Causes of the Subprime Crisis
• The US Treasury Secretary Hank Paulson has said repeatedly that the "root cause" of the problem is "the housing correction, which has resulted in illiquid mortgage-related assets that are choking off the flow of credit."
• John Rosner (2008 Sep. 30, the Standards) disagreed that "the troubled assets are the result, not the cause, of loose lending practices, a housing bubble that burst, a glut of unsold homes and home prices that are still too high relative to incomes and rental costs."
Causes of the Subprime Crisis
• Greedy?
• Loose Lending Practices? NINJA loans?
• Securitization of Mortgages? Problematic Credit Rating?
• Copula Assumption of Risk? Long Tail Effect?
• Complex investment vehicles (MBS, CDO, CDS)?
• Chinamerica? China saves too much? US spends too much?
• Negative RIR? Fiat Money?
• All the above?
• None of the above?
What is a Subprime Mortgage
• A subprime mortgage is a type of loan granted to individuals with poor credit histories, who, as a result of their deficient credit ratings, would not be able to qualify for conventional mortgages. Because subprime borrowers present a higher risk for lenders, subprime mortgages charge interest rates above the prime lending rate.
• NINJA Loans: Mortgage loans to ones who are No-Income, No-Job or Assets.
• Non-recourse Debt: If the borrower defaults, the issuer can seize the collateral, but cannot seek out the borrower for any further compensation, even if the collateral does not cover the full value of the defaulted amount. This is one instance where the borrower does not have personal liability for the loan.

What is CDO? A collateralized debt obligation (CDO) is
a type of structured asset-backed security
(ABS), and mortgage-backed security
(MBS).
a CDO can be thought of as a
promise to pay investors in a
prescribed sequence, based on the
cash flow the CDO collects from the
pool of bonds or other assets it
owns. The CDO is "sliced" into
"tranches",
1 MBS -> n CDOs (Amplification)
What is CDS? • A credit default swap (CDS) is a
financial swap agreement that the seller
of the CDS will compensate the buyer in
the event of a loan default.
• It was invented by JP Morgan in 1994.
• A CDS is considered insurance against
non-payment.
• A buyer of a CDS might be speculating
on the possibility that the third party will
indeed default.
• Default risk is transferred to other CDS
buyers, thus moral hazard.
CDO+CDS = Risk-free Asset?
• If CDS sellers default?
(counterparty risk)
• i.e if insurance companies go
bankrupt, how to insure the
insurers?
Gaussian Copula Model
• The crisis exposed significant weaknesses in the Coupla model. The underlying
assumption of the model that correlations between different assets where
constant over time and could be combined into one number, had proved to be an
serious misjudgement;
• The most popular approach to find the distributions for the time to default (Rj,Ri),
was to use observed market data from another type of CDS. (Forslund and
Johansson 2012);
• Result in a general underestimation of risk, and overconfidence.

Global Finance
Money is fiat, real interest rate can be Negative
An Analogy: A win-win?
• No business
• Few customers
• Overstocks
Retailer
• No savings
• Spendaholic (cannot stop from consuming)
Shopper
• Retailer offers low interest non-callable and recyclable loans to shoppers
• A win-win solution?
• Good business of the retailer
• Unlimited spending of the shopper
