US August Producer Prices Rise 6.6% as Energy, Tariffs and AI Lift Supply Costs

US manufacturing is facing a new wave of supply-chain inflation: the Iran war is driving up energy costs, tariffs imposed by the Trump administration are raising the cost of imported materials, and the AI boom is tightening supplies of key electronic components.

Data from the US Bureau of Labor Statistics show that prices for final producer goods rose 6.6% year on year in August 2026, while the index for intermediate processed goods rose 11.5% year on year, mainly driven by surging diesel prices. Prices for unprocessed goods such as scrap metal rose 12.8% year on year. An August 2026 survey by the Institute for Supply Management showed that more than ten manufacturing industries reported higher raw material prices, with none reporting declines. The ISM manufacturing price index has jumped since the start of 2026, and costs have risen for 23 consecutive months, with petroleum products and steel and aluminum posting notable increases. The index measures changes in raw material purchase prices perceived by US manufacturers, with higher readings indicating greater upstream price pressure.

Based on data from US freight payment and settlement services provider Cass Information Systems, the average cost per shipment rose 16% year on year in August 2026. Cost per shipment refers to the average logistics freight a company pays for each shipment completed.

Kip Eideberg, senior vice president of government and industry relations at the Association of Equipment Manufacturers, said the primary supply-chain problem has shifted from shortages to costs. Zac Rogers, a professor of supply chain management at Colorado State University, said supply chains are paying more money for less inventory. Julie Robbins, chief executive of Ohio guitar effects manufacturer EarthQuaker Devices, said the company has raised prices twice in 2026 and that it needs to spend more and more money for the same goods.

This inflation is becoming an increasingly heavy political burden for Trump ahead of the November 2026 midterm elections. Trump said last week at the Republican National Convention in Dallas that he is bringing prices down substantially. Price pressures have also intensified a bond market selloff, with the US 10-year Treasury yield this week touching 5% for the first time since 2023, as Wall Street widely bets the Federal Reserve will raise interest rates on Wednesday.

Unlike most industries, the electronics sector still faces supply shortages. Rapid data center expansion has sharply increased demand for specialized components such as memory chips and processors, and suppliers are struggling to keep up. An August 2026 survey by the Global Electronics Association, a global electronics industry organization, showed that nearly two-thirds of electronics manufacturers worldwide reported constrained component supplies or extended lead times. Shawn DuBravac, the association's chief economist, said lead times for some components run to several years, and the only ways to resolve this are a full-scale expansion of the entire supply chain or a slowdown in demand.

Rogers, the Colorado State University supply chain professor, said no company will make large capital expenditures without confidence that the market will look the same a year from now.
