The Industrial Product Price Index (IPPI) rose 0.4% in September, led by higher prices for energy and petroleum products, as well as motorized and recreational vehicles. The Raw Materials Price Index (RMPI) edged down 0.1%, as lower prices for animals and animal products were largely offset by higher prices for crude energy products.

The IPPI rose 0.4% in September, after falling 0.4% in August. Of the 21 major commodity groups, 15 were up, 5 were down, and 1 was unchanged.

Higher prices for energy and petroleum products (+0.9%) in September largely contributed to the increase in the IPPI. The gain in this commodity group was primarily attributable to higher prices for light fuel oils (+2.6%), motor gasoline (+0.7%), and, to a lesser extent, heavy fuel oils (+3.3%), jet fuel (+3.5%), and diesel fuel (+0.9%). Moderating the rise in energy and petroleum products were lower prices for asphalt (except natural) (-6.3%). The IPPI excluding energy and petroleum products rose 0.3%.
