Wholesale inflation surges to 9.68% in May 2026 on crude oil spike

Monday, 15 June 2026· 5 min read·Source: Mint

India's Wholesale Price Index (WPI) inflation climbed to a series high of 9.68% in May 2026 under the new 2022-23 base year, up from 8.26% in April, as fuel and crude petroleum prices surged sharply amid the West Asia conflict. The wholesale rate is now running far above retail (CPI) inflation, reflecting cost pressures at the producer/wholesale stage. Officials noted that easing West Asia tensions could cool energy prices and offer some relief in the June print. WPI is compiled by the Office of the Economic Adviser in the Department for Promotion of Industry and Internal Trade (DPIIT).

Background & Context

The Wholesale Price Index (WPI) measures the average change in prices of a fixed basket of goods at the wholesale level — the first point of bulk transaction — and is released monthly by the Office of the Economic Adviser under DPIIT (Ministry of Commerce and Industry). It differs from the Consumer Price Index (CPI), which the RBI uses for monetary policy and which tracks retail prices. WPI has three major groups: primary articles, fuel and power, and manufactured products. The base year was revised to 2022-23 to better reflect the current economy. India is also moving to introduce a Producer Price Index (PPI) to eventually replace WPI.
