Deutsche Bank has endured a sluggish first quarter, and failed to cash in on improved bond trading conditions enjoyed by its US investment banking rivals and Credit Suisse, reports the Wall Street Journal. Fixed-income trading revenues at major US investment banks were up by 24 per cent in the first quarter of 2017 versus the same period last year; Credit Suisse's trading division rose 30 per cent. In contrast, as WSJ points out, Deutsche quit the mortgage-bond trading business last year, missing the rebound, leaving the German group's bond trading just 11 per cent higher than for the comparable period in 2016.
