FRANKFURT, Germany (AP) — Deutsche Bank’s restructuring is showing results. The bank had its best quarter in seven years. CEO Christian Sewing says Germany’s largest bank is benefitting from ongoing cost discipline. On top of that, an improving economy means the bank is seeing fewer losses on loans that aren’t repaid by businesses. Deutsche Bank has been going through a years-long restructuring by dumping less-profitable business areas and cutting its workforce. The pre-tax profit of 1.6 billion euros was the best since the first quarter of 2014.
