Answer:
10%
Step-by-step explanation:
the effects of an expansionary monetary policy are determined by the following formula:
total effect = money injection x money multiplier
- total effect =$100
- money injection = $10
- money multiplier = $100 / $10 = 10
the formula for calculating the money multiplier = 1 / reserve ratio
10 = 1 / reserve ratio
reserve ratio = 1 / 10 = 10%
The required reserve ratio is the fraction of total deposits that banks are required to hold as cash, and cannot lend or invest. This money is to be held by the banks in order for them to have enough money to return to their clients if they want to withdraw their money.
