S&P U.S. Manufacturing PMI: Latest Reading, Historical Chart & Investor Guide

Indicator Snapshot

What S&P U.S. Manufacturing PMI Measures

S&P Global U.S. Manufacturing PMI measures the month-to-month change in conditions in U.S. manufacturing, from a survey of purchasing managers. The indicator is published by S&P Global on a monthly basis and is one of the primary datasets used by investors and economists to monitor this area of the economy.

A diffusion index of U.S. manufacturing conditions published by S&P Global, scaled so that 50 means no change from the prior month, above 50 expansion and below 50 contraction. It is a composite of five survey based sub-indexes.

Why Investors Watch S&P U.S. Manufacturing PMI

It is one of the first monthly reads on factory conditions and is used to anticipate industrial production and the ISM manufacturing report. The delivery times and price components also carry information on supply chain pressure and cost pressure.

The indicator's impact on financial markets depends on multiple factors: whether the reading was expected, the current economic regime, central bank policy stance, and investor positioning. A single data point is rarely sufficient to draw firm conclusions.

How S&P U.S. Manufacturing PMI Is Calculated

A panel of purchasing managers reports whether new orders, output, employment, suppliers' delivery times and stocks of purchases rose, fell or were unchanged. Each response set becomes a diffusion index, and the headline weights new orders at 30 percent, output 25, employment 20, delivery times 15 (inverted) and stocks 10, seasonally adjusted.

The official methodology documentation from S&P Global describes the full calculation process including sample design, weighting and revision procedures.

How to Interpret S&P U.S. Manufacturing PMI Changes

When analyzing S&P U.S. Manufacturing PMI data, investors should consider multiple dimensions simultaneously:

• A reading above 50 indicates that more manufacturers saw conditions improve than worsen from the prior month, while a drop below 50 shows broad contraction.
• Check the components: new orders carry the heaviest weight, so a headline resting on slower supplier deliveries or inventory build is a weaker signal than one led by orders.
• Compare with the ISM manufacturing PMI; the two use different panels and can diverge for months, so agreement between them is the stronger signal.

Limitations of S&P U.S. Manufacturing PMI

Like all economic indicators, S&P U.S. Manufacturing PMI has limitations that investors should understand before drawing conclusions:

• Supplier delivery times are inverted in the calculation, so supply bottlenecks can lift the headline even when demand is soft.
• The survey is diffusion based and captures direction, not magnitude, and a flash version precedes the final with a smaller set of responses.
• No single indicator captures the full complexity of economic conditions, so read this series next to the ones linked below.
