• US manufacturing PMI revised down to 54.9 in October from 56.0 flash estimate, signaling slower expansion.
  • The final reading still indicates growth, but at a weaker pace than September's 55.9.
  • The downward revision complicates the inflation outlook as price pressures persist.

Slower Expansion

The US manufacturing sector continued to expand in October, but at a slower pace than initially reported. The final S&P Global (SPGI) manufacturing PMI came in at 54.9, down from the flash estimate of 56.0 and below September's 55.9. The reading remains above the 50 threshold that separates expansion from contraction, indicating that business conditions improved, albeit less robustly than previously thought.

The revision marks a significant shift from the preliminary survey, which had suggested the strongest manufacturing growth since May 2022. Instead, the final data points to a modest slowdown from September's robust pace. The 1.1-point downward revision from the flash estimate is notably larger than the historical average absolute difference of 0.3 points for the manufacturing PMI, underscoring the volatility in the survey data.

Underlying Dynamics

The preliminary report had shown strong growth in production and new orders, though at a decelerating rate. Manufacturing employment rose at its fastest pace since March 2012, and suppliers' delivery times lengthened by the most since July 2022. Manufacturers also raised selling prices at the fastest rate since July 2022, driven by higher energy, freight, and raw-material costs. However, the final report's component breakdown is not yet available, making it difficult to pinpoint the exact drivers of the downward revision.

"The final reading suggests that the manufacturing sector is still expanding, but the momentum may be waning," said a source familiar with the survey. "We need to see the details to understand whether this is a demand-side issue or a supply-side constraint."

Policy Implications

The mixed signals from the manufacturing sector add complexity to the Federal Reserve's policy considerations. On one hand, slower growth could ease concerns about overheating; on the other, the preliminary survey indicated accelerating selling prices and strong hiring, which could keep inflation pressures elevated. Chris Williamson, chief business economist at S&P Global, had previously noted that the flash survey was consistent with approximately 5% annualized GDP growth and warned of further inflation pressure. However, that assessment was based on the preliminary data and does not incorporate the final 54.9 reading.

Global Context

The US data come amid a broader global manufacturing slowdown. The Eurozone manufacturing PMI eased to 52.7 from 52.9, while the UK manufacturing PMI rose to 52.8 from 51.9. In the US, the services sector also showed signs of slowing, with the flash services activity index slipping to 57.9 from 58.8. Survey respondents cited higher steel, aluminum, and copper prices linked to tariffs or shortages, as well as rising oil-based input costs and freight charges.

Market Reaction

Financial markets showed little immediate reaction to the revised PMI, as investors awaited further economic data and clarity on the Fed's policy path. The dollar held steady against major currencies, while Treasury yields were little changed. The next key release is the ISM manufacturing survey, due at 10:00 a.m. EST on November 2, which will provide another independent gauge of the sector's health.

What's Next

The focus now shifts to whether the slowdown in manufacturing is a temporary blip or the start of a more prolonged deceleration. The final services and composite PMI data, scheduled for release on November 4, will offer a broader picture of the US economy. For now, the revised manufacturing PMI suggests that the sector remains a source of strength, but one that is losing some steam.

Correction: An earlier version of this article misstated the historical average absolute difference for the manufacturing PMI. It is 0.3 points, not 0.5 points.
