How does it depend on the reserve ratio? Negatively or positively? c) Suppose that the Fed injects \$80 billion of new reserves into the banking system.

Loans are equal to \$800 million, required reserves are \$40 million, rr = 10%.
a) If the bank does not hold excess reserves, then its assets are \$800 million, liabilities are 40/0.1 = \$400 million, capital is \$400 million.
b) Money multiplier can be calculated using formula mm = 1/rr = 1/0.1 = 10. Money multiplier has inverse (negative) relationship with the reserve ratio.
c) If the Fed injects \$80 billion of new reserves into the banking system, then the total change in money supply in the whole banking system will be 80/0.1 = \$800 billion.
