U.S. factory activity eased in August as the ISM Manufacturing PMI slipped from a four-year high, but expansion continued. New orders and hiring slowed, while prices paid stayed elevated at 71.1, keeping inflation concerns and Federal Reserve rate-hike risk firmly in focus.
U.S. manufacturing lost some momentum in August, with the ISM PMI easing to 54.6 as new orders and hiring cooled from July’s stronger pace. Even so, the sector remained in expansion, signaling slower but still solid industrial growth rather than a recessionary turn. The bigger market takeaway is that prices paid held at 71.1, keeping inflation pressures elevated and reinforcing the case for a more hawkish Federal Reserve.
U.S. manufacturing cooled in August, but the factory sector did not lose its footing. The ISM Manufacturing PMI fell from July’s four-year high while input prices held at a level that keeps inflation, bond yields, and Federal Reserve policy tightly linked.
Key Takeaways
The ISM Manufacturing PMI fell to 54.6 from 55.6 in July, but manufacturing still expanded for an eighth straight month.
New orders dropped to 53.7 from 56.7, showing that factory demand cooled faster than the headline index.
The employment index slipped to 51.2 from 52.8, leaving factory hiring positive but slower.
Prices paid held at 71.1 for a second month, keeping input inflation elevated and the Fed focused on rate-hike risk.
ISM Manufacturing PMI Cools From a Four-Year High
The August ISM Manufacturing PMI came in at 54.6, compared with 55.6 in July and a 55.2 estimate. July’s reading was the highest since May 2022, so the August decline marks a loss of speed from an unusually strong base.
Still, the direction remains positive. ISM reported manufacturing expansion for the eighth consecutive month and overall economic expansion for the 22nd consecutive month. The index also stayed well above the level associated with contraction. ISM’s historical model linked the August reading with roughly 2.4% annualized real GDP growth.
That combination gives the report its central tension. August was weaker than July, but it was not a factory recession signal. Instead, the data describe solid industrial activity with less momentum. For markets, that is a more subtle message than either a clean growth surge or a hard landing.
New Orders and Factory Hiring Show Slower Manufacturing Momentum
New orders delivered the clearest sign of cooling demand. The index fell to 53.7 from 56.7 in July, against a 56.0 estimate. Even after the decline, new orders expanded for an eighth straight month following four consecutive months of contraction earlier in 2026.
Other details reinforce the softer pipeline. Production reached 58.3, only slightly below July’s 58.5, while backlogs fell to 51.8 from 55.0. Factories were still producing at a strong pace, but fewer unfinished orders were accumulating behind that output.
Employment also lost ground. The index dropped to 51.2 from 52.8 and came against a 52.5 estimate. That reading remained above 50, and ISM said it remained consistent over time with manufacturing employment growth. However, the decline from July’s highest employment reading since August 2022 tempers the outlook for factory hiring.
The pattern is straightforward: production remains strong, demand is expanding at a slower pace, and hiring momentum has cooled. That mix supports continued economic growth while placing more pressure on manufacturers to control costs and protect margins.

Prices Paid at 71.1 Keep Inflation and Fed Hike Risk Alive
The prices-paid index remains the report’s most important policy signal. It held at 71.1 in August, unchanged from July and compared with a 72.0 estimate. Raw material prices have now risen for 23 consecutive months, according to ISM.
ISM linked the pressure to steel and aluminum costs, tariffs on imported goods, and higher petroleum-based product prices tied to the Middle East conflict. Reuters also described supply-chain strains and elevated input costs as central features of the August data. The message is plain in corporate language: pricing volatility and longer lead times are raising the cost of doing business.
That matters because the Federal Reserve’s longer-run inflation goal is 2% PCE inflation. The federal funds rate stood at 3.63% in August, while Reuters-linked market coverage put the probability of a 25-basis-point hike at the September 15-16 meeting around 66% to 70%, up from 39.6% a week earlier.
The continued availability to jobs relative to the number of unemployed, the extremely low layoff rate, the growing shortages and price increase in manufacturing, and the continued expansion in manufacturing activity nonetheless take the Fed another small step toward a rate hike on September 16. - John Ryding, Brean Capital via Reuters
The policy effect is therefore hawkish even though the growth impulse softened. A PMI of 54.6 keeps activity firm, while prices at 71.1 show that inflation pressure has not followed growth lower. That combination reduces the case for near-term easing and helps explain the sharp repricing in rate-hike odds.
Supply Chain Strains, Tariffs, and AI Spending Shape the Outlook
The subindexes show why manufacturers face a mixed operating environment. Supplier deliveries rose to 59.3 from 58.9. ISM classifies a higher deliveries reading as slower deliveries, pointing to continued pressure in the supply chain rather than an easy flow of inputs.
Trade data also shifted. Imports fell to 52.5 from 55.7, while new export orders edged up to 53.2 from 53.0. The export reading stayed positive, but the sharp drop in imports adds to the evidence of changing supply patterns. ISM reported that pricing volatility, increasing lead times, the Iran war, and tariffs dominated manufacturer comments.
Reuters linked some order strength to front-loaded purchases ahead of higher prices and shortages tied to the six-month U.S.-Israeli war with Iran. It also identified the AI spending boom and inventory replenishment as supports for manufacturing activity. Those forces help explain why production stayed at 58.3 even as new orders and backlogs weakened.
For investors, the data favor manufacturers with pricing power, reliable supply networks, and exposure to durable capital spending. The broader sector signal is less forgiving: slower orders paired with prices at 71.1 create a margin test. Companies that pass higher costs through retain leverage, while companies facing weaker demand absorb more of the squeeze.
August ISM Manufacturing Outlook: Expansion With a Cost Problem
The August ISM report captures a late-expansion economy: manufacturing remains firmly positive, but orders and employment have cooled from July’s stronger levels. Prices at 71.1 keep inflation and September rate-hike risk in focus, leaving markets to weigh durable growth against stubborn costs.
▌Common Questions
Frequently asked questions
+What did the August ISM Manufacturing PMI show?
The August ISM Manufacturing PMI fell to 54.6 from 55.6 in July, indicating slower growth in the factory sector. Readings above 50 still signal expansion, so manufacturing remained in positive territory for the eighth straight month.
+Why are investors focused on the ISM prices paid index?
The prices paid index held at 71.1, showing that input inflation remained elevated in August. That keeps pressure on margins, inflation expectations, and Federal Reserve policy.
+Did factory demand weaken in August?
Yes, new orders dropped to 53.7 from 56.7, showing that demand cooled faster than the headline PMI. Even so, new orders still expanded for an eighth consecutive month.
+What does the August manufacturing report mean for the Federal Reserve?
The report is mildly hawkish because growth stayed firm while price pressures remained hot. That combination reduces the case for near-term easing and supports the risk of another rate hike.
