USDC MiCA Regulation: What EBA Supervision Means in 2026

USDC MiCA Regulation: What EBA Supervision Means in 2026

Custom Image
Since MiCA took effect, USDC has operated within the EU’s regulatory framework for stablecoins. Now, it faces a new level of scrutiny. On October 14, 2026, the European Banking Authority (EBA) classified USDC as the EU’s first significant e-money token.
 
From November 12, key prudential supervisory responsibilities will transfer from France’s ACPR to the EBA. These include oversight of the issuer’s own funds, reserve assets, liquidity requirements, and recovery and redemption plans.
 
For USDC holders, the decision does not automatically change their balances or redemption rights. The bigger shift is who oversees the financial backing of the token and how its issuer manages reserves and liquidity.
 
The decision also raises questions about MiCA’s significance criteria, why USDC met the threshold, and what closer supervision means for competing stablecoins and crypto exchanges.
 
Here is what changes, what remains the same, and what users should know before trading stablecoins in the EU.
 

What Did the EBA Decide About USDC, and When Does It Take Effect?

The European Banking Authority’s (EBA) decision places USDC in a distinct supervisory category among the e-money tokens registered under MiCA, with a new division of oversight beginning on November 12, 2026.
 

When Did the EBA Classify USDC as a Significant E-Money Token?

On October 14, 2026, the EBA announced that USDC, issued in the EU by Circle Internet Financial Europe SAS, has been classified as a significant e-money token. It is the first of 45 e-money tokens notified under MiCA to receive this designation. An e-money token (EMT) is a stablecoin that references a single official currency, such as the US dollar.
 
The classification takes effect on November 12, 2026, leaving approximately four weeks for transition. The EBA and France’s ACPR have stated that they will work closely together to ensure a smooth handover, and the EBA reassesses the status of each token annually.
 

What Makes an E-Money Token “Significant” Under MiCA?

A significant e-money token is a stablecoin that the EBA has classified as large enough to pose risks beyond a single issuer or country. The regulator assigns this status, and it places the issuer under the dual supervision of the EBA and the national authority.
 
To qualify, a token must meet at least three criteria under Article 43 of MiCA. These include more than 10 million holders, a market value above €5 billion, more than 2.5 million daily transactions worth over €500 million, and material links to the wider financial system.
 
The EBA has not disclosed which criteria USDC met, so any specific threshold should be treated as an estimate.
 

EBA vs. ACPR: Who Supervises USDC After November 12?

Under MiCA, significant e-money tokens are subject to dual supervision. From November 12, the European Banking Authority (EBA) will oversee USDC’s own funds, reserve assets, liquidity requirements, and recovery and redemption plans.
 
These responsibilities transfer from France’s ACPR to the EBA following USDC’s classification as a significant e-money token.
 
The ACPR will retain responsibility for USDC issuer Circle’s governance, qualifying holdings, fit and proper assessments, outsourcing arrangements, and conflicts of interest. This division allows the EBA to focus on the financial safeguards supporting redemption while the ACPR continues to supervise the issuer’s governance and ownership.
 
The classification does not change USDC’s dollar peg or mean the EBA guarantees the token. Instead, it introduces additional oversight of the financial and operational safeguards underpinning USDC within the European Union.
 

How MiCA’s Significant Stablecoin Rules Affect USDC

USDC’s significant classification brings additional requirements for reserve management, financial safeguards and independent audits under MiCA. These rules focus on how Circle protects the assets backing USDC and maintains its ability to meet redemption requests.
 

Stricter Reserve Management Requirements

Under Article 58, significant e-money token issuers must comply with MiCA’s rules on reserve management, custody and investment. These requirements aim to protect the assets backing USDC and ensure they remain available to support redemption requests.
 
For USDC, the key requirements include:
  • Reserve protection: Safeguarding the assets backing tokens in circulation.
  • Custody: Keeping reserve assets under the applicable custody arrangements.
  • Investment: Following rules governing how reserve assets may be invested.
 

Higher Capital Requirements and More Frequent Audits

Article 58 also applies specific own-funds and liquidity requirements to significant e-money token issuers. These financial safeguards help the issuer manage risks and maintain its ability to meet obligations.
 
Independent audits must take place every six months after classification, giving regulators more frequent checks on compliance. The exact capital requirements should be described using the provisions applicable to significant e-money tokens, rather than automatically applying rules written specifically for asset-referenced tokens.
 

What the New Rules Mean for USDC Holders and Exchanges

USDC’s classification does not automatically change its dollar peg or holders’ redemption rights. Under Article 49 of MiCA, holders of e-money tokens have a claim against the issuer and may request redemption at par value.
 
The EBA’s announcement does not itself order exchanges to delist USDC. The immediate regulatory change concerns Circle’s obligations as an issuer; any separate changes to deposits, withdrawals or trading access would depend on the applicable rules and individual platforms’ decisions.
 

USDC vs. USDT in Europe: How MiCA Changed Stablecoin Trading

MiCA has changed which stablecoins EU-authorised crypto platforms can offer. The key distinction is regulatory compliance, not simply market size: USDT remains the larger stablecoin globally, but USDC has an authorised EU issuer and is subject to the EU’s e-money token framework.
 

Why MiCA Restricted USDT Trading on EU-Regulated Exchanges

Tether’s USDT does not appear on the EU’s register of MiCA-authorised e-money token issuers. As a result, crypto-asset service providers authorised under MiCA must stop providing services involving non-compliant stablecoins to EU clients. ESMA reiterated this requirement on October 8, 2026, including restrictions on trading, exchange and custody services.
 
This does not mean individuals are prohibited from owning USDT. The restriction primarily concerns the services regulated platforms can provide to EU clients. ESMA allows limited, supervised arrangements for existing holdings to be liquidated, converted, withdrawn, transferred or kept in custody during an orderly transition. Availability may therefore differ by platform and service.
 

USDC vs. USDT: Market Size and Regulatory Status

USDT remains the larger stablecoin by market capitalization, despite the restrictions on its availability through EU-regulated platforms. On October 15, 2026, USDT had a market capitalization of approximately $184 billion, compared with about $72.6 billion for USDC, according to coinmarketcap data.
 
The difference is regulatory access. Circle’s French entity is authorised to issue USDC as an e-money token under MiCA, allowing compliant EU platforms to offer it subject to their own obligations.
 
Tether, by contrast, does not have a corresponding MiCA-authorised EU issuer for USDT. This gives USDC a clearer route to trading and settlement services on regulated European platforms, even though USDT remains larger globally.
 

How Many Major Stablecoins Comply With MiCA?

MiCA compliance remains limited among the largest stablecoins. In an October 2026 policy statement, Circle’s EU strategy director, Patrick Hansen, said that only three of the world’s top 30 stablecoins met MiCA requirements: USDC, EURC and USDG. This is Circle’s assessment, not an official ranking published by EU regulators.
 
The limited number of compliant tokens highlights a gap between global stablecoin adoption and access to regulated European markets. For exchanges, compliance affects which stablecoins they can offer to EU customers.
 
For users and businesses, it makes checking a token’s regulatory status and a platform’s regional restrictions increasingly important before choosing a stablecoin for trading or transfers.
 

What Could Change for Stablecoins Under MiCA in 2027?

Circle has asked the European Commission to revise parts of MiCA that govern stablecoin issuance and reserve management. Its proposals focus on preserving multi-issuance, making reserve requirements more flexible, and helping major global stablecoins operate within the EU’s regulatory framework.
 
These are proposals for reform, not changes to the rules currently in force.
 
The Commission’s review could lead to changes in 2027, but the final outcome will depend on the legislative process and how policymakers respond to industry and regulatory recommendations.
 

Which MiCA Rules Does Circle Want to Change?

Circle wants the EU to preserve multi-issuance, a model in which an EU-authorised entity and a foreign-regulated affiliate issue the same stablecoin across jurisdictions. Circle argues that restricting this arrangement could push users toward offshore stablecoins outside MiCA’s protections. It recommends formal safeguards, including mechanisms to rebalance reserves between EU and global operations.
 
Circle also wants to revise MiCA’s reserve rules. Currently, e-money token issuers must hold at least 30% of reserves as bank deposits, rising to 60% for significant tokens.
 
Circle argues that fixed deposit requirements increase exposure to bank counterparty risk and should be replaced with more flexible liquidity standards. It has also called for changes to limits on exposure to individual banks and sovereign debt.
 

Why Do European Regulators Have Concerns About Circle’s Proposals?

The European Central Bank (ECB) and other EU central banks share concerns about mandatory bank-deposit thresholds, but they take a more cautious position on multi-issuance.
 
They warn that stablecoin issuers’ deposits can be less stable than ordinary retail deposits, potentially creating risks for banks. Instead of fixed deposit percentages, they have proposed requiring a portion of reserves to mature within one to five working days.
 
On multi-issuance, the European Banking Authority (EBA) has urged the Commission to consider stronger safeguards for arrangements involving issuers outside the EU.
 
Regulators are concerned that redemption pressure could shift rapidly across jurisdictions, while reserves may be fragmented or difficult to transfer during a crisis. Any reform must therefore balance broader market access with effective oversight and sufficient protection for EU holders.
 

How Could MiCA’s 2027 Review Affect Stablecoin Issuers?

The review could change how stablecoin issuers manage reserves and structure their operations across jurisdictions. If policymakers adopt more flexible liquidity rules, issuers could gain greater choice in managing reserve assets.
 
If multi-issuance remains permitted under a clearer framework, globally used stablecoins may have a more defined route to serving EU customers through authorised entities. Neither outcome is guaranteed, and the existing requirements remain in force until changes are formally adopted.
 
The review could also affect which major stablecoins can compete in regulated European markets. For issuers, the key signals to watch are the Commission’s response to the consultation, any proposed legislative amendments, and the final rules governing reserves and cross-border issuance.
 

Conclusion

The EBA’s classification of USDC as a significant e-money token introduces stricter oversight of Circle’s reserves, liquidity and financial safeguards under MiCA. While the designation does not automatically change USDC’s dollar peg or redemption rights, it gives the EBA a greater role in supervising the token’s financial backing.
 
Meanwhile, USDT’s lack of MiCA authorisation restricts its availability through EU-regulated platforms, giving compliant stablecoins such as USDC an advantage in the European market.
 
Looking ahead, Circle’s push to revise MiCA’s reserve requirements and multi-issuance rules could shape the next phase of stablecoin regulation in Europe. However, any changes remain subject to the EU’s review and legislative process. For users, exchanges and stablecoin issuers, the key factors to watch are regulatory compliance, reserve safeguards and how the framework evolves in 2027.

FAQs

Why did the EBA classify USDC as a significant e-money token?

The EBA classified USDC as significant under MiCA’s criteria for large e-money tokens. However, it has not disclosed which specific thresholds USDC met.

When does USDC’s significant MiCA classification take effect?

The classification takes effect on November 12, 2026. From that date, the EBA assumes direct responsibility for key prudential supervision, while France’s ACPR retains other supervisory duties.

Is USDC still safe to use under MiCA?

The classification introduces stricter oversight of USDC’s reserves, liquidity and financial safeguards. However, it does not guarantee USDC’s value or eliminate the risks associated with stablecoins.

Why is USDT restricted on EU-regulated exchanges?

Tether has not obtained the required MiCA authorisation for USDT. Consequently, EU-authorised crypto platforms face restrictions on offering related services, although individual ownership of USDT is not generally prohibited.

Will MiCA’s stablecoin rules change in 2027?

The European Commission is reviewing MiCA, including reserve requirements and multi-issuance rules. Changes could follow in 2027, but Circle’s proposals remain unadopted, and the outcome is uncertain.
