# calculation of the value of the simple deposit expansion multiplier

The required reserve ratio is 5%

Assets: Liabilities:

Cash- $24 mil Demand Deposits- $180 mil

Deposits w/ Fed.- $16 mil Time deposits- $10 mil

Loan- $100 mil Capital- $10 mil

Treas. Securities- $60 mil

So I got the following:

Level of reserves is $40 mil.

The reserve ratio is 40/180 or 2/9

The required reserves are $9 mil.

The level of excess reserves are $31 mil.

I got this far, but my last question asks what the value of the simple deposit expansion multiplier is. I think it is 1/0.05 or 20. But then the question asks if the excess reserve goes to 0 then what is the maximum amount by which the money supply can increase is. I have tried to figure it out, but can't. Can you show me how and why,, and if I got the first part correct? This is due tomorrow and I have tried for 2 days to figure it out. I give up!
