1. Money and Banks
Chapter 13

2. What Is Money?
Without money, you would have to use barter to get items you want.
Barter is the direct exchange of one good for another, without the use of money.

3. The Money Supply
Anything that serves all of the following purposes can be thought of as money:
Medium of exchange
Store of value
Standard of value

4. The Money Supply
Medium of exchange – Is accepted as payment for goods and services (and debts).

5. The Money Supply Store of value – Can be held for future purchases.
Standard of value – Serves as a measurement for the prices of goods and services.

6. Many Types of “Money”
In colonial America, there were no U.S. dollars so many different things were used as mediums of exchange.
After independence, state-issued paper money acted as money along with gold, silver, or commodities.

7. Many Types of “Money”
The first paper money issued by the federal government was printed in 1861 to finance the Civil War.
The National Banking Act of 1863 gave the federal government permanent authority to issue money.

8. Modern Concepts
Money is anything generally accepted as a medium of exchange.
The “greenbacks” we carry around today are not the only form of “money” we use.
Checking accounts can and do perform the same market functions as cash.

9. Modern Concepts
Credit cards are another popular medium of exchange but are not money.
They are only a payment service with no store of value in and of themselves.

10. Diversity of Bank Accounts
There are many forms of “bank” accounts.
Some bank accounts are better substitutes for cash than others.

11. M1: Cash and Transactions Accounts
Money supply (M1) includes currency in circulation, transaction-account balances, and traveler’s checks.
A transactions account is a bank account that permits direct payment to a third party, for example, with a check.

12. M1: Cash and Transactions Accounts
The distinguishing feature of transaction accounts is that they permit direct payment to a third party (by check or debit card).

13. M2: M1 + Savings Accounts, etc.
M2 money supply – M1 plus balances in most savings accounts and money market mutual funds.
Savings-account balances are almost as good a substitute for cash as transaction-account balances.

14. M2: M1 + Savings Accounts, etc.
How much money is available affects consumers’ ability to purchase goods and, services – aggregate demand.
Aggregate demand is the total quantity of output demanded at alternative price levels in a given time period, ceteris paribus.

15. Composition of the Money Supply
($6,293 billion)
Money market mutual funds and deposits ($1,549 billion)
Savings account balances ($3,408 billion) M1
($1,336 billion)
Traveler’s checks ($8 billion)
Transactions-account balances ($651 billion)
Currency in circulation ($677 billion)

16. Creation of Money
Currency is printed.
Coins are minted.

17. Deposit Creation
When a bank lends someone money, it simply credits that individual’s bank account.
Deposit creation is the creation of transactions deposits by bank lending.

18. Deposit Creation
When a bank makes a loan, it effectively creates money because transactions-account balances are counted as part of the money supply.

19. Deposit Creation There are two basic principles of the money supply:
Transactions-account balances are a large portion of our money supply.
Banks can create transactions-account balances by making loans.

20. Bank Regulation
The deposit-creation activities of banks are regulated by the government.
The Federal Reserve System limits the amount of bank lending, thereby controlling the basic money supply.

21. A Monopoly Bank
When someone deposits cash or coins in a bank, they are changing the composition of the money supply, not its size.

22. A Monopoly Bank
Assume a student deposits $100 from their piggy bank into the monopoly bank and receives a new checking account.

23. The Initial Loan
Monopoly bank loans $100 to Campus Radio station and by crediting its checking account.
Money has been created because checking accounts are money.

24. The Initial Loan Total bank reserves have remained unchanged.
Bank reserves are assets held by a bank to fulfill its deposit obligations.

25. Secondary Deposits
In a one bank system, when Campus Radio uses the loan, the proceeds of the loan are re-deposited in monopoly bank.

26. Fractional Reserves
Bank reserves are only a fraction of total transaction deposits.
The reserve ratio is the ratio of a bank's reserves to its total deposits.

27. Fractional Reserves
The Federal Reserve System requires banks to maintain some minimum reserve ratio.

28. The T-account of the Bank
The books of a bank must always balance, because all of the assets of the bank must belong to someone (its depositors or its owners).

31. Required reserves = minimum reserve ratio X total deposits
Required reserves are the minimum amount of reserves a bank is required to hold by government regulation; Equal to required reserve ratio times transactions deposits.
Required reserves = minimum reserve ratio X total deposits

32. Required Reserves
A minimum reserve requirement directly limits deposit-creation possibilities.

33. A Multibank World In reality, there is more than one bank.
The ability of banks to make loans depends on access to excess reserves.
Example: If a bank is required to hold $20 in reserves but has $100 currently, it can lend out the $80 excess.

34. Excess reserves = Total reserves – Required reserves
Excess reserves are bank reserves in excess of required reserves.
Excess reserves = Total reserves – Required reserves

35. Excess Reserves
Excess reserves are reserves a bank is not required to hold.
So long as a bank has excess reserves, it can make loans.

36. Changes in the Money Supply
The creation of transaction deposits via new loans is the same thing as creating money.

37. More Deposit Creation
As the excess reserves are loaned out again, more deposits are created and thus more money is created.

42. The Money Multiplier
In a multi-bank system, deposits created by one bank invariably end up as reserves in another bank.
This process can theoretically continue until all banks have zero excess reserves (no more loans can be made).

43. The Money Multiplier
The money multiplier is the number of deposit (loan) dollars that the banking system can create from $1 of excess reserves.

44. The Money Multiplier
Required reserves represent leakage from the flow of money, since they cannot be used to create new loans.
Excess reserve can be used for new loans.

45. The Money Multiplier Potential deposit creation =
The money supply can be increased through the process of deposit creation to this limit:
Potential deposit creation =
Excess reserves of banking system
X Money multiplier

46. The Money Multiplier Process
Required reserves
Excess reserves

The public

47. Excess Reserves as Lending Power
Each bank may lend an amount equal to its excess reserves and no more.
The banking system can increase the volume of loans by the amount of excess reserves multiplied by the money multiplier.

48. The Money Multiplier at Work

49. Banks and the Circular Flow
Banks perform two essential functions for the macro economy:
Banks transfer money from savers to spenders by lending funds (reserves) held on deposit.
The banking system creates additional money by making loans in excess of total reserves.

50. Banks and the Circular Flow
By making loans, banks help to transfer income from savers to spenders.
When doing so, banks help maintain any desired rate of aggregate demand.

51. Banks in the Circular Flow
Loans
Factor markets
Product markets
Business firms
Consumers
BANKS
Saving
Investment expenditures
Sales receipts
Wages, dividends, etc.
Income
Domestic consumption

52. Financing Injections The consumer saving is a leakage.
A substantial portion of consumer saving is deposited in banks.
Bank deposits can be used to make loans, which returns purchasing power to the circular flow.

53. Constraints on Deposit Creation
There are three major constraints on deposit creation:
Deposits – Consumers must be willing to use and accept checks rather than cash.
Borrowers – Borrowers must be willing to borrow the money that banks provide.
Regulation – The Federal Reserve sets the ceiling on deposit creation.

54. When Banks Fail
In the past, “runs” of depositors rushing to withdraw their funds have created panics.
Bank closed, wiping out customer deposits, curtailing lending, and often pushing the economy into recession.
In the early part of the Great Depression ( ), 9000 banks failed.

55. Deposit Insurance
The FDIC and FSLIC were created by Congress in , to ensure depositors that their money would be safe -- thus eliminating the motivation for deposit runs.

56. The S & L Crisis
The economic conditions in the 1970s saw many S&Ls stuck earning money on low-interest, long-term loans (mortgages etc.) while having to pay out short-term high-interest fees to their customers.

57. The S & L Crisis
Competition from new financial institutions (e.g. money-market mutual funds) enticed deposits away from S&Ls.
Consequently, many S&Ls failed.

58. Bank Bailouts
S&L failures cost the federal government billions – over $60 billion in 1992 alone – as the FSLIC and FDIC paid off depositors.

59. Bank Bailouts
The Resolution Trust Corporation was created in 1989 to manage the outstanding loans of banks the federal government had to bail out.
