Why does the fed rarely change the reserve requirement?

The Federal Reserve rarely changes the reserve requirement because it is a blunt tool that can disrupt the banking system and financial markets. Frequent adjustments could lead to uncertainty among banks regarding liquidity management and lending practices. Additionally, the Fed prefers to use more precise tools, such as open market operations and the discount rate, to influence monetary policy and manage economic conditions. Overall, stability and predictability in the banking sector are prioritized to maintain confidence in the financial system.
