U.S. manufacturing activity expanded at the fastest pace in four years during May, according to the latest data from the Institute for Supply Management. The reading defied ongoing headwinds from supply chain disruptions and rising material costs that have weighed on factories for months.
The ISM's manufacturing index climbed to its strongest level since the spring of 2021, signaling a broad-based pickup in production and new orders. But manufacturers aren't out of the woods yet. They're still dealing with higher prices for raw materials and components, along with longer lead times for deliveries.
Supply chain strains persist
Despite the overall expansion, supply bottlenecks remain a stubborn problem. Several industries reported delays in receiving critical inputs, forcing some to adjust schedules or lean on inventories to meet demand. The May data showed that supplier delivery times stretched again, a sign that disruptions haven't fully cleared.
The ISM notes that transportation and logistics issues, particularly for imported goods, continue to pinch. Some manufacturers said they're struggling to find certain electronics and specialty metals. That's a headache that started during the pandemic and has lingered longer than many expected.
Rising costs squeeze margins
Prices paid for raw materials rose again in May, pushing the index's prices component higher. That means manufacturers are absorbing higher costs or passing them along to customers. Either way, it's a drag — either on profits or on customer relations.
The cost increases are wide-ranging, from steel and aluminum to chemicals and plastic resins. One bright side: energy costs have eased a bit, but that hasn't been enough to offset the broader trend. Analysts watching the data say the combination of strong demand and elevated input costs creates a tricky environment for factory managers trying to plan ahead.
What's ahead for manufacturing
The May ISM report paints a picture of an industry running hot but not without friction. The next month's data will show whether the momentum can hold as summer approaches. A lot depends on whether supply chains loosen up and whether cost pressures start to moderate. If they don't, some of the current growth could slow.
The June ISM release, due early next month, will be closely watched for cracks — or for more signs of resilience.
