Iran war's full impact on US grocery prices may take months to appear

Key Points:

• U.S. grocery prices rose 2.9% year-over-year in April 2026, marking the highest inflation rate for food eaten at home since August 2023, with overall food prices up 3.2% including dining out, according to the Labor Department.
• High gasoline prices driven by the Iran war and disruptions in the Strait of Hormuz have increased fuel costs, which in turn raise expenses for food production, processing, and transportation, though the full impact on retail prices may take several months to materialize.
• Other factors contributing to food price inflation include U.S. trade policies, such as a 17% duty on fresh tomatoes from Mexico, extreme weather conditions affecting beef and coffee production, and supply chain issues like bird flu impacting egg prices.
• Some food categories saw price declines or stability, such as milk, chicken, butter, and eggs, while fuel-dependent industries like shrimping face challenges due to high diesel costs limiting their ability to raise prices.
• Continued conflict in Iran may further increase food prices through rising energy, transportation, packaging, and fertilizer costs, potentially affecting planting decisions and food supply in the longer term.
