Final answer:
If the reserve ratio decreases from 20 percent to 10 percent, the money multiplier would rise from 5 to 10.
Step-by-step explanation:
The money multiplier is the reciprocal of the reserve requirement. So if the reserve ratio decreases from 20 percent to 10 percent, the money multiplier would rise from 5 to 10.
This means that for every dollar of reserves, the banking system can create $10 of money through loans and deposits.
