American factories ended July on their strongest footing in over four years, according to a closely watched survey released Monday. The Institute for Supply Management (ISM) said its manufacturing index climbed to 55.6 last month, up from 53.3 in June and comfortably above the 50 mark that separates expansion from contraction. Economists had expected a smaller gain, making the jump a pleasant surprise for markets.
The details behind the headline number point to genuine momentum rather than a one-off blip. New orders strengthened, a sign that demand for manufactured goods remains solid, and hiring picked up, suggesting factories are confident enough to add workers. That combination—more orders and more jobs—is the kind of broad-based improvement that tends to lift the wider economy.
But the report wasn't all good news. Input costs stayed elevated, with manufacturers still grappling with supply-chain disruptions linked to ongoing conflicts around the world. Those war-related snarls have kept prices for raw materials and components high, squeezing margins even as output expands.
What the ISM index tells us
The ISM manufacturing index is one of the most-watched gauges of US factory activity. It's based on a monthly survey of purchasing managers at factories across the country, who report whether conditions are improving, worsening, or staying the same across a range of metrics—new orders, production, employment, supplier deliveries, and inventories.
A reading above 50 means the manufacturing sector is expanding, while a reading below 50 signals contraction. The July figure of 55.6 is the highest since early 2020, before the pandemic upended global supply chains and sent the index into a deep slump.
The strength in new orders is particularly notable. It suggests that businesses and consumers are still willing to buy goods, even as interest rates remain elevated and inflation has been slow to cool. Some of that demand may be pulled forward, however, as companies order early to avoid potential shortages or price spikes down the line—a dynamic the ISM report itself hinted at.
Why it matters for investors
For everyday investors, the ISM report is more than just a number. It's a leading indicator of how the broader economy is performing, and it can move markets. A strong manufacturing reading often boosts confidence in corporate earnings, particularly for industrial and materials companies, and can support stock prices.
But the persistent rise in input costs is a double-edged sword. If factories are paying more for materials, they may eventually pass those costs on to customers, keeping inflation higher than the Federal Reserve would like. That could delay interest rate cuts, which investors have been hoping for. The upcoming jobs report will be another key test of whether the economy is cooling enough for the Fed to ease policy.
The US isn't the only country with factories in focus. The picture is mixed globally: China's factory activity slipped into contraction in July, while France's manufacturing sector also contracted. In contrast, Poland's factory slump eased, and Malaysia's factory gauge held at 50.7. The divergence highlights how regional supply chains and energy costs are shaping different outcomes.
What to watch next
Investors will be watching whether the strength in US manufacturing can hold up in the coming months. The ISM report is a snapshot of one month, and it can be volatile. But if new orders and employment continue to climb, it would suggest the industrial sector is a bright spot in an otherwise uneven economy.
On the cost side, any easing of war-related supply disruptions could help bring input prices down, which would be welcome news for both manufacturers and the Fed. Until then, the combination of strong demand and high costs is likely to keep the manufacturing sector—and the broader market—on a cautious but optimistic footing.
