1. Global Landscape
The question of when a stablecoin becomes "too big to fail" -- and what additional regulatory obligations attach at that point -- is the central unresolved challenge of stablecoin governance. As of mid-2026, the stablecoin economy exceeds $315 billion, with a single issuer (Tether/USDT) holding approximately $184 billion in market capitalisation. The potential for a stablecoin failure to cascade through both crypto markets and traditional finance is no longer theoretical: the Terra/LUNA collapse of May 2022 erased over $60 billion and triggered a chain of bankruptcies (Three Arrows Capital, Celsius Network, Voyager Digital, BlockFi, and ultimately FTX), while the USDC depeg of March 2023 demonstrated that even a well-reserved stablecoin can temporarily lose its peg when a custodian bank (Silicon Valley Bank) fails.
Across the 18 national/regional jurisdictions tracked in this repository (plus six international frameworks), only three operate a designation regime built on fixed quantitative thresholds, three rely on discretionary case-by-case designation, and the remaining majority have no stablecoin-specific systemic-risk tier at all. These approaches fall into the following categories.
1.1 Threshold-Based Designation
These jurisdictions define quantitative criteria that, once met, trigger enhanced regulatory requirements and/or a shift in supervisory authority.
European Union (MiCA) operates the most developed threshold-based system. Articles 43-44 (for ARTs) and Articles 56-57 (for EMTs) of Regulation (EU) 2023/1114 establish that a token is designated "significant" if it meets at least three of six criteria, including quantitative thresholds of more than 10 million holders, EUR 5 billion in issued value/market cap/reserves, 2.5 million daily transactions, and EUR 500 million in daily transaction value, plus qualitative international-scale and interconnectedness indicators. Designation triggers EBA direct supervision (ARTs) or joint EBA/NCA supervision (EMTs), higher own funds (up to 3% of reserve assets), a minimum 60% of reserves in bank deposits, and 40%/60% one-day/five-day liquidity buffers.
United States (GENIUS Act) establishes a size-based tiered system under the GENIUS Act (S.1582), which was enacted on 18 July 2025 but is not yet effective (it takes effect on the earlier of 18 January 2027 or 120 days after final implementing rules; no final rule existed as of June 2026). State-qualified issuers exceeding $10 billion in consolidated outstanding stablecoins must notify the OCC within 5 days and transition from the state to the federal framework within 360 days or cease net new issuance. Issuers above $25 billion become subject to large-issuer reserve rules, and issuers above $50 billion must submit audited annual financial statements. The Stablecoin Certification Review Committee (SCRC) certifies state regimes as "substantially similar." Throughout April–May 2026 the implementing NPRMs advanced -- the OCC's comprehensive NPRM (25 February 2026), the FDIC prudential NPRM (7 April 2026, proposing two-business-day redemption), and a joint FinCEN/OFAC AML-CFT and sanctions NPRM (8 April 2026) -- and Tether launched USAT, a GENIUS-compliant US stablecoin via Anchorage Digital Bank (27 January 2026), coexisting with global USDT.
Australia is developing a threshold system under its Tranche 1 Payment Services Provider package. The exposure draft released 12 March 2026 (consultation closed 9 April 2026, not yet enacted) proposes that issuers of major stored-value facilities / "currency stablecoins" whose aggregate facility credit exceeds A$200 million must register with APRA and comply with APRA prudential standards (registration, not full ADI/bank licensing).
1.2 Discretionary Designation
These jurisdictions empower a designated authority to assess systemic importance case-by-case without fixed quantitative thresholds.
United Kingdom uses a recognition-based approach. HM Treasury recognises a stablecoin issuer as systemically important based on whether the payment system is used widely in payments or whether its failure or disruption could threaten the stability of, or confidence in, the UK financial system. Once recognised, the issuer falls under Bank of England regulation. The UK regime is largely prospective: the full regime commences 25 October 2027. As of mid-2026 the BoE has been recalibrating its proposals -- the proposed requirement to hold 40% of backing assets unremunerated at the Bank of England is being lowered, and the controversial per-individual holding limits are being abandoned in favour of aggregate issuance caps (May 2026). Capital is set as the higher of six months' operating expenses or the recovery/wind-down cost.
Singapore empowers MAS to designate a systemically important stablecoin arrangement as a "Designated Payment System" under the Payment Services Act, attracting enhanced MAS supervision and transaction-finality protections. No quantitative threshold is published, and MAS has indicated that no stablecoin arrangement currently qualifies as systemic in Singapore, but the legal authority exists. Singapore's dedicated Single-Currency Stablecoin (SCS) framework (100% reserves, par redemption, capital, custody) is layered on the PSA, with formal legislative codification still pending as of mid-2026.
United Arab Emirates does not operate a single named systemic-designation regime, but the CBUAE retains discretion to impose higher aggregate capital based on the scale and complexity of an issuer under the Payment Token Services Regulation. A small-issuer exemption applies where reserves are at or below AED 500,000 and there are fewer than 100 holders. This is a scale-sensitive prudential lever rather than a formal systemic tier.
1.3 International Frameworks (Non-Binding)
Financial Stability Board -- The FSB's July 2023 High-level Recommendations (P170723-3) do not set fixed thresholds but identify potential elements for determining whether a stablecoin qualifies as a "global stablecoin arrangement" (GSC). Annex 3 lists: number and type of users, number and value of transactions, size of reserve assets, value of stablecoins in circulation, market share in cross-border payments, number of jurisdictions with users, interconnectedness with financial institutions, interconnectedness with the wider crypto-asset ecosystem, and integration with digital platforms. The October 2025 Thematic Peer Review found "significant gaps and inconsistencies" in implementation, noting that "few jurisdictions have finalised their regulatory frameworks for the global stablecoin recommendations."
BIS/CPMI-IOSCO -- The July 2022 final guidance (d206) on applying the Principles for Financial Market Infrastructures (PFMI) to stablecoin arrangements identifies four overarching considerations for systemic importance: (I) size (number of users, value and volume of transactions, stablecoins in circulation); (II) nature and risk profile (type of users, type/criticality of transactions, denomination); (III) interconnectedness and interdependencies (with other systemically important FMIs, institutions, the real economy); and (IV) substitutability (availability of alternative payment means). No stablecoin has yet been formally designated as a systemically important payment system under this framework.
Basel Committee -- The d545 standard (effective 1 January 2025) operates a different form of designation: stablecoins that meet four classification conditions are classified as Group 1b (favourable capital treatment for bank exposures), while those failing any condition are Group 2b (1,250% risk weight, equivalent to a dollar-for-dollar capital charge). This is not a systemic designation per se, but it determines the degree to which banks can integrate stablecoins into their balance sheets.
1.4 No Formal Framework
The majority of jurisdictions -- including Japan, Brazil, Canada, South Korea, Switzerland, India, South Africa, Bahrain, Nigeria, Turkey, Hong Kong, and Bermuda -- do not have a formal systemic risk designation mechanism specific to stablecoins, though several apply scale-sensitive supervisory levers.
Japan's Payment Services Act applies uniform requirements across all Electronic Payment Instrument (EPI) issuers regardless of size; it tiers obligations by issuer type (bank / fund-transfer service provider / trust) and by fund-transfer transaction size (Type I >JPY 1m, Type II ≤JPY 1m, Type III ≤JPY 50,000) rather than by systemic importance. The PSA Amendment Act 2025 takes effect 1 June 2026, introducing the revised trust-issuer reserve rules (up to 50% in ≤3-month JGBs/US Treasuries). Hong Kong administers the Stablecoins Ordinance (Cap. 656) -- passed 21 May 2025, effective 1 August 2025, with the first two issuer licences (Anchorpoint FRS01 and HSBC FRS02) granted 10 April 2026 -- under a single uniform standard (HK$25 million minimum paid-up capital, 100% reserve backing) with no separate systemic tier; the HKMA states overall licence numbers will remain very limited. Brazil integrates stablecoins through an FX classification rather than a systemic tier, imposing per-transaction caps (USD 500,000 for banks/authorised FIs; USD 100,000 for non-bank SPSAVs) and, via Resolution 561/2026, banning virtual-asset settlement of the offshore leg of regulated eFX cross-border payments (effective 1 October 2026). Canada's federal Stablecoin Act (Division 45 of Bill C-15) received Royal Assent on 26 March 2026 -- it is now law but not yet in force (the in-force date will be set by Order in Council; the framework is anticipated in 2027), and it relies on a National Security Review power rather than a systemic-size tier. South Korea's Digital Asset Basic Act (DABA) remains a pending bill -- introduced June 2025 and re-proposed April 2026, not enacted -- so no systemic-designation regime exists there yet. Switzerland regulates via existing banking/DLT/AML law with no bespoke stablecoin systemic regime. South Africa has no issuer-specific systemic tier (though the SARB classified crypto/stablecoins as a material financial-stability risk in November 2025, and the Prudential Authority is drafting a BCBS-aligned standard for bank crypto-asset exposures). Bahrain, Nigeria, Turkey, Bermuda, and India likewise have no systemic-designation regime specific to stablecoins.

3. What Works / What Doesn't
3.1 What Works
MiCA's quantitative threshold model provides legal certainty. By specifying exact numerical criteria (more than 10 million holders, EUR 5 billion outstanding/reserves, 2.5 million daily transactions, EUR 500 million daily value), MiCA eliminates ambiguity about when enhanced requirements apply. Issuers can model their compliance trajectory. Supervisors have clear triggers for action. The requirement that three of six criteria be met (rather than any single criterion) reduces the risk of premature designation based on a single anomalous metric.
The UK's dual-regulator model creates institutional depth. Separating day-to-day conduct supervision (FCA) from systemic risk oversight (Bank of England) ensures that the entity responsible for financial stability has direct supervisory authority over systemic stablecoins. The BoE's proposed requirement that a substantial share of backing assets be held as unremunerated deposits at the central bank (originally 40%, now being lowered) provides a direct monetary policy transmission channel and ensures the supervisor has real-time visibility into reserve adequacy.
The US $10 billion state-to-federal escalation creates proportionate oversight. Smaller issuers operate under lighter-touch state supervision (where the state regime has been certified "substantially similar" by the SCRC), while larger issuers graduate to federal prudential oversight, with a further audited-financials obligation above $50 billion. The 360-day transition window and 5-day OCC notification obligation provide reasonable adjustment time. The arrangement preserves flexibility for state regulators with demonstrated capacity, while the implementing NPRMs (OCC, FDIC, FinCEN/OFAC) advancing through 2026 are filling in the prudential detail.
FSB's multi-factor assessment captures complexity. The Annex 3 criteria cover dimensions that fixed thresholds miss: interconnectedness with traditional finance, integration with digital platforms (e.g., social networks), cross-border usage patterns, and substitutability. These qualitative factors are essential for identifying systemic risk in stablecoins that may not have the largest market capitalisation but are deeply embedded in critical infrastructure.
CPMI-IOSCO's functional approach bypasses classification debates. By determining that the "transfer function" of a stablecoin arrangement is an FMI function, the PFMI guidance sidesteps the question of whether stablecoins are securities, deposits, or payment instruments. This allows existing, well-tested FMI standards to apply directly to systemically important stablecoin arrangements.
3.2 What Doesn't Work
No stablecoin has been formally designated as systemically important anywhere. Despite USDT processing over $514 billion in adjusted transaction volume in February 2026 alone, and despite USDC processing approximately $1.26 trillion in the same month, no jurisdiction has formally designated any stablecoin issuer as systemically important under either the PFMI framework or national equivalents. This means the most robust layer of systemic risk regulation (PFMI-level standards, central bank direct supervision, resolution planning) remains entirely prospective.
The UK's per-holder limits proved counterproductive enough to be abandoned. The Bank of England's originally proposed limits per individual and per business for systemic stablecoins risked constraining legitimate adoption: if a stablecoin is designated systemic precisely because it is widely used, capping individual holdings may fragment the market across multiple issuers or push users toward unregulated alternatives. By May 2026 the BoE moved to abandon individual holding limits in favour of aggregate issuance caps -- a tacit acknowledgement that no other major jurisdiction imposes per-holder limits.
MiCA's non-euro issuance caps create monetary sovereignty friction. Article 58's daily transaction caps of EUR 200 million or 1 million transactions for non-euro-denominated EMTs represent a tension between monetary sovereignty and market functionality. Given that USDT and USDC together process hundreds of billions of dollars daily, any non-euro stablecoin achieving meaningful EU adoption would breach these thresholds rapidly, forcing issuance cessation and a compliance plan. The practical effect is a de facto soft ban on large-scale non-euro stablecoin usage for payments in the EU.
Recovery and resolution planning remains a critical gap globally. The FSB's October 2025 Thematic Peer Review flagged that "critical gaps include insufficient requirements for robust risk management practices, capital buffers, and recovery and resolution planning." Among major jurisdictions, only the EU (for ARTs under MiCA) and the FSB (Recommendation 7) have explicit, finalised recovery and resolution requirements. The GENIUS Act has no explicit statutory recovery/resolution mandate (the OCC and FDIC NPRMs may address it, but final rules are pending), and the UK BoE framework, Singapore SCS framework, and Hong Kong Stablecoins Ordinance either lack specific recovery/resolution mandates or have not yet finalised them.
Discretionary designation creates uncertainty. The UK, Singapore, and UAE models, which rely on ministerial or regulatory discretion rather than fixed thresholds, create uncertainty for issuers. A stablecoin issuer cannot predict with confidence whether it will be designated, making it difficult to plan compliance investments. The UK model is further complicated by the fact that HMT (a political body) makes the recognition decision, while the BoE (an independent regulator) sets and enforces the requirements.
4. The Current Systemic Landscape: Would Major Stablecoins Trigger Designation?
4.1 Tether (USDT) and USAT
USDT holds approximately $184 billion in market capitalisation. The global USDT token is issued from El Salvador and is not authorised under MiCA, the GENIUS Act, or the UK regulatory framework. In January 2026, Tether launched USAT, a separate GENIUS-compliant US stablecoin issued via Anchorage Digital Bank, coexisting with global USDT.
EU MiCA significance assessment: USDT would almost certainly meet the EUR 5 billion outstanding value threshold, the 2.5 million daily transaction threshold, and the EUR 500 million daily transaction value threshold -- satisfying at least three of six criteria. However, because Tether has not obtained MiCA authorisation and USDT has been delisted from major EU-accessible platforms, the significance assessment is moot. Global USDT is effectively excluded from the EU market.
US GENIUS Act: Global USDT's reserve composition (which includes bitcoin, gold, and secured loans) is not compliant with the Act's permitted reserve assets (limited to US dollars, insured deposits, T-bills at 93 days or less, repos/reverse repos backed by Treasuries, government MMFs, and central bank reserves). Tether's response was to launch the separately structured, GENIUS-compliant USAT for US persons rather than retrofit global USDT. At $184 billion outstanding, global USDT would far exceed the $10 billion federal-transition threshold, the $25 billion large-issuer threshold, and the $50 billion audit threshold.
UK: Would be assessed for systemic recognition by HMT only if it sought UK authorisation, which it has not done.
4.2 Circle (USDC)
As of 2026, USDC held approximately $79 billion in market capitalisation. USDC processed approximately $1.26 trillion in adjusted transaction volume in February 2026 alone, surpassing USDT in this metric for the first time since 2019. Circle obtained an Electronic Money Institution licence from France's ACPR on 1 July 2024 (the first global stablecoin issuer to achieve MiCA compliance) and received a conditional national trust bank charter from the OCC in December 2025 (one of five conditional charters granted alongside Ripple, BitGo, Fidelity Digital Assets, and Paxos).
EU MiCA significance assessment: USDC would likely meet the EUR 5 billion outstanding value threshold and potentially the daily transaction value threshold. Whether it meets three of six criteria depends on holder counts and transaction volumes within the EU specifically (not globally). The EBA has not yet made a significance determination for USDC. If designated significant as a non-euro EMT, USDC would face the Article 58 issuance caps.
US GENIUS Act: Circle's reserve composition (primarily the Circle Reserve Fund, an SEC-registered government money market fund containing cash, short-dated Treasuries, and overnight Treasury repos) is already compliant with GENIUS Act permitted reserve assets. At $79 billion, USDC would exceed the $10 billion federal-transition threshold, the $25 billion large-issuer threshold, and the $50 billion audit threshold.
4.3 Stress Event Analysis
Terra/LUNA (May 2022): The collapse of the TerraUST algorithmic stablecoin demonstrated that a stablecoin need not be "systemic" in the traditional financial system sense to cause devastating cascading failures within the crypto ecosystem. TerraUST had approximately $18 billion in market capitalisation before collapse -- well below MiCA's EUR 5 billion significance threshold. The collapse erased over $60 billion in combined value and triggered the bankruptcy of Three Arrows Capital, which in turn caused the failures of Voyager Digital, Celsius Network, Genesis Asia Pacific, BlockFi, and contributed to the collapse of FTX. The aftermath included a $4.47 billion SEC settlement against Terraform Labs (approved June 2024). This case demonstrates that systemic risk thresholds calibrated to traditional financial metrics may fail to capture crypto-native contagion channels, particularly through DeFi lending protocols and leveraged crypto fund exposures.
USDC/Silicon Valley Bank (March 2023): Circle disclosed $3.3 billion in exposure to SVB (approximately 8% of USDC reserves). USDC depegged to approximately $0.87 within hours. The depeg cascaded to other stablecoins -- DAI, USDD, and USDP all experienced secondary depegging. USDC recovered its peg on Monday 13 March after the US government announced a backstop for SVB depositors. This event demonstrated that stablecoin systemic risk is bidirectional: a traditional banking failure destabilised a stablecoin, and the stablecoin depeg in turn amplified market stress. A Federal Reserve FEDS Note published in December 2025 analysed the episode as an illustration of the "shadow of bank runs" affecting stablecoins.
5. Recommended Framework: Tiered Systemic Risk Designation
Drawing on precedents from all jurisdictions analysed, a regulator designing a systemic risk designation framework for stablecoins should consider the following tiered model.
Tier 1: Standard Stablecoin Issuer
Trigger: Below all Tier 2 thresholds.
Requirements:
- Licensing and authorisation from competent authority (precedent: all major jurisdictions)
- 1:1 reserve backing in high-quality liquid assets (precedent: GENIUS Act, MiCA, Singapore SCS, Hong Kong Stablecoins Ordinance, UAE PTSR)
- Par redemption within T+1 or T+2 (precedent: UK FCA next-business-day; NYDFS T+2; US FDIC NPRM two-business-day; MiCA at-any-time; Hong Kong one business day)
- Monthly attestation of reserve adequacy (precedent: GENIUS Act, NYDFS)
- AML/KYC compliance including travel rule (precedent: universal)
- Basic governance requirements and white paper/disclosure (precedent: MiCA, FSB Rec 8)
Supervisor: National competent authority or state-level regulator.
Tier 2: Significant Stablecoin Issuer
Trigger: Meeting at least three of the following six criteria (modelled on MiCA Articles 43/56, calibrated to jurisdiction):
| Criterion | Suggested Threshold | MiCA Precedent |
|---|---|---|
| Number of holders | >10 million | Article 43(1)(a) / 56(1)(a) |
| Outstanding value / market cap | >USD 5 billion equivalent | Article 43(1)(b) / 56(1)(b) |
| Average daily transaction count | >2.5 million | Article 43(1)(c) / 56(1)(c) |
| Average daily transaction value | >USD 500 million equivalent | Article 43(1)(d) / 56(1)(d) |
| Cross-border usage | Significant volume in 3+ jurisdictions | Article 43(1)(e) / 56(1)(e), FSB Annex 3 |
| Financial system interconnectedness | Material linkages to banks, FMIs, or DeFi protocols | Article 43(1)(f) / 56(1)(f), CPMI-IOSCO d206 |
Enhanced Requirements:
- Higher capital: up to 3% of average reserve assets (precedent: MiCA significant ART/EMT)
- Enhanced liquidity: 40% of reserves liquidatable within 1 day, 60% within 5 days; minimum 60% in bank deposits (precedent: MiCA significant token liquidity RTS)
- Enhanced governance: independent risk committee, independent directors, fit-and-proper testing of all senior management (precedent: MiCA Article 34, FSB Rec 4)
- Annual audited financial statements (precedent: GENIUS Act >$50B threshold)
- Recovery and resolution planning (precedent: MiCA Article 46, FSB Rec 7)
- Enhanced reporting frequency (quarterly to prudential authority)
Supervisor: Prudential authority or dedicated supervisory body (not just conduct authority). Precedent: EBA for significant tokens under MiCA; BoE for systemic stablecoins in UK; OCC/Fed for >$10B issuers under GENIUS Act; APRA for >A$200M issuers under Australia's proposed Tranche 1.
Tier 3: Systemically Important Stablecoin Arrangement
Trigger: Designation by the competent authority based on a comprehensive assessment incorporating:
- All Tier 2 quantitative criteria, at elevated levels (e.g., >$50 billion outstanding, >50 million holders)
- Qualitative factors from FSB Annex 3 and CPMI-IOSCO d206: interconnectedness with the broader financial system, substitutability, integration with critical digital infrastructure
- Assessment of cross-border systemic relevance (precedent: FSB "global stablecoin arrangement")
- Evidence that failure or disruption would threaten financial stability
Enhanced Requirements:
- Central bank reserve deposit requirement: a substantial share of reserves held at the central bank (precedent: UK BoE proposal for systemic stablecoins, originally 40%, being recalibrated)
- Full PFMI compliance (all 24 principles as applicable) (precedent: CPMI-IOSCO d206)
- Central bank direct supervision or co-supervision (precedent: BoE for UK systemic stablecoins; EBA for significant ARTs)
- Formal resolution plan approved by resolution authority (precedent: FSB Rec 7, bank resolution frameworks)
- Stress testing requirement (liquidity, operational, cyber) (precedent: FSB Rec 5, CPMI-IOSCO Principle 3)
- Settlement finality regime (precedent: CPMI-IOSCO d206 Principle 8; Singapore Designated Payment System under the PSA)
- Potential aggregate issuance caps or concentration restrictions if monetary sovereignty concerns arise (precedent: UK BoE aggregate issuance caps; MiCA Article 58 non-euro caps; Brazil FX per-transaction caps)
Supervisor: Central bank or equivalent, with cross-border cooperation arrangements (precedent: FSB Rec 3; CPMI-IOSCO Annex on cooperation; BoE for UK; Fed for US).
Transition Mechanism
Drawing on the GENIUS Act model, the framework should include:
- A defined transition period (e.g., 360 days) for issuers crossing into a higher tier
- A notification obligation upon crossing thresholds (precedent: GENIUS Act 5-calendar-day OCC notice)
- A certification or waiver mechanism allowing the supervisor to recognise the quality of an existing state/sub-national regime (precedent: GENIUS Act SCRC "substantially similar" certification)
- Voluntary opt-in to higher tier requirements (precedent: MiCA voluntary significance classification)
6. Decision Matrix for Regulators
The following matrix assists regulators in determining the appropriate systemic risk framework for their jurisdiction, based on current conditions.
Step 1: Assess Domestic Stablecoin Market Maturity
| Condition | Recommendation |
|---|---|
| No significant stablecoin issuance or usage domestically | Adopt baseline licensing framework (Tier 1 only); prepare legal authority for future designation |
| Stablecoin usage growing but no issuer approaching significance thresholds | Implement Tier 1 + Tier 2 framework with clear quantitative triggers |
| One or more stablecoins approaching or exceeding significance thresholds | Implement full three-tier framework with immediate designation process |
| Stablecoins already deeply integrated into payment infrastructure | Designate and apply Tier 3 (PFMI-level) requirements immediately |
Step 2: Choose Designation Model
| Factor | Threshold-Based (MiCA model) | Discretionary (UK model) | Hybrid (GENIUS Act model) |
|---|---|---|---|
| Legal certainty for issuers | High | Low | Medium |
| Flexibility for regulator | Low | High | Medium |
| Speed of designation | Automatic when criteria met | Depends on political/regulatory process | Automatic at size threshold; discretionary for qualitative factors |
| Risk of regulatory capture | Lower (criteria are fixed) | Higher (discretion creates lobbying opportunity) | Medium |
| Suitable for | Developed markets with multiple issuers | Markets with few but large issuers | Markets with state/federal division |
Step 3: Determine Enhanced Requirements
| Requirement | Essential (all frameworks) | Recommended (Tier 2+) | Advanced (Tier 3 only) |
|---|---|---|---|
| 1:1 reserve backing | Yes | Yes | Yes |
| Permitted asset restrictions | Yes | Yes, more restrictive | Yes, most restrictive |
| Capital requirements | Basic (e.g., 2% of reserves) | Enhanced (e.g., 3% of reserves) | Bank-equivalent or higher |
| Liquidity buffers | Basic | Enhanced (40%/60% 1-day/5-day) | Central bank deposit requirement |
| Governance | Fit-and-proper testing | Independent risk committee | Full board independence requirements |
| Reporting | Monthly attestation | Quarterly prudential reporting | Real-time reserve monitoring |
| Recovery planning | Not required | Required | Required and approved by resolution authority |
| Resolution planning | Not required | Recommended | Required |
| Stress testing | Not required | Annual | Semi-annual + ad hoc |
| Cross-border cooperation | Not required | Recommended | Required (supervisory college) |
Step 4: Assess Monetary Sovereignty Implications
| Condition | Recommended Action |
|---|---|
| Foreign-currency stablecoin usage is minimal (<5% of domestic payments) | No issuance caps needed |
| Foreign-currency stablecoin usage is growing (5-20%) | Monitor and prepare legislative authority for caps |
| Foreign-currency stablecoin usage is significant (>20%) | Consider transaction caps (MiCA Article 58 / Brazil FX model) or aggregate issuance caps (UK BoE model) |
| Currency substitution risk is acute | Consider requiring local-currency denomination for systemic stablecoins |
