Wall Street advanced, with gains tempered by expectations that Congress will not act to stop automatic federal spending cuts that are widely expected to put the brakes on the pace of expansion in the world's largest economy.
The International Monetary Fund warned it will downgrade its economic forecast for the US if US$85 billion of schedule federal spending cuts take effect on March 1.
If all cuts go ahead, the IMF would lower its current estimate for a 2 per cent expansion for US gross domestic product this year by at least 0.5 per cent, IMF spokesman William Murray told reporters at a news briefing. Global growth also would be hit.
In afternoon trading in New York, the Dow Jones Industrial Average rose 0.14 per cent, the Standard & Poor's 500 Index gained 0.18 per cent, while the Nasdaq Composite Index climbed 0.37 per cent.
Expectations of a slowdown in the pace of growth buoyed US Treasuries.
