Answer:
1.5%
Explanation:
Reserves is the total amount of a bank's deposit that is not given out as loans Â
Required reserves is the percentage of deposits required of banks to keep as reserves by the central bank Â
Excess reserves is the difference between reserves and required reserves
Total increase in reserve = $15,000,000 + $1,800,000= Â $16,800,000
New excess reserve = total increase in reserve x initial reserve requirement) / initial excess reserve
($16,800,000 x 12.5%) / $15,000,000 = 14%
Increase in reserve requirement = 14% - 12.5% = 1.5%
