Geithner, Member and Overseer of Finance Club

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 Davis, then an assistant Treasury secretary.

The proposal quickly died amid protests that it was politically untenable because it could put taxpayers on the hook for trillions of dollars.

But in the 10 months since then, the government has in many ways embraced his blue-sky prescription. Step by step, through an array of new programs, the Federal Reserve and Treasury have assumed an unprecedented role in the banking system, using unprecedented amounts of taxpayer money, to try to save the nation’s financiers from their own mistakes.
