WASHINGTON - Falling oil prices pushed U.S. consumer prices into their sharpest monthly drop in six years in December, according to government data released Friday.
The Labor Department said its consumer price index fell 0.4% last month, in line with analyst expectations. The CPI declined 0.3% in November.
Energy accounted for all of the decline, the steepest monthly fall since December 2008 amid the financial crisis that triggered the Great Recession.
Energy prices slumped 4.7% from November, reflecting the rapid dive in global crude prices since June that has more than halved their value.
Year-over-year, energy prices dived 10.6%, the steepest slide since 2008.
Gasoline prices plunged 9.4% in December, and have shed 22.4% in the second half of the year.
Food prices rose 0.3% in December, their largest increase since September.
Excluding food and energy prices, the so-called "core" CPI was unchanged.
