National Statistical Office (NSO), Ministry of Statistics and Programme Implementation (MoSPI) recently released the Quick Estimate of Index of Industrial Production (IIP) for the month of July 2026. YoY in July 2026, down from an upgraded 8.8% in June 2026.
Key Highlights
| Sub-Sector | July 2026 Growth Rate | Core Macroeconomic Drivers |
| Overall IIP | 6.7% | Buoyed by structural capital expansions despite localized rural spending sluggishness. |
| Manufacturing | 7.3% | Propelled heavily by domestic engineering, automotive, and consumer electronic production lines. |
| Electricity & Gas | 8.7% | Maintained double-digit momentum but slowed towards month-end due to expanded monsoon rain coverage. |
| Water & Sewerage | 7.4% | Remained highly stable, avoiding the sharp seasonal contraction seen in outdoor activities. |
| Mining | -0.9% | Slid into a brief contraction as heavy rains impacted output against a high base from last year. |
What is Index of Industrial Production (IIP)?
- It is a crucial macroeconomic indicator that measures short-term volume changes in an economy’s industrial production over a given period.
- Essentially, it acts as a monthly pulse check on physical factory, mine, and utility output before quarterly GDP data is published.
- It is compiled and released monthly by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI).
- It is released on 28th of every month (or next working day if 28th is a holiday). The index is compiled with data received from source agencies, which in turn receive the data from the producing factories/ establishments.
- These Quick Estimates will undergo revision in subsequent releases as per the revision policy of IIP.
New IIP Series (Updated 2026)
- In June 2026, MoSPI officially revised the IIP base year from 2011–12 to 2022–23 to better capture modern consumption trends and technical shifts.
- Base Year Value: Set at 100 for the 2022–23 baseline.
- Expanded Product Basket: The updated series now tracks 1,042 specific products mapped into 463 separate item groups (expanded from the old basket of 839 items).
Broad-Sector vs Use-Based Weights
The IIP classifies and assigns mathematical weights to industrial output in two distinct ways:
1. Broad Sector Classification
Under the new series, the broad sector classification includes an expanded mandate to map utility output accurately:
- Manufacturing: Dominates the index with roughly 76.06% of the weight.
- Mining & Quarrying: Holds 11.05% weight.
- Electricity & Gas Supply: Holds 10.87% weight.
- Water Supply, Sewerage & Waste Management: Holds 2.02% weight.
2. Use-Based Classification
This system categorizes goods according to their end-consumer utilization:
- Primary Goods: Basic raw materials and natural inputs.
- Capital Goods: Heavy machinery and plant equipment used directly for domestic asset creation.
- Intermediate Goods: Partially finished components utilized as input for other manufacturing processes.
- Infrastructure/Construction Goods: Materials dedicated specifically to civil construction and building.
- Consumer Durables: Big-ticket retail products like passenger vehicles and large home appliances.
- Consumer Non-Durables: Everyday fast-moving goods like food items, soap, and clothing.
Why does the IIP matter?
- Policy Formulation: The Reserve Bank of India (RBI) utilizes this high-frequency output data to calibrate central interest rates and banking liquidity guidelines.
- GDP Computation: Because actual gross data takes months to process, early advance estimates of quarterly national accounts rely heavily on monthly IIP projections.
- Core Sector Dependency: Nearly 40.27% of the total IIP weight relies directly on India’s Eight Core Industries (such as steel, electricity, crude oil, and coal)
