Key Takeaways:
Wall Street's biggest banks spent years lobbying as one bloc to soften U.S. capital rules. With the finish line in sight, that alliance has fractured.
Wall Street's largest banks have fractured their long-standing lobbying alliance on capital rules as the Federal Reserve's Basel III endgame rewrite approaches its final stage in 2026, with diverging interests now splitting the industry.
The original Basel III endgame proposal, unveiled by the Federal Reserve, FDIC, and Office of the Comptroller of the Currency in July 2023, would have raised capital requirements for the eight largest U.S. banks by roughly 16 percent on average, according to the agencies' own estimates. After two years of intense industry pushback and a significant softening of the draft, the final rule now sits at a point where individual banks calculate their own winners and losers.
The fracture reflects a widening gap between banks that would face relatively modest capital increases under the revised framework and those that would still absorb meaningful hits to their capital ratios. Institutions with large trading operations and significant market-making businesses face the steepest potential increases, while more traditional commercial lenders with simpler balance sheets would see comparatively lighter impacts. This divergence has turned what was once a unified industry front into a series of competing positions on how quickly the rule should be finalized and what concessions remain on the table.
The stakes are substantial. Every percentage point of additional capital requirement translates into billions of dollars in reduced lending capacity, lower returns on equity, and diminished capacity for share buybacks across the largest U.S. banks. With the rule expected to be finalized before the end of 2026, the outcome will shape capital allocation decisions, dividend policies, and stock valuations across the sector for years to come.
The original proposal drew more than 4,000 comment letters from banks, trade groups, and lawmakers, making it one of the most contested rulemakings in the Fed's history. Fed Chair Jerome Powell signaled in late 2024 that the rules would be substantially revised, and the subsequent draft reflected a significant retreat from the initial framework.
The split among banks has become increasingly visible in recent months. Some of the largest institutions, particularly those that would benefit from a more predictable regulatory environment, are now pressing for the rule to be finalized quickly. Others, facing steeper capital requirements, continue to push for additional modifications, arguing that the revised framework still overstates risk in certain trading and lending activities.
This is not the first time the banking industry has seen its lobbying coalition fracture. During the 2018 Dodd-Frank rollback, regional banks broke from the largest institutions to secure relief from stricter stress-testing requirements, while the biggest banks focused on changes to the Volcker Rule. That split ultimately produced a bill that passed with bipartisan support, though the largest banks received less relief than they had initially sought.
For investors, the key question is how the final rule affects capital return capacity. Any incremental capital requirement would directly reduce the capacity for buybacks and dividends, with the impact varying significantly by institution. JPMorgan Chase, Bank of America, Citigroup, and Goldman Sachs — the four largest U.S. banks by assets — would each face different capital outcomes depending on the composition of their balance sheets.
The competitive implications extend beyond shareholder returns. Banks facing steeper capital increases would need to either raise additional equity, reduce risk-weighted assets, or accept lower returns on equity. That could give simpler-balance-sheet lenders a cost advantage in certain lending markets, potentially reshaping competitive dynamics across the sector.
The Federal Reserve has indicated it aims to finalize the rule before the end of 2026, though the timeline could slip depending on the outcome of the second comment period and political considerations in Washington. Banks are now positioning for a range of scenarios, from a relatively benign final rule that preserves most of their capital return capacity to a more stringent outcome that forces balance-sheet restructuring.
