Leverage Rule Rollback Boosts US, UK Bank Lending Firepower by $1.3T
A cornerstone safeguard from the post-2008 era is being recalibrated. US regulators have eased the Enhanced Supplementary Leverage Ratio (ESLR), and S&P Global estimates the change unlocks about $1.3 trillion in additional lending capacity for the largest banks.
The figure reflects balance-sheet room that institutions including JPMorgan Chase, Citibank, Bank of America and Goldman Sachs can now put to work across lending, Treasury purchases and repo activity.
At its core, the ESLR required the biggest banks to hold a minimum capital buffer against total exposures, sweeping in even low-risk holdings such as US Treasuries and repurchase agreements. The revised framework, effective April 1, 2025, lowers the capital that must be set aside for those same low-risk assets by treating Treasuries and repos as less punitive in leverage calculations. Regulators are set to finalize the package on November 25, 2025.
With less capital tied up against Treasuries and repo positions, banks can expand credit and increase participation in funding markets without hitting regulatory constraints as quickly. Forecasts suggest the broader economic impact could approach $4 trillion once credit-multiplier effects are considered, with credit-dependent areas such as defense and infrastructure positioned to benefit.
Macro commentator and BitMEX co-founder Arthur Hayes has described the move as resembling a form of quantitative easing, achieved through capital-rule relief rather than direct Federal Reserve asset purchases.
The implications extend to the UK given the tight links in global banking. Large US lenders have substantial London operations, and UK subsidiaries typically sit within the same group-wide capital and regulatory structures.
For crypto markets, Hayes has tied the ESLR easing to Bitcoin's outlook, arguing that liquidity-sensitive assets tend to respond positively when dollar availability expands. The November 2025 finalization remains a key risk: April's rollout is an interim step, and any material changes in the final rule could force banks to adjust, shifting the $1.3 trillion estimate up or down.
