Answer: $500 million
Explanation:
The required reserve ratio is the fraction of the total deposit that a bank recieves which is mandated by the central bank to be kept and should not be given out.
If the entire banking system has $50 million in excess reserves and a required reserve ratio of 10 percent. The deposit-creation potential of the banking system will be:
= $50million/10%
= $50million/0.1
= $500 million
