Well, at the risk of having James agree with me again, I'll tell you what I think (and it's all supposition):
I'm sure everyone has heard the term "toxic asset" by now. For those that are unsure what it means, it refers to an asset--something a company owns--that has lost so much value, there is no one willing to buy it. Effectively, it is worthless. But it's still on the books as an asset.
Moffett (the new CEO of Freddie that up and quit) and Kellermann were going non-stop, trying to rebuild Freddie's financial structure. What I think they discovered--and I have ZERO evidence for this--is that some of these so-called toxic assets weren't such after all. Why? Because they don't really exist as assets. I think that some of the more exotic financial packages based on mortgages, created by Wall Street in the past fifteen or so years--are fantasies. I think PHD'd analysts cooked them up, then got approval from the Feds, thanks to help from Fannie and Freddie execs, who were the epitome of greedy bastards: doing absolutely no work but getting filthy rich (I'm talking here about Franklin Raines, Jaime Gorelick, and the like). The leadership at Freddie and Fannie was beyond clueless, since it was hardly made up of serious thinkers. But it was given an opportunity to make money and achieve Federal housing goals. So it jumped on this crap.
Now, with all the analysis out there and with some actual scrutiny of these things, I think maybe someone has realized that these assets are nothing but documentation, that to own them--toxic or not--is to own nothing. But the Fed are saying they'll buy the toxic assets of financials. Where will those new purchases end up? You guessed it.
I can't say why Kellermann took his own life. That's a tragedy. But he's been at Freddie forever--mostly as an analyst. And if even part of what I am saying is right...
