IMF Warns Dollar Stablecoins May Trigger Currency Runs

The International Monetary Fund issued a working paper warning that dollar-denominated stablecoins carry a double-edged risk for global currency markets: while they can broaden access to foreign exchange for people in countries with limited banking infrastructure, they may also act as a coordination mechanism that accelerates capital flight when local currencies come under severe pressure.

The IMF's concern centers on the speed and ease with which retail holders can shift from a weakening local currency into a dollar stablecoin. In traditional currency crises, logistical friction — finding a bank, exchanging cash, or navigating capital controls — has historically slowed panic-driven outflows. Stablecoins remove much of that friction, potentially compressing a slow-moving currency run into a near-instantaneous event that overwhelms a central bank's ability to respond.

At the same time, the paper acknowledges a legitimate upside. In emerging and frontier markets where residents struggle to obtain dollar-denominated savings or conduct cross-border transactions, stablecoins offer a practical alternative to costly or inaccessible formal channels. That improved access could support economic activity and financial inclusion in normal times, even as it introduces new macro-financial vulnerabilities during crises.

The dual finding puts policymakers in a difficult position. Restricting stablecoin adoption to protect exchange-rate stability risks cutting off a growing segment of the population from useful financial tools, while permitting unchecked growth could amplify the severity of any future currency shock. The IMF's analysis suggests regulators will need frameworks that distinguish between everyday use cases and the systemic risks that emerge when market confidence collapses.
