Two documents will decide, in January, which dollar tokens a corporate treasury may keep holding through its providers. The first is a European supervisory opinion addressed to national regulators. The second is a United States statute whose effective date arrives ten days later, with a Treasury rulebook still open for comment. Neither mentions a corporate treasury. Neither names a token. Both sort the token by its issuer.

Key Takeaways

  • 8 October 2026: the European Securities and Markets Authority (ESMA) published Opinion ESMA75-113276571-1742. It asks national authorities to require remediation of legacy exposures to stablecoins that do not comply with the Markets in Crypto-Assets Regulation (MiCA) "no later than three (3) months following the date of publication". We compute that outer limit as 8 January 2027.
  • GENIUS Act effective date: the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act takes effect on the earlier of 18 months after enactment, which is 18 January 2027, or 120 days after the primary federal regulators issue final rules (Section 20). Treasury's August 2026 proposal states that it expects the effective date to be January 18, 2027.
  • 18 July 2028: from that date a digital asset service provider may not offer or sell a payment stablecoin to a person in the United States unless it is issued by a permitted issuer or a qualifying foreign issuer (Section 3(b)(1); proposed §1523.3(a)). Comments on Treasury's proposal close 19 October 2026.
  • Who is bound: both regimes bind the provider or the issuer, not the holder. ESMA's opinion now lists custody and transfer among the services in scope; its January 2025 statement had said that "mere custody and transfer of these crypto-assets should remain possible".
  • Dollar stablecoins total about USD 311 billion as of 12 October 2026. The same balance can be eligible in one subsidiary and in run-off in another on the same day, so a group policy needs an eligible-issuer test written per regime and per entity.

Two Clocks, Ten Days Apart

The sorting key matters more than the dates. A treasury policy that admits "USD stablecoins" as one instrument class will give the wrong answer in January, because the question each regulator asks is not what the token is. It is who issued it, under which authorisation, and whether the provider in front of the treasury may keep serving it.

The two January dates are different kinds of date. The European one is a supervisory outer limit that national authorities apply to the firms they supervise. The American one is a statutory effective date. What they share is the sorting key: the issuer's status under each regime.

Clock One: The EU Service Provider Wind-Down

On 8 October 2026 ESMA published an opinion on "the provision of crypto asset services in relation to non-MiCA-compliant asset-referenced tokens and e-money tokens". Its legal basis is Article 29(1)(a) of the ESMA Regulation, under which ESMA provides opinions to national competent authorities "for the purpose of building a common Union supervisory culture and consistent supervisory practices". The addressee is the supervisor, not the firm and not the client.

The opinion builds on two earlier texts. European Commission Q&A 2404 and ESMA's public statement of 17 January 2025 set out when certain crypto-asset services amount to an offer to the public or an admission to trading under Articles 16(1) and 48(1) of MiCA, Regulation (EU) 2023/1114. Titles III and IV of MiCA, which govern ARTs and EMTs, became applicable on 30 June 2024. The October opinion states that it "does not change the position expressed above". It goes further on a different question: whether a MiCA-authorised provider may keep serving a non-compliant token at all.

The answer in paragraph 12 is short. "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." The reasoning in paragraph 13 is the part a treasurer should read twice. The risk, ESMA says, does not arise from the service. It is "inherent to the non-compliant status of the ART or EMT due to the absence of the issuer-level safeguards required by MiCA". Paragraph 17 lists those safeguards: "redemption rights, reserve-of-assets or safeguarding requirements, governance obligations, disclosure requirements and ongoing supervisory oversight". That list is a credit checklist, not a technology one. ESMA ties it to the provider's duty under Article 66(1) of MiCA to act "honestly, fairly and professionally in the best interests of clients".

Three operational points follow.

First, the scope is every service. Paragraph 21 asks supervisors to consider whether a provider's services "individually or in combination" allow EU clients to "acquire, trade, exchange, subscribe for, increase their exposure to, or otherwise access or maintain" such tokens. It names all of them: operating a trading platform, exchange, execution, reception and transmission of orders, placing, advice, transfer services, custody and portfolio management. Paragraph 22 asks for "technical, contractual and organisational controls" that prevent EU clients "from acquiring or increasing positions". This is a change of emphasis from January 2025, when ESMA's statement said that "mere custody and transfer of these crypto-assets should remain possible". A treasury that holds a non-compliant token through an EU custodian and does nothing else is now inside the perimeter.

Second, disclosures are not a cure. Paragraph 19 says that "reliance on warnings, disclosures or client acknowledgements would not sufficiently address the concerns identified in this Opinion", because warnings "do not prevent the continued availability and use" of the token, and because the MiCA protections "operate collectively". A signed risk acknowledgement from the treasury does not keep the balance in place.

Third, the exit is defined and dated. Paragraphs 23 and 24 allow supervisors to permit "strictly limited residual services" where they are "necessary to ensure an orderly wind-down and to avoid client detriment", limited to "the liquidation, conversion, withdrawal, transfer or safekeeping of existing holdings". Those residual services should be "time-limited, clearly communicated to clients and subject to close supervisory scrutiny". Paragraph 27 sets the clock. Where supervisors identify remaining legacy exposures, "they should require remediation as soon as possible and no later than three (3) months following the date of publication of this Opinion", with any continuation "strictly limited to sell-only, conversion, transfer or withdrawal functionalities". Three months from 8 October 2026 is 8 January 2027. That date is our computation. The opinion gives the period, not the day.

One more fact about the document. It names no token and no issuer. Press coverage has attached names to it; the opinion does not. Whether any particular token is non-MiCA-compliant turns on the issuer's authorisation status and on the supervisor's assessment, and a treasury should take that answer from its provider in writing, not from a headline.

Clock Two: The US Issuer Test

The GENIUS Act became Public Law 119-27 on 18 July 2025. Section 20 sets the effective date as "the earlier of (1) the date that is 18 months after the date of enactment of this Act; or (2) the date that is 120 days after the date on which the primary Federal payment stablecoin regulators issue any final regulations implementing this Act". Eighteen months after enactment is 18 January 2027. Treasury's August 2026 proposal says, in a footnote, that it expects the effective date to be January 18, 2027 (in its words, "expected to be January 18, 2027"). We note one arithmetic consequence: 120 days after any final rule issued after 20 September 2026 falls later than 18 January 2027, so the 18-month limb now governs unless a primary federal regulator issued a final rule on or before that date. We find no such rule in the Federal Register as of 12 October 2026.

The Act contains two provider-side prohibitions, and they switch on at different times. Section 3(b)(2) applies from the effective date. It makes it unlawful for "any digital asset service provider to offer, sell, or otherwise make available in the United States a payment stablecoin issued by a foreign payment stablecoin issuer unless the foreign payment stablecoin issuer has the technological capability to comply, and will comply, with the terms of any lawful order and any reciprocal arrangement pursuant to section 18". Treasury's proposal would let a provider rely on the issuer's representation to that effect, but only after "reasonable due diligence" and not where the provider "knows, has reason to know, or should know that the representation is false".

Section 3(b)(1) applies "beginning on the date that is 3 years after the date of enactment", which Treasury writes out as July 18, 2028. From that date it is unlawful "for a digital asset service provider to offer or sell a payment stablecoin to a person in the United States, unless the payment stablecoin is issued by a permitted payment stablecoin issuer". Proposed §1523.3(a) codifies this and spells out the foreign-issuer exemption the statute cross-references: a token "issued by a foreign payment stablecoin issuer that meets the criteria set out in section 18(a) of the Act".

Section 18(a) is the foreign path. The Section 3 prohibitions do not apply to a foreign issuer only if all four conditions hold: its home regime is one the Treasury Secretary "determines, pursuant to subsection (b), is comparable to the regulatory and supervisory regime established under this Act"; the issuer "is registered with the Comptroller" of the Currency; it "holds reserves in a United States financial institution sufficient to meet liquidity demands of United States customers" unless a reciprocal arrangement provides otherwise; and its home country is not under comprehensive US sanctions or designated a jurisdiction of primary money laundering concern. The Section 3 proposal implements the prohibitions. The comparability determination is a separate Treasury act under Section 18(b).

Section 3(c)(1) lets Treasury create safe harbours that are "consistent with the purposes of the Act", "limited in scope" and "apply to a de minimis volume of transactions". The proposal asks whether any should be time-based or size-based and floats, as an example only, a threshold "such as $1 million dollars per year". Nothing is decided. Comments on the proposal, published at 91 FR 53368 on 18 August 2026 under docket TREAS-DO-2026-0496, "must be received on or before October 19, 2026".

The issuer side has its own rulebook, and it is also unfinished. The Federal Deposit Insurance Corporation (FDIC) proposed an approval process for bank subsidiaries on 19 December 2025, the Office of the Comptroller of the Currency (OCC) published its proposal on 2 March 2026, the FDIC its standards on 10 April 2026. On 24 September 2026 the Federal Reserve requested comment on two proposals covering reserves, capital, risk management and "rules for Board-supervised firms that safekeep the assets backing payment stablecoins". The Federal Reserve notices appeared in the Federal Register on 29 September 2026 with comments due 30 November 2026. As of 12 October 2026, each remains a proposal.

Why the Holder Is Not the Addressee

Read the two texts for the word "holder" and the pattern is plain. The ESMA opinion is addressed to supervisors and directs its expectations at CASPs. Section 3 of the GENIUS Act is addressed to issuers in subsection (a) and to digital asset service providers in subsection (b). Neither document, in the passages we have quoted, places an obligation on the person who holds the token.

For a corporate treasury the consequence is procedural, and it is the whole point. The treasury will not receive a letter from ESMA or from the US Treasury. It will receive a notice from its custodian, its exchange or its payment provider, saying that a balance has moved to sell-only, that conversion is available until a date, or that transfers out must be completed by a cut-over. Paragraph 24 of the opinion expects exactly that: residual services should be "clearly communicated to clients". The treasury's first sight of January will be a provider's email.

Now place one balance in two entities. A European subsidiary holds a dollar token through an EU-authorised provider. The question that decides eligibility is whether the token's issuer holds a MiCA authorisation under Title III or Title IV. A US affiliate holds the same token through a US provider. From 18 January 2027 the question is whether the issuer is a foreign issuer able and willing to comply with lawful orders, and from 18 July 2028 whether it is a permitted payment stablecoin issuer or a Section 18(a) foreign issuer. These are different tests with different answers. The documents provide no automatic cross-recognition: the US route for a foreign issuer runs through a Treasury comparability determination and OCC registration, and the EU route runs through MiCA authorisation of the issuer. The same balance can be eligible in one subsidiary and in run-off in another on the same day.

That is why "USD stablecoin" cannot be an instrument class in a group policy. The instrument is the issuer, in the regime of the entity that holds it.

Three Clauses Before January

A policy does not need a new chapter. It needs three clauses, written so that a provider's notice can be handled by procedure rather than by meeting.

1. An eligible-issuer test, per regime and per entity

The clause names the regime that governs each holding entity and the test that regime applies to the issuer. For an EU entity, the test is MiCA authorisation of the issuer under Title III or Title IV, confirmed by the provider in writing. For a US-facing entity, the test is the issuer's status under the GENIUS Act as the Act takes effect: from 18 January 2027, a foreign issuer's documented capability to comply with lawful orders and reciprocal arrangements; from 18 July 2028, permitted-issuer status or a Section 18(a) determination. The clause should require the evidence, not the assertion.

Illustrative clause, not a template: "Entity [X] may hold a dollar-denominated token only where the issuer holds [a MiCA Title III or Title IV authorisation / permitted payment stablecoin issuer status or a Section 18(a) determination], evidenced by the provider in writing and reviewed at each quarter end."

2. A provider wind-down protocol

The clause states what the treasury does on the day a provider restricts a balance to sell-only, conversion, transfer or withdrawal. It names the conversion path (into which instrument, at which provider), the receiving bank account by entity, the cut-over timeline the treasury will accept, and who signs the instruction. It also states what the treasury will not do: increase the position, move it to an entity where it is ineligible, or treat a provider's risk acknowledgement as a substitute for exit.

Illustrative clause, not a template: "On receipt of a provider notice restricting any token balance, Treasury Operations will convert or transfer the balance to [named account] within [N] business days, under the signature of [role], and will not increase or relocate the position in the interim."

3. The calendar

The clause fixes the dates the policy is tested against and assigns an owner to each. The near dates are 19 October 2026 (Treasury comment close), 8 January 2027 (ESMA outer limit, our computation), 18 January 2027 (GENIUS effective date at the latest) and 18 July 2028 (the Section 3(b)(1) offer-and-sale prohibition). The clause should require a provider inventory, per entity, to be refreshed before each date.

Illustrative clause, not a template: "The eligible-issuer register and the provider inventory for each entity will be reviewed by [owner] no later than ten business days before each date in Schedule [Y], and the review will be minuted."

Latin American Groups: One Balance, Two Boxes

Latin American corporates have a particular exposure to the sorting problem, because they tend to hold dollar tokens through a mix of providers. An exporter's treasury may keep a working balance with a regional exchange, a settlement balance with a US payment provider, and a custody arrangement with a European bank for a subsidiary in Madrid or Lisbon. Each provider sits under a different regime. Each will send its own notice, on its own date, about the same token.

Consider two archetypes. The first is an exporter with no foreign subsidiary that receives dollar tokens from buyers and converts them locally. Its providers may be domestic, but the token's issuer is not, and the exporter's US-facing provider will apply the GENIUS test from 18 January 2027 regardless of where the exporter sits. The second is a group with a European subsidiary that holds the same token for intercompany settlement through an EU-authorised custodian. For that subsidiary the ESMA opinion is the operative text, and the custodian's remediation notice may arrive before 8 January 2027.

In both cases the group policy fails if it is written at group level. The eligible-issuer test has to be written per entity, because the regime follows the entity, not the group. The provider inventory has to be kept per entity for the same reason. And the wind-down protocol has to name a receiving account in the entity's own jurisdiction, because a conversion path that runs through another entity may move the balance from a box where it is eligible to a box where it is not.

Latin American treasuries have handled this shape before, with correspondent banking and with sanctions screening. The discipline is the same: know which rulebook each account sits under, and keep the evidence where the auditor can find it.

The Question Underneath

The dollar stablecoin market stands at about USD 311 billion as of 12 October 2026, and the holders of that float are not the addressees of either January text. Their providers are. The International Monetary Fund's October 2026 Global Financial Stability Report makes the policy direction explicit: tokenised securities should be settled "in safe and widely accepted forms of money", and it lists stablecoins among the private settlement alternatives "with systemic risk implications". Regulators on both sides of the Atlantic are now acting on the issuer, which is where that risk lives. We set out what the main systems chose as their settlement money in Whose Money Settles.

For a treasurer the question underneath is not whether to hold dollar tokens. It is whether the policy can state, for each entity, who issued the token, under which authorisation, and what the treasury does on the day the provider says the balance must go. If those three answers are not already in the policy, January will supply them in a provider's email, on the provider's timeline.

For the Treasurer: Before January, write one line per holding entity that names the issuer's status under that entity's regime and the account the balance converts into. If the line cannot be completed from documents the provider has already given you, the balance is in the wrong box, however well it settles.
