The CFTC may break with other agencies on a much-anticipated plan to ban most proprietary trading by banks, and could opt to put forth a slightly different version of the Volcker rule. An independent approach from the commission could raise questions about coordination and embolden banks to challenge the Volcker rule, although the agency is not believed to play a central role in implementing it. CFTC chief Gary Gensler is taking a "wait and see" approach to the rule. Both the FDIC and the SEC are scheduled to vote this week on the Volcker rule, which has already forced banks to scale back previously lucrative proprietary trading. The decision comes as a bit of a surprise because in the past the CFTC worked with the regulators on rules. A source familiar with the CFTC's thinking said Gensler is waiting to see how Congressional lawmakers react to the Volcker rule proposal before deciding how to move forward. A person familiar with the rulemaking process said the CFTC is only tangentially mentioned in the Volcker rule, and it is unclear what the implications would be if the CFTC takes an alternative approach.
