The European Banking Authority has classified USDC as the European Union’s first significant e-money token under MiCA, moving key parts of the stablecoin’s European supervision directly to the EU-level regulator. The new supervisory structure takes effect on November 12, 2026, and applies to Circle Internet Financial Europe SAS as the EU issuer of USDC.
According to the EBA’s official announcement, USDC is the first of 45 e-money tokens notified under MiCA to receive significant status. The designation does not alter how the token works or introduce a new version of USDC; it changes the prudential oversight applied to its European issuer.
Circle’s French entity has issued USDC and EURC within the European Economic Area since receiving an electronic-money institution license from France’s ACPR in 2024. USDC is also issued outside Europe by Circle Internet Financial LLC. The EBA’s new supervisory powers concern the MiCA-regulated European issuance structure rather than extending direct EU supervision over Circle’s U.S. entity.
EBA Takes Over Reserves and Liquidity Oversight
From November 12, the EBA will directly supervise Circle Europe in four areas: own funds, reserve assets, liquidity requirements, and recovery and redemption plans. These responsibilities address the financial resources supporting USDC and the issuer’s ability to meet redemption obligations during normal operations or periods of stress.
France’s ACPR will remain responsible for other parts of Circle Europe’s regulatory perimeter, including governance, qualifying holdings, management suitability, outsourcing and conflicts of interest. The arrangement is therefore a dual-supervision structure rather than a complete transfer of regulatory authority from France to Brussels.
MiCA requires an e-money token to satisfy at least three statutory significance criteria before the EBA classifies it as significant. Those criteria include thresholds relating to holders, token value or reserves and transaction activity, alongside qualitative factors such as international scale and financial-system interconnectedness. The EBA confirmed that USDC qualified but did not specify in its announcement which individual criteria produced the final determination.
The classification comes as Europe develops a larger regulated stablecoin market. Kraken recently moved to list the MiCA-regulated USDSM stablecoin, while AllUnity launched USDAU across six blockchain networks. Those products remain separate EMTs with their own issuers, reserves and supervisory arrangements and are not automatically subject to USDC’s significant-token regime.
Significant Status Adds Oversight, Not a New Peg
The designation also does not change USDC’s basic redemption structure. Circle Europe continues to issue the token as an e-money token backed by eligible dollar-denominated assets and subject to MiCA’s existing requirements. Significant status adds an enhanced layer of supervision because the consequences of reserve, liquidity or redemption failures can become more material as a token grows.
Cross-border oversight will also become more relevant. The EBA has signed a memorandum of understanding with the New York State Department of Financial Services to facilitate cooperation and information exchange involving stablecoins operating across European and U.S. jurisdictions.
The move comes as European banks develop regulated stablecoin infrastructure and MiCA shifts from rulemaking toward day-to-day supervision. USDC is now the first practical test of how MiCA’s significant-EMT framework operates for a stablecoin already used extensively across global crypto and payment infrastructure.
The immediate consequence is regulatory rather than technical: from November 12, the EBA will directly oversee the reserve, liquidity, capital and recovery framework supporting EU-issued USDC while the ACPR continues supervising the remaining parts of Circle Europe’s business.
