IMF Warns Dollar Stablecoins Could Heighten Currency Crisis Risks in Fixed Exchange Rate Economies

Research finds stablecoins may accelerate capital flight and increase pressure on overvalued currencies despite offering benefits during stable periods.

Dollar-pegged stablecoins could amplify the risk of currency crises in economies that maintain overvalued fixed exchange rates, according to a new research paper published by the International Monetary Fund (IMF).

The study argues that while stablecoins can enhance economic efficiency during periods of financial stability, they may significantly worsen currency pressures when exchange rate imbalances emerge.

Authored by IMF researcher Brandon Joel Tan, the paper finds that U.S. dollar-denominated stablecoins can accelerate capital flight by transforming fragmented parallel-market exchange rates into a transparent and widely accessible benchmark. This greater price transparency makes it easier for market participants to coordinate sales of local currencies during periods of financial stress.

The research concludes that stablecoins can improve economic welfare under stable macroeconomic conditions by facilitating transactions and expanding access to digital financial services.

However, when official exchange rates become significantly misaligned with market fundamentals, widespread use of stablecoins may intensify speculative pressure and accelerate the erosion of foreign exchange reserves, increasing the likelihood of a full-scale currency crisis.

The paper cites Bolivia as an illustrative case after authorities eased restrictions on virtual asset transactions in June 2024, highlighting how broader access to digital dollar-based assets could affect economies operating under exchange rate pressures.

According to the IMF's simulations, the average probability of a currency crisis rises from 3.9% in a cash-only economy to 7.4% in an economy that relies entirely on stablecoins.

Under conditions where exchange rate misalignments reach their highest levels, the probability increases even more sharply, from 4.8% to 12.9%, suggesting that widespread stablecoin adoption could more than double currency crisis risks in countries operating fixed exchange rate regimes.

The findings come as central banks around the world intensify scrutiny of the rapidly expanding stablecoin market.

Last month, the European Central Bank (ECB) warned European Union finance ministers that broader issuance of euro-denominated stablecoins could weaken banks' lending capacity and complicate the central bank's ability to manage monetary policy and steer interest rates.

The ECB's concerns were raised in response to proposals by the economic think tank Bruegel, which recommended easing liquidity requirements for stablecoin issuers to support the development of the euro-denominated stablecoin market. Despite such initiatives, the global stablecoin sector continues to be dominated by U.S. dollar-linked digital assets.

The IMF paper underscores the growing policy debate over stablecoins, suggesting that while the technology can improve payment systems and financial inclusion, regulators must carefully balance those benefits against the heightened financial stability risks that may emerge in economies with vulnerable exchange rate regimes.
