Straight of Hormuz closure raises fertilizer prices for farmers, food shortages could happen as a result

Many farmers stock up early on fertilizer for next spring’s growing season. Last year, farmers who bought fertilizer in the fall were able to avoid the higher prices fertilizer saw in spring 2026, which rose when President Trump authorized the Iran war. This year, farmers won’t be able to avoid higher prices, Neal Burnette-Irwin reports for RFD-TV News.

“Fertilizer prices went up a lot this spring, but the one ... benefit to farmers is a lot of farmers had their fertilizer purchased earlier last fall before the prices really went up,” which helped them avoid impacts of higher prices in 2026, said Gregg Ibendahl, an agricultural economist at Kansas State University.

Since prices increased significantly this spring, they are likely to rise even more going into fall 2027, which means that this time around, there will be no cheaper season that farmers can use to "stock up."

One-third of the world’s fertilizer shipments pass through the Strait of Hormuz, which is currently closed due to the war, reports Josie Fischels and Xavier Walton for News Nation. “ICC Secretary-General John Denton says available fertilizer capacity has fallen nearly 40%, taking roughly 2.7 million tons off the market.”

 
Ibendahl said farmers will have to pay. Fischels and Walton estimate that farmers will pay 15.3% more on fertilizers this year. The high prices may mean food shortages in the coming months because high fertilizer and fuel costs are limiting what farmers can provide this season.
