Stablecoin Supply Falls $15B, Biggest Decline Since Terra

Total stablecoin supply peaked near $322.121 billion in mid‑May 2026 and declined to about $307.561 billion by Aug. 2, a drop of roughly $14.56 billion over less than three months. June recorded the largest monthly outflow, with about $11.41 billion leaving the sector, and the past seven days showed an additional $2.767 billion withdrawn.

The contraction concentrated in the largest tokens. Tether’s USDT fell from roughly $189 billion in early May to about $183.216 billion by Aug. 2. Circle’s USDC dropped from a March peak near $80 billion to about $72.069 billion over the same period. Smaller issuers such as Sky’s USDS and Ethena’s USDe posted double‑digit percentage declines. Global Dollar (USDG) and several tokenized cash products gained supply during the period.

Federal rules that took effect after the GENIUS Act was passed in July 2025 barred licensed payment stablecoin issuers from paying interest or yield tied to holding or using their tokens. Guidance issued by bank regulators in early 2026 treated payment stablecoins as instruments for transactions rather than interest‑bearing products, removing a yield incentive for holders to keep cash parked in stablecoins.

Capital that left stablecoins flowed into tokenized U.S. Treasuries and money‑market products. Tokenized Treasuries approached $17 billion, and broader tokenized real‑world asset holdings reached about $32 billion on some measures. Several tokenized cash products reported net inflows over the same period.

Cryptocurrency price declines in the second quarter of 2026 reduced trading volumes that typically support stablecoin demand as trading collateral. New rules in Europe under Markets in Crypto‑Assets also restricted certain noncompliant tokens on exchanges, contributing to outflows in that region.

On‑chain activity remained elevated. A payments network on‑chain analytics dashboard showed adjusted transaction volume near $1.8 trillion in June 2026, up about 63% month‑over‑month. USDC accounted for approximately $1.21 trillion of that volume and USDT about $576 billion. After filtering non‑economic activity, adjusted volume was near $1.3 trillion across 214.1 million transactions; retail‑sized transfers represented $7.1 billion and 144.6 million transfers.

Stablecoin issuers are shifting revenue models as interest income on reserves declines. Revenue is increasingly coming from transaction fees, distribution agreements and compliance services. USDC gained share in trading volume relative to its supply, and card networks reported rising stablecoin settlement activity, reflecting greater use of tokens for moving funds rather than holding them.

Stablecoin supply had more than doubled over several years before the recent pullback. A prior decline between December 2025 and February 2026 reversed within months, based on available market data.
