Donald Trump’s successful insurgent bid for the White House promised to upend a global power structure that benefited large corporations. Now, several Wall Street financiers and other successful business leaders could be in line to run top posts in his presidential administration.

People close to Trump have said he is considering Steven Mnuchin, a former Goldman Sachs banker who became his national campaign finance chairman in May, as his pick for Treasury secretary. If tapped for the job, Mnuchin would become the third Goldman alumnus in the last 20 years to head the Treasury, following Robert Rubin and Hank Paulson, who both served as the bank's chief executive.
