25 standard deviations in a blue moon

One of the funniest moments in the great credit crunch of 2007 came in the summer. “We were seeing things that were 25-standard-deviation events, several days in a row,” said David Viniar, CFO of the smartest financial firm in the world, Goldman Sachs. That Viniar. What a comic. According to Goldman’s mathematical models, August, Year of Our Lord 2007, was a very special month. Things were happening then that were only supposed to happen about once in every 100,000 years. Either that… or Goldman’s models were wrong.
We recall looking out of our window. Outside, we saw a summer day much like any other. And inside, what we saw in the news was also rather typical – a credit crunch. No, credit crunches don’t come along every day… but nor do 100,000 years separate one from another.
In the US, recently, we have had the crash of the dotcoms, the crash of Long Term Capital in 1998 and the crash of 1987; outside of the US, there have been a number of credit crunches, in Japan, Russia, Mexico and various Asian countries. When you make loans to people who can’t pay the money back, trouble is only a couple of standard deviations away. So far, during the first eight months of 2007, some 1.7 million houses have been caught up in foreclosure proceedings in the US. That is just the beginning. According to Congressional estimates, up to two million families are expected to lose their homes over the next two years.
The individual amounts of money weren’t very large, not by Wall Street standards. But when the money didn’t show up, it had an alarming effect. This week’s press brings estimates of total losses of over $13bn at Citi. Morgan Stanley is said to be facing $8bn in losses. Merrill Lynch set records with estimated losses of $18bn. The cat still has Goldman Sachs’ tongue. But when the losses are totted up, they will probably be spectacular. In total there is more than $1trn in subprime debt outstanding; much of it will go bad.
Already heads have begun to roll. First, Warren Spector of Bear Stearns got axed. Then, it was Peter Wuffli at UBS. He was followed by Stan O’Neal of Merrill Lynch. O’Neal made the headlines when he was pushed out of the corporate jet with a ‘golden parachute’ valued at $160m. After O’Neal hit the ground, along came Chuck Prince of Citigroup – America’s largest bank. The firm is expected to write down $5bn this quarter alone. Chuck was chucked out. What went wrong? The business model seemed so simple. You bought subprime loans from the knaves who made them then you cut them up, dicing them into a kind of mortgage spam. You got rating agencies to bless them and then you sold them to naïve investors. The idea was to earn huge fees upfront – while laying the risk onto the fools who bought the stuff.
When the going was good, it looked as though no business could be better. You were providing a public service, helping people buy houses, by redistributing the risk from the people who incurred it to people who had no idea it was there. And you earned such large fees you would get your picture in the paper, build a huge mansion in Greenwich and acquire some abominable paintings to put on the walls.
But wrong it did go. The FT provides more detail on what happened at Citigroup: “The bank reported that, at the end of September, it had around $2.7bn of unsold collateralised debt obligations – pools of debt securities that are repackaged and distributed to other investors. But it also had $4.2bn of subprime loans it had bought in the past six months, and about $4.8bn of loans to customers which were secured by subprime collateral. In addition, the bank had $43bn of exposure to the most highly rated tranches of CDOs based on subprime mortgage assets”.
It turns out Citi was fool and knave at the same time. It sold dubious subprime debt to its customers. But it bought it too – and took it as collateral. Gary Crittenden, Citi’s chief financial officer, claimed on Monday that the firm was simply a victim of unforeseen events. The losses were “driven by some events that have happened during the month of October”, he said, referring to downgrades by rating agencies.
No mention was made of the previous five years, when Citi was busily consolidating mortgage debt from people who weren’t going to repay, pronouncing it ‘investment grade’, mongering it to its clients and stuffing it into its own portfolio, while paying itself billions in fees and bonuses.
No, according to the masters of the universe, downgrades by Moody’s and Fitch’s were completely unexpected – like the eruption of Vesuvius; even the gods were caught off guard. Apparently, as of 30 September, Citigroup’s subprime portfolio was worth every penny of the $55bn Citi’s models said it was worth. Then, whoa, in came one of those 25-sigma events. Citi was whacked by a fat tail. Who could have seen that coming?
