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.
Stablecoins and Crypto Shocks

In a previous post, we described the rapid growth of the stablecoin market over the past few years and then discussed the TerraUSD stablecoin run of May 2022. The TerraUSD run, however, is not the only episode of instability experienced by a stablecoin. Other noteworthy incidents include the June 2021 run on IRON and, more recently, the de-pegging of USD Coin’s secondary market price from $1.00 to $0.88 upon the failure of Silicon Valley Bank in March 2023. In this post, based on our recent staff report, we consider the following questions: Do stablecoin investors react to broad-based shocks in the crypto asset industry? Do the investors run from the entire stablecoin industry, or do they engage in a flight to safer stablecoins? We conclude with some high-level discussion points on potential regulations of stablecoins.
