BNP Paribas SA is finding it harder to evade the trading slump that’s engulfing rivals.
After emerging almost unscathed from the period of low volatility that weighed down Wall Street firms and European investment banks earlier this year, the Paris-based lender posted a bigger-than-expected 17 percent drop in trading revenue in the third quarter, or 15 percent on a constant-currency basis. That was a better performance than Deutsche Bank AG and Barclays Plc, but was in line with the average decline at its main U.S. peers.
