Prices fell in December, indicating U.S. businesses are not passing on the costs of tariffs to consumers. The Labor Department said Wednesday that its Producer Price Index fell in December. Compared with the month, prices were down 0.2 percent. Economists had forecast a slight price gain for the month. The index for final demand goods–which are those most likely to translate into consumer prices–moved down 0.4 percent in December, the same as in November. Food prices rose. Absent food and energy, final demand prices rose 0.2 percent. One reason for the very tame inflation data is the steep drop in the price of oil. Absent the volatile food and energy categories, prices of goods fell just 0.1 percent. Gasoline prices fell 13.1 percent in December and overall final demand energy prices dropped 5.4 percent. Inflationary pressures have been easing. Producer prices advanced 0.1 percent in November and 0.6 percent in October. On an unadjusted basis, prices were up 2.5 percent compared with December 2017. That is a move down from the year-over-year price gain of 2.7 percent recorded in November and it matches what was recorded in December of last year. In other words, the December price gains were no higher than what was recorded before the Trump administration’s tariffs on steel, aluminum, and China imports were imposed. Price levels have held remarkably steady on most categories of goods in 2018, defying predictions that American households would be squeezed by tariffs on steel, aluminum, and around $250 billion of goods made in China. On Monday, China’s commerce ministry announced that it ran a trade surplus with the U.S. last year that was the highest on record. The U.S. collected around $8 billion in tariffs in the October through December period, around 83 percent more than the period a year prior. Price increases are more noticeable lower down in the production chain of materials and components that go into making final goods, although recent data show that rise has moderated or reversed. Steel mill products, for example, fell 0.6 percent for the month but were up 18.5 compared with a year ago. Prices of materials used in durables manufacturing—which are those most likely to be affected by the tariffs on steel and aluminum—fell 0.2 percent on a monthly basis, the third consecutive monthly declined.
