EBA Takes Direct USDC Oversight Under MiCA

The European Banking Authority has begun directly supervising key prudential aspects of USDC issued in Europe after the stablecoin became the European Union’s first significant e-money token under MiCA. From November 12, responsibility for supervising Circle Internet Financial Europe SAS in areas including own funds, reserve assets, liquidity and recovery and redemption planning has transferred from France’s ACPR to the EBA. The transition implements the classification announced by the regulator on October 14. The official EBA announcement says USDC is the first significant EMT among 45 e-money tokens notified under MiCA.

The arrangement does not remove France’s national regulator from supervision. The ACPR continues overseeing areas including governance, qualifying holdings, fit-and-proper assessments, outsourcing and conflicts of interest. USDC has therefore entered MiCA’s dual-supervision regime rather than moving entirely from French oversight to a centralized EU regulator. The shift also does not constitute a new authorization for USDC: Circle’s European entity was already permitted to issue the stablecoin before its classification as the EU’s first significant EMT.

Significant Status Raises Prudential Requirements

The designation subjects Circle Europe to additional requirements that apply specifically to significant e-money tokens. MiCA raises the relevant own-funds percentage to 3% of average reserve assets, compared with the 2% benchmark incorporated into the standard reserve framework. Significant EMT issuers must also maintain enhanced liquidity management, conduct regular liquidity stress tests and submit their reserve arrangements to an independent audit every six months.

The stress-testing framework is more granular than a general requirement to demonstrate redemption capacity. EU technical standards require liquidity stress tests at least monthly for EMT issuers, while solvency stress testing must occur at least quarterly for significant issuers rather than semiannually for non-significant ones. The EBA can use those results to require stronger liquidity safeguards when the identified risks justify additional measures.

Circle’s global reserve disclosures should not be treated as a direct measure of compliance with those European requirements. Circle operates USDC through a dual-issuer structure in which Circle Europe maintains reserves for EEA holdings and Circle LLC maintains reserves for holders outside the region. Circle’s MiCA white paper says the European entity’s minimum reserve requirement equals EEA USDC holdings at all times. That means global USDC circulation and reserves cannot simply be multiplied by 3% to determine Circle Europe’s required own funds.

The distinction also makes the September reserve snapshot in the original reporting less useful for assessing the new regime. Circle’s latest public data showed about $68.9 billion of USDC in circulation globally as of November 9, down from the roughly $74 billion range seen earlier in the year. Neither figure reveals the size of the European reserve perimeter or independently establishes compliance with Circle Europe’s capital requirement.

USDC Enters MiCA’s Cross-Border Supervisory Test

USDC’s fungible dual-issuer structure creates a cross-border supervisory issue because identical tokens can circulate while redemption obligations sit with different Circle entities. The EBA has signed a memorandum of understanding with the New York State Department of Financial Services to facilitate regulatory cooperation and information exchange around that structure. The agreement is a supervisory coordination mechanism, not a transfer of U.S. regulatory authority to the EBA.

Circle’s own white paper identifies a related risk: if USDC holdings and redemption demand shift significantly toward the EEA, Circle LLC may need to rebalance reserves toward Circle Europe. A disruption to that process could affect the European entity’s ability to satisfy redemptions promptly. MiCA’s enhanced liquidity supervision is therefore addressing a concrete structural issue created by globally fungible tokens with multiple legal issuers.

The transition arrives as European platforms are simultaneously narrowing access to stablecoins without MiCA-compliant issuance structures. OKX Europe has already limited USDT to a one-way conversion route into USDC, while ESMA has directed regulated crypto platforms to wind down normal services involving non-MiCA stablecoins by January 2027. USDC is moving in the opposite direction: from basic MiCA compliance into the framework’s highest prudential category for e-money tokens.

Significant status will be reassessed annually rather than attaching permanently to USDC. The immediate change is nevertheless concrete: November 12 marks the point at which MiCA’s significant-EMT supervisory structure became operational for the first time, with the EBA directly responsible for Circle Europe’s reserve, capital, liquidity and recovery safeguards while the ACPR retains the rest of its national supervisory mandate.
