  1. Fractional Reserve Banking

  2. Fractional Reserve Banking • When you put $100 in the bank. All of your money does not have to stay in the bank. • Some is kept in RESERVE (kept in the bank’s vault). • The rest of it can be loaned out. Banks make money by investing your dollars somewhere else.

  3. Fractional Reserve Banking • Reserves= Any money that has been deposited in a bank, but not loaned out yet. • Required Reserves (required ratio)= the percentage of money banks are required by law to keep in reserves • Fractional-Reserve Banking= A banking system where banks only must hold a fraction of all deposits in reserve

  4. Assets vs. Liabilities • Assets- What the bank owns • Liabilities- What a bank owes

  5. First Bank of Econville • Let’s pretend that you deposit $100 into the First Bank of Econville. • The required ratio is 10% (.10 as a fraction) • You would see the following statement for the bank.

  6. Second Bank of Worchester • First Bank of Econville deposits $90 into the Second Bank of Worchester. • The SBoW now must keep some in reserve (10%) and can loan out the rest. • We have now created money that did not exist. • WHAAAAAAAATTT?????

  7. Money Creation • The only money that ACTUALLY exists is the first $100 you deposited in the 1BoE. The rest of the money was created. The 1BoE created $90 and the SBoW created another $81. • This can continue on until banks are loaning each other just pennies. • But there is an easier way to do find out just how much money has been created…the multiplier

  8. Multiplier • The Money Multiplier- the amount of money that the banking system can create given an initial deposit • The Fed uses the Money Multiplier to prescribe exact Monetary Policy actions and changes in the money supply.

  9. Money Multiplier • M=1/R • M-money multiplier • R- reserve ratio • In our problem from before, the reserve ratio was 10%. • M= • M=

  10. Money Supply IncreaseMoney Created • From our initial deposit of $100, using the multiplier, we can conclude that the increase in the money supply was $________________________ • And therefore, $____________ was created from the initial increase in reserves
