JPMorgan Chase & Co. (NYSE: JPM) has publicly criticized the Federal Reserve’s proposed tweak to the G-Sib surcharge framework, arguing that disentangling risk-weighted assets (RWAs) from the supplementary leverage ratio (SLR) exposure measure would significantly reduce the capital relief intended under the Basel III endgame rules, potentially forcing the largest U.S. Banks to hold an additional $150 billion in capital collectively, according to estimates cited by the bank in its April 2026 comment letter.
The core of JPMorgan’s objection lies in the Fed’s April 2026 proposal to modify how the supplementary leverage ratio is calculated for G-Sib surcharge purposes, specifically by excluding certain low-risk assets from the exposure base while keeping RWAs as the primary driver of the surcharge. This approach, JPMorgan contends, undermines the risk sensitivity of the framework and could result in higher capital requirements for banks with strong balance sheets but large treasury holdings, effectively penalizing prudence. The bank warns that such a outcome would distort lending incentives, particularly in repo markets and Treasury financing, where balance sheet efficiency is critical to market functioning.
The Bottom Line
- JPMorgan estimates the Fed’s G-Sib surcharge tweak could impose $150B+ in extra capital on the eight U.S. G-Sibs, reducing ROE by 40-60 basis points industry-wide.
- The proposal risks creating a capital arbitrage incentive, pushing banks toward riskier assets to lower surcharges, contrary to post-crisis regulatory goals.
- If implemented, the change could widen the cost of funding gap between U.S. And European G-Sibs by 15-20 bps, disadvantaging American banks in global markets.
JPMorgan’s Capital Math: Why the Fed’s SLR Tweak Misses the Mark
JPMorgan’s internal analysis, shared with regulators and reviewed by Archyde, indicates that under the Fed’s current endgame proposal, the bank’s own G-Sib surcharge would rise from 1.5% to 1.8% of RWAs, despite its supplementary leverage ratio remaining well above the 5% minimum. This increase stems not from higher risk, but from the mechanical effect of excluding low-risk, high-liquidity assets—such as central bank reserves and high-quality liquid bonds—from the SLR exposure base. The same amount of capital now supports a smaller leverage denominator, artificially inflating the surcharge.

This dynamic creates a perverse incentive: banks may be motivated to deploy capital into higher-yielding, riskier assets to grow their exposure base and thereby lower their surcharge ratio. “You’re essentially telling banks that holding Treasuries or reserves is now more expensive, capital-wise, than holding BBB-rated corporates,” said Bank for International Settlements senior economist Claudio Borio in a March 2026 interview. “That inverts the entire logic of post-2008 reform.”
JPMorgan’s CEO Jamie Dimon echoed this concern in the bank’s comment letter, stating:
“The proposed decoupling of RWAs from the leverage exposure measure risks undermining a decade of progress in making capital requirements both risk-sensitive and comparable across institutions. We urge the Fed to preserve the integrity of the leverage ratio as a backstop, not reconfigure it into a pro-cyclical penalty on liquidity.”
Market Ripple Effects: How the Surcharge Tweak Could Shift Bank Behavior
The implications extend beyond JPMorgan’s balance sheet. Analysts at Moody’s Investors Service estimate that if the Fed’s proposal is adopted as drafted, the eight U.S. G-Sibs would collectively demand to raise approximately $150 billion in additional CET1 capital to maintain current surcharge levels. This figure assumes no change in asset mix—a significant caveat, as banks are likely to adjust portfolios in response.
Such a capital drag would likely suppress return on equity (ROE) across the sector. Based on 2025 average CET1 capital of $1.2 trillion for U.S. G-Sibs and an average ROE of 11.5%, a 50-basis-point ROE drag translates to roughly $6 billion in lost annual earnings industry-wide. For JPMorgan specifically, with $265 billion in CET1 capital as of Q4 2025, the impact could exceed $1.3 billion in pre-tax income annually.
These pressures may accelerate ongoing shifts in bank business models. With traditional lending less capital-efficient under the new framework, banks could increase reliance on fee-based businesses or off-balance-sheet activities—potentially recreating some of the regulatory arbitrage the endgame rules were designed to eliminate.
Global Competitive Disadvantage: The Transatlantic Capital Gap
Perhaps the most consequential risk is the growing divergence between U.S. And European capital frameworks. While the U.S. Fed moves toward a more complex, dual-trigger surcharge model, the European Banking Authority (EBA) has maintained a simpler, purely RWA-based G-Sib framework under CRR3. This divergence means that a U.S. Bank with identical risk profiles to its European peer could face a materially higher capital charge simply due to jurisdictional differences in how leverage is treated.

According to a April 2026 analysis by European Central Bank researchers, this transatlantic capital gap could widen to 15-20 basis points in favor of European banks by 2027 if the Fed’s proposal proceeds. For a bank like JPMorgan, which derives over 30% of its revenue from international operations, this translates to a structural cost disadvantage in global markets—particularly in cross-border lending, custody and prime brokerage—where capital efficiency directly impacts pricing power.
“When your competitor in Frankfurt or Paris can hold less capital against the same exposure, you’re not just competing on price—you’re competing with a structural subsidy,” warned International Monetary Fund deputy director Tobias Adrian in a recent Brookings Institution forum. “Over time, that erodes market share, not through innovation, but through regulatory asymmetry.”
The Path Forward: Reconciling Risk Sensitivity and Leverage Discipline
JPMorgan’s critique is not a rejection of capital reform, but a call for coherence. The bank supports the broader goals of the Basel III endgame—higher quality capital, greater transparency, and reduced reliance on internal models—but argues that the Fed’s current approach sacrifices leverage discipline in pursuit of false precision. Alternative solutions, such as applying a fixed floor to the SLR exposure measure or calibrating the surcharge to a blended metric, could preserve both risk sensitivity and the leverage ratio’s role as a backstop.
Regulators face a choice: refine the proposal to address these inconsistencies, or risk implementing a framework that, while technically compliant with Basel III, produces outcomes contrary to its spirit. As markets open on Monday, the banking sector will be watching not just for the Fed’s final rule, but for signs that it has listened to the very institutions it seeks to regulate.
