I think they will do nothing, and when it hits the fan the political grandstanding for reform will be in this area. They will claim they had no real idea of the depth of the problem, and now they have identified it and fixed it. They will pick out a couple of high profile companies and execs and bring charges on them just like they did with equities.
A few will go to jail, many will be fined. Then we will move on after all the political points have been tallied. Most of the “reforms” they have done in the financial markets are complete window dressing and have really accomplished nothing. A prime example was blaming the buy and sell programs for stock crashes, they had nothing to do with it. However, the average person was sold this bill of goods and felt better when something was “done” about it.
