What is ISM Manufacturing PMI?
The ISM Manufacturing PMI (Purchasing Managers’ Index) is a monthly survey of purchasing managers at U.S. factories, compiled by the Institute for Supply Management. It blends new orders, production, employment, supplier deliveries and inventories into a single diffusion index.
Why it moves markets
It is one of the earliest reads on the industrial cycle each month and a reliable leading indicator for the broader economy. Manufacturing is cyclical, so the PMI often signals turning points before GDP.
How to read it
The key line is 50: above 50 means manufacturing is expanding, below 50 means it is contracting. Watch the new-orders sub-index (future demand) and prices-paid (input inflation). A drop below 50 is a classic late-cycle warning.
