The total market capitalization of all stablecoins has hit a record high of $322 billion, eclipsing the foreign exchange reserves of 95 countries, including several developed countries.
Right now, their combined market capitalization is greater than the foreign exchange reserves of Poland, Thailand, Mexico and developed economies such as the UK, Canada and even the oil-exporting giant United Arab Emirates.
Essentially, the amount of dollars and other fiat currencies held by users outside traditional banking channels now exceeds the official foreign exchange reserves, a sovereign protection against external economic shocks, in most nations.
Stablecoins are tokenized versions of fiat currencies issued on the blockchain. Their values are pegged 1:1 to the US dollar or other currencies such as the euro, yen, Swiss franc and others. Their combined market capitalization has grown manifold in recent years, with the majority of activity concentrated in coins pegged to dollars, e.g. and USD Coin (USDC).
The growth is evidence of how quickly 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, have more foreign exchange reserves than the market value of stablecoins.
Double-edged sword
Stablecoins are widely used for cryptocurrency trading. They allow users to exit volatile tokens without converting back to fiat currencies. For DeFi protocols, they act as settlement layers, and for cross-border payments, they provide a faster and cheaper way to move money across borders while bypassing legacy banking channels.
“The use of stablecoins in cross-border payments has grown, especially in corridors where legacy correspondent banks are slow or expensive,” said a recently released report from the Bank of International Settlements. “Cross-border stable coin flows have grown significantly since 2022, with particularly pronounced activity in regions experiencing high inflation and exchange rate volatility.”
But the ease of moving money carries a risk.
Stablecoin transactions can trigger capital outflows, leaving already vulnerable countries with current account deficits exposed to fiat currency depreciation.
“Increases in stablecoin flows are associated with subsequent domestic currency depreciation, departures from covered interest parity and widening of 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 bypassing of capital controls and providing a relatively frictionless mechanism for EMDE residents to move savings into dollar-denominated instruments,” the bank added.
