“What an era in which we live where a serious question can be asked whether $1.5 trillion is enough,” he said Tuesday after a reporter asked if $1.5 trillion would solve our economic woes.

The choice of Geithner may have boosted confidence on Wall Street. In the last hour of trading, stocks shot up and the Dow Jones Industrial Average was up nearly 500 points at its close.

The Washington Post has this to say about Geithner:

Geithner, who is 47, is most closely aligned with Clinton-era economics, having previously worked at Treasury under Clinton secretaries Bob Rubin and Larry Summers.

But he is thought of as an economic centrist. [...] Prior to Treasury, Geithner worked at the IMF and with Henry Kissinger at his consulting firm.

And here’s an excellent Post piece describing how Geithner’s partnership with Paulson and Bernanke developed, and how the three men make on-the-fly decisions that affect the entire world’s economy.

As the financial crisis began in August 2007, the phone calls became more frequent — often quick, and unplanned. The three developed a Socratic style; one man would present an idea, and the others would challenge it, consider its flaws and ultimately find ways to tweak it.

Within the fraternity, the man who takes the lead depends on which agency is primarily responsible for the matter at hand.

When Geithner engineered the rescue of failing investment bank Bear Stearns in the middle of a cold March night, he had Paulson and Bernanke on the phone to get their input and blessing.

Paulson took the lead on the government takeover of Fannie Mae and Freddie Mac, but Bernanke advised him closely, and Geithner played a supporting role in calculating the impact on the financial markets.

Obama is expected to formally announce Geithner’s nomination Monday. NBC is reporting that Obama also will probably name New Mexico Governor Bill Richardson as Commerce secretary. And the New York Times reported today that Sen. Hillary Clinton, D-N.Y., will accept Obama’s offer to be secretary of state.
