The Financial Crisis and the Great Recession
14
• Start with the 2001 recession and weak recovery• Fed responds by cutting interest rates (FFR = 1%)• Since interest rates move together, mortgage
rates fell• Mortgage - A type of loan used to buy a house, which
usually serves as collateral for the loan
• Low mortgage rates increased demand for housing and led to a bubble• Increase in the price of an asset or assets that goes far
beyond what can be justified by improving fundamentals
2
2007–2009, The Great RecessionRoots of the Crisis
Roots of the Crisis
• Low interest rates on Treasuries caused investors to “reach for yield” • Investors bought riskier assets that paid greater
interest• Higher demand for junk bonds, mortgage backed
securities, etc. pushed up prices and reduced yields
• Interest rate spreads compressed• Difference between the interest rate on a risky asset
and the interest rate on a risk-free Treasury security
5
Roots of the Crisis
• Low interest rates spreads, fewer defaults and delinquencies• Lenders believed the riskier assets were not so
risky• Lax regulation• Both encouraged careless lending• Subprime mortgages – borrower fails to meet
traditional credit standards• NINJA loans – no income, no job, no assets
6
Roots of the Crisis
• More leverage
• Leverage – using borrowed money to buy an asset to boosts returns
• Vulnerabilities in our financial system• Crisis - far worse than it otherwise would have
been
7
Leverage, Profits, and Risk
• Leverage• Use of borrowed funds to purchase assets• Leverage is not per se bad, excessive leverage is
• Importance of leverage for banks
8
Table 1 Balance Sheet of Bank-a-Mythica, December 31, 2014

Leverage = Value of assets / Net worth(equity)
Leverage = $5,500 / $500 = 11
Assuming a 20% reserve requirement
Leverage, Profits, and Risk
• Importance of leverage for banks• Source of profits for banks• Bank-a-Mythica• Interest on deposits = 2%, $100,000 (2% of $5 mill)• Interest on loans = 4%, $180,000 (4% of $4.5 mill)• $80,000 profit or a 16% investor return• $80,000 / $500,000 = .16 or 16%
• Suppose the bank forced to operate without borrowed funds – they can’t borrow!

Table 2 Unleveraged Balance Sheet
11
How much return do investor’s earn?Interest on loans = 4%, $20,000 (4% of $500,000)
Return = 4%
Leverage, Profits, and Risk
• Leverage essential to bank’s profits, but leverage also exacerbates risk
• Suppose loans decline in value by 10%

Stockholders lose 10%

Stockholders lose 90%
Leverage, Profits, and Risk
• So leverage is good and bad• Magnifies returns on upside and downside
• Prior to financial crisis leverage rates increased• Traditional leverage: 10-to-1• Crazy leverage 30-to-1 to 40-to-1
• Once housing bubble burst• Bad mortgage loans, loans value declines. Value of bank
liabilities exceeds the value of • Negative net worth – insolvency.
15
Leverage, Profits, and Risk
• Four main ingredients in the witches brew before the bubble burst• The housing bubble itself• Lenient lending standards, which fed the bubble• Compressed risk spreads, which led to riskier
investments• High leverage, which increased the risk of insolvency
16
House Price Bubble and Subprime Crisis
• Housing prices in the U.S.• 2000-2006(7), increased by 60-90%• 2007-2009, dropped by 12-25%
• In some areas, 50% drop
17
House Price Bubble and Subprime Crisis
• Effects of decline in housing prices1. Decrease in residential investment• Both buying and building less attractive when
prices fall• Inventories built up pushing prices down further• From winter 2005-2006 to spring 2009, 56% drop
in construction• Drop in I reduced GDP growth in late 2005
• Effects of decline in housing prices2. Consumer wealth declined
• Led to lower consumer spending, C, in 2008 and 2009
18
House Price Bubble and Subprime Crisis
• Effects of decline in housing prices3. Increase in number of defaults and foreclosures
• During boom lending standards fell in three ways• Old fashioned rules ignored: > 25-33%• Loans granted with low or 0 down payments• More and more subprime mortgages
• As housing prices fell, subprime mortgages started to default
• House of cards started to crumble
19
From Housing Bubble To Financial Crisis
• How do we misread the signals from the subprime mortgage problem?• Underestimated the volume of subprime
mortgages• Poor understanding of financial instruments and
potential risk
20
From Housing Bubble To Financial Crisis
• Some aspects of finance• Securitization• Loans are transformed into marketable securities• Packaged together into a bond-like instrument that can
be sold to investors
• Mortgage-backed security, MBS• A type of bond whose interest payments and principal
repayments derive from monthly mortgage payments of many households
21
From Housing Bubble To Financial Crisis
• MBS’s reduce risks in two ways• Geographical diversification: prices won’t fall
everywhere• Risks spread out over thousands of investors
• So what happened?• Housing bubble burst nationally
• MBS’s riskier than thought so market values fell
• Not as widely held as thought• Failure of Bear Stearns, Lehman Brothers etc. related
to excessive concentrations of mortgage-related risks
22
From Housing Bubble To Financial Crisis
• MBS’s and related assets more complex than we realized• As some mortgages went into default, all MBS’s
affected• Nobody knew what they were really worth• Values plummeted, panic summer 2007
• STOP HERE, p286!!!
