How do global commodity cycles and climate events like El Niño transmit to domestic food inflation in India? Illustrate with the example of edible oils.

India imported 16.5 million tonnes of edible oil in 2022-23, and domestic output met only 40–45% of its needs [1]. When a country depends this much on imports, world price swings and weather shocks in other countries quickly become food inflation at home. Edible oils show this clearly.

Channels of transmission

• Global commodity cycle: World prices rise when demand is strong, when crops are diverted to biofuel and when stocks run low. For imported goods, these rises reach India through a higher landed cost (import price + freight + duty).
• Climate shocks abroad: El Niño can bring dry weather to Southeast Asia and cut palm output. FAO linked rising palm oil prices to El Niño risks there [2].
• Climate shocks at home: A weak, El Niño-affected monsoon can hurt rainfed kharif oilseeds such as soybean and groundnut. This widens the import gap in the same season.
• Exchange rate: A weaker rupee raises the rupee cost of imports priced in dollars.
• Supply concentration: Palm oil comes from a few Southeast Asian producers, so a local shock there affects India directly.

El Niño / global demand → world palm & soy prices ↑ → landed cost ↑
        → refiners' input cost ↑ → retail oil prices ↑ → CPI food inflation ↑

Flowchart: how an external shock reaches Indian households

Illustration: edible oils, 2026

• The FAO Vegetable Oil Price Index averaged 196.9 points in August 2026. This was its third monthly rise in a row and its highest level since June 2022, driven by palm and soy oil [2].
• With festival demand coming, the Centre cut the Basic Customs Duty on crude edible oils, including palm oil. The duty on crude soybean oil fell from 10% to 5% from 24 September 2026 [2].
• Second-round effect: Cheaper imports push down domestic oilseed prices. Farmers called the cut "an attack on their livelihood" [2]. This weakens the incentive to grow more oilseeds and keeps the dependence in place.

Global cycles and El Niño therefore reach Indian kitchens mainly because of import dependence. Duty cuts can soften the price shock but cannot remove the cause. Lasting protection needs more domestic supply. NMEO-Oilseeds (₹10,103 crore) aims to raise primary oilseed output from 39 MT to 69.7 MT by 2030-31. Together with NMEO–Oil Palm, it aims to meet about 72% of domestic demand [3]. NITI Aayog has called for a dynamic trade policy that balances consumers and growers [1]. A stable, rules-based tariff combined with investment in supply would protect both household budgets and farm incomes, in line with SDG 2 (Zero Hunger).
