According to Digital Asset, an International Monetary Fund (IMF) report indicates that when banks or official foreign-exchange markets are unable to fully meet dollar demand, dollar stablecoins can increase the availability of foreign currency, reduce transaction costs, and improve financial accessibility; however, when the gap between the official exchange rate and the market exchange rate widens, they may accelerate the flow of funds from the local currency into dollar-denominated assets and rapidly spread market anxiety during crises. Simulations show that in economies that rely solely on cash, the average probability of a crisis is 3.9%, rising to 7.4% after stablecoins become widespread; at the point of greatest exchange-rate deviation, household welfare falls by up to 6.3%. The report recommends that regulators consider macroprudential measures such as temporary transaction limits to address large-scale trading or panic selling.
