Types of Open Market Operations

Disadvantages of Discount Lending
1. Creating confusion about the intentions of the central bank through the announcement of discount rate changes.

2) increases the demand for reserves,
3) increases the interbank rate, and
4) reduces the money supply.
It affects all banks equally and has a powerful effect on money supply.
Disadvantages of Reserve Requirements
1. Not practical because small changes in required reserve ratio leads to large changes in money supply, making mistakes too costly.
2. Raising reserve requirements may cause liquidity problems for banks with low excess reserves.
