Money and Banks
• Money affects not only morals and ideals but also the way an economy works– What is money? – How is money created?– What role do banks play in the circular flow of
income and spending?
![Page 3: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/3.jpg)
13-3
What Is Money?
• Without money, you would have to use barter to get items you want
• Barter: The direct exchange of one good for another, without the use of money
• Acquiring goods and services would be much more difficult and time-consuming
![Page 4: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/4.jpg)
13-4
The Money Supply
• Anything that serves the following purposes can be thought of as money:– Medium of exchange: Is accepted as payment for
goods and services (and debts)– Store of value: Can be held for future purchases– Standard of value: Serves as a yardstick for
measuring the prices of goods and services
![Page 5: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/5.jpg)
13-5
Many Types of “Money”
• In colonial America, many different things were used as mediums of exchange
• After independence, it was state-issued paper money and gold, silver, and commodities
• The National Banking Act of 1863 gave the federal government permanent authority to issue money
![Page 6: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/6.jpg)
13-6
Modern Concepts
• Money: Anything generally accepted as a medium of exchange
• Checking accounts can and do perform the same market functions as cash
• Credit cards and online methods are popular mediums of exchange but are not money
![Page 7: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/7.jpg)
13-7
Diversity of Bank Accounts
• There are many forms of “bank” accounts
• Some are better substitutes for cash than others– Regular checking accounts are used all the time to
pay bills or make purchases– Consumers can’t write checks on most savings
accounts or use CDs to make purchases
![Page 8: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/8.jpg)
13-8
M1: Cash and Transactions Accounts
• Money supply: (M1) Currency held by the public, plus balances in transactions accounts
• M1 includes– Currency in circulation– Transactions account balances– Traveler’s checks
![Page 9: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/9.jpg)
13-9
M1: Cash and Transactions Accounts
• Transactions accounts are the readiest substitutes for cash in market transactions
• Transactions account: A bank account that permits direct payment to a third party– Do not require a trip to the bank to make a special
withdrawal
![Page 10: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/10.jpg)
13-10
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
![Page 11: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/11.jpg)

13-12
Creation of Money
• 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
• Deposit creation: The creation of transactions deposits by bank lending
![Page 13: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/13.jpg)
13-13
T Accounts
• T accounts are used to keep track of changes in reserves, deposit balances, and loans
• Assets are things of value the bank possesses– Cash held in a bank’s vaults– IOUs (loan obligations) from bank customers– Reserve credits at the Federal Reserve– Securities (bonds) purchased by the bank
![Page 14: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/14.jpg)
13-14
T Accounts
• Liabilities are things the bank owes to others– Bank’s largest liabilities are customers’ deposits
• The books of a bank must always balance because all of its assets must belong to someone (its depositors or its owners)
![Page 15: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/15.jpg)

13-17
The Initial Loan
• Money has been created because checking accounts are money
• Total bank reserves have remained unchanged
• Bank reserves: Assets held by a bank to fulfill its deposit obligations
![Page 18: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/18.jpg)
13-18
Secondary Deposits
• In a one bank system, when Campus Radio uses the loan, the proceeds of the loan are re-deposited in the same bank
• The bank continues to hold its entire reserves (your coins)
![Page 19: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/19.jpg)
13-19
Fractional Reserves
• Bank reserves are only a fraction of total transaction deposits
• Reserve ratio: The ratio of a bank’s reserves to its total transactions deposits
bank reservesReserve ratio
total deposits
![Page 20: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/20.jpg)
13-20
Fractional Reserves
• The Federal Reserve System requires banks to maintain some minimum reserve ratio, which limits deposit-creation lending possibilities
• Required reserves: The minimum amount of reserves a bank is required to hold
Required required totalreserves reserve ratio deposits
![Page 21: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/21.jpg)
13-21
A Multibank World
• The ability of banks to make loans depends on access to excess reserves
• Excess reserves: Bank reserves in excess of required reserves
Excess total requiredreserves reserves reserves
![Page 22: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/22.jpg)
13-22
Excess Reserves
• So long as a bank has excess reserves, it can make loans– Example: If a bank has $100 in reserves and is
required to hold $20, it can lend out excess reserves of $80
![Page 23: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/23.jpg)
13-23
Changes in the Money Supply
• In making a loan, the bank automatically increases the total money supply
• Money effectively appears out of thin air
• The creation of transaction deposits via new loans is the same as creating money
![Page 24: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/24.jpg)

13-28
The Money Multiplier
• In a multi-bank system, loans created by one bank invariably end up as reserves in another bank, which can then lend their excess reserves
• This process can theoretically continue until all banks have zero excess reserves (no more loans can be made)
![Page 29: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/29.jpg)

The Money Multiplier
• Money multiplier: The number of deposit (loan) dollars that the banking system can create from $1 of excess reserves

13-30
The Money Multiplier
• Required reserves represent leakage from the flow of money, since they cannot be used to create new loans
• Excess reserves can be used for new loans
![Page 31: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/31.jpg)

13-32
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

The Money Multiplier at Work
Original deposit = $ 100.00
Bank A loans: = $ 80.00 [=0.8 x $100.00]
Bank B loans = $ 64.00 [=0.8 x $80.00]
Bank C loans = $ 51.20 [=0.8 x $64.00]
Total money supply
= $ 500.00

13-34
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
![Page 35: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/35.jpg)

13-36
Financing Injections
• Consumer saving is a leakage, but a substantial portion is deposited in banks
• Bank deposits can be used to make loans, returning 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
![Page 37: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/37.jpg)
13-37
Constraints on Deposit Creation
• Four major constraints on deposit creation:– Deposits– Willingness to Lend– Willingness to Borrow– Regulation
![Page 38: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/38.jpg)
13-38
When Banks Fail
• In the past, “runs” of depositors rushing to withdraw their funds created panics
• Banks closed, wiping out customer deposits, curtailing lending, and often pushing the economy into recession
• In the early part of the Great Depression over 9,000 banks failed
![Page 39: 13-1 Money and Banks Chapter 13 Copyright © 2010 by the McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin.](https://reader035.fdocuments.us/reader035/viewer/2022062303/5519f9195503464c588b492d/html5/thumbnails/39.jpg)
13-39
When Banks Fail
• FDIC and FSLIC were created by Congress to ensure depositors their money was safe and eliminate motivation for bank runs
• In 2008, the U.S. was hit with another banking crisis
• Hundreds of billions of government dollars were pumped into the banking system
