FOR MAINS : India’s IIP data for April 2026 shows manufacturing growing at 6.2% while mining and quarrying contracted by 5.1%. Analyse the implications of this divergence between India’s manufacturing and mining sectors, the structural constraints holding back India’s mineral extraction industry, and the policy measures needed to ensure that raw material supply does not become a bottleneck to India’s manufacturing ambitions under the PLI framework.
Largest IIP component (~76% weight). Index: 119.3 vs 112.3. 17 of 23 industry groups positive. Leaders: Motor Vehicles, Electrical Equipment, Machinery & Equipment. Slightly slower than 6.3% in April 2025.
New series splits electricity into renewable and non-renewable sources — enhanced granularity. Gas supply tracked separately. Reflects India’s growing clean energy mix under the new classification framework.
Only sector to contract. New series adds fuel minerals, metallic minerals (including rare earth), non-metallic minerals, and minor minerals — providing finer granularity on India’s resource extraction.
Brand new sector in IIP — not tracked in the old 2011–12 series. Reflects India’s expanded infrastructure and AMRUT/Smart Cities-driven water and sanitation investment. Broadens IIP’s economic coverage.
- Index of Industrial Production (IIP) is a composite indicator that measures the short-term changes in industrial production in India, compiled and published monthly by MoSPI (Ministry of Statistics and Programme Implementation)
- Released with a 6-week lag — April data released on June 1st, etc.
- Covers the mining, manufacturing, electricity, and now water supply sectors — capturing the pulse of India’s industrial economy
- Used for: quarterly GDP estimation, monetary policy inputs (RBI MPC), industrial policy review, budget planning, and tracking Make in India/PLI scheme outcomes
- The Eight Core Industries Index (cement, steel, coal, crude oil, natural gas, refinery products, fertilisers, electricity) is the most important leading indicator for IIP — has a combined weight of ~40% in IIP
- Sectoral Classification — Groups by industry type:
• Mining & Quarrying (weight: ~8%)
• Manufacturing (weight: ~76% — dominant)
• Electricity & Gas (weight: ~8%)
• Water, Sewerage & Waste Management (new, ~8%) - Use-Based Classification — Groups by end-use:
• Capital Goods — machinery, equipment; signals future investment
• Consumer Durables — TVs, refrigerators, cars; signals household demand
• Consumer Non-Durables — food, beverages; signals consumption
• Intermediate Goods — inputs for production
• Infrastructure / Construction Goods — cement, steel
• Primary Goods — raw materials and basic inputs

India’s first Index of Industrial Production prepared under the Colonial era — primarily tracking textile, jute, and mining output relevant to the British Indian economy. Very limited coverage.
Successive revisions reflected India’s planned industrial economy under the Five-Year Plans — heavy industries (steel, coal, power) gained prominence in the basket as the Nehru-Mahalanobis model drove industrialisation.
The 1993–94 base year revision was particularly significant — reflecting India’s post-1991 liberalisation structural shift from command economy to market economy. Consumer goods and services gained weight.
Base year shifted to 2004–05. Incorporated IT hardware, telecom equipment, and pharmaceuticals — reflecting the post-liberalisation diversification of India’s industrial base. Used until 2017.
2011–12 base year introduced in 2017 — expanded basket to 839 items, improved use-based classification. Aligned with the GDP base year 2011–12. Remained in use for 9 years until the 2022–23 revision in 2026.
The Technical Advisory Committee for Base Year Revision submitted its report recommending 2022–23 as the new base year, expanded basket to 1,042 products, and added water supply as a new sector.
10th revision — First data release under new series showing April 2026 IIP at 4.9%. Simultaneously revises the base year of IIP to align with the GDP/GVA 2022–23 base year revision — maintaining macro-statistical consistency.
| Indicator | Released By | Frequency | Relationship with IIP |
|---|---|---|---|
| IIP (Index of Industrial Production) | MoSPI | Monthly (6-week lag) | Direct measure; base year now 2022–23; leading input for quarterly GDP estimation |
| GDP / GVA | MoSPI (NSO) | Quarterly + Annual | IIP feeds into GDP’s Industry sector estimate; both now use 2022–23 as base year — aligned |
| Eight Core Industries | DPIIT / MoCI | Monthly | ~40% weight in IIP; released ~2 weeks before IIP as an advance indicator; covers coal, crude oil, NG, refinery, fertiliser, steel, cement, electricity |
| WPI (Wholesale Price Index) | DPIIT / MoCI | Monthly | Measures wholesale inflation; base year also revised to 2022–23 simultaneously — maintains price-output consistency for deflation of industrial value added |
| CPI (Consumer Price Index) | MoSPI + MOSPI | Monthly | Measures retail/consumer inflation; base year 2012. CPI is the RBI’s MPC inflation target measure (4% ±2%). Separate from IIP but both inform monetary policy |
| ASI (Annual Survey of Industries) | MoSPI | Annual | Primary data source for IIP weights revision; factory-level output and employment data from registered manufacturing units |
| PMI Manufacturing | S&P Global (private) | Monthly | Purchasing Managers’ Index — a leading indicator for IIP; above 50 = expansion. Faster than IIP (released same month, not 6-week lag) |
- Structural obsolescence — India’s economy changed dramatically between 2011 and 2026. Manufacturing shifted toward electronics, EVs, pharmaceuticals, and renewable energy; the old basket overrepresented declining sectors (CFLs, printing machinery, kerosene)
- Missing modern products — CCTV cameras, credit cards, human vaccines, spacecraft parts, and medical stents were entirely absent from the 2011–12 basket despite being significant modern industrial outputs
- Misaligned with GDP base — GDP had already been revised to 2022–23 in early 2026; IIP remaining at 2011–12 created inconsistency between price and output measures — problematic for deflation calculations and national accounts
- Weight distortion — sector weights based on 2011–12 GVA underrepresented the surge in auto, pharma, and electronics manufacturing relative to their current economic contribution
- Greater representativeness — 1,042 products (up from 839) capture India’s contemporary industrial structure, including the PLI-driven electronics and pharmaceutical surge
- New sector inclusion — Water Supply, Sewerage & Waste Management reflects India’s AMRUT/Smart Cities investment reality; Renewable energy tracked separately from thermal power
- Rare earth & minor minerals now tracked — critical for India’s EV battery and semiconductor supply chain policy monitoring
- GDP-IIP alignment — both now on 2022–23 base; improves real sector analysis, national accounts consistency, and accuracy of quarterly GDP estimates
- GST data integration — new series uses GST filings alongside ASI data for weights — more comprehensive and current than the old ASI-only approach
- Manufacturing at 6.2% remains robust — the core of India’s industrial engine is healthy, with 17 of 23 industry groups in expansion. Motor vehicles, electrical equipment, and machinery leading confirms PLI-driven diversification is bearing fruit
- New series adds Water Supply sector growing 6.6% — a positive reading on India’s infrastructure investment translation into productive output
- The apparent deceleration from old series’ 7.3% (April 2024) is partly a statistical artefact of base year change — series are not directly comparable; the underlying industrial momentum may be stronger than the headline suggests
- Electricity growing 4.9% — consistent with RBI’s capacity utilisation data showing factories running near full capacity
- Mining contraction of 5.1% is significant — constrains raw material availability for downstream manufacturing and signals potential supply-side bottlenecks in metals and minerals
- 4.9% overall growth is below pre-COVID trend of 6–7% — India needs to sustain 7–8% industrial growth to absorb the 7–10 million new workers entering the labour market annually
- The new series cannot be directly compared to old series growth rates — creating a statistical continuity gap that confounds policy assessment and inter-temporal comparison for at least the next 2–3 years
- Only 1 month of new series data available — impossible to assess trend vs noise; analysts caution against over-interpreting any single data point under a new statistical framework
- Provide back-cast data: MoSPI must release historical IIP data recalculated under the 2022–23 series — ideally going back at least 5 years — to enable meaningful trend analysis, seasonal adjustment, and inter-year comparison without the base-year discontinuity problem that currently hampers policy assessment.
- Accelerate mining sector recovery: The 5.1% mining contraction is a structural warning. India’s Critical Mineral Mission must be backed by faster environmental clearances, technology-driven extraction, and exploration investment — especially for lithium, cobalt, and rare earth elements now tracked in the new IIP series.
- Use new granularity for targeted PLI monitoring: The new IIP’s 463 item groups — including CCTV cameras, medical stents, and spacecraft parts — must be actively used by DPIIT to monitor PLI scheme-specific production targets and identify underperforming segments requiring policy recalibration.
- Align WPI and CPI base years: While IIP and GDP are now on 2022–23, CPI remains on 2012 base. A unified base year across all major macro indicators would improve national accounts consistency and monetary-fiscal policy coordination. CPI base year revision should be the next priority for MoSPI.
- Seasonal adjustment for better signal: The new series should incorporate seasonally adjusted IIP data — planned under the GST-linked chain-based approach — so that monthly fluctuations driven by agricultural seasons, festivals, or weather can be filtered out for cleaner industrial trend analysis by RBI and the MPC.
- Mining-Manufacturing linkage policy: Mining’s decline must be addressed as a supply-chain risk to manufacturing — India cannot sustain 6%+ manufacturing growth if raw material extraction is declining. The National Mineral Policy 2019’s push for increased auctioning of mineral blocks must be accelerated, with district-level targets for mining revenue generation.
“The revision of the IIP base year from 2011–12 to 2022–23 is not merely a statistical housekeeping exercise — it is a reflection of India’s transformed industrial structure, with emerging sectors like renewable energy, rare earth minerals, and medical technology now entering the measurement framework.” Critically examine the significance of the new IIP series, its structural improvements over the old series, and how it will improve the quality of industrial policy-making in India.
