The incoming framework introduces three distinct operational metrics: an Output PPI, an Input PPI, and a specialized Service PPI.
The Indian government has initiated a major structural transition by announcing the eventual discontinuation of the Wholesale Price Index (WPI) in favor of a comprehensive Producer Price Index (PPI). To prevent transactional disruptions across commercial contracts that rely heavily on wholesale metrics, the Ministry of Commerce and Industry will run both tracking systems concurrently for a fixed five-year transition period before formally retiring the traditional WPI framework.
The massive policy overhaul aligns India’s domestic inflation metrics with international best practices followed by economic powerhouses like the United States, Germany, and China. Pravin Mahto, Senior Economic Advisor to the Ministry, confirmed that the Department for Promotion of Industry and Internal Trade (DPIIT) will launch the restructured series on June 15, updating the traditional WPI base year from 2011-12 to a modern 2022-23 benchmark.
The incoming framework introduces three distinct operational metrics: an Output PPI, an Input PPI, and a specialized Service PPI. The service vertical will initially evaluate price shifts across seven critical sectors, including banking, insurance, railway transit, and telecommunications. Furthermore, the updated index significantly expands tracking scope, scaling total commodity items from 697 to 957 while integrating nuclear, wind, and solar energy sources into the electricity group.
This structural intervention succeeds a dedicated working group established under NITI Aayog member Ramesh Chand in January 2025. The transition follows intense macroeconomic pressures, highlighted by domestic wholesale inflation scaling a 42-month peak of 8.3 percent recently due to global supply chain disruptions.
Administratively, the economic advisor's office confirmed that while basic WPI and Output PPI datasets will publish on a monthly rotation, the service-centric indicators are slated for a quarterly release schedule moving forward.
