India's Index of Eight Core Industries (ICI) grew 4.8% year-on-year in August 2026, according to provisional government estimates released on 21 September 2026. Cement and electricity led the expansion at 12.5% and 11.6%, while coal, crude oil, natural gas and fertilizers contracted. The July 2026 growth was 5.0%. The cumulative April–August 2026-27 growth was 4.3%, up from 2.4% a year earlier. The ICI is a key lead indicator of industrial output and factory activity for exam purposes.
On 21 September 2026, the government released provisional data showing the Index of Eight Core Industries grew 4.8% year-on-year in August 2026. The reading was slightly lower than July 2026's 5.0% but still reflected steady industrial momentum, led by cement and electricity.
The data covers August 2026 and was published on 21 September 2026 in New Delhi. It uses the updated base year of 2022-23 for the ICI series.
Core-sector indices are used worldwide as early indicators of industrial momentum. India's 4.8% August reading points to moderate expansion; the split between fast-growing construction-linked sectors (cement, electricity) and contracting energy sectors mirrors patterns seen when demand shifts toward infrastructure.

A) Six
B) Seven
C) Eight
D) Ten
Answer: C
Explanation: The index covers eight core industries.
PYQ 2:
Consider the following statements about the Index of Core Industries for August 2026:
The overall index grew 4.8% year-on-year.
Cement recorded growth of 12.5%.
All eight core sectors recorded positive growth.
Which of the above statements is/are correct?
A) 1 and 2 only
B) 2 and 3 only
C) 1 and 3 only
D) All of the above
Answer: A
Explanation: Statements 1 and 2 are correct; several sectors including coal and crude oil contracted, so statement 3 is wrong.
PYQ 3:
Assertion (A): The Index of Core Industries is treated as a lead indicator of the Index of Industrial Production.
Reason (R): The eight core industries form a significant part of the overall industrial output measured by the IIP.
A) Both A and R are true, and R is the correct explanation of A
B) Both A and R are true, but R is not the correct explanation of A
C) A is true, R is false
D) A is false, R is true
Answer: A
Explanation: Because the core sectors form a large share of the IIP, their movement leads and helps explain the IIP's direction.
Question 1 (150 words): Why is the Index of Core Industries considered an important early signal of India's industrial health?
The Index of Eight Core Industries, which grew 4.8% year-on-year in August 2026, is a key lead indicator of India's industrial momentum. It captures foundational sectors — coal, crude oil, natural gas, refinery products, fertilizers, steel, cement and electricity — whose output moves before the broader economy shows change. Because these sectors form a large share of the Index of Industrial Production, the ICI anticipates the IIP's direction. The August split is instructive: cement at 12.5% and electricity at 11.6% signalled strong construction and infrastructure demand, while contractions in coal, crude oil and gas pointed to soft energy output. For policymakers, such granular readings guide decisions on credit, investment and industrial policy. The way forward is to read the ICI alongside inflation and demand data, so that sector-specific weakness is addressed without misreading a single month's number as a durable trend.
Question 2 (250 words): Analyse how movements in the Index of Core Industries can inform India's industrial and infrastructure policy.
The Index of Eight Core Industries is one of India's most closely watched high-frequency indicators, and the August 2026 reading of 4.8% offers a useful case study. The index tracks eight foundational industries whose combined output shapes the broader Index of Industrial Production. Its sectoral detail is what makes it valuable for policy. In August 2026, cement grew 12.5% and electricity 11.6%, both closely tied to construction and infrastructure activity, while coal, crude oil, natural gas and fertilizers contracted. Such a split tells policymakers that growth is being driven by infrastructure demand rather than by energy production, which has direct implications for investment planning.
Historically, the series was modernised with a base year of 2022-23 to reflect the current structure of the economy, improving the accuracy of these signals. The cumulative April–August 2026-27 growth of 4.3%, up from 2.4% a year earlier, suggests a firmer industrial base compared with the previous year.
For industrial and infrastructure policy, these readings help in several ways. Persistent strength in cement and electricity supports the case for continued capital spending and construction-linked schemes. Weakness in coal and hydrocarbons flags the need to secure domestic energy supply and manage imports. Fertilizer contraction can have knock-on effects for agriculture and subsidy planning.
The balanced way forward is to use the ICI as an early-warning tool alongside credit, demand and price data, avoid overreacting to a single month, and target policy support at the specific sectors showing sustained weakness rather than at industry as a whole.
