Open Market Operations Explained

Open market operations are the primary tool central banks use to manage the money supply and influence interest rates.

This process involves the central bank actively buying or selling government securities (like bonds) in the open market.

• Buying Securities: When the central bank buys securities, it injects money into the banking system, increasing the money supply and typically lowering interest rates. Banks have more reserves available to lend.
• Selling Securities: When the central bank sells securities, it withdraws money from the banking system, decreasing the money supply and typically raising interest rates. Banks have fewer reserves available.

Why Other Options Are Incorrect

• International market operations relate to foreign exchange markets and currency exchange rates, not domestic money supply management through securities.
• National market operations is a vague term; "open market operations" is the specific and standard terminology for the described actions.
• Closed market operations is not a recognized term for this type of central bank policy.

Therefore, the actions described align precisely with the definition of open market operations.
