Size Matters: EBA designates Circle's USDC the EU's first "significant" e-money token under MiCA
The European Banking Authority (EBA) has classified USDC as the European Union's first "significant" e-money token (EMT) under the Markets in Crypto-Assets Regulation (MiCA), picking Circle's dollar-pegged stablecoin out of 45 EMTs notified across the bloc.
From 12 November 2026, direct supervision of USDC's own funds, reserve assets, liquidity requirements and recovery and redemption plans moves from France's Autorité de contrôle prudentiel et de résolution (ACPR) to the EBA itself — the first time Brussels, rather than a national regulator, holds the reins on a stablecoin's financial safeguards.
Splitting the bill
MiCA doesn't hand the EBA the whole responsibility for supervision, which is split under Article 117 of MiCA:
the EBA takes own funds, reserve assets, liquidity requirements, and recovery and redemption plans; and
the ACPR keeps corporate governance, qualifying ownership interests, management suitability assessments, outsourcing arrangements, and conflicts of interest.
The two regulators say they will work closely together through the transition, and Circle's existing electronic money institution licence, granted by the ACPR in July 2024, is untouched; the significant designation creates no new licensing requirement and changes none of the underlying rules impacting USDC.
(Digital) Papers, please
The classification of USDC is created in EBA Decision EBA/DC/558, which sets the procedure for assessing e-money tokens and asset-referenced tokens against the significance indicators in Commission Delegated Regulation (EU) 2024/1506. Factors such as holder numbers, transaction volume and token value are relevant and are measured under MiCA Articles 43 and 56. The EBA must reassess annually whether USDC still meets these requirements, and will chair a supervisory college under Article 119 for as long as it does.
Across the pond
Because USDC is issued on both sides of the Atlantic — by Circle Internet Financial Europe SAS in the EU and Circle Internet Financial, LLC in the US — the EBA has also signed a memorandum of understanding with the New York State Department of Financial Services to share information on cross-border stablecoin activity. It is a small but significant point of co-operation: a euro-area regulator and a US state banking regulator now have a direct channel in relation to the same token.
The timing is pointed. Circle spent the first half of October lobbying Brussels to loosen MiCA's reserve rules, arguing that the requirement to hold part of reserves in bank deposits exposed it to exactly the kind of bank-failure risk that trapped $3.3 billion of USDC reserves when Silicon Valley Bank collapsed in 2023. The EBA's answer has been, in effect, tighter oversight rather than looser rules.
What now?
Firms dealing with USDC, or advising clients who hold or accept it, should:
confirm which USDC-related compliance obligations now run to the EBA rather than the ACPR, particularly anything touching reserve composition, liquidity or redemption procedures;
watch for further "significant" classifications — 44 other notified EMTs remain under review, and the same indicators could catch other widely-held euro- or dollar-pegged tokens; and
note the EBA-NYDFS memorandum of understanding as an early sign that EU and US regulators intend to compare notes directly on cross-border stablecoins, rather than relying solely on issuer-level disclosure.
The approach sits apart from the US and UK models, which have so far relied on trust-company and state-level chartering for dollar stablecoins and a forthcoming FCA cryptoasset regime respectively, rather than a dedicated "significant token" tier with its own EU-level supervisor.
Whether the extra layer of Brussels oversight becomes a template that other jurisdictions borrow from, or a compliance burden issuers route around by staying just under the threshold, will say a good deal about where stablecoin regulation goes next. It will also be interesting if any data around supervision, its effectiveness and cost, will be collected from this exercise.
