The Bank for International Settlements published a warning on the stablecoin market in its 2026 Annual Economic Report. The BIS, which serves as a bank for central banks, stated that stablecoins borrow blockchain technology conveniences without the institutional foundations that make money trustworthy, and scaling them up in their current form could import fresh risks. The assessment addresses a market worth roughly $320 billion as of end-May 2026, with 99.4% of fiat-backed stablecoins by market value pegged to the dollar and concentrated in two tokens: USDT and USDC. The report arrives as the White House pushes to pass the CLARITY Act, a crypto market-structure bill with a July 4 target.
BIS Report Identifies Stablecoin Market Concentration and Design Flaws
The report stated that stablecoin growth is concentrated in two U.S. dollar-pegged tokens, Tether's USDT and Circle's USDC, the two largest by market capitalization. They sit well above the next tier of coins, including Sky's USDS, BitGo's USD1 and Ethena's USDE. This concentration makes 99.4% of fiat-backed stablecoins by market value pegged to the dollar in a market worth roughly $320 billion as of end-May 2026.
With secondary-market prices that drift from a dollar and common redemption frictions, the report stated that current designs resemble exchange-traded fund shares more than a usable means of payment. Because stablecoins circulate on public, permissionless blockchains where pseudonymous wallets blunt anti-money-laundering checks, the BIS stated they account for a significant share of illicit on-chain activity.
The report also identified a risk that a wave of redemptions could force fire sales of the Treasury bills backing many of these stablecoins, potentially transmitting stress to money markets and the broader market for sovereign debt.
BIS Warns of Dollarization Threat to Emerging Economies
The report delivered its sharpest warning for emerging economies. The BIS cautioned that demand for dollar stablecoins could mirror classic dollarization, allowing households to bypass capital controls, reshape cross-border flows, and erode monetary sovereignty. The BIS noted that like past episodes, such a shift could prove difficult to reverse.
BIS Recommends Tokenized Money Anchored in Central Bank Reserves
The BIS stated it does not call for a ban. Instead the report recommended fixing stablecoin weaknesses while integrating blockchain technology into the existing banking system, with tokenized money anchored in central bank reserves.
Stablecoins remain politically contested as the White House pushes to pass the CLARITY Act, the broader crypto market-structure bill, by a July 4 target. Among its sticking points is a provision on stablecoin yield, which is returns paid to holders for keeping funds in stablecoins. It resembles bank-deposit interest, typically generated through lending, staking, or reserve earnings.
