Wall Street declined as US House Speaker John Boehner renewed concern about the lack of progress in talks aimed at preventing US$600 billion in tax increases and spending cuts taking effect on January 1.
"Unfortunately, the White House is so unserious about cutting spending that it appears willing to slow-walk our economy right up to the 'fiscal cliff,'" Boehner told a news conference.
Failing to reach a deal to avoid the so-called fiscal cliff could push the world's largest economy into recession next year, the non-partisan Congressional budget office has forecast. Further evidence of the glacial pace of negotiations has increased uncertainty about the outlook for the economy and corporate profits.
"There's a lot of confusion. Nobody knows what's going to happen with the cliff," Tom Schrader, managing director of US equity trading at Stifel Nicolaus Capital Markets in Baltimore, told Reuters.
In afternoon trading in New York, the Dow Jones Industrial Average fell 0.44 per cent, the Standard & Poor's 500 Index shed 0.56 per cent, while the Nasdaq Composite Index dropped 0.75 per cent.
