ESMA Pushes Stablecoin Wind-Down Under MiCA

European securities regulator ESMA has told national supervisors to ensure MiCA-authorized crypto platforms stop providing normal services involving stablecoins that do not satisfy the regulation’s requirements. In its October 8 opinion, ESMA said crypto-asset service providers should no longer maintain, introduce or facilitate client access to non-MiCA-compliant asset-referenced tokens and e-money tokens in the European Union. The supervisory position covers trading, exchange, execution, transfers, custody, investment advice and other services regulated under MiCA.

The opinion does not require existing holdings to disappear immediately. National Competent Authorities may permit limited services necessary for an orderly wind-down, including conversion, withdrawal, transfer and other exit functions. Remaining pre-existing exposures must be remediated as soon as possible and no later than three months after the October 8 publication, placing ESMA’s outer supervisory deadline on January 8, 2027.

Coinbase Sets an Earlier EEA Deadline

Coinbase adopted a faster timetable for retail customers across the European Economic Area. The exchange gave affected users until October 30 to withdraw 14 assets it classifies for this purpose as non-MiCA-compliant EMTs or ARTs: USDT, PAX, PYUSD, GUSD, GYEN, DAI, BUST, UST, RAI, PAXG, MUSD, USD1, USDS and TGBP. Buying, selling and converting those assets had already been restricted, leaving withdrawal as the route for customers who wanted to continue holding them outside Coinbase.

That October 30 deadline has now passed. Coinbase says balances remaining on the cutoff date were subject to a one-time conversion at the prevailing market rate, primarily into USDC where suitable or another supported crypto asset or currency where necessary. The exchange’s documentation establishes the conversion policy but does not provide a platform-wide confirmation that processing has finished for every affected retail account. The restriction applies to Coinbase’s EEA retail service through its MiCA-authorized Luxembourg entity.

Post-deadline deposits face a different treatment. Coinbase warns that newly received restricted assets will not be credited to customer balances, cannot be traded or transferred through the account and are excluded from the automatic conversion process. Recovery may be attempted through the exchange’s unsupported-asset recovery system where technically possible, but Coinbase explicitly says recovery is not available for every asset or network and is not guaranteed.

MiCA Moves From Issuer Rules to Platform Access

ESMA’s October opinion sharpens an important part of MiCA enforcement. The regulation already establishes requirements for issuers of ARTs and EMTs, but ESMA is now emphasizing that authorized CASPs should not provide normal distribution and service infrastructure around tokens that fail those requirements. The practical consequence is that regulatory status increasingly determines whether a stablecoin can remain accessible through licensed European trading, custody and transfer services.

That transition is already visible across platforms. Revolut has moved to phase out USDT access for eligible European customers, while OKX Europe has limited USDT to a one-way conversion route into USDC. At the same time, compliant alternatives are moving deeper into the regulated framework, with USDC recently designated the EU’s first significant e-money token under MiCA. These are separate platform and supervisory decisions, but together they show how MiCA is reshaping distribution rather than preventing users from possessing every affected token in self-custody.

Coinbase also says the stablecoin-issuer transitional period relevant to its service ended on July 1, 2026 and was not extended. Its October 30 action therefore represents its own implementation of those regulatory obligations, while ESMA’s newer opinion establishes a broader supervisory expectation for MiCA-authorized CASPs. The key distinction is between an EU-wide supervisory wind-down ending no later than January 8, 2027 and individual platforms choosing earlier operational deadlines for their customers.
