Which of the following is a monetary policy tool related to bank reserves?

• A. Reserve rate
• B. Discount rate
• C. Open market operations
• D. Tax policy

Answer: (A)

Monetary policy uses tools that directly influence how many reserves banks must hold and how easily they can lend. The reserve requirement (often called the reserve ratio) is a direct tool for this purpose: it sets the fraction of deposits that banks must hold as reserves. Raising this requirement reduces the funds banks can lend and contracts the money supply, while lowering it frees up more reserves for lending and can expand credit. The discount rate is the interest rate charged by the central bank on loans to banks, which affects borrowing costs more than the overall level of reserves. Open market operations change the amount of reserves by buying or selling government securities, shifting liquidity in the banking system. Tax policy is fiscal policy, not a monetary tool. So, the option describing the reserve requirement directly ties to bank reserves, making it the best choice.
