The Purchasing Managers’ Index (PMI) is a widely recognized economic indicator that measures the health of the manufacturing and service sectors. It is derived from monthly surveys of private-sector companies and serves as a vital tool for economic analysis and forecasting.
Definition and Methodology
The PMI is calculated based on key indicators including new orders, inventory levels, production, supplier deliveries, and employment. Survey participants are asked to indicate whether conditions have improved, remained the same, or worsened compared to the previous month. The PMI is presented as an index number between 0 and 100, with a reading above 50 indicating expansion and below 50 indicating contraction.
Key Components of PMI
- New Orders: Measures the volume of new orders received.
- Production: Assesses the rate of production changes.
- Employment: Evaluates employment trends within the sector.
- Supplier Deliveries: Tracks the speed of supplier deliveries.
- Inventory Levels: Indicates stock levels of purchased goods.
Historical Context
The PMI was initially introduced by the Institute for Supply Management (ISM) in the United States in 1948. Since then, similar indices have been developed globally, making PMI a significant tool for international economic comparisons.
