USDT or USDC: the key points before the October 30 deadline

This much is documented: since October 14, 2026 USDC has carried the status "significant" as the EU's first e-money token, the European Banking Authority EBA takes over direct supervision of the issuer's own funds, reserve and redemption plans on November 12, 2026, and for USDT Tether holds no authorisation as an e-money token under the EU's MiCA regulation. If your balance sits with a provider holding an EU licence, you can therefore continue to buy, swap and redeem USDC unchanged, while USDT drops out of the offering there. Our assessment follows further down: for a portfolio in Germany, a stablecoin's authorisation now weighs more heavily than its market size.

The relative sizes point the other way from the supervisory law. On October 22, 2026 USDT came to around $183 billion in market value and USDC to around $72 billion; the older token is thus roughly two and a half times the weight of the authorised one. Our comparison of the two stablecoins for EU investors dates from December 2024, when this question was still purely a matter of reserves and trust. Since the stablecoin part of MiCA has been in application, authorisation decides first and everything else after.

USDT or USDC: what happens in the European Economic Area on October 30, 2026

Coinbase has set a cut-off date for customers in the European Economic Area. Until October 30, 2026, balances in the affected stablecoins can be withdrawn or swapped by the customer. Whatever is still in the account after that, the exchange converts at the market rate, primarily into USDC and, where USDC does not fit, into another supported asset. According to the exchange's help page on stablecoins that are not MiCA-compliant, those affected include USDT, DAI, PYUSD, PAX, GUSD, GYEN, USD1, USDS and PAXG; buying, selling and swapping these tokens is already restricted for customers in the Economic Area.

Behind the cut-off date stands a European requirement. Licensed crypto service providers may no longer offer tokens without MiCA authorisation freely in the EU; what remains are wind-down services. How the changeover works in detail and which balances it covers, we set out in our report on the conversion of USDT and DAI by October 30. The exchange itself calls the conversion a step towards complying with the regulation and expressly flags withdrawal before the date as the route alongside it.

Other houses set their own dates, and they can fall earlier. For the choice between the two tokens that means the timing is often not set by the holder but by the provider where the balance sits.

E-money tokens under MiCA: why USDC is authorised in the EU and USDT is not

MiCA is the EU regulation on markets in crypto-assets. Its part on value-stable tokens has been in application since June 30, 2024, and the regulation distinguishes two kinds there. An e-money token, EMT for short, references a single official currency, such as the dollar or the euro. An asset-referenced token, ART for short, references a basket of several values. For both kinds the issuer needs an authorisation in the Union.

Within the EU, USDC is issued by Circle Internet Financial Europe SAS, an e-money institution authorised in France; that makes USDC an authorised e-money token. Tether holds no such authorisation for USDT, and the token does not appear in the European register of authorised issuers. The obligations an authorisation triggers are collected in our overview of the MiCA licensing duties for crypto companies.

The difference is no formality. An authorisation obliges the issuer to hold a backed reserve, to maintain own funds, to have a redemption plan and to submit to ongoing supervision by a designated authority. A token without authorisation can function technically without fault and still drop out of the regulated offering, because the provider's obligations govern distribution and not the properties of the token.

Redemption at par: the core right behind an authorised stablecoin

Article 49 of the MiCA regulation gives holders of an e-money token a claim against the issuer. The token is issued at the par value of the funds received and redeemed at par at any time on request, free of charge. A euro in, a euro out: that right distinguishes an authorised stablecoin from a token that is worth only roughly a dollar on the market.

Article 50 additionally prohibits any interest. Neither the issuer nor a crypto service provider may grant remuneration amounting to interest. Recital 68 of the regulation justifies this on the grounds that e-money tokens are meant to serve payments and not the storage of value. A running yield on a stablecoin balance is therefore not something the token itself offers in the EU.

In practice the redemption right works only against the issuer, and only where the issuer accepts customers. A balance in a self-managed wallet is untouched by it; if you bought the token through an exchange, the way back usually runs through the same exchange. The fewer authorised providers that carry a token, the longer that way becomes, and precisely there lies the disadvantage of a token without authorisation for a holder in the EU.

USDC under direct EBA supervision from November 12, 2026

On October 14, 2026 the EBA classified USDC as the EU's first "significant" e-money token. In the Union 45 e-money tokens are notified, and USDC is the first to reach that threshold. From November 12, 2026 supervision of own funds, reserve, liquidity and recovery and redemption plans moves from the French supervisor ACPR to the EBA. With the ACPR remain management, qualifying holdings, the fit-and-proper assessment of those responsible, outsourcing and conflicts of interest. The EBA has additionally concluded an agreement on cooperation with the New York financial regulator, which supervises Circle in its home market.

The classification follows size: reach many users and high amounts in circulation and you are supervised more strictly under MiCA. It is not a seal of quality, and not a warning either. What changes specifically for holders is in our report on the EBA taking over USDC supervision. For holders nothing changes about the token; what changes is the authority behind the redemption promise.

The ESMA deadline of January 8, 2027 and what it does not ban

The European securities regulator ESMA published an opinion on October 8, 2026 that sets January 8, 2027 as the outer limit. By then licensed crypto service providers are to have wound down their remaining holdings and services around stablecoins that are not MiCA-compliant. Covered are e-money tokens and asset-referenced tokens without authorisation, and not in trading alone: the opinion reaches into custody, transfer, order execution, investment advice and portfolio management.

What remains permitted are wind-down services, that is liquidation, conversion, payout, transfer and safekeeping. These services have to be limited in time, calibrated to risk and closely supervised, and they may not be used for new purchases or for marketing. National supervisors can start earlier than January 8, 2027, and that is exactly what explains individual providers' cut-off dates as early as October.

Two points are missing from many summaries. First, the opinion names no individual token; that USDT and PYUSD are meant is a conclusion drawn from the authorisation status and not a statement by the authority. Second, the text is addressed to the national supervisors and through them to the service providers, not to private holders. Nobody in the EU bans a USDT balance in a self-managed wallet. What falls away is the convenient route through licensed providers, and with it the option of buying more there.

Legally the opinion rests on the duty to act in the best interests of clients. On that reading, offering a token without authorisation breaches that duty. No new prohibition is contained in it, which is why implementation hangs on the national authorities, who can move at different speeds.

Reserves compared: government paper at USDC, gold and Bitcoin at Tether

Reserves stand behind both tokens, but they are built differently. Circle holds the USDC reserve predominantly in short-dated US government paper and in repurchase agreements, the rest as bank deposits; the largest part sits in the Circle Reserve Fund, a money market fund registered with the US securities regulator. The attestation reports on it appear monthly and come from Deloitte.

In its report for the second quarter of 2026 Tether shows reserves of around $187.8 billion, with a surplus of $4.11 billion over liabilities. The largest part sits in US Treasury bills, to which are added around ten percent gold and about three percent Bitcoin. According to that report the gold holding was above 146 tonnes and the Bitcoin holding just under 99,000 coins. Attestation is quarterly and comes from BDO. Depending on the reporting date, gold and Bitcoin together account for between about 13 and 14 percent of the reserve, because both items fluctuate in price.

Therein lies the substantive difference for a portfolio. A reserve of short-dated government paper hardly fluctuates in value and can be turned into cash quickly. A reserve with a gold and Bitcoin share hangs on two volatile markets, and the surplus over liabilities shrinks when those markets fall; the report for the second quarter showed exactly that. Both issuers report regularly, one monthly, the other quarterly. Which stablecoins exist besides these two and how they are built is shown in our overview of stablecoins.

An attestation is not a running certificate. An attestation also always depicts a single reporting date and does not describe what happens in the reserve between two dates. For the choice between the tokens the cadence therefore counts too: monthly produces a tighter picture than quarterly.

Tax on a stablecoin swap: holding period and the €1,000 exemption limit

In Germany, swapping one crypto-asset for another counts as a disposal. The move from USDT into USDC therefore falls under private disposals pursuant to Section 23 of the German Income Tax Act. If the token given up was bought less than a year ago, a gain is taxable; since 2024 it stays tax-free only below an exemption limit of €1,000 in the calendar year, and that limit applies to all private disposals of a year taken together. Exceed the limit and the entire gain is taxable.

With a stablecoin the gain is usually small but rarely zero. Between purchase and swap the euro-dollar rate moves, and that alone produces a difference in the euro equivalent. More important is the second consequence: for the USDC received, the one-year period starts again. If you held an old balance whose period had almost run, you stand back at the beginning after the swap.

That makes for a practical difference between the two routes ahead of a cut-off date. Withdraw the balance without swapping it and no disposal arises, and the holding period runs on. Have it converted and one does arise, at the rate of the conversion moment, which you do not set yourself. Both routes are permissible; they differ in timing and in documentation.

Where German investors can trade and hold USDC today

USDC can be traded normally at the providers licensed in the EU. Among those licensed are Kraken, Bitpanda, Coinbase and Bitvavo. Bitpanda holds a direct permission from BaFin, while other houses serve Germany via the EU passport out of Ireland, the Netherlands, Luxembourg or Malta. Which exchanges hold an EU licence and what trading there costs is in our comparison of regulated crypto exchanges. ESMA's public register and BaFin's publications are the authoritative reference works for it.

For custody the same division applies as with any other crypto-asset. Leave the token on the exchange and you carry the provider's risk and are bound to its offering; if the provider changes its offering, your own position changes with it. Keep the token in your own wallet and access hangs on the key, and you exercise the redemption right from Article 49 through a provider that still carries the token. Euros in a bank account, by contrast, are a deposit and not crypto-assets; there the deposit guarantee scheme applies, with a stablecoin it does not.

Euro stablecoins as a third option: EURC and the banks' plans

Live in Europe and count in euros and you carry a currency risk with every dollar stablecoin. A third option are euro tokens. The largest is EURC from Circle, likewise an authorised e-money token. At around $484 million in market value, though, it is markedly smaller than the two dollar variants, and less circulation usually means thinner order books and wider gaps between bid and ask. Alongside that, European banks are working on euro tokens of their own, which are not in the market so far.

For the question of this article that means: a move from USDT to USDC answers the authorisation question. The currency question stays open, and only an authorised euro token or euros in a bank account can answer it. If you use dollar stablecoins as a parking space between two purchases, you carry that risk knowingly; if you use them as a substitute for a current account, you should know the difference.

Our assessment: for a German portfolio the authorisation weighs more than the market size

From the newsroom's point of view, what speaks for USDC is that its legal framework in the EU can be documented: authorisation as an e-money token via Circle Internet Financial Europe SAS, redemption at par under Article 49, direct EBA supervision of reserve and own funds from November 12, 2026, monthly attestation reports from Deloitte. Against it speaks the concentration: a token whose reserve sits largely in a single fund and whose EU supervision converges on one authority spreads risk less broadly than a market with several authorised issuers. What speaks for USDT is market size. $183 billion against $72 billion means deeper order books and more trading pairs, above all outside Europe.

Anyone holding a balance inside the EU at licensed providers no longer has the choice in practice; cut-off dates such as October 30, 2026 and the deadline of January 8, 2027 make that decision. Trading outside that framework keeps the choice open and carries in return the risk that a token can no longer be redeemed in Europe through a licensed provider. A total loss is possible with any crypto-asset, a stablecoin included: the peg to a currency is a promise by the issuer and not a constant of nature.

Stablecoin choice: from October 30 the authorisation counts, not the size

1. First check which provider your stablecoin balance sits with and whether that provider holds an EU licence. Fees, trading pairs and the licensing status of the large houses are in the comparison of crypto exchanges.
2. Decide before your provider's cut-off date between withdrawal and swap, and factor in the tax consequence. Purchase date, rate and the new holding period can be documented with a crypto tax tool before the tax office asks for them.
3. Settle where the balance is to sit after the changeover. For self-custody you need a key that only you know; the devices for it are compared in our overview of hardware wallets.
