Stablecoin supply has fallen more than $14 billion since May 2026 after new federal rules stripped issuers of the ability to pay interest on their tokens. Tether's USDT and Circle's USDC account for most of the decline, even as transaction volume across stablecoin networks hit a record.
Total stablecoin supply peaked near $322.121 billion in mid-May 2026 before falling by more than $14 billion in less than three months. June delivered the heaviest blow, wiping out approximately $11.41 billion in a single month, the steepest monthly contraction since TerraUSD imploded in May 2022. By August 2, total supply had fallen to roughly $307.561 billion, and the sector shed another $2.767 billion in the past seven days, according to data from defillama.com.
Tether and Circle Lead the Retreat
Tether's USDT, the largest stablecoin, fell from roughly $189 billion in early May to about $183.216 billion by August 2. Circle's USDC dropped from a March peak near $80 billion to around $72.069 billion over the same stretch.
Together the two tokens account for most of the decline, though Sky's USDS and Ethena's USDe also posted double-digit percentage losses. Not every token lost ground: Global Dollar's USDG grew during the pullback, and several tokenized cash products kept gaining users even as the broader category contracted.
Washington Rules Cut Off the Yield Trade
The GENIUS Act, signed into law in July 2025, set the first federal framework for payment stablecoins and bars licensed issuers from paying interest or yield tied to holding their tokens. The Office of the Comptroller of the Currency reinforced that stance with proposed rules early in 2026, treating stablecoins as transaction tools rather than savings accounts.
As a result, investors who once parked idle cash in USDT or USDC to earn yield no longer have that option, and many have moved instead into tokenized Treasury and money-market products, which grew to the high teens of billions of dollars by late July. Falling crypto prices added to the pressure: Bitcoin and other major cryptocurrencies dropped significantly in value during the second quarter of 2026, cooling the trading activity that normally keeps demand for stablecoins high.
Transaction Volume Hits a Record Despite the Shrinking Float
Even as the total float shrank, activity on stablecoin networks hit a record, according to the Visa Onchain Analytics Dashboard, powered by Allium Labs. Adjusted transaction volume reached about $1.8 trillion in June 2026, up roughly 63% from the previous month.
USDC processed about $1.21 trillion of that volume despite carrying a smaller total supply than USDT, which processed about $576 billion. Over the past 30 days, stablecoins settled $5.2 trillion in onchain transactions across 1.6 billion transfers.
Analysts expect the pullback to stay contained rather than spread into a broader crisis like the 2022 collapse, which involved TerraUSD's failure and the bankruptcy of FTX. Stablecoin supply has more than doubled over the past several years despite the recent pullback. A similar-sized drop between December 2025 and February 2026 reversed within months as well.
