The European Securities and Markets Authority has ordered MiCA-licensed crypto firms to halt services for non-compliant stablecoins by January 8, 2027, according to an opinion the regulator issued on October 8, 2026.

Tether's USDT is the most prominent casualty. The directive triggers a three-month supervised wind-down that, in practice, codifies restrictions already active across major European exchanges.

What did ESMA actually order?

The opinion covers crypto-asset service providers (CASPs) authorized under the EU's Markets in Crypto-Assets framework — the licensed exchanges, brokers and custodians now operating across all 27 member states.

ESMA singled out two token categories: e-money tokens, which are stablecoins pegged to a single currency, and asset-referenced tokens, which track a basket of assets. Stablecoins failing MiCA's authorization tests fall under the order.

After publication, CASPs had to stop new trading in non-compliant stablecoins immediately and prevent clients from increasing positions.

Why did USDT fall outside MiCA?

MiCA's licensing transition for CASPs closed on July 1, 2026. From that date, only compliant stablecoins could continue operating on licensed EU venues.

Tether never applied for e-money token authorization for USDT. The company weighed MiCA's reserve rules and concluded one stipulation — a requirement that at least 60% of reserves sit in European bank deposits — was commercially untenable for its reserve model.

That choice cascaded through regional trading venues. Coinbase and Binance moved to restrict USDT for users in the European Economic Area as mid-2026 approached. Revolut completed its own phase-out by August 31, 2026.

Which stablecoins cleared MiCA?

Circle's USDC and EURC met the framework's standards and remain available on licensed EU platforms, preserving regulated options for both dollar and euro-denominated exposure.

During the wind-down, firms can still offer a limited service menu to clients holding non-compliant tokens:

• Sell-only orders
• Conversions into other assets
• Withdrawals and transfers
• Safekeeping of existing balances

What changes for traders?

Individual holders are not being told to liquidate USDT. The restrictions apply to services provided by MiCA-licensed firms, not to private ownership, so users can still transact via self-custody wallets or unregulated venues.

EU residents holding USDT on a licensed platform must decide whether to sell, convert or withdraw before the cutoff. Users who wait past the deadline will find fiat ramps, custody and trading unavailable through licensed intermediaries.

What does this mean for Tether?

The order cedes a major regulated corridor. The token continues to dominate trading volume across Latin America, Africa and parts of Asia, so the company's overall reach is unaffected.

The episode sharpens a structural question for stablecoin issuers: reserve composition and jurisdictional access are now directly linked. Firms optimizing reserves for yield may find fewer compliant entry points inside the EU.

National regulators will apply ESMA's framework to CASPs that miss the deadline, with the opinion supplying the formal enforcement basis.

By January 8, 2027, every licensed venue serving EU clients must have completed its migration off non-compliant stablecoins.
