USDC’s circulating supply has dropped from $73.3 billion at the end of June to roughly $71.8 billion as of August 6, a decline of approximately $1.5 billion in just over five weeks. About $1 billion of that evaporated in a single seven-day stretch during late July and early August, pointing to a concentrated wave of redemptions rather than a slow bleed.
The contraction comes at an interesting time for Circle, which just posted Q2 2026 earnings on August 5 showing $701 million in revenue. The stablecoin issuer is making more money than ever while its product literally shrinks.
Supply down, usage up
USDC’s circulating supply is still up 19% year-over-year compared to Q2 2025 levels. A $1.5 billion drawdown against a $73 billion base works out to roughly a 2% reduction.
USDC processed $14.8 trillion in on-chain transaction volume during Q2 2026, a 151% increase compared to the same quarter last year. That’s roughly equivalent to the annual GDP of the European Union moving through a single stablecoin’s rails in just three months.
