## Summary

The EU's Markets in Crypto-Assets Regulation (MiCA) is now fully in force across all 27 member states. Crypto asset service providers have completed the authorisation process, stablecoin issuers have obtained e-money licences, and the first enforcement actions are emerging.

The EU's Markets in Crypto-Assets Regulation (MiCA) entered full force in December 2024, with the transition period for crypto asset service providers (CASPs) concluding in June 2025. As of mid-2026, the regulatory landscape in Europe has fundamentally changed: exchanges must hold CASP licences, stablecoin issuers require e-money licences, and regulators in France, Germany, and the Netherlands have begun issuing enforcement notices to non-compliant operators.

MiCA is the world's most comprehensive crypto asset regulatory framework to date, covering issuance of crypto assets (including stablecoins), trading platform operations, custody services, and market abuse prevention — all under a single EU-wide passport framework that allows a licensed operator in one member state to operate across all 27.

## Stablecoin Issuers Under MiCA

MiCA distinguishes between two categories of stablecoins: e-money tokens (EMTs), which are pegged to a single fiat currency, and asset-referenced tokens (ARTs), pegged to a basket of assets. Both require authorisation from a national competent authority.

Circle obtained an e-money licence from the French Autorité de Contrôle Prudentiel et de Résolution (ACPR) in 2024, making it the first major stablecoin issuer fully compliant with MiCA. USDC is now the only major stablecoin issued under a MiCA-compliant structure across the EU.

Tether has not obtained a MiCA e-money licence. Several European exchanges began delisting USDT from EU-accessible platforms ahead of the compliance deadline, though enforcement of this requirement has varied by member state. Tether has publicly stated it is building an EU-compliant entity but has not provided a timeline for obtaining a licence.

## What MiCA Means for DeFi

MiCA's most debated provision for the DeFi sector is Article 2(4), which explicitly excludes 'fully decentralised' crypto asset services from MiCA's scope — but does not define what 'fully decentralised' means in practice. The European Securities and Markets Authority (ESMA) has committed to publishing guidance on this definition, which is expected later in 2026.

Until ESMA publishes its guidance, DeFi protocols with any degree of governance by an identifiable legal entity face regulatory uncertainty about whether they are exempt from or subject to MiCA. Protocols with multisig controllers, foundations, or active governance DAOs are particularly exposed.

For DeFi users in the EU, MiCA's immediate practical impact is primarily on the centralised exchange and custody layer — not on direct protocol interactions. Using Uniswap, Aave, or Curve through a web3 wallet is not regulated activity under MiCA as currently interpreted.

## Compliance Leaders and Laggards

- Compliant: Coinbase (CASP licence, Ireland), Kraken (CASP licence, Ireland and Cyprus), Bitstamp (Luxembourg), Binance (France and Poland — after initial withdrawal and reapplication).
- Circle: USDC is MiCA-compliant under French e-money licence — the only major stablecoin in this position.
- Tether: USDT does not hold an EU e-money licence. Enforcement of exchange delisting requirements remains inconsistent across member states.
- Non-EU exchanges: Several exchanges without EU licences have geofenced EU users and directed them to licenced subsidiaries or third-party white-label solutions.
- DeFi: No major DeFi protocol has been formally regulated under MiCA as of mid-2026. ESMA guidance expected H2 2026.
