Saumitra Chaudhuri Working Group
"Government Working Group constituted March 2012 to design India's Producer Price Index — recommendations remain unimplemented, with experimental PPI compilation underway since ~2017."
The Saumitra Chaudhuri Working Group was constituted by the Government of India on March 19, 2012 under the chairmanship of Saumitra Chaudhuri, then a member of the Prime Minister's Economic Advisory Council, to design and implement a Producer Price Index (PPI) for India. The Working Group's mandate was to formulate methodology, design the basket, prescribe data collection mechanisms, and recommend a road-map for transition from the existing Wholesale Price Index (WPI) to a PPI — bringing India in line with G20 economies that use PPI as their primary producer-stage inflation gauge. The Working Group submitted its report in 2014, recommending phased PPI roll-out. Experimental PPI compilation began around 2017 by the Office of the Economic Adviser (DPIIT, Ministry of Commerce and Industry) but the PPI has not been officially released as of May 2026. WPI continues as the de facto producer-stage inflation index. PPI release would enable more accurate real-value calculation for IIP and GDP, better deflators for industrial output, and improved monetary-policy signals.
GS3 (statistics, economy, monetary policy). Prelims: constitution year, chair, role of PPI vs WPI. Mains: statistical sovereignty, producer-stage inflation measurement, why PPI matters.

Business Standard's May 29, 2026 editorial on the new IIP base year argued that the most critical pending reform is operationalising the PPI — flagging the Saumitra Chaudhuri Working Group's 2014 recommendations as the unfinished agenda.
