El Niño 2026: How a Weak Monsoon Could Affect India's Economy and Stock Market

India is closely monitoring the progress of the 2026 southwest monsoon as El Niño conditions develop in the Pacific Ocean. While falling crude oil prices may offer relief to inflation and import costs, economists believe the monsoon will play a much larger role in determining the country's economic and market performance this year. 

In this article, we explain what El Niño is, how it could affect India's economy and stock market, and the sectors that may benefit or face pressure. 

What Is El Niño? 

El Niño is a climate phenomenon in which sea surface temperatures across the central and eastern tropical Pacific Ocean become warmer than normal. Since the Pacific Ocean influences global weather patterns, this warming can alter rainfall, temperature, and climate conditions across different regions. 

El Niño typically has an inverse relationship with the Indian monsoon, meaning that as El Niño strengthens, monsoon rainfall in India often weakens. 

According to the US National Oceanic and Atmospheric Administration (NOAA), El Niño conditions have officially developed after sea surface temperatures in the tropical Pacific crossed the 0.5°C threshold used to classify the event. 

Monsoon Deficit Raises Concerns 

The 2026 monsoon has started on a weak note. As of June 26, 2026, cumulative rainfall was 42% below the long-term average (LTA), marking the weakest start to the monsoon in a decade. 

The rainfall shortfall has been reported across most regions of the country: 

The deficit has exceeded the rainfall shortfalls recorded during previous El Niño years such as 2019 and 2023 for the same period, increasing uncertainty around the ongoing kharif cropping season. 

The India Meteorological Department (IMD) has lowered its rainfall forecast to 90% of the long-period average, with a 60% probability of deficient rainfall during the season. 

How Could El Niño Affect the Indian Economy? 

Agriculture continues to play an important role in India's economy despite rising irrigation coverage. Around 46% of the country's workforce depends on agriculture, while the kharif season contributes nearly 50% of India's annual grain production. 

A weak or uneven monsoon can affect the sowing of major kharif crops such as rice, pulses and oilseeds.  

Reduced agricultural output can tighten the supply of food grains, vegetables, and pulses, increasing the likelihood of higher food inflation. Rising food prices can weaken household purchasing power and affect overall consumption. 

Although nearly 55% of India's cultivated land now has assured irrigation, reducing dependence on rainfall compared with previous decades, slower agricultural growth could still moderate overall economic growth. Some analysts estimate India's GDP growth could ease to around 6.5% in FY27 if monsoon conditions remain weak. 

Does El Niño Always Lead to a Weak Monsoon? 

Historical data shows that El Niño does not always result in deficient rainfall over India. Between 1951 and 2022, there were 15 El Niño years, and about 40% of them recorded normal or above-normal rainfall. 

For example, despite a Super El Niño in 1997, India received 94.4% of its normal seasonal rainfall. 

In addition, the IMD has indicated that while El Niño conditions are developing, the weather system is expected to strengthen into a full "Super El Niño" only from November 2026. This suggests its impact on the core southwest monsoon season between June and September may be relatively limited.

Which Sectors Could Be Impacted by El Niño? 

A weak monsoon generally has the greatest impact on sectors that are closely linked to rural demand and agricultural activity, including fertilisers, crop protection, tractors, fast-moving consumer goods (FMCG) and entry-level two-wheelers. 

Demand for fertilisers, crop protection products and tractors is closely linked to monsoon conditions, as lower rainfall can affect agricultural activity and farm incomes. 

The entry-level two-wheeler segment also has significant exposure to rural demand. Around 54% of entry-level two-wheeler demand comes from rural India. For companies such as Hero Hero MotoCorp and TVS Motor Company, rural markets account for more than 60% of their sales, making monsoon performance an important demand driver. 

Within the tractor industry, the impact may vary across companies depending on their revenue mix. Escorts Kubota derives more than 80% of its revenue from tractors and agricultural equipment, making it relatively more exposed to monsoon conditions. In comparison, tractors contribute around 21% of Mahindra & Mahindra’s overall revenue, while the company's diversified automotive business provides additional revenue streams that may help offset any slowdown in tractor demand. 

Overall, sectors with a higher dependence on agriculture and rural consumption are likely to remain more sensitive to monsoon performance than businesses driven primarily by urban or export demand. 

Sectors That May Remain Relatively Resilient 

Not all industries are equally exposed to monsoon conditions. Premium consumption categories, premium automobiles, banking, information technology, export-oriented businesses and other urban-focused sectors generally face limited direct impact from weaker rural demand. 

Healthcare and pharmaceutical companies are also often considered relatively defensive because demand for healthcare products tends to remain stable regardless of weather conditions. 

Conclusion 

The progress monsoon will remain a key factor for India's economy and equity markets. Investors will closely monitor the impact of El Niño on rural demand, agricultural output, and inflation in the coming months.
