Washington  - President-elect Barack Obama unveiled the key leaders of his economic policy on Monday, naming Timothy Geithner to head the US Treasury and Larry Summers as his top White House economic advisor.

Geithner, currently the president of the Federal Reserve Bank of New York, will be charged with returning stability to the US financial system. He has already worked closely with current Treasury Secretary Henry Paulson and Fed Chairman Ben Bernanke since the financial crisis spiralled out of control in September.

Summers will become director of the White House National Economic Council, making him Obama's chief economic advisor. Summers is a respected economic voice who served as Treasury secretary in the latter years of former president Bill Clinton's administration.

"I've sought leaders who could offer both sound judgement and fresh thinking," Obama said in a press conference in Chicago.

Obama said the new team would begin work immediately on a new fiscal stimulus package to revive the US economy, which is likely headed into a recession. (dpa)
