Over on the message board we've been discussing the implications of central bank-issued digital currency, otherwise known as CBDC. One view is that a central bank digital currency would lead to increased financial instability, Bank of England governor Mark Carney being a vocal proponent of this idea. There are a lot of criticisms that can be leveled against central bank digital currency, but the Carney critique is the one that worries me the least. Let's see why.  First off, let's establish what we mean by digital currency. Imagine that a central bank has discovered a technology that allows it to create an exact digital replica of the banknote. Like banknotes, these digital tokens are anonymous and untraceable. To make use of them, people don't have to register for an account. Rather, the tokens are held independently on one's device, sort of like how paper money is held in one's wallet without requiring any sort of registration with the issuing central bank. T...

50 SEK banknote issued by the Riksbank in 1960 "Do we need an eKrona?" asks Stefan Ingves, the Governor of the Riksbank, Sweden's central bank. The Riksbank is probably the central bank that has advanced the furthest in discussions surrounding the introduction of a central bank-issued digital currency (CBDC)—a new form of risk-free digital money for use by the public. Canada , New Zealand , Australia , the ECB , and China are also dissecting the idea, with more central banks to come in 2018. Sweden is approaching the issue from a unique angle, says Ingves. It is the only country in the world showing a consistent decline in cash and coin usage. I've written about this interesting pattern here , here , and here . Below is a chart: Ingves floats two theories. Either the Swedish public no longer wants central bank money, or alternatively they do want central bank money but not the type that is "made of pieces of paper," preferring instead an as-yet non-existen...

Cross section of a banknote with a cotton paper core surrounded by two layers of polymer [ Source ]   Central bankers are at their most comfortable when engaging in technical debates over the finer points of monetary policy. But over the next few years they may be forced out of their comfort zone into a thorny philosophical debate over anonymity and financial censorship. They are poorly equipped for such a debate. When central bankers monopolized the issuance of banknotes in the 1800s and early 1900s, little did they know that a hundred years later anonymity would become an important public good . And because banknotes are the only generally-accepted way for law-abiding citizens to make uncensored anonymous payments, central bankers effectively became—by accident rather than design—the sole purveyors of these vital services.* Banknotes are anonymous because it is very difficult to link banknotes to identities, say by monitoring usage of notes via a note's serial number. As for ...

No, I'm not talking about sound money in the sense of having a stable value. I'm talking about money that is sound because it can survive natural disasters, human error, terrorist attacks, and invasions. Kermit Schoenholtz & Stephen Cecchetti , Tony Yates , and Michael Bordo & Andrew Levin ( pdf ) have all recently written about the idea of CBDC, or central bank digital currency, a new type of central bank-issued money for use by the public that may eventually displace banknotes and coin. Unlike private cryptocoins such as bitcoin, the value of CBDC would be fixed in nominal terms, so it would be very stable—much like a banknote.* It's interesting to read how these macroeconomists envision the design of a potential CBDC. According to Schoenholtz & Cecchetti, central banks would provide "universal, unlimited access to deposit accounts." For Yates this means offering "existing digital account services to a wider group of entities." As for Lev...

David Birch recently grumbled about people's sloppy use of the term legal tender , and I agree with him. As Birch points out, what many of us don't realize is that shopkeepers have every right to refuse to accept legal tender such as coins and notes. This is because legal tender laws only apply to debts, not to day-to-day transactions. If someone has borrowed some money from you, for instance, then legal tender laws dictate a certain set of media that you cannot refuse to accept to settle that debt. These laws have been designed to protect your debtor from a situation in which you demand payment in a rare medium of exchange, say dinosaur bones, effectively driving them into bankruptcy. Conversely, they also protect you the lender from being paid in an inconvenient settlement medium. In Canada, for instance, a five cent coin is legal tender, but only up to $5. If your debtor wants to pay off a $10,000 debt using a truckload of nickels, you can invoke legal tender laws and tell ...

I wrote a bunch of posts on bitcoin between 2012-2015, but they tailed off a bit in late 2015 and 2016 as my attention turned to other subjects, namely old fashioned banknotes and cash, a terrifically fertile topic. Because my bitcoin posts tended to get a lot of comments at the time, I thought it would be worthwhile to go back and review some of the predictions I made, both for my sake and that of my readers. My predictions tend to fall into three related buckets. Bitcoins will not become a generally-accepted medium of exchange Even mainstream organizations like the Fed might one day want to adopt bitcoin tech Bitcoin will fall to zero On the first front, I've consistently written that bitcoin won't become a generally-accepted medium of exchange because of its volatility. And this prediction has panned out, so far at least. No, bitcoin has not destroyed VISA, nor has it driven the share prices of remittance providers like Western Union to zero, nor has it been adopted by unban...

"One dollar bill," watercolour by Adam Lister ( source ) R3, a company specializing in distributed ledger technology, has just posted a paper I wrote for them entitled Fedcoin: A Central Bank-issued Cryptocurrency . And here is a nice write-up on the Fedcoin idea in American Banker , which unfortunately is behind their paywall . The paper is pretty wide-ranging, but one thing that's worth focusing on is the ability of Fedcoin to provide some of the same features as banknotes, in particular anonymity and censorship resistance . That a Fedcoin system can be designed to provide the same degree of privacy as cash runs counter to some of its early critics , who see in Fedcoin a coming financial panopticon . One really neat things about good ol' cash is that, like bitcoin, it is a decentralized network. The opposite of this is a centralized network, say something like the deposit banking system. In the banking system, storage of value is handled by the issuing bank throug...

Narayana Kocherlakota, formerly the head of the Federal Reserve Bank of Minneapolis and now a prolific economics blogger, penned a recent article on the abolition of cash. Kocherlakota makes the point that if you don't like government meddling in the proper functioning of free markets, then you shouldn't be a big fan of central bank-issued banknotes. For markets to clear, it may be occasionally necessary for nominal interest rates to fall well below zero. Cash sets a lower limit to interest rates, thus preventing this rebalancing from happening. I pretty much agree with Kocherlakota's framing of the point. In fact, it's an angle I've taken before, both here and in A Libertarian Case for Abolishing Cash . Yes, my libertarian and other free-marketer readers, you didn't misread that. There is a decent case for removing banknotes that is entirely consistent with libertarian principles. If you think usury laws are distortionary because they impose a ceiling on int...

The Bank of England recently announced that it will end a 300-year tradition of allowing employees to keep chequing accounts at the Bank. You can see an example of a cheque above, which is marked with the sort code 10-00-00. Traditionally, folks like you and me have only been able to get a piece of the central bank's balance sheet by holding banknotes. Central bank deposit accounts, which are far more convenient, have been limited to banks and other financial institutions. But the BoE provides a rare example of regular people, specifically employees, being permitted to directly own fully transferable central bank deposits, at least until recently. The BoE's termination of this seemingly archaic practice is especially interesting in the context of growing efforts to crack open central bank balance sheets to those who have traditionally been hived off from them. A concrete step in this direction is the Federal Reserve's overnight reverse repurchase facility, which allows mon...
