ESMA Stablecoin Opinion for MiCA Crypto Firms
The European Securities and Markets Authority (ESMA) has told crypto-asset service providers (CASPs), such as exchanges, brokers and custodians, authorised under the Markets in Crypto-Assets Regulation (MiCA, the EU crypto rulebook) to stop providing services related to stablecoins that do not comply with MiCA. ESMA published the opinion on 8 October 2026. It is ESMA’s formal view on how the rules should apply, a supervisory expectation rather than a new law.
The expectation covers two kinds of stablecoin: asset-referenced tokens (ARTs, backed by a basket of assets) and e-money tokens (EMTs, pegged to a single official currency). It applies to clients in the European Union and to every MiCA service, alone or in combination: operating a trading platform, exchange services, executing orders, placing crypto-assets, receiving and transmitting orders, investment advice, transfers, custody and administration, and portfolio management. A firm cannot keep a non-compliant token by moving it from one service line to another.
ESMA asks national competent authorities, the national regulators that supervise firms, to check that CASPs neither maintain, introduce nor facilitate client access to non-compliant stablecoins. Regulators should also ensure firms run technical, contractual and organisational controls that keep such tokens unavailable in the EU, including controls that stop clients buying them or increasing their exposure. The opinion is therefore aimed at MiCA-authorised CASPs serving EU clients, and the supervisory work falls to each firm’s own national regulator.
Where regulators find existing exposures, they should require the firm to fix them as soon as possible and no later than three months after publication. Three months from 8 October 2026 puts the limit at 8 January 2027, by LeapRate’s calculation. Until then, any continued service should be strictly limited to what is needed for liquidation, conversion, withdrawal, transfer or safekeeping, and stay time-limited, risk-based and closely supervised.
| Requirement | What changes |
|---|---|
| Who is addressed | MiCA-authorised CASPs, with national competent authorities asked to supervise them |
| Core expectation | Cease services related to non-MiCA-compliant ARTs and EMTs for EU clients |
| Services covered | All MiCA services, alone or combined |
| Controls | Technical, contractual and organisational controls stopping clients acquiring or increasing exposure |
| Existing positions | Remedy as soon as possible, no later than three months after publication (8 January 2027, our calculation) |
| Interim activity | Only liquidation, conversion, withdrawal, transfer or safekeeping; time-limited, risk-based, closely supervised |
In practice, the expectation implies that a firm still listing or holding a non-compliant stablecoin should stop new purchases and increases in exposure, and plan the wind-down of existing positions before the three-month limit.
