MiCA (EU Markets in Crypto-Assets)
Also called: MiCA · MiCAR · Markets in Crypto-Assets Regulation
Definition
MiCA (Markets in Crypto-Assets) is the European Union regulation that sets common rules for crypto-asset issuers, stablecoins and crypto service providers across all EU member states.
How MiCA works
MiCA creates one rulebook for the EU instead of 27 national regimes. Its stablecoin rules for e-money tokens and asset-referenced tokens applied from 30 June 2024. Its rules for crypto-asset service providers, called CASPs, applied from 30 December 2024, with national transition periods that can run up to 1 July 2026.
A CASP licensed in one EU country can passport its services to the others. Licensed firms must meet requirements on governance, capital, custody and safekeeping of client assets, conflicts of interest and clear disclosures. Token issuers must publish a white paper with prescribed information.
For users, the visible effects include exchanges restricting or delisting stablecoins that are not MiCA-compliant for EU customers, more detailed onboarding, and clearer complaint procedures. MiCA does not cover everything: most fully decentralized services and NFTs fall largely outside it, and tax remains national. Check whether the specific entity serving you holds a MiCA licence.
Example
Suppose you live in Spain and use an exchange whose EU entity received a MiCA licence in another member state. Through passporting, it can serve you. You hold 3,000 units of a stablecoin that has no authorised issuer under MiCA. The exchange announces that EU users can no longer buy that coin but can still sell or withdraw it for a period. You could convert the 3,000 units into a MiCA-compliant stablecoin, paying perhaps a 0.1% fee, which would be 3 units.
Common mistakes
- Assuming every exchange operating in the EU is already MiCA licensed while transition periods run.
- Thinking MiCA sets crypto tax rules, which remain the job of each country.
- Treating a MiCA licence as a guarantee that you cannot lose money trading.

FAQ
When did MiCA come into force?
Stablecoin rules applied from 30 June 2024 and service provider rules from 30 December 2024. Some countries allow transition periods up to 1 July 2026 for existing providers.
Why are some stablecoins restricted in the EU?
Under MiCA, stablecoins offered to the public need an authorised issuer. Exchanges therefore limit trading of non-compliant stablecoins for EU customers.
