According to Digital Asset, an International Monetary Fund (IMF) report says that when banks or official foreign-exchange markets cannot sufficiently meet demand for dollars, dollar stablecoins can increase access to foreign currency, lower transaction costs, and improve financial inclusion; but when the gap between official exchange rates and market rates widens, they may accelerate capital flowing from local currency into dollar-denominated assets and quickly spread market anxiety during crises. Simulations show that in economies that use only cash, the average probability of a crisis is 3.9%, which rises to 7.4% after stablecoin adoption; when exchange-rate deviations are at their maximum, household welfare declines by as much as 6.3%. The report recommends that regulators consider macroprudential measures such as temporary transaction limits to address large-scale transactions or panic selloffs.
