Stablecoin Yield Regulation and the Battle for Capital: Banks vs. Crypto in 2025

The regulatory landscape for stablecoins has undergone a seismic shift in 2025, with the U.S. GENIUS Act and the EU's Markets in Crypto-Assets (MiCA) framework redefining the rules of engagement for institutional and retail capital. These policies, while aimed at stabilizing the volatile crypto market, have inadvertently intensified the long-standing tension between traditional banking institutions and crypto-native innovators. As capital allocation strategies evolve under these new rules, the clash between centralized finance (TradFi) and decentralized finance (DeFi) has become a defining feature of the post-2025 financial ecosystem.

Regulatory Frameworks: A Double-Edged Sword

The U.S. GENIUS Act, enacted in July 2025, mandates that stablecoin issuers maintain a 1:1 reserve ratio with high-quality liquid assets (HQLA), including U.S. Treasuries and bank deposits, while explicitly prohibiting interest payments on stablecoin holdings according to Visa's analysis. This has forced major issuers like Circle (operator of USDC) to pivot their revenue models toward interest income from reserve assets, exposing them to interest rate volatility. For instance, a 100 basis point decline in rates could slash Circle's annual reserve income by $441 million. Meanwhile, the EU's MiCA regulation allows up to 30-60% of stablecoin reserves to be held in bank deposits, depending on issuer size, introducing credit risk but offering greater flexibility for yield generation.

These frameworks have created a paradox: while they aim to mitigate systemic risks, they have also incentivized traditional banks to enter the stablecoin arena. JPMorgan's My OnChain Net Yield Fund and Société Générale's EURCV stablecoins exemplify how banks are leveraging regulatory clarity to compete with crypto-native platforms. This shift has not only diversified capital allocation but also redefined the role of banks as intermediaries in tokenized finance.

Institutional Capital: A New Equilibrium

Institutional investors have responded to the regulatory clarity by reallocating capital toward compliant stablecoin ecosystems. According to a Bloomberg report, 86% of institutional investors either hold digital assets or plan to do so, with 68% investing in Bitcoin exchange-traded products (ETPs) by 2025. The total assets under management (AUM) of crypto ETFs reached $191 billion, with institutions accounting for 24.5% of this growth. This surge reflects a broader institutional view of Bitcoin as a strategic asset rather than a speculative gamble, with 94% of institutional investors recognizing blockchain's long-term value.

However, the regulatory constraints on yield-bearing stablecoins have created friction. Traditional banks, wary of deposit flight to high-yield crypto alternatives, have lobbied for stricter oversight. For example, Citadel Securities sent a strongly worded letter to the SEC, urging it to reject proposed exemptions for crypto firms, arguing they undermine market safeguards. Conversely, crypto-native platforms like Ethena's USDe, which generates yield through staking and derivatives, have attracted capital by offering returns unattainable in traditional banking. This dichotomy underscores a fundamental conflict: banks prioritize stability and liquidity, while crypto innovators emphasize yield and efficiency.

Retail Adoption: The Democratization of Finance

Retail investors have also been reshaped by the regulatory environment. Stablecoin supply reached $238 billion in August 2025, driven by their use in payments, settlements, and tokenization. Fintech integrations, such as Stripe and Revolut enabling USDC and USDT for real-world transactions, have normalized stablecoins as infrastructure for everyday finance. According to Chainalysis, stablecoin monthly active users grew by 25% in 2025, reflecting their appeal as a low-volatility alternative to speculative crypto assets.

Yet, the prohibition of yield on stablecoins under the GENIUS Act and MiCA has limited their utility for retail users seeking passive income. This gap has been partially filled by regulated real-world asset (RWA) tokenization, as seen in Singapore's stablecoin laws, which redirect innovation toward treasuries and credit instruments. While this fosters financial inclusion, it also highlights the regulatory arbitrage risks inherent in a fragmented global framework.

The Tensions: Legal Battles and Policy Rifts

The regulatory push has not been without conflict. The SEC's ongoing lawsuits with crypto firms, including the landmark SEC v. Ripple Labs case, have set precedents for classifying digital assets as securities. Meanwhile, the Trump administration's pro-crypto stance has emboldened industry players, but traditional banks continue to resist. For instance, the Federal Reserve's 2025 report noted that stablecoin reserves held as bank deposits could increase liquidity risk and funding costs for institutions.

Legal battles are intensifying. Citadel Securities' opposition to crypto exemptions and the SEC's enforcement actions against Coinbase and others signal a broader policy rift. As stated by a Katten Muchin partner, "The crypto industry and banks are locked in a battle over the future of digital finance rules, with competing visions for regulation at the agency level." This tension is likely to escalate in 2026, as both sides vie for influence in shaping the next phase of financial infrastructure.

Conclusion: A New Financial Order

The 2025 regulatory shifts have catalyzed a transformation in capital allocation, with traditional banks and crypto innovators vying for dominance in a redefined market. While the GENIUS Act and MiCA have provided much-needed clarity, they have also exposed structural weaknesses in both systems. For investors, the key takeaway is that the future of finance will be defined by hybrid models-where regulated stablecoins bridge the gap between TradFi and DeFi. However, the path forward remains fraught with legal and policy challenges, as the battle for control over capital allocation intensifies.
