Credit Creation Total ?
$ 1 Required reserve ratio Bank multiplier = Bank Calculation of Credit Creation Total deposit increment = initial deposit x banking multiplier
$ Bank
Remember ? • Required reserve ratio (RRR) =25% • Jack put $200 into the bank as an initial demand deposit
1 Required reserve ratio 1 25% Bank multiplier = = = 4
Total deposit increment = initial deposit x banking multiplier Total deposit increment = $200 x 4 =$800 The maximum amount of deposit created is $800
$200 RRR=25% Multiplier = 4 Bank $800
