India Core Sector Growth Jan 2026: Infra Drives Recovery

CORE SECTOR STORY: SOLID GROWTH PLUS UPWARD THRUST

When the DIPP announced the core (infrastructure) sector growth for January 2026, it was expected to be muted due to a high base. However, the core sector growth for Jan-26 came in better than expected at 4.03%. There are 2 notable things about the core sector data.

Firstly, you cannot miss out the recovery momentum. There was a brief contraction in core sector growth in October 2025 (-0.06%). Since then, core sector has sustained 3 consecutive months of positive trajectory.

Second, is the upward revision of past data. After November saw 31-bps upward revision, even the December 2025 core sector growth was revised upward by 94-bps to 4.66%. The trend suggests a good chance of January 2026 growth also being revised up.

WHY THE CORE SECTOR MATTERS TO INVESTORS

There are 3 reasons why the core sector really matters to Indian investors.

1. The core sector has a substantial weightage in the IIP. In fact, the 8 core sectors constitute about 40% of the Index of Industrial Production (IIP).
2. Core sector is infrastructure and has a strong multiplier effect. Hence strong core growth reflects robust government capex, which fuels downstream demand.
3. The core sector has a big influence on the Nifty. For example, nearly 20% of the Nifty Top-20 by market cap are direct core sector players. The other stocks substantially depend on the core sector growth for operational stability.

Let us now turn to the specific 8 core sectors and how they performed in Jan-25.

CONSTRUCTION IS BIG STORY; ENERGY LAGS

In January 2026, the performance was a "mixed bag," with 5 out of 8 sectors in the positive. What mattered is that the energy story was under pressure, across the board.

On the one hand, the infrastructure boom has been driving the output of steel and cement higher. At the same time, one must note that the key energy basket components (Coal, Crude, Natural Gas, Refinery, and Electricity) make up 74% of the core basket. On account of the Indo-US trade deal; the shift from Russian oil to US and Venezuelan sources has created short-term supply chain pressures. This is reflected in the contraction in Crude Oil (-5.78%) and Natural Gas (-4.99%).

HOW DOES FY26 (CUMULATIVE) COMPARE WITH PREVIOUS YEARS?

The average core sector growth for first 10 months of FY26 stands at 2.82%. However, if you exclude the COVID-19 year, this is the lowest growth rate since FY19. The comparison below gives a bird’s eye view.

1. Last 10-years Average (Pre-FY26): 4.06%
2. Normalised 10-years Average (Ex-COVID): 5.22%
3. Current FY26 Core Sector Growth 10-months: 2.82%

The drag on the core sector is primarily coming from Refinery Products, which carries the highest weightage (28.04%) and has been stagnant in FY26. Despite gross refining margins (GRMs) being relatively robust, it was more about supply chain issues.

KEY SIGNALS FOR EQUITY MARKET INVESTORS

There are some important directions for equity market investors that are coming from the core sector data. Here are some quick takeaways.

1. Let us first look at the implications for Infrastructure & Construction. The consistent outperformance of steel and cement over the year, indicates overflowing order books in downstream construction. Infrastructure stocks remain a high-conviction play.
2. There is a subtle hint on energy transition. Investors should note the shift in the power sector. While coal remains essential, the investment narrative is moving toward renewables. Portfolio value is tilting towards companies leading the green transition.
3. There is also a silent story in fertilizers. The consistent 7 months of positive growth in domestic production is helping cap the import subsidy bill. The sector may be a relative defensive bet, but vital in budget cycles; and also, a key agri-driver.

Here is the last word on the core sector growth for January 2026 and for FY26 cumulative. While headline core sector growth at 4.03% may appear to be modest, the spate of upward revisions are a positive signal. Also, amid the energy headwinds, the resilience of the construction-linked sectors like cement and steel suggest that the infrastructure engine of the Indian economy is chugging along at a good pace.
