Fungible by Permission: One Stablecoin Across Borders Now Needs an Equivalence Finding Nobody Has Made
In one quarter the European Parliament, the US Treasury and Singapore's MAS each moved to allow one stablecoin to be issued across jurisdictions, conditioned on equivalence findings none has made. Exposed: stablecoin issuers, exchanges, banks, treasurers and payment firms.
The consensus story is convergence: GENIUS, MiCA and the UK regime are read as one rulebook under which dollar and euro stablecoins move freely. The quieter development sits in the token itself: whether a coin minted in Paris is the same coin as one minted in Boston has become a licensing question. On 7 July the European Parliament voted 390 to 86 for multi-issuance with safeguards; on 17 August the US Treasury proposed that from 18 January 2027 foreign-issued coins reach US exchanges only where the issuer will obey US lawful orders; on 1 September MAS reversed its 2023 refusal of multi-jurisdiction issuance. Each makes fungibility conditional on an equivalence finding none has made. Boards holding tokenised dollars should know which leg of the coin they own.
Signal Identification
A regulatory pivot. Multi-issuance, one brand issued by affiliated entities in several jurisdictions with reserves split between them, is how the largest compliant stablecoins already work. In one quarter three regimes moved from silence or refusal to conditional permission. The condition in every case is a supervisory judgement that the other jurisdiction's regime is comparable, and the machinery for that judgement does not yet exist anywhere.
What's Changing
The United States set the first hard date. From 18 January 2027 exchanges may not offer foreign-issued stablecoins “unless the foreign issuer has the technological capability to comply with, and will comply with, the terms of any lawful order and any reciprocal arrangement”; from 18 July 2028 only licensed issuers' coins may be sold in the US (U.S. Department of the Treasury, 17/08/2026). Freshfields calls the sequencing “a notable gap”: the restriction bites before any comparability process exists, so exchanges will list foreign coins on issuer representations; comments close 19 October (Freshfields, 25/08/2026).
The European Union opened the question it had avoided. The Commission's MiCA review, open to 30 September, states that MiCA “does not currently prohibit multi‑issuer models”, asks whether it should stay open to them, and lists “regulatory arbitrage due to fungibility of tokens” among the risks to rate (European Commission, 20/05/2026); (European Commission, 29/06/2026). It is the Commission's first such statement, and MiCA has no way to recognise a third-country regime (Skadden, 10/06/2026). Parliament then voted 390 to 86 for multi-issuance with safeguards, against the ESRB's call for a ban (Ledger Insights, 09/07/2026).
Singapore completed the set. MAS “has now reversed course” on multi-jurisdictional issuance, proposing case-by-case exemptions conditioned on a co-issuer under an equivalent regime, aggregate reserves of at least 100% of global circulation, approved rebalancing and comparable redemption terms; responses are due 16 October (Gibson Dunn, 01/09/2026). The resistance is on record too: Banque de France governor Emmanuel Moulin, citing $300 billion of stablecoins, 99% dollar-backed, wants multi-issuer models regulated more strictly (Cryptoast, 20/06/2026).
One quarter, three regimes: the decision calendar for cross-border stablecoin issuance

Disruption Pathway
Stage one runs to January 2027: three consultations close within three weeks and Treasury's lawful-order gate takes effect with no comparability process behind it, so US exchanges judge each foreign issuer's representation themselves (Freshfields, 25/08/2026). Stage two, 2027, is design: the Commission's proposal, MAS's subsidiary legislation and Treasury's Section 18 comparability rule. Stage three is 18 July 2028, when the US market closes to unlicensed and unrecognised coins (U.S. Department of the Treasury, 17/08/2026); by then equivalence findings exist or the leading coins have been split into jurisdictional versions.
Stress concentrates at three points. Reserves: split by jurisdiction, they rely on rebalancing between affiliates in stress, a risk the Commission asks respondents to rate and MAS would require under approved models (European Commission, 20/05/2026); (Gibson Dunn, 01/09/2026). Redemption: differing fees and timelines invite holders to redeem where terms are best. Lawful orders: a US freeze either reaches the EU-minted leg or it does not, and no regime yet says which. Two adaptations follow. Supervisors write equivalence as bilateral cooperation arrangements rather than statutory findings, as MAS proposes. Issuers run one reserve and redemption policy to the strictest regime, which Circle's split-reserve USDC already approximates (Ledger Insights, 09/07/2026).
Why This Matters Now
The constituency is treasurers and banks holding tokenised dollars or euros, exchanges listing foreign coins, and issuers choosing where to mint. Their contracts assume a stablecoin is one instrument; from January 2027 it is one only where a supervisor says so, and none has. Treasurers should record which issuing entity stands behind each token and on what redemption terms. Exchanges should decide what diligence on lawful-order capability they will accept, since Treasury proposes to let them rely on representations (Freshfields, 25/08/2026). Issuers should assume the strictest regime's rules bind every leg, as MAS's draft provides (Gibson Dunn, 01/09/2026). Taken together, the sources suggest the equivalence finding, not the coin rulebook, fixes cross-border stablecoin structure.
Decision-action posture for this signal: Prepare — three consultations are open and the January 2027 gate is dated, but no equivalence process exists yet, so holdings and listing policy should be set against those named triggers rather than an assumed outcome.
Counter-Argument
The strongest objection: permission on paper will not produce fungibility in practice. The Commission's questionnaire offers a straight “No, MiCA should disallow the multi‑issuance model” (European Commission, 20/05/2026); MAS expects to authorise or recognise “only a limited number” of coins (Gibson Dunn, 01/09/2026); and the US gate opens with no comparability process, which Freshfields expects to make some exchanges reluctant to list foreign coins at all (Freshfields, 25/08/2026). On that reading the outcome is ring-fencing under a shared brand.
Ring-fencing is the signal landing in its harder form. Granted or withheld, the decision has moved from the issuer's smart contract to a supervisor's equivalence judgement, and the three drafts set the same conditions: a stricter-regime reserve test, rebalancing under approval, comparable redemption terms. A coin that fails in one jurisdiction becomes two coins; one that passes becomes the template for mutual recognition. Either way, holders need to know which leg they own.
Implications
This reads as durable. Once equivalence is the instrument, stablecoin market structure follows derivatives clearing: bilateral recognitions, negotiated one pair at a time, with US comparability as the reference because the GENIUS gate binds first (Gibson Dunn, 01/09/2026). The inflection window is January 2027 to July 2028. Issuers able to run one reserve pool to the strictest regime gain; single-jurisdiction issuers and coins without a US-recognised home lose US distribution; exchanges carry the compliance risk in the interim. The Commission's consultation is the canonical statement of the choice (European Commission, 20/05/2026).
Early Indicators to Monitor
- Treasury proposing the Section 18(a) comparability process, or naming a first jurisdiction, before 18 January 2027.
- A 2027 Commission proposal keeping multi-issuance and adding an equivalence regime, as Parliament asked.
- MAS granting a first section 100A multi-jurisdictional exemption.
- A US exchange publishing a foreign-issuer diligence standard, or delisting a coin over lawful-order capability.
- A bilateral supervisory cooperation arrangement on stablecoins between MAS, an EU authority or Treasury.
Disconfirming Signals
- The Commission's 2027 proposal disallowing multi-issuance, or the ESRB's ban written into MiCA.
- Treasury adopting the strict-liability alternative, foreclosing foreign coins from US exchanges.
- Leading issuers splitting their coins into non-fungible jurisdictional tokens ahead of any equivalence finding.
- MAS finalising its regime without exercising the section 100A exemption for any arrangement.
- A redemption run on one jurisdictional leg that rebalancing fails to cover, prompting ring-fencing.
Strategic Questions
- Do we hold tokenised dollars against the issuing entity, or against the brand?
- Should our listing policy accept an issuer's lawful-order representation, or wait for a comparability finding?
- Do we mint to the strictest regime now, or run separate jurisdictional coins until equivalence lands?
- Which of our settlement flows breaks if a US freeze order reaches the EU-minted leg?
