The ISM manufacturing PMI for October 2026 rose to 55.5 percent, up a full point from 54.5 percent in September, the Institute for Supply Management reported on November 2, 2026. It was the 10th straight month the index sat above 50, the line that separates a growing factory sector from a shrinking one, and the longest such run since 2022.

What the headline number means

The PMI is a diffusion index built from a monthly survey of purchasing managers at US manufacturers. A reading above 50 means more firms reported expansion than contraction; the further above 50, the broader the growth. At 55.5 percent, October was the strongest reading in the current run. ISM also noted that a PMI above 42.5 percent over time generally corresponds to an expanding overall economy, a threshold the index has cleared for 24 consecutive months.

Twelve manufacturing industries reported growth in October and three reported contraction, according to the ISM report distributed through the American Bankers Association's banking journal, a breadth that matches a reading comfortably above 50. Breadth matters because the PMI counts the direction of change, not its size: a sector can report growth whether it expanded a little or a lot. When twelve of fifteen industries are moving the same way, the signal is more reliable than the headline number alone.

The run of expansion is the context that gives October its weight. Ten straight months above 50 is the longest such stretch since 2022, and it follows a long patch in which the index sat below the line and manufacturing was shrinking. A single strong month is noise; a 10-month trend is the sector turning.

Under the hood: production up, prices cooling

The sub-indexes told a cleaner story than the headline alone. Production jumped to 59.0 percent from 56.7, its highest level since November 2021. New Orders edged up to 55.5 from 55.3, and Inventories rose to 51.4 from 48.6, back above the expansion line. The Prices Index, which tracks what manufacturers pay for inputs, eased to 75.2 percent from 77.9, though anything that far above 50 still signals rising costs across energy, metals and electronic components.

The soft spot was hiring. The Employment Index slipped to 52.4 percent from 52.7, below what forecasters had penciled in, suggesting factories are adding to output faster than to payrolls. Supplier deliveries edged up to 59.1 percent, meaning lead times are still lengthening, which in a growing economy is usually a sign of demand running ahead of capacity rather than a problem.

The easing prices index is the line that will draw the most attention from policymakers. At 75.2 percent it still shows input costs rising, and the report noted cost pressure across energy, metals and electronic components, the same component squeeze pushing up prices elsewhere. But the move down from 77.9 points in the direction central bankers want: growth that is not accompanied by an accelerating cost spiral.

One caveat, and a competing survey

Not every gauge agreed. A separate S&P Global US manufacturing PMI fell to 54.9 from 55.9 and missed its forecast, a divergence neither survey explained. Both remain well above 50, so neither points to a downturn, but the gap is a reminder that a single month from a single survey is a data point, not a trend.

Some analysts also noted that part of October's gain reflected stock-building, the rise in inventories from 48.6 to 51.4, which can fade if new orders do not keep pace. In plain terms, factories may be producing partly to refill shelves rather than only to meet a surge of fresh demand, and a November reading back below 54.5 would suggest the October jump borrowed from the months ahead. New Orders rose only marginally, to 55.5 from 55.3, so the production surge is running a little ahead of the demand feeding it, the detail worth keeping an eye on next month.

Why a factory survey matters for your money

Manufacturing is a small slice of US output, but the PMI is one of the first hard reads on the economy each month, published on the first business day before the government's own data. It feeds into how investors and the Federal Reserve read the strength of growth, which in turn shapes the path of interest rates. For the longer view on how the Fed weighs data like this, see how the Federal Reserve works, and for the broader output picture, our coverage of the third-quarter 2026 GDP advance estimate.

A firmer manufacturing sector with cooling input prices is the combination policymakers prefer: growth without a fresh inflation impulse. The prices index easing from 77.9 to 75.2 is the line in this report that monetary-policy watchers will note, even as it stays high.

Manufacturing is only about a tenth of US economic output, far smaller than services, so one month of a factory survey does not decide the path of the economy. Its value is timeliness and cyclicality: factories feel swings in demand early, and the ISM report lands on the first business day of the month, ahead of most official data. That makes it a useful early read rather than a verdict, and it is best weighed alongside the jobs figures, inflation prints and the services PMI that follow.

What to watch

The numbers to track are the November PMI against October's 55.5, whether the Employment Index climbs back toward its recent highs, and whether the Prices Index keeps easing. A reading that holds above 54.5 would confirm the expansion; a drop below it would suggest October borrowed from the months ahead. Every figure here is drawn from the ISM report and is a snapshot of October, not a forecast of what comes next.
