Anyone holding Tether on a European exchange now has a date to watch. On 8 October ESMA, the EU’s securities and markets authority, published an opinion addressed to national regulators: authorised crypto platforms must stop offering services around stablecoins that don’t comply with MiCA, the bloc’s crypto-asset regulation. Customer positions should be resolved “as soon as possible, and no later than three months,” which CoinDesk puts at 8 January 2027.
The document names no tokens. CoinDesk cites Tether’s USDT, the largest stablecoin by market value, as the obvious example of an unauthorised coin, and adds that PayPal USD, the third largest, isn’t authorised either. During the wind-down platforms may still let customers sell, convert, withdraw, transfer or safekeep the tokens, but not buy, promote or trade them. ESMA’s reasoning is that keeping non-compliant stablecoins available through authorised platforms would weaken the rules on reserves, redemption, governance and disclosure that compliant issuers must follow.
The timeline helps place the moment. MiCA’s stablecoin rules have applied since June 2024, and the full regime for crypto platforms took effect on 1 July 2026. For ordinary users the practical outcome depends on each platform: some will let people sell or withdraw for a while, others may cut off sooner. Anyone affected should follow their exchange’s instructions.
The second chapter came on 9 October. According to CoinAlertNews, EU finance ministers reached a political agreement to give ESMA direct supervision of the largest crypto-asset service providers. Covered firms would be those with at least 15 million active EU users, or meeting three of five further criteria: over a million active users, more than €1 billion in assets under custody, over €4 billion in annual client transactions. Officials reportedly expect only 10 to 15 of about 360 providers to qualify, narrower than the European Commission wanted. The Council’s position still has to be negotiated with the European Parliament before it becomes law.
The problem it aims at is passporting: a firm authorised in one member state can serve the whole EU, mostly under home-country supervision. In July 2025 ESMA found insufficient evidence that Malta’s regulator had properly assessed one provider’s authorisation, and Malta opposes moving the powers.
The side effects the article lists are predictable: fragmented liquidity, friction in conversions, activity drifting to venues outside the EU, a push towards authorised stablecoins such as USDC, and doubt over whether euro stablecoins issued in the EU can compete globally. Neither source says it will play out that way; both describe risks, not outcomes.
A note on method: the 15-million-user threshold and the criteria count come from a single source (CoinAlertNews), and ESMA’s opinion, as relayed by CoinDesk and TokenPost, was not read here in its original text. For people living in the Canaries who use EU-authorised platforms, the rule applies as it does to any European resident; no measure specific to the archipelago has been reported.
