ESMA's 8 January 2027 Deadline for Non-MiCA Stablecoins: What EU CASPs Must Do

EU crypto-asset service providers (CASPs) must stop providing services in non-MiCA-compliant stablecoins to EU clients and remediate any remaining client exposure by 8 January 2027, three months after ESMA's opinion of 8 October 2026. A stablecoin is MiCA-compliant only if its issuer meets MiCA's offer rules: an e-money token must be issued by a credit institution or an electronic money institution that has notified a white paper, and an asset-referenced token by an authorised issuer. ESMA's interim register update of 19 October 2026 lists 50 e-money token white paper entries from 25 issuers, and no authorised issuer of asset-referenced tokens. Warnings to clients do not count as remediation.

What ESMA said on 8 October 2026

ESMA published its opinion on crypto-asset services in relation to non-MiCA-compliant asset-referenced tokens and e-money tokens under Article 29(1)(a) of the ESMA Regulation, the power it uses to align how national regulators supervise. An ESMA opinion is not new law. It tells national competent authorities, meaning the regulators that authorise and supervise CASPs, how ESMA expects existing MiCA duties to be applied.

The core of the opinion rests on MiCA Article 66(1): a CASP must act honestly, fairly and professionally in the best interests of its clients. ESMA's view is that offering services in a stablecoin that lacks MiCA's issuer safeguards is not compatible with that duty. The key points are:

• CASPs should cease providing services related to non-MiCA-compliant stablecoins to clients in the EU
• Every service is covered: trading platforms, exchange, execution, order transmission, placing, advice, transfers, custody and portfolio management
• CASPs should apply technical, contractual and organisational controls so EU clients cannot acquire or increase positions
• Warnings, disclosures and client acknowledgements are not enough
• Remaining exposures should be remediated as soon as possible and no later than three months after publication, which is 8 January 2027
• Residual services may continue only for liquidation, conversion, withdrawal, transfer or safekeeping of existing holdings, and must be time-limited, clearly communicated and closely supervised
• ESMA will monitor how national regulators apply the opinion

The opinion follows the end of the MiCA transitional periods. ESMA's statement of 17 April 2026 confirmed that the transitional period would end across the EU on 1 July 2026. Since then, only authorised CASPs and firms using the Article 60 notification route may serve EU clients, apart from genuine reverse solicitation.

Which stablecoins are MiCA-compliant

MiCA divides stablecoins into two types. An e-money token aims to keep a stable value by referring to one official currency, such as a euro or dollar coin. An asset-referenced token refers to another value or right, or a basket of currencies, commodities or crypto-assets. ESMA defines a non-compliant token as one where the conditions for a lawful offer to the public or admission to trading under MiCA Title III or Title IV are not met.

The ESMA e-money token file of 19 October 2026 contains 50 white paper entries from 25 issuers. Of those entries, 44 come from electronic money institutions and 5 from credit institutions. Examples on the register include Circle Internet Financial Europe SAS in France (USDC and EURC), Paxos Issuance Europe Oy in Finland (USDG) and Société Générale-Forge in France (EURCV). The asset-referenced token file contains no entries. The e-money token file contains no entry for Tether's USDT.

Being on the register is the starting point, not the end. CASPs should also check that the version of the token they support, on the network they use, is the one the white paper covers.

How to check every token you support

• List every stablecoin your firm supports for EU clients, on every network, in every product: spot, conversions, earn or staking features, custody and transfers
• Match each one to the issuer's legal entity and to an entry in the ESMA register, recording the date checked
• Confirm the white paper covers the network you use
• Record tokens with no entry as non-compliant
• Repeat the check each time ESMA updates the register, which it does regularly, and before adding any new stablecoin

What CASPs must do before 8 January 2027

Delisting and trading pairs

Delisting has two parts. The first is the token itself: removing it from the list of assets EU clients can buy. The second is every trading pair that uses it as the quote currency. A platform that quotes bitcoin against a non-compliant dollar coin offers a service in that coin, so those pairs need to move to a compliant e-money token or to fiat. Many platforms will need to rebuild order books and liquidity around compliant tokens before 8 January 2027, which takes testing time.

Firms should also check less visible products: automatic conversions at deposit, recurring purchase plans, earn or yield products, collateral settings and default settlement assets. Each one can create new exposure without the client placing an order.

Client communications

ESMA says residual services must be clearly communicated to clients. A good notice tells the client, in plain words:

• Which tokens are affected and why, by reference to MiCA rather than to the token's quality
• The date from which they can no longer buy or increase holdings
• What they can still do: sell, convert to a compliant token or fiat, withdraw to a self-hosted wallet, or transfer to another provider
• The date by which residual services end, if the firm sets one
• How to get help, and how to complain

The notice must not promote any alternative product as part of the same message, because ESMA says residual services must not support promotion. Clients who do nothing should not be left holding an asset the firm can no longer service, so the plan should set out what happens to unclaimed balances.

Controls that restrict new exposure

ESMA asks for three kinds of control. Technical controls are changes in the platform itself: blocking buy orders, disabling deposits into earn products, removing pairs and stopping automatic conversion. Contractual controls are changes to the client terms that reflect the new position. Organisational controls are the governance around it: a listing policy that requires a register check, an owner for each stablecoin decision, and monitoring that confirms the controls work.

One judgement firms need to record is how they treat incoming transfers of a non-compliant token from an external wallet. Accepting them for immediate sale or onward withdrawal may fit within the residual services ESMA describes. Accepting them into a held balance increases the client's position with the firm. The decision and its reasons should be documented and shared with the home regulator.

Regulator correspondence

The opinion is addressed to national regulators, which will assess how each CASP applies it. A CASP should not wait to be asked. A short written plan to the home regulator, covering the token inventory, the controls, the client timetable and the residual services period, shows the firm has acted. Progress updates up to 8 January 2027 complete the record.

Firms with an application in progress should expect questions on stablecoin policy as part of the assessment. Our EU MiCA CASP licence page explains the authorisation itself, and our MiCA compliance guide for CASPs covers ongoing duties.

After 8 January 2027

From 8 January 2027, a CASP that still offers non-compliant stablecoins to EU clients beyond the residual services ESMA describes is outside ESMA's expectations, and its home regulator will assess that position. Each new stablecoin should go through the register check before listing. Firms that handle custody or transfers of e-money tokens for clients should also confirm they hold a payment services licence or use a licensed partner, which has been required since 2 March 2026.

Firms serving both the EU and the UK face a second regime with different stablecoin rules. Our comparison of MiCA and the UK cryptoasset regime sets out the differences, and our compliance support team runs stablecoin remediation programmes alongside ongoing MiCA compliance.
