Cryptocurrencies in emerging markets: A stablecoin solution?

Abstract

We rationalize cryptocurrency adoption in a small open economy model. We show that digital dollarization, where stablecoins pegged to the USD are used for transactions, can improve social welfare. In contrast, the adoption of volatile cryptocurrencies, such as El Salvador’s 2021 decision to make Bitcoin legal tender, results in welfare losses. This outcome aligns with the observed low take-up of Bitcoin as legal tender. The welfare benefits of digital dollarization increase with the magnitude of macroeconomic shocks, providing motivation for the growing use of stablecoins in emerging markets as a safeguard against high inflation and macroeconomic instability .
