Stablecoins and Crypto Shocks: An Update

Stablecoins are crypto assets whose value is pegged to that of a fiat currency, usually the U.S. dollar. In our first Liberty Street Economics post, we described the rapid growth of stablecoins, the different types of stablecoin arrangements, and the May 2022 run on TerraUSD, the fourth largest stablecoin at the time. In a subsequent post, we estimated the impact of large declines in the price of bitcoin on cumulative net flows into stablecoins and showed the existence of flight-to-safety dynamics similar to those observed in money market mutual funds during periods of stress. In this post, we document the growth of stablecoins since 2019, including the evolution of the reported collateral backing major stablecoins. Then, we estimate the impact on the stablecoin industry of large bitcoin price increases that occurred between 2021 and 2025.
Is There a Bitcoin–Macro Disconnect?

Cryptocurrencies’ market capitalization has grown rapidly in recent years. This blog post analyzes the role of macro factors as possible drivers of cryptocurrency prices. We take a high-frequency perspective, and we focus on Bitcoin since its market capitalization dwarfs that of all other cryptocurrencies combined. The key finding is that, unlike other asset classes, Bitcoin has not responded significantly to U.S. macro and monetary policy news. This disconnect is puzzling, as unexpected changes in discount rates should, in principle, affect the price of Bitcoin.
Bitcoin Is Not a New Type of Money

Bitcoin, and more generally, cryptocurrencies, are often described as a new type of money. In this post, we argue that this is a misconception. Bitcoin may be money, but it is not a new type of money. To see what is truly new about Bitcoin, it is useful to make a distinction between “money,” the asset that is being exchanged, and the “exchange mechanism,” that is, the method or process through which the asset is transferred. Doing so reveals that monies with properties similar to Bitcoin have existed for centuries. However, the ability to make electronic exchanges without a trusted party—a defining characteristic of Bitcoin—is radically new. Bitcoin is not a new class of money, it is a new type of exchange mechanism, and this type of exchange mechanism can support a variety of forms of money as well as other types of assets.
