Stablecoin supply shrinks $14B from May peak as turnover hits record pace

Stablecoin supply has contracted by $14 billion from its May peak, yet settlement volumes are hitting records — signaling a shift from idle dollars to active payments.

The stablecoin market has shed about $14 billion in value since May, the sharpest monthly contraction since 2022, even as on-chain settlement volumes reached a record $1.79 trillion in June.

"Stablecoin turnover now occurs approximately six times monthly, roughly double the frequency observed two years prior," Standard Chartered research shows.

Tether's USDT supply declined by $5.5 billion to about $184 billion, while Circle's USDC contracted to approximately $74 billion from a March high near $80 billion, according to CoinDesk data. Both assets maintained their dollar peg throughout the period. USDC facilitated $1.21 trillion in June transfers despite holding less than half of USDT's circulating supply, Visa's Allium-powered analytics platform shows.

The divergence suggests stablecoins are evolving into a faster-moving payments network rather than a repository for idle digital dollars. Visa's data shows stablecoin velocity at 13.56 per quarter, compared with 1.65 for traditional US M1 money supply — meaning each stablecoin dollar circulates about eight times faster than conventional bank-held currency.

Capital Migration and Tokenized Treasuries

A portion of the capital exiting stablecoins appears to have flowed into tokenized Treasury products, which reached nearly $16 billion in late July. Circle's USYC approached $3 billion, while BlackRock's BUIDL stood at approximately $2.64 billion. The GENIUS Act, enacted in July 2025, prohibits payment stablecoin issuers from distributing yield, reducing the incentive to hold idle stablecoin balances.

Regulatory Timeline

The GENIUS Act framework becomes enforceable on Jan. 18, 2027, or 120 days after final rule publication. Implementing regulations remain incomplete as of July 28. A collaborative federal proposal would mandate customer identity verification for stablecoin issuers, with a public comment period closing Aug. 21. The FDIC separately released proposed reporting requirements on July 17.
