"Agency costs" is a term used to describe the costs in a situation where the interests of two parties are not perfectly aligned. There were potential agency costs between the originators of mortgages and investors, and employees of banks who earned bonuses and the banks themselves.

3 basis points.

The Put Option Impact

As borrowers exercised their put option, the supply of homes on the market further increased (pushing home prices even lower). Which lead to bizarre incentives for homeowners.

Which of the following describes the waterfall typically used for mortgages pre-crisis? A. A distribution of cash flows to tranches with priority given to tranche with the highest rating. B. A distribution of cash flows to tranches in proportion to their outstanding principals. C.

Explain why the AAA-rated tranche of an ABS CDO is more risky than the AAA-rated tranche of an ABS.

A moderately high default rate will wipe out the tranches underlying the ABS CDO so that the AAA-rated tranche of the ABS CDO is also wiped out. A moderately high default rate will at worst wipe out only part of the AAA-rated tranche of an ABS.

Which of the following would be described by the term "liar loan"? A. A situation where the lender concealed information from the borrower. B. A situation where the lender lied to the borrower about the interest rate. C. A situation where the borrower lied about his or her income. D. None of the above.

A situation where the borrower lied about his or her income.

What is a subprime mortgage?

A subprime mortgage is a mortgage where the risk of default is higher than normal. This may be because the borrower has a poor credit history or the ratio of the loan to value is high or both.

An index of house prices.

Explain the impact of an increase in default correlation on the risks of the senior tranche of an ABS. What is its impact on the risks of the equity tranche?

As default correlation increases, the senior tranche of a CDO becomes more risky because it is more likely to suffer losses. It therefore becomes less valuable. As default correlation increases, the equity tranche becomes more valuable. To understand why this is so, note that in the limit when there is perfect correlation there is a high probability that there will be no defaults and the equity tranche will suffer no losses.

What are the values of interest rate swaps?

At initiation: Designed to have an initial value of zero. After initiation: Valued as the difference between the value of a fixed-rate bond and the value of a floating-rate bond. Currency swaps are also valued the same way.

Why are interest rate swaps so popular?

Because some companies have a comparative advantage when borrowing in fixed-rate markets, and others find comparative advantage when borrowing in floating-rate markets.

When was the birth of the swap market?

In 1981, IBM and The World Bank both had debt. IBM's debt was in German and Swiss currency. The World Bank's debt was US dollar denominated. The two companies agreed to "swap" the interest payments on their debt. World Bank payed IBM's German and Swiss interest payments, and IBM would pay World Bank's US interest payments.

The Bubble Bursts

In 2007, many home buyers found they could no longer afford their payments after the "teaser" rate expired. Their inability to pay led to foreclosures, which increased the number of homes on the market (this increase in supple decreased home prices).

Why is the expected loss to a bank from a default on a swap less than the expected loss from the default on a loan to the counterparty with the same principal?

In an interest-rate swap a financial institution's exposure depends on the difference between a fixed-rate of interest and a floating-rate of interest. It has no exposure to the notional principal. In a loan the whole principal can be lost.

What went wrong?

Investors often assumed that a BBB-rated MBS tranche could be equated with a BBB-rated corporate bond in terms of risk. However, thinly sliced tranches of a MBS (1% or 2% of total principle) have a high probability of experiencing no loss or complete loss. Losses on a BBB-rated bond portfolio are unlikely to exceed 25%, but losses of 100% were very possible for thin BBB-rated MBS tranches.

How were the risks in ABS CDOs misjudged by the market?

Investors underestimated how high the default correlations between mortgages would be in stressed market conditions. Investors also did not always realize that the tranches underlying ABS CDOs were usually quite thin so that they were either totally wiped out or untouched. There was an unfortunate tendency to assume that a tranche with a particular rating could be considered to be the same as a bond with that rating. This assumption is not valid for the reasons just mentioned.

AIG lost money because: A. It bought tranches created from mortgages. B. It invested heavily in real estate. C. It invested heavily in the stock market. D. It insured AAA tranches of ABS CDOs.

It insured AAA tranches of ABS CDOs.

Originators - Generate "acceptable" mortgages. Appraisers - Overvalue homes. MBS Creators - Game published rating criteria. MBS Raters - Understate riskiness. Traders - Create short-term profits.

Which of the following is true as the correlation between mortgage defaults increases? A. Equity tranches are almost certain to incur losses. B. Senior tranches become more likely to incur losses. C. The expected number of defaults increases. D. Equity tranches are unaffected.

Senior tranches become more likely to incur losses.

Why did mortgage lenders frequently not check on information provided by potential borrowers on mortgage application forms during the 2000 to 2007 period?

Subprime mortgages were frequently securitized. The only information that was retained during the securitization process was the applicant's FICO score and the loan-to-value ratio of the mortgage.

Which of the following describes the five-year swap rate? A. The fixed rate of interest which a swap market maker is prepared to pay in exchange for LIBOR on a 5-year swap. B.

A bank finds that its assets are not matched with its liabilities. It is taking floating-rate deposits and making fixed-rate loans. How can swaps be used to offset the risk?

The bank is paying a floating-rate on the deposits and receiving a fixed-rate on the loans. It can offset its risk by entering into interest rate swaps (with other financial institutions or corporations) in which it contracts to pay fixed and receiving floating.

Sometimes A is true and sometimes B is true.

The early forward contracts underlying the swap have a negative value and the later ones have a positive value.

Explain why the end-of-year bonus is sometimes referred to as "short-term compensation".

The end-of-year bonus usually reflects performance during the year. This type of compensation tends to lead traders and other employees of banks to focus on their next bonus and therefore have a short-term time horizon for their decision making.

The increase in the price of houses was caused by the unsustainable factors.

What is a mezzanine tranche?

The mezzanine tranche of an ABS or ABS CDO is a tranche that is in the middle as far as seniority goes. It is ranked below the senior tranches and therefore absorbs losses before they do. It ranks above the equity tranche (so that the equity tranche absorbs losses before it does).

The value of the swap does not change providing the swap rate remains the same.

The value of the swap to the company increases.

What is the waterfall in a securitization?

The waterfall defines how the cash flows from the underlying assets are allocated to the tranches. In a typical arrangement, cash flows are first used to pay the senior tranches their promised return. The cash flows (if any) that are left over are used to provide the mezzanine tranches with their promised returns. The cash flows (if any) that are left over are then used to provide the equity tranches with their promised returns. Any residual cash flows are used to pay down the principal on the senior tranches.

What is an originator?

They are the businesses that made the initial loan.

How was an ABS CDO created? What was the motivation to create ABS CDOs?

Typically an ABS CDO is created from the BBB-rated tranches of an ABS. This is because it is difficult to find investors in a direct way for the BBB-rated tranches of an ABS.
