India Launches Producer Price Index to Phase Out WPI in Five Years
The Indian government has launched a Producer Price Index (PPI) for goods and services, aiming to replace the Wholesale Price Index (WPI) within five years. This shift, backed by IMF recommendations, provides a more accurate reflection of price movements across industries.
The Government of India has officially introduced the Producer Price Index (PPI) for both goods and services, marking a significant shift in how the nation tracks price movements. This strategic initiative is designed to gradually replace the existing Wholesale Price Index (WPI) over the next five years, aligning the country’s economic reporting with practices utilized by advanced global economies and recommendations from the International Monetary Fund (IMF).
Transitioning to a Modern Producer Price Index
The decision follows a comprehensive report submitted in April by a working group led by former NITI Aayog member Ramesh Chand. By adopting the Producer Price Index, authorities intend to provide a more accurate reflection of price fluctuations within the economy. Currently, the legacy WPI framework relies on a weightage of 63.12 percent for manufactured goods, 14.11 percent for fuel and power, and 22.76 percent for primary commodities.
The introduction of both input and output PPI metrics is expected to offer a clearer understanding of how price changes at the production level cascade through to finished output. The Commerce and Industry Ministry highlighted that this transition clarifies how inflation experienced by producers on raw materials is ultimately passed on to the final goods produced in the market.
Data Insights and Implementation
As of May 2026, the all-India output PPI for all commodities reached 109.6, showing an increase from 108.6 in April 2026. Simultaneously, an experimental trial Input PPI for the manufacturing sector was recorded at 104.9. The ministry noted that this trial data is crucial for assessing data quality and gathering necessary feedback from industry stakeholders and end-users before a full-scale integration.
The structural composition of the new output PPI for goods is heavily weighted toward manufactured items, which account for 69.93 percent. This is followed by agriculture, forestry, and fishing at 22.16 percent, electricity at 4.49 percent, and mining and quarrying at 3.42 percent. Meanwhile, the first phase of the Service PPI covers seven key sectors: banking, securities transactions, insurance, pension fund management, railways, air passenger transport, and telecommunications.
Unlike the goods index, the Service PPI currently operates without assigned weights, as it does not yet encompass the entirety of the service sector. Future phases will incorporate remaining services using data collected from price surveys of sampled establishments, leveraging information obtained through the GSTN. This systematic approach ensures that the Producer Price Index evolves into a robust tool for monitoring India's economic health.
