Stablecoin supply stalls at $305B but payments jump 45%

Stablecoin supply barely moved in the first nine months of 2026, rising 0.4% to $305 billion, while payments made with the tokens climbed 45% to $482 billion and transaction count jumped 71% to 1.04 billion. Circle's third-quarter results show the same split: USDC's circulating supply ended September unchanged at $73.9 billion from a year earlier, even as on-chain transaction volume surged 49% to $13.9 trillion.

"Balances were flat, but usage continues to grow," CEO Jeremy Allaire said on the earnings call.

Why it matters

The divergence is a story about velocity, not stalled adoption. Standard Chartered estimates overall stablecoin turnover has doubled to around 30 transfers per token per month this year, with USDC's velocity climbing to roughly 80 from 45, while Tether's USDT sits near seven because it mostly serves as dollar savings in emerging markets. Payment providers report the same pattern. StraitsX's stablecoin card programs grew from about 66,000 daily transactions in January to 291,000 in October, and Circle Payments Network reached a $41.3 billion annualized volume rate at the end of September, more than 15 times its year-earlier level.

There is also a measurement caveat. Allium counted $97.9 trillion in raw on-chain transfers over the period, but only about 0.5% of that, the $482 billion, was actual payments to businesses and consumers. The Bank for International Settlements reached a similar conclusion in June, finding that treating every transfer as a standalone payment misclassifies almost six in 10 transfer events.

Market impact

Supply stalled because its main source of demand weakened. Trading volumes fell more than 50% this year, cutting the need for fresh issuance, and a token that pays no interest is costly to hold when three-month Treasury bills yield around 4.1%. The GENIUS Act, which bars issuers from paying interest to holders, takes effect in January 2027.

Analysts still frame the flatline as cyclical rather than structural. Standard Chartered pushed its $2 trillion stablecoin market forecast to 2030 from 2028, citing slower supply growth, but Geoff Kendrick, the bank's global head of digital assets research, argues past flat periods ended once crypto markets recovered. Agentic payments, one of the year's most hyped demand sources, added 68.3 million transactions in the third quarter worth just $3.7 million in total, about 5 cents each, reinforcing the pattern: usage multiplies, float doesn't.
