ESMA gives EU crypto platforms three months to wind down non-MiCA stablecoins
The European Securities and Markets Authority (ESMA) said in an opinion issued Oct. 8 that authorized crypto platforms should stop offering services that let EU customers buy, trade or grow holdings of stablecoins that are not authorized under MiCA, and that any customer balances still standing must be settled within three months.
ESMA calls stablecoins asset-referenced tokens (ARTs) and e-money tokens (EMTs), and the opinion names no specific token. In practice the ruling lands on the largest one: Tether’s USDT, the biggest stablecoin by market capitalization, is not MiCA-authorized, and neither is PayPal USD (PYUSD), the third-largest. MiCA’s stablecoin rules have applied since June 2024, and the full platform rules took effect July 1, forcing firms without authorization to stop serving EU clients.
What changes for the reader is simple. EU users who hold USDT or another non-compliant stablecoin on a regulated platform now face a forced exit, and the options during the wind-down are narrow. “ESMA considers that CASPs should not provide crypto-asset services in relation to ARTs or EMTs that are not compliant with the applicable requirements under MiCA (non-MiCA compliant ARTs or EMTs),” the regulator said.
The wind-down has an asymmetry worth knowing. Platforms may still let customers sell, convert, withdraw, transfer or safekeep the tokens while they exit, but purchases, promotion and continued trading are off the table. The covered services run across the exchange stack: trade execution, transfers, custody, administration, advice and portfolio management.
What each user actually experiences will depend on where they live. National regulators implement the opinion platform by platform, so one venue may wind balances down early while another runs to the wire. Several platforms had already restricted USDT for European users before this opinion, so some readers will find their on-ramp was already closed.
The opinion argues its own logic: ESMA said keeping noncompliant stablecoins available through authorized venues would weaken the reserve, redemption, governance and disclosure rules MiCA places on authorized issuers. An ESMA opinion is guidance to national regulators rather than binding law, but the direction of travel is not in doubt. Balances on EU-regulated platforms are due to be settled, in the regulator’s words, “as soon as possible, and no later than three months,” which puts the deadline at Jan. 8, 2027.
