Open Market Operations

What is Open Market Operations?

An Open Market Operation or OMO is merely an activity performed by the central bank to either give or take liquidity to a financial institution or a group of financial institutions and the aim of OMO is not only to strengthen the liquidity status of the commercial banks but also to take surplus liquidity from them.

Steps of Open Market Operations

The central bank takes either of the following two main steps based on the economic conditions which are known as Open market operations:

1. Buying government bonds from banks
2. Selling government bonds to banks

Let us discuss each step of open market operations in detail:

  1. Buying Government Bonds from Bank

    When the central bank of the Country buys government bonds the economy is usually in the recessionary gap phase with unemployment being a big problem.

    When the central bank buys government bonds it increases the money supply in the economy. The increased money supply decreases interest rates. The decreased interest rates cause consumption and investment spending to increase and hence the aggregate demand rises. Increased aggregate demand causes real GDP to increase.

    Thus, buying government bonds from Banks increases the real GDP of the economy hence this method is also called Expansionary Monetary policy.

  2. Selling Government Bonds to Banks

    The central banks sell government bonds to banks when the economy is facing inflation. The central bank tries to control inflation by selling government bonds to banks.

    When government bonds are sold by the central bank, it sucks the excess money from the economy. This causes a decrease in the money supply. A decreased money supply causes interest rates to increase. An increased interest rate causes consumption and investment spending to fall and thus aggregate demand falls. The decrease in aggregate demand causes real GDP to fall.
    Thus, selling government bonds to Banks decreases the real GDP of the economy hence this method is also called Contractionary Monetary policy.

When the central bank offers securities and government bonds to other banks and the public it affects the supply and demand of credit as well.
  • The buyers of the bonds deposit the money from their account to the central bank’s account thereby decreasing their own reserves. With the commercial banks buying such securities they will have less money to lend to the general public thus reducing their credit creation capacity. Thereby, impacting the supply of credit.
  • When the central bank sells the securities, there is a decrease in the price of the bonds and since bond prices and interest rates are inversely related, the interest rates rise. As the interest rates rise, there is a decrease in demand of credit.
  • With the decrease in supply and demand for credit due to fewer reserves and high-interest rates, consumption reduces thus reducing inflation.
  • When the central bank buys the securities the cycle is reversed, inflation rises and interest rates decrease.

#2 – Money Supply Targeting

  • The central bank may target and control the money supply in the economy. The central bank tries to maintain adequate liquidity in the banking system when it feels there is high liquidity it tries to suck the excess liquidity by selling bonds and vice-versa.
  • Eg. Reserve Bank of India conducted two Open market Operations (OMO) purchase auctions of Rs 10000 crores each on June 21, 2018, and July 19, 2018, to maintain durable liquidity.
  • This may be done to check the value of the currency with respect to fiat currencies and other foreign currencies.
