Weekly jobless claims rose 36,000 to 447,000, a sign that the unemployment situation remained weak despite retail hirings over the holiday shopping season. A more comprehensive report on unemployment is due out on Friday and economists expect it will be this data which dictates whether the US Federal Reserve Board will cut interest rates for the 12th time in just over a year when it meets again on 30 January. Richard Rippe, economist at Prudential Securities, said the report would be key to discerning the strength of the US economy, which slipped into recession officially in March. 'Economic signs in recent weeks point to stability, but if weakness continues to prevail, the Fed might ease one more time,' he said. 'The labour signs are critical to judging the short-term situation and so the national employment report due tomorrow is critical. We expect a rise in the unemployment rate.'
