WASHINGTON (AP) — U.S. consumer prices, driven up by rising energy costs, rose moderately in December, closing out a year in which consumer inflation rose at the fastest pace in five years.
The Labor Department reported Wednesday that its consumer price index increased 0.3 percent last month, up from a 0.2 percent gain in November. Energy prices, which have been rebounding, were up 1.5 percent, led by another jump in gasoline pump prices. Food costs were unchanged for the fifth straight month.
For all of 2016, prices were up 2.1 percent, compared to a 0.7 percent rise in 2015. It was the largest annual increase since a 3 percent jump in 2011. Core inflation, which excludes food and energy, was up 0.2 percent in December and 2.2 percent for the year.
After four years of extremely low inflation, prices have begun to accelerate with both overall inflation and core inflation above the 2 percent target set by the Federal Reserve. The low inflation figures had allowed the central bank to keep interest rates at ultra-low levels with its key rate at a record low near zero for seven years.
The Fed has now boosted rates twice in December 2015 and again last month by modest quarter-point moves. Fed officials are projecting that they will boost rates another three times in 2017. Fed officials continue to stress that they believe prices will be rising by modest amounts that will allow them to move interest rates up gradually.
For 2016, food costs actually declined 0.2 percent for the 12 months ending in December while energy costs were up 5.4 percent from a year ago.
Medical care services was one of the fastest rising categories last year, rising by 3.9 percent over the past 12 months.
New car prices were up a slight 0.3 percent but used car prices were down 3.5 percent and clothing prices were down 0.1 percent over the past 12 months.
In addition to a big fall in energy costs, inflation has been kept low in recent years by a rise in the value of the dollar against foreign currencies which makes imports, including clothing imports, cheaper for U.S. consumers.
The Fed has used low interest rates and other measures to provide a boost for the U.S. economy as it struggled to emerge from the worst recession since the 1930s.
