WASHINGTON (AP) - U.S. consumer prices rose 2.4 percent in March from a year earlier, the fastest annual pace in 12 months.
The Labor Department said Wednesday that on a monthly basis, the consumer price index declined 0.1 percent in March. The index's yearly gain, however, suggests that inflation pressures may be picking up.
Excluding the volatile food and energy categories, core prices ticked up 0.2 percent in March and 2.1 percent from a year ago. That was the biggest annual increase for core prices since February 2017.
The gains partly reflect the impact of changes in mobile phone services costs, which fell sharply last March after several carriers introduced unlimited data plans. That drop has lifted year-over-year price changes, boosting the annual gains.
Still, economists said there were signs elsewhere of rising prices. Hotel prices jumped 2.3 percent in March, while rents increased 0.3 percent. Hospital services costs rose 4.9 percent.
"U.S. inflation is warming up rather than heating up," Sal Guatieri, an economist at BMO Capital Markets, said.
The Federal Reserve wants inflation to generally run at about 2 percent, as a hedge against deflation, when prices and wages fall. For most of the past six years, consumer prices have been stuck below that level, according to a separate gauge the Fed monitors.
The consumer price index has averaged just 1.6 percent in the past decade.
