Originally posted by Parallax I remember that, too. Again, though; that in itself had no effect.
After the value went down, they were still living in the house, making the same payments. Nothing changed there. The only way they knew the value had gone down was that someone told them.
For some, yes, but we lived in Utah at the time, and about 1/2 of the people who moved there to open the new processing center left within a year, and most of them left the house to the bank. (We stayed 1.5 years, and made a little on ours, as we bought a craftsman bungalow, something that was just coming into style, instead of a cookie cutter development)
A major difference is that in '84 Lou Ranieri was still forming the new mortgage pool market; the derivatives and derivatives of derivatives and synthetic derivatives thereof were still far in the future. Thus a spike in defaults mainly hit bank balance sheets the usual way, and only a certain number of mortgage pools.
As Gene says, this last time the sheer amount of dollars involved was huge to begin with, and add to that the derivative manufacturing and pricing, and re-selling, with added leverage at each step, and you end up with a really really big number.
The easiest derivative to understand is the strip: we started this with treasuries but quickly addapted it to other asset classes. With the strip, you clip off each coupon payment, and package these into separate tranches. So you can buy, say, the interest payments that come due next year, or 10 years from now. Obviously, the worth of the 10 year out payments is riskier than the ones that come due next year - not just from default, but the underlying loans may be paid off early etc. Then there's the leftover pieces, the riskiest bits of all, the bits that only get paid off, and get any return, if everything goes just right with the underlying securities. These were the bits that banks ended up holding, as they weren't able to sell them - the money they made off the other tranches *should have* more than made up for any losses here.
And remember, the banks put up $1 for $26 worth of these.
So any decline in value immediately multiplies and amplifies through the system. And mark to market means the banks suddenly have no capital to cover the paper losses... and would YOU lend anything to such a bank, not knowing if you'd get it back?
