ISM Manufacturing Prices
Published:
A monthly survey gauge showing whether U.S. manufacturers are broadly paying higher or lower input prices.
Full explanation
ISM Manufacturing Prices measures whether U.S. manufacturers are paying higher or lower prices for inputs compared with the previous month. It is a diffusion index based on survey responses from purchasing and supply executives, with readings above 50 generally indicating that prices paid are rising for more firms than they are falling. The index is published in the monthly ISM Manufacturing PMI Report, but it is not one of the five components of the headline Manufacturing PMI. Unlike several headline components, the prices index is not seasonally adjusted in ISM’s presentation.
Why traders watch it
Traders watch it as an early signal of manufacturing input-cost pressure that can influence inflation expectations, Treasury yields, Federal Reserve policy pricing and the U.S. dollar. It is especially important when markets are focused on tariffs, energy costs, supply chains or goods inflation.
Market interpretation
- USD
- A stronger prices reading may support the dollar if it raises rate expectations, but it can also be interpreted negatively if it points to margin pressure or weaker real demand.
- Rates
- Higher-than-expected input-price pressure may lift yields through inflation expectations, while softer readings may reduce inflation-risk pricing.
- Commodities
- The index can be read alongside energy, metals and freight costs to assess whether cost pressure is broadening or fading.
Stronger vs weaker outcomes
A higher-than-expected reading may suggest stronger input-cost pressure for manufacturers, while a lower-than-expected reading may suggest easing cost pressure. The FX and rates impact can depend on whether investors treat the data mainly as an inflation signal or as a margin and demand signal.
A higher reading means more surveyed manufacturers reported paying higher input prices, which may indicate broader cost pressure.
A lower reading means price increases are less widespread, or price declines are more common, which may indicate easing input-cost pressure.
Higher readings generally signal broader manufacturing input-cost pressure; lower readings generally signal easing pressure.
Typical volatility
High. The index shows the breadth of reported price increases, not the size of price changes. It covers manufacturing inputs and may not map directly to consumer inflation, especially when margins, supply chains or sector-specific shocks are changing.
Trading considerations
- Read the prices index alongside new orders and production to distinguish inflation pressure from demand strength or weakness.
- Compare the signal with commodity prices, supplier-delivery conditions and official Producer Price Index data.
- Remember that the index measures breadth of price changes, not the average percentage change in costs.
- Be alert to simultaneous surprises in the headline PMI, employment and new orders components.
