If the required reserve ratio is 100 percent, could the Federal Reserve still change the
money supply with open market operations? Explain whether they could or could not.
Suppose you deposit $4,000 in currency into your checking account at Bank of America.
Assume that Bank of America has no excess reserves at the time you make your deposit and
that the required reserve ratio is 10 percent.
a. Use a T–account to show the initial effect of this transaction on Bank of America’s
balance sheet.
b. Suppose that Bank of America makes the maximum loan they can from the funds you
deposited. Use a T–account to show the initial effect on Bank of America’s balance sheet
from granting the loan. Also include in this T–account the transaction from question (a.).
c. Now suppose that whoever took out the loan in question (b) writes a check for this
amount and that the person receiving the check deposits it in Bank of Boston. Show the
effect of these transactions on the balance sheet of Bank of America and Bank of Boston,
after the check has been cleared. On the T–account for Bank of America, include the
transactions from questions (a) and (b).
d. What is the maximum increase in checking account deposits that can result from your
$4,000 deposit? What is the maximum increase in the money supply? Explain.
