Introduction: How the Iran War is Reshaping Global Supply Chain Dynamics
The Iran war that erupted in early 2026 is having profound impacts on global supply chains, with repercussions extending far beyond the oil sector. This conflict has not only brought shipping through the Strait of Hormuz to a near-complete standstill but has also triggered comprehensive supply chain crises affecting everything from semiconductors to pharmaceuticals, from fertilizers to plastic feedstocks. As a critical chokepoint in global trade, the Strait of Hormuz handles approximately 20% of the world’s oil transportation, but more importantly, it serves as a vital corridor for Asian manufactured goods destined for European and American markets, as well as Middle Eastern petrochemical exports to global destinations. The prolonged conflict has paralyzed this lifeline, presenting the most severe test for global supply chains since the COVID-19 pandemic.
Supply chain experts widely agree that this crisis exposes the fragility of the global trading system. Professor Patrick Penfield of supply chain practice at Syracuse University notes, “This is really causing some major impacts within the global supply chain. As this conflict keeps progressing, you’ll start to see some shortages, you’ll see some major price increases.” This domino effect is spreading from Persian Gulf ports to major logistics hubs worldwide, testing corporate emergency response capabilities and supply chain resilience. In today’s increasingly globalized world, the impact of regional conflicts no longer remains localized but rapidly transmits across the globe through complex supply chain networks.
Strait of Hormuz: The Chokepoint of Global Trade in Paralysis
The Strait of Hormuz, located between Iran and Oman with its narrowest point measuring only 39 kilometers, represents the only maritime passage connecting the Persian Gulf with the Gulf of Oman. This waterway serves not only as the lifeline for Middle Eastern oil exports but also as a critical node in global manufacturing supply chains. According to estimates from Clarksons Research, which tracks shipping data, approximately 3,200 vessels (representing about 4% of global ship tonnage) are currently idle inside the Persian Gulf, with about 1,231 likely operating only within the Gulf. Additionally, around 500 ships (1% of global tonnage) are currently “waiting” outside the Gulf in ports off the coasts of the United Arab Emirates and Oman.
While these numbers may appear modest, their cascading effects cannot be underestimated. Michael Goldman, General Manager North America of CARU Containers, offers a vivid analogy: “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. 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.” This localized paralysis is rapidly diffusing through global logistics networks, creating congestion risks at ports from Singapore to Rotterdam, from Shanghai to Los Angeles.
The Domino Effect in Maritime Transport: From Persian Gulf to Global Ports
The shipping crisis triggered by the Iran war is generating complex chain reactions. First, vessels trapped in the Persian Gulf cannot complete their transport missions on schedule, leading to backlogs of ships waiting to unload at downstream ports. Second, vessels choosing to detour around the Cape of Good Hope to avoid risks are increasing congestion on alternative routes. Third, conservative scheduling strategies adopted by shipping companies to cope with uncertainty are further reducing overall transport capacity efficiency. These three factors compound each other, creating systemic pressure on the current global maritime system.
In response to this crisis, the Trump administration has proposed a plan aimed at restoring oil and trade flows through the Strait of Hormuz. President Trump stated on social media that he has ordered the U.S. International Development Finance Corporation 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. Trump further indicated 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, vessels previously used to escort merchant shipping in the area and in the Red Sea.
Critical Supply Chains at Risk: Chips, Pharmaceuticals, and Fertilizers Face Shortage Threats
The Iran war’s impact extends far beyond oil transportation. A wide range of products are shipped through the Middle East region. In addition to approximately 20% of the world’s oil originating from the region, products manufactured using natural gas—such as petrochemical feedstocks (used to produce plastics and rubber) and nitrogen fertilizers—also come from the Middle East. Pharmaceuticals exported from India and semiconductors and batteries exported from Asia to the rest of the world all transit through this region and could face significant delays.
The semiconductor industry is particularly vulnerable. The global chip supply chain heavily depends on Asian manufacturing and global distribution, with the Strait of Hormuz serving as a critical conduit connecting these two segments. Any shipping delays could slow global electronics production, affecting everything from smartphones to automobiles, from medical devices to industrial control systems. Similarly, India is one of the world’s largest producers of generic drugs, with its products primarily transported through Middle Eastern aviation and shipping hubs to markets in Africa, Europe, and the Middle East. Transport disruptions could lead to tight supplies of essential medicines globally, particularly in developing countries.
Fertilizer supply chains also face serious threats. The Middle East is a significant producer of nitrogen and phosphate fertilizers crucial for global agricultural production. Shipping delays could result in insufficient fertilizer supplies during planting seasons, potentially affecting crop yields and prices. These impacts will gradually manifest over coming months and could exacerbate global food security concerns.
Soaring Costs and Alternatives: The Economic Toll of Cape of Good Hope Detours
Beyond constraints on the Strait of Hormuz, the instability has dampened transit through the Red Sea and Suez Canal, which had just begun to see increased traffic after years of instability due to Houthi attacks on ships in the region. Shipping company Maersk had resumed transit through the Suez Canal and Red Sea but announced on Sunday that it was rerouting that traffic around Africa’s Cape of Good Hope—a move other companies have been making to avoid the volatile region.
According to estimates from Syracuse University’s Penfield, this detour adds 10 to 14 days to the journey and approximately $1 million in extra fuel costs per vessel. With higher fuel prices, longer routes, and increased risk in the region, shippers have begun adding fuel and “war risk” or “emergency conflict” surcharges to what they charge clients, leading to higher costs across the board. These additional expenses will ultimately be passed on to consumers, driving up prices for everything from electronics to food, from clothing to furniture.
More concerning is that these cost increases may prove persistent. Even after the conflict ends, shipping companies might continue charging risk premiums to compensate for potential losses from future uncertainties. Meanwhile, the Cape of Good Hope route, while avoiding conflict zones, increases carbon emissions and environmental impact—running counter to global efforts to reduce shipping’s carbon footprint.
Air Cargo Crisis: The Ripple Effects of Middle East Aviation Hub Closures
Air cargo has also been constrained. Closed airspace and airports in countries including the UAE, Qatar, Bahrain, Kuwait, Iraq, and Iran have stranded tens of thousands of people and cargo. The three major Middle Eastern airlines—Emirates, Qatar Airways, and Etihad Airways—all operate cargo aircraft fleets, and these carriers also transport goods in the belly holds of their passenger planes.
Goods transported by air typically account for less than 1% of all global freight by volume, but air-shipped products tend to be perishable or high-value items such as pharmaceuticals, electronics, and produce, which together represent about 35% of world trade value, according to Boeing’s World Air Cargo Forecast estimates. The longer these Middle Eastern airports remain closed, the greater the potential economic disruption if these sensitive shipments fail to arrive or must be rerouted around the conflict. Even before the Iran war began over the weekend, air freight carriers and airlines were already contending with closed airspace over Ukraine and Russia.
Flights through these Middle Eastern airport hubs constitute crucial routes for passengers and cargo from India. Henry Harteveldt, an airline industry analyst with Atmosphere Research Group, notes that reaching India has become difficult, with passengers potentially having to switch to different routes flying westward across Asia. Airlines may need to operate longer flights and, in some cases, even add fuel stops on certain routes. “Remember, there’s a lot of pharmaceutical products that are made in India and then exported to different countries around the world. If that’s disrupted, that has a huge, huge, huge impact,” Harteveldt emphasizes. Air cargo costs are expected to rise due to reduced capacity, increased demand, and surcharges.
Testing Supply Chain Resilience: Industry Adaptation to Multiple Crises
Despite the supply chain upheaval, Michael Goldman, General Manager North America of CARU Containers, believes the industry will adapt. Over recent years, it has faced other major disruptions including COVID-related supply shortages and other Middle East conflicts, becoming more agile. Goldman notes that companies have built better inventory buffers, diversified sourcing, and invested in technology to better track shipments and predict disruptions.
However, this crisis is distinctive in its multiplicity: it simultaneously affects both maritime and air transport, involves multiple critical sectors including energy and manufacturing, and has an uncertain duration. This demands more integrated response strategies from businesses. Some leading companies have already begun taking action: increasing safety stock levels, seeking alternative suppliers, adjusting production schedules, and even redesigning products to reduce dependence on affected regions. Digital supply chain management tools have demonstrated particular value during this crisis, enabling companies to monitor risks in real time, simulate different scenarios, and optimize logistics routes.
Supply chain finance also plays a crucial role. Political risk insurance, trade finance, and supply chain financing solutions can help companies manage cash flow risks, ensuring operational continuity despite shipping delays. Financial institutions are developing more flexible risk management products to address this new type of geopolitical risk.
Conclusion: Building Risk-Resistant Supply Chains for the Future
The Iran war’s impact on global supply chains serves as another reminder that in our highly interconnected globalized world, regional conflicts can produce worldwide consequences. This crisis has exposed the fragility of current supply chain systems but also provides businesses with an opportunity to reconsider their supply chain strategies. Future supply chains need to be more resilient—not only capable of withstanding shocks but also able to recover quickly afterward.
Building risk-resistant supply chains requires a multi-pronged approach: geographical diversification of sourcing, technological investment in digital tools, operational establishment of resilient inventory strategies, and organizational development of crisis management capabilities. Simultaneously, businesses must collaborate with governments, industry associations, and international organizations to collectively establish more stable and predictable trading environments. This crisis may also accelerate supply chain regionalization trends, with companies potentially favoring establishing production capacity closer to consumer markets to reduce dependence on long-distance transportation.
Ultimately, supply chain resilience concerns not only corporate survival but also global economic stability. In addressing the challenges posed by the Iran war, the global supply chain community has an opportunity to build a more robust, sustainable, and equitable trading system, better prepared for future uncertainties.
