Fed Balance Sheet Shrinkage: Easier Said Than Done

Shrinking the Federal Reserve's balance sheet is a complex task, as highlighted by Stanford Graduate School of Business Professor Darrell Duffie in his recent paper. The Fed's balance sheet has grown significantly since the 2008 financial crisis, reaching $6.7 trillion today from $900 billion two decades ago.

The growth is largely due to quantitative easing, where the Fed bought up bonds to stabilize the economy. As a result, the Fed created more reserve balances, which are deposits held at the Fed by commercial banks. However, this has led to concerns that the Fed's large balance sheet may be perceived as supporting the government's fiscal policies.

Duffie emphasizes that the Fed's primary goal is to set interest rates and control inflation, not provide fiscal support. Nevertheless, a big balance sheet can impair the Fed's independence and lead to political pressure to control it more closely.
