Few banks illustrate the transformative growth of the investment banking industry over the past couple of decades as clearly as Deutsche Bank.

Since the launch of the "Deutsche Bank project" in 1996, the bank has built on the humble foundations of the UK merchant bank Morgan Grenfell and its German treasury and fixed-income business to create the only European investment bank that sits at the very top table of global investment banking - its corporate banking and securities division generates some $18bn in revenues.
