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
How Banks Create How Banks Create MoneyMoney
The fractional reserve system serves as the basis of all modern banking.
6
How Banks Create How Banks Create MoneyMoney
If all depositors lost faith in the banking system and demanded their money back, banks would be unable to meet their demands.

Balance sheet
The bank’s statement of liabilities (what it owes) and assets (what it owns).
8

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

What is a virtual bank?
• Virtual banks, or cyberbanks, only exist on the Internet.

How Banks Create How Banks Create MoneyMoney
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?
• $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?
• Thus fractional reserve banking creates money through loans.

Potential money multiplier
The increase in the money supply that is potentially generated by a change in demand deposits.
18
How Banks Create How Banks Create MoneyMoney
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
How Banks Create How Banks Create MoneyMoney
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 = ID/LRR.
20
How Banks Create How Banks Create MoneyMoney
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
How Banks Create How Banks Create MoneyMoney
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
How Banks Create How Banks Create MoneyMoney
Excess reserves
The quantity of reserves held by a bank in excess of the legally required amount.
23
How Banks Create How Banks Create MoneyMoney
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.

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?
• 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?
• 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?
• Excess reserves = $35,000 - $20,000 = $15,000.
27

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

How Banks Create How Banks Create MoneyMoney
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?
• Yes.

1. What will happen if the Federal Reserve increased the legal reserve requirement for banks?
• Some excess reserves that may have otherwise been loaned out will instead be converted to required reserves.
34
Reversing the Money Reversing the Money Creation ProcessCreation Process
1. What will happen if the Federal Reserve increased the legal reserve requirement for banks?
• Banks with no excess reserves will have to borrow reserves until enough loans are repaid or enough new deposits are made.
35

1. What will happen if too many borrowers are unable to repay their loans?
• A bank may fail.

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.

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
Why Banks Why Banks Sometimes FailSometimes Fail
3. If rumors spread that some borrowers are defaulting on their loans, how will some depositors respond?
• 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.
43
Why Banks Why Banks Sometimes FailSometimes Fail
3. If rumors spread that some borrowers are defaulting on their loans, how will some depositors respond?
• Too many depositors withdrawing their money from their demand deposit accounts will overwhelm the fractional reserve system, and may cause it to fail.
44

3. If rumors spread that some borrowers are defaulting on their loans, how will some depositors respond?
• Many people will lose their money, loanable funds for investment will be eliminated, and a recession may result.

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
Safeguarding The Safeguarding The SystemSystem
Banks participating in the FDIC insurance program must pay insurance premiums in return for FDIC protection.
48
Safeguarding The Safeguarding The SystemSystem
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.

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
Federal Deposit Federal Deposit Insurance and Moral Insurance and Moral
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
Safeguarding The Safeguarding The SystemSystem
In addition to deposit insurance, the FDIC also audits banks to make sure that they use sound banking practices.
53
Safeguarding The Safeguarding The SystemSystem
Despite these safeguards, approximately 10 banks fail each year.
54
Safeguarding The Safeguarding The SystemSystem
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
Safeguarding The Safeguarding The SystemSystem
Banks made loans with inflated property values as collateral.
56
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
Safeguarding The Safeguarding The SystemSystem
Banks were left holding collateral—land, buildings, and other capital—that was worth less than the amount of the loan.
58
Safeguarding The Safeguarding The SystemSystem
Consequently, many banks failed, particularly in farm states and in Texas and Oklahoma.
59
Safeguarding The Safeguarding The SystemSystem
Due to the moral hazard problem, there were questions regarding proper lending practices at some of the failed banks.

Safeguarding The Safeguarding The SystemSystem
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
Safeguarding The Safeguarding The SystemSystem
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
Safeguarding The Safeguarding The SystemSystem
The large number of thrift failures in the 1980s put the Federal Savings and Loan Insurance Corporation (FSLIC) in crisis.
72
Safeguarding The Safeguarding The SystemSystem
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.
