Europe’s ambitious new regulatory framework for crypto assets, the Markets in Crypto Assets (MiCA) regulation, took effect on July 1, marking a new era for digital finance across the European Union. The implementation has already brought dramatic changes, as regulated crypto exchanges quickly began delisting Tether’s USDT stablecoin from their platforms. Amid this shakeup, Circle has emerged as a standout player, swiftly filling the gap with its own compliant stablecoin offerings.
Circle adapts, Tether retreats
Anticipating MiCA’s requirements, Circle proactively aligned its dollar-pegged USDC and euro-backed EURC stablecoins to meet the regulation’s new standards. Among the world’s ten largest stablecoins, Circle became the only issuer able to fully comply with MiCA’s conditions. Headquartered in the United States, Circle remains a heavyweight in the stablecoin market, with USDC ranking among the largest by market value.
In stark contrast, Tether chose not to apply for the electronic money issuance license mandated under MiCA. The consequence: roughly $185 billion worth of USDT is now inaccessible on licensed European trading venues, forcing a radical overhaul of liquidity structures across the region’s regulated crypto platforms.
Tether’s management has voiced strong objections to MiCA’s requirement that 60% of stablecoin reserves be held in European banks, highlighting what they see as additional risks. As a result, Tether is shifting its strategic focus away from Europe to markets outside the EU.
Tether CEO Paolo Ardoino publicly defended the company’s decision, warning that altering their reserve model to match European standards would introduce new risks. Rather than overhauling its structure, Tether has opted to double down on its established approach in non-European markets, stepping back from the bloc for now.
Institutional backing gives Circle momentum
Circle’s position received a major boost in timing and legitimacy. On the very eve of MiCA’s rollout, banking giant BNY Mellon announced support for USDC. This move enables institutional clients to store, transfer, issue, and burn USDC through BNY Mellon’s network—an endorsement carrying significant weight from one of the world’s largest custodians.
Glossary: CASP refers to the “Crypto Asset Service Provider” license under MiCA. This license authorizes regulated custody, trading, and transfer services for crypto assets throughout the EU.
BNY Mellon’s timely move, coinciding with changes on European exchanges, has bolstered Circle’s position on both the regulatory and institutional fronts. This shift is not only about stablecoin rivalry but also about which issuers will shape the European market in the long term.
MiCA reshapes more than just stablecoins
The MiCA regulation has brought sweeping consequences beyond just USDT and USDC. Out of nearly 1,200 crypto companies previously registered at the national level, only about 210 have managed to secure full-scope CASP authorization under the new law—a success rate of approximately 17%.
| Category | Status |
|---|---|
| Number of firms registered before MiCA | Approximately 1,200 |
| Companies awarded full CASP license | Approximately 210 |
| Percentage | 17% |
With USDT liquidity now unavailable at regulated European platforms, Circle’s long-standing regulatory strategy positions it to capture market share rapidly.
This landscape demonstrates that the ripple effects go beyond regulatory compliance. While Circle invested years in preparation, Tether has essentially ceded the European field for now. Although Tether may yet seek EU licensing in the future, there is no clear indication of such plans at present.
