Prior 52.7.US manufacturing growth accelerated in October, with the Institute for Supply Management’s headline index rising to 55.5 from 54.5, beating expectations for an unchanged reading. The sector expanded (above 50.0) for the 10th consecutive month, with production reaching its highest level since November 2021.The details show stronger production and a return to inventory growth, while new orders improved only modestly. Prices paid eased more than expected but remained elevated. Employment continued to expand, although at a slightly slower pace.October components compared with September:New orders: 55.5 vs 55.3 last month.Production: 59.0 vs 56.7 last month.Employment: 52.4 vs 52.7 last month.Supplier deliveries: 59.1 vs 59.0 last month — indicating slower deliveries.Inventories: 51.4 vs 48.6 last month — returning to growth.Customers’ inventories: 41.6 vs 41.6 last month — remaining too low.Prices paid: 75.2 vs 77.9 last month.Backlog of orders: 54.6 vs 56.4 last month.New export orders: 51.2 vs 50.9 last month.Imports: 52.9 vs 51.0 last month.The caution comes from business sentiment, which deteriorated for a third consecutive month despite the stronger headline. ISM said 66% of comments were negative and 34% positive. Among negative comments, pricing volatility appeared in 62%, longer lead times in 41%, tariffs in 25% and the Iran war in 21%, with many respondents citing multiple concerns.Respondents described strong demand tied to data centers, semiconductors, defense and infrastructure, alongside shortages and rising costs. Other manufacturers reported hesitant customers and limited visibility on future purchases. Twelve industries reported growth and three contracted, while five of the six largest manufacturing industries expanded.Quick analysis: The headline is stronger, and the production increase is encouraging. However, new orders barely improved, backlogs grew more slowly and some of the PMI gain came from inventories and slower supplier deliveries. That makes the underlying picture less robust than the headline alone suggests. For the Fed, continued expansion supports patience on rate cuts, while the decline in prices paid offers some relief. The release would normally support the dollar and yields through the growth channel, but softer prices could limit that response.What this report measures: The Institute for Supply Management’s Manufacturing Purchasing Managers’ Index (PMI) is a monthly survey of manufacturing supply executives. Readings above 50 generally signal expansion and readings below 50 contraction; the prices index measures the breadth of input-cost increases, rather than an inflation percentage. Supplier deliveries work differently: a reading above 50 means deliveries are slowing, which can reflect strong demand or supply constraints.
