Answer and Explanation:
The computation is shown below
As we know that
The increase in money supply is
Increase in money supply = (1 ÷ Required reserve ratio) × Excess reserve.
Since the required reserve ratio is 10%
And, the deposit is $5 million
So, the required reserve is
= $5 million × 0.10
= $500,000
Also
Total reserve = required reserve + excess reserve
where,
Total Reserve = $5,000,000
And required reserve = $500,000.
So, Excess reserve is
= $5,000,000 - $500,000
= $4,500,000
Now, Increase in money supply is
= (1 ÷ 0.10) × $4,500,000
= $4.5 million
So it would rise directly by $4.5 million and have an extra lending capacity of $4.5 million that would be created for the banking system
