Question

Suppose that in a given month $40 million is deposited into the banking system while $50 million is withdrawn. Assume that the reserve requirement is 20 percent and that the banking system had no excess reserves at the beginning of the month. What is the maximum change that can be expected in the money supply as a consequence of these deposits and withdrawals?

 

Instructions: Enter a positive number to show an increase and a negative number to show a decrease.

 

$  million

Answer 1

$40 million was deposited while $50 million was withdrawn.

The net change in the banking system would therefore be,

= 40 - 50

= -$10 million

($10 million ) means that more money left than came in.

The money supply can be calculated as the net change multiplied by the money multiplier.

The Money Multiplier is denoted as a 1/reserve requirement.

Change in Money Supply is,

= -10 million * 1/20%

= -$50 million

Going by the negative number, it means that Money Supply reduces by $50 million.
