Answer:
True.
Step-by-step explanation:
The federal fund rates, commonly referred to as fed funds rates can be defined as the interest rate at which banks in the U.S lend money to other depository financial institutions, such as credit union or banks, mainly without any collateral and on an overnight basis.
Raising the interest rate on reserves above the current fed funds rate means that the floor of reserve demand will push the equilibrium fed funds rate up along with the interest rate on reserves. Both borrowed reserves and non-borrowed reserves will remain the same.
However, when the Fed reduces the interest rate on reserves below the current fed funds rate, it simply means that, there would be a leftward shift in the demand for reserve line, at any given interest rate. Thus, causing the fed funds rate to decrease, while borrowed reserves and non-borrowed reserves remain unchanged.
