Activity in the factory sector weakened significantly last month. Industrial production declined 0.6% (+3.8 y/y) during January following a 0.1% December uptick, revised from +0.3%. A 0.2% rise had been expected in the Action Economics Forecast Survey.

Manufacturing production declined 0.9% (+2.8% y/y) and reversed the December increase. Consumer goods output fell 0.7% (+0.1% y/y), extending the prior month's 0.9% decline. Auto production cratered 8.0% (-0.5% y/y) and reversed two months of strong increase. Appliance & furniture output fell 0.9% (-0.1% y/y) after a 0.6% decline. Working higher, output of computers, video & audio equipment jumped 1.6% (15.8% y/y) following three straight months of strong gain. In the nondurable goods sector, apparel production fell 1.0% (-7.8% y/y), extending a series of large monthly declines. Chemical product production eased 0.1% (+1.2% y/y) but output of paper products rose 0.9% (-4.1% y/y). Production of business equipment fell 1.5% (+3.8% y/y), reversing three straight months of increase. The decline was led by a 5.3% drop (+3.2% y/y) in transit equipment production.
