USDT is the world's largest stablecoin by supply and the dominant rail for dollar transfers in emerging markets. In Europe, its regulatory status changed sharply in early 2025. Tether — the company behind USDT — has not obtained authorization under the EU's MiCA regulation. The result: as of 31 March 2025, USDT is no longer available for trading on any exchange regulated under MiCA across the 27-member European Economic Area.
This article explains the legal basis for that outcome, which stablecoin has taken USDT's place on EU platforms, and what businesses with European exposure should do.
Why USDT is off European exchange books
MiCA classifies a dollar-pegged stablecoin as an e-money token (EMT) — a digital representation of value that purports to maintain a stable value by referencing a single official currency. Title III of MiCA requires that anyone who offers an EMT to the public in the EU, or seeks its admission to trading on an EU venue, must be authorized as an electronic money institution (EMI) or credit institution in an EU member state.
Tether Limited — incorporated in the British Virgin Islands — has not obtained an EU EMI license, nor has it licensed an EU-incorporated subsidiary to issue USDT under MiCA. Without authorization, no MiCA-regulated exchange may offer USDT for trading to EEA users.
The enforcement deadline for this requirement was 31 March 2025 — the date by which exchanges had to remove unauthorized stablecoins from their trading books (a grace period from the December 2024 full-application date). The main delistings, in chronological order:
| Exchange | Action | Date |
|---|---|---|
| Coinbase Europe | Delisted USDT spot pairs for EEA users | December 2024 |
| Crypto.com | Stopped offering USDT to EU customers | 31 January 2025 |
| Binance | Delisted nine stablecoins including USDT for EEA users | March 2025 |
| Kraken | Placed USDT in sell-only mode from 24 March; fully disabled trading by 31 March 2025 | March 2025 |
The pattern was consistent: regulated EU exchanges determined that continuing to offer USDT exposed them to regulatory risk under their MiCA CASP licenses and acted before the enforcement deadline.
What ESMA said about custody and transfers
Importantly, MiCA does not prohibit holding or transferring USDT. ESMA — the European Securities and Markets Authority — clarified in a January 2025 statement that custody and transfer services for unauthorized stablecoins "do not in themselves constitute an 'offering to the public' or 'seeking admission to trading.'" Custodians, wallet providers, and settlement systems can continue to handle USDT for existing holders without breaching MiCA. The restriction is on exchange trading and new public offerings, not on peer-to-peer transfers or custody of tokens already held.
USDC's MiCA authorization and EU market position
Circle moved early and fast. It obtained EMI authorization from France's Autorité de Contrôle Prudentiel et de Résolution (ACPR) in July 2024 — before MiCA's stablecoin rules even fully applied — making it the first global stablecoin issuer to be MiCA-compliant. USDC is issued in the EU by Circle Mint Europe SAS, and the French EMI license carries an EU passport, valid across all 27 member states.
Circle's USDC reserves in the EU are held primarily in short-dated US Treasuries via the Circle Reserve Fund (managed by BlackRock), with the cash portion in custodian banks — structured to satisfy MiCA's requirement that at least 30% of EMT reserves sit in segregated bank accounts.
By mid-2025, USDC market capitalization had passed $50 billion globally, with the EU portion estimated at roughly $8–10 billion in transaction-flow analysis. On major EU regulated exchanges, USDC has become the default dollar-denominated trading pair where USDT previously dominated.
The MiCA-authorized stablecoin landscape in mid-2026
The authorized list as of this writing is short but expanding:
| Stablecoin | Issuer | Authorization | Currency |
|---|---|---|---|
| USDC | Circle Mint Europe SAS | French ACPR EMI | USD |
| EURC | Circle Mint Europe SAS | French ACPR EMI | EUR |
| EURI | iFinex / Banking Circle | Luxembourg | EUR |
| EURCV | Société Générale — Forge | French ACPR | EUR |
| EURAU | AllUnity | BaFin (Germany) EMI | EUR |
This list is not exhaustive — several smaller regional EMTs from European banks and e-money institutions hold authorization — but it illustrates how concentrated the authorized market remains around a small number of issuers, particularly Circle.
What this means for your business
The MiCA/USDT situation has practical implications depending on how your business uses stablecoins in or toward Europe.
If you use USDT for European settlement with regulated counterparties: Flows that pass through MiCA-regulated CASPs — exchanges, custodians, payment processors licensed in the EU — cannot use USDT for trading or new purchases. If your settlement process involves any MiCA-regulated intermediary on the EU side, you need a MiCA-authorized stablecoin.
If you pay European employees or contractors in stablecoins: Payroll flows in USD stablecoins directed to EU recipients who convert through EU-regulated platforms will encounter the USDT restriction. USDC is the primary drop-in replacement for dollar-denominated payroll in the EU today.
If you are building a stablecoin product for EU users: Any product that involves "offering" an EMT to EU users or seeking its listing on an EU venue requires either issuer authorization under MiCA or use of an already-authorized token. Launching with an unauthorized stablecoin is not a viable path if you intend to use EU-regulated infrastructure.
If you hold USDT as treasury: Existing USDT holdings can be custodied and transferred. The practical risk is exit: converting USDT to euros or another currency through a regulated EU exchange is not currently possible via spot trading. Over-the-counter routes and non-EEA exchanges remain accessible for holders who need to liquidate.
If you operate in the EU as a CASP: Your license requires compliance with the stablecoin provisions of MiCA. Continuing to offer unauthorized stablecoins after the 31 March 2025 deadline exposes your license to supervisory action.
Tether's position and what might change
Tether has been publicly skeptical of MiCA's EMT requirements, particularly the 30%-in-bank-deposits reserve rule and the operational burden of obtaining and maintaining an EU EMI license. As of mid-2026, Tether has not announced a change in approach toward MiCA authorization for USDT. Whether that changes depends on Tether's commercial assessment of the EU market relative to the compliance cost — a calculation complicated by the 30% bank-deposit requirement, which is stricter than what Tether currently maintains globally.
If Tether were to obtain MiCA authorization in the future, it would likely require establishing a licensed EU entity, restructuring a portion of reserves into EU bank deposits, and publishing disclosures aligned with EBA regulatory technical standards.
The bottom line
MiCA has reorganized the European stablecoin market in a matter of months. The framework is clear: unauthorized stablecoins cannot be traded on regulated EU exchanges. USDC has filled the gap as the primary MiCA-authorized dollar stablecoin, and the list of authorized euro stablecoins is growing. For businesses operating in Europe — whether for payments, payroll, settlement, or product development — the compliance question is now a practical operational one.
