Will these joint meetings between the SEC and CFTC involve Treasury Secretary Tim Geithner's proposed plan to monitor derivatives transactions more closely, particularly with respect to potential margin requirements on all derivatives to prevent another AIG-style collapse? I agree in principle with Mr. Geithner's plan with respect to derivatives monitoring, but I believe that the actual enforcement of such policy would be better implemented through the SEC or CFTC, not the Treasury.
