India's Office of Economic Adviser will release a revised Index of Core Industries on July 20, 2026, at 5:00 PM [1], [2].
This update is critical because it aligns the index with the broader Index of Industrial Production. By updating the base year and weightings, the government aims to improve the accuracy of national accounts, inflation levels, and industrial performance metrics [3], [4].
The revised series will utilize 2022-23 as the new base year [1], [4]. This shift allows the index to better reflect the current structure of the Indian economy and the evolving nature of its industrial output.
As part of the upgrade, the index will expand to cover nine industries [4]. This expansion includes the addition of iron ore, which was previously not included in the core set [4]. The Department for Promotion of Industry and Internal Trade (DPIIT) oversees the Office of Economic Adviser, which manages these key economic indicators [1].
Updating the weights of these industries ensures that the data accurately represents the relative importance of each sector to the overall economy. The move is intended to provide a more precise snapshot of industrial growth and stability across the nation [3], [4].
“The revised series will utilize 2022-23 as the new base year”
Updating the base year and expanding the sector list allows India to capture structural shifts in its economy that occurred after the previous baseline. By including iron ore and adjusting weights, the government can more accurately track the health of its primary industrial drivers, which in turn informs national monetary and fiscal policy.
