Iran war disrupts global ocean freight and air cargo supply chains beyond oil in International Shipping News 05/03/2026 The Iran war has effectively halted oil tanker movement in the key Strait of Hormuz. But it’s also disrupting the wider global supply chain beyond oil, affecting everything from pharmaceuticals from India, semiconductors from Asia and oil-derived products like fertilizers that come from the Middle East. Cargo ships are stuck in the Gulf or making a much longer detour around the southern tip of Africa. Planes carrying air cargo out of the Middle East are grounded. And the longer the war drags on, the more likely that there will be shortages and price increases on a wide range of goods. “This is really causing some major impacts within the global supply chain,” said Patrick Penfield, professor of supply chain practice at Syracuse University. “As this conflict keeps progressing, you’ll start to see some shortages, you’ll see some major price increases.” Stalled at sea Clarksons Research, which tracks shipping data, estimates that about 3,200 ships, or about 4% of global ship tonnage, are idle inside the Persian Gulf, but that includes about 1,231 that likely only operate within the Gulf. About 500 ships, or 1% of global tonnage, are currently “waiting” outside the Gulf in ports off the coast of the United Arab Emirates and Oman, according to the firm. While those may seem like small percentages, they have a domino effect that will lead to congestion elsewhere, said Michael Goldman, general manager North America of CARU Containers. “The supply chain is kind of like a long train with many cars and each car represents, let’s say, a port in the world. Well, if one car gets derailed, it can very often have a domino effect to many other cars behind it or in front of it,” he said. “So although we only have a small number of ports affected by this military action, it can really have a big effect on the total supply chain.” On Tuesday, President Donald Trump pitched a plan aimed at getting oil and trade moving again through the Strait. Trump said on social media he ordered the U.S. International Development Finance Corp. to provide political risk insurance for tankers carrying oil and other goods through the Persian Gulf “at a very reasonable price.” Political risk insurance is a type of coverage intended to protect firms against financial losses caused by unstable political conditions, government actions, or violence. Marine insurers had been canceling or raising rates for insurance in the region. He said that, if necessary, the U.S. Navy would escort oil tankers through the Strait of Hormuz. The Navy has at least eight destroyers and three, smaller, littoral combat ships in the region. These ships have previously been used to escort merchant shipping in the region and in the Red Sea. Computer chips, pharmaceuticals and other goods face delays A wide range of products are shipped through the Mideast region. Along with about 20% of the worlds oil that comes from the region, products made with natural gas such as petrochemical feedstock — used to make plastic and rubber — and nitrogen fertilizer come from the Middle East. Pharmaceuticals exported from India and semiconductors and batteries exported from Asia to the rest of the world are all shipped through the region and could face delays. Limited routes, higher costs In addition to constraints on the Strait of Hormuz, the instability has put a damper on transit in the Red Sea and
