The price of climate change does not limited to the environmental repercussions, melting glaciers or future forecasts of warmer weather. Supermarket receipts are already being seen on bills, agricultural commodity markets, corporate balance sheets and on the monetary policy actions of central banks. Whether it's from vegetables sold in France, beef sold in the United States, cocoa sold in West Africa, rice in India, food production is becoming more expensive and more difficult to guarantee its supply due to increasingly unpredictable weather.

The warning has become more pertinent for India. The retail inflation rose to 5.54% for September 2026, crossing the upper tolerance limit of the Reserve Bank of India (RBI). Food inflation jumped to 7.74% from 5.97% in August. The data show an economy under multiple stresses of unpredictable monsoons, high energy prices, and international commodity shortages and price fluctuations, which all have their roots in the high cost of agriculture.

The impact is not just on the household spending. Food inflation lowers disposable income, eats into consumer demand, drives up wage pressures and creates policy uncertainty for interest rates. As essential items start to cost more, families delay their discretionary spending, impacting everything from the automobile industry to consumer electronics, retail and hospitality.

Extreme temperatures, droughts and excessive rainfall are now having a greater impact on food markets, according to the research conducted by Zero Carbon Analytics on weather-related food price shocks from 2022–2026. This phenomenon, which is often referred to as “climateflation,” is a structural issue: food prices are already more sensitive to environmental shocks and stresses than ever before, even before geopolitical shocks and restrictions on trade.

A notable example is Europe. The 2026 was a hot and dry agricultural drought in France, which affected agricultural production and risked the smallest decadal maize harvest. Consumer maize prices were around 16% higher, courgette prices were up 32% and tomato prices were up 31%. Maize is important to humans not only as food, but also as a feed for animals. When the price of maize increases, so does the cost of poultry, dairy products and meat in the future.

The same is true with the cattle industry in the United States. Beef prices increased almost 15 per cent year-on-year, with drought, poor pasture and reduced herd numbers all playing a role. Few years are required to rebuild cattle herds so the impact of a poor crop season can last well after the rains have returned.

The Spanish tomato growers were hit by too much rain in the winter, and too much heat in the summer, resulting in a near 11% year-over-year price increase for tomatoes. Unusually warm water has affected conditions for nori, which is used in sushi, in Japan, making the price of the seaweed about 20% higher by March. The trends highlight the various ways in which the impacts of climate disruption on crops, livestock and marine food production can manifest.

At the same time, the international food industry is facing a new challenge to El Niño. Production of cocoa, coffee and sugar is especially vulnerable due to its emphasis on growing these commodities in climate-vulnerable areas. In recent times, cocoa prices have been running towards $5,867 per tonne, well above their lows in February, but still shy of the extraordinary highs seen in 2024. As the manufacturing companies start to see higher input costs, they can start to raise the retail price, cut down on product size, or change their product formulation.

The Indian internal experience is more alarming since food is a significant portion of household consumption. Onion price inflation has hit about 108% for September, while ginger and garlic have seen more than half price hikes. Rice inflation touched a high of 8.25%, indicating pressure on agricultural output and market supplies. Delayed monsoon and less cultivation in important onion growing regions has affected the onion production.

The cost impact is already there in the daily meals. The price of a home-cooked vegetarian thali rose by around 10% year-on-year in September to ₹30.8 from ₹28.1, CRISIL Intelligence estimated. The saving for a family of two such meals is about ₹162 per month, before they add up other items of their consumption like food, transportation, household needs etc.

It also presents tough options for government as agriculture inflation rises. Although buffer stocks, export bans and import changes can temporarily help reduce pressure, the use of these instruments on a regular basis can cause market distortion and deter private investment. India is estimated to have about 38 million tonnes of rice stocks of government stocks for supply management. However, it is not possible for reserves to make up for a series of production shocks indefinitely.

The Reserve Bank of India has a similar complex challenge in front of it. Earlier in October, its benchmark repo rate was increased to 5.50 percent and the inflation projection was changed to 5.2 percent for FY27. Expensive loans can dampen consumer needs but can't re-create lost crops, restore groundwater or repair broken agricultural supply lines. Monetary tightening may then have the effect of cooling investments, however, without fixing the root cause of food inflation.

Energy markets are an additional vulnerability in the global market. The rising crude oil price leads to more investment in agricultural machines, irrigation, production of fertilisers, refrigeration and transportation. The appreciation of the rupee will also raise the prices of imported edible oils, fertilisers and energy. The impact of the combined pressure is a threat to the margins of food-processing firms, retailers and restaurant owners, and could mean price changes.

A geopolitical dimension as well. Droughts combined with shipping disruptions or export restrictions could cause higher vulnerability for countries relying on concentrated agricultural import markets. Food security is therefore increasingly gaining the importance of economic sovereignty. Countries with strategic reserves, a diverse supplier base and investments in climate-smart agriculture will have a significant advantage.

Hence, agricultural adaptation has to be made a national security and economic priority for India. Spending on irrigation efficiency, heat-resistant seeds, cold-chain equipment, crop insurance and storage infrastructure and on reliable weather forecasting should be considered in the context of the costs of consecutive crop failures. Improvements in agricultural logistics can minimize wastage; and diversifying agricultural production can help minimize reliance on vulnerable crops.

The risk is not that all food items will ever be so expensive. Agricultural prices continue to be cyclical and a good harvest can offset individual price rises. What is more alarming, however, is the idea that more and more production shocks may keep average food inflation high and decrease price predictability.
