US rule on stablecoin interest takes effect January 18, 2027: what changes for investors in Europe

Here is what is documented: the US banking regulator Office of the Comptroller of the Currency, or OCC, presented its final rule on payment stablecoins on October 21, 2026. The rule takes effect on January 18, 2027, the same day the underlying statute begins to bite. The ban on paying holders interest or a yield purely for holding a stablecoin remains in place. What the agency has struck out is a passage from the draft under which certain payments routed through third parties would have counted from the outset as circumventing that ban. Our own assessment follows further down: the case-by-case review that replaces that presumption moves the question of which reward model is permitted out of the rule text and into supervisory practice.

The short answer to what this changes in Germany is: nothing for now. Anyone holding USDC or USDT here has long lived under a stricter regime. Article 50 of the EU regulation on markets in crypto-assets, or MiCAR, prohibits issuers of e-money tokens from granting interest. The American rule is interesting all the same, because it answers whether the interest gap stays open anywhere in the world. That answer is more nuanced than the bare headline "ban on interest stays" suggests.

What the OCC decided on October 21, 2026

The agency published its bulletin numbered 2026-50, pulling together in it the final version of every provision the stablecoin statute obliges it to issue. In its own wording, the rule enters into force on January 18, 2027. The OCC has bundled the largest part of the new duties into a newly created section of its rulebook, carried as Title 12, Part 15 of the Code of Federal Regulations. Alongside that it amends existing provisions on capital adequacy, on early supervisory intervention, on fees and on procedural law.

A payment stablecoin is, in this scheme, a token redeemable for a fixed amount in state currency and expressly intended as a means of payment. That intended purpose explains why both legal orders take such a hard line on interest: a means of payment is meant to circulate, an investment is meant to sit still.

The agency followed up the same day with a second bulletin covering revised reporting forms for licensed issuers. When it will actually start accepting applications and exemption requests it has left open, saying it will announce that separately. No approved issuer therefore exists in the United States as of today.

The interest ban in the GENIUS Act: what issuers of payment stablecoins may not do

The statute itself bars issuers from paying their holders interest or a yield where that payment is made solely because someone holds, uses or retains the token. At the same time it obliges the OCC and the other banking supervisors to prevent circumvention of that ban. This is the point at which the agency's concrete design decides the practical effect.

The rationale for the ban is not crypto-specific. The thinking comes from banking law and is called deposit flight. If a stablecoin issuer pays interest on the balances it has issued, it competes with the current account and the overnight deposit without being fully subject to deposit insurance and banking supervision. The wider the interest gap, the more money migrates out of the banking system, and the less credit a bank can extend. The same consideration sits behind Article 50 of MiCAR.

The deleted presumption for reward arrangements with third parties

The spring draft went further than the version now adopted. It contained a presumption: certain arrangements between an issuer and a third party on paying a yield were to count as a breach of the interest ban without the supervisor having to prove it in the individual case. What was meant were structures in which the issuer does not pay itself, but an affiliated company, a trading platform or a distribution partner with which a contractual or economic relationship exists.

That presumption no longer appears in the final rule. Instead the OCC intends to review such arrangements one by one. The Bank Policy Institute, the association of the large American banks, criticised this on the day of publication and writes in its statement of October 21, 2026 that without a clear presumption and without a transparent procedure it is hard to tell which practices cross the line.

No blanket grandfathering: the OCC reviews reward models individually

From the deletion follows something that looks at first glance like relief and on closer inspection is an uncertainty. An existing reward programme is neither expressly prohibited nor expressly tolerated by the new rule. It gets no blanket grandfathering, but lands in the case-by-case review. Anyone running such a programme learns where they stand only through supervisory practice, and the agency has so far declined to publish the results of those reviews under any fixed procedure.

For holders in Germany this is an observation rather than an exposure. Users here receive no interest on e-money tokens on regulated European platforms in any case. For which tokens are licensed under MiCAR here at all and where they trade, the current overview is in the stablecoin comparison.

12 CFR 15: reserve assets, redemption, custody and supervision in one section

According to the agency, the new section governs an issuer's permitted activities, the reserve assets, redemption, risk management, examinations and ongoing supervision, custody, the licensing procedure, the review of foreign issuers, the withdrawal of a licence, and a capital and operating reserve as a backstop. The details of these duties sit in the regulatory text and not in the bulletin, which only names the subjects.

The order of the topics gives away what the legislator was after. Reserve and redemption come first, because a payment stablecoin is only a means of payment if it can be returned at face value at any time. Custody and licence withdrawal stand beside them, because the supervisor needs a lever when that ceases to hold. The details are in the OCC's bulletin 2026-50.

Foreign issuers: when the OCC also supervises issuers from abroad

One point of the new rule concerns Europe directly. The OCC records in its bulletin that it gains supervisory powers over foreign issuers of payment stablecoins. The scope covers, besides national banks, federal savings associations and their subsidiaries, also federally licensed branches, non-banks that are seeking or have obtained a licence as a federally approved issuer, and state-licensed issuers insofar as the OCC holds regulatory or enforcement powers over them.

A European issuer wanting to bring a euro stablecoin into the American market will therefore operate within two supervisory systems at once. Which duties the European side carries we have written up in our overview of the MiCA licensing obligations for crypto companies.

Money laundering and sanctions are missing: what the Treasury still has to settle

The final rule deliberately leaves out a large area. Provisions on the Bank Secrecy Act, on anti-money-laundering and on the sanctions lists of the Office of Foreign Assets Control are not included. For those the OCC announces a separate rulemaking in coordination with the Treasury. It names no date.

This is more than a formality. With stablecoins in particular, anti-money-laundering supervision decides which addresses can be frozen and under what conditions an issuer blocks tokens. As long as that part is missing, the American framework is finished in its market rules but not in its control architecture. The background to this legislative process and the state of play before the final version we described in our article on the GENIUS Act rules through 2027.

Our own research: the final version is not yet in the Federal Register

The binding full text of an American regulation appears in the Federal Register, the official gazette of the United States. The final stablecoin rule had not been published there as of October 22, 2026. All 14 OCC entries under the keyword payment stablecoin were checked; the most recent relevant entry is the proposed rule of March 2, 2026. cryptoticker.io carried out this research itself on October 22, 2026.

In practical terms that means what is publicly available right now is the agency's bulletin and the accompanying notices. The statutory text that lawyers and issuers will work from comes later. Anyone who needs a statement on an individual reward model is better off waiting for that text.

Article 50 MiCAR: in the EU, interest on e-money tokens has long been prohibited

The European rule is older and shorter. Article 50 of MiCAR prohibits issuers of e-money tokens from granting interest, by way of derogation from Article 12 of the E-Money Directive, which had regulated the question more openly before. The ban does not stop at the issuer: it equally captures crypto-asset service providers working with such tokens, even where they do not issue the token themselves and merely custody or trade it.

The European concept of interest is broadly drawn. It captures any remuneration tied to the holding period, regardless of what it is called and who pays it. That is precisely why cashback and reward models on stablecoin balances have largely disappeared in the EU while they carried on elsewhere. The rules for stablecoins under MiCAR have applied since June 30, 2024.

USDC and USDT in Germany: holders face no action today

Concretely: nothing that forces a step today. The American rule addresses issuers and the supervisor, not holders. Neither a token's redeemability nor its treatment on a European platform changes because of it. Two things are worth a look all the same.

The first is the venue. A provider licensed in Germany is fully subject to MiCAR; a non-European provider is not. Anyone using a reward programme on a platform outside the EU is relying on a practice that, in the United States from January 2027, sits under case-by-case supervisory review. The second is tax. If a remuneration from such a programme accrues to you, that inflow has to be assessed for tax, and the classification turns on the individual case. A reliable statement on that comes from a tax adviser, not from an editorial desk.

Our assessment: case-by-case review creates room, but not clarity

From the editorial desk's point of view, the deletion of the presumption is the real event of the day, not the surviving interest ban. In favour of that reading: the ban already stood in the statutory text and the agency could not have loosened it at all, whereas the presumption was a supervisory decision that it has now revised. Against it: nobody can quantify the practical effect of that change today, because the statutory text is not yet published and the OCC has named no procedure for its individual decisions.

Paige Pidano Paridon, Executive Vice President and co-head of Regulatory Affairs at the Bank Policy Institute, put it this way in the statement linked above: "The decision to omit the interest presumption replaces clarity with ambiguity and exposes the banking system and its customers to the risk of deposit flight." That is the position of a banking association and therefore the position of an interested party. What is documented at this point is the fact of the deletion, not its consequence.

What can be inferred from it for the EU is limited. Article 50 of MiCAR knows no presumption that could be struck out, because it prohibits interest directly and includes service providers. A European loosening would be decided by the legislator, not by a supervisory authority. There are currently no signs of one.

Stablecoin interest: nothing changes in the EU before January 18, 2027

Three points count now:

1. Place your venue. Check whether your provider holds a MiCAR licence in the EU or operates outside it, because that determines which rulebook applies to your balance. Which houses are licensed is set out in the comparison of regulated crypto exchanges.
2. Name the source of the yield. Interest on e-money tokens is prohibited in the EU; earnings from other sources are not. If you are looking for a yield, look at what the return actually rests on, for instance with the staking rewards platforms.
3. Document the inflows. Record every remuneration from a reward programme with its date and equivalent value, as long as the tax classification turns on the individual case. The tax software and portfolio trackers help with that.
