The PMI (Purchasing Managers’ Index) is one of the most important and respected leading indicators used by economists, investors, and traders to gauge the health of an economy. It can predict economic slowdowns or accelerations before they are reflected in GDP, unemployment, or inflation data.

What Is the PMI Business Activity Index?
The PMI in the manufacturing sector is calculated based on data provided by purchasing managers across areas such as production volume, new orders, inventory levels, and employment. As a key indicator of a country’s economic output, PMI serves as a crucial barometer of business activity and one of the first signals for business and investment decisions.
How the PMI Index Is Calculated
The PMI index consists of five key components, each with a fixed percentage weight in the overall 100% value:
- New orders in the manufacturing segment (30%)
- Employment level (20%)
- Production volume (25%)
- Inventory levels (10%)
- Supplier deliveries (15%)
To determine the values of these individual factors, managers participating in the survey are asked a series of simple questions. The responses are limited to ‘yes,’ ‘no change,’ or ‘no.’ These structured responses allow for objective and logical conclusions about the current PMI value.
To calculate the manufacturing PMI index, managers are asked about:
- Production volume intensity
- New export orders
- Commodity prices
- Employment level
- Supplier deliveries
- New import orders
- New customer orders
- Short-term supply volumes
- Backlog of unfulfilled orders
How the Publication of the Manufacturing PMI Affects Currency Rates
A PMI value above 50 indicates growth in the manufacturing sector and is a positive factor for the national currency. A PMI value below 50 suggests a slowdown.
Manufacturing PMI is a survey-based or diffusion index that helps track economic cycle dynamics and serves as a leading indicator. The close correlation between the manufacturing PMI and economic performance allows for forecasting future GDP growth rates.
It is important to interpret the PMI not just based on its immediate values. Its impact lies in accurately identifying long-term economic cycles. For example, when the PMI exceeds 50%, it may indicate the peak of business cycles seven months later.
Additionally, a PMI value dropping to 35% is a clear sign of economic stagnation, indicating serious issues in the country’s economy, which will directly affect the national currency. If the PMI remains above 44%, investor reactions may be mixed, as such values often signal the potential for quick recovery, meaning there is no real cause for concern.
