The Volcker Rule that prohibits federally insured banks from trading on their own account is likely to become law. It is part of the financial reform bill now making its way through Congress.

She has offered changes which would give banks two years to spin off their derivatives operations, and this would still have to be separate from the commercial bank's operations with separate capital.
