Despite years of escalating prices and shrinking product sizes, food remains relatively affordable in most developed countries, accounting for approximately 10 percent of average weekly household expenditures in the United Kingdom, according to official data. This share has generally declined over several decades. However, mounting pressures on the agricultural sector worldwide suggest the era of cheap food may be nearing its end.

This summer’s extreme weather events across the northern hemisphere have underscored the vulnerability of global food production to climate change. Tens of thousands of hectares of farmland in continental Europe were ravaged by wildfires, providing a glimpse into future risks. Additionally, scientists and economists from the European Central Bank highlight the threat posed by an unusually strong El Niño weather pattern, which is expected to disrupt agricultural output across South America, Africa, and Asia in the coming months.

A recent study combining climate research and economic analysis estimates that by 2035, climate-related shocks could raise global food inflation by between 0.9 and 3.2 percentage points annually. This increase could, in turn, elevate headline inflation rates worldwide by 0.3 to 1.2 percentage points, presenting challenges for economic stability.

Apart from climate factors, farmers in the United States are confronting what some describe as the most severe downturn in four decades. The ongoing war has contributed to higher costs for fuel and fertilizers, while rising labor expenses, growing populations, and shrinking profit margins further squeeze agricultural producers. Analysts at UBS argue these pressures are creating a structural shift toward food inflation sustained at levels above the historical average of about 2.5 percent annually.

The implications extend beyond the agricultural sector. UBS research identifies over 100 publicly traded companies that could be affected by rising food prices. For example, Sweden’s Alfa Laval, a supplier of dairy farm equipment, might benefit from increased demand for efficiency-enhancing technologies. Conversely, retailers and hospitality chains such as Next and Accor could experience negative impacts if consumers reduce discretionary spending to manage higher food costs.

Broader economic effects are anticipated as well. Although central banks frequently monitor inflation measures that exclude food prices to guide monetary policy decisions, consumers’ perception of inflation often centers on grocery costs. Increased food prices could trigger greater wage demands, potentially prompting central banks to raise interest rates to contain inflationary pressures.

If food inflation remains persistently elevated, it would represent a structural economic shift comparable to transformative developments such as advances in artificial intelligence or the adoption of new pharmaceuticals. This evolution signals a complex interplay between agricultural markets, consumer behavior, and financial systems with significant implications for investors and policymakers worldwide.
