Suppose a banki ng system has a required reserve ratio of 0.10. How much can the money supply increase in response to a $500 increase in excess reserves for the whole banking system? A. $50. B. $500. C. $5,000. D. $4,500. 7. Suppose a banking system has $120 million in deposits, a required reserve ratio of 20 percent, and total bank reserves for the whole system of $100 million. Then the potential increase in deposit creation for the whole system is equal to A. $120 million. B. $76 million. C. $O D. $380 million. 8. Ceteris paribus, the money supply becomes smaller when A. A loan is repaid to the banking system by a bank customer. B. An individual deposits currency into her transactions account. C. The Federal Reserve reduces the reserve requirement D. A bank uses its excess reserves to make a loan.

Explanation / Answer

5. Required reserve = Total reserves - Excess reserves = 12000 - 2000 = 10000

Deposits = 100,000

Required reserve ratio = Required reserve / Deposits x 100 = 10000/100,000 x 100 = 10%

Multiplier = 1/Required reserve ratio = 1/0.10 = 10

Answer is C) 10

6. Multiplier = 1/RRR = 1/0.10 = 10

Money supply = Excess reserve x Multiplier = 500 x 10 = $ 5000

Answer is C) $ 5000

7. Excess reserve = Total reserve - Required reserve = 100 million - 20% of $ 120 million

= 100 million - 24 million = $ 76 million

Increase in deposit creation = Excess reserve x Multiplier = 76 million x 1/0.20 = 76 million x 5 = $ 380 million

Answer D) $ 380 million

8. A) A loan is repaid to the banking system by a bank customer.
