U.S. factory production declined unexpectedly in August, according to data released by the Federal Reserve, marking the end of a seven-month streak of growth. The 0.3% drop contrasted with economists' forecasts for a modest 0.3% increase, reflecting growing headwinds from higher energy costs and rising interest rates.
The manufacturing sector, which accounts for approximately 9.4% of the U.S. economy, had experienced gains earlier this year as companies accelerated orders amid geopolitical tensions, notably the ongoing conflict involving Israel and Iran, which has kept oil prices above $100 per barrel. However, those factors now appear to be weighing on industrial output.
Production of durable goods fell 0.5% in August, with motor vehicles and parts output declining 1.2%, marking a second consecutive monthly decrease. Output of computers and peripheral equipment declined 1.4%, although this category remained up 5.5% compared to a year earlier. Communications equipment production rose 0.8%, while semiconductor and related electronic component output dipped marginally by 0.1% but showed a robust 12.4% year-over-year increase.
Economists highlighted that ongoing investment in artificial intelligence infrastructure has provided some support to manufacturing activity, partially offsetting the impact of earlier import tariffs. Bernard Yaros, lead U.S. economist at Oxford Economics, noted that AI-related spending and increased defense expenditures could sustain growth, despite recent rises in longer-term Treasury yields and the Federal Reserve’s latest interest rate hike.
The Federal Reserve raised its benchmark overnight interest rate by 25 basis points to a range of 3.75% to 4.00% earlier in the week, its first increase in three years, signaling potential further tightening to manage inflation. Higher borrowing costs, combined with elevated energy prices, are expected to moderate factory activity in the coming months.
Samuel Tombs, chief U.S. economist at Pantheon Macroeconomics, projected that manufacturing output might show slight increases but at a slower pace than seen in the year's first half, cautioning that demand could soften as producers pass on energy cost increases to consumers.
Non-durable goods production was unchanged after a 0.4% decline in July. Gains at textile mills and in apparel and leather products were offset by declines in plastics, rubber goods, petroleum, and coal production. Mining production grew modestly by 0.1%, with oil and gas well drilling rising 0.9%. Utilities output rose notably by 1.8%.
Some analysts expressed concern that continued geopolitical conflicts and sustained high diesel prices could further hinder the sector’s recovery. Christopher Rupkey, chief economist at FWDBONDS, warned that escalating energy costs might undermine optimism about a manufacturing resurgence touted by government officials.
