Worries the U.S. economic recovery

The U.S. federal government debt investors worried about the market. December 2010 Congress passed tax cuts Obama administration, the U.S. national debt since the collapse of Lehman Brothers suffered the biggest sell-off, the incentive of investors lack confidence in the U.S. government deficit under control. Well-known international rating agency Moody's warned that if the U.S. government deficit and debt levels continued to rise significantly, will be considered in the next 12 to 18 months down the United States sovereign credit rating.

Followed by employment difficult to see improvement. Last November the U.S. unemployment rate rose to 9.8%, the Fed believe that the unemployment rate will remain high in 2011, the year the unemployment rate is still likely to exceed 9%. U.S. unemployment rate will remain in the 80 highest level since early. Since December 2007 the United States since the recession began, about 800 million people lost their jobs.

To make matters worse, the U.S. housing market may continue to slump. Analysts had predicted that in 2010 the U.S. housing market in a modest improvement, but now that the 2011 U.S. house prices will fall as much as 10%. David Wyss, chief economist at Standard & Poor's, said, thought the housing market hit bottom in 2010, but now looks "have to wait another year."

New York University economics professor Nouriel Roubini predicted early December last year, will now double-dip recession in the U.S. housing market, the problem will spread even to the "high end" market. He said the U.S. property market is definitely "is entering the second bottom", the banking industry may face a second wave of huge property losses.

Saddled with high debt, high unemployment, the real estate downturn that "two high and one low," the heavy burden the U.S. economy can hardly be optimistic about the prospects for recovery.
