1. USDC EBA supervision: what changes on November 12
Circle's European issuer of USDC will report to the European Banking Authority (EBA) rather than France's ACPR on reserves, liquidity and capital from November 12, after the EBA announced on October 14 that USDC is the first e-money token (EMT) classed as significant under the EU's Markets in Crypto-Assets Regulation (MiCA).
The decision moves the most financially sensitive parts of the dollar stablecoin's European operation to a bloc-wide authority. It is the first time MiCA's significance test has been applied to a token and come out positive, which makes it a reference point for every other issuer operating in the European Union.
The change does not remove the French regulator from the picture. The ACPR, the Autorité de Contrôle Prudentiel et de Résolution, remains responsible for a defined set of duties, and the two bodies are expected to coordinate closely while the handover takes effect.
2. Why was USDC classified as significant?
The EBA judged that USDC met MiCA's threshold for significant status, and in doing so it became the first of the EMTs notified under the regulation to receive that label. The agency said 45 e-money tokens have been notified across the EU so far, and described USDC as the first one to be classified as significant.
The announcement did not spell out which of the significance criteria the token satisfied. It also gave no figures on the size of USDC, so observers cannot see from the notice alone how far the token cleared the bar or which indicator tipped the balance.
Significance is generally judged by how large and widely used a token has become, which is why the label tends to follow scale. Classification is not permanent. The EBA reviews each one annually, which means the status can in principle be confirmed, withdrawn or applied to other tokens as markets develop. For now, USDC is the only e-money token carrying the designation, and the issuer must adjust its supervisory relationships accordingly.
3. Who oversees what after the handover?
MiCA sets up what it calls dual supervision for significant e-money tokens, splitting responsibilities between the EBA and the national authority that licensed the issuer. In this case the issuer is Circle Internet Financial Europe SAS, which holds an electronic money institution license granted by the ACPR, France's banking and insurance supervisor.
Under the new arrangement the EBA takes charge of capital requirements, the asset reserve, liquidity, and recovery and redemption plans. These are the areas that determine whether holders can get their money back at par, and they are the core of what makes a stablecoin safe or fragile.
The ACPR keeps governance, qualifying holdings, fit-and-proper checks, outsourcing and conflicts-of-interest oversight. In practical terms, the French authority still looks at who owns and runs the issuer and how it manages its internal arrangements, while the EBA examines the balance sheet that backs the token.
The EBA said the two regulators will work closely together to ensure a smooth transition and effective cooperation. The date of November 12 marks the point at which the reserve, liquidity and capital reporting line formally changes.
4. The U.S. side and cross-border information sharing
USDC is issued in the United States by a separate entity, Circle Internet Financial, LLC, which is distinct from the French-licensed subsidiary that serves the European market. The two arms issue the same brand of dollar token under different regulatory regimes.
In its announcement the EBA pointed to a memorandum of understanding with the New York State Department of Financial Services, made public in June, which provides for the sharing of information on cross-border stablecoin activity. The reference signals that European supervisors expect to consult their American counterparts as they take on direct oversight of a token whose reserves and users span both markets.
Cooperation of this kind matters because stablecoins move across borders with little friction. A token issued by affiliated companies in two jurisdictions can be redeemed, transferred and held anywhere, so supervisors in each place depend on the others for a complete view of how the issuer is performing and whether its reserves are intact.
5. What is MiCA and what are e-money tokens?
MiCA is the European Union's comprehensive rulebook for crypto-assets, setting common standards for issuers and service providers across member states. Its stablecoin provisions distinguish between asset-referenced tokens and e-money tokens, the latter being tokens that track a single official currency such as the U.S. dollar or the euro.
E-money tokens must be issued by licensed institutions and backed by reserves that can be redeemed on demand. The regulation also creates a higher tier for tokens that grow large enough to matter to the wider financial system, which is the category USDC has now entered. Moving such tokens under the EBA's direct watch reflects a view that a very large stablecoin is an EU-wide concern rather than a purely national one.
Circle has long positioned itself as an early adopter of this framework. In July 2024 the company said its French license made it the first global stablecoin issuer to comply with MiCA. Circle later went public, listing its shares in June 2025, and the new classification adds a further layer of regulatory scrutiny to a business that now answers to public-market investors.
6. Circle's push on reserve rules
The ruling comes shortly after Circle weighed in on the future of the regulation itself. In a blog post on October 1, the company published its response to the European Commission's review of MiCA, setting out changes it wants to see in how reserves are held.
Circle pointed out that MiCA requires issuers of e-money tokens to keep at least 30% of their reserves as commercial bank deposits. For tokens designated as significant, the floor rises to 60%. USDC now falls into that stricter bracket, so the argument the company made two weeks before the classification has immediate relevance to its own operations.
The company contended that the deposit requirement increases exposure to credit and counterparty risk in the banking sector. Concentrating a large share of reserves in bank deposits ties the safety of a stablecoin to the health of the lenders holding the cash. Circle backed replacing the rule with a looser liquidity standard that would let issuers rely on other highly liquid assets.
The EBA's announcement did not address the deposit requirement, and it is not clear whether the new supervisory arrangement will change how the rule is applied in practice. Circle had not published a statement on the classification as of the time the news emerged.
7. Why does the choice of supervisor matter for stablecoin holders?
A stablecoin is only as dependable as the assets behind it and the ability of its issuer to turn those assets into cash when holders ask for redemption. For that reason, supervisors of fiat-backed tokens concentrate on reserves, liquidity and capital, which are exactly the functions now passing to the EBA.
Capital requirements give an issuer a buffer to absorb operational losses without touching the funds set aside for holders. Liquidity rules make sure that a wave of redemption requests can be met quickly. Recovery and redemption plans describe how the issuer would wind down in an orderly manner if it ran into difficulty, so that holders are repaid rather than left waiting.
Placing these elements with a single European authority, instead of a national one, can produce more uniform treatment across the bloc. It also reflects the scale involved. A token used by customers in many member states creates risks that do not stop at the French border, and a supervisor with a union-wide mandate is better placed to assess them.
For Circle, the arrangement means building a working relationship with a second regulator while maintaining the existing one. The firm will deal with the EBA for the financial resilience of the token and with the ACPR for how the company is owned, run and organized. The EBA has said it will work with the French supervisor to keep the transition orderly.
8. What the ruling leaves unanswered
Several questions remain open after the EBA's notice. The agency did not disclose the criteria that USDC satisfied or the numbers behind the decision, so the market has no precise measure of how close other tokens may be to the same line.
It is also uncertain what the shift means for the daily mechanics of Circle's European business. The notice describes who will supervise which functions, but it does not describe new obligations, changes to reserve composition, or any adjustment in how holders redeem tokens. Those details will emerge as the EBA begins to receive reporting from the issuer.
For users, the practical message is one of continuity with tighter oversight. Redemption rights and reserve backing remain the pillars of the model, and the move places the reserve itself under a pan-European supervisor instead of a single national one.
9. What's next for USDC and MiCA oversight
The next fixed date is November 12, when Circle's EU issuer begins reporting to the EBA on reserves, liquidity and capital. From that point the agency becomes the primary supervisor of the parts of the business that determine whether the token can be redeemed.
Beyond that, attention will turn to the European Commission's review of MiCA, to which Circle has already submitted its views on the 30% and 60% bank-deposit thresholds. Whether the review leads to a looser liquidity standard remains to be seen. The EBA's annual reassessment of each classification adds another checkpoint, and further e-money tokens among the 45 notified could eventually be tested against the same significance bar.
