G20 Stablecoin Regulation: Where the World Stands
A Plexo comparison framework for reading selected major stablecoin regimes by issuer access, holder rights, reserve rules, and implementation status.
By Anton Titov, Founder · Plexo Institute
A source bounded framework for comparing stablecoin regimes without turning evolving national rules into permanent labels.
A defensible comparison begins by separating enacted law, proposed policy, implementation status, and the analyst’s own framework.
What's Inside
Four moves for reading the G20 stablecoin regulatory map.
This is not an exhaustive legal map of the G20. It is Plexo’s comparison method, illustrated with selected primary sources. For any real corridor, confirm the current position with the relevant regulator and the particular product, issuer, customer type, and service.
Plexo compares a regime through four lenses: who may issue, what holder and redemption rights exist, which assets and controls support the token, and whether the relevant rule is enacted, proposed, or operational. These lenses are analytical tools; no country is assigned a permanent legal label by this page.
The EU MiCA Regulation is in force with category-specific rules. The US GENIUS Act is enacted, but its statutory effective date depends on its final implementation conditions. A comparison that treats both as equally complete operational regimes would be misleading.
The Bank of England’s 2025 paper proposes a regime for sterling-denominated systemic stablecoins; it is not a statement that every UK stablecoin activity already follows those proposed limits. Country-by-country comparisons should identify the regulator document and its legal status before drawing an operator conclusion.
The Regulatory Landscape
Across the G20 and adjacent major financial centers, stablecoin policy has moved from absence to enacted legislation, formal regulation, or substantive draft frameworks. The regimes disagree on almost every dimension: who can issue, who can hold, whether yield is permitted, and how transit is treated versus holding. The result is four distinct regime archetypes that operators must navigate corridor by corridor.
The page is a methodology with selected primary sources, not a complete legal inventory.
Issuer path, holder rights, reserve and redemption rules, and implementation status.
The Four Archetypes
The lenses keep legal status separate from policy interpretation.
No general page can safely place every G20 jurisdiction into a permanent bucket. Instead, Plexo uses four lenses for a named token and route: issuer path, holder and redemption rights, reserve and control rules, and the status of the applicable legal instrument.
Holding And Yield Decide The Regime Type
The same sovereignty question sorts markets into permissive, contained, transit-only, or restrictive paths.
Two policy controls
Can retail users hold balances? Can the instrument pay yield?
Permissive
Reserve-currency zones tolerate retail balances under issuer rules.
Contained
Non-reserve currencies allow payment utility while defending deposits.
Transit-only
Stablecoins exist during payment, then leave the user balance sheet.
Restrictive
Political or monetary controls push activity offshore.
A policy objective such as monetary sovereignty can inform an analyst’s hypothesis, but it does not prove a regulator’s purpose or a country’s future policy.
For each route, record the official source, the document date, whether it is law or proposal, the issuer category, the customer type, the asset, and any transition or exemption. Only then compare constraints across corridors.
The Permissive Regimes
The US and EU illustrate different legal architectures and different implementation status.
MiCA and GENIUS should not be collapsed into a single “permissive” model. MiCA has category-specific rules for EMTs, ARTs and CASPs. GENIUS defines permitted issuers and reserve standards, but its effective date follows the statute’s implementation condition. Neither fact alone answers whether a particular customer, issuer, token or service is permitted on a named route.
| Jurisdiction | Official instrument | Status for this comparison | What to verify |
|---|---|---|---|
US | GENIUS Act | Enacted; effective date and rulemaking status must be checked | Permitted issuer category, eligible reserve assets, effective date, final rules, issuer approval |
EU | MiCA + TFR | In force; category and transition rules apply | Whether the token is EMT or ART, issuer status, CASP service and applicable TFR duties |
UK | Bank of England systemic-stablecoin consultation | Proposed policy, not a final universal UK rule | Whether the use case is systemic, recognition status and the final regime |
The GENIUS Act establishes a federal framework for payment stablecoins and reinforces the policy goal of extending US dollar infrastructure globally.
Key provisions include federal and state issuer pathways, reserve segregation, monthly attestations, 100% reserves in cash or short-duration Treasuries, prohibition on interest or return on payment stablecoin balances, broad retail access subject to issuer and intermediary licensing, and explicit support for foreign-held dollar stablecoins as an extension of dollar infrastructure.
For operators, GENIUS is the clearest legal basis for USD stablecoin clearing infrastructure. The federal pathway reduces the state-by-state patchwork, while the no-yield prohibition keeps payment stablecoins from directly competing with deposits.
The Contained Holding Regimes
Contained regimes allow the infrastructure while trying to prevent stablecoins from becoming savings substitutes.
The United Kingdom example illustrates why labels must be bounded: the Bank of England paper sets out a proposed regime only for sterling-denominated systemic stablecoins, while other UK use cases would sit in different regulatory paths. A jurisdictional comparison should not generalise that proposal to other countries or all customer types.
| Example | Official source status | How to use it safely |
|---|---|---|
UK systemic sterling stablecoins | Bank of England consultation, published November 2025 | Treat £20,000 individual and £10m business limits as proposals for systemic cases, not as a final universal UK rule |
EU MiCA | Enacted EU regulation | Check the token category, issuer path and relevant transition or service provision |
US GENIUS Act | Enacted federal statute with implementation timeline | Check effective date, final rules, permitted issuer status and foreign-issuer conditions |
The Bank of England proposes individual and business holding limits for certain systemic sterling stablecoins. Those numbers and their underlying assumptions are consultation material, not a current global template.
For operators, the practical lesson is simple: identify the exact regulated use case and document status before reusing a control from another jurisdiction.
Do Not Infer a “Transit-Only” Regime
A product flow may be designed for rapid conversion without that design becoming a country’s legal category.
“Transit-only” can describe an operator design: fiat is converted for a settlement step and reconverted at the destination. It is not a reliable substitute for checking whether local law permits issuance, custody, exchange, holding, marketing, or cross-border service for the named product and customer.
A fast-conversion design may reduce duration risk in a particular flow, but it does not remove issuer, custody, sanctions, consumer-protection, FX, or Travel Rule obligations.
Before calling any corridor “transit-only”, identify the official rule for each leg and verify whether the relevant customer is permitted to acquire, hold, transfer, redeem, or receive the token.
Do Not Infer a “Restrictive” Regime
A regulator’s legal perimeter should not be translated into an unproven account of political intent.
A jurisdiction can limit one stablecoin activity while allowing another, change its perimeter over time, or apply different rules to mainland, offshore, institutional, consumer, issuance, exchange, or custody activity. The only defensible account is the dated rule and its specified scope.
Do not use a global comparison page as evidence for a current China, Hong Kong, India, Nigeria, Brazil, Japan, UAE, Singapore, or other country conclusion. That conclusion needs the current local primary rule and its scope.
This page deliberately does not infer intent, predict policy direction, or treat offshore arrangements as proof of a domestic legal status.
A historical change can be useful context only when the primary source, date, legal change, and scope are shown. It does not justify a forecast that another country will follow the same path.
Where the Frameworks Are Converging
Global policy recommendations are not a substitute for national law.
The FSB recommendations provide a global policy reference for effective regulation, supervision and oversight of global stablecoin arrangements. They do not establish that each G20 jurisdiction has enacted the same requirements or that a proposed rule is in force.
For a named regime, check issuer authorisation, redemption claim, reserve eligibility and custody, disclosure, operational resilience, AML/sanctions obligations, and wind-down or insolvency treatment.
Then record whether each item comes from enacted law, final rule, proposal, supervisory guidance, or an issuer’s own representation.
For each origin and destination, test the issuer, token, customer category, service, marketing activity, redemption access, data-transfer obligations, local licensing, and foreign-issuer pathway. Do not assume that authorisation in one jurisdiction creates automatic status in another.
Counter-Arguments & Limitations
The archetype map is useful, but regulation is moving faster than the categories can fully capture.
This framework map is a snapshot. Regulation is moving faster than publication cycles, and by the time a reader reaches the article at least one jurisdiction may have shifted. The archetype classification simplifies regimes that contain internal contradictions.
The argument: Singapore started as transit-only, expanded to contained holding through SCS in 2023, and now keeps some yield treatment inside institutional controls. The UK proposed regime contains elements of both contained and permissive design. Classification into four buckets loses these nuances.
The answer: the archetypes describe regulatory intent, not implementation detail. Singapore shows that jurisdictions move between archetypes as they gather evidence, and that movement is itself the pattern the article maps. The archetypes are most useful as a snapshot of current design intent, not as permanent categories.
The argument: the US GENIUS Act allows T-bills as reserves; MiCA requires specific liquidity composition; and the UAE permits a different reserve composition under its rulebook. A shared headline standard can mask significant differences in reserve quality, custody, audit cadence, and enforcement capacity.
The answer: this limitation is valid and important. Reserve composition and enforcement are the second-order questions that matter most for operators. Two jurisdictions can both require 100% reserves and still produce fundamentally different risk profiles. Operators must look beyond the headline to reserve composition, audit frequency, and insolvency treatment.
