WPI inflation rises to 9.92% in August 2026 — Sharp price pressure in fuel and power
India's WPI-based inflation rose to 9.92% in August 2026, up from 9.78% in July (based on the 2022-23 base year). The fuel and power sector recorded the highest inflation at 22.93%, while inflation stood at 7.76% for primary articles and 8.37% for manufactured products. Inflation in the WPI food index also increased to 7.05%, signaling rising price pressures on food items. While WPI measures wholesale prices, CPI measures retail prices; CPI-based inflation serves as the key indicator for the RBI's monetary policy.
According to provisional estimates from the Ministry of Commerce and Industry, Wholesale Price Index (WPI)-based inflation stood at 9.92% in August 2026, compared to 9.78% in July 2026. This indicates an increase in price pressures at the wholesale level. The current WPI series is calculated using 2022-23 as the base year.
Overall WPI index also rises
The all-India WPI index stood at 110.8 in August 2026, up from 110.0 in July. WPI is a key economic indicator measuring price changes of goods at the wholesale level in the economy and is used to understand inflation trends.
Highest price pressure in fuel and power
Among the three major groups, annual inflation for fuel and power stood at 22.93% in August, significantly higher than the 20.05% recorded in July. Meanwhile, inflation for primary articles stood at 7.76%, and for manufactured products, it was 8.37%. This makes it evident that the fuel and power sector was the primary driver of price pressure in August.
Rise in Food Inflation
The WPI Food Index, which carries a weight of 24.99% in the WPI, recorded inflation of 7.05% in August, up from 6.65% in July. The food index comprises food items categorized under primary articles as well as manufactured food products. Groups such as mineral oils, food items, basic metals, and chemicals also contributed to price pressures.
Difference Between WPI and CPI: Important for UPSC
The WPI (Wholesale Price Index) primarily measures changes in the wholesale prices of goods, whereas the CPI (Consumer Price Index) measures changes in the retail prices of goods and services purchased by consumers. In India, the RBI's primary inflation target for monetary policy is based on CPI inflation. Therefore, the distinction between WPI and CPI is a significant conceptual topic for the UPSC examination.
Revised Figures and Data Reliability
The government has also revised the WPI figures for June. The index for June was adjusted to 110.3 from the initial estimate of 110.2; consequently, the inflation rate for June was also revised. Revisions to provisional WPI figures are possible because final figures are compiled after obtaining more comprehensive data regarding prices and responses.
