Why global shipping is set to look 'remarkably familiar' after the Iran war

What the post-Iran-war shipping landscape actually looks like

The US-Israel war on Iran, which began on February 28, 2026, has inflicted the most serious disruption to merchant shipping since the combined shocks of COVID-19 and Russia’s invasion of Ukraine, according to Al Jazeera. For more than four months, commercial vessels faced attacks, lengthy delays and steep operating-cost increases across two of the world’s most important maritime corridors: the Strait of Hormuz, through which roughly a fifth of global oil and gas once flowed, and the Red Sea, where Iran-aligned Houthi attacks had already rerouted traffic since 2023. The June 17 memorandum of understanding between Washington and Tehran — under which the US agreed to lift its naval blockade of Iran in exchange for Tehran reopening the strait, and later to waive sanctions on Iranian oil for 60 days — has been the trigger for an unusually rapid snapback.

Al Jazeera reports that container capacity on Asia–US West Coast routes last week surpassed the pre-conflict record at 350,000 TEU (twenty-foot equivalent units, the standard measure of container ship cargo volume). Regional container capacity that had collapsed from 3.2 million TEU to 74,000 TEU by mid-June has already returned to pre-war levels on some routes, according to Xeneta, the ocean and air freight rate analytics platform. On Monday, Maersk and Hapag-Lloyd — the world’s second- and fifth-largest container lines — announced they would resume sailing through the Suez Canal for the first time since February, after reassessing security in the Red Sea.

Where shipping actually broke and where it bent

The damage has not been uniform. Oil and gas tankers are structurally dependent on the Strait of Hormuz because there is no sea alternative for reaching Gulf producers; Al Jazeera reports that, at the height of the conflict, traffic through the waterway fell to as few as two tankers a day, down from 120 to 140 daily vessel crossings before the war. Iran’s Islamic Revolutionary Guard Corps at times required transiting vessels to negotiate passage, with some ships reportedly paying as much as $2 million per transit at the peak of the crisis. Container shipping, by contrast, had the option of diverting around the conflict via longer routes, which is why the industry is now recovering far faster than the oil-and-gas segment.

How fragile the truce actually is

The snapback in container shipping is taking place against a backdrop of fresh escalation. On Monday, a Qatari LNG tanker, Al Rekayyat, caught fire in the Strait of Hormuz after being struck by an “unknown projectile” off the coast of Oman, according to the United Kingdom Maritime Trade Operations. Axios, citing US officials, reported that Iran’s IRGC fired at least two missiles at commercial ships on Monday night, and Reuters said a Saudi-flagged crude oil tanker was also damaged when the IRGC fired missiles. The following day, US Central Command said it had struck more than 80 targets in southern Iran with precision munitions over a roughly four-hour operation; Iran retaliated by saying it had targeted 85 US military sites in Bahrain and Kuwait, and the IRGC later reported shooting down a US MQ-9 drone. The US Treasury also moved to revoke the temporary suspension of Iranian oil sanctions less than 20 days after the MoU was signed, a step Iran’s chief negotiator Mohammad Ghalibaf called a “major violation” of the deal.

Oil markets reacted to the latest exchange by pushing Brent crude more than 3% higher, to above $76 a barrel, Euronews reported. Oxford Economics chief global economist Ryan Sweet described the durability of the June deal as the “key domino” for the second half of 2026 — if it holds, Brent could average in the low $70s and feed an “energy-driven disinflation tailwind”; if it breaks, the firm expects a second oil shock with knock-on effects for AI supply chains in Asia, central-bank policy and even US midterm elections.

Why it matters

Seaborne trade carries about 90% of global goods by volume, and the world’s largest container ships — each with capacity exceeding 24,000 TEU, roughly equivalent to 12,000 trucks, 2,240 cargo planes or 360 freight trains — have no genuine substitute at scale. That is why the shipping industry has historically bounced back from major crises at remarkable speed: Al Jazeera, citing BIMCO, notes that global container volumes fell just 1.2% in 2020 and had already surpassed pre-pandemic levels by January 2021, a contrast with global air travel, which took more than four years to recover. For consumers, the immediate stakes are visible at the petrol pump and in the price of anything shipped in a container — clothing, electronics, food and the semiconductors that underpin the AI build-out that financial markets have priced heavily through 2026. Oxford Economics forecasts global growth accelerating to an annualised 3.1% in the second half of 2026 from an estimated 1.6% in the first, contingent on cheaper oil feeding through to household incomes.

Where the reporting diverges

Sources broadly agree on the directional recovery in container shipping, but disagree sharply on the durability of the underlying truce. Oxford Economics puts the odds of a durable US-Iran deal at “a coin flip” and forecasts Brent in the low $70s, while Morgan Stanley’s mid-year outlook, published in May, expects crude to climb back to roughly $90 a barrel — a roughly $20 spread on the same peace process. The World Bank is more cautious still, forecasting Brent at about $94 a barrel this year and warning that global GDP growth will slow to 2.5% in 2026. Analysts cited by Al Jazeera also disagree on the cause of the latest vessel strikes: Tehran-based analyst Hossein Royvaran suggested the Qatari tanker may have strayed into an area where Iranian teams were clearing mines, while Arman Mahmoudian of the University of South Florida argued the available reporting — projectiles, missiles or drones rather than underwater explosions — points to targeted attacks on individual ships rather than a mine-denial campaign.

What to watch next

Three concrete milestones will determine whether the post-war shipping picture truly returns to its pre-war shape. First, the mid-July deadline embedded in the US-Iran memorandum: the deal commits to fully restoring Strait of Hormuz traffic within 30 days of signing, and Sweet has flagged a sustained return to 75% or more of pre-war crossings by mid-July as the threshold that would suggest the agreement is holding. Second, whether Maersk’s and Hapag-Lloyd’s renewed Suez transits stick or are reversed if Red Sea security deteriorates, which would test whether container lines are genuinely repricing risk or simply riding out a temporary lull. Third, the US tariff and sanctions calendar: Section 122 tariffs expire on July 24, with replacement Section 301 levies expected to push effective US tariff rates higher from late July, while the revocation of the Iranian oil waiver creates a new flashpoint with Tehran.

Punit Oza, head of Maritime NXT and a former executive director of the Singapore Chamber of Maritime Arbitration, told Al Jazeera that shipping will look “remarkably familiar” in five years because it is an industry driven by demand: “Ships do not sail because shipowners want them to; they sail because consumers somewhere want grain, iron ore, gas, or televisions.” Judah Levine of freight-booking platform Freightos said container shipping is likely to look “quite similar” to how it did before the war, with Dubai’s Port of Jebel Ali continuing as the region’s main hub. The durable legacy, in other words, may be less a transformed industry than a more explicit risk premium baked into the cost of doing business at sea — a price worth paying because, as Al Jazeera puts it, no other mode of transport comes close in capacity or cost-effectiveness.
