don't think it's affected. the motion is not targeting banks trading on inside information, but banks taking excessive risks where profits are for the bankers but losses are for the public, e.g., it's a no brainer for GS to take oversized risk in the last year...
banks, at the end of the day, are intermediaries. there are risks associated with the role as an intermediary as well, so the risk management function will always be there...maybe just one less thing to consider.
