Below is Secretary Geithner's opinion regarding exchange based trading vs. ISDA/OTC markets:
Transparency will lower costs for users of derivatives, such as industrial or agriculture companies, allowing them to more effectively manage their risk. It will enable regulators to more effectively monitor risks of all significant derivatives players and financial institutions, and prevent fraud, manipulation and abuse. And by bringing standardized derivatives into central clearing houses and trading facilities, the Senate bill would reduce the risk that the derivatives market will again threaten the entire financial system.
