A G20 stablecoin regulation map across four regime archetypes: permissive, contained, transit only, and restrictive.

Reader Brief

The world's largest economies have now moved from stablecoin-policy absence to stablecoin-policy fragmentation. The US enables broad retail holding. The EU prescribes reserve standards. Singapore separates transit from holding. China bans. This is a map of where each framework lands.

What's Inside

Four moves for reading the G20 stablecoin regulatory map.

The perspective starts with the regulatory shape of stablecoins, not with individual country summaries. Each jurisdiction answers the same sovereignty question through a different combination of holding permission, yield treatment, licensing, reserve rules, and cross-border recognition.

The four archetypes: every G20 framework answers one sovereignty question.

Permissive regimes, including the US and EU, extend currency dominance through stablecoins. Contained regimes, including the UAE, UK, and Singapore, allow infrastructure benefits with holding caps and zero yield. Transit-only regimes, including Chile and Singapore before SCS, keep stablecoins in the payment window rather than on balance sheets. Restrictive regimes, with China as the clearest example, block domestic stablecoin use while engaging selectively offshore.

Permissive regimes: GENIUS Act and MiCA as competing dollar and euro extension strategies.

The US and EU both permit broad retail holding with 100% reserve requirements. GENIUS is framed around OCC-chartered issuers, T-bill reserves, and no yield. MiCA provides unified 27-state authorization, Transfer of Funds Regulation obligations, and a systemic issuer regime. Both bet that enabling stablecoins costs less sovereignty than losing flows to unregulated alternatives.

Contained and transit-only regimes: the pragmatic middle path for non-reserve currencies.

The UK proposal uses GBP20K individual caps and zero yield, with BoE modeling a maximum 2-3% deposit outflow. The UAE splits retail AED-only treatment from institutional multi-currency activity. Singapore evolved from transit-only treatment toward contained holding through the SCS framework.

Convergence and divergence: four baselines shared, three gaps that matter.

Major frameworks converge on issuer licensing, 100% reserves, Travel Rule compliance, and no yield on payment stablecoins. They diverge on holding caps, yield on non-payment stablecoins, and cross-border mutual recognition. No major framework treats foreign-issued stablecoins as automatically domestically equivalent.

The Regulatory Landscape

Stablecoin regulation has moved from absence to fragmentation: the largest economies have frameworks, but not one shared model.

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 [1].

4 Distinct regime archetypes. Permissive, contained, transit-only, and restrictive.

The Four Archetypes

The archetypes are defined by retail holding permission and yield treatment.

Every G20 stablecoin framework falls into one of four archetypes. The archetypes are defined by how the jurisdiction treats two core questions: can retail users hold stablecoin balances, and can stablecoins bear yield? The combinations produce distinct regime patterns.

Stablecoin regulation archetype matrix organized by retail holding permission and yield permission, with permissive, contained, transit-only, and restrictive outcomes. — The core sovereignty controls are holding and yield: they decide whether stablecoins become money-like balances, payment tools, or offshore activity.

Each archetype answers one sovereignty question: how much stablecoin holding can a jurisdiction tolerate?

The sovereignty spectrum maps directly to monetary position. - **Permissive** (US, EU, Japan): reserve currency issuers or large monetary zones. USD stablecoins extend dollar hegemony, while the EU enables EUR stablecoins defensively, preventing all-dollar settlement in European corridors. - **Contained** (UAE, UK, Singapore, Brazil): non-reserve currencies with developed financial sectors. The UK proposal uses a GBP20K retail cap plus zero yield, and the UAE splits CBUAE retail AED-only treatment from ADGM institutional multi-currency treatment. - **Transit-only** (Singapore pre-SCS, Chile): full sovereignty preservation with payment modernization. Stablecoin exposure is measured in seconds rather than balance-sheet duration. - **Restrictive** (China, pre-2023 Nigeria/India): capital controls or political priority. Nigeria illustrates how restriction can help create the informal market it seeks to prevent.

The Permissive Regimes

The US and EU permit broad retail holding while turning reserve and issuer rules into the control layer.

The US GENIUS Act and EU MiCA, covering the world's two largest currency zones, both permit broad retail holding with 100% reserve requirements. The policy bet is that extending dollar or euro infrastructure globally through stablecoins costs less sovereignty than losing payment flows to unregulated alternatives.

Jurisdiction	Framework	Effective	Key features
US	GENIUS Act	2025	Federal framework; OCC-regulated issuers; no yield on payment stablecoins; broad retail access [2]
EU	MiCA + TFR	2024	Issuer licensing; reserve standards; retail redemption rights; Travel Rule at EUR1,000 [3]
Japan	Payment Services Act amendments	2023	Bank/trust issuance only; strict reserve; limited retail access [1]

US GENIUS Act: OCC-chartered issuers, 100% T-bill reserves, and no yield [2].

The GENIUS Act establishes a federal framework for payment stablecoins and reinforces the policy goal of extending US dollar infrastructure globally [2]. 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.

EU MiCA: ARTs and EMTs under unified authorization across 27 member states [3].

MiCA provides one of the most comprehensive stablecoin frameworks globally [3]. Key provisions include specific authorization for Asset-Referenced Tokens and E-Money Tokens; fully segregated, liquid reserves with composition requirements; redemption at par within reasonable time; disclosure requirements; additional rules for significant issuers; and Travel Rule integration through the Transfer of Funds Regulation. For operators, MiCA's passport matters because a single authorization can cover 27 member states. European Travel Rule implementation also creates a heavier compliance-data footprint than some other major regimes.

The Contained Holding Regimes

Contained regimes allow the infrastructure while trying to prevent stablecoins from becoming savings substitutes.

The UAE, UK, Singapore, and Brazil all permit stablecoin activity with explicit guardrails: holding caps, no yield, and custodial or licensed access. This is the common archetype among non-reserve-currency major economies: infrastructure benefits without deposit substitution risk.

Text summary of current containment controls.
Jurisdiction	Framework	Key containment controls
UAE (CBUAE)	Payment Token Services Regulation	Licensed custodial only; AED-only for retail access; institutional caps [4]
UAE (ADGM)	FSRA Fiat-Referenced Tokens	Licensed activities only; regulated holding; institutional focus [5]
UK (proposed)	BoE Systemic Stablecoin Regime	Proposed GBP20K individual and GBP10M institutional caps; no yield; full redemption rights [6]
Singapore (MAS)	SCS Framework	MAS-regulated issuance; reserve standards; limited yield permissions [7]
Brazil (BCB)	Crypto framework (2023)	Classified as FX instruments; BCB oversight; transit facilitation [1]

Three structural features recur: caps on retail holding, no yield on payment stablecoins, and licensed/custodial access.

The contained features in practice are caps, no yield, and licensed or custodial access. UK proposed caps of GBP20K individual and GBP10M institutional are calibrated to enable payments but prevent savings substitution. UAE CBUAE treatment restricts retail access to AED-denominated tokens, blocking direct USD/EUR retail holding. Contained regimes generally prohibit yield on payment stablecoins. The BoE consultation models zero yield plus a GBP20K cap as a maximum 2-3% deposit outflow, manageable within existing liquidity frameworks. Licensing is the common operating base: UAE requires a VASP license through CBUAE or FSRA authorization through ADGM; the UK proposes FCA authorization; Singapore requires MPI licensing under the Payment Services Act. For corridor operators, no single compliance configuration works across UAE, UK, and Singapore.

The Transit-Only Regimes

The conservative path permits stablecoin activity as a payment rail but not as a held balance.

The most conservative regimes that still enable payment infrastructure permit stablecoin activity only as a payment rail. Licensed operators can on-ramp and off-ramp, but retail users cannot hold balances. The stablecoin exists only during the transit window.

Singapore before SCS and Chile's 2023 fintech law: stablecoins exist only during the transit window.

In a transit-only regime, the stablecoin exists for the payment sequence: fiat in, stablecoin transit, fiat out. Singapore before the SCS framework, from 2019 to 2023, permitted licensed operators to use stablecoins as intermediate settlement without enabling retail balances. Chile codifies a similar architecture in its 2023 fintech-law approach. The operational advantage is low regulatory overhead. There are no deposit insurance questions because there is no holding, no yield treatment because there is no duration, and no holding caps to calibrate. The compliance surface is operator licensing and Travel Rule data exchange during the transit window. Jurisdictions often start here because transit-only is reversible. Singapore used four years of transit-only data before expanding toward contained holding under SCS. If the experiment creates problems, withdrawal is cleaner because there are no retail holders to protect.
