What is the PMI Index?

WHAT?

 

The Purchasing Managers' Index (PMI) is an economic indicator derived from monthly surveys of private sector companies. It reflects the prevailing direction of economic trends in manufacturing and services sectors.

 

Who publishes PMI in India?

 

  • Compiled by: S&P Global (formerly IHS Markit)
  • Published for India by: S&P Global
  • Not released by government bodies like MOSPI or RBI

 

Types of PMI in India

 

PMI Type Sector Covered
Manufacturing PMI Factories, industrial output
Services PMI Banking, IT, hospitality, etc.
Composite PMI Weighted average of Manufacturing & Services PMI

 

How is PMI Calculated?

Based on responses to 5 key components from a survey of purchasing managers:

  1. New orders
  2. Output (production)
  3. Employment
  4. Supplier delivery times
  5. Inventories of purchases

Each component is assigned a weight, and the PMI is calculated as a diffusion index.

 

PMI Value Interpretation

 

PMI Value Economic Signal
> 50 Expansion in economic activity
= 50 No change (neutral)
< 50 Contraction in activity

Higher the value above 50, stronger the expansion.

Example

If India’s Manufacturing PMI rises from 52.0 to 55.5 in a month:

  • It indicates stronger expansion in factory activity
  • May lead to positive investor sentiment
  • Could influence RBI to consider inflation-growth trade-offs

Aspect PMI IIP / GDP
Frequency Monthly IIP (monthly), GDP (quarterly)
Timeliness Very timely (early signal) Often delayed
Based On Survey (perception-based) Actual data (fact-based)
Sector Coverage Manufacturing/Services Entire economy (incl. agri.)

 

Why is PMI Important?

 

  • Leading Indicator: Signals future economic performance before GDP/IIP data
  • Monetary Policy Signal: Central banks use it to gauge inflation/slowdown risks
  • Investor Sentiment: Triggers market reactions in equity and currency markets
