Reserve ratio is the ratio of balance held as cash to the depositors' balances. In other words,
Reserve ratio = Cash held as cash/Dopsits
In the current senario;
Deposits = $100,000
Actual reserve = $15,000
For 20% required reserve ratio,
Reserve required = 20/100*100,000 = $20,000. Therefore money creating potential = Actual reserve-Required reserve = 15000-20000 = -$5,000
For 14% required reserve ration,
Reserve required = 14/100*100000 = $14,000. And money-creating potential = 15,000 - 14,000 = $1,000.
The correct answer is the first option: -$5,000; $1,000
