GENIUS Act Final Rules: What Stablecoin Regulation Means for Offshore Fund Managers
Stablecoins are the settlement layer of virtually every digital asset fund: the leg of the arbitrage, the collateral on the derivatives venue, the parking place between positions. That is why the GENIUS Act, enacted on 18 July 2025 as the first comprehensive US federal framework for payment stablecoins, reaches well beyond issuers. Federal rulemaking is now finalising: the OCC proposed implementing rules in March 2026, the FDIC and Treasury followed with proposals in April 2026, FinCEN and OFAC issued their illicit-finance proposals in the same window, and the agencies face the Act's one-year rulemaking milestone in mid-July 2026, with full effectiveness approaching by January 2027. An offshore fund manager is not a stablecoin issuer, but the fund's treasury policy, custody arrangements and yield strategies will all feel the new regime, and the time to adjust them is before effectiveness, not after.
"Most managers still treat stablecoin selection as a trading preference. Under the GENIUS Act it becomes a compliance decision: which coins are issued by permitted issuers, which foreign issuers will qualify, and where the fund's yield actually comes from once issuers themselves cannot pay it. Funds that write this into treasury policy now will find the transition administrative; funds that ignore it will find it disruptive."David Lloyd, Chief Executive Officer at CV5 Capital
Why This Matters for Funds and Managers
The GENIUS Act establishes a federal category of permitted payment stablecoin issuers, subjects them to one-to-one reserve requirements in high-quality liquid assets with regular disclosure, restricts who may lawfully issue payment stablecoins into the US market, and, most consequentially for fund strategies, prohibits payment stablecoin issuers from paying yield or interest to holders. Implementation has moved quickly by regulatory standards. According to the OCC, its proposed regulations to implement the Act were published in March 2026; the US Treasury announced its proposed rule addressing illicit-finance requirements in April 2026, alongside FDIC proposals for the institutions it supervises. With comment periods closed in early June 2026, the agencies are working towards the statutory milestone of 18 July 2026, one year after enactment, with the framework's full effectiveness following by January 2027.
For an offshore manager the significance is second-order but real. The composition of the stablecoin market is likely to consolidate around compliant issuers as effectiveness approaches, with implications for liquidity, venue support and counterparty acceptance of non-compliant coins. US-facing service providers, custodians, prime brokers and exchanges can be expected to restrict support for stablecoins that do not fit the framework. And allocators, particularly US institutions, will start asking in due diligence how the fund's treasury policy addresses the new regime, in the same way they already probe custody and valuation. This sits within the broader reconstruction of US digital asset regulation we examine in our review of US market structure and Cayman funds.
The Common Misunderstanding
The reflex reading among offshore managers is that a US issuer statute cannot matter to a Cayman fund. That confuses who is regulated with who is affected. It is true that a Cayman fund holding stablecoins is not an issuer and does not itself need a US licence to hold or use them. But the Act's architecture reaches the fund through its holdings and its counterparties: foreign issuers face conditions for lawfully offering into the US market, US intermediaries will be constrained in the coins they support, and a coin that loses its US distribution can lose liquidity globally. A fund whose operations assume frictionless access to a particular stablecoin is exposed to that coin's regulatory position whether or not the fund is in scope itself.
The second misunderstanding concerns yield. The Act prohibits permitted payment stablecoin issuers from paying yield to holders; it does not prohibit funds from earning returns on or around stablecoins. What it does is relocate the yield: away from the coin itself and into third-party constructs, lending markets, tokenised money market funds, on-chain treasury products and basis strategies, each with a distinct risk, custody and accounting profile. That distinction is the foundation of any credible stablecoin strategy, and it is where the design work we describe in how to launch a stablecoin yield fund begins. The accounting consequences of DeFi-sourced yield are a discipline of their own, covered in our guide to DeFi fund accounting.
The Practical Reality: Mapping the Act to Fund Operations
The table below translates the framework's main elements into their practical implications for an offshore digital asset fund, on the basis of the Act and the agencies' proposed rules; details may shift as final rules are adopted.
| GENIUS Act element | Practical implication for offshore fund managers |
|---|---|
| Permitted issuer framework | Stablecoin selection becomes a compliance judgement. Treasury policy should define which coins the fund may hold by reference to issuer status, not merely liquidity. |
| One-to-one reserves and disclosure | Reserve composition and attestation quality become diligence inputs; compliant coins are easier to defend to allocators and auditors as cash-equivalent operational balances. |
| Yield prohibition on issuers | Holding a compliant coin will not itself generate return. Yield must be sourced from third-party structures, each requiring its own risk, custody and valuation treatment. |
| Foreign issuer provisions | Non-US issuers face conditions for US market access; coins that fail to qualify may see US venue and intermediary support withdrawn, with knock-on liquidity effects offshore. |
| FinCEN and OFAC rules | AML and sanctions expectations around stablecoin flows tighten; funds should expect more granular questions from banks, brokers and administrators about stablecoin counterparties. |
| Timeline to effectiveness | Final rules were being completed around mid-July 2026, with full effectiveness approaching by January 2027; the transition window for treasury and documentation changes is now. |
CV5 Insight: The GENIUS Act quietly upgrades compliant stablecoins into institutional plumbing, and the funds that benefit will be those whose offering documents, treasury policies and NAV processes already treat them that way.
Key Considerations Before the Rules Take Full Effect
A stablecoin readiness checklist
- Write a stablecoin treasury policy: Define eligible coins by issuer status, reserve quality and attestation cadence, with board-level approval and periodic review.
- Map current holdings: Identify exposure to coins whose issuers may not qualify under the final rules, and plan orderly substitution rather than forced migration.
- Re-underwrite yield sources: Document where every unit of stablecoin-linked return originates, issuer, lending market, tokenised fund or basis trade, and its custody and valuation treatment, consistent with the standards in our guide to yield strategies in funds.
- Check disclosure documents: Offering memoranda describing stablecoin use should reflect the new regime and avoid implying yield is a property of the coin itself.
- Anticipate counterparty behaviour: Ask custodians, brokers and venues how they will treat non-compliant coins as effectiveness approaches.
- Coordinate across regimes: US stablecoin rules land alongside the EU's MiCA e-money token framework; managers with EU touchpoints should read the two together, as we discuss in our analysis of the end of MiCA's transitional period.
Managers building products around compliant stablecoins and tokenised cash have a structural question too: where does such a strategy best sit? The interaction between stablecoins, tokenised deposits and a CIMA-regulated fund stack is one we examine in tokenised deposits, stablecoins and the CIMA fund stack.
How the CV5 Platform Model Helps
Stablecoin Strategies on a Regulated Cayman Chassis
CV5 Capital is a Cayman Islands-based, CIMA-registered fund platform. Through CV5 Digital SPC, managers can run stablecoin and digital asset strategies inside an institutional structure built for exactly this kind of regulatory transition:
- Treasury and custody governance: Wallet governance, custody coordination and administrator visibility that make a stablecoin treasury policy operational rather than aspirational.
- Documentation discipline: Offering documents and valuation policies drafted to describe stablecoin use and yield sources accurately as the US rules take effect.
- Segregated portfolio structure: A stablecoin yield strategy can sit in its own segregated portfolio, keeping its risk profile distinct from other strategies on the platform.
- Cross-regime awareness: A Cayman structure designed to sit coherently alongside US, EU and Asian regulatory frameworks as they evolve.
CV5 does not make investment decisions for third-party strategies and is not a law firm, administrator, auditor or investment adviser. Managers retain their strategy, branding and investment discretion, supported by the regulated infrastructure described at the CV5 digital asset fund platform.
Risks and Caveats
The rulemaking described here was still completing as at early July 2026: proposed rules may change materially before adoption, agencies can miss statutory deadlines, and the treatment of specific issuers, foreign regimes and products will only be settled as final rules and supervisory practice emerge. Nothing above is a prediction of which stablecoins will qualify, and holding any stablecoin carries issuer, reserve, depeg, smart contract and counterparty risks that regulation reduces but does not remove. Yield-bearing structures around stablecoins carry their own market and credit risks. Managers should take US regulatory advice on any strategy with US investors, counterparties or distribution.
Key Takeaways
- The GENIUS Act, enacted 18 July 2025, created the first US federal framework for payment stablecoins; implementing rules from the OCC, FDIC, Treasury, FinCEN and OFAC were finalising around mid-July 2026, with full effectiveness approaching by January 2027.
- Offshore funds are not issuers, but treasury policy, custody, counterparty support and coin liquidity are all affected through the fund's holdings and intermediaries.
- Issuers cannot pay yield to holders, so stablecoin-linked returns must come from third-party structures with distinct risk, custody and accounting profiles.
- Foreign issuer provisions mean a coin's US regulatory position can drive its global liquidity; treasury policies should define eligible coins by issuer status.
- The practical transition window is now: policies, offering documents and counterparty arrangements are easier to adjust before effectiveness than after.

Schedule a ConsultationFrequently Asked Questions
Does the GENIUS Act apply to a Cayman fund holding stablecoins?
Not directly. The Act regulates payment stablecoin issuers and those offering stablecoins into the US market, not offshore funds that hold them. The practical effects reach the fund indirectly, through which coins remain widely supported, how US counterparties behave and what allocators expect treasury policy to say.
Can a fund still earn yield on stablecoins after the GENIUS Act?
Generally yes, but not from the issuer. The Act prohibits permitted payment stablecoin issuers from paying yield to holders, so returns must come from third-party sources such as lending markets, tokenised money market funds or basis strategies, each of which carries its own risk, custody, valuation and accounting treatment that should be documented.
When do the GENIUS Act rules take effect?
The Act was enacted on 18 July 2025, agencies published proposed rules between March and April 2026 and were finalising them around the statute's one-year milestone in mid-July 2026, with the framework's full effectiveness approaching by January 2027. Timing details depend on the final rules and should be monitored.
What should an offshore manager do now?
Adopt a board-approved stablecoin treasury policy defining eligible coins by issuer status; map current holdings against the likely final framework; document all yield sources; update offering documents where they describe stablecoin use; and ask custodians and venues how they will treat non-compliant coins. Structure-specific questions should go to US counsel.
