From Zero Hedge:
The Bank Stress Test(1) “more than 150 senior supervisors, on-site examiners, analysts and economists” spent a month reviewing the 19 BHC’s that hold two thirds of the country’s bank assets and account for one half of the loans
More than 150 means at least 151. Is the US Iceland or something? Ten trillion dollars in assets and five hundred trillion dollars in derivatives in one month? A typical single bank examination utilizes hundreds of examiners and takes several months. Clearly the next release of public sector productivity numbers is going to astonish.
That's less than 10 per bank--EPJ
(2) ”the firms were asked to project…..the firms were asked to provide…etc.”In other words, the banks tested themselves and the 150 examiners took their word for it. Any wonder they passed?...
“Supervisors evaluated firm loss estimates using a Monte Carlo simulation that projected a distribution of losses by examining potential dispersion around central probabilities of default.”
Ah…smells like Gaussian distributions. The old standard. We have seen how well that assumption works in these unusual times. An example of the dependability of using Gauss, taken from stock market movements in October, and calculated by Nassim Nicholas Taleb of Black Swan fame, showed that the price movements seen in October 2008 could be expected to occur---using estimates based on Gaussian distributions---once every 73,000,000,000,000,000,000,000 years.For those of you not tied to Biblical strict constructionism, the Universe is around 18,500,000,000 years old. Looks like it will be a few quintillion years before we see October again...
Take a good look at just how complex and thorough this “test” was. An online dating questionnaire is more probing.
