The central bank uses three main tools to control the money supply and influence interest rates: open market operations, reserve requirements, and the discount rate. These tools allow the central bank to inject or remove money from the economy, affecting lending and borrowing.
Understanding these tools is crucial for grasping how monetary policy works. Open market operations involve buying and selling securities, reserve requirements control bank lending, and the discount rate affects borrowing costs. These tools work together to shape the economy's financial landscape.
Monetary Policy Tools
Open Market Operations
- Involve the buying and selling of government securities by the central bank

Reserve Requirements
- Minimum amount of reserves banks must hold against their deposits

Discount Rate
- Interest rate at which the central bank lends money to commercial banks

- Higher reserve requirements reduce the money multiplier
- Limits the amount of money banks can lend
- Reduces the money supply
- Lower reserve requirements increase the money multiplier
- Allows banks to lend more money

Reserve Requirements for Money Control
Lending Capacity
- Reserve requirements determine the amount of money banks can lend out
- Based on the deposits banks hold
- Higher requirements limit lending capacity
- Reduces the money supply
- Puts upward pressure on interest rates
- Lower requirements increase lending capacity
- Increases the money supply
- Puts downward pressure on interest rates
Banking System Stability
- Reserve requirements help maintain stability in the banking system
- Ensure banks have sufficient reserves to meet withdrawal demands
- Prevent excessive lending that could lead to financial instability
- Act as a buffer against bank runs and liquidity crises
Discount Rate: Purpose and Impact
Monetary Policy Signaling
- Discount rate serves as a signal of the central bank's monetary policy stance
- Changes in the discount rate can influence market expectations
- Higher rate signals tighter monetary policy
- Lower rate signals looser monetary policy
- Can affect the spread between the discount rate and other market interest rates
- Influences banks' willingness to lend
Last Resort Lending
