Anshu Jain said nothing. Honouring a long-standing commitment to appear on a panel at a Bloomberg conference in London, the man who co-led Deutsche Bank for three years until July last year, was careful not to mention the gigantic elephant in the room. He was happy to talk about asset valuations, and the impact on deposit taking institutions. And he was only too pleased to wax lyrical on low interest rates causing serious issues for pensions. But discuss the ails of his former employer he did not. Whether by remiss or by Jain’s request, his questioner chose to steer clear of a subject the man who spent 20 years of his career rising up the corporate ladder of Germany’s largest bank would surely have had lots to say on.
