US consumer prices post biggest rise in nearly 4 years

WASHINGTON (AP) - U.S. consumer prices rose in January at the fastest pace in nearly four years, strengthening the case for the Federal Reserve to raise interest rates this year.

The Labor Department said Wednesday consumer prices rose 0.6 percent last month, the most since February 2013, and twice what economists were expecting. A 7.8 percent jump in gasoline prices accounted for nearly half the increase.

Stripping out food and energy prices, which tend to fluctuate sharply from month to month, so-called core consumer inflation rose 0.3 percent in January. Fed policymakers monitor core measures of inflation especially closely.

Food prices rose in January for the first time in seven months. Grocery prices were unchanged, but the cost of eating out rose 0.4 percent. The price of clothing, new cars, auto insurance and air fares all rose by 0.8 percent or more in January.

Overall, consumer prices rose 2.5 percent from a year earlier, most since March 2012. Core inflation rose 2.3 percent over the last 12 months.

After remaining low in the aftermath of the 2007-2009 Great Recession, inflation is running above the Fed's 2 percent annual target.
