Federal Regulators Propose Sweeping Overhaul of Bank Capital Rules, Offering $87.7 Billion in Relief

U.S. federal banking regulators have scrapped a controversial 2023 capital proposal, replacing it with a sweeping overhaul that will inject an estimated $87.7 billion of capital relief into the banking system. The Federal Reserve, the Federal Deposit Insurance Corporation (FDIC), and the Office of the Comptroller of the Currency (OCC) jointly issued the new framework, effectively lowering Common Equity Tier 1 (CET1) requirements across the board.

The move represents a stark reversal from the agencies' initial attempt to implement the international "Basel III Endgame" standards, which would have increased capital requirements for the largest institutions by nearly 19 percent.[1][2]

By reducing the capital cushion banks must hold against potential losses, the rules free up balance sheets and fundamentally alter the economics of traditional lending. The regulatory relief scales by institution size, offering the most significant proportional benefits to smaller lenders. Global Systemically Important Banks (GSIBs) in Categories I and II will see their CET1 requirements fall by approximately 4.8 percent. Large regional banks in Categories III and IV receive a 5.2 percent reduction, while community banking organizations benefit the most with a projected 7.8 percent drop in required capital.[2]

For the largest institutions, the proposal eliminates a burdensome dual-calculation system that has long complicated capital planning. Instead of calculating risk weights under two parallel methodologies and applying the stricter outcome, Category I and II banks will now use a single "Expanded Risk-Based Approach" (ERBA). This unified framework integrates credit, market, operational, and credit valuation adjustment (CVA) risks, streamlining compliance and providing banks with greater balance sheet flexibility to manage share buybacks, strategic investments, and lending.

A major structural shift occurs in the treatment of mortgage servicing assets (MSAs). The new rules eliminate the punitive deduction framework that previously forced banks to subtract MSA concentrations directly from their Tier 1 capital. Instead, MSAs will receive a flat 250 percent risk weight. Regulators explicitly designed this change to encourage regulated banks to stay active in mortgage origination and servicing, reversing a decade-long trend of mortgage activity migrating to non-bank lenders.[1]

Corporate lending also receives more favorable treatment under the revised Standardized Approach. The risk weight applied to most corporate loan exposures will drop from 100 percent to 95 percent. This 5 percent reduction improves the profit margins of commercial lending for traditional banks, empowering them to compete more fiercely against the booming private credit and alternative asset management sectors that have increasingly dominated middle-market corporate debt.[2][3]

The overhaul is not entirely deregulatory, however. The proposal mandates that Category III and IV regional banks—those with assets over $100 billion—must now include Accumulated Other Comprehensive Income (AOCI) in their regulatory capital calculations. This forces regional lenders to recognize unrealized losses on available-for-sale securities, a vulnerability that contributed to the regional banking crisis of 2023. To soften the immediate impact, regulators have provided a five-year phase-in period starting in 2027.[3]

Market risk methodologies are also being modernized. The framework shifts the measurement of trading book risks from a Value-at-Risk (VaR) model to an expected shortfall approach, while introducing explicit capital requirements for CVA risk—the risk of loss arising from changes in the creditworthiness of a derivative counterparty. These technical adjustments aim to better capture tail risks and market liquidity during severe downturns without overly penalizing routine trading activities.

The proposals represent a total reset of the U.S. implementation of global capital standards, prioritizing alignment with international peers while restoring risk-based regulatory tailoring. With the public comment period open until June 18, 2026, financial institutions are currently modeling the exact impacts on their balance sheets. If finalized, the rules will take effect two calendar quarters after adoption, reshaping the competitive landscape of American finance and ensuring that traditional lending remains anchored in the regulated banking sector.[2][3]
