The Federal Reserve's revised Basel III Endgame proposal reached a key milestone on June 18, when the comment deadline prompted coordinated responses from major financial industry groups including the International Swaps and Derivatives Association, the Securities Industry and Financial Markets Association, the Institute of International Finance, and the Futures Industry Association. The submissions followed nearly three years of industry lobbying, regulatory revisions, quantitative studies, and political debate since the original 2023 proposal triggered fierce opposition from banks, dealers, exchanges, and clearing firms. The revised framework, unveiled in March 2026, would reduce large-bank capital requirements by approximately 4.8% compared with current requirements, a dramatic shift from the original proposal's direction. Industry groups now broadly support the framework's direction while urging further refinements to market risk calculations, clearing incentives, and Treasury market liquidity provisions before the rules are finalized. The remaining debate centers on whether the final framework accurately measures economic risk or continues to overstate exposures in key trading and clearing activities.
Federal Reserve Revises Capital Requirements from 20% Increase to 4.8% Reduction
The Basel III Endgame debate began in 2023 when U.S. regulators proposed sweeping revisions to bank capital requirements following a series of regional bank failures and ongoing international efforts to complete post-crisis banking reforms. The original proposal was widely criticized across Wall Street, with banks arguing that the framework significantly overstated risk, duplicated existing safeguards, and would force institutions to hold substantially more capital against trading, lending, and market activities.
When regulators unveiled a revised proposal in March 2026, they estimated the new framework would reduce large-bank capital requirements by approximately 4.8% compared with current requirements. The revised framework eliminates several features that banks considered unnecessarily punitive, streamlines capital calculations, and introduces more risk-sensitive treatment across multiple exposure categories. According to Reuters, large banking organizations estimate that the combined effect of proposed changes to Basel III, stress testing, and G-SIB surcharge calculations could reduce capital requirements by approximately $22 billion across the largest U.S. institutions.
ISDA Quantitative Study Shows Market Risk Capital Impact Dropped Significantly
The International Swaps and Derivatives Association conducted a quantitative impact study using data from the eight U.S. global systemically important banks. ISDA found regulators have significantly reduced the projected impact of the Fundamental Review of the Trading Book, commonly known as FRTB. According to ISDA, the original proposal would have increased market risk capital by between 73% and 101%, depending on whether banks used internal models or standardized calculations.
The revised proposal substantially reduced those figures. Under the FRTB standardized approach, the projected increase fell from 101% to 89%. Under the internal models approach, the projected increase dropped from 73% to 30%. ISDA described the changes as a significant improvement and credited regulators for increasing the viability of internal models. The organization's primary concern involves cross-product netting under the standardized approach for counterparty credit risk, with ISDA arguing the proposal still overstates risk by failing to fully recognize offsets between derivatives and financing transactions such as repos.
Industry Groups Warn Treasury Market Liquidity May Be Affected
In their joint submission, ISDA, SIFMA, and the IIF argue that capital requirements directly influence the pricing and availability of market intermediation, client financing, hedging services, and liquidity provision. The groups contend that more risk-sensitive rules support deeper and more efficient markets while reducing costs for end users. They warn that certain elements of the current proposal could still discourage market-making activity and reduce dealer capacity during periods of market stress.
The Financial Times reported industry groups are specifically warning regulators about potential consequences for Treasury market liquidity. The U.S. Treasury market serves as the foundation of global fixed-income trading and collateral management. For policymakers, the challenge is balancing financial resilience with market efficiency, as capital requirements that are too low can increase systemic risk while requirements that are too high can reduce the willingness of banks to provide liquidity during volatile periods.
FIA Supports Central Clearing Recognition in Revised Framework
The Futures Industry Association broadly supports the revised Basel III framework and says regulators have made meaningful progress in recognizing the role clearing plays in reducing systemic risk. FIA specifically welcomed the exclusion of client-facing derivative exposures from the Credit Valuation Adjustment framework, recognition of netting arrangements, and the introduction of cross-product netting concepts. FIA also praised changes to the Federal Reserve's proposal governing capital surcharges for U.S. global systemically important banks, describing those changes as an important step toward preventing bank capital rules from discouraging central clearing.
Jacqueline Mesa, FIA's Chief Operating Officer and Senior Vice President of Global Policy, said regulators appropriately recognize the importance of central clearing but should go further in recognizing risk offsets across related positions. FIA argues capital requirements should reinforce the objective of promoting central clearing rather than undermine it. The association is seeking additional revisions to cross-product netting methodologies, cross-margining treatment, G-SIB surcharge calculations, and operational requirements governing cleared transactions.
June 18 Comment Deadline Marks Final Consultation Phase
The June 18 comment deadline may represent the final major consultation stage before regulators begin drafting a final rule. Unlike previous rounds of feedback, industry groups are no longer attempting to stop the framework. Instead, they are making targeted requests focused on market risk calculations, clearing incentives, Treasury market liquidity, derivatives netting, and G-SIB surcharge calibration.
Regulators have already softened several provisions, reduced projected capital impacts, simplified calculations, and introduced more risk-sensitive treatment in multiple areas since 2023. The debate has moved from whether Basel III Endgame should proceed to how precisely it should be calibrated. The final rules will influence the economics of trading, market-making, repo financing, derivatives clearing, Treasury market liquidity, and client hedging activity across the U.S. financial system.
