Suppose the Bank of Canada buys $5 million worth of government
securities from CBA,
a commercial bank.
a) Using T-account analysis, show what happens to the balance
sheets of the BoC and
CBA immediately.
b) If CBA does not want to hold any excess reserves, it will make
more loans. Show the
change for its balance sheet reflecting this lending.
c) Using T-account analysis, show what happens to the balance sheet
of the CBA when the
borrower withdraws cash from CBA
d) What is the net change for the balance sheet of CBA after the
withdrawal? Show the T-
account.
e)Use the following notation: C is currency in circulation
outside banks, R is bank reserves, D is deposits, L is loans, MB is
the monetary base, M is
total money supply, r is the required reserve ratio, and c is the
currency-to-deposit ratio.
Assume c = 0.05 and r = 0.2. Suppose all commercial banks hold zero
excess reserves.
Following the $5 million open market purchase, what will be the
change of C, R, D, L, MB
and M after the money supply process is completed? Calculate:
m = ________________________
∆C = _______________________
∆R = _______________________
∆D = _______________________
∆L = _______________________
∆MB = _____________________
∆M =______________________
a)
The purchase of $5 million by BoC increases its asset by $5 million, at the same time it has to pay CBA by increasing the reserve of the bank. This increases the liability of the BoC by the amount of reserve.
The transaction decreases securities and increases reserve by $5 million on the asset side.
