Circle’s euro-backed stablecoin, EURC, has surpassed €400 million in circulation, reinforcing its position as the largest euro-denominated stablecoin as demand for regulated digital assets continues to grow across Europe.

The milestone, announced on Aug. 17, 2026, marks fivefold growth in EURC’s circulation over the past year. Circle said the expansion has been supported by wider blockchain availability, increasing institutional participation and the regulatory clarity introduced by the European Union’s Markets in Crypto-Assets, or MiCA, framework.

EURC Accounts for More Than Half of the Euro Stablecoin Market

EURC now represents more than half of the euro stablecoin market, which had grown to roughly €650 million by mid-2026, according to DeFiLlama data cited in the announcement. EURC’s market capitalization was approximately $443 million. The remaining euro-denominated supply is spread across smaller issuers, including EUR CoinVertible, a token issued by Société Générale’s digital-asset subsidiary SG-Forge. For scale, dollar-denominated assets such as Tether’s USDT and Circle’s own USDC account for the overwhelming majority of global stablecoin circulation, leaving euro tokens a small fraction of the wider market.

The stablecoin has also gained from trading activity across major cryptocurrency exchanges, including Coinbase, Kraken and Bitstamp. The availability of EURC trading pairs has helped improve liquidity between euro and dollar markets while making the asset more accessible to users and institutions.

Circle, which launched its flagship dollar stablecoin USDC in 2018, first issued EURC on Ethereum in 2022 and later expanded it to additional blockchain networks. Avalanche, Stellar, Solana and Base were among the ecosystems added as Circle sought exposure to networks with strong developer activity, liquidity and decentralized finance usage.

By the end of 2024, EURC circulation had reached about €80 million. Its later acceleration coincided with the implementation of MiCA, which established regulatory requirements covering reserve assets, governance and redemption rights for eligible stablecoin issuers. MiCA’s stablecoin provisions began applying across the EU in mid-2024, and Circle had registered as an electronic money institution in France in 2023, ahead of the new regime taking effect.

MiCA Supports Institutional Adoption

The regulatory framework has become an important factor in the development of euro-denominated stablecoins. For institutions and enterprises, clearly defined requirements can reduce uncertainty around the management and redemption of digital assets. MiCA also sets additional conditions for stablecoins denominated in currencies other than the euro when they are used as a means of exchange in the EU, a provision that applies to dollar-pegged tokens serving European users.

EURC is structured around a full-reserve model, with reserves segregated and subject to monthly attestations by independent third parties. Eligible users can redeem EURC for euros at a one-to-one rate through Circle’s Mint platform.

Circle said these features are intended to provide greater transparency and confidence for businesses using EURC for payments, treasury operations and settlement. The combination of regulatory compliance and reserve disclosures has helped position the stablecoin for institutions seeking digital representations of euros.

Payments and Custody Integrations Expand Utility

Beyond trading markets, integrations with payment and custody providers have broadened EURC’s practical uses. Payment companies including MoonPay, Transak and Mercuryo have added support for EURC, allowing users to transact in a euro-denominated stablecoin without necessarily converting through dollar-based assets.

Institutional custody providers such as Fireblocks, Copper and Cobo have also incorporated EURC into their platforms. These integrations can enable businesses to use the stablecoin for treasury management, transfers and settlement while maintaining access to institutional-grade custody infrastructure.

EURC has surpassed €400M in circulation.

Over the past year, EURC supply increased by more than 100% as euro stablecoin adoption moved from experimentation toward real usage across exchanges, payments, and institutional workflows.

Visa and Mastercard have also expanded stablecoin settlement capabilities to include EURC. Those developments have opened potential applications involving cross-border payments, card-linked transactions and merchant settlement denominated directly in euros.

By mid-2026, the expanding network of integrations had moved EURC beyond a relatively specialized cryptocurrency product toward a broader payment and financial settlement instrument.

Euro Stablecoins Remain a Small Part of the Monetary System

Despite EURC’s rapid expansion, euro stablecoins remain a very small part of Europe’s overall monetary system. The eurozone’s M2 money supply exceeds €16 trillion, while the combined euro stablecoin market remains below 0.01% of that figure.

That gap highlights the potential addressable market if blockchain-based payments gain wider adoption. Real-time settlement, lower operational costs and programmable transactions could encourage businesses and financial institutions to incorporate stablecoins into existing payment and treasury systems. The sector is also developing alongside the European Central Bank’s digital euro project, which entered its preparation phase in late 2023; the ECB has not taken a final decision on issuing the retail central bank digital currency, and how private euro stablecoins and a potential state-issued digital euro would coexist remains an open question for European payments.

EURC’s expansion across blockchains, payment networks and institutional custody platforms could position it for additional growth as regulatory certainty and digital-payment infrastructure develop across Europe.

Circle’s strategy has centered on compliance, transparency and interoperability as it seeks to establish EURC as a major component of the emerging euro-based digital asset economy. With circulation now above €400 million and institutional infrastructure continuing to expand, EURC has strengthened its position in the rapidly developing euro stablecoin sector.
