Production across India's foundational industrial sectors demonstrated resilient expansion during July. According to official government data, the country's nine core industries achieved a combined growth rate of 5.4 percent in July, nearly doubling the 3.2 percent pace registered in the corresponding month of the previous year. While this performance reflects a minor sequential moderation from the 6 percent growth recorded in June, the broader trajectory remains firm. For the cumulative April to July 2026 period, core sector output expanded by 4.3 percent, marking a significant acceleration compared to the 1.5 percent growth observed during the same four-month window of the previous fiscal year.
Revised Base Year and Core Index Expansion
The Ministry of Commerce and Industry recently updated the measurement framework for these foundational sectors. Beginning in June, the monthly core sector index transitioned to a new base year of 2022-23, replacing the earlier 2011-12 base period. As part of this revamp, iron ore was formally integrated into the tracking framework, expanding the count of primary core industries from eight to nine. Because these nine sectors collectively account for more than 70 percent of the nation's total industrial and commercial ecosystem, their individual and aggregate output trajectories serve as a direct bellwether for overall economic momentum.
Growth Drivers and Contracting Sub-Sectors
July's output data highlighted divergent performances across individual industries. Growth in coal, petroleum refinery products, cement, electricity, and iron ore provided the primary push to the overall index. Conversely, production volumes contracted in crude oil, natural gas, and fertilizers. Steel manufacturing also experienced a noticeable slowdown, with growth decelerating to 2.9 percent in July compared to a robust 15.7 percent expansion recorded in July 2025. Devendra Pant, Chief Economist at India Ratings and Research, noted that fertilizers, crude oil, and natural gas together hold roughly a 14 percent weight in the core index. He pointed out that while output in these three sectors remained in negative territory, the sequential drop in natural gas production showed signs of easing.
August Outlook and Expected IIP Impact
The combined growth of iron ore, electricity, and steel, which together constitute a massive 53.4 percent weight in the index, softened compared to their June levels. Devendra Pant cautioned that owing to base effects, overall core sector growth could moderate further in August, likely dipping below the 5 percent threshold. Building on these trends, Aditi Nayar, Chief Economist at ICRA, projected that the broader Index of Industrial Production (IIP) for July will also reflect this cooling trend. Following a strong IIP growth figure of 7.3 percent in June, the July IIP expansion is expected to ease to a range of approximately 6 to 6.5 percent.
