American factories are still growing — but the pace is slowing. The S&P Global Manufacturing PMI Final for August landed at 53.2, down from 53.9 in July and confirming that the manufacturing rebound that kicked off in January is losing a bit of steam heading into fall.
That’s not a panic number — anything above 50 still means expansion. But with the ISM Manufacturing Index and JOLTS job openings data both dropping at 10 a.m. Eastern this morning, September 1st is shaping up to be a gut-check day for the factory floor.
The Numbers
Here’s where things stand heading into today’s data deluge:
- S&P Global Manufacturing PMI (August Final): 53.2 — down from 53.9 in July and below the 53.0 flash estimate. New orders expanded at the slowest pace in five months. Source: Trading Economics
- ISM Manufacturing PMI (July): 55.6 — the highest reading since May 2022, powered by a 6.3-point surge in production and employment flipping back into expansion territory. Source: ISM
- ISM Manufacturing Consensus (August): 55.2 — analysts expect a modest pullback from July’s peak, reflecting the cooling signals in the S&P survey. Source: Investing.com
- JOLTS Job Openings (June): 7.359 million — down from May’s revised 7.537M. The July figure, out today, could show further softening with Polymarket odds split between the 7.1M–7.2M and 7.3M–7.4M bands. Source: BLS, Polymarket
Two Surveys, Two Stories
Here’s the puzzle on every trader’s screen this morning: the S&P Global survey says manufacturing cooled in August, while the ISM survey — which uses a different methodology and weights domestic purchasing managers more heavily — could tell a different story at 10 a.m.
The July ISM print of 55.6 was a blowout. Production jumped to 58.5, employment crossed back above 50 for the first time in months, and new export orders flipped from contraction to growth. If August holds anywhere near that level, the S&P cooling signal might be noise. If the ISM dips below 54, it’s confirmation that something real is shifting.
The gap between S&P Global’s manufacturing survey and ISM’s has widened this year — and the truth is probably somewhere in the messy middle.
Market Reaction
Investors aren’t waiting for the data to make up their minds. Dow futures were down roughly 300 points in pre-market trading, S&P 500 futures slipped 0.5%, and global bond yields pushed higher overnight — a combination that suggests markets are bracing for stickier data and a Fed that stays on hold. The 10-year Treasury yield has been grinding upward, reflecting a world where rate cuts keep getting pushed further into the future.
Yesterday the Dow shed about 0.7% on a flare-up in geopolitical risks and end-of-month repositioning. September is historically the worst month for stocks, and the tape is acting like it remembers.
Jobs: The Other Shoe
Alongside the ISM print, the July JOLTS report lands at 10 a.m. — and it’s the last read on labor market churn before Friday’s August jobs report. June’s 7.359 million openings were the lowest since early 2021. Another down-tick would reinforce the story that employers are pulling back on hiring even as the unemployment rate hovers around 4.1%.
Yesterday’s Econonaut brief covered the shrinking labor force participation rate — now at 61.4%, the lowest non-pandemic level since 1976. Fewer people looking for work plus fewer job openings is a weird combination, and it’s one Jerome Powell will have to grapple with at the September FOMC meeting.
Bottom Line
Manufacturing is still in expansion mode, but the wind is shifting. The S&P PMI’s dip to 53.2 is a yellow flag — not a red one. The ISM release at 10 a.m. will either quiet the nerves or amplify them. Either way, with JOLTS, construction spending, and a parade of Fed speakers on the calendar this week, September is coming in hot. The factory floor isn’t empty. But the coffee’s getting cold.
