CME Group, the world’s biggest futures exchange, reported on Thursday that its profits in the third quarter fell by one-fifth, as the hangover from the financial crisis continued to impact trading volumes and regulatory uncertainty weighs on the industry.

The company said that, excluding extraordinary charges, its net income in the quarter was $223m or $3.35 per share, down from $278m or $4.13 per share in the same period last year but in line with analysts’ expectations.
