If you run a MiCA-authorised crypto-asset service provider (CASP), ESMA has just told you what to do about stablecoins that are not MiCA-compliant: stop serving them to EU clients. On 8 October 2026 the authority published an opinion setting out supervisory expectations for services linked to non-compliant asset-referenced tokens (ARTs) and e-money tokens (EMTs). For a licensing decision, this moves stablecoin support from a commercial choice to a condition of staying on the right side of your national regulator.
The practical consequence is that your token listing policy is now part of your authorisation story. A licence application that lists a broad set of stablecoins without a clear MiCA-status check is harder to defend than one with a tight, documented whitelist.
What does the ESMA opinion on non-MiCA stablecoins require?
ESMA's position, as stated in its news release of 8 October 2026, has four parts:
- MiCA-authorised CASPs should cease providing services related to non-MiCA-compliant stablecoins to EU clients.
- The expectation covers the full range of crypto-asset services, alone or in combination: trading platforms, exchange, order execution and transmission, placing, advice, transfers, custody and administration, and portfolio management.
- National competent authorities should check that firms do not keep, introduce or facilitate client access to these tokens, and that technical, contractual and organisational controls stop clients acquiring or increasing exposure.
- Where existing exposures are found, they should be remediated as soon as possible and no later than three months after publication of the opinion.
Counting three months from 8 October 2026 points to roughly 8 January 2027. Confirm the exact date against the opinion text and your own regulator's guidance.
What continued service is allowed?
During the remediation window, ESMA says any continued service should be strictly limited to liquidation, conversion, withdrawal, transfer or safekeeping of the assets. It also has to be time-limited, risk-based and closely supervised. In other words, clients can leave, but they cannot add.
Who is affected most
Exchanges and custodians with large multi-token order books carry the heaviest remediation load, because every listed stablecoin needs a MiCA-status check and a technical block for new exposure. Advisors and portfolio managers need the same check applied to model portfolios and client mandates.
Issuers are affected indirectly. The EMT route runs through e-money authorisation, so a euro or dollar stablecoin that wants EU distribution needs an authorised issuer behind it. The Netherlands e-money profile and Netherlands crypto profile show how one major EU market handles the two regimes side by side.
What to do this quarter
First, inventory every stablecoin you list, custody or route, and record its MiCA status with a dated source. Second, document the controls that stop new exposure to any token that fails the check. Third, agree your wind-down path for existing client balances with your national competent authority before the three months run out. Finally, if you are choosing where to apply, compare how EU jurisdictions treat stablecoin-related services side by side on the crypto comparison and the e-money comparison.
