In our recent primer on Crypto-assets and Decentralized Finance (DeFi), we explained that, so long as crypto-assets remain confined to their own world, they pose little if any threat to the traditional finance (TradFi) system. Yet, some crypto-assets are being used to facilitate transactions, as collateral for loans, as the denomination for mortgages, as a basis for risk-sharing, and as assets in retirement plans. Moreover, many financial and nonfinancial businesses are seeking ways to expand the uses of these new instruments. So, it is easy to imagine how the crypto/DeFi world could infect the traditional financial system, diminishing its ability to support real economic activity.
In this post, we highlight how the key problems facing TradFi (ranging from fraud and abuse to runs, panics, and operational failure) also plague the crypto/DeFi world. We also examine the different ways in which TradFi and crypto/DeFi address these common challenges.
To summarize our conclusions, while the solutions employed in TradFi are often inadequate and incomplete, features such as counterparty identification and centralized verification make them both more complete and more effective than those currently in place in the world of crypto/DeFi. Ironically, addressing the severe deficiencies in the current crypto/DeFi infrastructure may prove difficult without making highly unpopular changes that make it look more like TradFi—like requiring participants to verify their identity (see, for example, Makarov and Schoar and Crenshaw).
This is the second in our series of posts on crypto-assets and DeFi. In the next one, we will examine regulatory approaches to limit the risks posed by crypto/DeFi while supporting the benefits of financial innovation….
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....
