Ten years after Lehman Brothers collapsed, former Deutsche Bank Chief Executive Officer Josef Ackermann says European banks are in a position of inferiority compared to their U.S. peers, and have no choice but to pursue cross-border mergers in an era of Donald Trump’s “America First.” Josef Ackermann ran Deutsche Bank for 10 years until 2012. He spoke in an interview with Bloomberg Television's Guy Johnson, recorded Sept. 3 in Zurich. (Source: Bloomberg)
