Final answer:
To contract the money supply, the Fed can increase the discount rate, raise the reserve requirement, and sell short-term U.S. Treasury securities, whereas to expand it, they can decrease the discount rate, lower the reserve requirement, lower interest on reserves, buy short-term U.S. Treasury securities, and use quantitative easing.
Step-by-step explanation:
The Federal Reserve (Fed) can use several tools to either contract or expand the money supply as part of its monetary policy. To contract the money supply, the Fed can:
- increase the discount rate,
- raise the reserve requirement, and
- sell short-term U.S. Treasury securities.
Conversely, to expand the money supply, the Fed may:
- decrease the discount rate,
- lower the reserve requirement,
- lower the interest on reserve balances,
- buy short-term U.S. Treasury securities, and
- engage in quantitative easing (QE) by purchasing long-term government and private mortgage-backed securities.
These actions are meant to influence the interest rate and stimulate
aggregate demand
, which can be necessary during periods of economic downturn, such as the 2008 recession and the COVID-19 pandemic in 2020.
