Five years after the passing of Dodd-Frank, Wall Street is once again thriving-----the banks recorded $19.5bn in totals fees in the first half of 2015, which is the second highest fee total Wall Street firms have collected in a six month period. While the breakdown of its investment banking revenues haven't changed all that much, trading assets have been scaled back as a percentage of total assets at most major banks.
JPMorgan Chase, for instance, generated 26% of its total revenue from trading activities in the first half of 2015. That‘s up from 20% in 2009. Bank of America also gets more of its revenue from trading than before Dodd-Frank, though not much more, 18% vs. 17%. Goldman Sachs was always the Wall Street bank that got the most of its revenue from trading. And there, trading activities do appear to a smaller portion of how Goldman makes its money, but it’s still a lot of what the bank does. In the first half of this year, Goldman made 58% of its revenue from trading activities, down from around 75% in 2009.
