US consumer prices gain slightly in Dec.

WASHINGTON — US consumer prices rose slightly in December even as households paid more for health care, and monthly underlying inflation slowed, supporting the Federal Reserve’s desire to keep interest rates unchanged at least through this year.

The weak inflation report from the Labor Department on Tuesday came on the heels of data last week showing a moderation in job growth in December. Economists said these developments were flagging a sharp slowdown in domestic demand. Though the economy appears to have maintained a steady pace of growth in the fourth quarter, it was likely supported by falling imports.

“This is giving rise to the fear that maybe economic demand is showing early signs of hitting a new soft patch for growth that will carry into the first quarter of 2020,” said Chris Rupkey, chief economist at MUFG in New York. “The Federal Reserve is on the sidelines this year, but that could swiftly change if overall economic demand weakens and inflation shows little sign of returning to target.”

The Labor Department said its consumer price index (CPI) increased 0.2% last month after climbing 0.3% in November. The monthly increase in the CPI has been slowing since jumping 0.4% in October. In the 12 months through December, the CPI rose 2.3%. That was the largest increase since October 2018 and followed a 2.1% gain year-on-year in November.

The CPI accelerated 2.3% in 2019, the largest rise since 2011, after increasing 1.9% in 2018. Economists polled by Reuters had forecast the CPI would rise 0.3% in December and advance 2.3% on a yearon-year basis.

Excluding the volatile food and energy components, the CPI edged up 0.1% after climbing 0.2% in November. The so-called core CPI was up by an unrounded 0.1133% last month compared to 0.2298% in November.

Underlying inflation in December was held back by declines in the costs of used cars and trucks, airline tickets and household furnishing and operations, which offset increases in the prices of health care, apparel, new motor vehicles, recreation and motor vehicle insurance.

In the 12 months through December, the core CPI increased 2.3%, the largest gain since October 2018, after rising 2.3% in November. For all of 2019, the core CPI gained 2.3% after increasing 2.2% in 2018.

The dollar was little changed against a basket of currencies as investors awaited the signing on Wednesday of a preliminary trade deal between the United States and China, a first step toward diffusing an 18-month trade war. US Treasury prices rose. Stocks on Wall Street were mixed.

The Fed tracks the core personal consumption expenditures (PCE) price index for its 2.0% inflation target. The core PCE price index rose 1.6% on a year-on-year basis in November. It undershot its target in the first 11 months of 2019. PCE price data for December will be published later this month.

The US central bank last month left interest rates steady and signaled monetary policy could remain on hold this year after it reduced borrowing costs three times in 2019. —
