Money & Banking
Chapter 17
2008 Q 8
• Explain with the aid of an example,
how it is possible for banks to create
credit.
• Mr X lodges €100 into the bank
• The bank knows from experience that
only 10% of this money is ever
demanded in cash.
• So if it keeps €10 in the bank it can
lend out the other €90 (=10x9).
• Banks are not happy to do just this.
• They want more!!!
• If they keep the full €100 cash in
the bank then they can get away with
lending €900 (= 100X9).
• Where does this €900 come from?
• They generate €900 by allowing
customers to open overdraft a/c’s.
• Customers then write cheques.
• These cheques will eventually be
lodged in the bank as deposits.
• The bank now has deposits of €1,000.
• But still only has €100 cash which is
all it needs as only 10% will be
demanded!
• No cash changes hands in these
transactions.
• Credit has been created based on the
Primary Liquidity Ratio (PLR).
Primary Liquidity Ratio
• The amount of loans a bank gives out
is related to, but in excess of their
cash deposits and is based on their
reserve ratio.
• It is written as a percentage.
Formula
Reserve Ratio/PLR = Cash
X 100
Total Deposits
€100
€1,000
Reserve Ratio/PLR = 10 %
X 100
Increase in the
Money Supply
(increase in cash reserves x 1 ) – inc in cash reserves
reserve ratio
( €100
x 1 ) - €100
.10
€900
Note
• The lower the PLR the more money
the banks can create.
• The higher the PLR the less money
the banks can create.

turned into cash eg. shares) held by
the banks to claims on the bank.
