The war in Iran poses risks to global fertilizer production and supply chains 🌍. The Gulf region hosts some of the world’s largest fertilizer plants, and roughly one-third of global crop nutrients pass through the Strait of Hormuz. While the US imports little fertilizer directly from Iran, it relies heavily on supplies from other Gulf countries shipping through the strait. Fertilizer prices—especially urea—have already risen amid disruption fears. Natural gas prices also moved higher after Qatar temporarily shut down a major facility Monday, adding pressure since gas is a key input for nitrogen fertilizer. Roughly 25% of global anhydrous ammonia exports and 20-25% of global urea exports move through the Strait of Hormuz. Many US fertilizer retailers pulled their offers yesterday due to the uncertainty.

The conflict is also influencing ag markets 🌽🫘. Soybean oil gained as much as 3.9% Monday as higher crude prices boosted biofuel demand. Soybean futures moved lower amid uncertainty regarding Chinese purchases and whether President Trump’s planned meeting with Xi Jinping later this month will occur as scheduled. Corn futures declined on concerns that disruptions to Brazilian shipments to Iran could reduce demand. Wheat futures were also lower as traders gave back last week’s gains while watching whether global grain shipments could be affected.

The conflict is beginning to impact gasoline prices ⛽. WTI crude surged 8.4% Monday to $72.74 per barrel after President Trump suggested the conflict could last longer than a few weeks. According to GasBuddy, the national average gasoline price rose 5 cents Sunday to $2.99 per gallon. The Strait of Hormuz is effectively closed, with tankers avoiding the region as insurers cancel vessel coverage. Shipping rates for oil and gas have surged, and continued disruptions could contribute to broader inflation pressures.

Brazil soybean production estimates were trimmed 🌱. AgRural lowered its forecast to 178mmt from 181mmt and reported harvest progress at 39% as of last week, well behind last year’s 50%. StoneX also cut its estimate to 177.8mmt from 181.6mmt. Both revisions were tied to drought conditions in Rio Grande do Sul.

US ethanol production reached a new all-time high last year ⛽🌽. Output climbed to 16.5 billion gallons in 2025, up 1.7% from the prior year, supported by strong domestic demand and record exports. The national average blend rate hit 10.5%, while domestic consumption increased to 14.3 billion gallons. According to the Renewable Fuels Association, growth reflects expanded E15 sales and could increase further if Congress approves year-round nationwide E15. US ethanol exports jumped 13% year over year to 2.2 billion gallons.

US corn shipments exceeded expectations for the fourth straight week 🚢. USDA reported 1.9mmt (73m bu) of corn inspected for export during the week ending February 26—down 8% from the prior week but up 37% year over year. Soybean shipments totaled 1.1mmt (42m bu), up 67% vs. the previous week and 62% above last year. China accounted for about 65% of inspections. Wheat shipments totaled 344,272mt (13m bu), down 39% week over week and 12% below last year. Roughly 12 cargoes of US soybeans were shipped to China last week—2 from the PNW and 10 from the Gulf—totaling about 30m bushels.
