India’s annual industrial growth fell to 4.3% in fiscal year 2026, dropping from 5.7% in FY25, according to the latest National Statistical Office report. This decline, captured under a new 2022-23 base year, highlights a cooling trend across most manufacturing sectors. Investors may note that this data excludes the large informal economy, potentially understating broader industrial health.
India’s industrial sector is currently navigating a period of cooling momentum, as reflected in the latest Index of Industrial Production (IIP) data released by the National Statistical Office. The data shows annual industrial growth has moderated to 4.3% for the 2025-26 fiscal year, a noticeable decline from the 5.7% recorded in fiscal year 2024-25 and 6.8% in fiscal year 2023-24. Although May 2026 showed a slight month-on-month recovery to 5.1% compared to April's 4.9%, this short-term improvement does not offset the broader slowdown observed over the last several quarters.
New Base Year Reveals Slower Trends
The government recently updated the base year for IIP calculations from 2011-12 to 2022-23. This technical update was intended to better represent the modern Indian economy by including 455 item groups, reflecting structural shifts in production. Interestingly, while this new series provides a more updated basket of goods, it has made the decelerating trend in industrial output more visible than it appeared under the old index. The quarterly average growth rates show a clear downward path, slipping from 5.4% in the September 2025 quarter to 4.3% and 3.9% in the following two quarters of the same fiscal year.
Understanding Data Limitations
For investors, it is important to distinguish between official IIP figures and overall economic activity. The IIP is a primary indicator, but it primarily tracks the formal manufacturing, mining, and electricity sectors. It does not fully capture the vast informal sector, which remains a significant component of India's output. Additionally, the index relies on data collection that can be subject to respondent non-compliance, leading to statistical adjustments.
Another technical factor involves the shift from using the Wholesale Price Index to the Producer Price Index as a deflator for value-based data, which now covers roughly 36% of the basket. Analysis indicates that because both price indices have tracked closely, this change is not the primary reason for the observed cooling in momentum. Instead, the persistent slowdown appears to be driven by underlying demand patterns.
Investors may monitor these quarterly trends to gauge the health of core manufacturing segments. As the industrial sector faces these pressures, future updates will likely focus on whether consumption and private spending can improve to support a rebound in production volume. The performance of key sectors like automobiles, which has remained a notable exception, often serves as a barometer for broader industrial sentiment that participants follow closely.
