Chairman, HSBC

With operations from Shanghai to San Francisco, London-based HSBC (HBC)—Europe's largest bank by market capitalization—benefited from its global footprint in fighting off the financial crisis. Like many of his peers, Green is wary of plans to increase banking regulation, though he told a panel at Davos that "the devil is in the details" of plans under way to limit banks' trading activity. In a later interview with Bloomberg, Green urged the U.S. not to go it alone on new banking regulations, preferring that measures affecting the range of banking activities should be considered on an international level.
