WPI Base Revision & the Move to PPI
India's wholesale-price architecture has been rebuilt. Since 15 June 2026 the Wholesale Price Index has run on a 2022-23 base with a wider 957-item basket. The August 2026 bulletin, issued on 14 September, put wholesale inflation at 9.92 percent on an index of 110.8, with fuel and power alone up 22.93 percent. Two producer-price gauges now print beside it — an Output PPI and a trial Input PPI — and a quarterly Service PPI completes the family. The Index of Core Industries was rebased to 2022-23 on 20 July, adding iron ore as a ninth core industry. All of it sits inside a broad statistical refresh: a five-year WPI-to-PPI transition, MoSPI's first trial Index of Services Production, and the Labour Bureau's rebasing of the labourers' consumer-price indices.
