By PAUL WISEMANWASHINGTON (AP) — Rising energy costs pushed consumer prices higher in October, but overall inflation remains tame. The Labor Department said Thursday that its consumer price index rose 0.4 percent last month, the most since April and up from a 0.3 percent increase in September. Over the past year, consumer prices are up 1.6 percent — below the Federal Reserve's 2 percent annual inflation target. Despite low inflation, the Fed has hinted that it might resume raising U.S. interest rate at its next meeting Dec. 13-14. The Fed raised rates nearly a year ago for the first time since 2006 and was widely expected to follow up with several more hikes in 2016. But it held off as the U.S. economy stalled from late 2015 through mid-2016 and the global economy continued to look weak. Energy prices rose 3.5 percent last month, led by a 7 percent hike in gasoline prices. The cost of shelter rose 0.4 percent on a 1.8 percent rise in hotel rates. Food prices were unchanged for the fourth straight month. Medical care prices were also flat. Core inflation, which strips out volatile food and energy costs, rose a modest 0.1 percent last month and is up 2.1 percent over the past year. A steady uptick in consumer prices, along with President-elect Donald Trump's plans to cut taxes and increases infrastructure spending, mean "inflation risks for the foreseeable future are to the upside," Ian Shepherdson, chief economist at Pantheon Macroeconomics, wrote in a research report.
