Answer:
Excess reserve = $180 million
Explanation:
Required-reserve ratio: The minimum percentage that banks are required to keep as reserve is known as the required-reserve ratio. In this question, it is given as 10%. Multiply this ratio by the total deposit and you will get the required reserve in dollar amount.
Therefore the required reserve for this bank = 10% ×$200 million= $20 million
Excess reserve; Excess reserve is the balance of the total deposit over and above the required reserve. The bank can lend and create loan asset from this balance.
It is calculated as = Total deposit - Required reserve
So we apply this to our question
Excess reserve = $200 million - (10% × $200 million) = 180 million
Excess reserve = $180 million
