US debt load could undercut Warsh's plan to shrink Fed balance sheet

• Research shows U.S. Treasuries have lost about 40 basis points of their 'convenience yield' since the Fed began balance sheet reduction in 2022, meaning higher borrowing costs for the government
• The federal deficit is projected at 5.8% of GDP for fiscal 2026, well above the 50-year average of 3.8%, creating pressure for continued Treasury issuance
• The Fed lacks a clear framework for quantitative easing and tightening, with no agreement on how bond purchases affect the economy or guidelines on when and how much to buy or sell

Summary: Warsh's Fed Balance Sheet Reduction Plans Face Debt Challenges

Kevin Warsh, confirmed Wednesday as the next Federal Reserve Chair, aims to shrink the Fed's market footprint and reduce its $6.7 trillion balance sheet (down from a $9 trillion peak in 2022). However, analysts warn this strategy faces significant obstacles from rising U.S. federal debt and declining appeal of Treasury bonds.

Key Challenges:

Stanford finance professor Hanno Lustig's research suggests developed markets like the U.S. have lost their "convenience yield"—the traditional rate advantage for risk-free government debt. St. Louis Fed research found the convenience yield fell 40 basis points when balance sheet reduction began in 2022, forcing the U.S. to pay investors more.

The Congressional Budget Office projects a fiscal 2026 deficit of 5.8% of GDP, well above the 50-year average of 3.8%, with rising interest costs driving it higher.

Technical Complications:

Bank Policy Institute analysis indicates reducing the balance sheet by another $2 trillion could affect the Fed's policy rate anywhere from a 0.84-percentage-point cut to a possible hike, depending on execution and Treasury Department coordination.

The Fed lacks a formal framework for quantitative easing and tightening, with former Fed adviser Ellen Meade estimating a 9-12 month process needed to establish guidelines.

Opposition:

Fed Governor Christopher Waller called proposals to significantly curtail holdings "extremely inefficient and stupid." A Brookings Institution survey of 29 analysts found most believe the current balance sheet size doesn't threaten U.S. economic growth or financial stability.

Warsh has criticized the Fed's expanding role since serving as governor over a decade ago, but implementing his vision may prove difficult amid current fiscal dynamics.
