Explanation:

An open market operation (OMO) is an operation by a central bank to give lquidity to a bank or receive liquidity in its currency from a bank. A central bank uses OMO as the major means of balancing monetary policy target in terms of inflation, interest rates, or exchange rates, by purchasing or selling of government securities so as to to expand or contract money in the bank system and control interest rates.
