The Strait of Hormuz, the only natural maritime link between Oman and Iran, has been closed since March 2 after days of military strikes by the US and Israel resulted in Iran effectively closing the strait for the first time in history. Since then, vessels moving through the channel have been attacked and set ablaze, and hundreds of tankers remain stranded. The region's oil and gas production has made it one of the world's leading exporters of nitrogen fertilizers, which are essential to the global food system. Nearly a third of the global trade for nitrogen fertilizer passes through the Strait, while nearly half of the worldwide sulfur exports also travels through the corridor. Experts warn that if the war continues, the drop in supply and increase of cargo insurance premiums and freight rates could raise prices for everyone along the supply chain. The impact of the war is already evident, with prices for key fertilizer products increasing due to the war and expected to squeeze growers' profit margins.
