WASHINGTON, US - PRESIDENT Barack Obama's administration is 'incredibly confident' the US economy will rebound within a year, a top adviser said on Sunday, before a critical week in efforts to flesh out and sell its recovery agenda.

'We will be seeing signs the economy is turning around,' Christina Romer, head of the White House Council of Economic Advisers, told the 'Fox News Sunday' programme.

On CNN's 'State of the Union' show, Ms Romer said she had 'every expectation, as do private forecasters, that we will bottom out this year and actually be growing again by the end of the year.' Mr Obama's steps to reverse a deep recession and restructure the ailing US financial system have global implications as he prepares to meet leaders of major developed and developing nations at a Group of 20 summit in early April.

But his reform plans and the vast spending envisioned to reboot the world's largest economy and purge at least US$1 trillion (S$1.52 trillion) in 'toxic' assets from banks face steep resistance from some in Congress and corporate boardrooms.

In a key part of the agenda, Treasury Secretary Timothy Geithner is due to unveil long-awaited details of his bank bailout plan at 8.45am (8.45pm Singapore time) on Monday.

The Treasury Department is expected to brief private capital groups later on Sunday about incentives to get them involved in the plan to buy up banks' troubled assets, according to a source familiar with the matter.

Mr Geithner is also due to to expand on proposals for financial regulatory reform at a congressional hearing on Thursday.

One aim of the three-part strategy to cleanse the financial system will be to entice private investors with abundant loans and generous terms to buy bad mortgages and other toxic assets, a source familiar with the plan told Reuters on Saturday.

Mr Obama, a Democrat whose high approval ratings are being tested in his third month as president as public anger rages over big bonuses at bailed-out financial firms, will discuss his recovery efforts in a prime-time news conference on Tuesday. -- REUTERS
