EBA classifies USDC as EU's first significant e-money token under MiCA, direct supervision begins November 12

The European Banking Authority (EBA) classified Circle's USDC as the European Union's first "significant" e-money token (EMT) under MiCA on October 14, 2026. The direct-supervision shift takes effect on November 12, 2026. The decision is in the EBA's press release, covered by The Block. Of the 45 EMTs notified under MiCA to date, USDC is the first to cross the significance threshold.

What the EBA decided

• Issuer: Circle Internet Financial Europe SAS, Circle's French-licensed MiCA entity.
• Basis: the significance criteria in MiCA, as implemented by Commission Delegated Regulation (EU) 2024/1506 (holder count, outstanding value, daily transactions, cross-border use).
• Scope: the designation attaches to the USDC EMT, not to Circle group-wide.
• MoU on the US side: the EBA signed a memorandum of understanding with the New York State Department of Financial Services, which supervises Circle's New York-regulated operations. The MoU covers cross-border information exchange.

The press release does not publish which of the four significance indicators USDC crossed, nor the exact numeric thresholds the EBA applied. That detail lives in the individual significance decision rather than the public communication.

Who supervises what from November 12

MiCA splits oversight once an EMT becomes significant. The shift effective November 12:

• Transferred to the EBA from the ACPR (France): own funds, reserve-of-assets composition, liquidity requirements, recovery and redemption plans.
• Retained by the ACPR: governance, qualifying holdings, fit-and-proper assessments, outsourcing, conflicts of interest.
• Supervisory college: chaired by the EBA, including the ACPR, Banque de France and competent authorities of other affected member states.

MiCA layers an uplifted prudential regime over significant EMTs — a higher own-funds floor and a larger share of reserves held in deposits at EU-licensed credit institutions. The EBA has not published the quantitative supplements as part of this press release; those apply via the general MiCA framework and will show up in Circle's next prudential reporting.

The numbers

• Global USDC supply: ~$73 billion.
• USDT (reference point): ~$184 billion, still unauthorized under MiCA.
• Total dollar-pegged stablecoin supply: ~$294 billion (The Block's figure).
• EMTs notified under MiCA so far: 45.
• EMTs classified "significant": 1 (USDC).
• European circulation of USDC specific to Circle Internet Financial Europe SAS: not published.
• European holder count: not published.

Why USDC first

Tether has no MiCA EMI authorization in any EU member state for USDT, which places USDT outside the scope of the EBA's significance assessment regardless of its global supply. Significance applies to issuers inside the regime, and Circle is by far the largest of those. Societe Generale-Forge (EURCV), Monerium (EURe) and Circle's own EURC sit well below USDC's EU volume. The near-term pipeline for a second designation is therefore another dollar EMT — Paxos's USDG or a MiCA-authorized USDT, if either materializes — rather than a euro token.

What to watch

1. The individual significance decision. The press release names the regulation but not the indicators USDC breached. Publication of the file-level decision would reveal where the EBA set the quantitative thresholds, and over what measurement window.
2. Circle's prudential filing. The uplifted own-funds and reserve-location requirements become visible in Circle Internet Financial Europe SAS's next capital adequacy and liquidity reports to the EBA.
3. Reserve relocation. Historically, a majority of Circle's reserve sits at BlackRock in the US (Circle Reserve Fund) and at US-regulated banks. The share that must now be held in deposits at EU-licensed credit institutions is the most operationally heavy constraint.
4. The MoU with NY DFS. Whether the information exchange extends to the Circle Reserve Fund's holdings composition would determine how much new disclosure is actually produced.
5. The second trigger. The next MiCA-authorized EMT to approach the significance threshold is the signal to watch, and that is a dollar EMT, not a euro one.

Context

MiCA was drafted to contain dollar-stablecoin reach on euro-area rails by stacking prudential obligations above a threshold of EU circulation. October 14 is the first time the mechanism fired. USDC moves from "authorized EMT" to "EMT under the heavy-regime variant MiCA always foresaw for the most-used tokens." The parallel this site covered on October 15 — Qivalis's EMI license at the DNB for a brand-new 37-bank euro consortium — is the other half of the picture: nascent euro EMT at the ground floor, dominant dollar EMT at the top of the stack. The 2026 MiCA regime is now visibly asymmetric by design.
