We are asked to solve for the excess reserves. There are given values such as:
Checkable deposits = $ 150,000,000
Total reserves = $12,000,000
Required reserve ratio = 8%
Solving for reserve amount, we have:
Reserve amount = 0.08 * $150,000,000 = $ 12,000,000
Solving for the excess:
Excess reserves = $ 12,000,000 - $12,000,000 = $0
The answer is $0.
