The banking industry's most influential policy research arm has drawn a hard line on state stablecoin regulation.
The Bank Policy Institute submitted a letter to the Treasury Department this week arguing that state-level oversight of payment stablecoins must match or exceed the federal regulatory framework under the GENIUS Act in every material respect, warning that any meaningful gap between state and federal standards will incentivize stablecoin issuers to seek licensure in the most permissive state and trigger the same regulatory arbitrage dynamic that contributed to the banking and thrift crisis of the 1980s and early 1990s.
The letter responds directly to a Treasury proposal laying the groundwork for determining when a state-level stablecoin regulatory regime is "substantially similar" to the federal framework, a determination that will govern which of the GENIUS Act's smaller issuers can opt for state rather than federal oversight.
As covered in our GENIUS Act community bank loophole analysis, the state opt-in provision for issuers with $10 billion or less in outstanding stablecoin supply is one of the most consequential structural decisions embedded in the legislation, and the BPI letter represents the banking industry's formal position on how Treasury should interpret it.
Key Takeaways
- BPI urges Treasury to set the "substantially similar" threshold so that state stablecoin regimes have no meaningful differences in reserves, capital, liquidity, and no-yield rules versus the federal framework.
- BPI explicitly warns against regulatory arbitrage, drawing a cautionary parallel to state-chartered bank regulatory competition that contributed to the 1980s banking and thrift crisis.
- The GENIUS Act allows stablecoin issuers with $10 billion or less in outstanding supply to opt for state regulation, making Treasury's "substantially similar" determination a high-stakes threshold for the entire stablecoin market.

What BPI Told Treasury and Why It Matters
The BPI letter argues that minimizing differences between state and federal stablecoin standards is not merely consistent with the text of the GENIUS Act but critical to protecting stablecoin holders and users from the consequences of a regulatory race to the bottom.
The letter states directly:
"Minimizing differences between the substantive standards that apply to a payment stablecoin issuer under a State-level regulatory regime versus the Federal regulatory regime is not only consistent with the plain text of the GENIUS Act, but also critical to safeguard against the risk of a 'race to the bottom' among regulatory regimes, which likely would harm holders and users of payment stablecoins. If a State-level regulatory regime imposes fewer restrictions or requirements on PPSIs in any material way, as compared to the Federal regime, PPSIs will have clear incentives to engage in regulatory arbitrage and seek licensure in that state."
The specific requirements BPI identifies as requiring alignment with no meaningful differences are reserve requirements, capital and liquidity requirements, and the prohibition on the payment of interest or yield on stablecoins.
As covered in our CLARITY Act stablecoin yield provisions analysis, the no-yield rule is the single most commercially contested provision in stablecoin legislation because it defines the competitive boundary between stablecoin products and bank deposits.
BPI's position that state regimes must maintain the same no-yield prohibition as the federal framework reflects the banking industry's view that allowing state-chartered stablecoin issuers to offer yield while federally chartered issuers cannot would create precisely the competitive imbalance that Jamie Dimon identified in his confrontation with Brian Armstrong over the CLARITY Act.
The Historical Precedent BPI Is Citing
The BPI letter draws a cautionary parallel to regulatory arbitrage among state-chartered banks in the 1980s and early 1990s, which contributed to the banking and thrift crisis at the time.
That historical parallel is chosen deliberately and precisely. The savings and loan crisis of the 1980s was substantially driven by deregulation at the state level that allowed state-chartered thrifts to engage in higher-risk activities than federally chartered equivalents, creating an incentive for institutions to seek state charters specifically to escape the restrictions of the federal framework.
The resulting race to the bottom in standards contributed to the failure of more than 1,000 savings and loan institutions and cost US taxpayers an estimated $160 billion in cleanup costs.
BPI is arguing that the GENIUS Act's state opt-in provision creates the structural conditions for exactly that dynamic in the stablecoin market unless Treasury sets the "substantially similar" threshold high enough to prevent states from competing for stablecoin issuer registrations by offering lighter compliance requirements.
As covered in our FDIC AML stablecoin rule analysis, the FDIC has been moving toward bank-equivalent compliance standards for stablecoin issuers at the federal level. BPI's letter is the banking industry's formal request that Treasury ensure state frameworks cannot undercut those standards.
The GENIUS Act Structure That Makes This Debate Consequential
The GENIUS Act provides that certain state qualified payment stablecoin issuers, generally those with issuance of $10 billion or less, may opt for state regulation so long as the state regulatory regime is substantially similar to the federal framework. The Treasury Department is required to establish broad-based principles for determining when a state regime meets that threshold.
That opt-in provision was designed to accommodate smaller and regional stablecoin issuers that argued the full federal framework was disproportionately burdensome relative to their scale and systemic risk.
The community banking sector's concern, as covered in our GENIUS Act loophole analysis, has been that state-chartered stablecoin issuers operating under lighter requirements could attract deposits and payment volume away from community banks without the same consumer protection and safety and soundness obligations.
BPI's letter formalizes those concerns into a specific request: Treasury must set the substantially similar threshold so that state stablecoin regimes have no meaningful differences in substantive requirements from the federal framework. That standard, if adopted, would effectively mean that opting for state regulation provides administrative convenience rather than reduced compliance obligations.
The Broader Regulatory Week Context
The BPI letter arrives in the same week that the Federal Reserve's Waller endorsed dollar stablecoins as a mechanism for extending US monetary policy reach globally, that the Clearing House announced plans to launch a tokenized deposit network in the first half of 2027 to compete with crypto firms amid the stablecoin rise, and that Bank of England official Megan Greene suggested tokenized deposits could ultimately supplant stablecoins over a five-year horizon.
That regulatory and competitive context makes the BPI letter's timing significant beyond the specific GENIUS Act drafting question it addresses. The banking industry is simultaneously arguing for stablecoin regulatory parity through the BPI letter, competing with stablecoin infrastructure through the Clearing House tokenized deposit network, and watching the Revolut US bank and SoFiUSD advance stablecoin banking products that blur the boundary between stablecoin and deposit product that BPI is trying to protect through the no-yield rule.
Conclusion
The BPI letter to Treasury on state stablecoin regulation is the most detailed and consequential formal position the banking industry has taken on the GENIUS Act's state opt-in provision, drawing a direct line from loose state standards to regulatory arbitrage to the systemic outcome that the 1980s banking crisis represents as a cautionary reference.
Treasury's determination of what constitutes a substantially similar state regime will set the competitive floor for every state-licensed stablecoin issuer in the country, and BPI's position that the floor must have no meaningful differences from the federal framework on reserves, capital, liquidity, and no-yield is the banking industry's opening argument in a negotiation that will define the stablecoin market's regulatory architecture for the rest of the decade.
FAQ:
1. What did BPI's letter to Treasury argue about state stablecoin regulation?
BPI's letter to Treasury argued that state-level oversight of payment stablecoins must match the federal regulatory framework under the GENIUS Act in every material respect with no meaningful differences in reserve requirements, capital and liquidity requirements, and the prohibition on the payment of interest or yield on stablecoins, warning that any gap between state and federal standards will incentivize stablecoin issuers to seek licensure in the most permissive state and trigger the same regulatory arbitrage dynamic that contributed to the banking and thrift crisis of the 1980s and early 1990s.
2. What is the difference between the federal GENIUS Act stablecoin framework and the state opt-in option?
The difference between the federal GENIUS Act stablecoin framework and the state opt-in option is that the federal framework applies to all payment stablecoin issuers as the baseline regulatory standard covering reserve requirements, capital and liquidity rules, and a prohibition on paying yield or interest on stablecoins, while the state opt-in allows stablecoin issuers with $10 billion or less in outstanding supply to operate under a state regulatory regime instead of the federal framework, provided that Treasury determines the state regime is substantially similar to federal standards, making the definition of substantially similar the critical variable that determines how much regulatory divergence is permissible.
3. What is the race to the bottom risk that BPI identified in its Treasury letter?
The race to the bottom risk that BPI identified is that if the Treasury's substantially similar standard permits state stablecoin regulatory regimes to impose fewer restrictions or requirements than the federal framework in any material way, stablecoin issuers will have clear financial incentives to seek licensure in whichever state offers the lightest compliance obligations, which would create competitive pressure on other states to lower their own standards to attract stablecoin issuer registrations, ultimately driving compliance standards below the level that adequately protects stablecoin holders and users, replicating the state-chartered bank regulatory competition dynamic that BPI identifies as a contributing factor to the 1980s and early 1990s banking and thrift crisis.
4. Why is the no-yield rule the most commercially significant standard in the BPI letter?
The no-yield rule is the most commercially significant standard in the BPI letter because it directly determines whether stablecoin products compete with bank deposit products for customer balances, since a stablecoin issuer that can pay interest or yield on stablecoin holdings is offering a product that functions like a bank savings account without the deposit insurance obligations, capital requirements, and regulatory examination that banks must maintain to offer equivalent yield products, which is the specific competitive imbalance that BPI and JPMorgan CEO Jamie Dimon have both identified as the central banking industry objection to the CLARITY Act's yield provisions and that BPI is now asking Treasury to prevent at the state level through the substantially similar standard.
5. What historical precedent does BPI cite for the state stablecoin regulatory arbitrage risk?
BPI cites the regulatory arbitrage among state-chartered banks and thrifts in the 1980s and early 1990s as the historical precedent for the state stablecoin regulatory arbitrage risk, when deregulation at the state level allowed state-chartered thrifts to engage in higher-risk activities than federally chartered equivalents and created an incentive for institutions to seek state charters to escape federal restrictions, contributing to the failure of more than 1,000 savings and loan institutions and a US taxpayer cleanup cost estimated at approximately $160 billion, which BPI is arguing would be replicated in the stablecoin market if Treasury sets the substantially similar threshold low enough to allow states to compete for stablecoin issuer registrations by offering lighter compliance requirements.
6. What does the BPI letter mean for the overall GENIUS Act regulatory framework?
The BPI letter means that the banking industry's formal position is that Treasury must interpret the substantially similar standard strictly enough to ensure that state regulation of stablecoin issuers provides administrative convenience rather than reduced compliance obligations relative to the federal framework, which if adopted by Treasury would significantly reduce the practical benefit of the state opt-in for smaller stablecoin issuers and concentrate the competitive differentiation between state and federal oversight at the administrative and examination process level rather than at the level of substantive requirements for reserves, capital, liquidity, and yield prohibition.
