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.

Germany's largest lender had posted a 143-million-euro loss in the second quarter, at the time announcing it would not embark on a second share buyback program this year and factoring in a provision for its long-running lawsuit over its acquisition of its Postbank division.

Germany's biggest lender Deutsche Bank on Wednesday reported a sharp jump in third-quarter profits, boosted by the settlement of investor lawsuits related to a troubled takeover.

Deutsche Bank has raised its forecast for bad loans against the backdrop of a weak German economy, as the bank returned to profit in the third quarter, boosted by investment banking and a cut in reserves for Postbank lawsuits.

Deutsche Bank AG plans to restart share buybacks after revenue at the investment bank rose and the lender largely settled a legacy dispute.

Deutsche Bank reports a Q3 net profit of €1.46 billion, beating forecasts and reversing a previous quarter loss. Revenue reached €7.5 billion, with the bank also releasing €440 million in litigation provisions.

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