Key Takeaways
- The ISM Manufacturing PMI reached 54.0% in May 2026, the sector’s highest reading since May 2022 and equivalent to 2.2% annualized real GDP growth.
- 16 of 18 manufacturing industries reported growth in May; only Wood Products contracted.
- Only 2% of manufacturing GDP contracted in May, down sharply from 19% in April.
- New Orders hit 56.8% for the fifth consecutive month of expansion; Production reached 54.3% for the seventh straight month of growth.
- Customers’ Inventories held in “too low” territory for the 20th consecutive month, a reliable leading indicator for future production orders.
- 42% of respondent comments cited the Iran conflict, flagging oil price escalation and Strait of Hormuz supply disruption as top concerns.
- Employment contracted for the 32nd consecutive month, though the hiring-to-managing ratio reached a 1-to-1 split in May, the most balanced reading in recent cycles.
The ISM Manufacturing PMI for May 2026 reached 54.0%, the sector’s strongest reading in four years. That result, up 1.3 points from April’s 52.7%, marks the fifth consecutive month of manufacturing expansion. In April, 19% of manufacturing GDP was contracting. In May, that share dropped to just 2%, and 16 of 18 manufacturing industries reported growth.
What the ISM Manufacturing PMI Data Shows
New Orders grew for the fifth consecutive month, rising to 56.8% from 54.1% in April. Production expanded for the seventh straight month, reaching 54.3% from 53.4%. Furthermore, Backlog of Orders grew to 52.2%, its fifth consecutive month of expansion. New Export Orders returned to expansion territory at 50.6%, up 2.7 points from April’s 47.9%. All six of the largest manufacturing industries reported growth in May. These include Computer and Electronic Products, Transportation Equipment, Machinery, Chemical Products, Food and Beverage, and Petroleum and Coal Products.
| Index | May 2026 | April 2026 | Status |
|---|---|---|---|
| Manufacturing PMI | 54.0% | 52.7% | Growing (+1.3), 5th month |
| New Orders | 56.8% | 54.1% | Growing (+2.7), 5th month |
| Production | 54.3% | 53.4% | Growing (+0.9), 7th month |
| Backlog of Orders | 52.2% | 51.4% | Growing (+0.8), 5th month |
| New Export Orders | 50.6% | 47.9% | Growing (returned to expansion) |
| Prices Index | 82.1% | 84.6% | Increasing, 20th month (easing) |
| Employment | 48.6% | 46.4% | Contracting, 32nd consecutive month |
| Customers’ Inventories | 42.7% | 39.1% | Too Low, 20th consecutive month |
One forward-looking indicator stands out. The Customers’ Inventories Index held in “too low” territory for the 20th consecutive month at 42.7%. In practice, that status is consistently associated with accelerating future production orders. Specifically, when customer stock levels are depleted, manufacturers receive replenishment demand in subsequent months, which supports continued expansion into summer 2026.
Geopolitical Risk: Iran Dominates Manufacturer Commentary
Strong headline numbers came alongside persistent operational concern. According to the May 2026 ISM Manufacturing PMI report, 42% of respondent comments cited the Iran conflict directly. In addition, 18% mentioned tariffs and 57% identified pricing volatility as an active issue for their operations. Only 25% of all comments were positive; 69% were negative.
Respondents described direct impacts on their supply chains. One Miscellaneous Manufacturing executive wrote: “The current atmosphere is one of extreme uncertainty and concern for the future in terms of both price stability and longer-term supply continuity related to the Iran conflict and Strait of Hormuz closure.” In contrast, a Chemical Products executive reported unexpected demand increases, adding that stable geopolitics could sustain growth and margins through the back half of the year. As a result, May’s data reflects a manufacturing sector simultaneously navigating strong demand and deeply uncertain cost conditions.
Employment and Prices: The Persistent Challenges
The Employment Index registered 48.6% in May, up 2.2 points from April’s 46.4%, but still in contraction for the 32nd consecutive month. Since January 2023, employment has contracted in 40 of 41 months. However, the hiring picture improved notably. In May, the ratio of manufacturers actively hiring to those managing or reducing headcount reached 1 to 1. That is the most balanced split seen in the recent contraction cycle.
On costs, the Prices Index dropped 2.5 points to 82.1%, marking the 20th consecutive month of raw materials price increases. The easing is real but modest. Specifically, ISM chair Susan Spence cited three cost drivers in May: steel and aluminum value chain pressures, tariffs on imported goods, and petroleum product price increases tied to the Iran conflict. Furthermore, 66.3% of respondents reported paying higher prices in May, down 4 points from April’s 70.3%. That suggests the pace of cost increases is moderating, even as the absolute level remains elevated.
What This Means for Industrial Manufacturers
The ISM Manufacturing PMI’s climb to 54.0% corresponds to approximately 2.2% annualized real GDP growth, according to ISM’s historical regression model. That puts the current expansion on solid footing, supported by broad sector participation. The recovery is not concentrated: 16 of 18 industries are growing, customers are running lean on inventory, and export orders have returned to positive territory.
Consequently, manufacturers who built supply chain flexibility during the recent 10-month contraction period are positioned to capitalize on accelerating demand. Those managing Iran-driven energy cost exposure and semiconductor supply constraints, both flagged directly by respondents in multiple sectors, will need active mitigation strategies through the second half of 2026.
