Last June, with a financial hurricane gathering force, Treasury Secretary Henry M. Paulson Jr. convened the nation's economic stewards for a brainstorming session. What emergency powers might the government want at its disposal to confront the crisis? he asked.
Timothy F. Geithner, who as president of the New York Federal Reserve Bank oversaw many of the nation's most powerful financial institutions, stunned the group with the audacity of his answer. He proposed asking Congress to give the president broad power to guarantee all the debt in the banking system, according to two participants, including Michele A. Smith, then an assistant Treasury secretary.
