U.S. Stablecoin Regulation and Its Implications for Bank Funding and Credit Risk

The passage of the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act in July 2025 marked a pivotal shift in the regulatory landscape for stablecoins, reshaping the dynamics between traditional banking systems and emerging digital asset ecosystems. This legislation, which mandates 1:1 reserve backing for payment stablecoins and prohibits interest-bearing models, has triggered a strategic reallocation of capital across financial institutions and investors. As stablecoins gain regulatory clarity, their potential to displace traditional bank deposits and alter credit risk profiles has become a focal point for policymakers and market participants alike.

Regulatory Framework and Capital Reallocation

The GENIUS Act requires stablecoin issuers to maintain reserves in high-quality liquid assets such as U.S. Treasuries, FDIC-insured deposits, and overnight reverse repurchase agreements according to Federal Reserve research. This framework aims to mitigate systemic risks while fostering innovation. However, the act's exclusion of capital and liquidity requirements for nonbank issuers has created a regulatory asymmetry. For instance, major banks like JPMorgan and BNY Mellon have begun integrating stablecoins into their infrastructure to facilitate cross-border payments and real-time transactions, while smaller institutions face pressure to adapt or risk losing market share.

Data from the Treasury Department suggests that up to $6.6 trillion in non-interest-bearing transactional deposits could shift to stablecoin ecosystems if interest-bearing models are not restricted. This potential outflow underscores the tension between stablecoin adoption and traditional banking. Banks are responding by exploring tokenized deposits-regulated alternatives that offer competitive yields while retaining deposit insurance as reported by Gibson Dunn. For example, the Federal Reserve's conditional approval of limited-purpose payment accounts for eligible institutions highlights efforts to balance innovation with financial stability.

Credit Risk and Funding Structure Impacts

The displacement of bank deposits by stablecoins poses significant credit risk challenges. A Federal Reserve analysis indicates that stablecoin adoption could lead to a more concentrated, uninsured deposit base, increasing liquidity risk and funding costs for banks. This is particularly acute for smaller institutions lacking the technological infrastructure to compete in a digital-first environment. For instance, a study by CRA Vice President Viktor Tsyrennikov found that community banks could face up to a 6.8% deposit loss in extreme scenarios, though no material impact has been observed in current data.

Moreover, the GENIUS Act's prohibition on interest-bearing stablecoins has inadvertently incentivized affiliated platforms to offer yield-bearing programs through opaque mechanisms, such as staking rewards or liquidity provision. This regulatory arbitrage risks creating shadow-banking systems that bypass traditional credit creation channels. The Ethena (USDe) de-peg event in October 2025 exemplifies the fragility of such models, as rapid loss of confidence led to systemic instability.

Strategic Adaptation by Banks and Investors

In response to these challenges, banks are recalibrating their capital strategies. The Office of the Comptroller of the Currency (OCC) has approved five national trust bank charters focused on digital assets, signaling a more open supervisory stance. Similarly, the Federal Reserve's rescinding of restrictive policies on Section 9(13) of the Federal Reserve Act allows state member banks to pursue crypto-related activities under safety-and-soundness principles. These regulatory shifts enable banks to custody stablecoins and leverage blockchain technology, potentially offsetting deposit losses.

Institutional investors, meanwhile, are reallocating capital toward U.S. stablecoins as a result of the GENIUS Act's enhanced transparency and audit requirements. Compliance costs for mid-sized issuers-estimated at $2–$5 million annually-have not deterred institutional interest, as the act's prohibitions on algorithmic stablecoins reduce market volatility. This trend is evident in partnerships between stablecoin issuers and fintech platforms, which are expanding cross-border payment solutions and treasury management tools.

Conclusion

The GENIUS Act has catalyzed a paradigm shift in the interplay between stablecoins and traditional banking. While regulatory clarity has spurred innovation, it has also exposed vulnerabilities in credit risk management and funding structures. Banks must navigate the dual imperatives of adapting to digital transformation and preserving their role as core financial intermediaries. For investors, the act's framework presents opportunities to capitalize on stablecoins as regulated, liquid instruments, provided systemic risks are mitigated through ongoing oversight. As the financial ecosystem evolves, the strategic reallocation of capital will hinge on the ability of institutions to balance innovation with prudence.
