Payment Stablecoin Regulation

Executive Summary

Payment stablecoins -- fiat-referenced digital assets designed for use as a means of payment or settlement -- have become the most heavily regulated category of crypto-asset globally. Between June 2023 and June 2026, a majority of the nineteen jurisdictions analysed in this domain enacted, finalised, or formally proposed dedicated stablecoin regulatory frameworks, each addressing a common set of policy questions: who may issue stablecoins, what reserve assets are permissible, how redemption rights are enforced, and how stablecoin issuance interacts with existing payment licensing regimes.

This section provides a comparative analysis of the five dominant regulatory models that have emerged, a jurisdiction-by-jurisdiction breakdown of requirements, an evidence-based assessment of what works and what does not, and a recommended framework for regulators designing or refining their own stablecoin payment regimes.

The analysis covers all nineteen jurisdictions in this domain: in the Americas, the

US,

Brazil,

Canada, and

El Salvador; in Asia-Pacific,

Australia,

Hong Kong,

India,

Japan,

Singapore, and

South Korea; in Europe, the

EU,

France,

Germany,

Liechtenstein,

Switzerland, and the

UK; and in the Middle East & Africa,

Bahrain,

Nigeria, and the

UAE. Of these, nine have a dedicated or operational payment-stablecoin regime in force (EU, US, Hong Kong, Bahrain, Nigeria, UAE, Japan, Brazil, and -- via EEA MiCA -- France, Germany, and Liechtenstein operate the EU regime nationally), while several others have enacted-but-not-yet-in-force or proposed regimes (Canada, UK, Switzerland, South Korea), and a minority retain no dedicated framework (Australia, India). Data is drawn from the canonical crypto-payment-regulation fact matrix and verified against primary legislative sources, regulator publications, and authoritative legal analyses as of 4 June 2026.

1. Global Landscape -- Regulatory Models

Five distinct regulatory models have emerged for governing payment stablecoins. Each reflects different institutional capacities, market conditions, and policy priorities. No single model is universally superior; the optimal approach depends on a jurisdiction's existing regulatory infrastructure, the maturity of its stablecoin market, and its policy objectives regarding monetary sovereignty and financial inclusion.

Model A: Dedicated Stablecoin Legislation

How it works: The legislature enacts a standalone statute or a distinct title within broader crypto legislation that defines payment stablecoins as a new regulated category, specifies permissible issuers, prescribes reserve and redemption requirements, and establishes a licensing or authorisation regime administered by one or more financial regulators. The stablecoin framework sits alongside, but does not replace, existing payment services and e-money licensing regimes.

Jurisdictions:

EU (MiCA Titles III-IV),

UK (Cryptoassets Regulations 2026 + BoE systemic regime, proposed/not in force),

Hong Kong (Stablecoins Ordinance),

Bahrain (SIO Module),

UAE (CBUAE PTSR + ADGM FRT Framework),

Nigeria (SEC framework under ISA 2025),

Canada (Stablecoin Act, enacted but not yet in force). EU member states

France,

Germany, and

Liechtenstein operate the MiCA EMT/ART regime nationally.

Reserve requirements:

• EU: EMT issuers must deposit at least 30% of received funds in separate accounts at credit institutions; the remainder must be invested in secure, low-risk, highly liquid financial instruments denominated in the reference currency (MiCA Article 54). For significant EMTs, the deposit requirement increases to 60% across multiple credit institutions. ART issuers must maintain reserves covering all outstanding tokens, segregated from issuer assets. EMTs are issuable only by credit institutions or EMD2-authorised EMIs (MiCA Art. 48).
• Hong Kong: 100% reserve backing at all times (reserve market value >= par); reserves must be high quality, high liquidity, minimal risk; reserves may be held outside Hong Kong (multi-jurisdictional permitted); must be segregated through trust arrangements. Minimum paid-up capital of HKD 25 million (waived for authorised banks) plus HKD 3 million liquid capital. Licence required for FRS issuers operating in HK, HKD-pegged FRS issued anywhere, or active marketing to the HK public; at least one-third independent non-executive directors.
• Bahrain: Strict 1:1 reserve backing at all times with cash, AA-rated bank deposits, central bank debt securities, or repos; segregated custodian accounts; annual audits. Par redemption within five business days. Single-currency fiat-backed (BHD/USD/approved) permitted, yield-bearing stablecoins explicitly permitted; whether algorithmic stablecoins are prohibited is NOT VERIFIED. Issuers must be a Bahraini Joint Stock Company (BSC) with a minimum three-year track record.
• UAE: 100% reserves in liquid high-quality assets, at least 50% as cash in UAE banks; redeemable at par within one business day. Dirham Payment Tokens (AED-pegged) require a full CBUAE licence; Foreign Payment Tokens require CBUAE registration (use restricted to VA/derivative purchases). Algorithmic stablecoins and privacy tokens are banned.
• Nigeria: cNGN is 100% backed by Naira reserves at licensed custodian banks, pegged 1:1 to NGN. The SEC framework under ISA 2025 requires verifiable reserves, regular audits, and AML/KYC obligations.
• Canada: 1:1 reserve mandate (assets >= par) in the reference currency plus high-quality liquid assets only, held by qualified custodians in segregated, creditor-protected accounts, with monthly reporting.

Outcomes: Model A provides the highest regulatory clarity for market participants. The EU's MiCA framework has driven the most observable compliance activity: Circle obtained an EMI licence from France's ACPR (effective 1 July 2024), becoming the first global stablecoin issuer to achieve MiCA compliance, while Tether's USDT and PayPal's PYUSD were delisted for EEA users due to non-compliance. As of 12 April 2026 the ESMA interim register showed ~199 authorised CASPs across 23 countries, with 20 EMT issuers and zero ART issuers. Hong Kong received 77 expressions of interest within the first application window and granted its first two stablecoin issuer licences on 10 April 2026 (Anchorpoint Financial -- a Standard Chartered/HKT/Animoca JV -- and HSBC). Bahrain granted its first SIO issuer licence on 3 June 2026 to AX Coin Bahrain B.S.C. (c). The UAE approved USDU (first USD-backed token under the PTSR, January 2026) and gave final approval to the AED-backed DDSC (February 2026). Nigeria's cNGN launched 3 February 2025 as Africa's first regulated stablecoin. The primary risk of Model A is legislative lag -- the UK's dedicated framework will not commence until 25 October 2027, and Canada's Stablecoin Act, though enacted at Royal Assent on 26 March 2026, awaits a Governor-in-Council order (expected 2027) before its substantive provisions take effect.

Model B: Existing Banking/EMI Framework Applied

How it works: Rather than enacting new stablecoin-specific legislation, the jurisdiction interprets stablecoin issuance under existing banking, trust, or payment services law. Stablecoin issuers are required to hold banking licences, trust company licences, or fund transfer service registrations. Reserve and redemption requirements derive from existing prudential rules for these entity types.

Jurisdictions:

Japan (PSA Electronic Payment Instruments framework),

Switzerland (proposed Regulated Stablecoins category under FinIA amendments, October 2025 consultation closed 6 February 2026).

Reserve requirements:

• Japan: Electronic Payment Instruments (EPIs) must be fiat-denominated and redeemable at par on demand, subject to prudential supervision. Only banks, trust companies/trust banks, and registered fund transfer service providers may issue EPIs; distributors register as EPIESPs. Trust-beneficiary issuers may invest up to 50% of reserves in JGBs and US Treasuries (3-month maturity), with the remainder in bank deposits, and customer assets must be fully segregated. From 1 June 2026, a Cabinet Office Ordinance recognises qualifying foreign trust-type stablecoins as EPIs under the PSA (handled by registered EPIESPs on a case-by-case JFSA assessment, rather than treated as FIEA securities).
• Switzerland (proposed): Regulated Stablecoins would be issuable exclusively by licensed payment instrument institutions; single fiat-currency peg only; banks could not directly issue (a separate payment-institution subsidiary would be required). Reserves would be fully backed and segregated, held only as bank sight deposits or high-quality liquid assets, redeemable at par, with FINMA maintaining a regulatory list. A mandatory whitepaper would be required. Pending enactment, AMLA almost always applies to stablecoin issuers, and full backing / redemption-at-par follows FINMA Guidance 06/2024.

Outcomes: Model B leverages existing supervisory infrastructure and avoids the legislative effort of creating new regimes. Japan operationalised one of the world's first stablecoin regimes (PSA 2022 amendments, effective 1 June 2023). SBI VC Trade became the first registered EPIESP, distributing USDC from March 2025; JPYC Inc. became the first yen-stablecoin issuer (registered 18 August 2025, launched 27 October 2025); and the megabank Project Pax (MUFG/SMBC/Mizuho on Progmat/Datachain) and SBI Shinsei JPYSC are maturing through 2026, with Project Pax targeting ~JPY 1 trillion in circulation by 2028. The constraint of Model B is the limitation on issuer types -- restricting issuance to banks and trust companies may exclude fintech innovators and increase barriers to entry. Japan's practical startup cost for a CAESP is estimated at over JPY 1 billion (~USD 6.7 million). Switzerland's proposed FinIA reform is not expected to enter into force before 2027 (some analyses suggest 2028).

Model C: Proposed/Enacted Federal Legislation

How it works: A jurisdiction with a fragmented or multi-regulator structure enacts new federal legislation to create a unified stablecoin framework, while preserving a role for existing sub-national regulators. The federal statute defines stablecoin categories, permissible issuers, reserve requirements, and oversight responsibilities, and may preempt certain state or provincial laws.

Jurisdictions:

US (GENIUS Act, enacted 18 July 2025).

Reserve requirements: Issuers must maintain reserves on a 1:1 basis using only permitted reserve assets: cash, US Treasury bills (93-day maturity or less), Treasury-backed repos, and government money market funds. Rehypothecation is prohibited. No interest or yield may be paid to stablecoin holders. Reserves must be segregated and commingling with issuer funds is prohibited. Monthly public reserve disclosure and plain-language redemption procedures are required.

Issuer categories:

1. Insured Depository Institution Subsidiaries -- supervised by the primary federal banking regulator; no cap on issuance.
2. Federal Qualified Payment Stablecoin Issuers (FQPSIs) -- nonbank entities chartered by the OCC; preempts state chartering requirements.
3. State Qualified Payment Stablecoin Issuers (SQPSIs) -- state-chartered; capped at USD 10 billion in outstanding stablecoins; the state framework must be certified as "substantially similar" to federal requirements, with transition to federal oversight once the threshold is exceeded.

Outcomes: The GENIUS Act resolved a multi-year regulatory vacuum in the world's largest financial market. Regulations are due by 18 July 2026, and the Act becomes effective on the earlier of 18 January 2027 or 120 days after final rules. As of June 2026, six of the seven implementing regulators had issued proposed rules, with the Federal Reserve Board's NPRM still pending: the OCC NPRM (Bulletin 2026-3, 25 February 2026); the Treasury "substantially similar" state-regime principles NPRM (3 April 2026); an FDIC substantive NPRM (7 April 2026, with a USD 5M de novo floor and 2-business-day redemption); the joint FinCEN/OFAC PPSI AML/CFT and sanctions NPRM (10 April 2026); and the NCUA operational/risk-management NPRM (15 May 2026). Circle received conditional OCC approval for a national trust bank charter, and Wyoming launched the Frontier Stable Token (FRNT) in August 2025 -- the first state-issued stablecoin. (The separate market-structure bill -- the Digital Asset Market Clarity Act (CLARITY Act, H.R. 3633), advanced by the Senate Banking Committee on 14 May 2026 -- remains not enacted and is distinct from the GENIUS Act's payment-stablecoin scope.) The USD 10 billion cap on state-qualified issuers is a novel tiered approach that balances federalism with systemic-risk management.

Model D: Central Bank-Led / FX Classification

How it works: The central bank assumes primary or exclusive regulatory authority over stablecoin activity, often classifying stablecoins under existing monetary or foreign exchange frameworks rather than creating new licensing categories. This model is common in jurisdictions where the central bank has broad financial regulatory powers.

Jurisdictions:

Brazil (BCB Resolution 521),

South Korea (proposed Digital Asset Basic Act classifying stablecoins as FX-payment instruments, not enacted).

Reserve requirements:

• Brazil: BCB Resolution 521 classifies fiat-referenced stablecoin transactions as foreign exchange (FX) operations. Issuance requires full backing in fiat currency or public-debt securities, and algorithmic stablecoins are banned (Resolution 520, which also imposes a restrictive "fiat-referenced virtual asset" definition and requires self-hosted wallet owners to be identified). The same AML/CFT, reporting, and conduct requirements that apply to traditional FX transactions apply to stablecoin purchases, sales, and transfers, with monthly FX-reporting from 4 May 2026. Stablecoins account for approximately 90% of Brazil's crypto transaction volume (per BCB chief Galipolo).
• South Korea (proposed): The Digital Asset Basic Act (introduced 8 April 2026, not enacted) would classify stablecoins as payment instruments under the Foreign Exchange Transactions Act, require 100%+ reserves in high-quality assets (bank deposits/government bonds), mandate full redemption rights and customer-fund segregation, and prohibit yield on idle balances. A bank-versus-fintech issuer dispute (the Bank of Korea favours a 51% bank-ownership requirement; the FSC opposes) remains unresolved, and stablecoin-issuer capital thresholds vary across drafts (KRW 5bn to KRW 50bn).

Outcomes: Brazil's approach is pragmatic -- by classifying stablecoins under the existing FX regime rather than creating new categories, the BCB leverages its existing supervisory capacity and avoids legislative delay. The framework took effect 2 February 2026 with a 270-day grandfathering period (existing operators must apply/notify by 30 October 2026). A bifurcated structure has emerged: Resolution 561 (effective 1 October 2026) bans crypto/stablecoin settlement in the regulated eFX cross-border rails, but licensed SPSAV/bank stablecoin rails under Resolution 521 remain permitted. The risk is regulatory over-reach: treating domestic BRL-pegged stablecoin transactions as FX operations may create friction for purely domestic use cases. In South Korea, the Digital Asset Basic Act was left off the bill-review subcommittee agenda on 12 May 2026 and deferred past the 3 June 2026 local elections, with deliberations expected to resume in H2 2026.

Model E: No Dedicated Framework

How it works: The jurisdiction has not enacted stablecoin-specific regulation. Stablecoin issuance and use may fall under general financial services regulation, AML/CTF requirements, securities/financial-product law, or may be effectively unregulated. This creates uncertainty for issuers and users.

Jurisdictions:

Australia (no dedicated stablecoin regime; captured by overlapping AUSTRAC/ASIC/RBA frameworks, with stablecoin-trading platforms brought under the AFSL Digital Asset Platform regime once it commences 9 April 2027),

India (no stablecoin regime; the RBI argues CBDCs should be prioritised over private stablecoins, per its December 2025 Financial Stability Report).

Outcomes: Model E jurisdictions risk becoming destinations for regulatory arbitrage and deprive consumers of statutory redemption rights, reserve transparency, and recourse mechanisms. Australia's case is transitional rather than permissive: a stablecoin may be a financial product requiring an AFSL/PDS, and the enacted (not-yet-commenced) Digital Assets Framework Act 2026 will bring stablecoin-trading platforms under AFSL licensing. India's stance is effectively prohibitive-by-economics -- a 30% flat tax plus 1% TDS makes crypto-as-payment unviable -- with no dedicated stablecoin issuer rules. The FSB's high-level recommendations and ongoing IOSCO consultations continue to push Model E jurisdictions toward adopting at least minimum standards.

2. Comparative Analysis Table

The following table compares the stablecoin payment regulatory frameworks of the jurisdictions with active, enacted, or formally proposed regimes. Data is drawn from the canonical fact matrix and verified regulatory publications as of 4 June 2026. (Australia and India are omitted from the table as they have no dedicated stablecoin regime; France, Germany, and Liechtenstein operate the EU MiCA EMT/ART regime nationally and are represented by the EU column.)

3. What Works and What Does Not

3.1 Evidence-Based Assessment of Reserve Requirements

What works: Prescriptive asset composition with central bank deposit floors.

The BoE's proposed requirement of ~40% unremunerated central bank deposits for systemic stablecoins represents the most conservative approach and directly addresses the "run risk" that concerns prudential regulators. By mandating that a substantial portion of reserves be held at the central bank, the BoE ensures that systemic stablecoin issuers have immediate access to the most liquid asset possible -- central bank money -- during periods of stress. The

EU's tiered approach (30% for standard EMTs, 60% for significant EMTs) provides a proportionate alternative.

The

US GENIUS Act's prohibition on rehypothecation is a critical safeguard. Tether's historical practice of lending reserve assets and holding commercial paper was a primary source of market concern. By explicitly prohibiting rehypothecation and limiting reserves to cash, short-dated US Treasuries, Treasury-backed repos, and government money market funds, the GENIUS Act eliminates a major source of counterparty risk.

What does not work: Unspecified "high-quality liquid asset" requirements without composition floors.

Hong Kong's Stablecoins Ordinance requires reserves to be "high quality, high liquidity, minimal risk" but does not prescribe specific composition thresholds or mandate central bank deposits. While the HKMA retains discretion to impose conditions on individual licensees (and granted only two licences in its first batch, to Anchorpoint Financial and HSBC), the absence of a statutory composition floor creates inconsistency risk across issuers.

Singapore's framework similarly specifies "high-quality liquid assets in the pegged currency" without a deposit floor, though MAS's direct supervisory oversight of a small number of approved issuers (Paxos, StraitsX) mitigates this risk in practice. The UAE's PTSR is more prescriptive on this point, requiring at least 50% of reserves to be held as cash in UAE banks.

3.2 Redemption Rights

What works: Statutory redemption at par, unconditional, free of charge.

The EU's approach under MiCA Article 49 is the gold standard: EMT holders have a permanent, unconditional claim to redeem at par value, free of charge, at any time. No contractual provision may restrict or charge for redemption. This creates a clear, enforceable consumer right that exists independently of the issuer's terms and conditions.

The

US GENIUS Act provides statutory redemption rights and plain-language redemption procedures; the FDIC's April 2026 NPRM proposes a two-business-day redemption standard for insured-depository issuers. The

UAE mandates the fastest cycle -- redemption at par within one business day -- while

Japan requires redemption at par on demand, and

Singapore and

Bahrain both specify a five-business-day window that gives issuers operational flexibility while ensuring timely access for holders.

What does not work: Redemption rights that exist only in contractual terms.

In jurisdictions without dedicated stablecoin legislation (Model E), redemption rights exist only in the issuer's terms of service. These can be modified unilaterally, may include fees, and may be difficult to enforce cross-border. The absence of statutory redemption rights was a significant factor in the run on TerraUSD (UST) in May 2022 -- holders had no legal claim to redemption and no regulatory recourse.

3.3 Issuer Eligibility and Licensing

What works: Tiered issuer categories proportionate to systemic importance.

The US GENIUS Act's three-tier structure (IDI subsidiaries, federal qualified issuers, state qualified issuers with a $10B cap) is a well-designed approach that accommodates different business models while managing systemic risk. The $10 billion threshold for state-qualified issuers creates a natural transition point to federal oversight as an issuer grows.

The

UK's dual-regulator model (FCA for non-systemic, BoE for systemic) similarly provides proportionate oversight -- small stablecoin issuers face lighter FCA requirements, while systemically important issuers face BoE prudential standards equivalent to banking supervision.

Japan's restriction to banks, trust companies, and fund transfer service providers ensures that all issuers are subject to existing prudential supervision but limits market entry; the practical cost of JPY 1 billion+ (~USD 6.7 million) to establish a CAESP represents a significant barrier.

Bahrain's requirement that issuers be a Bahraini Joint Stock Company with a three-year track record is similarly conservative on entity type.

What does not work: Uniform requirements regardless of scale.

Hong Kong's HKD 25 million minimum capital applies to all stablecoin issuers regardless of size. While reasonable for the Hong Kong market (which the HKMA expects will produce only a handful of licensed issuers), this approach would be disproportionate in larger markets with diverse issuer populations. Brazil's SPSAV capital requirements of R$10.8 million to R$37.2 million and Nigeria's sharply increased Circular 26-1 thresholds (NGN 2bn for DAX/custodian categories) are similarly high for emerging markets and risk excluding smaller local operators.

3.4 Interaction with Traditional Payment Licensing

What works: Simplified pathways for MiCA-licensed firms to obtain payment authorisation.

The EU's experience with the MiCA-PSD2 dual licensing overlap is the most instructive case study in this area. When MiCA's CASP provisions took effect on 30 December 2024, it became unclear whether CASPs providing EMT custody and transfer services also needed PSD2 authorisation. The EBA's June 2025 No-Action Letter provided temporary relief, but from 2 March 2026, CASPs providing EMT transfer/custody services that constitute payment services must hold PSD2 PI or EMI authorisation. PSD3/PSR (COREPER-endorsed compromise texts, 22 April 2026; OJ publication anticipated mid-2026) promises a simplified authorisation pathway for MiCA-licensed CASPs.

What does not work: Leaving the stablecoin-payment licensing intersection unaddressed.

Jurisdictions that have not explicitly addressed whether stablecoin transfers constitute "payment services" under existing frameworks create compliance uncertainty. The UK's decision to keep stablecoins outside the Payment Services Regulations 2017 leaves a regulatory gap until the full cryptoasset regime commences on 25 October 2027. During this interim period, stablecoin payments are neither regulated as payment services nor (for most purposes) as cryptoasset activities.

3.5 Cross-Border Recognition

What works: EU passporting under MiCA.

MiCA's passporting mechanism (Articles 59(7), 65) allows CASPs authorised in one EU/EEA Member State to provide services across all Member States via notification. Circle's French EMI licence enables USDC and EURC distribution across the entire EU/EEA from a single authorisation, and EEA membership similarly lets

Liechtenstein-authorised issuers passport EU-wide. The

UAE's CMA-VARA unified register provides a more limited form of mutual recognition, enabling cross-emirate VASP operation within the federation.

What does not work: Fragmentation everywhere else.

No jurisdiction outside the EU/EEA offers true cross-border passporting for stablecoin issuers or service providers. The US requires separate state licences absent a federal charter,

Japan requires full JFSA registration with local incorporation,

Singapore requires an MPI licence with Singapore incorporation, and the

UK requires separate FCA authorisation with no EU equivalence post-Brexit. This fragmentation imposes substantial compliance costs on global stablecoin issuers -- Circle, for example, must maintain separate authorisations across the US, EU, Singapore, and (prospectively) the UK and other markets.

3.6 Significant Stablecoin Thresholds

What works: Graduated oversight based on usage metrics.

MiCA's significance criteria for EMTs (Article 43) -- triggered when at least three of several thresholds are met (e.g., 10M+ holders, EUR 5B+ market cap, 2.5M+ daily transactions, EUR 500M+ daily volume) -- provide a data-driven mechanism for escalating supervision. When an EMT is classified as significant, the EBA assumes direct supervisory responsibility, reserve deposit requirements increase from 30% to 60%, and enhanced liquidity management and stress testing apply.

The US GENIUS Act's $10 billion threshold for state-qualified issuers serves a similar graduated function, triggering mandatory transition to federal oversight.

What does not work: Binary frameworks with no intermediate tier.

Japan,

Hong Kong,

Bahrain, and

Brazil apply essentially uniform requirements to all stablecoin issuers regardless of scale. While Hong Kong's market structure (few expected licensees) makes this practical, jurisdictions with diverse issuer populations benefit from tiered requirements that match regulatory intensity to systemic importance.

4. Recommended Framework

Based on the comparative evidence from the jurisdictions analysed, the following tiered framework is recommended for regulators designing or refining payment stablecoin regimes. Each recommendation cites the jurisdiction(s) whose experience supports it.

Tier 1: Definitional Foundation

Define "payment stablecoin" narrowly and functionally.

• Limit scope to single fiat-referenced tokens designed for payment or settlement use. Exclude algorithmic stablecoins, multi-asset tokens, and yield-bearing instruments from the payment stablecoin category. Precedent: MiCA EMT definition (Art 3(1)(7)); Singapore SCS framework (single-currency, SGD/G10); UK "qualifying stablecoin" definition; Brazil and UAE expressly ban algorithmic stablecoins.
• Bahrain's decision to permit yield-bearing stablecoins within its framework is a notable outlier. Regulators should consider whether yield-bearing features transform a payment instrument into an investment product, potentially requiring separate regulatory treatment.

Tier 2: Issuer Eligibility

Restrict issuance to regulated entities, with proportionate categories.

• Require stablecoin issuers to hold a financial licence (banking, e-money, payment institution, or dedicated stablecoin licence). Precedent: every jurisdiction with a dedicated regime requires licensing; no Model E jurisdiction has produced a successful domestic stablecoin market.
• Create at least two issuer tiers based on outstanding stablecoin value:
  • Standard issuers (below a defined threshold): Subject to conduct and reserve requirements with regular NCA supervision. Precedent: MiCA non-significant EMT issuers; US SQPSIs (under $10B); UK non-systemic issuers under FCA.
  • Significant/systemic issuers (above the threshold): Subject to enhanced prudential requirements, higher reserve deposit floors, stress testing, and potential central bank supervision. Precedent: MiCA significant EMT regime (EBA supervision); UK systemic stablecoin regime (BoE supervision); US transition to federal oversight above $10B.

Tier 3: Reserve and Redemption Standards

Mandate prescriptive reserve composition with central bank or bank deposit floors.

• Require 1:1 reserve backing at all times -- this is universal across all dedicated regimes studied and is non-negotiable for payment stablecoin credibility. Precedent: unanimous across every dedicated regime.
• For standard issuers, require a meaningful share of reserves in bank deposits (preferably at multiple institutions) with the remainder in short-duration government securities or central bank debt. Precedent: MiCA Article 54 (30% minimum); UAE PTSR (>=50% cash in domestic banks).
• For significant/systemic issuers, increase the deposit floor to 40-60%, ideally including central bank deposits where available. Precedent: BoE proposed ~40% central bank deposit; MiCA 60% for significant EMTs.
• Prohibit rehypothecation of reserves. Precedent: US GENIUS Act (explicit prohibition); implicit in most other frameworks.
• Require segregation of reserves from issuer assets through trust arrangements or equivalent ring-fencing held by qualified custodians. Precedent: unanimous across all dedicated regimes (e.g. Hong Kong trust segregation; Canada qualified-custodian creditor-protected accounts).

Establish statutory redemption rights.

• Grant holders an unconditional statutory right to redeem at par value. Precedent: MiCA Article 49; US GENIUS Act; UK proposed regime; Canada Stablecoin Act.
• Set a maximum redemption timeframe, calibrated to the market. Precedent: UAE (1 business day); Singapore and Bahrain (5 business days); Japan (on demand); US FDIC NPRM (2 business days).
• Prohibit fees on redemption, or cap them at a de minimis level. Precedent: MiCA (free of charge); US GENIUS Act (plain-language procedures, no unreasonable fees).

Tier 4: Disclosure and Transparency

Require regular, public reserve reporting.

• Monthly public disclosure of reserve composition, audited or independently verified. Precedent: US GENIUS Act (monthly); Singapore (monthly independent checks + annual audit); Canada (monthly reporting); Brazil (monthly FX-reporting under Resolution 521).
• Annual audited financial statements and independent reserve audits. Precedent: Bahrain (annual audits); Singapore (annual audit); Hong Kong.
• A crypto-asset white paper describing the stabilisation mechanism, reserve management policy, redemption procedures, and risk factors. Precedent: MiCA (mandatory white paper); Hong Kong, Bahrain, and Switzerland (proposed) all require a whitepaper.

Tier 5: Interaction with Payment Licensing

Address the stablecoin-payment services overlap explicitly from the outset.

• Determine whether stablecoin transfers constitute "payment services" under existing payment legislation. If yes, provide a simplified authorisation pathway for firms already holding stablecoin issuance or CASP licences. Precedent: EU PSD3/PSR (simplified pathway for MiCA CASPs); avoid the EU's 2024-2026 dual-licensing confusion.
• If the jurisdiction has a comprehensive stablecoin framework, consider exempting stablecoin-specific activities from general payment services licensing, provided the stablecoin framework imposes equivalent or greater consumer protection. Precedent: UK decision to keep stablecoins outside the PSRs 2017, though this created an interim gap.

Tier 6: Cross-Border and Monetary Sovereignty

Address non-domestic currency stablecoins explicitly.

• For stablecoins denominated in foreign currencies (e.g., USD stablecoins circulating in non-US markets), consider usage caps to protect monetary sovereignty. Precedent: MiCA non-euro EMT usage caps (1 million transactions / EUR 200M daily volume within the euro area); UAE restricts Foreign Payment Tokens to VA/derivative purchases.
• Alternatively, classify foreign-currency stablecoin transactions under existing FX frameworks. Precedent: Brazil Resolution 521 (stablecoins as FX operations); South Korea's proposed FX-Transactions-Act classification.
• Explore mutual recognition or equivalence arrangements with jurisdictions whose stablecoin frameworks meet comparable standards. Precedent: the EU's MiCA passporting and the UAE's CMA-VARA unified register demonstrate the value of cross-border portability within a harmonised perimeter.

5. Decision Matrix

The following matrix is designed for regulators choosing between the five regulatory models. Each cell indicates the relative suitability (High / Medium / Low) of a model for a given policy objective.

Recommended Selection Criteria

Choose Model A (Dedicated Legislation) if:

• The jurisdiction has legislative capacity and political will for new financial services legislation.
• The stablecoin market is or is expected to become materially significant (multiple issuers, retail adoption).
• The jurisdiction seeks to attract stablecoin issuers as part of a broader digital finance strategy.
• Examples: EU, UK, Hong Kong, Bahrain, UAE, Nigeria, Canada.

Choose Model B (Existing Framework) if:

• The jurisdiction has a mature, well-functioning banking and payment services regulatory framework.
• The primary policy concern is ensuring stablecoins are as safe as existing bank deposits or e-money.
• Legislative reform is slow or politically difficult.
• Examples: Japan, Switzerland (transitioning toward a dedicated category).

Choose Model C (Federal Legislation) if:

• The jurisdiction has a multi-regulator or federated structure requiring harmonisation.
• State/provincial regulators are already active in stablecoin licensing, creating fragmentation.
• The jurisdiction is a major stablecoin market requiring federal-level coordination.
• Example: United States.

Choose Model D (Central Bank-Led / FX) if:

• The central bank has broad financial regulatory authority.
• Stablecoins are primarily used for cross-border payments or FX-substitute purposes.
• The jurisdiction is pursuing a CBDC that may interact with or compete with private stablecoins.
• Examples: Brazil, South Korea (proposed).

Avoid Model E (No Framework) in all cases. The FSB's high-level recommendations, FATF standards, and BIS/CPMI principles all call for jurisdictions to regulate stablecoin activities. Failure to do so creates consumer risk, AML/CFT gaps, and regulatory arbitrage opportunities. Australia and India illustrate the transitional and prohibitive-by-economics variants of this position respectively.

6. Key Cross-Cutting Issues

6.1 Reserve Composition -- The Central Question

The single most consequential design choice in stablecoin regulation is the composition of permitted reserve assets. The spectrum ranges from Brazil's FX classification (which effectively requires compliance with existing FX reserve norms) to Bahrain's framework (which permits yield-bearing stablecoins backed by reserves earning interest). The key trade-offs are:

• Higher liquidity requirements (more bank deposits, central bank deposits) reduce run risk but lower issuer profitability and may make stablecoin issuance economically unviable for smaller players.
• Permitting government securities in reserves (as the US, EU, UK, Japan, Singapore, and South Korea's proposal all do) provides a balance between safety and yield, but introduces duration and market risk -- short-duration limits (<=93 days under GENIUS Act; 3-month maturity under Japan's trust model) mitigate this.
• Rehypothecation prohibition (explicit in the GENIUS Act; implicit in most frameworks) is critical. The 2022-2023 concerns about Tether's reserve composition demonstrated that stablecoin reserves are not equivalent to bank deposits if the issuer can lend or pledge them.

6.2 The EMI/PI Overlap

The interaction between stablecoin regulation and existing payment services / e-money licensing is the most technically complex aspect of stablecoin regulation. The EU's experience provides the clearest case study:

1. June-December 2024: MiCA stablecoin and CASP provisions take effect, but the relationship with PSD2 is ambiguous.
2. June 2025: EBA issues a No-Action Letter, advising NCAs to deprioritise enforcement of PSD2 requirements for CASPs providing EMT transfer services until 2 March 2026.
3. 2 March 2026: Transition period ends; CASPs whose EMT transfer/custody activities are payment services must hold PSD2 authorisation. National transition periods for pre-MiCA providers expire 1 July 2026.
4. 2026: PSD3/PSR (COREPER-endorsed 22 April 2026) expected to simplify the framework by offering a streamlined pathway for MiCA CASPs.

This period of uncertainty imposed significant compliance costs on EU crypto firms. Regulators designing new frameworks should explicitly address the overlap from day one, rather than relying on post-hoc supervisory guidance. Precedent: Licensing Frameworks analysis.

6.3 Yield Prohibition vs. Permission

The near-universal prohibition on paying yield to stablecoin holders (adopted by the EU, US, UK, Singapore, Japan, Switzerland's proposal, and South Korea's proposal) reflects a policy choice to classify payment stablecoins as a "means of payment" rather than an "investment product." If holders earn yield, the stablecoin begins to resemble a deposit or a collective investment scheme, triggering different regulatory treatment.

Bahrain's decision to permit yield-bearing stablecoins is a deliberate policy divergence, designed to attract issuers and reflect the economic reality that reserves generate returns. If yield is permitted, regulators should impose safeguards: the yield must not adversely affect the stability of the approved stablecoin, and yield-bearing stablecoins may warrant higher capital or reserve requirements. (Hong Kong's and the UAE's positions on yield to holders are NOT VERIFIED at statute level.)

6.4 Non-Compliant Stablecoin Sunset Provisions

Both the

EU and

US have established mechanisms to phase out non-compliant stablecoins:

• EU: Tether USDT and PayPal PYUSD were delisted for EEA users (H2 2024-Q1 2025) following failure to obtain EMI authorisation. ESMA confirmed a uniform 1 July 2026 end to transitional periods, with wind-down plans required.
• US: The GENIUS Act mandates that digital asset service providers cease offering non-compliant stablecoins once the regime is fully effective.

These sunset provisions are essential for regulatory effectiveness. Without them, compliant issuers bear the full cost of licensing while non-compliant issuers continue to operate -- creating a regulatory penalty for compliance.

6.5 CBDC Interaction

Several jurisdictions are simultaneously developing both stablecoin frameworks and CBDCs:

• Brazil: the
  Drex CBDC pivoted away from blockchain (Aug 2025) and targets a 2026 launch, positioned as complementary to -- not a replacement for -- private stablecoins.
• Hong Kong: the e-HKD Pilot Phase 2 report was published October 2025; the HKMA is prioritising wholesale e-HKD while private stablecoins address retail use cases.
• UAE: the Digital Dirham (wholesale + retail) is advancing alongside the PTSR, including cross-border settlement via mBridge.
• UK: the BoE's digital pound work and atomic-settlement ambition (targeted 2028) run in parallel with the systemic stablecoin regime.

The relationship between regulated stablecoins and CBDCs is not necessarily competitive. Well-designed stablecoin frameworks can complement CBDCs by providing private-sector innovation within regulated boundaries, while CBDCs provide the ultimate risk-free settlement layer. (India's RBI takes the opposite view, arguing that CBDCs should be prioritised over private stablecoins.)

6.6 Consumer Asset Segregation and Insolvency Protection

A critical but often under-addressed question is what happens to stablecoin holders when an issuer becomes insolvent. The approaches vary significantly:

• Japan provides among the strongest protections: customer fiat must be held in trust (ring-fenced from insolvency), at least 95% of customer crypto must be in cold wallets with the hot-wallet portion fully backed by the issuer's own cold-stored assets, and an annual segregation audit applies. The DMM Bitcoin hack (May 2024, ~USD 305 million) tested this framework -- accounts were transferred to SBI VC Trade.
• EU MiCA requires reserve segregation from issuer assets and custody with third-party custodians, providing structural separation in insolvency; EMT holders have a permanent claim against the issuer at par value.
• Canada's Stablecoin Act requires reserves to be held by qualified custodians in segregated, creditor-protected accounts.
• US GENIUS Act mandates segregation and prohibits commingling; the interaction with the Bankruptcy Code for in-flight stablecoin transactions remains legally untested.
• UK proposes trust-based segregation for systemic stablecoin backing assets but has explicitly noted that FSCS deposit protection will NOT extend to stablecoins, creating an asymmetric protection regime relative to bank deposits.

Regulators should ensure that their stablecoin frameworks provide clear statutory priority for stablecoin holders over general creditors in insolvency, and require reserve assets to be held in trust or equivalent segregated arrangements that survive the issuer's bankruptcy.

6.7 AML/CFT and the Travel Rule for Stablecoin Transfers

All jurisdictions with a dedicated regime require stablecoin service providers to comply with AML/CFT obligations, but implementation of the FATF Travel Rule for stablecoin transfers varies:

• EU Transfer of Funds Regulation (TFR): Regulation (EU) 2023/1113 applies the Travel Rule to all crypto-asset transfers with no de minimis threshold for CASP-to-CASP transfers (since 30 December 2024); unhosted-wallet ownership verification applies above EUR 1,000.
• Japan: Travel Rule implemented with no minimum threshold (JVCEA rules from April 2022; statutory guidelines clarified 30 December 2024).
• UK: Travel Rule implemented from 1 September 2023 with no minimum threshold -- stricter than the FATF's recommended USD 1,000 threshold.
• US: FinCEN Travel Rule applies to transactions of USD 3,000 or more (31 CFR 1010.410(f)).
• Brazil: Phased implementation over two years (Phase 1 from 2 February 2026; full compliance from 2 February 2028).
• Singapore: Travel Rule implemented under MAS Notice PSN02; enhanced PII required for transfers of S$1,500 or more.
• UAE: VARA fully implemented the Travel Rule from 19 June 2025 (Rulebook v2.0), with a threshold of AED 3,500 (~USD 953); CBUAE operates its own VA Travel Rule.
• Nigeria: Travel Rule being implemented via the CBN's April 2026 VASP AML/CFT supervisory pilot.

The technical challenge of transmitting Travel Rule data alongside on-chain stablecoin transfers remains significant. Regulators should specify acceptable compliance protocols and consider phased implementation to avoid disrupting legitimate stablecoin payment flows.

7. Implementation Timeline Comparison

Verification Notes

This refresh mirrors tier-2 (payment-stablecoin) facts from the canonical crypto-payment-regulation fact matrix across all nineteen jurisdictions, as of 4 June 2026. No new web research was performed; all facts derive from the matrix and the prior verified version of this file. "X of N" aggregates are re-derived from the matrix.

Key Facts Reflected in This Refresh

1. US GENIUS Act implementation (6 of 7 regulators): As of June 2026, six of the seven implementing regulators have issued proposed rules -- OCC (Bulletin 2026-3, 25 Feb 2026), Treasury "substantially similar" principles (3 Apr 2026), FDIC ($5M de novo floor, 2-business-day redemption, 7 Apr 2026), joint FinCEN/OFAC PPSI NPRM (10 Apr 2026), and NCUA (15 May 2026) -- with the Federal Reserve Board's NPRM still pending. Effective on the earlier of 18 Jan 2027 or 120 days after final rules.
2. US market-structure bill correction: The federal market-structure bill is the Digital Asset Market Clarity Act (CLARITY Act, H.R. 3633) (Senate Banking Committee advanced 14 May 2026, not enacted) -- NOT "FIT21." It is distinct from the GENIUS Act and outside the payment-stablecoin scope.
3. EU MiCA EMT rules: >=30% credit-institution deposits (60% for significant EMTs) + HQLA remainder (Art. 54); at-par redemption free of charge any time (Art. 49); issuers limited to credit institutions/EMIs (Art. 48); non-EUR EMT usage caps (1M tx / EUR 200M daily). PSD2/MiCA EMT transition ended 2 March 2026; ~199 CASPs, 20 EMT issuers, 0 ART issuers (12 Apr 2026).
4. Hong Kong: First two Stablecoins Ordinance issuer licences granted 10 April 2026 (Anchorpoint Financial; HSBC) after 77 expressions of interest. Yield-to-holders position remains NOT VERIFIED at statute level.
5. Bahrain: First SIO issuer licence granted to AX Coin Bahrain B.S.C. (c) on 3 June 2026; yield-bearing stablecoins permitted; algorithmic-prohibition status NOT VERIFIED.
6. UAE: USDU (USD-backed, approved Jan 2026) and DDSC (AED-backed, final CBUAE approval Feb 2026) under the PTSR/FRT frameworks; algorithmic stablecoins and privacy tokens banned.
7. Japan: PSA EPI regime in force since June 2023; Cabinet Office Ordinance recognising qualifying foreign trust-type stablecoins as EPIs effective 1 June 2026.
8. Brazil: Resolution 521 (stablecoins-as-FX) in force 2 Feb 2026; MP 1303's flat 17.5% crypto tax was REJECTED (251-193) and expired Oct 2025 -- never in force; the progressive 15%-22.5% regime with a R$35,000 monthly exemption remains. Resolution 561 eFX crypto-settlement ban effective 1 Oct 2026 (licensed SPSAV/bank rails under 521 remain permitted).
9. El Salvador: Bitcoin is no longer legal tender -- a voluntary payment method since Decree No. 199 (29-30 January 2025) under the USD 1.4B IMF EFF; stablecoin issuance regulated by CNAD under LEAD (DASP licence), reserve composition NOT VERIFIED. (El Salvador has no dedicated stablecoin reserve regime and is therefore not in the comparative table.)
10. Canada: Stablecoin Act (Bill C-15, Div. 45 Pt. 5) received Royal Assent 26 March 2026 but substantive provisions are not yet in force (Governor-in-Council order expected 2027); USDC remains the principal CSA-approved stablecoin.
11. South Korea: Digital Asset Basic Act (introduced 8 April 2026) would classify stablecoins as FX-payment instruments with 100%+ reserves, full redemption, and a yield-on-idle-balances ban -- proposed, not enacted; deferred past the 3 June 2026 local elections.
12. Switzerland: Regulated Stablecoins category proposed under FinIA (Oct 2025 consultation, closed 6 Feb 2026); pending enactment, AMLA and FINMA Guidance 06/2024 apply.
