Consider the following information about a banking system: new currency deposited in the system = $40 billion, legal reserve ratio = 0.20, excess reserves prior to the currency deposit = $0. with the $40 billion deposit, the banking system will be able to expand the money supply through loans by
a. $128 billion.
b. $160 billion
c. $200 billion.
d. $40 billion.

c. $200 billion.

Explanation:

In this question, we have to apply the money multiplier formula which is shown below:

Money multiplier =  (1 ÷ legal reserve ratio)

                            = (1 ÷ 0.20)

                            = 5

Now the money supply through loans be computed by

= Money multiplier × new currency deposited amount

= 5 × $40 million

= $200 million

For computing the money lend amount we always considered the money multiplier and the new currency deposited amount

b, fewer problems later! good luck
