The Industrial Materials Price Index from the Foundation for International Business and Economic Research (FIBER) declined 1.3% during the last four weeks and extended the decline in prices since the peak four months ago. The decline left the index down 4.1% during the last year. During the last ten years, there has been a 66% correlation between the y/y change in industrial commodity prices and the y/y change in factory sector production.

Recent weakness in commodity prices was led by a 7.6% m/m decline in prices  (-13.2% y/y) in the miscellaneous group. Leading the downdraft were framing lumber prices which fell 15.4% m/m. Prices for structural panels declined 10.1% m/m and 20.3% y/y. Natural rubber prices, however, reversed earlier declines with a 2.2% four-week rise (-0.3% y/y). Prices in the textile group dipped again with a 0.3% four-week decline (+1.2% y/y) paced by a 1.9% drop in cotton prices (+13.2% y/y). Burlap prices (used for rope & nets) were little changed (-2.4% y/y).

Metals prices worked 4.4% higher during the last four weeks (-6.5% y/y). The gain was led by zinc prices which increased 12.8% m/m, but fell 18.5% y/y. Steel scrap prices rose 8.1% m/m and by roughly one quarter y/y. Copper scrap prices increased 4.3% m/m but fell 10.4% y/y. The cost of aluminum rose 1.1% m/m although it declined 4.8% y/y. Lead prices improved 0.4% m/m (-18.9% y/y). Also increasing were prices in the crude oil & benzene group by 0.7% m/m and 13.4% y/y. Crude oil prices gained 1.0% during the last four weeks and roughly one-third y/y to an average $70.73 per barrel, the highest price since November 2014. Accompanying the rise in crude oil prices were benzene costs which gained 1.5% m/m (4.5% y/y).

Improvement in prices overall may be coming. The consensus forecast from the National Association for Business Economics (NABE) calls for a 3.8% rise in industrial output during all of 2018 and 2.8% growth in 2019. During the last ten years, there has been a 66% correlation between the y/y change in industrial commodity prices and the y/y change in factory sector output. In addition, factory sector production in the European Union and Japan continues to improve.
