U.S. Factory Sector Hits 14 Month Low at End of 2025

The U.S. factory sector ended 2025 on a weak note, showing clear signs of stress. Fresh data from the Institute for Supply Management (ISM) shows that manufacturing activity slowed further in December. The slowdown highlights the challenges faced by factories, even though other parts of the U.S. economy are still holding up well.

The ISM Manufacturing Purchasing Managers’ Index, or PMI, fell to 47.9 in December 2025. A PMI number below 50 means factory activity is shrinking. This was the lowest reading in 14 months. More importantly, this marked the 10th straight month where U.S. factories were in contraction. This shows the problem is not short-term but has been building over time.

One of the biggest reasons for this weakness is falling demand. New factory orders continued to decline in December. When orders slow down, factories produce less, delay new projects, and become cautious about future plans. This weak demand is a key reason why manufacturing has struggled for most of the past year.

High costs have also hurt factory operations. Many companies said they are facing higher prices for raw materials and imported parts. Trade tariffs have played a big role in this. Import duties introduced under the Trump administration are now much higher than they were a year ago. These tariffs have increased costs for manufacturers and made it harder for them to protect profit margins.

Because of these rising costs, inflation pressure within the factory sector has stayed high. Even though inflation in the wider economy has eased somewhat, manufacturers are still paying more for inputs. This limits their ability to expand or invest in new capacity.

Jobs in the manufacturing sector have also been affected. Factory employment fell for the 11th month in a row in December. This means many companies are cutting jobs or choosing not to hire new workers. Weak hiring shows that manufacturers are unsure about future demand and are trying to control costs.

Despite the factory slowdown, the overall U.S. economy has not slipped into recession. Manufacturing makes up about 10% of the total economy. Other sectors, such as services, technology, and consumer spending, have continued to perform better. This has helped keep economic growth steady, even as factories struggle.

Still, the latest data disappointed economists. Many had expected factory activity to improve slightly in December. Instead, the PMI fell more than expected. This has raised concerns that the manufacturing slowdown could last longer than previously thought.

Most factory industries reported weak conditions in December. Only a few areas, such as electrical equipment and computer products, showed small signs of growth. However, these pockets of strength were not enough to lift the overall sector.

Looking ahead, policy decisions could influence the future of U.S. manufacturing. The U.S. Supreme Court is expected to rule in early 2026 on the legality of several tariffs. If these tariffs are changed or removed, costs for manufacturers could come down. This may help improve factory activity over time.

However, experts warn that deeper issues remain. Worker shortages, slow investment, and changing global supply chains could delay a strong recovery. Even with policy support, factories may take time to return to steady growth.

In the short term, U.S. manufacturing is likely to stay under pressure. Weak demand, high costs, and trade uncertainty continue to weigh on the sector. In the long term, the broader economy may still grow if non-manufacturing sectors stay strong. But if factory weakness continues for too long, it could start to affect jobs and regional economies that depend on manufacturing.

Overall, the latest data shows that U.S. factories ended 2025 in a difficult position. While the economy remains stable for now, the long-lasting slowdown in manufacturing is a warning sign that policymakers and businesses will closely watch in 2026.
