India’s Industrial Production Grows 5.1% in May 2026: Detailed Report on IIP Quick Estimates : Dharmakshethra

India’s Index of Industrial Production recorded a year-on-year growth of 5.1 percent in May 2026, reflecting continued momentum in manufacturing, strong expansion in electricity generation and steady performance in water supply, sewerage and waste management. The latest Quick Estimates released by the Ministry of Statistics & Programme Implementation show that the overall IIP stood at 122.7 in May 2026, compared with 116.7 in May 2025.

The May 2026 data is important because it comes under the new IIP series with base year 2022–23. The release also marks a methodological transition in the compilation of industrial production data, with MoSPI adopting the Output Producer Price Index as the deflator in place of the Wholesale Price Index for item groups where production is reported in value terms. This change affects 234 out of 463 item groups in the IIP basket, representing 36.02 percent of the total index weight.

The Main Message from the IIP Data

The overall industrial production picture for May 2026 is positive. The headline growth of 5.1 percent indicates broad industrial expansion, mainly supported by manufacturing and electricity. Manufacturing remains the most important sector in the index because of its large weight. Electricity and gas supply recorded the strongest growth among the four major sectors, while mining and quarrying acted as a drag because of contraction in fuel minerals and non-metallic minerals.

The Quick Estimate of IIP at 122.7 shows that India’s industrial output remained above the corresponding level of the previous year. The data also indicates that industrial activity was supported by both investment-linked and consumption-linked categories. Capital goods grew strongly, consumer durables showed healthy expansion, and intermediate goods made the largest contribution among use-based categories.

Why the New IIP Series Matters

The release is significant not only because of the monthly growth figure, but also because of the shift in methodology. MoSPI had released the new IIP series with base year 2022–23 on 1 June 2026 using the Wholesale Price Index as the deflator. After the Department for Promotion of Industry and Internal Trade released the Output Producer Price Index series with base year 2022–23 on 15 June 2026, MoSPI decided to adopt Output PPI as the deflator for relevant item groups.

This transition matters because a large part of industrial production is reported in value terms. When production is measured in value rather than physical quantity, price changes must be removed to estimate real output. The deflator used for this purpose can influence the final production estimate. Output PPI captures producer-level prices in a more direct and granular way than WPI. For value-based item groups, this can improve the estimation of real industrial output.

MoSPI has also stated that the revised PPI-based IIP series supersedes the earlier WPI-based IIP 2022–23 series released on 1 June 2026. This means analysts, researchers, policymakers and media users should rely on the PPI-based series for future interpretation.

Sector-Wise Performance

India’s industrial production is divided into four major sectors under the current presentation: Mining & Quarrying, Manufacturing, Electricity & Gas Supply, and Water Supply, Sewerage & Waste Management.

1. Manufacturing: The Main Driver of Growth

Manufacturing grew by 5.5 percent in May 2026. Its index stood at 122.6, compared with 116.2 in May 2025. Since manufacturing carries the largest weight in the IIP basket, this sector contributed the most to the overall industrial expansion.

The manufacturing sector accounted for 76.062 percent of the index weight. This means even a moderate rise in manufacturing has a large impact on the total IIP. The May 2026 data shows that 16 out of 23 manufacturing industry groups recorded positive growth over May 2025.

The top three positive contributors within manufacturing were:

Manufacture of motor vehicles, trailers and semi-trailers grew by 14.5 percent. This category was supported by passenger cars, auto components, spares and accessories, and commercial vehicles. The performance indicates strength in the automobile and transport manufacturing chain.

Manufacture of electrical equipment grew by 20.8 percent. This was one of the strongest performing manufacturing categories. The major contributors included electrical apparatus for switching or protecting electrical circuits, switchgear, circuit breakers, switches, control panels, meter panels, small transformers, UPS systems and solid-state drives. This points to strong activity in electrical infrastructure, power equipment and industrial electronics.

Manufacture of basic metals grew by 4.6 percent. The contributing item groups included hot-rolled coils and sheets of mild steel, hot-rolled plates of mild steel, and bars and rods of alloy and stainless steel. Basic metals are closely linked to infrastructure, engineering, construction, transport and capital goods.

Other major manufacturing groups also performed strongly. Fabricated metal products grew by 15.5 percent. Computer, electronic and optical products grew by 11.4 percent. Textiles grew by 12.7 percent. Other transport equipment grew by 14.3 percent. Paper and paper products grew by 10.1 percent. Other manufacturing grew by 10.4 percent.

This broad manufacturing picture suggests that industrial momentum was not confined to one narrow category. Growth was seen in transport equipment, electronics, electrical equipment, metals, textiles and engineering-related areas.

Manufacturing Areas That Contracted

Seven manufacturing groups recorded contraction in May 2026. Printing and reproduction of recorded media declined by 10.3 percent. Wearing apparel declined by 8.8 percent. Coke and refined petroleum products declined by 4.7 percent. Leather and related products declined by 4.1 percent. Wood and products of wood declined by 4.1 percent. Tobacco products declined by 1.6 percent. Chemicals and chemical products declined by 1.3 percent.

These contractions show that the manufacturing sector remained uneven across categories. The overall sector grew because high-weight and high-growth segments such as electrical equipment, automobiles, basic metals and fabricated metals outweighed weakness in some traditional and commodity-linked segments.

2. Electricity & Gas Supply: Strongest Sectoral Growth

Electricity & Gas Supply recorded 9.9 percent growth in May 2026. The index stood at 129.6, compared with 117.9 in May 2025. This was the strongest growth among the four major sectors.

Within this sector, electricity generation was the main driver. Electricity grew by 11.1 percent. Renewable electricity generation grew by 18.0 percent, while non-renewable electricity generation grew by 8.8 percent. This indicates that the electricity segment benefited from both conventional and renewable power generation.

Gas supply, however, declined by 7.1 percent. Despite this contraction, the strength in electricity generation was large enough to lift the combined Electricity & Gas Supply category.

The strong growth in electricity is important because power demand is closely linked to industrial activity, urban consumption, agriculture, services, cooling demand and infrastructure growth. Rising electricity generation often reflects broader economic activity.

3. Water Supply, Sewerage & Waste Management: Steady Expansion

Water Supply, Sewerage & Waste Management grew by 5.5 percent in May 2026. The index stood at 145.1, compared with 137.6 in May 2025.

Within this sector, water supply grew by 4.3 percent, while sewerage and waste management grew by 6.9 percent. The sector’s weight in the total IIP basket is small at 2.020 percent, but its steady growth reflects expansion in essential urban services, municipal systems and environmental infrastructure.

This category is increasingly relevant as cities expand and public infrastructure modernises. Growth in water supply and waste management also reflects the expanding role of civic and environmental services in the industrial economy.

4. Mining & Quarrying: The Weak Point

Mining & Quarrying declined by 1.6 percent in May 2026. Its index stood at 112.9, compared with 114.7 in May 2025.

The weakness came mainly from fuel minerals and non-metallic minerals. Fuel minerals declined by 6.4 percent, while non-metallic minerals declined by 6.1 percent. Metallic minerals, including rare earth minerals, grew strongly by 18.3 percent. However, the rise in metallic minerals was not enough to offset the contraction in the other two mining segments.

Mining has a weight of 11.053 percent in the IIP basket. Its contraction reduced the overall industrial growth figure. Without the drag from mining, the headline IIP growth would have looked stronger.

Use-Based Classification: What the Data Shows

The use-based classification gives a different view of industrial activity by grouping production according to economic use. This helps understand whether growth is coming from investment, infrastructure, intermediate production or consumer demand.

Primary Goods

Primary goods grew by 2.6 percent in May 2026. The index stood at 119.6. Primary goods include raw materials and basic goods used across the economy. Growth in this category was positive but modest compared with other use-based categories.

The slower growth in primary goods is partly consistent with the contraction in mining. Since mining-related items influence primary goods, weakness in fuel minerals and non-metallic minerals likely limited growth in this category.

Capital Goods

Capital goods recorded the strongest use-based growth at 12.9 percent. The index stood at 135.3 in May 2026. This is a key signal because capital goods are linked to investment, machinery, equipment and industrial capacity creation.

Strong capital goods growth usually suggests that businesses are investing in equipment, production systems and expansion. The rise in electrical equipment, machinery, fabricated metals and transport equipment supports this interpretation.

Capital goods growth is particularly important for medium-term economic momentum. It indicates that industrial activity is not only consumption-driven but also investment-linked.

Intermediate Goods

Intermediate goods grew by 5.8 percent, with the index standing at 123.1. This category includes goods used as inputs by other industries. Growth in intermediate goods shows that supply chains remained active and that manufacturing demand for inputs continued to expand.

The PIB release identifies intermediate goods as one of the top positive contributors to overall IIP growth. This is important because intermediate goods have a high weight in the index and reflect the health of industrial linkages.

Infrastructure and Construction Goods

Infrastructure and construction goods grew by 5.9 percent. The index stood at 130.8 in May 2026. This category is closely linked with construction activity, public infrastructure, roads, housing, industrial projects and capital formation.

Growth in basic metals, fabricated metal products, electrical equipment and non-metallic mineral products supports this category. The expansion suggests continued activity in infrastructure and construction-linked industries.

Consumer Durables

Consumer durables grew by 7.2 percent, with the index standing at 120.4. Consumer durables include long-lasting goods such as vehicles, appliances, electronics and household equipment.

This growth reflects healthy demand in segments linked to discretionary consumption. The strong performance of motor vehicles and electrical equipment also supports the rise in consumer durables.

Consumer Non-Durables

Consumer non-durables grew by 3.6 percent. The index stood at 118.4. This category includes frequently consumed goods such as food products, beverages, pharmaceuticals and other regular-use consumer items.

The growth was positive but lower than capital goods and consumer durables. This indicates that investment-linked and durable-goods-linked production grew faster than everyday consumption goods during May 2026.

Reading the Table as an Economic Signal

The table shows a clear pattern. Capital goods led the use-based categories with 12.9 percent growth. Consumer durables followed with 7.2 percent. Infrastructure and construction goods grew by 5.9 percent, and intermediate goods grew by 5.8 percent. Primary goods and consumer non-durables grew at a softer pace.

This pattern suggests that the May 2026 industrial expansion was supported by investment demand, infrastructure activity, durable consumption and supply-chain production. It was not driven only by basic goods or everyday consumption.

The top three use-based contributors to overall IIP growth were intermediate goods, capital goods and primary goods. Intermediate goods contributed strongly because of their weight in the index. Capital goods contributed because of their high growth rate. Primary goods contributed because of their large weight, even though their growth rate was moderate.

The Importance of Manufacturing Composition

The manufacturing table gives a deeper picture of India’s industrial structure. High-growth categories such as electrical equipment, motor vehicles, fabricated metals, textiles, electronics and other transport equipment show strength in sectors connected to modern manufacturing, infrastructure and mobility.

Electrical equipment’s 20.8 percent growth is especially notable. It indicates strong production in power distribution equipment, switching systems, transformers, UPS systems and related apparatus. These products are essential for industrial expansion, urban infrastructure, power systems, data infrastructure and renewable-energy integration.

Motor vehicles’ 14.5 percent growth shows that automobile production remained a strong contributor. The mention of passenger cars, auto components and commercial vehicles indicates strength across both consumer and commercial vehicle segments.

Basic metals grew by 4.6 percent and remained a major contributor due to its high weight. Even moderate growth in metals matters because steel and metal products feed into construction, automobiles, machinery, railways, engineering and infrastructure.

What the Data Means for the Economy

The May 2026 IIP numbers show a healthy industrial production environment. The 5.1 percent headline growth indicates steady expansion, while the internal composition shows that the growth was supported by manufacturing, power generation, capital goods and durable goods.

The strong growth in capital goods is a positive sign for investment activity. It suggests that industries may be expanding or upgrading production capacity. Growth in electrical equipment, machinery and fabricated metals supports this view.

The performance of consumer durables suggests that demand for long-lasting goods remained strong. This can be linked to vehicles, appliances, electrical goods and electronics.

The growth in infrastructure and construction goods points to continued momentum in public works, construction and industrial project activity.

At the same time, the contraction in mining shows that the industrial recovery was not uniform. Fuel minerals and non-metallic minerals weakened, and some manufacturing segments such as apparel, petroleum products, chemicals and printing declined.

Policy and Statistical Significance

The adoption of Output PPI as a deflator is a major statistical reform. For value-based production data, using producer-level price indicators can improve the quality of real output measurement. This aligns India’s industrial statistics more closely with international practices.

The change is also important because IIP is an input in quarterly GDP estimation. Better deflation of value-based industrial output can improve the measurement of real industrial production and eventually support more accurate national accounts.

MoSPI has advised users to treat the PPI-based IIP series as the official series for analytical, research and policy purposes. This makes the May 2026 release a key reference point for future industrial analysis.

Conclusion

India’s industrial production data for May 2026 presents a broadly positive picture. The 5.1 percent year-on-year growth reflects strength in manufacturing and electricity, along with steady gains in water supply, sewerage and waste management. Manufacturing remained the backbone of the industrial expansion, supported by automobiles, electrical equipment, basic metals, fabricated metals, electronics, textiles and transport equipment.

The strongest economic signal comes from capital goods, which grew by 12.9 percent. This suggests investment-linked industrial demand remained strong. Consumer durables also showed healthy growth, pointing to demand in vehicles, appliances and electronics. Intermediate goods and infrastructure goods added further strength, showing that production chains and construction-linked sectors remained active.

The main area of weakness was mining, which contracted because of declines in fuel minerals and non-metallic minerals. Some manufacturing categories also remained under pressure. However, the overall structure of the data shows that the positive sectors outweighed the weak spots.

The release is also important because it adopts Output PPI as the deflator for value-based item groups in the new IIP series. This improves the statistical foundation of industrial production measurement and makes the data more useful for economic analysis, GDP estimation and policy assessment.

In simple terms, the May 2026 IIP data shows an industrial economy moving forward, led by manufacturing strength, power generation, investment goods and durable consumption.
