Central Bank Digital Currencies

And the Social Nature of Money

You’ve probably heard some of the fuss around central bank digital currencies (CBDCs). This article is neither a fiery condemnation (that would be too easy) nor a technical explanation, nor anything in between. I will briefly explain what they are, describe their attractions and dangers, and then explore some seldom-discussed foundational questions.

What is a central bank currency—digital or otherwise? It is money issued by a central bank such as the Federal Reserve that either circulates as cash or is held in accounts at the central bank. Today, the only entities that have accounts at the Fed are banks and other financial institutions. Private citizens and businesses can’t open an account at the Fed. I tried, but they put me on hold.

Here is a simplified version of how it works, accurate enough for the present purpose. Acme Bank has reserves of $100 million at the Fed. During the course of the day, it makes loans and takes deposits. The loans end up as deposits in other banks. At the end of the day, all these transfers are “cleared,” meaning that if Acme lent a total of $20 million and received a total of $15 million, its account balance at the Fed would fall by $5 million, and other banks in the system would see their balance rise by a total of $5 million also.

I hope you didn’t tune out as soon as you saw numbers. Basically what is happening is that central bank money moves from one bank’s account to another to settle accounts with other banks.

Obviously, these bank reserves at the Fed do not take the form of piles of hundred-dollar bills. They are digital already. So what is new about CBDCs?

The novelty stems from the fact that the money you and I spend (with the exception of cash) is not central bank money at all. It exists only in the ledger of your commercial bank or other institution. If I Paypal you $1000, my Paypal balance and your Paypal balance change, but nothing happens in the central bank. Same is true if Alice, who banks at Acme, writes a $1000 check to Bob, who deposits it in XYZ Bank, and then Carol, who also banks at XYZ, writes a $1000 check to Dave who deposits it in Acme. These individuals’ account balances go up and down, but their banks are even with each other and the Fed is not involved at all.

A central bank digital currency essentially allows private individuals and businesses to have accounts at the central bank. It would function just like (and ultimately replace) cash, requiring no intermediary, no bank, no credit card company, and no transaction fee. If I buy a coffee at your cafe, an app or card reader sends a message to automatically credit your account and debit mine. The user experience would be the same as today, but there would be no fee and no lag time. Normally, paying by debit or credit card involves a 3% fee and a day or two for the funds to become available to the seller.

Attractions and Dangers of CBDCs

Now I’ll list some other benefits and advantages of CBDCs. You might notice that with a mere twist of the lens, many of these advantages take on an ominous hue. But let’s start with the positive:

  • As mentioned, CBDCs can remove what is essentially a 3% tax on most consumer-level transactions, allowing swift, frictionless transactions and transfers of money.
  • Unlike with physical cash, all CBDC transactions would have an electronic record, offering law enforcement a powerful weapon against money laundering, tax evasion, funding of terrorism, and other criminal activity.
  • The funds of criminals and terrorists could be instantly frozen, rendering them incapable of doing anything requiring money such as buying an airplane ticket, filling up at a gas station, paying their phone or utility bills, or hiring an attorney.
  • CBDCs are programmable, allowing authorities to limit purchases, payments, and income in whatever ways are socially beneficial. For example, all products could have a carbon score, and consumers could be limited in how much they are allowed to buy. Or, if rationing becomes necessary, authorities could impose a weekly limit on food purchases, gas purchases, and so on.
  • With programmable currency, citizens could be rewarded for good behavior: for eating right and exercising, for doing good deeds that are reported by others, for staying away from drugs, for staying indoors during a pandemic, and for taking the medications that health authorities recommend. Or they could be penalized for bad behavior.
  • Taxation and wealth redistribution could be automated. Universal basic income, welfare payments, stimulus payments, or racial reparations could be implemented algorithmically as long as CBDC accounts were firmly connected with individual’s identities, medical records, racial status, criminal histories, and so forth.

Basically, beyond facilitating transactions, CBDCs offer an unprecedented opportunity for social engineering. Assuming that those in control are beneficent and wise, this is surely a good thing. But if, as many of us now believe, our authorities are foolish, incompetent, corrupt, or are merely fallible human beings incapable of handling too much power, then CBDCs can easily become instruments of totalitarian oppression. They allow authorities:

  • To freeze the funds not only of terrorists and evil-doers, but dissidents, thought criminals, and scapegoated classes of people.
  • To program money so it can only go to approved vendors, corporations, information platforms, and so forth. Those that fail to toe the party line can be “demonetized,” with consequences far beyond what befalls the hapless YouTuber who utters heresies about Covid, Ukraine, climate change, etc.
  • Under the guise of rewarding good behavior and penalizing bad, to control every aspect of life so that it conforms to the interests of elite corporate and political institutions.
  • To nip in the bud any opposition political movement by demonetizing its leaders and activists, either with no explanation at all, or under flimsy pretexts that their victims would have no way to contest.

It boggles my mind that the public could accept such a momentous transfer of power to central authorities, with nary a whisper of democratic process. Something this significant should require explicit public approval in the form of a referendum, constitutional amendment, or the like, after long and considered public debate. Instead, elites discuss it as if it were an inevitability.
