US Manufacturing Production Stalls in May as Supply Chain Pressures Mount

U.S. manufacturing production was unexpectedly flat in May, halting four consecutive months of growth and signaling that persistent supply chain disruptions and rising costs are beginning to weigh on factory activity. The Federal Reserve reported on June 15 that the stall followed an upwardly revised 0.7% advance in April.

The report arrives as businesses navigate volatility stemming from international conflicts that have snarled key shipping routes. Economists suggest that some of the strength in previous months may have been driven by companies placing orders early to build up inventories in anticipation of shortages, a strategy that now appears to be tapering off.

This flatline in manufacturing output should not be mistaken for stability. In our experience, it is often a warning sign of deeper volatility just beneath the surface for small and mid-sized businesses. While large corporations have the resources to absorb sudden freight surcharges or pivot sourcing strategies, smaller firms feel the impact directly on their cash flow and production schedules. This is precisely the environment where proactive operational planning becomes critical. We advise clients that a robust strategy for supply chain optimization is no longer a luxury but a core defensive measure. This involves diversifying suppliers, re-evaluating inventory levels, and stress-testing financial models against further disruptions. Navigating this requires a clear, data-driven approach, and the team at C&S Finance Group LLC at csfinancegroup.com has extensive experience helping businesses build that resilience.

The Federal Reserve's data revealed a significant divergence between different manufacturing sectors. Overall durable goods manufacturing continued to advance, while nondurable goods production declined. The decrease in nondurables was led by pullbacks in petroleum and coal products, plastics and rubber, and textiles. Excluding motor vehicles and parts, manufacturing output was also flat in May, according to the Fed's report.

In contrast, sectors exposed to the ongoing buildout of data centers and artificial intelligence infrastructure showed notable strength. Production of computers and electronic products, electrical equipment, fabricated metals, machinery, and primary metals all increased. The report also highlighted continued strength in the defense sector, with production of defense and space equipment climbing for a sixth straight month to its highest level since December 2019.

The stagnation in factory output aligns with other indicators pointing to worsening supply chain conditions. A separate survey from the New York Federal Reserve released in June showed that delivery times for factories in the state lengthened significantly. The survey's measure of supply availability dropped to a four-year low, indicating that businesses are finding it harder to source necessary inputs.

The same "Empire State Manufacturing Survey" found that its measure of future selling prices jumped to the highest level since 2022, suggesting that firms widely expect to pass on higher costs to customers over the next six months. According to Samuel Tombs, chief U.S. economist at Pantheon Macroeconomics, many businesses had feared supply chain disruptions from the closure of the Strait of Hormuz and consequently front-loaded their orders earlier in the year. This surge in inventory building was always going to be temporary, he suggested, with the May figures reflecting a return to a more cautious posture.

For many U.S. manufacturers, these disruptions have immediate, practical consequences. As noted by industry analysts, major shipping carriers have been forced to reroute vessels, adding significant time and cost to transit schedules. War-risk insurance premiums and freight surcharges have climbed, feeding directly into the cost of raw materials like electronic components and resins.

While manufacturing was flat, total industrial production, which also includes mining and utilities, edged up 0.1% in May. This was supported by a 1.3% increase in mining output, which includes energy extraction, while utilities output fell. On a year-over-year basis, total industrial production in the United States rose 1.7% in May, an acceleration from the 1.4% growth seen in April. Manufacturing production alone was up a more modest 1.4% from May of the previous year. Capacity utilization at factories, a measure of how fully firms are using their resources, was little changed.

Looking ahead, manufacturers and investors will be closely watching for any resolution in the Middle East, as a recently announced agreement to reopen the Strait of Hormuz could ease some logistical pressures, though the timeline for its implementation remains uncertain. The key focus in the coming months will be whether the strength in tech-related manufacturing can continue to offset weakness in other areas and how rising input costs and expected price hikes will impact inflation and consumer spending.
