3) The Money Multiplier
• When people deposit money in a bank, the bank does not keep the full value of that deposit
• Instead, it keeps only a fraction and uses the rest for loans
• The portion of deposits that banks keep on hand makes up its reserves

3) The Money Multiplier
• The Federal Reserve sets the reserve ratio– the percentage of deposits banks must
keep readily available– Currently this is 10%
• As banks make loans, those funds are re-deposited, and a portion of them can be loaned out again…and again

3) The Money Multiplier
• This cycle of depositing – loaning – depositing, etc increases the money supply– Remember, M1 includes checking accounts
as well as currency!
• The value of the money multiplier is:M = 1/rr
rr= reserve ratio

• The Federal Reserve uses monetary policy to affect the amount of the money supply, and thus influence economic growth and inflation
• Setting the Reserve Rate– If the Fed increases the reserve rate, the
money supply will go down– If the Fed decreases the reserve rate, the
money supply will go up

The Discount Rate is the interest rate that the Fed charges bank to borrow funds
– Normally set 1% above the federal funds rate, which is the rate at which member banks borrow from each other
– By lowering the discount rate, the Fed can encourage more borrowing and thus increase the money supply

The primary way the Fed influences the money supply, is through open market transactions:
• The Fed buys or sells US Treasury Bonds
• If the Fed buys bonds, the money supply increases
• If the Fed sells bonds, the money supply decreases
