Circle’s MiCA approval has turned Europe’s stablecoin deadline into a market opening as licensed exchanges remove Tether USDT (USDT).
Key Points:
- Circle enters MiCA’s full phase with USDC and EURC cleared for regulated European venues.
- Tether did not seek the e-money-token authorization required under MiCA.
- The next test is whether EU trading volume moves from USDT to USDC in size.
Circle USDC
Circle entered Jul. 1 with a clear advantage as the European Union’s Markets in Crypto-Assets regulation reached its final deadline and licensed exchanges began removing USDT from their platforms.
The divide reflects two different regulatory bets. One issuer spent years preparing for MiCA, while the other decided Europe was not worth the compliance cost.
Circle secured MiCA compliance for USD Coin (USDC) and EURC (EURC), making it the only issuer among the top 10 stablecoins by market value to clear that standard.
Tether did not apply for the e-money-token authorization MiCA requires, leaving its roughly $185 billion USDT outside licensed European exchanges. Paolo Ardoino, Tether’s CEO, has argued that MiCA’s rule requiring 60% of e-money token reserves to sit in European bank deposits creates risk of its own.
Rather than change its reserve structure for Europe, Tether has focused on markets outside the bloc.

Stablecoin Market
Circle’s timing also improved outside Europe. BNY, the Bank of New York Mellon, confirmed one day before the deadline that USDC became the first stablecoin on its Digital Asset Custody platform, where institutional clients can store, transfer, mint and burn the token.
The broader MiCA transition shows how narrow the new market has become. About 1,200 virtual-asset firms held pre-MiCA national registrations across the EU, but only around 210 moved to full CASP authorization, a conversion rate near 17%.
For Circle, the business question now matters more than the legal milestone. Regulated venues can no longer rely on USDT liquidity, and Circle is positioned to capture flows that need a compliant dollar stablecoin.
Stablecoin liquidity in Europe had long depended on USDT because traders used it as the default bridge between crypto assets and dollars. The next few weeks will show whether that habit survives MiCA, or whether volume shifts toward USDC in regulated markets.
