Credit Suisse Group has posted sharply lower results for commodities trading in the third quarter, Reuters reports. The second-largest Swiss bank’s revenues from trading commodity, emission and energy products dropped to $79.2 million, compared to $261.9 million in the second quarter. Concerns about the European debt crisis and a surge in the dollar against the euro have been weighing on commodities.

The decline caused the share of commodities in the group’s overall trading revenues shrink to 4 percent. In the first nine months of 2011, the lender had seen revenues in commodities trading grow 186 percent. The bank is staying the course in its commodities business and will trim only structured long-dated unsecured trades, commodities included.
