Like most Saturdays at the Port of Long Beach, the morning of February 28, 2026, began with the sound of diesel engines threading through salt air, cranes moving, and containers stacking. Something had changed by the afternoon. Where ships should have been, gaps were visible on vessel tracking screens. Nearly one-fifth of the world’s traded oil passes through the Strait of Hormuz, a narrow passage between Iran and Oman that had all but disappeared.
Iran’s Islamic Revolutionary Guard Corps warned commercial ships passing through the strait that they were “not allowed” hours after coordinated strikes by the United States and Israel struck Iranian targets that morning. Within hours, vessel traffic reportedly fell by about 70%. This was not a far-off geopolitical event for shipping professionals watching AIS trackers from offices in Long Beach, Houston, and Newark. Arriving quickly, it was their operational reality.
What’s happening right now is the most recent development in a disruption story that has been developing for years; however, it’s possible that this chapter will actually change the map. Companies like Maersk and Hapag-Lloyd had already been forced to reroute ships around the Cape of Good Hope between 2023 and 2025 due to Houthi attacks on Red Sea shipping, which were largely attributed to Iranian support. This resulted in ten to fourteen days being added to Asia-European voyages and two to four times higher freight rates during peak disruption periods. These expenses were either passed down or covertly absorbed by American importers. The calculus is completely different now that the Strait of Hormuz itself is under scrutiny.
According to a 2025 UNCTAD report, the strait facilitates about 11% of the world’s maritime trade volume. The closure or significant disruption of that corridor causes more than just delays for American ports, which rely significantly on goods produced throughout South and East Asia. It entails large-scale rerouting, insurance premiums that have already increased by over 300 percent for ships passing through the Persian Gulf, and increases in freight costs that spread from each delayed container. Global freight costs increase by about $1 billion a year for every ten dollars that the price of oil per barrel rises. Procurement managers, who have been stress-testing precisely this scenario, felt a familiar, sinking weight as they watched the crude markets tick up on Saturday afternoon.
Trade analysts and port logistics operators feel that the industry had been secretly hoping that this specific escalation wouldn’t show up in quite this way. The Red Sea attacks, the COVID-19 pandemic, and the Russia-Ukraine conflict all sparked discussions in boardrooms about supply chain resilience, diversification, and “friend-shoring.” A few businesses took action. Many others waited, adjusted, and patched. The waiting seems to be over now. The era of hyper-efficient, single-source global logistics, which was predicated on the idea of stable maritime corridors, has structural limitations that geopolitics can reveal almost instantly, forcing multinational corporations to face an uncomfortable reality.
The ripple effects are already becoming apparent, particularly for American ports. Patterns of vessel calling are changing. On some lanes, reservations are being suspended. Importers who purchase consumer goods, pharmaceuticals, and electronics from Asian producers face challenging inquiries regarding lead times and stock availability that currently lack clear solutions. Although it’s still unclear how long the Strait disruption will last or how the diplomatic situation will change, the freight industry usually doesn’t wait for clarity because it prices in risk as soon as uncertainty arises, and there is a lot of uncertainty right now.
Looking at how this has played out, it’s remarkable how differently prepared various sectors seem to be. Some businesses that successfully managed the disruption cascade between 2020 and 2025 developed true operational depth, including scenario models, diverse supplier networks, and contracts with force majeure language that takes sanctions environments into account. Others are uncomfortably realizing that their supply chain flexibility was never as strong as it appeared to be. Right now, the businesses in the second group are the ones making desperate calls.
It’s difficult to ignore the fact that American ports, which over the past few years have transitioned from COVID backlogs to gradual stabilization, are now about to enter another phase of erratic, unpredictable cargo flows. Not only does the quieting of the Strait of Hormuz impact oil tankers, but it also reduces container shipping options throughout a vast area of international trade. The trade routes that American companies have depended on for decades are being renegotiated in real time, regardless of whether those companies are prepared for it or not.
