EU Names USDC Its First 'Significant' Stablecoin: What EBA Supervision Changes From November 12

Published October 16, 2026 (data of October 15). The European Banking Authority (EBA) has classified Circle's USDC as a significant e-money token under MiCA, the first of the 45 e-money tokens notified in the EU to get that label. From November 12, 2026, the EBA itself will supervise USDC's reserve, liquidity, own funds and recovery and redemption plans, while France's ACPR keeps governance. The EBA also signed a cooperation agreement with New York's financial regulator, which oversees Circle's US arm.

Key takeaways

The EBA classified USDC as the first significant e-money token (EMT) in the EU on October 14, 2026 (EBA press release). 45 EMTs have been notified under MiCA.
Dual supervision starts November 12, 2026: the EBA takes over own funds, reserve of assets, liquidity and recovery and redemption plans; the ACPR keeps governance, qualifying holdings, fit-and-proper checks, outsourcing and conflicts of interest.
MiCA then applies stricter rules: own funds of 3% of average reserve assets (Article 45(5)), liquidity and stress-testing duties (Article 45(1) to (4)) and an independent reserve audit every six months (Article 58).
Our calculation: USDC's circulating supply of $72.68 billion (DefiLlama, October 15) equals about €64.8 billion at the ECB reference rate, roughly 13 times MiCA's €5 billion size threshold. The EBA did not say which criteria it found to be met.
The EBA signed a memorandum of understanding with the New York State Department of Financial Services to share information on cross-border stablecoin activity.

What the EBA decided

Under MiCA, national authorities supervise stablecoin issuers by default. Once a token becomes large or interconnected enough, the EBA can classify it as significant and step in. For asset-referenced tokens, the EBA becomes the sole supervisor. For e-money tokens like USDC, supervision is split (MiCA Article 117). The EBA says it reassesses the classification every year.

USDC is issued in the EU by Circle Internet Financial Europe SAS, an e-money institution authorised in France, and in the US by Circle Internet Financial, LLC. That two-issuer structure is why the New York agreement matters: the reserves that back tokens in the hands of EU users are supervised on both sides of the Atlantic.

The MiCA test: how USDC compares

MiCA Article 43, which also applies to e-money tokens through Article 56, lists seven criteria. A token is classified as significant when at least three are met. The detailed indicators are set out in Commission Delegated Regulation (EU) 2024/1506.

MiCA criterion (Art. 43(1))	Threshold	What we can check for USDC
(a) Number of holders	More than 10 million	Not published by the EBA
(b) Value issued, market cap or reserve	More than €5 billion	About €64.8 billion in global supply (our calculation)
(c) Daily transactions	More than 2.5 million and €500 million	Not published by the EBA
(d) Issuer is a DMA gatekeeper	Yes/No	Circle is not a designated gatekeeper
(e) International scale, payments and remittances	Qualitative	Issued in the EU and the US
(f) Interconnectedness with the financial system	Qualitative	Not detailed by the EBA
(g) Issuer issues another EMT/ART and provides a crypto-asset service	Yes/No	Circle also issues EURC; services not assessed here

Our calculation: 72.68 billion USDC (DefiLlama, Oct. 15, 2026) / 1.1208 (ECB euro reference rate for Oct. 15) = €64.84 billion. The supply figure is global; MiCA's indicators may be measured differently, so this is a scale check, not the EBA's assessment.

Why it matters

A first test case for EU stablecoin supervision. No e-money token had been classified as significant since MiCA's stablecoin rules took effect on June 30, 2024. USDC now sets the template for how the EBA and a national authority share a dollar stablecoin.
Higher capital and more frequent audits. The own-funds floor rises from 2% to 3% of average reserve assets, and reserve audits move to a six-monthly rhythm from the classification date. That is a cost for Circle, but also an extra layer of oversight for users.
The compliant stablecoin gets stronger as others exit. ESMA has told EU platforms to wind down non-MiCA stablecoins such as USDT and PYUSD by January 8, 2027 (our analysis of ESMA's opinion). USDC is now the largest dollar token that is both authorised and directly supervised at EU level.
Transatlantic coordination. The EBA-NYDFS agreement is a practical answer to the "multi-issuance" question: the same token issued by an EU entity and a US entity, with reserves held by each.

Stablecoin market snapshot (October 15, 2026)

Token	Supply	1-month change	MiCA status
USDT (Tether)	$183.76B	+0.3%	Not authorised; EU wind-down by Jan. 8, 2027
USDC (Circle)	$72.68B	-2.3%	Authorised EMT, significant from Oct. 14
USDG (Paxos)	$3.00B	-7.9%	Authorised EMT
PYUSD (PayPal)	$2.80B	-1.9%	Not authorised in the EU
EURC (Circle)	€0.50B	+9.5%	Authorised EMT, not significant

Our calculation from DefiLlama supply data (October 15 vs. one month earlier). Total dollar stablecoin supply: $306.3 billion. MiCA status as reported in our ESMA article, based on the ESMA interim register.

USDC's supply has fallen by about $1.7 billion over the past month, while USDT is roughly flat. The classification is about size and systemic reach, not recent growth.

What to watch next

November 12, 2026: EBA supervision of USDC's reserve, liquidity and own funds begins.
Six-monthly reserve audits: under Article 58, the first one is due within six months of the October 14 decision, so by mid-April 2027.
January 8, 2027: ESMA's deadline for EU platforms to stop offering non-MiCA stablecoins.
Annual review: the EBA reassesses significance every year; other large EMTs (USDG, EURC) could be next if they cross the thresholds.
Circle's response and any update to its EU white paper or reserve reports.

FAQ

What is a significant e-money token?

It is a stablecoin pegged to one currency that the EBA considers large or interconnected enough to need EU-level supervision. MiCA sets seven criteria; at least three must be met.

Does this change anything for people holding USDC?

USDC keeps working as before. The change is in supervision: from November 12, the EBA oversees the reserve, liquidity and capital, and stricter capital and audit rules apply to Circle's EU issuer.

Why is USDT not on the list?

Tether has no MiCA authorisation in the EU, so USDT cannot be classified under MiCA. ESMA has asked EU platforms to wind it down by January 8, 2027.

Who supervises Circle in the EU now?

France's ACPR, which authorised Circle Internet Financial Europe SAS, until November 12. After that date the supervision is shared between the ACPR and the EBA.

Is the classification permanent?

No. The EBA reviews it every year based on the MiCA criteria.
