The Industrial Materials Price Index from the Foundation for International Business and Economic Research (FIBER) declined 3.7% last month. It has fallen for five straight weeks. Despite the declines, the index has risen by 6.5% y/y.

The recent decline was led by an 8.4% m/m drop in metals prices, which remained up 3.8% y/y. Leading the decline was a 16.9% fall (-7.6% y/y) in zinc prices. Copper scrap prices were off 11.7% m/m (+3.1% y/y) and lead prices fell 10.9% in four weeks (-5.8% y/y). Aluminum prices weakened 5.0% m/m, but rose 9.9% y/y. To the supside, steel scrap prices improved 0.9% in the last month (29.0% y/y). Prices in the miscellaneous group fell 5.2% during the last four weeks (+5.2% y/y). Framing lumber prices declined 6.8% last month, up 29.4% y/y. Prices for structural panels were off 9.2% during the last four weeks, but rose 20.1% y/y during the last year. Natural rubber prices fell 2.9% in four weeks and were down 8.7% in the last year. Offsetting the declines last month was a 1.3% price rise (18.8% y/y) in the crude oil & benzene sector. Crude oil prices rose 5.1% during the last four weeks, but in the last two fell 6.7%, to an average $68.95 per barrel. Prices remained up by roughly one-half y/y. Offsetting that rise were benzene prices which fell 2.9% (+13.4% y/y) in the last four weeks. In the textile group, prices overall improved 0.4% last month (3.9% y/y). Cotton prices increased 2.2% over the last month (29.1% y/y) while burlap prices rose 0.9% m/m, but were down 2.1% during the past year.

Renewed strength in prices overall may be coming. The consensus forecast for industrial output from the National Association for Business Economics (NABE) calls for a 3.8% rise during all of 2018 and 2.8% growth in 2019. During the last ten years, there has been 50% correlation between the three-month change in prices and the change in U.S. industrial output. In addition, factory sector production in the European Union and Japan continues to improve.
