The Fed (a.k.a. the monetary authority) has two primary tools: the interest rate

The Fed (a.k.a. the monetary authority) has two primary tools: the interest rate on reserves and purchases of securities. Using data from Fred, chart both since 2008. For the purchases, use “Assets: Securities Held Outright”. For rates, use “Interest Rate on Required Reserves” up to 2021 and then “Interest Rate on Reserve Balances” after that.
Finally, note that interest rates are in percent and purchases are in dollars, so you will need assign them to different axes. DO AN EXCEL OF THESE INSTRUCTIONS WORKING WITH FEDERAL RESERVE WEB
