The total market capitalization of stablecoins has reached a new all-time high of $322 billion, surpassing the foreign exchange reserves of 95 countries.

As of May 26, a Coindesk report shows the total global stablecoin market capitalization has crossed $322 billion, reaching an all-time high. This size exceeds the official foreign exchange reserves of emerging economies like Poland, Thailand, and Mexico, as well as developed economies including the U.K., Canada, and the United Arab Emirates. Currently, only 14 economies—such as China, Japan, Russia, India, Taiwan, and Germany—hold foreign exchange reserves larger than the total stablecoin market cap. Stablecoins have become a core pricing and settlement medium for cryptocurrency asset trading, letting users hedge against crypto price volatility without frequent conversions to fiat currency. In decentralized finance (DeFi) protocols, stablecoins serve as a fundamental settlement tool; in cross-border payments, their low cost and high efficiency make them a viable alternative for remittances in areas where traditional banking channels are inadequate or too expensive. A recent Bank for International Settlements (BIS) report notes that since 2022, stablecoin cross-border flows have increased significantly—especially in regions with high inflation and severe exchange rate fluctuations. However, improved fund transfer efficiency also brings potential risks. Stablecoin transactions may intensify capital outflow pressure, leaving emerging markets already facing current account deficits more vulnerable to currency depreciation shocks. BIS research further points out that growth in stablecoin liquidity is strongly correlated with subsequent currency devaluation, deviations from covered interest rate parity, and widening gaps between stablecoin implied exchange rates in fragmented markets and official exchange rates. These phenomena suggest that stablecoins may act as a technical channel to bypass capital controls, allowing residents of emerging markets and developing economies (EMDEs) to convert savings into dollar-denominated assets with low friction, posing a challenge to the effectiveness of sovereign monetary policies.
