WASHINGTON, D.C. — U.S. manufacturers showed firm signs of life in October after a mid-year slowdown, but overall industrial output was lower due to the energy sector slump, according to Federal Reserve data released Tuesday.

The Fed’s industrial production index dropped 0.2% in October after a 0.2% drop in September, and showed a bare 0.3% gain from a year ago, mainly due to the sharp contraction in the oil and coal mining sectors, related to the plunge in fuel prices. Utility sector output was also lower, in part because of a very mild autumn in much of the United States, slowing demand.

“Manufacturing production, however, posted 0.4% growth in October and the change in production was revised up for the months of August and June,” MAPI Foundation chief economist Daniel J. Meckstroth said. “Utility production fell 2.5% and mining industry production contracted 1.5% in October.

“The October report is a positive statement about manufacturing growth,” he said, noting that production is up in 13 or the 20 major manufacturing industries, with a 14th flat. “A recent major driver of growth is the ramping up of the construction supply chain; both residential and commercial and industrial construction are strong, and public works construction is growing at a modest pace.”

Manufacturing production could have been even better if not for a steep decline in energy production, with energy consumer products, commercial products and converted fuel down 1.7% in October.

“The headwinds in manufacturing — rising trade deficits, a decline in the supply chain of oil country goods, and high inventories — are at their worst, so the good news that manufacturing did post solid growth in October bodes well for going into 2016,” Meckstroth said.

The manufacturing sector is up 1.9% over the past 12 months. There was strength last month in automobile output, business supplies and construction materials, all important to stronger overall growth in the U.S. economy.

Consumer goods, another key category, was down slightly in the month, though 3.5% higher for the year, with durable goods production up 0.49%.

That durable goods number suggests “that record trade deficits are suppressing production,” said Alan Tonelson, who covers manufacturing and broader economic issues. “In this vein, real manufacturing output still hasn’t recouped all of its recessionary losses, with real production remaining 1.23% below pre-downturn highs. Nonetheless, October’s year-on-year non-durables after-inflation production advance continued a recent trend of annual growth pickup which actually exceeds the rates achieved by durable goods.”
