The European Banking Authority began supervising Circle's USDC on Nov. 12, making the dollar-pegged token the first significant e-money token to be pulled into a joint EU oversight structure, according to a report by Coindoo. The handover follows an EBA decision dated Oct. 14 that classified USDC as systemically relevant under the bloc's Markets in Crypto-Assets framework, known as MiCA.
The arrangement splits responsibility. The EBA now oversees the own funds, reserve, liquidity and recovery and redemption planning of Circle Internet Financial Europe SAS, the issuer's French entity, while France's ACPR retains authority over governance and ownership. USDC is one of 45 e-money tokens notified under MiCA and the only one to cross the significance threshold. The EBA has not disclosed which of the regulation's seven criteria USDC met, noting that three are sufficient.
The regulator stressed that the change represents a shift of supervisor rather than any finding against Circle. Nothing in the announcement points to an inspection, penalty or shortfall.
What the new arrangement changes is who can ask questions that Circle's public reserve report was never built to answer. The company's latest examination report, dated Oct. 26, tests a single assertion: that reserve assets were worth at least as much as the USDC in circulation at 23:59 UTC on Sept. 4 and Sept. 30. Independent accountants gave reasonable assurance on that claim under AICPA attestation standards. At Sept. 30, reserves stood at roughly $73.96 billion against 73.88 billion USDC, a surplus of about $78 million, or roughly 0.1%.
Three gaps sit outside that test. The report covers the U.S. issuer and the French issuer together, so it does not break out how much of the reserve backs tokens Circle France has put into circulation. It says nothing about the capital held by the French entity, because accountants were not asked to examine it. And it captures two midnight snapshots rather than showing how quickly those assets could be converted to cash if holders redeemed in force. The EBA's remit covers only the French entity; Circle Internet Financial, LLC, the U.S. issuer, is regulated in New York, which is why the two supervisors now depend on each other.
The capital question is the one the surplus cannot answer. Under Article 58 of MiCA, an e-money institution issuing a significant token must follow the own-funds rule written for significant asset-referenced tokens: capital of at least 3% of the average reserve, up from 2% for non-significant issuers. On a reserve of ā¬1 billion (approximately $1.1 billion), that equates to ā¬30 million (approximately $33.2 million) of the issuer's own capital. The EBA's technical standards give an issuer a procedure and up to three months to reach the higher level after classification.
Own funds are the issuer's equity, held on its own balance sheet in the same high-quality form required of banks. They are not the reserve, and they are not the gap between the reserve and the tokens. The $78 million surplus speaks only to backing; it says nothing about whether Circle France holds the capital MiCA demands.
Liquidity oversight moves beyond balances as well. Circle France must maintain a liquidity management policy with procedures for meeting redemption requests and must run regular liquidity stress tests. From the date of the classification decision, its reserve must also be independently audited every six months, rather than the standard annual cycle for non-significant issuers.
Those documents address the question a treasurer holding USDC asks before a large payment: not whether the assets were present at midnight on Sept. 30, but what happens if many holders want dollars on the same morning. A reserve can be fully valued and still take time to convert. Stress-test results, redemption procedures and the recovery and redemption plans the EBA now reviews provide that evidence, and none of them appears in the monthly report.
MiCA gives the EBA three channels to obtain information. It can issue a binding decision requiring an issuer to hand over data, a step that is enforceable and open to court challenge. It can investigate records, procedures and explanations. And it can conduct on-site inspections at the issuer's premises, with legally privileged material protected. The EBA describes its supervisory model as continuous off-site monitoring combined with targeted on-site work on specific risk areas. If supervision uncovers an infringement, the regulation allows the authority to order the conduct to stop, impose fines and apply periodic penalty payments, each under its own procedure.
Because the reserve is shared with a U.S. issuer, the EBA also needs information that New York regulators hold.
A separate report from NewsBTC noted that Circle has provided USDC reserve information to EU regulators as part of the process. Reserve disclosure is central to stablecoin oversight, since supervisors want assurance that every token in circulation is backed by liquid, verifiable assets. Sharing that data with a supranational body rather than a single national authority adds another layer of scrutiny to Circle's reporting obligations. The same report said the heightened oversight could lead to higher fees for USDC users, since additional supervisory requirements typically carry administrative and operational costs that issuers may pass on through transaction or conversion charges. The exact scale of any increase has not been specified.
Note: Reserve and circulation figures come from Circle's examination report dated Oct. 26, covering positions at 23:59 UTC on Sept. 4 and Sept. 30.
The immediate market impact centers on operating costs rather than USDC's peg or liquidity. If compliance expenses rise, Circle may adjust fee structures for users and institutional partners in the EU, though specifics have not been disclosed. More broadly, the step signals that EU authorities intend to actively enforce MiCA's stablecoin provisions rather than treat them as a formality. Other large stablecoin issuers operating in Europe could face similar dual supervision arrangements, potentially reshaping competition between regulated euro- and dollar-pegged tokens in the region.
Circle has marketed USDC as a heavily regulated alternative to other dollar-pegged tokens, emphasizing transparency around its reserves. Entering a dual supervisory structure in the EU could reinforce that positioning even as it introduces new compliance costs. For an issuer competing on trust and regulatory standing, deeper oversight may serve as both a burden and a selling point.
The significance classification is reviewed annually, and most supervisory findings will remain confidential. Whether the arrangement translates into meaningfully higher fees for users will become clearer as Circle adapts to its expanded obligations.
