After several years of elevated grocery prices, food inflation across the eurozone has slowed considerably during 2026, offering consumers a welcome period of relief. However, economists increasingly believe that the biggest inflationary threat for next year may not come from geopolitical tensions or energy markets, but from extreme weather. Persistent heatwaves and drought conditions across Europe are raising concerns about lower agricultural output, with analysts warning that reduced harvests could drive another round of food price increases throughout 2027.

Climate Risks Overtake Geopolitical Concerns

Earlier this year, markets feared that conflict in the Middle East would trigger higher food prices through rising oil and fertilizer costs. While those concerns have moderated following lower energy prices and easing fertilizer markets, economists now believe climate conditions present a more significant inflation risk.

Oxford Economics estimates that weather-related disruptions alone could add approximately one percentage point to eurozone food inflation next year, potentially pushing overall food inflation to around 3% during 2027. The firm argues that prolonged heatwaves and droughts are likely to reduce crop yields across Europe, placing upward pressure on the prices of fruits, vegetables, grains, and other agricultural commodities.

Although previous increases in oil and fertilizer prices may still contribute modestly to future inflation due to delayed supply chain effects, weather now represents the dominant uncertainty.

Food Inflation Has Improved, But Risks Are Building

Recent inflation data show meaningful progress. Eurozone food inflation declined from 2.5% at the end of 2025 to approximately 1.6% in June 2026, marking its lowest level in several years.

The improvement has been supported by favorable grain harvests, abundant dairy supplies, and easing prices for several agricultural commodities that experienced sharp increases during previous years. Falling olive oil prices, stabilizing cocoa and coffee markets, and lower energy costs have also reduced pressure throughout food production and distribution.

Oxford Economics expects these supportive factors to keep food inflation relatively contained during the remainder of 2026. Nevertheless, analysts caution that weather-related supply disruptions typically emerge after harvest seasons, meaning consumers may not experience the full impact until well into 2027.

Long-Term Inflation Could Be Increasingly Climate Driven

Beyond the immediate outlook, economists and central banks are paying closer attention to climate change as a structural source of inflation. Higher temperatures affect agriculture through reduced crop yields, increased irrigation needs, and greater production uncertainty, all of which ultimately influence consumer food prices.

Research referenced by Oxford Economics indicates that higher temperatures can continue affecting food inflation for up to a year after extreme weather events occur. Studies also suggest that future heatwaves may produce even larger inflationary effects as global temperatures continue rising, increasing crop vulnerability to heat stress and prolonged drought.

In addition, weather patterns associated with El Niño could further intensify agricultural disruptions if unusually warm and dry conditions persist across major food-producing regions.

Looking ahead, investors, policymakers, and consumers will closely monitor harvest results, weather developments, and agricultural commodity markets during the coming months. While food inflation has moderated significantly during 2026, climate-related risks are becoming an increasingly important factor shaping inflation expectations, monetary policy, and household spending across Europe and potentially other global food markets.
