Stablecoin Supply Drops Over $14 Billion Amid Regulatory Shifts

Stablecoin supply experienced its largest drop since Terra's collapse in May 2022. The total stablecoin supply peaked at $322.121 billion in mid-May 2026 before dropping by over $14 billion in less than three months, with the heaviest blow coming in June when approximately $11.41 billion was wiped out. By August 2, 2026, the total stablecoin supply had fallen to around $307.561 billion.

Tether's $USDT and Circle's $USDC were the biggest losers, with Tether's supply dropping from roughly $189 billion in early May to about $183.216 billion by August 2, while Circle's $USDC dropped from a March peak near $80 billion to around $72.069 billion over the same stretch.

The decline is largely due to changes in investor behavior following the introduction of new regulations under the GENIUS Act and reinforced by the Office of the Comptroller of the Currency (OCC) earlier this year, which treats 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.
