The most important function of a central bank of the country is
to exercise monetary policy. It is the policy to control the money
supply in the economy. The following are the three conventional or
traditional tools of monetary policy used by the Central bank of a
country:
- Open market operations : Central banks control
the money supply by exercising open market operations. In this tool
the central bank sells and buys the securities in the market. It
will purchase securities to increase the money supply in the
economy and it will sell to decrease the money supply.
- Changing reserve requirements : Commercial
banks have to keep a certain portion of their assets in central
bank in the form of cash reserves.CRR facilitate interbank
settlements. Increasing or decreasing CRR is helpful to control
money supply. Raising CRR decreases the money available for banks
to lend to people. This will decrease the money supply in the
economy. Decreasing CRR causes inflation in the economy.
- Changing the discount rate : This tool is also
known as bank rate policy. Bank rate is the rate at which the
commercial banks borrow from central banks. Increasing or
decreasing the bank rate is a tool to control inflation. When the
central bank increases bank rate, it will be costly for a
commercial bank to borrow from central bank. This will
automatically increase the bank's lending rate. This will cause a
decline in the credit creation and thereby the money supply will be
decreased. A decrease in the bank rate causes lending easily and
thereby leads to inflation.
