Higher Rates Raise Risk of Future Fed Losses

The Federal Reserve’s plans to raise interest rates aggressively to combat high inflation could have an overlooked and uncomfortable side effect for the central bank: capital losses.

The potential for losses hinges on obscure monetary plumbing. The Fed’s $9 trillion portfolio, sometimes called a balance sheet, is full of mostly interest-bearing assets—Treasury and mortgage-backed securities—with an average yield of 2.3%. On the other side of the ledger—the liability side of the Fed’s balance sheet—are bank deposits held at the Fed known as reserves, which are also interest bearing, as well as currency in circulation.
