Overview
- The Commerce and Industry Ministry announced Friday that iron ore will be added to the Index of Core Industries, raising the component count from eight to nine.
- The revised ICI uses 2022–23 as its base year and will be published on July 20 with a back‑series starting April 2023 to help link old and new data.
- Method changes include compiling the steel index on gross production instead of net output and keeping only raw coal in the coal category to avoid double counting.
- Weights for the nine sectors are being redistributed on a pro‑rata basis from the IIP 2022–23 weights, a change that will alter how core‑sector results feed into the IIP.
- Recent weak core‑sector readings — 0.5% growth in May and 2.7% for 2025–26 — may be revised in interpretation once the new series replaces the 2011–12 base.
