Fed: eSLR boosts Treasury market

Highlights

Seven of eight U.S. GSIBs adopted the recalibrated eSLR early in Q1 2026, increasing parent bank holding company eSLR headroom by nearly $5 trillion across six major dealers.
U.S. dealer Treasury positions rose from about $600 billion to over $700 billion by end of April 2026, concentrated among firms previously operating with lower capital buffers.
Leveraged capacity at GSIBs surged from $1.8 trillion in Q4 2025 to $6.4 trillion post-rule, with leveraged exposure rising by $900 billion, improving Treasury and repo market liquidity.

Early effects of the 2025 eSLR changes

As reported by the Federal Reserve Board, Vice Chair for Supervision Michelle Bowman says the recalibrated enhanced supplementary leverage ratio is already improving Treasury market functioning by reducing balance sheet constraints on major bank dealers.

In remarks prepared for the Atlantic Council 2026 CEO & Senior Management Summit in Washington, D.C., Bowman says the revised rule is designed to restore the eSLR to its intended role as a backstop to risk-based capital requirements, rather than a binding limit that discourages lower-risk activities such as Treasury market intermediation.

The Federal Reserve Board, the Federal Deposit Insurance Corporation and the Office of the Comptroller of the Currency finalized the changes in November 2025. The rule took effect on April 1, 2026, with optional early adoption beginning on January 1, 2026, and seven of the eight U.S. global systemically important banks adopted it in the first quarter.

Bowman says estimates show the parent bank holding companies of six dealers gained nearly $5 trillion in aggregate eSLR headroom in the first quarter of 2026. Supervisory data also shows dealers' total Treasury positions rose from about $600 billion at the start of the modification period to more than $700 billion by the end of April, with the increase concentrated among firms that had previously operated with the lowest buffers.

A forthcoming research note from Federal Reserve Board staff similarly finds that dealers' Treasury positions increased after the new rule was implemented, particularly at banks that had been more constrained under the prior framework.

Treasury market impact and regulatory message

Bowman says market outreach also points to lower capital constraints and greater use of balance sheet capacity across U.S. GSIBs. One dealer cited in her remarks says leveraged capacity at GSIBs rose from $1.8 trillion in the fourth quarter of 2025 to $6.4 trillion after the rule took effect, while leveraged exposure across the group increased by about $900 billion.

She says some institutions directly linked higher Treasury holdings and repo market activity to the recalibration, and that market participants told the Fed the lower eSLR requirements improved Treasury and money market liquidity. Bowman adds that stronger dealer capacity is helping absorb flows during heavy Treasury issuance, damp intraday volatility around auctions and support price stability during periods of elevated supply.

Her remarks also say dealers have expanded Treasury holdings while hedging with short Treasury futures positions, likely taking on exposures previously held more heavily by hedge funds in the cash-futures basis trade. Bowman argues that this shift can reduce the market's reliance on highly leveraged investors that may be more vulnerable to funding or derivatives shocks.

More broadly, Bowman presents the eSLR revision as evidence that financial rules should be reviewed and modernized when data shows they are no longer working as intended. She says the experience demonstrates that targeted recalibration can improve both market resilience and the efficiency of regulation, especially during periods of stress when liquidity is most important.

In our earlier coverage of Hong Kong’s U.S. dollar peg and the fallout from the Fed’s post-2022 tightening cycle, we explained how higher U.S. rates quickly fed into local financial conditions. We noted the pressure this created across property, equities, and retirement savings, while also highlighting how more attractive Treasury yields were starting to pull long-term investors toward U.S. government bonds.
