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. LO1

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 LO1

4 The Money Supply Medium of exchange – Is accepted as payment for goods and services (and debts). LO1

5 The Money Supply Store of value – Can be held for future purchases. Standard of value – Serves as a yardstick for measuring the prices of goods and services. LO1

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. LO1

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. LO1

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. LO1

9 Modern Concepts Credit cards and online mechanisms 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. LO1

10 Diversity of Bank Accounts There are many forms of “bank” accounts. Some bank accounts are better substitutes for cash than others. LO1

11 M1: Cash and Transactions Accounts Money supply (M1) includes currency in circulation, transaction- account balances, and traveler’s checks. LO1

12 M1: Cash and Transactions Accounts A transactions account is a bank account that permits direct payment to a third party, for example, with a check. The distinguishing feature of transaction accounts is that they permit direct payment to a third party (by check or debit card). LO1

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. LO1

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. LO1

15 Composition of the Money Supply Currency in circulation ($750 billion) Transactions-account balances ($603 billion) Savings account balances ($4,926 billion) Money market mutual funds and deposits ( $827 billion) Traveler’s checks ($7 billion) M2 ($7,113 billion) M1 ($1,360 billion) LO1

16 Creation of Money Currency is printed. Coins are minted. Where do transaction accounts come from?

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. LO2

18 Deposit Creation When a bank makes a loan, it creates money because transactions- account balances are counted as part of the money supply. LO2

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. LO2

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. LO2

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. LO2

22 A Monopoly Bank Assume a student deposits $100 from their piggy bank into the monopoly bank and receives a new checking account. LO2

23 T Accounts T accounts are used to keep track of changes in reserves, deposit balances, and loans. 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). LO2

24 T Accounts Assets are things the bank owns or is owed by others. Includes cash held in a bank’s vaults, IOUs (loan obligations) from bank customers, reserve credits at the Federal Reserve, and securities (bonds) purchased by the bank. LO2

25 T Accounts Liabilities are things the bank owes to others. A bank’s largest liabilities are its customers’ deposits because deposits are owed to its customers “on demand.” LO2

27 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. LO2

28 The Initial Loan Total bank reserves have remained unchanged. Bank reserves are assets held by a bank to fulfill its deposit obligations. LO2

30 Secondary Deposits In a one bank system, when Campus Radio uses the loan, the proceeds of the loan are re-deposited in monopoly bank. LO2

31 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. LO2

32 Fractional Reserves The Federal Reserve System requires banks to maintain some minimum reserve ratio. LO2

33 Required Reserves Required reserves are the minimum amount of reserves a bank is required to hold by government regulation. Equals the required reserve ratio times transactions deposits. Required reserves = minimum reserve ratio X total deposits LO2

34 Required Reserves A minimum reserve requirement directly limits deposit-creation lending possibilities. LO2

35 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 has $100 in reserves and is required to hold $20, it can lend out excess reserves of $80. LO2

36 Excess Reserves Excess reserves are bank reserves in excess of required reserves. Excess reserves = Total reserves – Required reserves LO2

37 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. LO2

38 Changes in the Money Supply The creation of transaction deposits via new loans is the same thing as creating money. LO3

39 More Deposit Creation As the excess reserves are loaned out again, more deposits are created and thus more money is created. LO3

44 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). LO3

45 The Money Multiplier The money multiplier is the number of deposit (loan) dollars that the banking system can create from $1 of excess reserves. LO3

46 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. LO3

47 The Money Multiplier 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 LO3

48 The Money Multiplier Process Required reserves Excess reserves Leakage into The public LO3

49 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. LO3

50 The Money Multiplier at Work LO3

51 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.

52 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.

53 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

54 Financing Injections The consumer saving is a leakage. A substantial portion of consumer saving is deposited in banks.

55 Financing Injections Bank deposits can be used to make loans, which returns purchasing power to the circular flow. The banking system can create any desired level of money supply if allowed to expand or reduce loan activity at will.

56 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.

57 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.

58 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.

59 The S & L Crisis In the 1970s many S&Ls were stuck earning money on low-interest, long- term loans while having to pay out short-term high-interest fees to their customers.

60 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.

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

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