A new study by the International Monetary Fund has found that the growing prevalence of stablecoins pegged to the US dollar creates systemic risks for countries with fixed exchange rates. By simplifying access to dollar liquidity, these digital assets can accelerate the development of currency crises, undermining central banks' ability to maintain stability.
Vulnerability Mechanism
IMF economists note that in times of economic uncertainty, stablecoins allow the public and businesses to instantly convert national currency into digital dollar assets. This puts additional pressure on central bank reserves, as a mass outflow of funds increases demand for foreign currency and makes it harder to maintain a fixed exchange rate. Modeling shows: the higher the penetration of stablecoins into the economy, the faster panic spreads and the more likely a sharp market shift into dollar assets becomes, even with minor external shocks.
Catalyst, Not Cause
It is important to emphasize that stablecoins themselves are not the root cause of financial instability. However, they act as a powerful catalyst, exposing and exacerbating existing macroeconomic imbalances. The greatest risks are concentrated in countries with low trust in the national currency, weak monetary policy, and a rigid exchange rate peg. Under such conditions, stablecoins become a tool for accelerated capital flight, which can trigger a crisis even in a relatively stable external environment.
Regulatory Challenges
The IMF urges regulators to consider the growing role of stablecoins when developing measures to ensure financial stability. In December 2025, experts already warned about the risks of losing control over capital movements in countries with high inflation. Against the backdrop of a record global turnover of stablecoins, which reached $1.79 trillion in June, these warnings are becoming particularly relevant.
Expert Commentary: This analysis confirms my long-standing position: stablecoins are not a neutral tool for economies with fixed exchange rates. They act as a "digital accelerator" for fundamental problems, and ignoring this factor could cost countries their currency sovereignty. Regulators urgently need to adapt their stress-testing models to include scenarios of a mass shift into stablecoins.
