Which entity is a central bank?

• A. International Monetary Fund
• B. Bank for International Settlements
• C. Securities and Exchange Commission
• D. Federal Reserve Bank (The Fed)

Answer: (D)

A central bank is the nation's main authority responsible for monetary policy, issuing currency, and maintaining financial stability. The Federal Reserve, commonly called the Fed, is the central bank of the United States, so it fits this role by setting monetary policy, regulating banks, and overseeing payment systems.

The other entities serve different functions. The International Monetary Fund is an international organization that supports global monetary cooperation and financial stability, not a country’s own central bank. The Bank for International Settlements acts as a bank for central banks and supports monetary and financial stability internationally, but it’s not the central bank of a particular country. The Securities and Exchange Commission regulates the securities markets, not monetary policy or the banking system.

So, the Fed is the central bank here because it uniquely holds the national authority over monetary policy and financial supervision in the United States.
