A plain-English guide to ISM Manufacturing vs Services.

The Institute for Supply Management publishes two monthly surveys of US economic activity: ISM Manufacturing (first business day of each month) and ISM Services (third business day). Both are diffusion indexes; both are widely watched; both use similar methodology. They measure very different things. This piece is the framework for reading each one, what the specific sub-indexes signal, and how to weight the two against each other in the Fed reaction-function context.

The paired analysis today notes ISM Manufacturing dropped below 50 for the first time since March. This piece is the framework for what that specific event means and how ISM Services on Tuesday could confirm or contradict the signal.

What ISM measures

Both ISM surveys ask purchasing managers at approximately 300-400 companies about business conditions over the past month. Respondents answer a set of yes/better/no/worse/same questions across several categories:

• New orders
• Production (Manufacturing) or Business activity (Services)
• Employment
• Supplier deliveries
• Inventories
• Backlog of orders
• New export orders
• Imports
• Prices (inflation)

Each category produces a diffusion index: the percentage of respondents reporting improvement plus half the percentage reporting no change. Values above 50 indicate expansion; values below 50 indicate contraction.

Manufacturing vs Services: different sectors, different signals

US GDP is approximately 70 percent services, 20 percent manufacturing/construction, and 10 percent other. This suggests ISM Services should carry roughly 3x the weight of ISM Manufacturing in reading the aggregate economy. In practice, market-moving impact is more even: both surveys move markets meaningfully because they capture different parts of the cycle.

• ISM Manufacturing is a leading indicator. Manufacturing tends to turn earlier in the business cycle than services. A manufacturing recession (ISM below 50) can precede a broader recession by 3-9 months. Manufacturing is also more sensitive to global demand, inventory cycles, and commodity prices.
• ISM Services is a coincident indicator. Services reflect current consumer and business demand more directly. When ISM Services drops below 50, the broader economy is typically already in a recession or on the immediate verge of one. Services turns coincident with the cycle rather than leading it.

The specific implication: an ISM Manufacturing print below 50 is a warning signal but not a recession call. An ISM Services print below 50 is closer to a recession signal in real time.

Sub-index breakdown

The headline number gets the attention but the sub-indexes carry the actual signal. Four sub-indexes matter most for market-moving impact:

New orders

The most forward-looking sub-index. New orders lead the headline by 1-2 months. A New Orders reading materially below the headline (5+ points lower) indicates deteriorating momentum. A New Orders reading materially above the headline indicates improving momentum.

Employment

A coincident-to-lagging signal for hiring. When ISM Employment drops materially, the following month's NFP typically shows corresponding softness. Watchers correlate ISM Employment sub-indexes with NFP for the same reference month.

Prices Paid

A leading signal for inflation. ISM Prices Paid measures the rate at which respondents report increasing input costs. Rising Prices Paid typically leads CPI and PCE inflation by 2-3 months on the input-cost channel.

Supplier deliveries

Slow deliveries typically indicate strong demand (supplier constraints). Fast deliveries indicate weakening demand. A dramatic shift in supplier deliveries can flag inflection points in the manufacturing cycle before the headline moves materially.

Reading the July 2026 ISM Manufacturing at 49.2

Headline: 49.2 (below 50, contractionary). This is the first sub-50 reading since March and reverses the modest expansion of April-June.

Sub-indexes (as reported by ISM Monday morning):

• New Orders: 47.8 (below headline; forward momentum is worse than the headline suggests).
• Production: 48.5.
• Employment: 46.2 (materially soft; supports the labor-market softening thesis).
• Prices Paid: 52.4 (above 50 but softer than June's 54.1; inflation pressures easing).

The combination reads: manufacturing sector in a contractionary state, momentum deteriorating, employment weakening, but inflation pressures still present (though easing). This is a modestly stagflationary configuration for the manufacturing sector, which is why the market read the print as broadly dovish (labor softness dominates) but not decisively so (inflation still above 50).

What ISM Services on Tuesday will tell you

The Tuesday August 4 ISM Services release at 10:00 AM ET is the more consequential print for the aggregate economy. Consensus is 52.0 (expansionary). Three possible outcomes:

• In-line print (51-53). Confirms that the services sector is still expanding. The dovish read from the Manufacturing print gets tempered; the overall economy is cooling but not contracting.
• Below-consensus print (below 50). Would confirm broad-based economic weakness. Both sectors below 50 typically signals a recession is either imminent or already underway. This would produce a materially dovish Fed reaction and likely lift gold, weigh on the dollar, and drop yields materially.
• Above-consensus print (54+). Would suggest the manufacturing weakness is sector-specific rather than broad-based. Would push back on the dovish read from Monday and support a more measured Fed reaction-function view.

Reading the pair together

When ISM Manufacturing and ISM Services diverge (one above 50, one below), the market's typical read is that the divergence will persist for 2-4 months and then the two will re-converge. If services holds up while manufacturing weakens, the economy is cooling but not contracting; if services weakens to match manufacturing, the economy is in recession.

The current configuration (Manufacturing 49.2, Services expected 52.0) fits the "cooling but not contracting" pattern. Tuesday's actual print will confirm or reject this reading.

ISM Manufacturing and ISM Services are complementary, not substitutable. Reading both together gives you a much clearer picture of the US economy's current state than either alone. Monday's Manufacturing below 50 is a warning signal; Tuesday's Services print will decide whether it is early-cycle contagion or sector-specific weakness.
