PARIS: Even as Gulf tanker traffic slowly resumes, the road back to normal food production will be long and arduous, given the war’s impact on fertiliser supplies, the UN has warned.

With factories shuttered and soaring gas prices driving up production costs around the world, fertiliser prices have risen across the board and are unlikely to fall back easily.

“If the Strait of Hormuz reopens immediately, i.e. not only a ceasefire but vessels moving, the impact would be significantly positive but incomplete and uneven,” the Food and Agriculture Organisation’s chief economist Maximo Torero said.

“The FAO is clear that damage has already been done.” According to Argus Media, the price of urea from the Middle East has, for example, risen by 70 per cent in a matter of weeks.

Gulf countries are major exporters of nitrogen fertilisers like urea, which provides plants with nitrogen to aid green leafy growth, as well as ammonia and phosphate.

Italy notably called last week for a “humanitarian corridor” in the Strait of Hormuz for fertiliser as Torero warned that if high prices continue, farmers would face a stark choice: “Farm the same with fewer inputs, plant less, or switch to less intensive fertiliser crops,” which would reduce food supply well into next year.

Torero warned the bottleneck in marine traffic since the conflict began on Feb 28 meant even if Hormuz were to reopen immediately, “infrastructure damage is not fully reversible in the short term”.

According to Kpler data, around 1.9 million tonnes of fertiliser are trapped on 41 vessels, equal to 12 per cent of all produce shipped out of the strait in 2024.

On March 2, an ammonia plant at Ras Laffan refinery in Qatar was attacked. Plants have also suspended or reduced production in the UAE, Saudi Arabia, Iran, Jordan and Qatar, whose Qafco complex accounted for 14 per cent of global trade in urea.

Overall, about one-third of urea trade has been choked off, says the FAO. In India and Bangladesh, nitrogen fertiliser plants have slowed down, unable to cope with the soaring cost of the gas required to operate.

Too late for some

He added many crop planting decisions have already been missed as the Northern Hemisphere is already in planting seasons, meaning those yields will not be recovered.

“It’s too late” in Pakistan, India, Bangladesh, Sri Lanka, Sudan, Kenya, Somalia, Turkiye and Jordan, all heavily reliant on Gulf fertilisers. But perhaps not for second harvests in Asia if fertilisers arrive within four to six weeks.”

He explained that “the time between a fertiliser shock and a harvest failure is measured in months. The time between a harvest failure and a food price surge is measured in months more. We are already inside that window.”

Ripple effect

Prices spiked following previous disruptions during the financial crisis of 2008 and the Russian invasion of Ukraine in 2022.

“I think what makes this one potentially more critical is the number of production hubs that are involved and countries that are involved,” says Sarah Marlow, global editor for fertiliser at Argus Media.

“And then the ripple effect has spread out from the Gulf to other countries, which have also been affected by a lack of raw materials, a lack of gas.”
