The war in Iran has sent oil prices soaring, which has a direct correlation with food prices. Energy is an essential input for the entire food supply chain, from farming and transportation to storage and retail. Additionally, the disruption to global fertilizer supplies due to the conflict has led to a 35% spike in urea prices, further increasing costs for farmers and food producers.

Why it matters

The food supply chain is incredibly delicate, and any disruption can have a ripple effect. The longer the war persists, the more drastic the impact on food prices. This highlights the interconnectedness of our global food system and the potential for widespread impact on consumers' grocery bills.

The details

Energy is required at every stage of food production, and this has a compounding effect on costs. Shipping, for instance, is a major energy consumer, and with diesel prices soaring, it's no surprise that this has a direct impact on delivery costs. The war's impact extends beyond energy prices, as fertilizers, a crucial input for farmers, are also affected. With over a third of global seaborne fertilizer traveling through the Strait of Hormuz, the disruption caused by the war has led to a 35% spike in urea prices.

  • The war in Iran has been ongoing since early 2026.
