Digital currency is all the rage. Bitcoin has more than one thousand crypto cousins. There is even a token called dentacoin, whose issuers claim it will transform dentistry! In the past, we have been clear in our views. We agree with BIS General Manager Agustín Carstens: these are exactly like past attempts of people to issue their own private money. As Carstens said on another occasion, these tokens are “a combination of a bubble, a Ponzi scheme and an environmental disaster.”
Regardless of whether the blockchain will revolutionize dental health, the appearance of cryptocurrencies has driven central banks to think about one particular aspect of their business: paper currency issuance.
In this post, we expand on some aspects of our earlier discussion of central bank digital currency (CBDC). What is it and what would its wider introduction mean for the financial system? Our conclusion is unambiguous: Watch out what you wish for! ….
People have been saying for years that cash will disappear. So far, they have been spectacularly wrong. Over the past decade, the face value of U.S. dollar paper currency in public hands has doubled. Today, there is nearly $1.6 trillion in banknotes outstanding, more than 80 percent of which is in $100 bills (see chart)! In fact, there are thirty-nine $100 bills in circulation for each of the 326 million residents of the United States.
Why is 90 percent of the U.S. increase in circulation accounted for by $100 bills? One possible explanation is that, with nominal interest rates near zero, the opportunity cost of holding cash has dwindled, reducing the incentive to deposit rising inventories of cash in a bank. The second, and more compelling, reason for the big increase in large-denomination notes is more troubling: it facilitates illicit activity. Money laundering, tax evasion, drug dealing, human trafficking, and a whole host of other criminal activities run on cash. Big banknotes are a convenient way to transfer funds anonymously with finality. A $100 bill weighs less than a gram, so $1,000,000 weighs roughly 10kg and is small enough to fit in a medium-size briefcase.
To put it simply, most of the U.S. currency in circulation is almost surely being used by criminals....
