TLDR
- Stablecoin market cap fell $7.7B in June 2026, the biggest monthly drop since Terra’s collapse in 2022
- Total market cap sits at around $312B, down about 3% from its May peak
- Transaction volume hit a record $1.79 trillion in June, up 63% from May
- USDC processed $1.21T in transfers despite having less than half of USDT’s circulating supply
- Tokenized Treasury funds grew to nearly $16B, suggesting some capital shifted toward yield-bearing products
The stablecoin market shrank in June 2026 for the first time in five months, but transaction activity told a very different story.
Stablecoin Market Shrinks $7.7 Billion in June, Biggest Drop Since Terra

Market capitalization fell $7.7 billion to around $312 billion, according to CoinDesk Data. That was a 2.39% monthly drop and the largest dollar decline since the Terra-Luna collapse in May 2022.
Despite the shrinking supply, on-chain activity surged. Visa’s Allium-powered dashboard recorded $1.79 trillion in adjusted transaction volume for June, up 63% from May and 125% from a year earlier.
USDC accounted for about $1.21 trillion of that volume. USDT handled roughly $576 billion, despite having a much larger circulating supply.
Supply Falls While Usage Climbs
Tether’s USDT slipped from around $190 billion in May to about $184 billion. USDC dropped from a March peak near $80 billion to around $74 billion. Both tokens continued trading close to their $1 peg.
Analysts say the decline does not mirror the 2022 Terra crisis. That event wiped out $33.9 billion, nearly one-fifth of the market, in a single quarter. The June 2026 drop was far smaller and did not involve a depeg.
Standard Chartered found stablecoin turnover running at roughly six times per month, about double the rate of two years ago. A smaller supply moving faster explains how volume records can be set while total market cap falls.
Visa’s data shows stablecoin velocity at 13.56 per quarter, compared to 1.65 for US M1 money. Each stablecoin dollar is working roughly eight times harder than a typical bank-account dollar.
Where Did the Money Go?
Some of the capital that left stablecoins appears to have moved into tokenized Treasury products. These funds offer yield, which standard payment stablecoins do not.
The GENIUS Act, signed in July 2025, prohibits issuers from paying yield on payment stablecoins. That rule makes holding idle balances in stablecoins less attractive.
Tokenized Treasury funds grew to nearly $16 billion by late July. Circle’s USYC stood near $3 billion and BlackRock’s BUIDL near $2.64 billion. Total tokenized asset capitalization rose 1.75% to $30.1 billion in June, even as stablecoin supply fell.
However, public data cannot confirm the full $7.7 billion moved directly into these products. Some capital may have returned to bank deposits or left crypto markets entirely.
Regulation Still in Progress
The GENIUS Act framework takes effect on January 18, 2027, or 120 days after regulators issue final rules. As of July 28, those rules were not yet complete.
A joint federal proposal would require stablecoin issuers to verify customer identities. Comments are due August 21, 2026. The FDIC also issued proposed reporting forms on July 17.
DefiLlama placed total stablecoin market cap at around $309.9 billion on July 28, down 0.79% over 30 days.
