FT.com / Comment / Analysis - The game changer:
What about credit default swaps? Here I take a more radical view than most people. The prevailing view is that they ought to be traded on regulated exchanges. I believe they are toxic and should be used only by prescription. They could be used to insure actual bonds but – in light of their asymmetric character – not to speculate against countries or companies.
CDS are not, however, the only synthetic financial instruments that have proved toxic. The same applies to the slicing and dicing of collateralised debt obligations and to the portfolio insurance contracts that caused the stock market crash of 1987, to mention only two that have done a lot of damage. The issuance of stock is closely regulated by authorities such as the Securities and Exchange Commission; why not the issuance of derivatives and other synthetic instruments? The role of reflexivity and the asymmetries identified earlier ought to prompt a rejection of the efficient market hypothesis and a thorough reconsideration of the regulatory regime.
