Kevin Warsh, selected by the Trump administration to head the Federal Reserve, has long advocated for shrinking the central bank’s massive portfolio of bonds and cash. However, financial experts warn that achieving this goal would prove extremely difficult under current banking regulations and monetary policy frameworks.
The Federal Reserve’s current approach to controlling interest rates relies heavily on banks maintaining substantial cash reserves. This system creates natural limits on how much the Fed can reduce its holdings while still maintaining stable money markets and effective monetary policy control.
According to BMO Capital Markets analysts, reducing the Fed’s market presence significantly faces major hurdles. “There isn’t a straightforward path to a smaller Fed footprint in financial markets,” they noted. “The reality is that much smaller holdings may not be feasible unless there are regulatory reforms that reduce banks’ demand for reserves – a process that will take quarters, not months, to unfold.”
Two prominent economists, Stephen Cecchetti from Brandeis University and Kermit Schoenholtz from New York University, acknowledged concerns about large central bank balance sheets in a February 8th blog post. “We appreciate that when a central bank’s balance sheet is large, it facilitates government financing that is highly undesirable,” they wrote, noting it also interferes with financial markets. However, they cautioned that “shrinking the balance sheet significantly would expose short-term markets to substantial volatility risk – a cure potentially worse than the disease.”
Warsh, who previously served as a Fed governor from 2006 to 2011, was nominated last month to replace current Chair Jerome Powell when his term expires in May. Throughout his career, he has consistently criticized the central bank’s expanded role in financial markets.
The Fed’s holdings grew dramatically during two major crisis periods. First during the 2008 financial crisis, and again during the COVID-19 pandemic in 2020, the central bank purchased massive amounts of Treasury and mortgage bonds to stabilize markets and provide economic stimulus when interest rate cuts alone proved insufficient. These purchases pushed Fed holdings to a peak of $9 trillion in spring 2022.
Currently, the Fed manages this system through automated rate tools established in 2019 that can both absorb and provide cash to financial markets, along with emergency lending facilities when needed. This framework helps maintain the Fed’s target interest rate at desired levels.
Last summer, Warsh criticized the Fed’s approach during a period when the central bank was reducing its holdings through “quantitative tightening” or QT, which began in 2022. This process aimed to remove excess cash from the financial system and continued until money market rates began rising and financial firms needed to borrow directly from the Fed to meet their cash needs.
The Fed successfully reduced its holdings from the 2022 peak to the current level of $6.7 trillion before ending the reduction process. The central bank is now temporarily increasing holdings again as a technical measure to manage money market rates through the spring.
Warsh argues that large Fed holdings distort financial markets and benefit Wall Street at Main Street’s expense. He believes further reductions could allow the Fed to set lower interest rates than would otherwise be possible, directing more liquidity to the broader economy.
The fundamental challenge to Warsh’s vision lies in banking regulations that require institutions to maintain substantial reserves. Reducing Fed holdings by removing liquidity from the financial system could undermine the central bank’s ability to control interest rates and fulfill its inflation and employment mandates.
Morgan Stanley analysts noted on February 6th that regulatory changes could reduce banks’ liquidity needs, but warned of trade-offs. “Lower liquidity buffers could increase financial stability risks,” they cautioned.
J.P. Morgan economists Jay Barry and Michael Feroli suggested Wednesday that improving the Fed’s on-demand lending operations might encourage banks to hold less cash. However, they concluded, “we do not think it is likely the Fed can restart QT.”
Some analysts believe closer coordination between the Treasury Department and the Fed could create room for smaller Fed holdings.
Despite Warsh’s public positions, many Fed observers expect practical realities will moderate any dramatic policy shifts. Evercore ISI analysts wrote Tuesday that “we think he will not push for a return” to pre-financial crisis monetary policy, when the Fed operated with limited market liquidity and managed rates through frequent interventions amid significant interest rate volatility.
They also ruled out resuming quantitative tightening, arguing it would signal reluctance to use balance sheet tools in future crises, potentially driving up borrowing costs immediately.
