    Monetary Policy

    Monetary policy is generally referred to as either being an expansionary policy, or a contractionary policy.

     

    An expansionary policy increases the total supply of money in the economy and is traditionally used to combat unemployment in a recession by lowering interest rates. Lowered interest rates encourage the household and the firms to increase their consumption and investment respectively. This will shift the AD to the right and result in higher real output and more employment.

    Contractionary policy decreases the total money supply and involves raising interest rates in order to combat inflation. The result will be that investment will fall, and consumption will fall. All of these changes will shift the AD to the left.

    It is argued that an increase in the money supply causes an increase in the rate of inflation. Maintaining a low and stable inflation is one of the main macroeconomic objectives of the Government. Government does so by controlling the supply of money to the economy. This policy is known as monetary policy.

     

    Monetary policy in any country is usually controlled by the Central Bank of that country. The Central bank alters the interest rates in the economy after assessing the inflationary pressures in the market.

    Monetary Policy tools

    Central Bank has three tools of monetary policy:

    Open market operations

    • Open market purchases: The central bank buys government securities to increase the monetary base.
    • Open market sales: The central bank sells government securities to decrease the monetary base.

    Open market operations have a number of advantages:

    • They are under the direct and complete control of the central bank
    • They can be large or small.
    • They can be easily reversed.
    • They can be implemented quickly

    Discount loans

    When a bank receives a discount loan from the central bank, it is said to have received a loan at the “discount window.” The Central  Bank can affect the volume of discount loans by setting the discount rate:

    • A higher discount rate makes discount borrowing less attractive to banks and will therefore reduce the volume of discount loans.
    • A lower discount rate makes discount borrowing more attractive to banks and will therefore increase the volume of discount loans.

     

    Discount lending is most important during ?nancial panics:

    • When depositors lose con?dence in the ?nancial system, they will rush to withdraw their money.
    • This large deposit out?ow puts the banking system in great need of reserves.
    • The central bank stands ready to supply these reserves by making discount loans. In such situations, the central bank acts as a lender of last resort.

    Changes in reserve requirements

    The portion (expressed as a percent) of depositors’ balances banks must have on hand as cash. This is a requirement determined by the country’s central bank. It affects the money multiplier; changes in the required reserve ratio can lead to changes in the money supply. This is also referred to as the “cash reserve ratio” (CRR).

    How money supply works

    Money supply includes all the notes and coins in circulation with the public plus the money with banks. It also includes the deposits in banks and building societies. The later is more significant supply of money and is usually the target of Governments monetary policy. The ways through which Government controls the money supply are:

    Open market operations

    Government usually sells treasury bills and bonds to raise money. Private individuals invest in these bonds and bills in order to get a healthy rate of interest. This reduces the deposits with banks and the money supply.

    Variation of legal reserve requirements

    Usually, the commercial banks have to maintain a certain percentage of their assets as deposit with the Central Bank. When the Central Bank wants to reduce money supply it will increase the limit of the deposit kept by the banks. The commercial banks are left with less money to lend to their customers.

    Central banks

    Central Banks are charged with regulating the size of a nation’s money supply, the availability and cost of credit, and the foreign-exchange value of its currency. Regulation of the availability and cost of credit may be designed to influence the distribution of credit among competing uses. The principal objectives of a modern central bank in carrying out these functions are to maintain monetary and credit conditions conducive to a high level of employment and production, a reasonably stable level of domestic prices, and an adequate level of international reserves.

    Function of a Central Bank

    A central bank usually carries out the following responsibilities:

    • Implementation of monetary policy.
    • Controls the nation’s entire money supply.
    • The Government’s banker and the bankers’ bank (“Lender of Last Resort”).
    • Manages the country’s foreign exchange and gold reserves and the Government’s stock register;
    • Regulation and supervision of the banking industry
    • Setting the official interest rates- used to manage both inflation and the country’s exchange rate – and ensuring that this rate takes effect via a variety of policy mechanisms
