What is Purchasing Managers' Index?


Purchasing Managers' Index (PMI) is a significant economic indicator used to gauge the health and performance of a country's manufacturing sector. For businesses involved in manufacturing, as well as investors seeking insights into market sentiment, understanding the PMI is of paramount importance. This blog delves into the essence of PMI and why it's a valuable barometer for making informed decisions in the manufacturing space.

Defining PMI

The Purchasing Managers' Index (PMI) serves as an economic compass for evaluating the state of a country's manufacturing sector. It encompasses both the manufacturing sector PMI and services sector PMI. Market research firms, such as IHS Markit, are entrusted with the responsibility of calculating and disseminating PMI data. In India, for instance, IHS Markit regularly computes the PMI, allowing businesses, investors, and policy-makers to glean insights into the sector's performance.

The Calculations Behind PMI

To compute PMI, a structured survey is circulated to the top 500 manufacturing firms in India. These firms' Purchasing Managers fill out the survey, which contains questions focused on various key business metrics and numbers. The variables evaluated in the survey hold varying weightages in the PMI calculation. They include:

1. New Orders (30%)

2. Output (25%)

3. Employment (20%)

4. Suppliers’ Delivery Time (15%)

5. Stock of Items Purchased (10%)

IHS Markit aggregates the responses from the surveyed firms and employs this data to calculate the monthly PMI. The resulting PMI figure plays a pivotal role in understanding the state of the manufacturing sector in India.

Interpreting PMI Figures:

PMI values are interpreted as follows:

1. When the PMI is below 50, it suggests that the manufacturing sector is contracting in the country.

2. A PMI exceeding 50 signifies that the manufacturing sector is expanding.

The Significance of PMI

PMI, along with other business indices and metrics, is an invaluable tool for comprehending industry performance and foreseeing future trends. The strategic use of data and business indicators, such as PMI, is paramount in today's business landscape, equipping professionals with the insights needed to stay ahead in a dynamic market.
