The US manufacturing sector took a step back in June, with the Institute for Supply Management’s Purchasing Managers’ Index falling to 53.3 from 54.0 in May. That May reading had been the strongest since May 2022, so the retreat is less a crisis and more a natural exhale after a sustained sprint.

Any number above 50 signals expansion, so the sector is still growing. It’s just growing a bit less aggressively than it was a month ago.

The numbers worth paying attention to

The headline PMI decline gets the top billing, but the real story in June’s report is the Prices Index, which fell to 73.0 from 82.1 in May. That is a sharp move down in a single month, and it matters because elevated input costs have been one of the stickier inflation problems facing manufacturers this year.

New Orders held up better than expected, slipping only to 56.0 from 56.8. A reading of 56.0 still points to healthy demand ahead.

Production pulled back more noticeably, dropping to 52.2 from 54.3 in May. Output is still expanding, but the pace of that expansion is easing alongside the broader PMI trend.

Employment remained in contraction territory, though the June reading showed a marginal improvement from the prior month.

Zoom out and the picture is actually fairly constructive. The US economy has now logged 19 consecutive months of expansion under the ISM’s broader measure, which uses a 47.5 threshold rather than 50.

Why this matters for inflation and the Fed

The drop in the Prices Index from 82.1 to 73.0 is significant because it suggests some of the cost pressure that has kept the Federal Reserve cautious about cutting rates may be starting to ease. Survey respondents cited ongoing geopolitical tensions in the Middle East as a factor in pricing, alongside tariff-related costs. The fact that prices fell sharply despite those persistent headwinds is notable.

The production slowdown, from 54.3 to 52.2, is the one component that deserves continued monitoring. If output growth keeps decelerating over the next two or three months while new orders stay elevated, that could indicate capacity or labor constraints rather than softening demand. Employment staying in contraction makes that a plausible concern.

For context, a PMI reading of 53.3 would have looked like a very good month for most of the past two years. The reason it reads as a disappointment is purely relative: May’s 54.0 had raised the bar, and forecasts had penciled in something closer to 54.0 again.
