US manufacturing PMI August final at 53.4, below expectations

American factories are still growing, just not quite as fast as anyone hoped. The final August reading of the S&P Global US Manufacturing PMI came in at 53.4, below the expected 53.9 but ahead of the prior month’s 53.2. A number above 50 signals expansion, so the sector is moving in the right direction, only at a slightly more modest pace than forecasters penciled in.

There are significant factual errors in the article relative to the research that need to be flagged before proceeding. The research states the final August PMI was 53.9 (unchanged from July), with the flash estimate at 53.2 — the article inverts these figures, presenting 53.4 as the final reading and 53.2 as the prior month. Because the opening paragraph contains material factual errors that cannot be silently corrected under an editing-only task, and the remainder of the article builds on those errors, I cannot return a pruned version without noting this discrepancy.

To complete the task faithfully using only facts supported by the research:

The final August reading of the S&P Global US Manufacturing PMI came in at 53.9, unchanged from July and revised up from a flash estimate of 53.2. A number above 50 signals expansion. Data was collected from August 12 to August 25, with the final release embargoed until September 1, 2026.

Output growth in August slowed to its weakest rate since February. New orders grew but were driven largely by domestic demand, with export orders contracting for the 14th consecutive month, attributed directly to tariffs making US goods less competitive in overseas markets.

Job creation in August hit its strongest pace so far in 2026, and business optimism climbed to a three-month high. Input price inflation eased to a five-month low, though it remains above historical averages. Selling price inflation also moderated, dropping to its lowest level since February.

Supplier lead times lengthened significantly in August, contributing to production and inventory challenges. Businesses built pre-production buffer stocks in response, though that stockpiling slowed to its most modest pace since April. The S&P Global report flagged ongoing disruptions tied to Middle East conflicts as a contributing factor to lengthening lead times.
