New Study Outlines Ways Federal Reserve Could Shrink Its $6.6 Trillion Holdings

A Stanford professor's research published by the Brookings Institution details how the Federal Reserve could reduce its massive balance sheet through regulatory adjustments and payment system changes. The study comes as new Fed leadership critical of large central bank holdings prepares to take over.

A new study released Wednesday by the Brookings Institution outlines several strategies the Federal Reserve could employ to reduce its massive $6.6 trillion balance sheet through regulatory adjustments and operational changes.

Stanford University Graduate School of Business professor Darrell Duffie authored the research, which maps out a multi-faceted approach that would require significant time to implement. According to Duffie, the primary objective in shrinking the Fed’s holdings involves reducing financial institutions’ substantial demand for reserves.

The professor suggests several methods to decrease this demand, including relaxing liquidity requirements so banks feel more comfortable maintaining smaller cash reserves. Additionally, modifications to the Fed’s Fedwire payment system could better coordinate incoming and outgoing transactions for financial firms, reducing their need to hold excess funds.

Other proposed changes include adjusting the interest rates paid to financial institutions, potentially lowering compensation for reserves above certain thresholds. The Fed could also increase its use of temporary open market operations for liquidity management rather than relying on the current automated approach.

“I’m not taking a stand on whether the Fed should reduce its balance sheet,” Duffie explained during a virtual press conference. “That’s a big cost-benefit analysis that I’m leaving up to the Fed.”

However, Duffie acknowledged that “the benefits of a large balance sheet are quite tangible,” noting that abundant system liquidity provides financial stability advantages and supports the Fed’s monetary policy objectives effectively.

“The costs are more intangible and sometimes verge into politics,” he added, referencing concerns about how extensive Fed asset holdings might impact the central bank’s independence.

This research emerges as Kevin Warsh, a vocal opponent of large Fed balance sheets, prepares to replace current Chair Jerome Powell when his term concludes in May. Treasury Secretary Scott Bessent has similarly criticized the Fed’s substantial presence in asset markets.

The Fed’s current holdings represent a dramatic expansion from economic crises and the central bank’s responses. Balance sheet size has grown from under $1 trillion before the 2008 financial crisis to today’s $6.6 trillion, down from a 2022 peak of $9 trillion.

These holdings expanded through multiple episodes where the Fed purchased Treasury and mortgage securities aggressively to stabilize disrupted markets and provide economic stimulus beyond what traditional short-term rate adjustments could achieve.

Bond purchases resulted in massive increases in bank reserves, as institutions selling securities to the Fed received newly created central bank funds. Simultaneously, post-crisis regulations have encouraged banks to maintain higher reserve levels.

The Fed has developed various tools to manage short-term interest rates effectively, maintaining strong control over the federal funds rate, its primary monetary policy instrument.

However, removing too much liquidity from the system risks undermining the Fed’s interest rate control. This occurred in 2019 when the central bank allowed maturing bonds to expire without replacement to reduce holdings, and nearly happened again recently.

After reducing the balance sheet from 2022 forward, the Fed has aggressively purchased Treasury bills since December to restore liquidity during tax season, describing this as a purely technical operation. Market observers widely expect these purchases to slow once May arrives.
