Key Highlights of the Revised Index of Core Industries (ICI)
The Office of Economic Adviser (OEA) under the Department for Promotion of Industry and Internal Trade (DPIIT) will publish a revised series of the ICI with a base year 2022‑23 on 20 July 2026 at 5:00 PM. This replaces the older series that used the 2011‑12 base.
Key Developments
- Provisional ICI for June 2026 will be released together with a back‑series covering April 2023 to May 2026 (38 months).
- Weightage for the new ICI is derived from the IIP 2022‑23 series released by the Ministry of Statistics and Programme Implementation (MoSPI).
- Iron Ore is added as a core industry, expanding the count from eight to nine sectors.
- The Steel Index will now use gross production data, aligning it with the IIP methodology.
- In the coal segment, only Raw Coal is retained; coal middlings and washed coal are removed to prevent double counting.
Important Facts
The revised ICI follows a strict methodology: weights of basket items are taken from the IIP, then redistributed on a pro‑rata basis so that the total equals 100 %. This ensures that the index reflects current industrial structure and production patterns.
By adding Iron Ore, the index now captures a sector that contributes significantly to steel output and overall industrial growth.
Exam Relevance
Understanding the ICI is crucial for GS‑3 (Economy) as it serves as a leading indicator of industrial performance, influencing policy decisions on manufacturing, investment, and employment. The shift to a newer base year improves comparability with other macro‑economic indicators like GDP and IIP, which are frequently asked in the exam.
Knowledge of how weights are derived from the IIP helps answer questions on statistical methods and the importance of consistent data series, a common theme in the UPSC syllabus.
Way Forward
Stakeholders, including policymakers, analysts, and industry bodies, should monitor the revised ICI for trends in the newly added Iron Ore sector and the updated steel production figures. Regular analysis will aid in assessing the impact of industrial policies and guide future revisions of the index.
Students preparing for UPSC should note the methodological changes, the expanded sectoral coverage, and the alignment with the IIP, as these aspects often form the basis of analytical questions in the economics paper.
