U.S. Manufacturing Contracts Ninth Straight Month, Tariffs Add Pressure

The U.S. manufacturing sector contracted again in November, according to the Institute for Supply Management survey released December 1, 2025, extending a run of weakness to nine straight months. The report showed broad softening across demand measures, while input price pressures remained a notable headwind, and import tariffs continued to weigh on supply chains and producer margins.

New orders, a leading indicator of future production, fell sharply in November, reflecting softer domestic and export demand. Production and employment components also weakened, underscoring a pullback in factory activity that has persisted through most of the year. The ISM data signaled that manufacturers are confronting a tougher revenue environment even as some input prices have not retreated in line with demand, squeezing margins for many firms.

Analysts point to multiple forces behind the slump. Elevated policy interest rates, aimed at reining in inflation, have cooled investment in capital goods. At the same time, the continuation of tariffs on a range of imported intermediate goods has pushed up costs for manufacturers that rely on global supply chains. Those added costs have been felt unevenly across industries, with firms that import specialized components or steel and aluminum among the most affected. The resulting margin pressure has prompted some companies to slow hiring and delay planned expansions.

The manufacturing slowdown carries implications well beyond factory floors. Manufacturing accounts for roughly one tenth of U.S. economic output and plays an outsized role in business investment and export performance. A prolonged contraction in factories tends to translate into weaker demand for capital equipment and freight services, amplifying the drag on economic growth. Economists warned that the string of negative ISM readings raises downside risks for fourth quarter GDP growth and could slow the recovery in business investment that policymakers have been watching closely.

Policy makers face a tricky balance. Persistent input price pressures, partly tied to tariffs, keep inflation readings stickier than they would be otherwise, even as demand cools. That mix complicates the Federal Reserve's decision making ahead of upcoming meetings. Some economists argue that weaker manufacturing strengthens the case for the Fed to pause further rate increases to avoid tipping the economy into a deeper downturn, while others caution that stubborn price pressures may limit how much easing is warranted.

Markets are watching the print for signals about both growth and inflation. Corporate margins in affected sectors are likely to come under renewed scrutiny, and companies may accelerate efforts to reengineer supply chains or pass costs to consumers where possible. Trade policy therefore remains a near term factor shaping firms decisions on investment and hiring.

The November ISM survey reinforced a pattern of subdued factory activity, where global trade frictions and cost pressures now sit alongside slower demand and higher borrowing costs. How long manufacturers will remain under strain depends in part on whether tariffs are eased, input price trends normalize, and demand picks up enough to absorb higher costs without further margin erosion.
