U.S. producer prices shot up a hefty 0.8 percent last month, the biggest jump since March 2003, as prices for food and energy surged, the Labor Department said Thursday.

In another sign that the economy continues to improve, claims for unemployment benefits fell last week, coming in below estimates.

In other news, influential bond fund manager Bill Gross of PIMCO told the Financial Times that he's worried about the outlook for the global economy.

"Too much debt, geopolitical risk and several bubbles have created a very unstable environment which can turn any minute," Gross was quoted as saying. "More than any point in the past 20 or 30 years, there's potential for a reversal."
