All-India Wholesale Price Index inflation was 9.78% year-on-year in July 2026, marginally below June 2026's 9.87%; the All Commodities index stood at 110.0 against 110.2 in June.
Among major groups, Fuel and Power inflation was 20.05%, Primary Articles 8.52% and Manufactured Products 8.29% — against 27.41%, 7.0% and 7.48% respectively in June, so the headline eased only because fuel cooled sharply while both other groups rose.
The WPI Food Index, which carries a weight of 24.99%, recorded 6.65% inflation in July 2026 against 6.14% in June.
This is the new WPI series with base year 2022-23, released by the Office of the Economic Adviser, DPIIT on 15 June 2026 in place of the 2011-12 series, alongside a new Output Producer Price Index and a trial Input Producer Price Index.
The final index for May 2026 was revised up from 109.9 to 110.1, taking May inflation from 9.68% to 9.88%; the July provisional estimate was compiled with a weighted response rate of 78.55% against 98.14% for the May final.
The Wholesale Price Index measures prices at the first point of bulk sale, covers only goods, and excludes services entirely — which is why its weights are dominated by Manufactured Products (63.13%) with no rent, education or healthcare in it. The Consumer Price Index measures what a household actually pays at retail, includes services, and is the anchor of India's monetary policy. The Producer Price Index is the newer construct: an Output PPI measures the prices producers receive for what they sell, while an Input PPI measures the prices they pay for what they consume in production. The crucial difference from WPI is that a PPI is built on a resident-producer basis and can cover services, so it avoids the double counting that dogs the WPI, where the same steel is counted once as an input and again inside a finished machine. That is why the Office of the Economic Adviser launched Output PPI and a trial Input PPI alongside the new WPI series rather than simply rebasing WPI.
Simple Analogy: WPI is the price on the wholesale market's board, CPI is the price on your shop bill, and PPI is the price the factory itself records — one for what it sells, one for what it buys.

Compiles and releases the Wholesale Price Index, the Output Producer Price Index and the trial Input Producer Price Index. It revised the WPI base year from 2011-12 to 2022-23 and released the new series on 15 June 2026, expanding the basket from 697 to 957 items and bringing solar, wind and nuclear electricity into the Electricity group.
Compiles the Consumer Price Index and the Index of Industrial Production. Both were rebased in 2026 — CPI to 2024=100 from 12 February 2026 and IIP to 2022-23 from 1 June 2026 — aligning India's principal macro series on recent base years.
The six-member statutory body under Section 45ZB of the Reserve Bank of India Act, 1934 (as amended by the Finance Act, 2016) that sets the policy repo rate to meet the inflation target. It meets at least four times a year. The target — 4% CPI inflation with a tolerance band of ±2% — is notified by the Central Government in consultation with the RBI once every five years under Section 45ZA.
WPI (2022-23, from 15 June 2026), CPI (2024=100, from 12 February 2026) and IIP (2022-23, from 1 June 2026) were all rebased in the same year, deliberately aligning India's macro series so that growth and inflation are read off comparable bases.
Mineral Oils carry a weight of 8.19 in the WPI and drove both the surge and the easing; the same shock shows up in the import bill, the current account deficit and retail fuel pricing.
Flexible inflation targeting was adopted through the Finance Act 2016 amendment to the RBI Act, with CPI as the nominal anchor — the reason a high WPI print and an unchanged repo rate can coexist.
The new PPI framework includes a Service Producer Price Index for seven services — banking, securities transaction, insurance, management of pension funds, railways, air passenger transport and telecom — the first official measure of producer prices for services in India.
The May 2026 index moving from 109.9 to 110.1 on a rise in weighted response rate from 78.55% to 98.14% is a clean illustration of why provisional estimates should be read with caution.

WPI-CPI distinctions and inflation targeting are near-annual in Prelims and standard in banking exams; the 2026 rebasing of all three major indices is new and unusually likely to be asked.

An index of prices producers receive for the goods and services they sell, on a resident-producer basis.
An index of prices producers pay for goods and services consumed in production; currently released on a trial basis for manufacturing.
