The escalating conflict involving the US, Israel, and Iran has severed a vital global shipping artery: the Strait of Hormuz. While skyrocketing petrol prices and surging domestic heating bills have dominated the headlines, the blockade threatens a much wider array of essential, everyday goods.
With daily shipping traffic plummeting from well over a hundred vessels to a mere handful, international supply chains are facing severe bottlenecks. From the food on our tables to the smartphones in our pockets, here is a look at the hidden casualties of the Hormuz closure.
A Looming Agricultural Crisis
The Gulf region is a global powerhouse for petrochemical-derived fertilizers, including urea, potash, ammonia, and phosphates. According to the United Nations, roughly a third of the world's fertilizer supply typically transits through the strait. Recent World Trade Organization data reveals that outbound shipments of these critical agricultural chemicals have virtually collapsed since the conflict erupted.
The timing could not be worse. March and April mark the critical spring planting season in the northern hemisphere. Researchers at the Kiel Institute caution that even a temporary closure could ruin an entire growing season, creating long-term food security nightmares. Estimates suggest global wheat prices could surge by 4.2%, with fruit and vegetable prices jumping by 5.2%.
Vulnerable nations are expected to bear the heaviest economic burden, with projected food price spikes of 31% in Zambia, 15% in Sri Lanka, 12% in Taiwan, and 11% in Pakistan. Meanwhile, major commodity producers like Russia—which already controls a fifth of global fertilizer exports—have signaled they are well-positioned to step in and fill the market void.
The Helium Shortage: Tech and Healthcare Under Threat
The conflict has also crippled the global supply of helium. Beyond its use in balloons, helium is a critical byproduct of natural gas extraction. Qatar normally exports a third of the world's helium through the Strait of Hormuz, supplying tech manufacturers who rely on the gas to produce semiconductor wafers for microchips found in computers, vehicles, and household appliances.
Following recent Iranian drone and missile strikes, Qatar's massive Ras Laffan gas facility has been forced to halt production. The Qatari government warns that repairs could take anywhere from three to five years, sparking industry fears of a long-term supply crunch and skyrocketing prices for cutting-edge electronics and data centers.
Crucially, this shortage extends into the medical sector. Liquid helium is essential for cooling the massive magnets inside hospital MRI scanners.
"MRI machines require somewhere between 1,500 to 2,000 liters of helium to cool the magnets. Every time you do a scan, a little bit of that boils off or evaporates," explains Prashant Yadav, a senior fellow for global health at the Council on Foreign Relations. "People like to think helium's predominant use is in data centers, semiconductors and cooling for the AI and data industry. But we can't forget that helium is quite important for MRIs and for other medical users."
Pharmaceutical Supply Chain Risks
Finally, the bottleneck at Hormuz threatens the production of life-saving medicines. Petrochemical derivatives, such as methanol and ethylene, serve as foundational ingredients for a vast array of pharmaceuticals, including antibiotics, painkillers, and vaccines.
With Gulf Cooperation Council states—including Saudi Arabia, Qatar, and the UAE—accounting for an estimated 6% of global petrochemical capacity, the sudden inability to export these raw materials could soon trigger a dangerous ripple effect of pharmaceutical shortages worldwide.
