Wall Street always knew financial reform was coming. The big banks never really thought there was a chance of killing it, not that they really tried to. In fact, once the effort moved into 2009, they wanted it over sooner rather than later. The longer the process dragged out, the greater the chance of something crazy popping up and the more political and profit damage they took. For instance: The “break up the bank” movement was almost successful. As it is, the Volcker rules and derivatives reform may end up far tougher than their worst-case scenario.
