Falling gasoline prices contributed to cooler-than-expected inflation in February.
The gasoline index declined 1% last month, compared to a rise of 1.8% in the prior month, according to data from the Bureau of Labor Statistics released on Wednesday.
On an annualized basis gasoline prices decreased 3.1%.
On Wednesday, the national price of gasoline hovered at $3.08 per gallon, about $0.07 lower than a month ago, according to AAA data.
Despite the decrease in gas prices, the energy index rose 0.2% over the month as electricity and natural gas prices rose.
While oil prices have declined year to date, natural gas has soared amid a colder-than-expected winter and increasing exports.
