Circle publishes reserve information through a transparency process. USDC reserve holdings are disclosed weekly, with mint and burn flows, and a Big Four accounting firm provides monthly third-party assurance that reserve value is greater than the amount of USDC in circulation.
The latest reserve report covers balances as of Feb. 27, 2026. It reported 75,109,039,300 USDC in circulation and $75,176,561,300 in reserve assets at fair value, meaning reported reserve assets exceeded USDC in circulation by about $67.5 million at that reporting date.
| Reserve or Circulation Item | Amount as of Feb. 27, 2026 |
|---|
| USDC in circulation | 75,109,039,300 USDC |
| Fair value of reserve assets | $75,176,561,300 |
| Excess reserve assets over USDC in circulation | About $67.5 million |
The reserve report defined USDC in circulation as total USDC supply on approved blockchains minus tokens allowed but not issued, Access Denied Tokens, and Circle Gateway pending burns. That matters because exchange data, blockchain explorers, and issuer reports may treat total supply, circulating supply, and restricted balances differently.

The Circle Reserve Fund is a government money market fund, and other reserve assets are held in segregated accounts at regulated financial institutions. Those segregated accounts are unencumbered and held separately from Circle's general corporate funds.
USDC held in a Circle Mint account is not covered by FDIC, SIPC, FSCS, or similar deposit insurance. That does not mean reserves are absent, but it does mean users should not treat USDC like an insured bank deposit.
