Dealer Treasury holdings top $700 billion after eSLR recalibration
Federal Reserve Vice Chair for Supervision Michelle W. Bowman stated that recalibrating the enhanced supplementary leverage ratio added nearly $5 trillion in balance sheet headroom for large bank dealers, expanding their Treasury positions from $600 billion to over $700 billion.
Unlocking five trillion dollars in dealer capacity
Speaking at the Atlantic Council, Vice Chair Michelle W. Bowman reported that the revised enhanced supplementary leverage ratio (eSLR) has improved U.S. Treasury market intermediation.
Following the implementation of the new rule in early 2026, total Treasury holdings across primary dealer banks rose from roughly $600 billion to more than $700 billion by late April.
Parent holding companies gained nearly $5 trillion in aggregate leverage headroom in the first quarter of 2026.
Bowman noted that leveraged capacity across global systemically important banks expanded from $1.8 trillion in late 2025 to $6.4 trillion under the recalibrated framework, allowing dealers to absorb market supply and narrow bid-ask spreads.
Replacing the flat two percent buffer
Finalized in November 2025 by the Federal Reserve, FDIC and OCC, the reform replaced the flat two percent leverage buffer with a tailored requirement equal to 50 percent of each firm’s method-1 GSIB surcharge.
For depository subsidiaries, the buffer was set at 50 percent of the parent surcharge, capped at 1.0 percent.
Adopted originally in 2014, the previous eSLR standard had turned into a binding balance sheet constraint during periods of stress.
Seven of the eight U.S. GSIBs opted for early adoption in the first quarter of 2026 ahead of the mandatory April 1 deadline.
Fixing a self-inflicted market distortion
The recalibration rectifies a flawed framework that unnecessarily restricted dealer capacity during periods of market stress.
By tying leverage buffers to systemic surcharges, regulators restored the metric to its proper backstop role.
Yet expanding bank balance sheets alone will not eliminate underlying vulnerabilities in Treasury financing.
