How Wall Street wizards conjured up sub-prime's hurricane Norma
Carrick Mollenkamp and Serena Ng | December 29, 2007
IN recent years, as home prices and mortgage lending boomed, bankers found ever-more-clever ways to repackage trillions of dollars in loans, selling them off in slivers to investors around the world. Financiers and regulators figured all the activity would disperse risk, and maybe even make markets safer and stronger.
Then along came
Norma.
Norma CDO I Ltd, as its full name goes, is one of a new breed of mortgage investments created in the waning days of the US housing boom. Instead of spreading the risk of a global home finance boom, the instruments have magnified and concentrated the effects of the sub-prime mortgage bust. They are now behind tens of billions of dollars of writedowns at some of the world's largest banks, including the $US9.4 billion ($10.7 billion) announced last week by Morgan Stanley.
...
Only nine months after selling $US1.5 billion in securities to investors, Norma is worth a fraction of its original value. Credit rating firms, which once signed off approvingly on the deal, have slashed its ratings to junk. The concept behind Norma, known as a
collateralised debt obligation, has been in use since the 1980s. A
CDO, most broadly, is a device that repackages the income from a pool of bonds, derivatives or other investments. A mortgage CDO might own pieces of a hundred or more bonds, each of which contains thousands of individual mortgages. Ideally, this diversification makes investors in the CDO less vulnerable to the problems of a single borrower or security.
....
In principle, credit default swaps help banks and other investors pass along risks they don't want to keep. But in the case of sub-prime mortgages, the
derivatives have magnified the effect of losses, because they allowed bankers to create an unlimited number of CDOs linked to the same mortgage-backed bonds. UBS Investment Research, a unit of Swiss bank UBS AG, estimates that CDOs sold credit protection on roughly three times the actual face value of sub-prime bonds rated triple-B.
The use of derivatives "multiplied the risk," says Greg Medcraft, an Australian who is chairman of the American Securitisation Forum, an industry association. "The sub-prime mortgage crisis is far greater in terms of potential losses than anyone expected because it's not just physical loans that are defaulting."
....
Such cross-selling benefited banks, because it helped support the flow of new CDOs and underwriting fees. In fact,
the bulk of the middle-rated pieces of CDOs underwritten by Merrill were purchased by other CDOs that the investment bank arranged,
(What does this mean?) according to people familiar with the matter. Each CDO sold some of its riskier slices to the next CDO, which then sold its own slices to the next deal, and so on.
Critics say the cross-selling reached such proportions that it artificially propped up the prices of CDOs. Rather than widely dispersing exposure to these mortgages, the practice circulated the same risk among a relatively small number of players.
