MiCA (Markets in Crypto-Assets Regulation) is the EU's first comprehensive crypto law, passed in 2023 with staggered enforcement through 2024–2025. Here's how it works at a high level (general regulatory knowledge, not live data):
What it covers
- Crypto-asset service providers (CASPs) — exchanges, custodians, brokers, and similar firms now need a license (MiCA authorization) in one EU member state, which is then recognized across all 27 (the "passport"). No license, no serving EU customers.
- Three token buckets, three rulebooks:
- Asset-referenced tokens (ARTs) — tokens pegged to a basket of assets/currencies (e.g. some stablecoins). Strictest rules: reserve requirements, daily reporting, and a cap on transaction volume for big ones used as a means of payment.
- E-money tokens (EMTs) — tokens pegged to a single fiat currency (the classic stablecoin). Treated essentially like electronic money; issuer must be a credit institution or e-money institution, hold reserves 1:1, and let holders redeem at par at any time.
- Utility tokens & others — lighter disclosure duties (a white paper registered with regulators) rather than the heavy stablecoin regime.
- White papers — most issuers must publish a crypto white paper (plain-language, standardized disclosures), analogous to a securities prospectus but lighter.
Key themes and consequences
- Stablecoin squeeze: non-EU stablecoins that don't comply effectively lose EU listings — this is exactly why major issuers restricted or relabeled products for EU users in 2024–25. USDT's status in the EU has been an ongoing point of tension.
- Investor protection over innovation: heavy emphasis on transparency, disclosure, and custody rules — arguably at the cost of making small launches more expensive.
- Out of scope: MiCA deliberately excludes assets that already count as financial instruments/securities (those stay under existing EU securities law), NFTs generally (unless they functionally resemble tokens), and pure DeFi protocols that are genuinely decentralized.
Honest caveats
- Implementation is still maturing — actual enforcement practice, the ESMA/EBA technical standards, and how aggressively authorities apply the DeFi carve-out are still being worked out.
- The data above is background knowledge, not something I verified live this turn.
