Shrinking the Fed's Balance Sheet Proves Easier Said Than Done

Stanford Institute for Economic Policy Research (SIEPR) experts warn that shrinking the Federal Reserve's balance sheet is easier said than done. With a current size of $6.7 trillion, reducing it will require careful planning and consideration.

The Fed's balance sheet grew significantly during the 2008 financial crisis as part of quantitative easing efforts. Since then, it has continued to expand, peaking at $8.9 trillion in 2022. To reduce its size, the Fed would need to unload some of these assets by creating more reserve balances.

However, Darrell Duffie, an emeritus professor of finance at Stanford Graduate School of Business and senior fellow at SIEPR, notes that banks have become accustomed to holding large reserves. In fact, he calls this phenomenon the 'ratchet effect.' Banks prefer holding extra reserves because they pay interest, making it unattractive for them to return excess balances to the Fed.

While there is no consensus on how much of its reserve balances the Fed could realistically unload, Duffie emphasizes that further research is needed. One potential solution is tiered remuneration, where the Fed would offer a lower interest rate for reserves above a certain threshold. This could incentivize banks to reduce their excess holdings.
