Answer: this tool is powerful and makes it difficult for bank managers to plan for the future and manage funds as they like.
Step-by-step explanation:
Reserve requirements are the amount of money that a bank holds in its reserve to ensure that it can meet liabilities in the case of sudden withdrawals. The reserve requirement is a tool that is used by the central bank of a country to either increase or decrease the money supply in the economy and also influence interest rates.
The changes in reserve requirements to conduct monetary policy is not a good idea for the United States because it is a powerful tool which makes it hard for bank managers to make future plans and manage funds as they want. In a situation whereby small variation in the reserve ratio brings about huge changes in an economy, the changes are positive and okay but in a situation whereby they bring about negative effect, it will be hard to face such scenarios.
