Feds don’t normally print money. That would be the treasury and they don’t get to choose how much. The feds usually adjust interest rates by buying and selling treasury bonds that they don’t pay for, or I should say pay for with accounts they can adjust their balances as needed, including destroying “money”, to achieve the desired interest rate and slow or speed the economy. A point of interest is that the fed is not a part of the government and isn’t supposed to be influenced by it. I know it’s a lot easier to just say they or the government just print money but there is a lot of nuance. Anyway, that’s not really what the discussion is so have a great day!
