Circle is the issuer of USDC, the second-largest payment stablecoin globally and the canonical reference instrument for the regulated-non-bank dollar-stablecoin design. Founded in 2013, the company operates from New York and supervises USDC issuance under a combination of US state money-transmitter and trust-charter wrappers, and is positioned to slot into the federal-non-bank issuer route under the US GENIUS Act permitted-payment-stablecoin perimeter. USDC reserves are canonically held in cash deposits at insured depository institutions and short-dated US Treasury bills, with monthly attestation and a public reserve disclosure cadence widely used by counterparties as the operational reference point. For a tokenisation operator, Circle is the worked example of how a non-bank dollar issuer holds a regulated perimeter together while distributing across exchanges, DeFi venues, and bank-grade settlement counterparties simultaneously.
What they do
Circle's business is issuance, redemption, and reserve management for USDC and a smaller euro-denominated counterpart (EURC). Primary mint and redeem run through a permissioned set of institutional counterparties (exchanges, custodians, market-makers, bank treasuries), with on-chain transferability broader than the direct-redemption set. The architectural shape is similar to a money-market fund's primary-versus-secondary distinction: a small group of authorised participants face the issuer for cash-versus-token swaps, and the secondary on-chain market clears against that group. The company also operates Circle Mint as the institutional issuance gateway and programmable-payments APIs for embedded use cases.
USDC's structural distinguishing feature against other major stablecoins is the reserve discipline. The reserve is composed of cash and short-dated US Treasuries, held with custodians including BNY, with monthly reserve attestation by a major audit firm. The instrument has been tested at scale through multiple market episodes, including a brief depeg in March 2023 tied to exposure at Silicon Valley Bank, and recovered without redemption gating. That stress experience is part of why USDC is the default institutional-treasury-comfortable stablecoin in the US and why the GENIUS Act perimeter was substantially designed around an instrument of this shape.
Programme participation
- Securitize / BlackRock BUIDL. A Circle smart contract sits adjacent to the BUIDL share class and atomically swaps BUIDL for USDC during market hours, giving BUIDL holders an on-chain liquidity primitive that does not require waiting for the off-chain fund-redemption cycle.
- Cross-border payments. USDC is the most-cited non-bank settlement asset across crypto-native cross-border corridors, and is increasingly visible in regulated remittance and B2B-payment use cases against bank counterparties.
- DeFi venue distribution. USDC is the dominant stablecoin pair across major decentralised exchanges and lending venues, including the Centrifuge-Aave Horizon RWA-DeFi rails.
- EURC. Euro-denominated counterpart issued under MiCA Title IV (EMT) authorisation, distributed through a similar institutional-counterparty model.
- OCC trust-bank charter. Circle is among the firms with conditional approval from the OCC under the trust-bank charter pathway, aligning the issuer with the GENIUS Act federal-non-bank route.
Regulatory positioning
Circle holds NYDFS trust-charter arrangements through Circle Internet Financial and a patchwork of state money-transmitter licences across the US, plus Circle Mint regulatory permissions in the relevant overseas jurisdictions for institutional distribution. Under the GENIUS Act, Circle is positioned to operate under the federal-non-bank permitted issuer route, with the OCC as supervising regulator. The company's conditional OCC trust-bank approval (granted as part of the 2025-2026 chartering wave) is the operational pathway into that perimeter; final approval would put Circle under unified federal supervision in place of the state-by-state regime.
For the EU market, Circle holds an electronic-money-institution (EMI) authorisation in France that supports EURC issuance under MiCA Title IV. That dual-jurisdictional licensing posture (federal-leaning US, EMI in the EU) gives Circle one of the cleanest cross-Atlantic regulated footprints of any stablecoin issuer.
USDC is structurally outside the tokenised deposits frame. The instrument is a non-bank claim on Circle, backed by segregated reserves, with the holder exposed to the reserve composition and the segregation arrangements rather than to a bank balance sheet. That distinction is the load-bearing one between regulated payment stablecoins and tokenised deposit instruments, and the perimeter line the GENIUS Act formalised for the US market.

- Circle has been publicly reported as having pursued a public-listing pathway. Treat any specific listing-status claim as requiring verification against current disclosure rather than asserting the fact off this page.
- Ongoing. USDC continues as the secondary-market settlement pair adjacent to BlackRock's BUIDL on the Securitize platform.
