proprietary trading or principal trading account only small pct of revenue even for GS/MS. Traditional bank has much smaller proprietary trading group. However, the risk allocated to that group is much higher that others. We should expect proprietary trading group has larger revenue swing that others. It may not be a bad thing to restrict proprietary trading. Certainly if it is totally banned, it will affect the revenue of GS/MS/BAC(ML). BTW, I don't think the bill can be passed.
