The money multiplier is 1/required reserve ratio = 1/0.25 = 4 A $1,000 decrease in excess reserves by the Fed would cause a $4,000 decrease in the money supply based on the money multiplier formula. The answer is c.

47. Summary
47

48. Fractional reserve banking, the
basis of banking today, originated
with the goldsmiths in the Middle
Ages. Because depository institutions
(banks) are not required to keep all
their deposits in vault cash or with the
Federal Reserve, banks create money
by making loans.
48

49. Required reserves are the
minimum balance that the Fed
requires a bank to hold in vault
cash or on deposit with the Fed.
The percentage of deposits that
must be held as required reserves
is called the required reserve ratio.
49

50. Excess reserves exist when a
bank has more reserves than
required. Excess reserves allow a
bank to create money by exchanging
loans for deposits. Money is reduced
when excess reserves are reduced
and loans are repaid.
50

51. The money multiplier is used to
calculate the maximum change
(positive or negative) in checkable
deposits (money supply) due to a
change in excess reserves. As a
formula:
$ multiplier = 1/required reserve ratio.
51

52. Monetary policy is action
taken by the Fed to change the
money supply. The Fed uses three
basic tools: (1) open market
operations, (2) changes in the
discount rate and (3) changes in
the required reserve ratio.
52

53. Open-market operations are the
buying and selling of government
securities by the Fed through its
trading desk at the New York
Federal Reserve Bank. Buying
government securities creates extra
bank reserves and loans, thereby
expanding the money supply.
Selling government securities
reduces bank reserves and loans,
thereby contracting the money
supply. 53

54

55. Changes in the discount rate occur
when the Fed changes the rate of
interest it charges on loans of reserves
to banks. Dropping the discount rate
makes it easier for banks to borrow
reserves from the Fed and expands the
money supply. Raising the discount rate
discourages banks from borrowing
reserves from the Fed and contracts the
money supply.
55

56. Changes in the required reserve
ratio and the size of the money
multiplier are inversely related. Thus, if
the Fed decreases the required reserve
ratio the money multiplier and money
supply increase. If the Fed increases the
required reserve ratio the money
multiplier and money supply decrease.
56

57. Monetary policy limitations include
the following: (1) The money multiplier
can vary. (2) Nonbanks, such as
insurance companies, finance
companies, and Sears, can offer loans
and other financial services not directly
under the Fed’s control. (3) The Fed
might control M1 while the public can
shift funds to M2, M3, or another
money supply definition. (4) Time lags
occur.

59. 1. If a bank has total deposits of $100,000
with $10,000 set aside to meet reserve
requirements of the Fed, its required
reserve ratio is
a. $10,000.
b. 10 percent.
c. 0.1 percent.
d. 1 percent.
B. Required reserve ratio = required
deposits ÷ total deposits x 100 =
$10,000 ÷ $100,000 x 100
59

60. 2. Assume a simplified banking system in which
all banks are subject to a uniform required
reserve ratio of 30 percent and demand
deposits are the only form of money. A bank
that receives a new deposit of $10,000 is able to
extend new loans up to a maximum of
a. $3,000.
b. $7,000.
c. $10,000.
d. $30,000.
B. Excess reserves can be loaned. Excess reserves
= total reserves - required reserves = $10,000 -
(0.3 x $10,000) = $10,000 - $3,000 = $7,000
60

61. 3. The Best National Bank operates with a 10
percent required reserve ratio. One day a
depositor withdraws $400 from his or her
checking account at the bank. As a result, the
bank’s excess reserves
a. fall by $400.
b. fall by $360.
c. fall by $40.
d. rise by $400.
B. Excess reserves = total reserves -
required reserves = -$400 - (0.10 x $400)
= -$400 + $40 = -$360
61

62. 4. If an increase of $100 in excess reserves in
a simplified banking system can lead to a
total expansion in bank deposits of $400,
the required reserve ratio must be
a. 40 percent.
b. 400 percent.
c. 25 percent.
d. 4 percent.
e. 2.5 percent.
C. $ multiplier = ∆ in bank deposits ÷
initial ∆ in excess reserves = 400 ÷ $100
= 4 = 1 ÷ required reserve ratio = 1 ÷
money multiplier x 100.
62

63. 5. In a simplified banking system in which all
banks are subject to a 25% required reserve
ratio, a $1,000 open sale by the Fed would
cause the money supply to
a. increase by $1,000.
b. decrease by $1,000.
c. decrease by $4,000.
d. increase by $4,000.
C. Money supply change (∆ M1) = initial ∆ in
excess reserves x money multiplier (MM).
MM = 1 ÷ required reserve ratio = 1 ÷ 25/100 =
4.
∆ M1 = $1,000 x 4 = -$4,000.
63

64. 6. In a simplified banking system in which all
banks are subject to a 20% required reserve
ratio, a $1,000 open market purchase by the
Fed would cause the money supply to
a. increase by $100.
b. decrease by $200.
c. decrease by $5,000.
d. increase by $5,000.
D. Money supply change (∆ M1) = initial
change in excess reserves x money
multiplier (MM)
MM = 1 ÷ required reserve ratio = 1 ÷ 20/100
=5
∆ M1 = $1,000 x 5 = $5,000.
64

65. 7. The cost to a member bank of borrowing
from the Federal Reserve is measured by the
a. reserve requirement.
b. price of securities in the open market.
c. discount rate.
d. yield on government bonds.
C. The Fed provides a discount window at each
of the Federal Reserve districts banks to
make loans of reserves to banks and change
an interest rate called the discount rate.
