Explanation:

Interest rate is one of the monetary policies that can be used to.vonttol the economy.

When interest rate is high cost of borrowing cash from commercial banks will be high so people are discouraged from borrowing. There is higher reserve in banks, and cash flow is restricted.

However in a situation where the economy is troubled the Federal Reserve will reduce interest rate.

This results in cheaper cost of borrowing funds, commercial bank reserves will reduce because of increased outward flow of cash.
