Extreme weather and soaring production costs are driving persistent global food price inflation.

Extreme weather and higher energy and fertilizer costs are disrupting food production and distribution, while a new analysis links weather-related price spikes across foods from seaweed to beef in 2022–26 with climate change. Wheat prices have risen amid concerns about Ukrainian port disruptions, Russian fuel shortages and European drought, though the global wheat outlook remains broadly adequate. Dry conditions and reduced plantings may leave South Africa needing more imports, while poor grass growth, frost damage and expanding dairy production in New Zealand could increase demand for imported grain and feed. Persistent rain has reduced vegetable deliveries in Tokyo and flooded sweet-potato fields, while landslides and blocked highways have cut vegetable arrivals in Kathmandu and driven up prices. In Ireland, drought and fuel costs are expected to push food inflation higher, with bread, flour and cereal prices forecast to rise by more than 10% by mid-2027 and dairy and meat also exposed. U.S. food prices rose 2.7% year over year through August, restaurant prices rose 3.4%, and beef prices are forecast to climb nearly 10% in 2026.
A New Zealand commentator said expanding kiwifruit plantings are raising questions about whether cool storage, support services and labor can keep pace. Separately, the conversion of about 30 Canterbury arable farms to dairying could contribute to grain imports rising and shortages of barley and wheat straw.
A Tokyo greengrocer said its roasted sweet potatoes have drawn customers from far away, including tourists, but the shortage forced it to turn away more than a dozen customers in one day. The owner estimated sales could fall by 30% to 40% if the store cannot sell the product for the rest of the year.
Irish consumers are already paying an average of 25% more for food than in January 2022. One contractor said harvesting an acre of maize, which cost about €1,000 in fuel last year, is now expected to cost close to €2,000.
The World Bank Group projected global commodity prices would rise 16% in 2026, while energy prices were projected to surge 24% and fertilizer prices 31%, illustrating how sharply farmers’ input costs could outpace crop-price gains.
