How Banks Create How Banks Create MoneyMoney

Fractional reserve system

•A banking system that provides people immediate access to their deposits but allows banks to hold only a fraction of those deposits in reserve.

5

© 2005 Thomson



The fractional reserve system serves as the basis of all modern banking.

6

© 2005 Thomson



If all depositors lost faith in the banking system and demanded their money back, banks would be unable to meet their demands.

7

© 2005 Thomson



Balance sheet

• The bank’s statement of liabilities (what it owes) and assets (what it owns).

8

© 2005 Thomson



Banks make a profit on the loans they provide, not on their deposits.

9

© 2005 Thomson



Legal reserve requirement

• The percentage of demand deposits banks and other financial intermediaries are required to keep in cash reserves.

10

Cyberspace BankingCyberspace Banking

What is a cyberspace banking?

• Cyberspace is banking conducted over the Internet.

11

• $100,000 + $80,000 = $180,000.

1. Suppose that the banking system initially has $100,000 in demand deposits, and loans out $80,000. Those who borrow this money in turn put it in their demand deposit accounts. How much money is now held in demand deposit accounts?

1. Suppose that the banking system initially has $100,000 in demand deposits, and loans out $80,000. Those who borrow this money in turn put it in their demand deposit accounts. How much money is now held in demand deposit accounts?• Thus fractional reserve banking creates money through loans.

Financial intermediaries

• Firms that accept deposits from savers and use those deposits to make loans to borrowers.

14

© 2005 Thomson



• A fractional reserve system operating within financial intermediaries.

2. What three factors are needed for a banking system to create money?

15

© 2005 Thomson




• People willing to make demand deposits.


16

• People willing to make demand deposits.

• Borrows prepared to take out loans.

17

© 2005 Thomson



Potential money multiplier

• The increase in the money supply that is potentially generated by a change in demand deposits.

18

© 2005 Thomson



3. If the legal reserve requirement is 10 percent, what is the potential money multiplier?• The potential money multiplier “m” = 1/(legal reserve requirement) = 1/0.1 = 10.

19

© 2005 Thomson



• M = ID/LRR.

4. If the legal reserve requirement (LRR) is 25 percent and the initial demand deposit (ID) is $100,000, then what is the maximum potential increase in the money supply (M)?

20

© 2005 Thomson



4. If the legal reserve requirement (LRR) is 25 percent and the initial demand deposit (ID) is $100,000, then what is the maximum potential increase in the money supply (M)?

• M = $100,000/.25 = $400,000.

21

© 2005 Thomson



5. Why might the actual increase in the money supply be less than the maximum potential increase in the money supply?• Because there may not be a sufficient number of borrowers to take advantage of all the available loanable reserves in the banking system.

22

Excess reserves

• The quantity of reserves held by a bank in excess of the legally required amount.

23

© 2005 Thomson



If there is not a sufficient number of borrowers to take advantage of all the available loanable reserves in the banking system, then the banking system will end up holding excess reserves.

24

© 2005 Thomson



• Required reserves are 0.2 × ($100,000) = $20,000.

6. Suppose that a bank holds $100,000 in demand deposits, has a legal reserve requirement of 20 percent, and holds $35,000 in reserves. How much of these reserves are required, and how much are excess?

25

© 2005 Thomson



• Excess reserves = (total reserves) - (required reserves).

6. Suppose that a bank holds $100,000 in demand deposits, has a legal reserve requirement of 20 percent, and holds $35,000 in reserves. How much of these reserves are required, and how much are excess?

6. Suppose that a bank holds $100,000 in demand deposits, has a legal reserve requirement of 20 percent, and holds $35,000 in reserves. How much of these reserves are required, and how much are excess?• Excess reserves = $35,000 - $20,000 = $15,000.

27

© 2005 Thomson



7. How are required reserves recorded on a bank’s balance sheet?• Required reserves are an asset.

28

© 2005 Thomson



8. How are excess reserves recorded on a bank’s balance sheet?• Excess reserves are an asset.

29

© 2005 Thomson



9. How are loans recorded on a bank’s balance sheet?• Loans are an asset.

30

© 2005 Thomson



10. How are demand deposits recorded on a bank’s balance sheet?• Demand deposits are a liability.

31

© 2005 Thomson



• Yes.

11. Suppose that a bank’s assets are made up of required reserves of $10,000, excess reserves of $5,000 and loans of $85,000. If the legal reserve requirement is 10 percent, can we determine how much money the bank holds in demand deposits?

How Banks Create How Banks Create MoneyMoney11. Suppose that a bank’s assets are

made up of required reserves of $10,000, excess reserves of $5,000 and loans of $85,000. If the legal reserve requirement is 10 percent, can we determine how much money the bank holds in demand deposits?• With required reserves of $10,000 and a legal reserve requirement is 10 percent, then demand deposits equal $100,000.

Reversing the Money Reversing the Money Creation ProcessCreation Process

• Some excess reserves that may have otherwise been loaned out will instead be converted to required reserves.

1. What will happen if the Federal Reserve increased the legal reserve requirement for banks?

34

© 2005 Thomson



• Banks with no excess reserves will have to borrow reserves until enough loans are repaid or enough new deposits are made.

1. What will happen if the Federal Reserve increased the legal reserve requirement for banks?

35

© 2005 Thomson



1. What will happen if the Federal Reserve increased the legal reserve requirement for banks?• Either way, increasing the legal reserve requirement will reduce loanable reserves in the banking system, and thus reduce the money supply.

36

© 2005 Thomson



2. What will happen to a bank’s assets if the Federal Reserve increased the legal reserve requirement?

• Required reserves will increase.

37

© 2005 Thomson




• Excess reserves will decrease.

38

© 2005 Thomson




• Loans will decrease.

Why Banks Why Banks Sometimes FailSometimes Fail

1. What will happen if too many borrowers are unable to repay their loans?

• A bank may fail.

40

© 2005 Thomson



2. If a bank fails, what will happen to the depositors?• If deposits are insured by the federal government, then the government will step in and pay depositors up to the maximum insurable amount.

41

© 2005 Thomson



2. If a bank fails, what will happen to the depositors?• If deposits are not insured by the federal government, then depositors may lose their money.

42

© 2005 Thomson



• Fearing that they may lose their money, and having lost confidence in the banking system, some depositors will demand their money back from their deposits.

3. If rumors spread that some borrowers are defaulting on their loans, how will some depositors respond?

43

© 2005 Thomson



• Too many depositors withdrawing their money from their demand deposit accounts will overwhelm the fractional reserve system, and may cause it to fail.


44

© 2005 Thomson



• Many people will lose their money, loanable funds for investment will be eliminated, and a recession may result.


45

© 2005 Thomson



3. If rumors spread that some borrowers are defaulting on their loans, how will some depositors respond?• Prior to modern banking regulation and practices, many recessions were caused by financial panics and banking system failures.

Safeguarding the Safeguarding the SystemSystem

Federal Deposit Insurance Corporation (FDIC)

• A government insurance agency that provides depositors in FDIC-participating banks 100 percent coverage on their first $100,000 of deposits.

47

© 2005 Thomson



Banks participating in the FDIC insurance program must pay insurance premiums in return for FDIC protection.

48

© 2005 Thomson



The FDIC was created in 1933, too late for the tens of thousands of people who had been financially wiped out by bank failures in the Great Depression.

Federal Deposit Federal Deposit Insurance and Moral Insurance and Moral

HazardHazardFully insuring deposits leads to a costly side effect known as moral hazard.

50

© 2005 Thomson



HazardHazardOnce a bank is insured, it has an incentive to take on more risky loans than it otherwise would if it were not insured.

51

© 2005 Thomson



HazardHazardProposed solutions for the moral hazard problem with deposit insurance include:

• Privatize the deposit insurance system

• Reduce the scope of deposit insurance

Yet any change in the deposit insurance system may itself destabilize the banking system.

52

© 2005 Thomson



In addition to deposit insurance, the FDIC also audits banks to make sure that they use sound banking practices.

53

© 2005 Thomson



Despite these safeguards, approximately 10 banks fail each year.

54

© 2005 Thomson



During the 1970s, high farm commodity prices inflated the price of farmland, and high oil prices inflated the value of property in Texas and Oklahoma.

55

© 2005 Thomson



Banks made loans with inflated property values as collateral.

56

© 2005 Thomson


Safeguarding The Safeguarding The SystemSystem

When farm commodity prices and oil prices collapsed in the recession of the early 1980s, many farms and businesses failed, and were unable to repay their loans.

57

© 2005 Thomson



Banks were left holding collateral —land, buildings, and other capital—that was worth less than the amount of the loan.

58

© 2005 Thomson



Consequently, many banks failed, particularly in farm states and in Texas and Oklahoma.

59

© 2005 Thomson



Due to the moral hazard problem, there were questions regarding proper lending practices at some of the failed banks.

Many “thrifts” (savings and loans) in the early 1980s were locked in to long-term mortgage loans that paid the thrifts less than the interest they paid on deposits, causing thrifts to lose money.

70

© 2005 Thomson



This motivated some thrifts to move in to new, more speculative and risky loan markets. Another factor contributing to the failure of so many thrifts was fraudulent lending practices.

71

© 2005 Thomson


Safeguarding the Safeguarding the SystemSystemThe large number of thrift failures in

the 1980s put the Federal Savings and Loan Insurance Corporation (FSLIC) in crisis.

Legislation was passed that created the Resolution Trust Corporation, which handled the disposal of all failed thrifts. The FDIC has assumed the insurance function of the now-defunct FSLIC.
