US inflation: Follow the core

US headline inflation was depressed by the plunge in energy prices, but we should be focusing on the core rate, which will be pushed higher by rising labour costs in the months ahead

Goods versus services

Headline inflation for December was, as widely expected, dragged lower by the plunge in gasoline prices seen through the fourth quarter. It fell 0.1% month-on-month in December, leaving the annual rate of US inflation at 1.9%, the lowest since August 2017. However, the core rate, which excludes the volatile food and energy components, has risen 0.2% MoM and 2.2% year-on-year, and remains above the Federal Reserve’s medium-term target.
In terms of the big categories, energy prices fell 3.5% MoM because of those gasoline price declines, which in turn contributed to a 2% MoM drop in transportation costs, while tobacco prices fell 0.4% MoM. Contributing on the upside, food posted a relatively hefty 0.4% MoM rise, while recreation jumped 0.6% MoM (sewing machines up 7.1% MoM and sporting goods up 4%!!) and medical care was up 0.3%.
