Dresdner Bank's trading revenues tripled in the second quarter, driving operating profits up more than half to €319m ($408m). The performance helped the bank more than double profits during the first six months of the year.

The figures, which include revenues at the rebranded Dresdner Kleinwort investment bank, were revealed in today's second-quarter results for parent group Allianz, the German insurer. They were published a week early.
