The European Banking Authority has classified Circle's USDC as a significant e-money token under the Markets in Crypto Assets framework, placing the second-largest stablecoin under joint supervision with France's Autorité de Contrôle Prudentiel et de Résolution.

The EBA announced the designation in a notice published Wednesday. The classification carries direct supervisory weight: USDC will now be overseen jointly by the Paris-based ACPR and the EBA itself, rather than by a single national authority. Only 45 other projects hold the same classification, which places the $73 billion stablecoin in the top supervisory tier of the EU's crypto regime.

The scale is straightforward. USDC's $73 billion market capitalization is roughly 40 percent the size of Tether's USDt, which stands at $184 billion and remains the largest stablecoin in circulation. MiCA's significance thresholds are designed to capture issuers whose failure or misuse could transmit risk across the single market, and a token of USDC's size comfortably clears that bar.

What does the classification change?

For practitioners, the designation moves USDC from ordinary e-money token supervision into the enhanced tier. That means the ACPR, as the competent authority in Circle's EU jurisdiction of authorization, now works alongside the EBA rather than alone. The practical consequence is a second layer of supervisory scrutiny over reserve management, redemption practices and operational resilience for any EU-facing USDC activity.

For exchanges, custodians and payment firms operating in the bloc, the change adds regulatory clarity rather than restriction. A token classified as significant under MiCA is, by definition, fully inside the perimeter. Firms that have waited on the question of which dollar-pegged instruments can anchor EU operations now have the answer for the largest regulated dollar stablecoin available in the region.

Issuers have pushed for regulated dollar tokens

The classification arrives amid sustained pressure from EU-based token issuers for a regulated pathway to dollar-pegged stablecoins. Stable Mint CEO James Bennett told Cointelegraph that Europe could not "wish away" dollar stablecoins, and that regulators instead could shape the safeguards and rules governing issuers.

Alexander Höptner, CEO of AllUnity, framed the demand side in operational terms. "For European corporates to make cross-border payments globally, offering only a euro stablecoin isn't enough," Höptner said. The comment reflects a structural constraint: euro-denominated instruments alone cannot settle dollar-leg invoices, supplier contracts or commodity payments, which keeps dollar-pegged tokens in demand regardless of policy preference.

The dynamic creates a two-track market structure. Regulated dollar stablecoins operate under EBA and national supervision, while unregulated or non-compliant dollar tokens face restricted EU market access. Wednesday's decision consolidates USDC firmly on the first track.

The digital euro remains on a slower clock

While supervisors and issuers converge on regulated dollar stablecoins, the European Central Bank continues to study a digital euro. The ECB first proposed the central bank digital currency in 2020, and a potential issuance could follow in 2029, after the conclusion of legislation and a pilot program.

That timeline leaves a window of roughly five years in which privately issued, MiCA-compliant stablecoins will carry the load of on-chain settlement in the eurozone. Wednesday's classification suggests European authorities have accepted that interim reality and chosen to supervise it rather than resist it.

For Circle, the designation formalizes a supervisory relationship it has effectively been building since securing French authorization. For the broader market, the question now is whether Tether's USDt, which serves a far larger global user base, seeks a comparable EU pathway or continues to operate outside it.
