Disruption to fertiliser supplies through the Strait of Hormuz is driving up costs and raising the risk of a global food crisis, particularly in vulnerable regions.

A top United Nations official on Tuesday warned that there is a real risk of a global food crisis if the Strait of Hormuz remains closed to shipments of fertiliser.

Jorge Moreira da Silva, executive director of the UN Office for Project Services (UNOPS), said in an interview with UN News that roughly one-third of global fertiliser shipments flow through the Strait of Hormuz, and its closure has caused “a massive disruption in the supply chain of fertilisers,” and “clearly we are seeing a crisis emerging” in the agricultural industry.

The UN official also emphasised the need for a fast resolution to the crisis to prevent catastrophic food shortages as tensions continued to escalate in the strait in recent days, with both the US and Iran seizing vessels in the area.

“We can’t wait until everything is fixed to at least get something fixed in time for the planting season,” he emphasised. “The planting season has already started, and in most countries in Africa it will end in May. So, if we don’t get some solution immediately, the crisis will be very significant and severe, particularly for the poorest countries and for the poorest citizens.”

While poorer nations are most vulnerable to fertiliser supply shocks, wealthy nations like the US are taking a hit as well.

A survey released last week by the American Farm Bureau Federation (AFBF) found that 70 per cent of US farmers say the price of fertiliser has grown so high that they will not be able to afford all they need for the 2026 planting season.

Analysis conducted by AFBF found that, since President Donald Trump illegally launched his war with Iran in late February without any congressional approval, “nitrogen fertiliser prices have risen more than 30 per cent, while combined fuel and fertiliser costs have increased roughly 20 per cent to 40 per cent.”

AFBF also found that the cost of widely used urea fertilisers “have increased by 47 per cent since the end of February, marking the largest month-to-month percentage increase” ever.

Zippy Duvall, president of AFBF, warned that “without the necessary fertilisers, we’ll face lower yields and some farmers will reduce acres altogether, which will impact food and feed supplies.”

An analysis published by Bloomberg’s Tracy Alloway on Wednesday found that “all the signs are already pointing to higher prices” for food in the coming weeks thanks to Trump’s Iran War.

“Bank of America’s Commodity Inflation Trendspotter for food and beverage companies shows March input costs up a whopping 373 basis points to 7.9 per cent year-on-year,” explained Alloway. “That jump was driven mostly by diesel and heating oil, meaning we haven’t even seen much impact from things like higher plastics prices or fertiliser just yet.”

Alloway pointed to the skyrocketing price of urea as particularly worrisome for food prices, as once Midwestern farmers start paying more for the fertiliser, “you start seeing higher prices for everything from actual grains to beef, chicken, eggs, ethanol,” and more.

The bottom line, Alloway wrote, is “rising fertiliser prices are now hitting farmers, and eventually those will translate into higher wholesale food prices which will (assuming higher costs are passed onto consumers) eventually land at grocery stores too.”

“The inflationary impulse doesn’t arrive all at once,” she added, “it builds.”
