PPI
"India's first Producer Price Index, launched June 15, 2026, measuring prices received by domestic producers — set to gradually replace the Wholesale Price Index (WPI)"
The Producer Price Index (PPI) is an inflation measurement index that tracks prices received by domestic producers for their output at the first point of sale — before goods reach the retail level. India launched its first PPI on 15 June 2026, under the Office of the Economic Adviser (OEA), Ministry of Commerce and Industry. The PPI is conceptually superior to the Wholesale Price Index (WPI) because it measures producer prices net of taxes and trade margins, capturing actual price realisation at the farm gate or factory gate. India's PPI covers three components: Output PPI (prices received for goods and services produced), Input PPI (prices paid for intermediate inputs), and Service PPI (prices for service-sector outputs). The PPI will be gradually phased in over five years as it replaces WPI for official inflation measurement. Most advanced economies — the US, UK, EU — use PPI rather than WPI. India had been one of the last major economies to rely primarily on WPI.
The PPI launch is a landmark reform in India's statistical infrastructure, highly relevant for GS3 (inflation measurement, monetary policy, economic statistics). The WPI-vs-PPI distinction is a recurring exam topic: WPI includes import prices and taxes; PPI excludes them, giving a purer reading of domestic production costs. The PPI better aligns with CPI (Consumer Price Index) in the inflation measurement chain. The launch also reflects the government's broader statistical reform agenda following the National Statistical Commission's recommendations.
- 1 India launched its first PPI on June 15, 2026 (under Office of the Economic Adviser, MoCI)
- 2 Measures prices received by producers at first point of sale — excludes taxes and trade margins
- 3 Three components — Output PPI, Input PPI, Service PPI
- 4 Will gradually replace WPI over a five-year phased transition
- 5 Key difference from WPI — PPI excludes import prices and indirect taxes; WPI includes them
- 6 Most advanced economies (US, EU, UK) already use PPI instead of WPI
- 7 Better aligns with CPI in the inflation-measurement chain from producer to consumer
- 8 Recommended by the National Statistical Commission and various economic surveys
If a wheat farmer receives ₹2,200 per quintal from a mandI trader, the PPI captures that farm-gate realisation — whereas WPI records the price at the wholesale market level including mandi charges and levies. The PPI's cleaner signal helps the RBI separate demand-side from supply-side inflation pressures when setting monetary policy.
