The Strait That Changed Global Trade — Again
Six months ago, on February 28, 2026, US and Israeli forces struck Iran, and within 48 hours the world's most critical energy chokepoint went dark. Shipping traffic through the Strait of Hormuz has been largely blocked by Iran since February 28, 2026, when the United States and Israel launched an air war against Iran. The United States-Israel war on Iran has inflicted the greatest disruption to merchant shipping since the back-to-back shocks of the COVID-19 pandemic and Russia's invasion of Ukraine. For US importers and exporters, six months of rerouting, surcharges, mine threats, and diplomatic reversals have fundamentally changed how ocean freight is priced and planned. As of August 29, 2026, a new Iran-Oman framework has emerged — but the situation remains volatile, and no importer should be making routing decisions based on yesterday's headlines.
How the Crisis Unfolded: A Six-Month Timeline
The Iranian Revolutionary Guard Corps issued warnings forbidding passage through the strait, boarded and attacked merchant ships, and laid sea mines in the strait. Maersk, MSC, CMA CGM, and Hapag-Lloyd all suspended transits. Over 150 tankers anchored outside the strait rather than risk attack.
The United States and Iran agreed to a ceasefire in April 2026 and signed a June 2026 memorandum of understanding, but conflict resumed in July 2026 as Iranian forces launched attacks on commercial shipping deemed noncompliant with Iranian demands. A US-Iran memorandum of understanding reopened the strait toll-free from around June 17, 2026, but traffic stayed well below normal and the agreement broke down in early July after attacks on commercial vessels. The corridor has since returned to effective closure.
On July 14, Iranian missiles hit three tankers overnight, with one crew member killed and others injured or missing; the US reimposed its naval blockade the same day. On July 12, the IRGC declared the strait closed for a fourth time and the container ship GFS Galaxy was struck and abandoned.
Where Things Stand on August 29, 2026
Iran's deputy foreign minister announced a temporary shipping corridor in the Strait of Hormuz. Iran and Oman agreed on a temporary maritime route for ships travelling through the strait, but Iran warned that the waterway will not fully reopen until the United States fulfills its commitments under an interim peace deal signed in June, which has since lapsed. The transit corridor is 7 miles (11.3 km) wide.
As of August 28, Iran and Oman unveiled a Hormuz management framework including a temporary corridor and joint mine-clearing, though Trump's claim that all mines have been cleared was denied by the IMO as tankers continue to be hit, and the US pivoted to its toughest-ever sanctions on Iran.
US-facilitated transits through the southern corridor totaled 1,228 since June 20, with 37 occurring in the 48-hour period of August 25–26 alone. Since the July low point of approximately 4.5 transits per day, the rate has increased to around 18 per day during the most recent reporting period. That is still a fraction of the 88 to 130 daily transits the strait handled before the crisis. US-Iran diplomacy has effectively collapsed, removing any credible near-term pathway to full de-escalation.
What This Has Done to Freight Rates
The cost impact on ocean freight has been severe and multi-layered. The 2026 Iran war created what analysts called the largest supply disruption in the history of the global oil market by shutting down the Strait of Hormuz, the critical chokepoint for approximately 20% of the world's oil and LNG supplies. The conflict forced a massive rerouting of commercial vessels around the Cape of Good Hope, adding 10 to 20 days to transit times and spiking ocean freight rates by up to 50% for US importers.
A four-layer surcharge stack — War Risk Surcharge, Emergency Conflict Charge, Emergency Fuel Surcharge, and Peak Season Surcharge — has made base freight a minority of total cost. All-in quotes reached $8,250 to $9,500 per 40-foot high-cube container from Shenzhen to Jebel Ali, up 35 to 55% from July.
VLCC transit costs have now hit $20 million per voyage for the few operators still willing to risk the strait. Conflicting statements from Washington and Tehran highlight the widening diplomatic divide, making a near-term breakthrough increasingly unlikely. High-risk operators are exploiting a shortage of owners willing to transit Hormuz.
Even if negotiations progress, full restoration of pre-crisis free navigation at 95 to 138 transits per day is highly unlikely in the near term. The Middle East rate floor has structurally risen, and the high-surcharge structure on Middle East routes will persist at least into the fourth quarter of 2026.
The Red Sea Compound Problem
The Hormuz crisis did not arrive in isolation. One of the most significant aspects of this crisis is that it has occurred simultaneously with the resumption of Houthi attacks on vessels in the Red Sea, which began again on February 28, 2026. Suez Canal transits, which had been gradually recovering, dropped sharply once more.
Iran continues to target commercial shipping and Gulf states, while Tehran's Houthi partners in Yemen continue to threaten an expansion of the maritime conflict into the Red Sea. Attacks by the Iran-backed Houthi movement against Saudi Arabia-linked vessels and other energy targets in the Red Sea and Bab el-Mandeb corridor pose additional risks to maritime commerce and energy operations in the region. For US importers sourcing from Southeast Asia, the Middle East, or South Asia, neither the Suez route nor the Hormuz corridor currently offers a reliable path. Cape of Good Hope rerouting has become the operational standard, not an exception.
The Supply Chain Ripple Effects Beyond Energy
The Hormuz crisis is not just an energy story. Beyond energy, the crisis threatens global food security and semiconductor manufacturing by disrupting the supply of critical commodities such as fertilizer, sulfur, and helium. The Iran war could have a major impact on global supply chains by disrupting energy markets, delaying shipping routes, increasing transportation costs, and restricting access to key raw materials. Because modern supply chains are highly interconnected, even regional conflicts can create ripple effects that influence global trade and the price of everyday goods.
As analyst Peter Sand of Xeneta noted, the conflict will result in further weaponization of trade and will shatter hopes of a large-scale return of container shipping to the Red Sea in 2026. Cargo insurance costs have risen sharply, and many carriers continue operating under force majeure clauses that shift liability risk back to shippers.
