• What is money?
• What assets are considered “money”? What are the functions of money? The types of money?
• What is the Federal Reserve?
• What role do banks play in the monetary system? How do banks “create money”?
• How does the Federal Reserve control the money supply?

What Money Is and Why It’s Important
Without money, trade would require barter, the exchange of one good or service for another.
Every transaction would require a double coincidence of wants—the unlikely occurrence that two people each have a good the other wants.

What Money Is and Why It’s Important
Most people would have to spend time searching for others to trade with—a huge waste of resources.
This searching is unnecessary with money, the set of assets that people regularly use to buy g&s from other people.

Four Properties of Money
Nonperishable, durable and easy to store
Portable
Easily divisible
Scarce and hard to counterfeit

The 3 Functions of Money
Medium of exchange: an item buyers give to sellers when they want to purchase g&s
Unit of account: the yardstick people use to post prices and record debts
Store of value: an item people can use to transfer purchasing power from the present to the future

Very Brief History of Money
1200 B.C.: Cowrie Shells
The first use of cowries was in China.
Cowrie shells were widely available in the shallow waters of the Pacific and Indian Oceans.
The cowrie is the most widely and longest used currency in history.
1111
Very Brief History of Money
1000 B.C.: First Metal Money and Coins
Bronze and Copper cowrie imitations were manufactured by China at the end of the Stone Age and could be considered some of the earliest forms of metal coins.
1212
Very Brief History of Money
500 B.C.: Modern Coinage
Outside of China, the first coins developed out of lumps of silver.
They soon took the familiar round form of today, and were stamped with various gods and emperors to mark their authenticity.
These early coins first appeared in Lydia, which is part of present-day Turkey, but the techniques were quickly copied and further refined by the Greek, Persian, Macedonian, and later the Roman empires.

Very Brief History of Money
118 B.C.: Leather Money
Leather money was used in China in the form of one-foot-square pieces of white deerskin with colorful borders.
This could be considered the first documented type of banknote.

Very Brief History of Money
806: Paper Currency
The first known paper banknotes appeared in China.
In Europe, the concept of banknotes was first introduced during the 13th century by travelers such as Marco Polo, with proper banknotes appearing 1661 in Sweden.

Very brief history of money
The Gold Standard
Gold was officially made the standard of value in England in 1816.
1930s: the end of Gold Standard
1944: return to Gold Standard (Bretton Woods International Monetary Agreement)
1971: The “Nixon Shock” – end of Gold Standard
1616
Origin of the Word “Dollar”
The word dollar is much older than the American unit of currency.
It is an Anglicized form of "thaler", (pronounced taler, with a long "a"), the name given to coins first minted in 1519 from locally mined silver in Joachimsthal (Jáchymov) in Bohemia.
Thaler is a shortened form of the term by which the coin was originally known - Joachimsthaler.
1717
The 2 Kinds of Money
Commodity money: takes the form of a commodity with intrinsic value
Examples: gold coins, cigarettes in POW camps
Fiat money: money without intrinsic value, used as money because of govt decree
Example: the U.S. dollar
1818
Contaminated Currency
In 1994, the U.S. 9th Circuit Court of Appeals determined that in Los Angeles, out of every four banknotes, on average more than three are tainted by cocaine or another illicit drug.
In a study reported in Forensic Science International, A.J. Jenkins, the author reports the analysis of ten randomly collected one-dollar bills from five cities, and tested for cocaine, heroin, 6-acetylmorphine (also called "6-AM"), morphine, codeine, methamphetamine, amphetamine and phencyclidine (PCP).
Results demonstrated that 92% of the bills were positive for cocaine while heroin was detected in seven bills.
Forensic scientists have said that around 80% of all British banknotes contain traces of drugs.
Similar contaminations have been found on euro banknotes from Ireland, Spain, and Germany.
1919
The Money Supply
The money supply (or money stock):the quantity of money available in the economy
What assets should be considered part of the money supply? Two candidates: Currency: the paper bills and coins in the
hands of the (non-bank) public Demand deposits: balances in bank accounts
that depositors can access on demand by writing a check
2020
Measures of the U.S. Money Supply M1: narrowest and most liquid measure of money currency, demand deposits,
traveler’s checks, and other checkable deposits.
M1 = $2.7 trillion (February 2014)
M2: a boarder measure
everything in M1 plus savings deposits, small denomination time deposits (less than $100,000), money market mutual funds, and a few minor categories.
M2 = $11.1 trillion (February 2014)
When we talk about “the money supply” in this course you should
think about it as M1.
2121
Central Banks & Monetary Policy
Central bank: an institution that oversees the banking system and regulates the money supply
Monetary policy: the setting of the money supply by policymakers in the central bank
Federal Reserve (Fed): the central bank of the U.S.
2222
The Structure of the FedThe Federal Reserve System consists of: Board of Governors
(7 members), located in Washington, DC
12 regional Fed banks, located around the U.S.
Federal Open Market Committee (FOMC), includes the Bd of Govs and presidents of some of the regional Fed banks The FOMC decides monetary policy.
Ben S. BernankeChair of FOMC,
Feb 2006 – Jan 2014
2323
New Chairman of the Fed
Janet YellenChair of FOMC,
Feb 2014 – present
1st Woman serving as a Chair of the Fed.She graduated from Fort Hamilton High School in the Bay Ridge section of Brooklyn.She graduated summa cum laude from Pembroke College (Brown University) with a degree in economics in 1967.Received her Ph.D. in economics from Yale University in 1971.Yellen is considered by many on Wall Street to be a "dove" (more concerned with unemployment than with inflation) as opposed to a “hawk”.Yellen is a Keynesian economist.
2424
Bank Reserves
In a fractional reserve banking system, banks keep a fraction of deposits as reserves and use the rest to make loans.
The Fed establishes reserve requirements, regulations on the minimum amount of reserves that banks must hold against deposits.
Banks may hold more than this minimum amount if they choose.
The reserve ratio, R= fraction of deposits that banks hold as reserves= total reserves as a percentage of total deposits
2525
Bank T-Account T-account: a simplified accounting statement
that shows a bank’s assets & liabilities.
Example: FIRST NATIONAL BANK
Assets Liabilities
Reserves $ 10
Loans $ 90
Deposits $100
Banks’ liabilities include deposits, assets include loans & reserves.
In this example, notice that R = $10/$100 = 10%.
2626
Banks and the Money Supply: An Example
Suppose $100 of currency is in circulation.
To determine banks’ impact on money supply, we calculate the money supply in 3 different cases:
1. No banking system
2. 100% reserve banking system: banks hold 100% of deposits as reserves, make no loans
3. Fractional reserve banking system
2727
Banks and the Money Supply: An Example
CASE 1: No banking system
Public holds the $100 as currency.
Money supply = $100.
2828
Banks and the Money Supply: An Example
CASE 2: 100% reserve banking system
Public deposits the $100 at First National Bank (FNB).
FIRST NATIONAL BANK
Assets Liabilities
Reserves $100
Loans $ 0
Deposits $100
FNB holds 100% of deposit as reserves:
Money supply = currency + deposits = $0 + $100 = $100
In a 100% reserve banking system, banks do not affect size of money supply.
2929
Banks and the Money Supply: An Example
CASE 3: Fractional reserve banking system
Depositors have $100 in deposits, borrowers have $90 in currency.
Money supply = C + D = $90 + $100 = $190 (!!!)
FIRST NATIONAL BANK
Assets Liabilities
Reserves $100
Loans $ 0
Deposits $100
Suppose R = 10%. FNB loans all but 10% of the deposit:
10
90
3030
Banks and the Money Supply: An Example
How did the money supply suddenly grow?
When banks make loans, they create money.
The borrower gets $90 in currency—an asset counted in the
money supply $90 in new debt—a liability that does not have
an offsetting effect on the money supply
CASE 3: Fractional reserve banking system
A fractional reserve banking system creates money, but not wealth.
3131
Banks and the Money Supply: An Example
CASE 3: Fractional reserve banking system
If R = 10% for SNB, it will loan all but 10% of the deposit.
SECOND NATIONAL BANK
Assets Liabilities
Reserves $ 90
Loans $ 0
Deposits $ 90
Borrower deposits the $90 at Second National Bank.
Initially, SNB’s
T-account looks like this:
9
81
3232
Banks and the Money Supply: An Example
CASE 3: Fractional reserve banking system
If R = 10% for TNB, it will loan all but 10% of the deposit.
THIRD NATIONAL BANK
Assets Liabilities
Reserves $ 81
Loans $ 0
Deposits $ 81
SNB’s borrower deposits the $81 at Third National Bank.
Initially, TNB’s
T-account looks like this:
$ 8.10
$72.90
3333
Banks and the Money Supply: An Example
CASE 3: Fractional reserve banking system
The process continues, and money is created with each new loan.
Original deposit =FNB lending =
SNB lending = TNB lending =
...
$
100.00$
90.00$
81.00$
72.90...
Total money supply =$
1000.00
In this example, $100 of reserves
generates $1000 of money.
3434
The Money Multiplier
Money multiplier: the amount of money the banking system generates with each dollar of reserves
The money multiplier equals 1/R.
In our example, R = 10% money multiplier = 1/R = 10$100 of reserves creates $1000 of money

Banks and the money supply
While cleaning your apartment, you look under the sofa cushion and find a $50 bill (and a half-eaten taco). You deposit the bill in your checking account.
The Fed’s reserve requirement is 20% of deposits.
A. What is the maximum amount that the money supply could increase?
B. What is the minimum amount that the money supply could increase?
A C T I V E L E A R N I N G 1
Answers
If banks hold no excess reserves, then money multiplier = 1/R = 1/0.2 = 5
The maximum possible increase in deposits is 5 x $50 = $250
But money supply also includes currency, which falls by $50.
Hence, max increase in money supply = $200.
You deposit $50 in your checking account.
A. What is the maximum amount that the money supply could increase?
A C T I V E L E A R N I N G 1
Answers
Answer: $0
If your bank makes no loans from your deposit, currency falls by $50, deposits increase by $50, money supply does not change.
You deposit $50 in your checking account.
A. What is the maximum amount that the money supply could increase? Answer: $200
B. What is the minimum amount that the money supply could increase?

A More Realistic Balance Sheet
Assets: Besides reserves and loans, banks also hold securities.
Liabilities: Besides deposits, banks also obtain funds from issuing debt and equity.
Bank capital: the resources a bank obtains by issuing equity to its owners Also: bank assets minus bank liabilities
Leverage: the use of borrowed funds to supplement existing funds for investment purposes
4242
A More Realistic Balance Sheet
MORE REALISTIC NATIONAL BANK
Assets Liabilities
Reserves $ 200
Loans $ 700
Securities $ 100
Deposits $ 800
Debt $ 150
Capital $ 50
Leverage ratio: the ratio of assets to bank capital
In this example, the leverage ratio = $1000/$50 = 20
Interpretation: for every $20 in assets, $ 1 is from the bank’s owners, $19 is financed with borrowed money.
4343
Leverage Amplifies Profits and Losses
In our example, suppose bank assets appreciate by 5%, from $1000 to $1050. This increases bank capital from $50 to $100, doubling owners’ equity.
Instead, if bank assets decrease by 5%, bank capital falls from $50 to $0.
If bank assets decrease more than 5%, bank capital is negative and bank is insolvent.
Capital requirement: a govt regulation that specifies a minimum amount of capital, intended to ensure banks will be able to pay off depositors and debts.
4444
Leverage and the Financial Crisis
In the financial crisis of 2008–2009, banks suffered losses on mortgage loans and mortgage-backed securities due to widespread defaults.
Many banks became insolvent:In the U.S., 27 banks failed during 2000–2007, 166 during 2008–2009.
Many other banks found themselves with too little capital, responded by reducing lending, causing a credit crunch.
4545
The Government’s Response
To ease the credit crunch, the Federal Reserve and U.S. Treasury injected hundreds of billions of dollars’ worth of capital into the banking system.
This unusual policy temporarily made U.S. taxpayers part-owners of many banks.
The policy succeeded in recapitalizing the banking system and helped restore lending to normal levels in 2009.
4646
The Fed’s Tools of Monetary Control Earlier, we learned
money supply = money multiplier × bank reserves
The Fed can change the money supply by changing bank reserves or changing the money multiplier.
4747
How the Fed Influences Reserves Open-Market Operations (OMOs):
the purchase and sale of U.S. government bonds by the Fed.
If the Fed buys a government bond from a bank, it pays by depositing new reserves in that bank’s reserve account. With more reserves, the bank can make more loans, increasing the money supply.
To decrease bank reserves and the money supply, the Fed sells government bonds.
4848
How the Fed Influences Reserves The Fed makes loans to banks, increasing their
reserves. Traditional method: adjusting the discount rate
—the interest rate on loans the Fed makes to banks—to influence the amount of reserves banks borrow
New method: Term Auction Facility—the Fed chooses the quantity of reserves it will loan, then banks bid against each other for these loans.
The more banks borrow, the more reserves they have for funding new loans and increasing the money supply.
4949
How the Fed Influences the Reserve Ratio
Recall: reserve ratio = reserves/deposits,which inversely affects the money multiplier.
The Fed sets reserve requirements: regulations on the minimum amount of reserves banks must hold against deposits.
Reducing reserve requirements would lower the reserve ratio and increase the money multiplier.
Since 10/2008, the Fed has paid interest on reserves banks keep in accounts at the Fed. Raising this interest rate would increase the reserve ratio and lower the money multiplier.
5050
Problems Controlling the Money Supply
If households hold more of their money as currency, banks have fewer reserves, make fewer loans, and money supply falls.
If banks hold more reserves than required, they make fewer loans, and money supply falls.
Yet, Fed can compensate for household and bank behavior to retain fairly precise control over the money supply.
5151
Bank Runs and the Money Supply A run on banks:
When people suspect their banks are in trouble, they may “run” to the bank to withdraw their funds, holding more currency and less deposits.
Under fractional-reserve banking, banks don’t have enough reserves to pay off ALL depositors, hence banks may have to close.
Also, banks may make fewer loans and hold more reserves to satisfy depositors.
These events increase R, reverse the process of money creation, cause money supply to fall.
5252
Bank Runs and the Money Supply During 1929–1933, a wave of bank runs and
bank closings caused money supply to fall 28%.
Many economists believe this contributed to the severity of the Great Depression.
Since then, federal deposit insurance has helped prevent bank runs in the U.S.
In the U.K., though, Northern Rock bank experienced a classic bank run in 2007 and was eventually taken over by the British government.
5353
The Federal Funds Rate
On any given day, banks with insufficient reserves can borrow from banks with excess reserves.
The interest rate on these loans is the federal funds rate.
The FOMC uses OMOs to target the fed funds rate.
Changes in the fed funds rate cause changes in other rates and have a big impact on the economy.

• Money serves three functions: medium of exchange, unit of account, and store of value.
• There are two types of money: commodity money has intrinsic value; fiat money does not.
• The U.S. uses fiat money, which includes currency and various types of bank deposits.
S U M M A RY
• In a fractional reserve banking system, banks create money when they make loans. Bank reserves have a multiplier effect on the money supply.
• Because banks are highly leveraged, a small change in the value of a bank’s assets causes a large change in bank capital. To protect depositors from bank insolvency, regulators impose minimum capital requirements.
S U M M A RY
• The Federal Reserve is the central bank of the U.S., is responsible for regulating the monetary system.
• The Fed controls the money supply mainly through open-market operations. Purchasing govt bonds increases the money supply, selling govt bonds decreases it.
• In recent years, the Fed has set monetary policy by choosing a target for the federal funds rate.
