Deutsche Bank bounced back to profit in the third quarter, as it reduced reserves set aside for investor lawsuits over its Postbank division while its global investment bank fired on all cylinders. A 15-quarter profit streak at Germany's largest lender was interrupted in the second quarter after it made a large provision for the lawsuits.

The partial release of 440 million euros of litigation provisions in the third quarter helped boost profit, Deutsche Bank said.

Germany’s largest lender reported a better-than-expected rise in its third-quarter profit on growth in its investment-banking division and the partial release of provisions linked to litigation over its Postbank acquisition.
