What is USDC?
USDC is a stablecoin issued by Circle, a US company listed on the New York Stock Exchange, and designed to be redeemable one-for-one for US dollars. Its reserves are held in cash at banks and in a government money market fund that invests in short-term Treasuries and repo agreements. People use it for trading, payments, DeFi and moving dollars across borders.

How USDC works
Approved business customers send dollars to Circle and receive newly minted USDC; when they send USDC back, Circle pays out dollars and destroys the tokens. Everyday users usually buy and sell USDC on exchanges or in apps. Because large customers can always redeem at $1 with Circle, traders have a reason to close any gap between the market price and a dollar.
Circle holds reserves separately from its own operating money. Part sits as cash at banks, and the rest is in the Circle Reserve Fund, a government money market fund managed by BlackRock that holds short-dated Treasuries and overnight repurchase agreements. Circle discloses holdings weekly and publishes monthly assurance reports from an independent accounting firm. That design keeps most backing in very short-term, government-linked assets, though some cash still sits at commercial banks.
USDC exists natively on many blockchains, and Circle runs a transfer protocol to move it between them without wrapped copies. Circle can freeze USDC at specific addresses under its terms, for example at law-enforcement request. In July 2026 the OCC granted final approval for Circle's national trust bank, which positions the company for federal oversight as the GENIUS Act's licensing rules are finalized.
Key moments
- 2018Circle launches USDC and begins publishing reserve reports.
- 2023USDC briefly drops below 87 cents after Silicon Valley Bank fails with $3.3 billion of reserves inside; it recovers once deposits are protected.
- 2025Circle lists on the NYSE in June; the GENIUS Act becomes law in July; the OCC conditionally approves Circle's trust bank in December.
- 2026The OCC gives final approval to First National Digital Currency Bank, N.A. on July 10.
Supply
USDC has no supply cap. Tokens are minted when customers deposit dollars and burned when they redeem, so supply tracks demand. Circle earns interest on the reserves; holders receive no yield from Circle directly.
Risks to understand
- Banking and custody risk: the 2023 depeg showed that trouble at a bank holding reserves can shake confidence even if losses are eventually covered.
- Freeze risk: Circle can block USDC at addresses under its terms, so tokens linked to flagged activity can become unusable.
- Regulatory transition: The GENIUS Act, signed in July 2025, is expected to take effect on January 18, 2027. As of October 2026, Treasury, the OCC and the Federal Reserve had published proposed implementing rules, but final rules were still pending.
- Redemption access: direct redemption is for approved business accounts; most individuals rely on exchanges to convert USDC to dollars.
