The number of newly laid off Americans signing up for jobless benefits last week unexpectedly climbed to its highest point in more than six years as the faltering US economy forced companies to cut back. The Labor Department reported Thursday that new applications filed for unemployment insurance rose by a seasonally adjusted 7,000 to 455,000 for the week ending Aug. 2. The increase left claims at their highest level since late March 2002. A program to locate people eligible for jobless benefits played a role in the increase, a Labor Department analyst said. However, the analyst couldn't say how much of a role. The latest snapshot of layoff filings was worse than analysts expected. They were forecasting new claims to drop to around 430,000. The data disappointed Wall Street and the White House. The Dow Jones industrials fell more than 100 points in morning trading. “The job market isn't strong right now as we work through the downturn in housing and high energy prices. We would like to see more job creation,” said White House spokesman Tony Fratto. He credited the government's stimulus program as a helpful cushion. With layoffs rising and new jobs harder to find, there's growing worry that consumers will retrench later this year as the fortifying impact of the government's tax rebates disappear - spelling more trouble for the economy. Wal-Mart, the world's largest retailer, and Costco Wholesale Corp. reported solid sales for July. However, Wal-Mart's sales came in a bit below Wall Street forecasts. The company noted that shoppers are increasingly running out of money and projected that sales would slow in August as rebate checks dry up. Many apparel stores including Limited Brands Inc., Abercrombie and amp; Fitch Co. and Pacific Sunwear of California remained in a malaise. On the layoffs front, the new filings for unemployment benefits were distorted somewhat by the outreach program to notify people that they could qualify for additional benefits under a new law. When people went to state claims offices to apply for these extended benefits, state officials discovered that some were eligible for - but haven't filed for - their initial unemployment benefits, the Labor Department analyst said. Meanwhile, the four-week moving average of claims, which smooth out weekly fluctuations, rose to 419,500 last week, the highest since mid-July 2003. The number of people continuing to collect unemployment benefits went up by 31,000 to 3.3 million for the week ending July 26, the most recent period for which that information is available. That was the highest since early December 2003. Among the companies announcing job cuts in late July or early August were: General Motors Corp., Weyerhaeuser Co., and Starbucks Corp. Bennigan's restaurants owned by Metromedia Restaurant Group, are closing, driving more people to unemployment lines.
