WASHINGTON—U. S. industrial output declined last month amid a big drop in auto production, a reminder of the factory sector’s lackluster performance in recent months.
Industrial production, a measure of everything made by factories, mines and utilities, fell a seasonally adjusted 0.4% in May, the Federal Reserve said Wednesday. Economists surveyed by The Wall Street Journal had forecast a 0.3% decrease.
The move largely reflected a fall in output at auto factories and electric utilities.
Overall manufacturing output slid 0.4% in May, led by a 4.2% drop in production of motor vehicles and parts.
Utilities output was down 1.0% from the prior month.
Mining production rose 0.2%, the sector’s first increase since August 2015. The increase followed a rebound in coal mining while oil and gas extraction was little changed. The sector had been in free fall amid a nearly two-year drop in commodity prices, which led energy companies to slash investment.
Capacity use, a measure of how much industries are making as a share of potential output, fell 0.4 percentage point to 74.9%. The rate is 5.1 percentage points below the historical average, suggesting there is still ample slack across the economy.
Overall industrial production was down 1.4% in the 12 months through May. Manufacturing output is 0.1% below its year-ago level. Utility output is down 0.8% and mining output has plunged 11.5%.
Overall industrial production peaked in November 2014 but has failed to regain that level as the mining sector collapsed and manufacturing broadly leveled off.
Factories have been constrained by a strong dollar and weak overseas demand for many products. Autos had been a bright spot, and May’s decline could quickly be reversed.
