The European Securities and Markets Authority (ESMA) told national regulators on 8 October 2026 that crypto firms licensed under MiCA should stop offering EU clients any service linked to stablecoins that do not comply with the regulation. Existing client positions must be dealt with within three months, which sets an outer limit of 8 January 2027. The aim is to close the gap that let licensed platforms keep handling unauthorised tokens after MiCA’s transition period ended.
What ESMA’s stablecoin opinion says
The guidance takes the form of an opinion addressed to national competent authorities. It covers asset-referenced tokens (ARTs) and e-money tokens (EMTs), the two stablecoin categories defined by MiCA, when the conditions for a lawful public offer or admission to trading in the EU are not met.
According to ESMA’s press release, authorised crypto-asset service providers “should cease providing services related to non-MiCA-compliant stablecoins to clients in the European Union”. The expectation applies to every MiCA service, alone or combined:
- operating a trading platform, exchange against funds or other crypto-assets, and order execution;
- placing, reception and transmission of orders, and investment advice;
- transfers, custody and administration, and portfolio management.
Supervisors are asked to make sure firms do not maintain, introduce or facilitate client access to these tokens, and that they have technical, contractual and organisational controls preventing clients from buying more or increasing their exposure.
The three-month timeline and the exit services
Where supervisors find existing exposures, they should require firms to resolve them “as soon as possible” and no later than three months after publication. Cointelegraph reports that this outer limit falls on 8 January 2027 and that national authorities may set earlier dates.
Firms may keep only the services a client needs to leave a position: liquidation, conversion, withdrawal, transfer or safekeeping. ESMA says these must be time-limited, risk-based and closely supervised. This is a tightening: earlier guidance from January 2025 had allowed custody and transfers of non-compliant stablecoins to continue, as Cointelegraph notes.
Which tokens are concerned?
ESMA does not name any token. The test is whether the issuer meets MiCA’s rules for ARTs and EMTs. Exchanges draw their own lists: Cointelegraph reports that Coinbase identified Tether’s USDT and PayPal’s PYUSD as non-compliant, told customers in the European Economic Area to withdraw affected balances by 30 October 2026, and said remaining balances would be converted into USDC or another supported asset.
For Tether (USDT), the largest stablecoin by supply, this extends a trend that began in late 2024 and early 2025, when major platforms restricted USDT trading for European customers. The opinion goes further by reaching custody and transfers as well.
Context: a stricter MiCA in preparation
The opinion follows ESMA’s response of 30 September 2026 to the European Commission’s consultation on the MiCA review. In it, ESMA asked for an explicit rule in the regulation barring licensed firms from services linked to non-compliant stablecoins, stronger powers against unauthorised third-country firms, and new tools such as the power to block fraudulent websites.
An opinion is supervisory guidance, not a new law. Its reach depends on how each national authority applies it, so timing can differ from one country to another. For the basics of the framework, read our guide to the MiCA regulation.
What it means for EU crypto users
The opinion targets licensed service providers, not individuals. It does not deal with tokens kept in a self-custody wallet. In practice, if you hold a non-compliant stablecoin on an EU platform, expect messages from that platform before January, and possibly earlier. The usual options are to convert the balance into a compliant stablecoin or into euros, or to withdraw it to a wallet you control. Each choice has costs and risks: network fees, conversion spreads, and the responsibility of keeping your own keys safe.
Be wary of messages that urge you to “migrate” stablecoins through a link or ask for your seed phrase. Platforms announce such changes in their app and on their official website. This article is information, not investment advice.
What to watch next
- Notices from national regulators, which may set deadlines earlier than 8 January 2027.
- Delisting and conversion schedules published by EU exchanges and brokers.
- The Commission’s MiCA review proposal, which could turn ESMA’s expectation into a binding rule.
- Any move by issuers of affected tokens to seek MiCA authorisation.
