QUICK ESTIMATE OF INDEX OF INDUSTRIAL PRODUCTION AND USE-BASED INDEX FOR THE MONTH OF JANUARY 2026

1. At a Glance

Index of Industrial Production (IIP) is the volume indicator that measures short-term changes in industrial output of Mining, Manufacturing, Electricity; base year 2011-12 = 100 [S1][S2].
Released as a Quick Estimate on the 28th of every month (or next working day) by the National Statistical Office (NSO), Ministry of Statistics & Programme Implementation (MoSPI) [S1].
January 2026 IIP grew 4.8% YoY, decelerating from 7.8% in Jan 2025 — relevant for GS-III "Indian Economy & Industry" and Prelims data-based MCQs [S1].

PIB release dated 02 March 2026 (PRID 2234512) — Quick Estimate of IIP for January 2026 placed industrial growth at 4.8%, against 7.8% (QE) in Jan 2025 [S1].
Coincides with MoSPI's ongoing Base Revision exercise for GDP, IIP and CPI; third pre-release consultative workshop held at Chennai on 30 Jan 2026 [S3].

IIP first compiled in India in 1950 with base 1937; revised bases — 1946, 1951, 1956, 1960, 1970, 1980-81, 1993-94, 2004-05, and current 2011-12 [S2].
Compiled under the Collection of Statistics Act, 2008; data flow from 14 source agencies to NSO [S2].
Quick Estimate introduced to reduce reporting lag (T+42 days) and is subsequently revised under the IIP revision policy [S1].

Parent Ministry: Ministry of Statistics & Programme Implementation (MoSPI); compiled by NSO [S1][S2].
Base year: 2011-12 = 100 [S1].
Sectoral weights (2011-12 series): Mining ~14.4%, Manufacturing ~77.6%, Electricity ~8.0% [S2].
Use-based classification (6 categories): Primary, Capital, Intermediate, Infrastructure/Construction, Consumer Durables, Consumer Non-durables [S1].
January 2026 headline indices: IIP = 169.4 vs 161.6 in Jan 2025 [S1].
Sectoral indices Jan 2026: Mining 157.2 (4.3%), Manufacturing 167.2 (4.8%), Electricity 212.1 (5.1%) [S1].
Use-based indices Jan 2026 (growth YoY): Primary 167.9 (3.1%), Capital 124.4 (4.3%), Intermediate 182.8 (6.0%), Infrastructure/Construction 227.7 (13.7%), Consumer Durables (6.3%), Consumer Non-durables (−2.7%) [S1].

Economic
Overall IIP at 4.8% indicates moderation from 7.8% YoY in Jan 2025 — base effect plus softness in consumer non-durables (−2.7%) signal weak rural/mass-consumption demand [S1].
Infrastructure/Construction goods at 13.7% reflects continued capex push (PM Gati Shakti, NIP) [S1].
Sectoral
Electricity (5.1%) leads, aided by demand and capacity additions; Mining (4.3%) stable [S1].
Capital goods (4.3%) moderate — proxy for private investment cycle [S1].
Administrative / Statistical
Quick Estimate is revisable; final figures appear in subsequent releases under the IIP Revision Policy [S1].
Base revision to a more recent year is under consultation (Chennai workshop, Jan 2026) — current base 2011-12 widely seen as outdated [S3].
Policy linkage
IIP feeds into GVA computation (manufacturing), MPC decisions, and the PMI complementarity used by RBI [S2].

02 Mar 2026 — Jan 2026 QE released: IIP +4.8% [S1].
30 Jan 2026 — MoSPI's Third Pre-release Consultative Workshop on Base Revision of GDP, IIP and CPI, Chennai [S3].
Feb 2026 QE (PRID 2246871) also issued, indicating continuing monthly cadence [S4].

IIP base year is 2011-12 [S1].
IIP is released by NSO under MoSPI, not RBI [S1].
IIP has three sectors: Mining, Manufacturing, Electricity (Construction NOT included) [S1].
Use-based classification has six categories [S1].
Quick Estimate released on the 28th of every month (next working day if holiday) [S1].
Manufacturing has the largest weight (~77.6%) in IIP 2011-12 series [S2].
Jan 2026 IIP YoY growth = 4.8% (vs 7.8% in Jan 2025) [S1].
Infrastructure/Construction Goods posted the highest use-based growth at 13.7% in Jan 2026 [S1].
Consumer Non-durables contracted (−2.7%) in Jan 2026 [S1].
Statutory backing for data collection: Collection of Statistics Act, 2008 [S2].
Electricity sector index Jan 2026 = 212.1 (highest among the three sectors) [S1].
Base revision consultations are ongoing for GDP, IIP, CPI simultaneously [S3].

GS-III — Indian Economy: Growth & development; Industrial policy; Macroeconomic indicators.
Syllabus heading: "Issues relating to planning, mobilisation of resources, growth, development … Effects of liberalization on the economy, changes in industrial policy."
Probable stems: 1. "Examine the structural weaknesses revealed by the divergence between infrastructure goods and consumer non-durables in recent IIP releases." 2. "Critically evaluate the need for base-year revision of IIP, GDP and CPI in India." 3. "IIP is a volume index of short-term industrial dynamics — discuss its limitations as a proxy for manufacturing health."

GVA vs GDP methodology — IIP feeds the manufacturing GVA.
CPI & WPI — sister indices from MoSPI/DPIIT; same base-revision exercise [S3].
Eight Core Industries (ICI) — released by DPIIT, ~40% weight inside IIP.
PMI Manufacturing (HSBC/S&P Global) — high-frequency complement.
PLI Schemes — link to manufacturing growth trajectory.
National Statistical Commission (Rangarajan, 2005) — institutional backbone.
PM Gati Shakti & National Infrastructure Pipeline — drives infrastructure goods.
Collection of Statistics Act, 2008 — legal basis for data reporting.

Wrong base year: Current base is 2011-12, NOT 2004-05 or 2012-13.
Wrong sector list: IIP covers Mining, Manufacturing, Electricity — Construction is excluded (it falls under GDP but not IIP).
Wrong ministry: Released by MoSPI/NSO, not RBI or DPIIT (DPIIT releases the Eight Core Industries index).
Use-based ≠ Sector-based: Six use-based categories are a separate cross-classification, not the three sectors.
Quick Estimate is not final — figures are revised in subsequent months under the revision policy.
