What is MiCA and how does it affect stablecoins?
MiCA, the EU's Markets in Crypto-Assets regulation, imposed licensing, reserve and reporting requirements on 'e-money tokens' and 'asset-referenced tokens' starting June 2024, with enforcement tightening through 2025. Tether's USDT was dropped by several major EU exchanges in 2024-2025 for non-compliance, while Circle's USDC and EURC obtained e-money institution licensing to remain listed.
What MiCA actually requires
MiCA splits significant stablecoins into two categories: e-money tokens (EMTs), pegged to a single fiat currency like the dollar or euro, and asset-referenced tokens (ARTs), pegged to a basket or other assets. Issuers of either must be authorised as an e-money institution or credit institution in the EU, hold reserves that are safeguarded and largely liquid, provide redemption rights at par, and meet ongoing reporting and governance requirements — a materially higher bar than most issuers previously faced anywhere.
Why USDT got dropped from EU venues
Tether did not seek an EU e-money licence for USDT, and several major exchanges — including Coinbase, Crypto.com and others — removed USDT trading pairs for EU customers through 2024 and 2025 to comply with MiCA. This didn't make USDT illegal to hold, but it cut off regulated EU exchange access, pushing EU users toward compliant alternatives or offshore/DEX venues.
Who complied, and the trade-off
Circle obtained e-money institution authorisation in France for USDC and EURC, positioning them as the compliant default for EU-facing platforms. The trade-off issuers face is real: MiCA's reserve rules require a meaningful share of reserves in EU bank deposits, which reintroduces exactly the kind of single-jurisdiction banking concentration risk that caused USDC's March 2023 depeg, just now mandated by regulation rather than chosen voluntarily.
- EMTs: single-currency pegged tokens like USDC, USDT, EURC
- ARTs: multi-asset or basket-referenced tokens, a smaller category
- Non-compliant issuers: delisted from EU-regulated exchanges, not banned outright for individuals
- Reserve requirement: significant EU bank deposit component mandated for large EMTs
Frequently asked
- Is USDT illegal in the EU now?
- No, holding it isn't illegal, but MiCA-compliant EU exchanges have removed it from trading pairs since Tether hasn't obtained the required e-money licence.
- Which stablecoins are MiCA compliant?
- USDC and EURC, via Circle's French e-money institution licence, are among the clearest compliant examples; other issuers have pursued similar licensing since.
- When did MiCA's stablecoin rules take effect?
- The stablecoin-specific provisions (Titles III and IV) applied from 30 June 2024, ahead of the broader crypto-asset service provider rules later that year.
- Does MiCA require stablecoin reserves to be EU-based?
- It requires a significant proportion of reserves for large EMTs to be held with EU credit institutions, which concentrates banking risk within the EU by design.
