The combined market value of all stablecoins has hit a record high of $322 billion, dwarfing the foreign exchange reserves of 95 countries, including several developed countries.
As of now, their combined market cap is bigger than the FX reserves of Poland, Thailand, Mexico, and developed economies such as the United Kingdom, Canada and even the oil-exporting giant United Arab Emirates.
In essence, the amount of dollars and other fiat currencies held by users outside traditional banking channels now exceeds the official FX reserves, a sovereign protective cover against external economic shocks, of most nations.
Stablecoins are tokenized versions of fiat currencies issued on blockchain. Their values are pegged 1:1 to the U.S. dollar or other currencies such as the euro, yen, Swiss franc and others. Their combined market cap has grown multi-fold in recent years, with most activity concentrated in dollar-pegged coins such as tether USDT$0.9993 and USD Coin (USDC).
The growth is evidence of how fast capital is migrating to blockchain rails.
Foreign exchange (FX) reserves are the dollars, euros, yen, and gold that central banks hold as a buffer to stabilize their currencies, pay foreign debts, and finance energy and other imports. Only 14 nations, led by China, Japan, Russia, India, Taiwan and Germany, hold more FX reserves than the market value of stablecoins.
Double-edged sword
Stablecoins are widely used for trading cryptocurrencies. They allow users to exit volatile tokens without converting back to fiat currencies. For DeFi protocols, they serve as the settlement layer, and for cross-border payments, they provide a faster, cheaper way to move money across borders while bypassing legacy banking channels.
"The use of stablecoins in cross-border payments has grown, notably in corridors where legacy correspondent banking is slow or costly," a recently released Bank of International Settlements report said. "Cross-border stablecoin flows have grown substantially since 2022, with particularly pronounced activity in regions experiencing high inflation and exchange rate volatility."
But the ease of moving money comes with a risk.
Stablecoin transactions can trigger capital outflows, leaving already vulnerable current account deficit countries exposed to fiat-currency depreciation.
"Increases in stablecoin flows are associated with subsequent domestic currency depreciation, deviations from covered interest parity and widening wedges between stablecoin-implied and official exchange rates in segmented markets (Aldasoro et al (2026))," the BIS said.
"These patterns are consistent with stablecoins enabling circumvention of capital controls and providing a relatively frictionless mechanism for EMDE residents to shift savings into dollar-denominated instruments," the bank added.
