Circle

Institution · Stablecoin issuer

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, where 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.
  • Circle Payments Network + Nium last-mile payouts (live, May 2026). Nium joined the Circle Payments Network as a global payout partner, giving institutions a single integration to route USDC-settled payments into Nium's last-mile payout rails across 190-plus countries; the connection carried USD 8.3 billion in annualised transaction volume on trailing-30-day activity as of 31 March 2026 (Circle press release).
  • Thunes convert-on-payout via Swift (live, March 2026). Thunes holds funds in USDC until disbursement, then converts and settles locally across its 130-plus country payout network. In March 2026 Thunes opened this Pay-to-Stablecoin-Wallets rail to 11,500 Swift-connected banks with no additional integration required (Thunes).
  • Standard Chartered integrated minting and redemption (live, July 2026). Standard Chartered launched integrated USDC minting and redemption inside its existing client onboarding, the first global systemically important bank (G-SIB) to offer the service natively rather than routing clients to a separate Circle account (Circle press release).
  • Circle Gateway unified USDC balance (live, July 2026). Gateway gives an integrator a single USDC balance spendable across the 12 supported chains (as of June 2026: Arbitrum, Avalanche, Base, Ethereum, HyperEVM, Optimism, Polygon PoS, Sei, Solana, Sonic, Unichain, and World Chain), replacing pre-positioned per-chain inventory as the way multi-chain settlement stays instant (Circle blog).
  • DeFi venue distribution. USDC is the dominant stablecoin pair across major decentralised exchanges and lending venues, including the Centrifuge-Aave Horizon RWA (real-world asset)-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 sits 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.

Recent activity

  • 22 Jul 2026Circle published a Relay case study as the production reference for Circle Gateway's unified-balance model. Relay, cross-chain payments infrastructure that has processed more than $40 billion in cross-chain volume and 186 million transactions across 85 blockchains since launching in 2024, replaced per-chain USDC inventory with a single Gateway balance spendable across the 12 Gateway-supported chains, replenishing a drained destination chain in under 500 milliseconds instead of waiting on a rebalance; roughly $410 million of Relay user volume settled via Gateway from March through June 2026. The design removes the pre-positioned per-chain float that multi-chain settlement builds have treated as a fixed capital cost.
  • 2 Jul 2026Standard Chartered and Circle launched integrated USDC minting and redemption inside the bank's existing client onboarding, the first G-SIB to offer the service natively (Circle press release).
  • 29 Jun 2026BNY expanded its stablecoin relationship with Circle, making USDC the first stablecoin on BNY's Digital Asset Custody platform with direct institutional mint and burn against BNY-held custody wallets. Notably, Circle is not among the 140-plus initial partners in Open USD, the shared-governance, revenue-sharing stablecoin consortium announced the following day (30 Jun 2026) by Visa, Stripe, Mastercard, BlackRock, and others; Open USD is structured as a direct economic challenger to the single-issuer reserve-yield model USDC represents.
  • May 2026Nium joined the Circle Payments Network as a global payout partner, extending USDC-settled payments into Nium's last-mile payout rails across 190-plus countries (Circle press release).
  • Mar 2026Thunes opened its USDC convert-on-payout rail to 11,500 Swift-connected banks (Thunes).
  • 2025-2026. OCC trust-bank charter conditional approval as part of the broader 2025-2026 chartering wave that also covered Ripple, BitGo, Fidelity Digital Assets, and Paxos.
    1. 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.
