When Congress signed the GENIUS Act on July 18, 2025, the stablecoin industry celebrated regulatory clarity. What it actually got was one more framework in a world that already had six.
The GENIUS Act is a good law. Its reserve requirements are conservative, its attestation requirements are specific, and its bankruptcy protections are genuine. But it was designed for the American market, and stablecoins do not have a domestic market. USDC circulates on twenty-plus chains across every jurisdiction on earth. The regulatory question is not "what does the GENIUS Act require?" — it is "what do seven different frameworks require simultaneously, and where do they conflict?"
This is the complete map. Not the summary — the practitioner-level detail that a compliance officer, a CPA performing reserve examinations, or an issuer's general counsel needs to operate.
Part I: The United States
The GENIUS Act Framework
The Guiding and Establishing National Innovation for U.S. Stablecoins Act (S.1582) passed the Senate 68-30 on June 17, 2025, the House 308-122 on July 17, and was signed July 18. Implementing regulations from six agencies are due by July 18, 2026, with the framework effective 120 days later — approximately mid-November 2026. If agencies miss the deadline, the framework takes effect no later than January 18, 2027.
Eligible reserve assets are a closed list. Section 4(a)(1)(A) enumerates six categories:
- Physical U.S. coins and Federal Reserve notes
- Demand deposits at FDIC-insured depository institutions
- U.S. Treasury bills, notes, or bonds with remaining maturities of 93 days or less
- Repurchase agreements backed by qualifying Treasury securities with terms no longer than 7 days
- Shares in SEC-registered government money market funds (Rule 2a-7) investing solely in the above
- Other similarly liquid federal government assets approved by the primary regulator
The list is exclusive. Commercial paper, CDs beyond insured deposit limits, longer-duration Treasuries, corporate bonds, non-Treasury repos, foreign sovereign debt, gold, and digital assets are all excluded. This is more conservative than what Tether currently holds — their reserves include gold ($18.8B), Bitcoin ($8B), and secured loans, none of which qualify under the GENIUS Act.
Reserves may not be pledged, rehypothecated, or reused except for margin obligations, custodial services, or redemption liquidity. They must be held in segregated, bankruptcy-remote accounts.
Attestation requirements are the most specific of any jurisdiction. Monthly attestation by a PCAOB-registered public accounting firm. CEO and CFO must personally certify accuracy under 18 U.S.C. Section 1350(c) — the same criminal certification standard as Sarbanes-Oxley Section 906. Issuers exceeding $50 billion in outstanding stablecoins must additionally file annual GAAP financial statements audited under PCAOB standards.
This effectively embeds an external public accounting firm into the issuer's monthly close cycle permanently.
Three licensing paths exist: subsidiary of an insured depository institution, federal-qualified nonbank issuer (OCC-supervised), or state-qualified issuer (state-supervised below $10B). The $10 billion threshold is a hard gate: a state-licensed issuer crossing $10B must notify the OCC within five business days and transition to federal oversight within 360 days, or cease issuing.
Redemption must be at par, with the OCC's proposed implementing rule adding a three-tier liquidity structure: 10% redeemable same business day, 30% within five business days, 60% in standard qualifying assets.
Yield is prohibited. Section 4(a)(11) bars issuers from paying interest or yield in any form — cash, tokens, or other consideration — solely for holding stablecoins. The OCC's proposed rule extends this to affiliates and third parties, closing the "rewards program" loophole. This is a deliberate policy choice to prevent stablecoins from competing with bank deposits.
Bankruptcy priority looks strong on paper but has structural weaknesses. Reserve assets are declared not property of the bankruptcy estate, with an expedited 14-day distribution procedure. However, Georgetown Law's Adam Levitin has demonstrated that holders actually rank fifth in practical priority, behind repo lenders, DIP lenders, professional fee carve-outs, and set-off claims from depositaries. The statutory priority addresses unsecured claims under Section 726, but secured claims are paid first.
The State Money Transmitter Overlay
The GENIUS Act preempts state money transmitter licensing only for permitted payment stablecoin issuers — and only for their stablecoin issuance activity. Exchanges, custodians, and intermediaries that transmit stablecoins but are not issuers still need state MTLs in up to 49 jurisdictions (Montana is the sole state with no requirement).
State bonding requirements range from $25,000 to several million dollars depending on jurisdiction and volume. These stack on top of federal reserve requirements. Both federal and state regulators retain examination authority, creating the possibility of simultaneous examinations with different scopes and potentially conflicting conclusions.
Four states have adopted the Money Transmission Modernization Act (MTMA) as of August 2026: Mississippi, Colorado, Nebraska, and Virginia. Wyoming offers a Special Purpose Depository Institution charter with a $5 million capital requirement. New York operates its own regime through NYDFS (see below).
NYDFS: The Template
NYDFS issued stablecoin-specific guidance on June 8, 2022 — three years before the GENIUS Act. The requirements were the template Congress built upon: full 1:1 backing in high-quality liquid assets (Treasuries, insured deposits, government MMFs), segregation from proprietary assets, monthly independent CPA attestation, and clear redemption policies.
The GENIUS Act is stricter on one dimension: it requires PCAOB-registered firms and CEO/CFO criminal certification, which NYDFS does not. NYDFS is stricter on another: it has actively enforced compliance failures, fining Paxos $26.5 million in August 2025 for BSA/AML deficiencies tied to the Binance/BUSD relationship.
The IRS Problem
The GENIUS Act treats stablecoins as payment instruments. The IRS treats them as property under Notice 2014-21. No provision in the GENIUS Act directed the IRS to update its classification.
The result: every stablecoin transaction — every payment, every transfer, every conversion — is a taxable event requiring cost basis tracking and gain/loss calculation, even when the gain is zero. A business paying a vendor in USDC must calculate capital gain/loss on each transaction. A freelancer receiving USDC creates two taxable events: receipt as income and conversion as property disposition.
The PARITY Act (introduced May 19, 2026) proposes a peg stability safe harbor for GENIUS Act-compliant stablecoins acquired within 1% of par, but it has not passed. Until it does, every stablecoin transaction remains a reportable property disposition. The compliance cost is disproportionate to the tax at stake, and no practitioner can advise a client otherwise.
Part II: The European Union — MiCA
The Markets in Crypto-Assets Regulation took full effect with the July 1, 2026 transitional deadline. Non-compliant issuers lost their grandfathering.
MiCA distinguishes between E-Money Tokens (EMTs) — stablecoins pegged to a single fiat currency — and Asset-Referenced Tokens (ARTs) — stablecoins referencing multiple assets or commodities. As of Q1 2026, 19 EMT issuers are authorized across 11 EU countries, issuing 29 tokens. Zero ARTs have been authorized.
Where MiCA diverges from the GENIUS Act:
Reserve composition: MiCA requires that at least 60% of reserves for "significant" EMTs be held in credit institution deposits across at least six banks with no more than 10% concentration per bank. The GENIUS Act has no such diversification requirement — 100% in Treasuries is acceptable. An issuer compliant with one framework may not be compliant with the other using the same reserve portfolio.
Interest prohibition: MiCA prohibits stablecoin issuers from paying interest or yield to holders. The GENIUS Act has the same prohibition. This is one of the few points of alignment.
Attestation: MiCA requires reserve transparency but does not specify PCAOB-registration or monthly AT-C 205 examinations. The assurance framework is less prescriptive than the GENIUS Act's requirements.
Whitepaper: MiCA requires a published crypto-asset white paper with standardized disclosures — a requirement with no GENIUS Act equivalent.
The practical effect: a global issuer must maintain structurally distinct reserve portfolios and governance frameworks for U.S. and EU operations. Circle has already disclosed that its EU operations (through Circle Mint Europe SAS, licensed by the French ACPR) require separate reserve management from its U.S. operations.
Part III: Asia-Pacific
Singapore — MAS Single-Currency Stablecoin Framework
The Monetary Authority of Singapore finalized its SCS framework in 2023, requiring a Major Payment Institution license, 1:1 reserves in high-quality assets, and par-value redemption. StraitsX (XSGD, XUSD) is the first issuer acknowledged as substantively SCS-compliant. Paxos Digital Singapore operates USDG under MAS oversight with reserves managed by DBS Bank.
Singapore's approach is principles-based where the GENIUS Act is rules-based. MAS specifies reserve quality without enumerating a closed list of eligible assets. Attestation is required but the framework defers to ISCA standards rather than mandating PCAOB registration.
Japan — Payment Services Act
Japan's amendments to the Payment Services Act created a licensing path for stablecoin issuers through Type II funds transfer licenses or trust bank structures. JPYC Inc. became the first FSA-approved yen stablecoin issuer in October 2025. Foreign trust-type stablecoins became eligible as "electronic payment instruments" from June 1, 2026.
Japan's framework is notable for its conservative approach to foreign stablecoins — USDC and USDT were not readily available on Japanese exchanges for years. The June 2026 opening represents a significant policy shift, though with strict guardrails.
Hong Kong — HKMA Stablecoins Ordinance
The HKMA licensed its first two stablecoin issuers on April 10, 2026: Anchorpoint Financial (a Standard Chartered / HKT / Animoca Brands joint venture) and HSBC. Both are preparing HKD-pegged stablecoins for launch in the second half of 2026.
Hong Kong's framework requires 1:1 reserves in high-quality assets under HKMA supervision — functionally similar to the GENIUS Act but with Hong Kong-specific banking relationships.
Part IV: Middle East and Offshore
UAE — The Four-Regulator Problem
The UAE has four distinct regulatory authorities governing stablecoins, each with different scope:
- CBUAE: Regulates AED-pegged stablecoins. Licensed Zand Bank for an AED stablecoin.
- VARA (Dubai mainland): Regulates non-AED stablecoins as "Fiat-Referenced Virtual Assets."
- ADGM (Abu Dhabi): Licensed Paxos Issuance MENA for USDL (now wound down) and Circle.
- DFSA (DIFC): Recognizes specific tokens for trading/custody but does not license issuers.
An issuer operating in Dubai must navigate at least two of these frameworks depending on the token's peg currency and the legal jurisdiction of their entity.
Bermuda — BMA DABA
Bermuda's Digital Asset Business Act provides a DABA licensing path. Mountain Protocol operated under a BMA Class M license for USDM before winding down in August 2025. Bermuda positions itself as a stablecoin-friendly jurisdiction but the Mountain Protocol experience demonstrates the risks of small-jurisdiction licensing for stablecoin issuers.
Part V: Where the Frameworks Conflict
A global issuer — say, Circle operating USDC across the U.S., EU, and Singapore — faces these specific contradictions:
Reserve composition: The GENIUS Act allows 100% Treasuries. MiCA requires 60% in diversified bank deposits. Singapore's MAS is principles-based. Circle cannot hold a single reserve portfolio that satisfies all three frameworks simultaneously. It maintains structurally separate reserve arrangements per jurisdiction.
Attestation frequency and standard: The GENIUS Act requires monthly PCAOB-registered examination. MiCA requires transparency but is less specific about engagement type. Singapore defers to ISCA standards. A monthly AT-C 205 examination that satisfies the GENIUS Act does not automatically satisfy MiCA's transparency requirements or Singapore's ISCA-based attestation expectations.
Interest prohibition: Both the GENIUS Act and MiCA prohibit yield payments to holders. Singapore does not explicitly prohibit yield. This creates an asymmetry where a yield-bearing stablecoin could legally exist under MAS oversight but would violate both U.S. and EU law.
Bankruptcy treatment: The GENIUS Act provides specific (if imperfect) bankruptcy priority for holders. MiCA requires reserve segregation and holder protection but through EU insolvency law, which varies by member state. Singapore follows its own insolvency framework. A holder of USDC in three jurisdictions has three different recovery profiles in an issuer insolvency.
Tax treatment: The U.S. treats stablecoins as property (capital gains on every transaction). The EU generally treats stablecoins as e-money (no capital gains on euro-pegged stablecoins used as payment). Singapore has no capital gains tax. A cross-border payment in USDC triggers different tax obligations depending on the sender's and receiver's jurisdictions.
Part VI: The Attestation Standards Gap
The professional standards governing stablecoin assurance are not harmonized across jurisdictions.
In the U.S., the GENIUS Act requires examination-level attestation — the highest assurance tier under AICPA AT-C 205. The practitioner obtains sufficient evidence to express an affirmative opinion: "In our opinion, management's assertion is fairly stated, in all material respects."
Under ISAE 3000 (Revised), used by BDO Italia for Tether, reasonable assurance engagements produce a structurally similar conclusion but under a different framework. The assurance levels are broadly equivalent, but the engagement procedures, documentation requirements, and quality control expectations differ.
Under ISCA standards (Singapore), the attestation framework follows Singapore-specific professional pronouncements that may not map directly to either AT-C or ISAE 3000.
The result: a reader comparing a Deloitte AT-C 205 examination opinion on Circle's reserves to a BDO Italia ISAE 3000 report on Tether's reserves is comparing conclusions produced under different frameworks, by firms subject to different quality control regimes, with different supervisory consequences for errors.
The Reserve Attestation Registry tracks this distinction for every record. The engagement type, standard, and practitioner are facts. Whether the assurance levels are equivalent is interpretation. The facts are in the registry. The interpretation is in this article.
Part VII: What This Map Means
Three conclusions emerge from the complete picture:
1. No single framework governs stablecoins. The market operates under at least seven live regulatory regimes, with more developing. A global issuer's compliance burden is the union of all applicable frameworks, not the intersection. The strictest requirement in any applicable jurisdiction becomes the effective floor.
2. The attestation standard is the differentiator. The GENIUS Act's requirement of monthly PCAOB-registered examination with criminal CEO/CFO certification is the most demanding assurance standard for stablecoin reserves in any jurisdiction. Issuers who already meet this bar (Circle, Paxos, Ripple, Gemini) have a structural advantage. Issuers who do not (Tether, under quarterly ISAE 3000 AUP by a non-PCAOB firm) face a compliance gap that is now statutory.
3. The tax question is unresolved everywhere. The U.S. property classification, the EU's e-money treatment, and Singapore's no-capital-gains approach represent three fundamentally different philosophies about what a stablecoin is for tax purposes. Until these are harmonized — or until the PARITY Act or equivalent legislation passes in the U.S. — cross-border stablecoin payments create unpredictable tax obligations.
The map is drawn. The jurisdictions are live. The conflicts are real. And the compliance officer's job just got a lot harder.
