"unlinked from cash settlement values" - I have no idea what this is supposed to mean. Equity, in many ways, is far more opaque than almost any derivative. It's value is linked to an invisible future earning stream. Derivatives, at least, are priced on (mostly) observable assets.
The problem, as a derivatives trader in a very hard hit part of fixed income, is not so much "valuation" or "repricing" or the usual bylines. If everyone had adequate capital, it wouldn't have been a problem. Price discovery in a relative illiquid market is nothing new to the world.
The problem is fiduciary-duty-by-ratings type of incentive that regulations created in the first place allowed otherwise low-risk-tolerance investors to invest with leverage in stuff with a lot of embedded risk; and when that blew up, these large investors (AIG, pension funds, etc) took the system with them.
Meanwhile, all this talk of CDS bringing companies down are just scar mongering. Vulture distress funds have been around for ages and act perfectly within their legal (and I argue, economic) obligations. CDS, if anything, gave them a little more efficiency. But what's wrong with that.
Again, I advocate that we regulate incentives, not tools. We'll never win the arms race against smart motivated people. And if we do, we lose anyway (in terms of productivity, efficiency, etc)
Quote from PragmaticIdeals:
Bingo. There's not NEARLY enough regulation to discourge moral hazard and market manipulation potential due to the plethora of derivatives out there entirely unlinked from cash settlement values.
