Chapter 15: Problem 18

Explain how to use an open market operation to expand the money supply.

Short Answer

Expert verified

To expand the money supply using open market operations, the central bank (e.g., the Federal Reserve) buys government securities from financial institutions in the open market. This action injects money into the economy and increases the reserve accounts of the institutions, allowing them to make more loans, which further increases the money supply. As a result, interest rates decrease due to the increased availability of money, leading to increased borrowing, spending, and investment activities, ultimately stimulating economic growth and affecting inflation levels.

Step by step solution

Define Open Market Operations

Open market operations (OMO) are the buying and selling of government securities in the open market by the central bank (such as the Federal Reserve in the United States) to control the money supply in the economy. The main objective of OMO is to achieve desired interest rates, control inflation, and stabilize the financial system.

Explain the Role of the Central Bank

The central bank conducts open market operations by buying and selling government securities such as Treasury bonds, notes, and bills. By doing so, the central bank (or the Federal Reserve) has direct influence over the amount of money circulating in the economy and can achieve desired interest rates and target levels of inflation.

Expanding the Money Supply through Open Market Operations

To expand the money supply, the central bank will buy government securities (bonds, notes, or bills) from financial institutions such as banks and other market participants in the open market. By buying these securities, the central bank injects money into the economy, increasing the money supply.

Describe the Mechanism of Increasing Bank Reserves

When the central bank purchases government securities, it pays for them by crediting the reserve accounts of the financial institutions, thus increasing their reserves. These higher reserves allow banks to make more loans and increase the money supply further as the borrowing and spending activities of businesses and consumers expand.

Illustrate the Impact of Expanding the Money Supply

As the central bank continues to purchase government securities, the money supply in the economy expands, leading to a decrease in interest rates due to the increased availability of money. Lower interest rates make borrowing cheaper and more attractive, leading to increased spending, investment, and lending activities, which can stimulate economic growth and eventually affect the level of inflation.
