The combined market value of all stablecoins has reached an all-time high of $322 billion, eclipsing the foreign exchange reserves of 95 countries, including several developed countries.
Currently, their combined market capitalization is greater than the foreign exchange reserves of Poland, Thailand, Mexico and developed economies like the United Kingdom, 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 blanket of sovereign protection against external economic shocks, of most countries.
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 several-fold over the past few years, with most of their activity focused on dollar-pegged coins such as Tether. and USD coin (USDC).
This growth is a testament to how quickly capital is migrating onto the 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 countries, led by China, Japan, Russia, India, Taiwan and Germany, hold more foreign exchange reserves than the market value of stablecoins.
Double-edged sword
Stablecoins are widely used to trade cryptocurrencies. They allow users to exit volatile tokens without converting back to fiat currencies. For DeFi protocols, they serve as a settlement layer and for cross-border payments, they provide a faster and cheaper way to move money across borders while bypassing traditional banking channels.
“The use of stablecoins in cross-border payments has grown, particularly in corridors where traditional correspondent banking is slow or expensive,” says a recently released report by the Bank for International Settlements. “Cross-border stablecoin flows have increased significantly since 2022, with activity particularly pronounced in regions experiencing high inflation and exchange rate volatility.”
But the ease of transferring money comes with risk.
Stablecoin transactions can trigger capital outflows, leaving already vulnerable and current account deficit countries exposed to fiat currency depreciation.
“Increased stablecoin flows are associated with subsequent depreciation of the national currency, deviations from covered interest parity, and widening spreads between implied and official stablecoin exchange rates in segmented markets (Aldasoro et al (2026)),” the BIS said.
“These models are consistent with stablecoins circumventing capital controls and providing a relatively smooth mechanism for EMDE residents to transfer their savings to dollar-denominated instruments,” the bank added.
