1. At a Glance

  • ICI measures combined and individual monthly output performance of core/infrastructure industries that feed into the Index of Industrial Production (IIP); it is a key high-frequency lead indicator of industrial and infra activity [1].
  • On 20 July 2026, the Office of Economic Adviser (OEA), DPIIT, Ministry of Commerce & Industry released the first press release of the revised ICI series (Base Year 2022-23), replacing the 2011-12 base series [1].
  • The revision is part of a synchronized base-year overhaul across India's key economic indices in 2026 — GDP, WPI/PPI, IIP, and now ICI — all shifted from base 2011-12 to 2022-23 [2][3].
  • For UPSC: tests both static classification knowledge (core industries, weights, nodal ministry) and current-affairs base-year revision themes common in Prelims/Mains economy sections.

2. Why in the News

  • First press release of the new ICI series issued 20 July 2026, covering data for June 2026 (Provisional Estimates) [1].
  • Comes amid a broader 2026 statistical modernization drive: IIP new series released 1 June 2026 [2]; WPI/PPI new series released [3]; GDP new series with base 2022-23 also released in 2026 [4] — signalling a coordinated shift of India's national accounts/index architecture to a post-COVID, more representative base.

3. Background & Evolution

  • Old series: ICI Base Year 2011-12=100, comprising eight core industries: Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement, Electricity — together carrying 40.27% weight in IIP [5].
  • Revision trigger: Base years are periodically revised to reflect current economic structure; 2022-23 chosen as new base consistent with the parallel revision of GDP, IIP, and WPI base years [2][4].
  • New series released: 20 July 2026, by OEA, DPIIT [1].
  • Back series: Reconstructed from April 2023 onward, hosted on OEA's web portal (eaindustry.nic.in) [1].

4. Core Static Facts

Feature Old Series (2011-12) New Series (2022-23)
Base Year 2011-12=100 2022-23=100 [1]
No. of Core Industries 8 [5] 9 (Iron Ore added) [1]
Nodal Body OEA, DPIIT, Ministry of Commerce & Industry Same [1]
Steel measurement Net production Gross production (aligned with IIP) [1]
Coal measurement Raw coal + coal middling + washed coal Raw coal only (double-counting removed) [1]
Linking Factor 1.47 (for old-new series comparability) [1]
  • New sector weights (2022-23 base): Electricity 30.932%, Refinery Products 22.572%, Steel 17.584%, Coal 5.596%, Iron Ore 4.905%, Cement 4.41%, Natural Gas 3.841%, Fertilizers 2.731% [1].
  • Old sector weights (2011-12 base): Coal 10.33%, Crude Oil 8.98%, Natural Gas 6.88%, Refinery Products 28.04%, Fertilizers 2.63%, Steel 17.92%, Cement 5.37%, Electricity 19.85% [5].
  • June 2026 ICI value: 119.6 (provisional), YoY growth 5.0% [1].

5. Multi-Dimensional Analysis

Economic

  • ICI acts as a proxy lead indicator for IIP (mining, manufacturing, electricity) since core industries hold ~40% IIP weight; early ICI trends foreshadow subsequent IIP releases [5][1].
  • Q1 FY27 (Apr-Jun 2026) core sector growth of 3.6% vs 1.0% in the same quarter previous year signals infra/industrial momentum pickup [1].

Administrative/Governance

  • Reflects inter-ministerial statistical coordination — DPIIT (Commerce Ministry) runs ICI/IIP-adjacent indices while MoSPI runs IIP/GDP; both simultaneously revised base years to 2022-23 in 2026 to keep India's index ecosystem internally consistent [1][2][4].
  • Methodological cleanup (gross vs net steel, single coal category) improves inter-index comparability and reduces double-counting — a governance/data-quality improvement rather than mere rebasing [1].

Scientific/Statistical

  • Introduction of Iron Ore as a 9th core industry reflects growing weight of upstream mining inputs in industrial output, especially steel-linked demand [1].
  • Use of a linking factor (1.47) is the standard NSO/MoSPI-style technique to splice old and new series for continuity of long-run analysis [1].

Historical/Comparative

  • ICI has undergone earlier base revisions too (from base 2004-05 to 2011-12); 2022-23 continues this decadal-ish rebasing cycle, now compressed given the pandemic-driven need for updated weights [1][5].

6. Recent Developments (last 12-18 months)

  • 25 May 2026: Technical Advisory Committee report on IIP base-year revision (2011-12 → 2022-23) released [2].
  • 1 June 2026: MoSPI released new IIP series, base 2022-23, using WPI as deflator [2].
  • 2026: New WPI/PPI series with base year 2022-23 released [3].
  • 2026: New GDP series with base year 2022-23 released [4].
  • 20 July 2026: First press release of new ICI series (base 2022-23) for June 2026 data, by OEA-DPIIT [1].

7. Prelims Hooks

  • ICI new series base year: 2022-23; old base year: 2011-12 [1].
  • Nodal agency for ICI: Office of Economic Adviser (OEA), DPIIT, Ministry of Commerce & Industry (NOT MoSPI) [1].
  • Number of core industries increased from 8 to 9; new entrant: Iron Ore [1].
  • Old 8 core industries: Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement, Electricity [5].
  • Old core industries' combined weight in IIP: 40.27% [5].
  • New series highest-weight sector: Electricity (30.932%); old series highest-weight sector: Refinery Products (28.04%) [1][5].
  • Steel measurement changed from net to gross production in new series [1].
  • Coal category simplified to raw coal only, dropping coal middling and washed coal [1].
  • Linking factor between old and new ICI series: 1.47 [1].
  • Back series (2022-23 base) available from April 2023 onward [1].
  • First press release date of new ICI series: 20 July 2026, covering June 2026 (Provisional Estimates) [1].
  • June 2026 ICI value: 119.6; YoY growth 5.0% (up from 3.2% in May 2026) [1].
  • Iron Ore recorded highest June 2026 growth at +43.9% [1].
  • Q1 FY 2026-27 cumulative core sector growth: 3.6% vs 1.0% in the year-ago quarter [1].
  • MoSPI's parallel new IIP series (base 2022-23) was released on 1 June 2026 [2].

8. Mains Relevance

9. Related Topics to Study Next

  • Index of Industrial Production (IIP) — parent index; core industries feed into IIP with ~40% weight [5].
  • GDP base year revision (2022-23) — parallel national accounts rebasing exercise in 2026 [4].
  • Wholesale Price Index (WPI) / Producer Price Index (PPI) new series — same 2026 rebasing wave [3].
  • DPIIT vs MoSPI mandates — distinguishing which ministry owns which economic index (common trap).
  • National Statistical Commission / NSO — institutional architecture behind India's statistical system.
  • Infrastructure financing (National Infrastructure Pipeline, PM Gati Shakti) — core industries as infra proxy.
  • CPI base year revision — another pending/parallel rebasing exercise worth tracking.

10. Common Errors / Trap Areas

  • Confusing ICI's nodal body (OEA, DPIIT, Commerce Ministry) with MoSPI, which runs IIP and GDP — these are different ministries despite closely linked indices [1][2].
  • Assuming core industries are still eight — the new series has nine, with Iron Ore added [1].
  • Mixing up old vs new series weights (e.g., quoting Electricity's old weight of 19.85% instead of new 30.932%) [1][5].
  • Treating the base year revision as a one-off ICI event — it's part of a coordinated 2026 revision spanning GDP, IIP, WPI/PPI too [2][3][4].
  • Misreading "provisional estimates" for June 2026 as final data — ICI monthly releases are always provisional and subject to revision.
