works.bepress.com/warren_coats/25/).

The shift from dollar to SDR international reserves, payments, and invoicing would give the world a more stable currency for all of these purposes. This would further promote trade because of more efficient cross boarder payments thus further lifting incomes around the world. Being an internationally issued and controlled currency, the potential for its political abuse by the U.S. would be greatly reduced. But eliminating the seigniorage that the U.S. now enjoys supplying its currency to the rest of the world, i.e., the foreign financing of some of its debt, would remain without further measures.

As central banks and foreign firms shifted from dollars to SDRs they might simply transfer the US treasury bills (and other US investments) that they now hold to the issuers of the M-SDRs. In that case the U.S. would continue to enjoy its exorbitant privilege of foreign financing in exchange for holding its currency. In this case M-SDRs rather than USD would also be backed by US debt. Thus, rules are need for what currency or assets must be paid to buy M-SDRs and/or what assets M-SDRs are backed by. This could take the form of buying M-SDRs with USD but the issuer exchanging the dollars for a more balanced portfolio of assets. While the SDR value continues to be defined by a basket of currencies, the assets backing issued SDR might reflect the same proportions of the same currencies.

The reduction in this way of the role of the dollar as a reserve currency would be win win. It would provide for more stable and more efficient international trade and payments. It would help demilitarize money and it would modestly increase the cost of US debt finance, hopefully encouraging more careful spending.

Econ 101:  How to help Afghans?

The world is rightly looking for ways to help Afghans without helping the Taliban (until or unless the Taliban forms a government the world is willing to recognize). Washington Post: “How to help Afghans without aiding Taliban”  In this Post article Anthony Faiola states that “The biggest problem isn’t a lack of food. Rather, it’s the disappearance of what had been the lifeblood of the Afghan economy — Western cash.” This mischaracterizes the problems of Afghans thus confusing our understanding. In this note I attempt to clarify the “cash” aspect of Afghanistan’s problems.

But first there is no escaping the fact that the cut back of foreign aid is reducing the income (and the goods that income buys) available to Afghans. Mention is often made of the approximately 10 billion US dollars of the Afghan government’s funds frozen in deposits abroad. These funds cannot be used until a new Afghan government is recognized with the authority to claim them. But these funds are not part of the lost revenue to the Afghan government. They are the wealth–the previous income saved–of the government (whoever that will turn out to be). The savings that we accumulate from our incomes for retirement or whatever is our wealth not our current income (though it can be drawn on to augment current income).

In recent years (prior to the Taliban take over) the Afghan government’s operating expenditures were 16 to 18% of Afghanistan’s GDP while its domestic revenue was 12 to 14% of GDP. The balance of its financing plus all development expenditures were from donors. The hope is that squeezing the Taliban “government” financially will add to the incentives for them to quickly form an inclusive government meeting international norms of human rights. Unfortunately, it is not possible to shut off the flow of funds to the government without also starving the Afghan people.

While the Ghani government has been replaced (temporarily) by Taliban leaders, the institutions (ministries and agencies) of government remain, but with new management. Of the government’s operating expenditures roughly 80% was for wages and salaries. Thus, the government could more or less finance its wage and salary expenses from its own domestic revenue without donor support. Indeed, all salaries have been and continue to be paid in the central bank (Da Afghanistan Bank — DAB) and presumably in the other government ministries as well, albeit with delays. However, the real value of these incomes is being reduced because of increased inflation (an indirect form of taxation). DAB and other government agencies have largely stopped providing economic and financial data since the Taliban take over.  IMF First-Review-Under-the-Under-the-Extended-Credit-Facility

None the less, freezing Afghanistan’s deposits abroad (DAB’s foreign exchange reserves held abroad) has created monetary problems within Afghanistan because of the inability to import the cash (dollar banknotes) on which the economy depends. Afghanistan remains a largely cash economy. Most payments are made in cash. Though inflation has been low in recent years (generally 2-4%), inflation in earlier decades was relatively high and thus Afghans held and transacted in US dollars quite extensively. Around 70% of bank deposits are in dollars. The availability of USD banknotes for local payments is thus very important. These were mostly supplied by the New York Federal Reserve Bank from the dollar deposits that DAB maintains there (and now frozen).

Prior to the Taliban takeover, the normal operation of DAB’s monetary policy consisted of receiving US dollars from the government (largely from donor grants) and depositing the equivalent value of Afghani in the government’s accounts. The government disbursed these Afghani to its employees in wage and salary payments (generally by electronic deposits to employee bank accounts). Without offset, the resulting creation and injection of these Afghani would be inflationary. DAB drains (buys back) this excess base money by auctioning some of the dollars it received from the government (sufficient to stabilize the dollar exchange rate) and capital notes of DAB. The government’s deposits of dollars with DAB took the form of credits to DAB’s dollar account with the New York Fed. From these deposits DAB pays the Federal Reserve to fly USD banknotes to Kabul as needed for DAB’s dollar auctions.

In mid-April 2021, when the U.S. announced its intention to withdraw the rest of its military personnel by September, an increased outflow of dollars by Afghans wanting to protect their wealth put the Afghani exchange rate under pressure. Acting DAB Governor Ajmal Ahmady (his appointment was never approved by Parliament) increased dollar auctions to stabilize the exchange rate. “Afghan central bank drained dollar stockpile before Kabul fell” As the amount of dollars in its vaults ran down, it used USD banknotes that it held on behalf of banks (approximately $700 million USD). The delivery of additional cash from New York expected in July never arrived and DAB’s balances at the New York Fed are now frozen until a new government is recognized so that no more dollar cash can be purchased from the Federal Reserve by DAB.

As an aside, I was surprised during a 2009 visit to Zimbabwe—as part of an IMF team following Zimbabwe’s dramatic hyperinflation during which it dollarized—to learn that there was an active private market in dollar banknotes supplying Zimbabwe from South Africa:  “Hyperinflation in Zimbabwe”

In the days just before and after the American evacuation in August 2021 public demands to withdraw dollar cash intensified but DAB had largely used up the dollars in its vaults (both its own and those held for banks). In response, on August 14 DAB imposed limits on the amounts that could be withdrawn each day. This fed public concern that their banks were running out of dollar banknotes and triggered runs on the banks. DAB was even running low on Afghani banknotes, which might have replaced dollars. Without access to its deposits abroad DAB is unable to purchase additional dollar cash nor pay for printing additional Afghani. For a largely cash and heavily dollarized economy this drying up of cash liquidity is very disruptive and the basis of the statement that people can’t buy the food that might be available.

In addition to the cash shortage, Afghans are also lining up to withdraw their deposits out of concern for a possible bank failure. Aid cut offs and civil strife have damaged many firms resulting in arrears on their bank loan payments. This threatens to push bank illiquidity into insolvency. Even if DAB had USD and AFN cash to lend or sell to banks with fully performing loans, DAB is currently unable to buy or lend against these illiquid bank assets. Moreover, the Office of Foreign Assets Control (OFAC) of the U.S. Treasury has sanctioned payments to many Afghan entities and activities blocking many payments to and from abroad by Afghan banks and uncertainly about the application of the sanctions regime has made banks overly cautious about executing payments for their customers.

UN and other aid organizations have experience in other countries with delivering wages and other payments to targeted recipiences (teachers, healthcare workers and potentially even government employees) without the funds passing through the government’s hands. This approach is needed and is being developed for use in Afghanistan. OFAC sanctions are being modestly relaxed and UN and other aid agencies have begun funding the importation of dollar cash for humanitarian assistance projects. The use of digital mobile phone payments, such as M-Paisa and HesabPay, should be promoted and exploitation to the extent possible.  “Use of mobile phone payments” The United States needs to and has been gradually relaxing its payment restrictions to make this possible.

The Taliban leadership needs to take urgent steps to establish a new inclusive government that can and will be recognized internationally thus unfreezing Afghanistan’s (and DAB’s) deposits abroad and eliminating its cash shortage and restoring development assistance. In the meantime, in addition to the urgent need for humanitarian assistance that bypasses the Taliban, the New York Federal Reserve, or any other doners, should consider a loan to DAB to finance immediate shipments of dollar banknotes to Kabul. Da Afghanistan Bank Law adequately protects the central bank from government interference in its conduct of monetary policy and bank supervision. As a condition for restoring USD currency shipments to DAB, the Federal Reserve (and the UN) should obtain an agreement from the Taliban government to fully respect that law and appoint qualified people to its Supreme Council and Executive Board.

Until Afghanistan has a proper government, and its economic development can resume, Afghans, many of whom are very poor to begin with, will suffer unnecessarily depressed incomes. The lack of cash is adding a further, tragic, and quite unnecessary disruption to the lives of a long-suffering people. This can be and should be fixed urgently. Any such assistance will somewhat reduce the financial pressure on the Taliban, but a total financial squeeze on the government will fall on the people of Afghanistan as well.

Econ 101: Erdogan’s Turkey

President Erdogan believes that by cutting interest rates on the Turkish lira the resulting depreciation of its exchange rate will cheapen Turkish goods and thus increase their exports and promote growth (the China model, he thinks). Accordingly, he has replaced four central bank governors who could not bring themselves to accede to his demands. “Revolving door-Turkeys-last-four-central-bank-chiefs”

In an earlier disastrous cycle, the Central Bank of Turkey (CBT) reduced its policy rate from 24% in 2019 in steps to 8.5% in mid 2020 only to raise it again to 19% in March 2021 until the latest cuts started in September of this years. In November, “The Monetary Policy Committee (MPC) has decided to reduce the policy rate (one-week repo auction rate) from 15 percent to 14 percent.” “Press Releases/2021/ANO2021-59”  

When I was part of the IMF team in 2000-1 working with the Turkish authorities to regain control of inflation (which ranged from 60 and 100 percent between 1980 and 1999) and clean up the banking sector (they closed 13 banks in 2000), the CBT policy interest rate was briefly raised to 100% (ala Paul Volcker in the US). Inflation declined rapidly to single digit levels (until the last four years) with interest rates quickly following.

The dollar price of the Turkish lira has fallen in half since February of this year (i.e., a dollar will buy twice as many lira–one lira cost 0.14 dollars in February and 0.061 dollar on December 17).  Erdogan seems to think he is choosing to benefit workers (exporters) over consumers (importer), though they are generally the same people.  If the lira depreciates, the rest of the world can buy lira more cheaply and thus (according to Erdogan) will buy more cheaper Turkish exports. This should increase the demand for Turkish good and the jobs that produce them and increase the growth of the Turkish economy.

As any economist can explain to Mr. Erdogan, depreciating the exchange rate with lower interest rates in Turkey than in the rest of the world is achieved by printing more money with which to buy foreign currencies. Broad money (M2) increased almost 48% in November 2020 from a year earlier and 24% from a year earlier this November. But such a rapid increase in the money supply will increase prices in Turkey over and above the increase in the price of imports from the lira’s depreciation. “Turkey-central bank-Erdogan”

Inflation in Turkey has risen from single digits between 2004 to 2016 to “21.3%” in November 2021 (annual rate from a year earlier). According to the Central Banking Journal “Official figures show Turkish inflation reached 21.31% year-on-year in November, but there is considerable controversy over whether these figures are accurate. Several well-informed observers, have told Central Banking that they believe the official figures understate actual inflation.”  “Turkey’s currency hits new low after further rate cut”  Steve Hanke reports the actual rate at around 100%  “Steve Hanke’s estimate of Turkey’s inflation rate”

In short, Mr. Erdogan’s crazy policy of reducing interest rates has not made Turkish goods cheaper for the rest of the world. As the lira became cheaper for foreigners (depreciation), the lira price of those goods became more expensive (inflation). The real effective exchange rate (which takes account of both) is not being significantly reduced because Turkey is experiencing higher and higher inflation along with the lira’s depreciation.

Econ 101: Inflation –Temporary or Longer Lasting?

Prices of many goods and services have increased in recent months. Are these increases permanent or temporary or will they continue rising in the future? Before exploring those questions, it is important to understand the measures of inflation we are considering. What is the current rate of inflation in the United States? U.S. inflation in September was 3.0% (Compound annual rate of change for Consumer Price Index without food and energy prices over the month of September), or 4.0% (percent change from a year ago) or 5.4% (percent change from a year ago including food and energy prices). What does it mean if this is temporary or long lasting?

If prices remain where they are today after the 5.4% increase from a year ago, inflation going forward would be zero even though the cost of living would be permanently higher. If inflation is long lasting it means that prices will continue to rise for some time (years). What are the factors that influence the future behavior of prices? What should we expect in the U.S.?

The price of a good or service increases when its demand exceeds its supply and similarly for prices in general (when aggregate demand exceeds aggregate supply). As prices are measured in a country’s currency, supplying too much of the currency (generally when the money supply grows more rapidly than the supply of goods and services) causes its value to fall (i.e., prices in the country’s currency to rise).

On the cost side, firms will hire workers and pay them a particular wage (and related benefits) when it adds more to the company’s income than it costs, which includes the cost of the tools they use (capital). Workers will accept a job when its benefits (pecuniary and nonpecuniary) are the best they can find. The inflation expected by the employer and the employee over the period of the wage contract is an important factor in determining what will be offered and what will be accepted.

Because of changes in consumer demands, worker preferences, halving of work visas for immigrants, and supply chain disruptions, labor markets are temporarily in turmoil. September unemployment in the U.S. was 7.674 million while there were 10.4 million job vacancies. Employers are raising wages in an effort to fill those vacancies. As reported by Scott Lincicome: “Goldman Sachs analysts saw a ‘perfect storm of factors that have significantly reduced the supply of workers who are currently looking for jobs at the same time that labor demand—as measured by job openings—has risen to an all-time high.’ This includes… state and federal benefits, early retirements, severely restricted immigration, a switch to self-employment, fear of COVID, and a geographic mismatch between unemployed workers and available jobs. Combined, these factors account for most of the missing workers out there.”  “What if the labor shortage isn’t transitory?”

In short, the labor force has shrunk just as the demand for output is increasing. This excess demand for workers is driving up labor costs and thus pushing up output prices. If the 5 or 6 percent price increase experienced over the present year is expected to be temporary, i.e., if prices are expected to return to their level a year ago, because the supply of labor returns to its pre-pandemic level, wage increases should be temporary as well, falling back to their pre pandemic level and growing thereafter on average with labor productivity plus the 2% inflation target of the central bank once there is full employment and better labor market balance.

More likely, if the inflation is expected to be temporary, i.e., the current 5 to 6 percent inflation stops but prices remain at their increased level, wages will remain at the increased level, but their real (inflation adjusted) value will fall back to their original level. In other words, if these higher prices are expected to be “permanent,” the nominal wage increases now being experienced will not result in any increase in real wages and the worker short fall might remain.

While some of those who withdrew from the labor force will probably return, it is not likely to fully satisfy the demand for various reasons (early retirement, fall in immigration, etc.). Filling (or attempting to fill) the remaining labor shortage will require additional wage increases (unless the public’s demand for goods and services falls–see below). In that case, firms will plan to pass on their higher cost of labor to their customers. If we, the customers, can continue to pay the higher prices, the inflation will continue. Expectations of higher prices and or inflation will be realized.

The Covid-19 pandemic caused a sharp fall in output and thus to most people’s incomes. The government provided extraordinary financial support to temporarily fill the resulting income gap. Such support did not increase the output of goods and services or even prevent their decline but rather temporarily redistributed income from those saving it to avoid hunger and defaults on rents, mortgages, and other financial obligations by those who lost it.  “The new covid-19 support bill”  Because personal incomes were substantially maintained while actual output fell, personal savings rates increased dramatically and continue to be well above pre pandemic levels.

The Federal Reserve pitched in by buying up huge amounts of the resulting government debt increasing its balance sheet from $3.5 trillion in February 2020 to $6.3 trillion in August 2021 (measured by the monetary base, M0). This fueled an increase in board money (M3–M0 plus bank deposits and similar liquid assets of the public) from $15.5.0 trillion in February 2020 to $20.8 trillion in August 2021. This increase, though substantial, was significantly less than the increase in M0 (which almost doubled) because the Fed paid interest to banks for keeping the new base money with the Fed (excess reserves) rather than lending it to the public, by paying banks interest on all bank reserves kept with the central bank.

Historical experience is that the public will not be willing to hold these larger amounts of money for ever. They will eventually attempt to spend them down to their traditional (normal) levels, thus adding to aggregate demand for goods and services (and inflationary pressure).

Eventually, the demand for goods and services (aggregate demand) must fall to match real output, or output must rise to match demand. But if the Federal Reserve continues to print money faster than its real value is being inflated away, the inflationary process will continue or accelerate. Similarly, if the government continues to redistribute income from those with a lower propensity to consume (generally higher income families with a higher savings rate) to those with a higher propensity to consume (generally lower income families that save little), aggregate demand will remain excessive perpetuating inflation.

Historically, hyperinflation episodes invariably exploded in the collapse of the currency.  “Hyperinflation in Zimbabwe”  Turkey has come closest to a high inflation “equilibrium.” From the mid 1980s to the end of the 1990s Turkey’s inflation rate varied between 80 and a 120 percent. A high inflation “equilibrium” would be characterized by nominal interest rates and wage rates that fully incorporate the ongoing expected rate of inflation in order to preserve the appropriate real (inflation adjusted) rates. Interest rates in Turkey in this period generally exceeded 100%, as did wage growth.

In its most recent World Economic Outlook, the International Monetary Fund stated that: “In settings where inflation is rising amid still-subdued employment rates and risks of expectations de-anchoring are becoming concrete, monetary policy may need to be tightened to get ahead of price pressures, even if that delays the employment recovery.” “World Economic Outlook-October 2021

As stands out clearly from the increasingly but unevenly rising inflation in the 1970, the process of increasing inflation is not linear (see the chart above).  As inflation increased, the Federal Reserve tightened monetary policy (raised interest rates to slow monetary growth) to slow inflation, causing real output to slow or decline. Policy then eased prematurely, and inflation and the expectation of higher inflation took off again, each time reaching a higher peak (until Paul Volcker stepped on the breaks and ended the game in 1979-80–the exciting year I worked at the Federal Reserve Board).

The Federal Reserve is smarter today than it was in the 1970s and has the tools to prevent the acceleration of inflation and the unhinging of inflation expectation. But the excess money balances and personal saving are very large and the government’s seeming willingness to run up unprecedented deficits create a powerful inflationary head wind. The tightening of monetary policy that will be needed (sooner rather than later in my view) will reduce the Fed’s purchases of Treasury debt and increase interest rates. Higher interest rates will increase government spending for debt service on its very large stock of debt, which will further increase government borrowing and debt or require cuts in spending for other programs. This must be added to the economic challenges of confronting climate change, the continuing recovery and adjustments from the Covid-19 pandemic, the deepening and destructive partisan divide that is stifling Congress, and the growing lack of public trust that drives it.

Whether our current inflation is temporary or longer lasting depends on how quickly and decisively the Federal Reserve tightens monetary policy and how quickly people go back to work. Whether the U.S. economy and the government’s large stock of debt continue to enjoy safe haven status around the world depends heavily on whether our government brings its spending and tax policies under better control.

A shift in monetary regimes?

By Warren Coats[1]

This Sunday, August 15, is the 50th anniversary of President Richard Nixon’s closing of the gold window as part of the “Nixon Shock.” “Fifty years later Nixon’s August surprise still reverberates”  He announced on that day that the U.S. Treasury would no longer redeem its dollars for gold at $35 an ounce. Over the subsequent few years, the world moved from national currencies whose values were anchored to the market value of gold, to currency values determined by central banks’ regulation of their supply relative to the market’s demand. The value of one currency for another floated in the foreign exchange market. Central banks have deployed various approaches to determining the supplies of their currencies and most have now settled on targeting an inflation rate (often 2% per year) in one way or another.

With the rapidly increasing interest in cryptocurrencies, some have asked whether we are on the brink of another monetary paradigm shift? Specifically, might the dollar be replaced as the dominant international reserve currency. To explore that question we need to understand how the existing monetary systems work and how the widespread use of cryptocurrencies might add to or change these systems.  

In describing the existing and potential future monetary systems, we need to distinguish “money” from the “means of payment.” Money is the asset that people accept in payment of debts or for the purchase of goods and services. The U.S. dollar and the Euro are “money.” The means of payment refers to how money is delivered to the person being paid. Do you personally hand dollar bills and coins to the Starbucks cashier, write out a check (bank draft) and put it in the mail, or electronically transfer “money” from your bank account to an Amazon merchant via eWire, Zelle, Venmo, PayPal, or some other digital payment service? Or perhaps you purchase goods and services with borrowed money (Visa, MasterCard, American Express) that you pay back at the end of each month or over time. Or if you don’t have a bank account (a form of digital money) you might hand-deliver physical currency to a Hawala dealer or a MoneyGram or Western Union office to be electronically transferred to their office nearest to the person you are sending it to, potentially anywhere in the world. If you are paying in a currency that is different than the one the payee wishes to receive, your currency will be exchanged accordingly along the way in the foreign exchange market.

Discussions of cryptocurrencies include both the latest and evolving means of payment (digital payment technologies) as well as new, privately created moneys such as bitcoin, Ethereum, or Ripple.  Private currencies vary enormously with regard to how their value is determined. By private currencies I do not mean privately created assets redeemable for legal tender, such as our bank accounts. When we speak, for example, of the U.S. dollar, we invariably include dollar balances in our bank accounts, dollar payments made via our Visa card, etc. These are all privately produced assets that are ultimately redeemable for Federal Reserve currency or deposits at a Federal Reserve Bank. They are credible claims on the legal tender of the United States. Most U.S. dollars are privately created.

The value of all money is determined by its supply and demand. The demand for money arises from its acceptability for payment of our obligations and the quantity of such obligations (generally closely related to our incomes). Within each country, its legal tender money (e.g., the U.S. dollar in the U.S.) must be accepted by payees. In particular, it must be accepted by the government in payment of taxes.  Truly private currencies (those not redeemable for legal tender, of which there are over 11,000 at last count) have a serious challenge in this regard. Very few people or businesses will accept bitcoin, or any other such private cryptocurrency. As a result, the demand for such currencies for actual payments is very low. The demand for bitcoin, for example, is almost totally speculative–a form of gambling like the demand for lottery tickets. Such private currencies are more attractive in countries whose legal tender is rapidly inflating or has unstable value (e.g., Venezuela). 

The acceptability of a currency in cross border payments raises special challenges. My currency is not likely to be the currency in general use in other countries. Someone in Mexico paying someone in Germany will generally have Mexican pesos and the recipient in Germany will want Euros. The pesos will need to be exchange for Euro in the foreign exchange market. It would be very costly for dealers in the FX market to maintain inventories of and transact in every bilateral combination of the world’s 200 or so currencies. It has proven more economical to exchange your currency for U.S. dollars and to exchange the U.S. dollars for the currency wanted by the payee. The dollar has become what is called a vehicle currency.

The economy of a so-called vehicle currency can be illustrated with languages. Two hundred and six countries are participating in the 2021 Olympic Games in Japan. To communicate with their Japanese hosts participants could all learn Japanese. It is unrealistic to expect the Japanese hosts to learn 205 foreign languages. But what about communicating with their fellow participants from the other 205 countries. For this purpose, English has become the default second language in which they all communicate. Unlike more isolated Americans, most Europeans speak several languages, but one of them is always English. English as the common language is the linguistic equivalent of the dollar as a vehicle currency.  

The rest of the value of money story focuses on its supply. Bitcoin has the virtue of having a very well defined, programmatically determined gradual growth rate until its supply reaches 21 million in about 2040. The supply today (Aug 2021) is 18.77 million. See my earlier explanation: “Cryptocurrencies-the bitcoin phenomena”  The other 11,000 plus cryptocurrencies each have their own rules for determining their supply, some explicit and some rather mysterious. The class of so called “stable coins” are linked to and often redeemable for a specific anchor, sometimes the U.S. dollar or some other currency. The credibility of these anchors varies.

The highly successful E-gold (from 1996-2006) is an example of a digital currency that had well-defined and strict backing and redemption for a commodity at a fixed price. “E-gold”  The supply of such currencies is determined by market demand for it at its fixed price–what I have elsewhere called currency board rules. I describe how currency board rules work in my book about establishing the Central Bank of Bosnia and Herzegovina:   “One currency for Bosnia-creating the Central Bank of Bosnia and Herzegovina”

The dominance of the U.S. dollar in cross border payments reflects far more than its use as a vehicle currency. Many globally traded commodities, such as oil, are priced in dollars and thus payments for such purchases are settled in dollars. Pricing a homogeneous commodity trading in the global market in a single currency makes that market more efficient (the same price for the same thing).  Making cross border payments in dollars (or any other single currency) also avoids the costly need to exchange one for another in the FX market. The dollar is most often chosen because its value is relatively stable, and it has deep and liquid securities markets in which to hold dollars in reserve for use in cross border payments.

So, what are the chances that current cryptocurrency developments might precipitate a shift from the dollar to some other currency and means of payment. Several factors of U.S. policy have heightened interest by many countries in finding an alternative.  Specifically, from my recent article in the Central Banking Journal on the IMF’s $650 billion SDR allocation:

Cumbersome payment technology. Existing arrangements for cross-border payments via Swift are technically crude and outmoded.

The weaponization of the dollar. The US has abused the importance of its currency for cross-border payments to force compliance with its policy preferences that are not always shared by other countries, by threatening to block the use of the dollar.

The growing risk of the dollar’s value. The growing expectation of dollar inflation and the skyrocketing increase in the US fiscal deficit are increasing the risk of holding and dealing in dollars.”  “The IMF’s 650bn SDR allocation and a future digital SDR”

Most central banks are upgrading their payment systems. But the Peoples Bank of the Republic of China (PBRC) is one of the most advanced in developing a central bank digital currency (CBDC), the e-CNY. However, it has little potential for displacing the dollar for several reasons. The Federal Reserve is also modernizing its payment technology, including exploring the design of its own CBDC, and can match China’s payment technology in the near future if necessary. More importantly, China’s capital controls, less developed Yuan financial markets, and less reliable rule of law make the Yuan an unattractive alternative to the dollar. These latter impediments do not apply to the Euro, however. “What will be impact of China’s state sponsored digital currency?”

Rather than looking for another national currency to replace the dollar, there are several advantages to using an international one. These include greater ease in making cross border payments and the reduced risk of political manipulation, or a national currency’s domestic mismanagement.  Bitcoin, for example, can make payments anywhere in the world without being controlled by any one of them. The serious drawbacks of Bitcoin’s blockchain payment technology might be overcome with one or another overlaid technology. But to become a serious currency, bitcoin must be dramatically more widely accepted in payment than it is now. Widespread acceptance in payments could generate the demand to hold them for payments, which would tend to stabilize its very erratic value. This seems very unlikely. A digital gold-based currency, such as the earlier E-gold, would enjoy the advantage of an anchor that is well known and that has enjoyed a long history. However, gold’s value has been very unstable in recent years. Aluminum has enjoyed a very stable price and elastic supply and will be the anchor for Luminium Coin to be launched in the coming weeks: https://luminiumcoin.com/

But the world has already established the internationally issued and regulated currency meant to supplement if not replace the dollar, the Special Drawing Rights of the International Monetary Fund. The IMF has just approved a very large increase in its supply.  “The IMF’s 650bn SDR allocation and a future digital SDR”  The SDR’s value is determined by the market value of (currently) five major currencies in its valuation basket. While all five of these currencies have a relatively stable value, the value of the basket (portfolio) of these five is more stable still. The rules for determining the SDR’s value and supply, as well as its uses, are well established and transparent and governed by the IMF’s 190 member countries. In short, the SDR is truly international. However, it can only be used by IMF member countries and ten international financial institutions such as the World Bank and the Bank for International Settlements.

While the SDR has played a limited useful role in augmenting central bank foreign exchange reserves, it has failed to achieve a significant role as an international currency because of the failure of the private sector to invoice internationally traded goods and financial instruments (such as bonds) in SDRs and the absence of a private digital SDR for payments. If the IMF is serious about making the SDR an important international currency it should turn its attention to encouraging these private sector uses of the unit. “Free Banking in the Digital Age”

In the long run the IMF should issue its official SDR according to currency board rules and anchor its value to the market value of a small basket of commodities rather than key currencies: “A Real SDR Currency Board”

Bitcoin Excitement

Interest in bitcoin is growing. Its promotors are generally good guys wanting to provide the world a better payment system. Its users are often bad guys happy to move their ill gotten money pseudo anonymously (though the Feds tracked down and recovered some of the ransomware paid in bitcoin by Colonial Pipeline). 

Ezra Fieser reports in Bloomberg on a fascinating effort in the El Salvadorian village of El Zonte to expand the use of Bitcoin for making payments.  [“World’s biggest bitcoin experiment is a surf town in El Salvador”]  On June 9th, El Salvador approved President Nayib Bukele’s proposal to add Bitcoin to the U.S. dollar as legal tender in the country (El Salvador does not have its own currency).  El Zonte has no bank, thus storing money and making payments of it from a smart phone wallet would be very attractive.

Michael Peterson is the acknowledged father of efforts to establish bitcoin in El Zonte. The requirements for its use are apps for acquiring, storing, and paying bitcoin on smart phones and the proliferation of people and merchants with such apps willing and able to deal in bitcoin. Peterson “used Wallet of Satoshi, one of the many existing smartphone apps created for small transactions using Bitcoin, which is notoriously impractical—expensive and slow—for everyday purchases.  As more stores began asking how they could accept Bitcoin, Peterson decided El Zonte needed its own app. The Bitcoin Beach Wallet, which launched in September, similarly uses technology that allows for small transactions.” [Bloomberg, ibid]

Bitcoin ownership and transactions are recorded on blockchains that are replicated thousands of times around the world and publicly accessible. Blockchain is a slow and expensive approach to record keeping, but avoids the so called “trusted third party” of, say, a bank account ledger. Thus, work arounds have been developed for small payments that can be spent without the slow and cumbersome mining that prevents double spending for digital currencies on distributed ledgers (e.g., blockchain).  Despite the touted attraction of avoiding a “trusted third party”, most bitcoin users hold them with exchanges such as CoinDesk. These exchanges also facilitate finding sellers for those wishing to buy bitcoin and buyers for those wishing to sell them. Bitcoin traders no longer gather in park meetings that brought buyers and sellers together. [“The future of bitcoin exchanges”]

But the value of bitcoin has been highly unstable. On April 15 Bitcoin traded at $64,829.14, rising unevenly from virtually nothing starting in July 2010. On May 23, it traded for $31,248.42 and as I write this it is trading at $34,616.24, not exactly a stable value.

Thus, bitcoin has not been used to fulfill one of the key functions of money, i.e., to set prices. Though a growing (but still relatively small) number of establishments in El Zonte will accept bitcoin, they all price their goods and services in U.S. dollars. Thus, before bitcoin can be used for payment, an exchange rate (bitcoin equivalent of the required dollar amount) must be agreed. 

To succeed and be widely accepted and used as a currency, the value of bitcoin will need to become much more stable. In fact, to be competitive with the dollar or other sovereign currencies, bitcoin will need to become more stable than its competitors. Improving payment technology can be used for the dollar or any other currency, so the issue is the currency itself rather than the technology for paying it.  See the very successful example of M-Pesa in Kenya. That technology is very unlikely to rely on the clunky blockchain. Even Facebook’s Libra (now called Diem) only pretended to use blockchain, stating that it intended to switch to blockchain in the future. [“Bitcoin, cybercurrencies, and blockchain”]

As explained in my first article on bitcoin written over seven years ago [“Cryptocurrencies-the bitcoin phenomena”] the value of bitcoin or any other currency results from the matching of its supply with its demand at a particular value. Achieving that equilibrium requires either an adjustment in its supply or in its value. Widespread use of bitcoin for payments (rather than just speculative investments) will create demand to hold it for future payments. Bitcoin’s supply is totally predictable. It is growing gradually to a maximum of 21 million units by the year 2040. The supply is currently 18.74 million. Thus, its value depends on what happens to its demand for payments.

While the demand for money (dollars or whatever) tends to be relatively stable in relation to income over moderate periods of time, it is subject to seasonal and other temporary short-term fluctuations.  In the search for a rule based monetary policy, Milton Friedman proposed that the money supply should grow at a constant rate (e.g., 3 to 5%) over time to match the increase in the demand for money as income grows.  But short-term (even day to day) fluctuations in money demand would have resulted in very volatile interest rates in order to keep money demand in line with the steadily increasing supply. Central banks around the world have generally targeted interest rates instead to allow short run adjustments in supply to short-run changes in demand. But setting and adjusting the policy interest rate can be tricky as well.

The ideal monetary regime is to fix the value of currency to something (such as gold, or a basket of currency as in the case of the IMF’s SDRs, or a small basket of widely traded commodities) and then allow the public to adjust the supply to match its changing demand for that fixed value. Such a system follows currency board rules. The central bank passively supplies or redeems its currency in response to the public’s demand at the fixed price. Such a system has been adopted by several countries as is described in detail in my book on the creation of the Central Bank of Bosnia and Herzegovina.  [“One Currency for Bosnia-Creating the Central Bank of Bosnia and Herzegovina”]

Even under the most favorable conditions of widespread use for payments, bitcoin would suffer the weakness of the Friedman rule. With no elasticity to its supply, a holder of bitcoin wanting to sell some would have to offer a price that another holder would be willing to accept and visa versa. Its value would remain volatile (though less so). It is hard to imagine bitcoin ever succeeding as a widely used currency. https://www.economist.com/finance-and-economics/2021/06/10/cryptocoins-are-proliferating-wildly-what-are-they-all-for?frsc=dg%7Ce
