Banks and the Money Supply: An Example: NO BANKING SYSTEM
Public holds the $100 as currency.
Money supply = $100.
100% RESERVE BANKING SYSTEM
PUBLIC DEPOSITS $100 IN BANK, BANK HOLDS 100% OF THE DEPOSIT AS RESERVES: MONEY SUPPLY = CURRENCY +DEPOSITS. reserves are listed as $100 and deposits are listed as $100
MONEY SUPPLY= currency + deposits
= currency + deposits
Fractional reserve banking system
suppose R is 10% . bank loans all BUT 10% of deposit: reserves are $10, loans are $90 and deposits are $100. so they make money by using the money supply formula : currency + deposits = 90+100= 190!
how does money grow in a fractional reserve banking system?
creates money, but not wealth. the borrower gets $ in currency and now they have $90 in debt
the money multiplier
the amount of money the banking system generates with each dollar of reserves The money multiplier equals 1/R. In our example, R = 10% money multiplier = 1/R = 10 $100 of reserves creates $1000 of money
required reserves
m (required reserve ratio) * demand deposit
