Since the Global Financial Crisis, the Fed has increased its use of its balance sheet—the ability to hold U.S. Treasury, agency debt and mortgage-backed securities (MBS) — as a means of governing the supply and demand for longer-term interest rates, which generally fall outside the scope of its fed funds rate.
By buying bonds, the Fed aimed to lower long-term interest rates, making borrowing cheaper and stimulating economic activity. This process is known as quantitative easing.
Conversely, by reducing holdings through bonds sales or letting bonds mature the Fed can exert upward pressure on interest rates, or a so-called quantitative tightening of monetary conditions.
A new task force on the balance sheet will evaluate both the size and composition of the Fed’s balance sheet, while providing the banking system with ample reserves. No new announcements were made at the June meeting aside from the task force creation. The Fed’s balance sheet is $6.7 trillion or 21% of nominal GDP – but has declined by $2.2 trillion since June 2022.11
Look for future announcements about the pace of the runoff changing, which may contribute to interest rate volatility.
