India will introduce a major upgrade to its inflation and price-tracking framework on June 15, 2026, with the launch of the Producer Price Index (PPI) alongside a revised Wholesale Price Index (WPI) based on the 2022-23 base year.
This marks one of the most significant changes to India’s wholesale inflation measurement system in over a decade.
What is the Producer Price Index (PPI)?
The PPI measures price changes at the producer level before goods and services reach consumers.
Unlike the current WPI framework, India will introduce three separate PPI indicators:
1. Output PPI
Tracks prices received by producers for their products.
Example: The price received by a refinery when selling petrol.
2. Input PPI
Tracks costs paid by producers for inputs and raw materials.
Example: The price a refinery pays to purchase crude oil.
3. Services PPI
Measures price movements in service sectors for the first time in India.
Initial coverage includes:
Banking
Securities transactions
Insurance
Pension fund management
Railways
Air passenger transport
Telecommunications
The services basket is expected to expand gradually.
Why is PPI Important?
The new framework will help policymakers understand:
Cost pressures faced by producers.
How raw material inflation affects finished goods prices.
Supply-chain inflation trends.
Service-sector price movements.
Profit margin pressures across industries.
This makes PPI a more comprehensive indicator than WPI for understanding inflation dynamics.
WPI Will Continue Alongside PPI
The government plans to publish:
WPI
Output PPI
Input PPI
Services PPI
simultaneously for the next five years.
This transition period will allow authorities to evaluate whether PPI offers a better representation of producer-level inflation before considering any complete shift away from WPI.
Major Changes in the New WPI
Expanded Product Basket
The revised WPI will track:
957 items (up from 697 currently)
New Energy Categories Added
The index will now include:
Solar energy
Wind energy
Nuclear power
reflecting India’s evolving energy mix.
Reclassification of Energy Commodities
Crude petroleum and natural gas will move from:
Primary Articles → Fuel & Power
bringing them alongside:
Coal
Electricity
Petroleum products
Revised Weight Structure
Category New Weight (%) Old Weight (%)
Primary Articles 22.76 22.62
Fuel & Power 14.11 13.15
Manufactured Products 63.13 64.23
The changes reflect the growing importance of energy-related sectors in the economy.
Release Schedule
Monthly
WPI
Output PPI
Input PPI
Quarterly
Services PPI
The first release on June 15, 2026 will include:
Provisional May 2026 data
Historical back-series data from April 2023 to April 2026
Why This Matters for Investors
The new framework could provide deeper insights into sectors such as:
Manufacturing
Chemicals
Metals
Oil & Gas
FMCG
Automobiles
Banking
Telecom
Transportation
Investors may gain a better understanding of margin trends by comparing input-cost inflation with output-price inflation.
Conclusion
The introduction of the Producer Price Index represents a significant modernization of India’s inflation measurement framework. By separately tracking producer input costs, output prices, and service-sector inflation, the new system is expected to provide policymakers, businesses, and investors with a more detailed picture of price pressures across the economy while bringing India’s statistical practices closer to international standards.
