Which organization is responsible for regulating the money supply in the United States?

• A. World Bank
• B. IMF
• C. Federal Reserve System
• D. Securities and Exchange Commission

Answer: (C)

Regulating the money supply is a function of a country’s central bank through monetary policy. In the United States, that role belongs to the Federal Reserve System. The Fed influences how much money is circulating and how easily banks can lend by using tools like open market operations (buying or selling government securities to change bank reserves), adjusting the discount rate (the interest rate charged to banks for borrowing from the Fed), and setting reserve requirements (how much banks must hold in reserve). By expanding or tightening these controls, the Fed aims to keep prices stable, support employment, and promote healthy economic growth.

The other organizations have different roles. The World Bank and IMF are international institutions that assist countries with financial stability and development, not the U.S. money supply. The Securities and Exchange Commission governs the securities markets and protects investors, not monetary policy.
