A member of the bank's board since 2010 as the head of the Corporate and Investment Bank, Jain took over as the co-CEO of Deutsche Bank on June 1, 2012. As the head of the Corporate and Investment Bank he was responsible for Deutsche Bank's global trading, sales and finance. He was promoted to the top position of Deutsche Bank after the Corporate and Investment Bank contributed to
86 per cent of the bank's profits in 2010. In April 2010, the net revenue of Deutsche Bank in the first quarter stood at 9 billion euro, of which Corporate and Investment Bank contributed 6.6 billion euros. Deutsche Bank's shareholders were apprehensive of promoting Jain as the co-CEO, who had little knowledge of German, but he shocked everyone when he fluently spoke the language at its general meeting in May 2013.
