Somewhere in the Arabian Sea in late May 2026, a fully loaded container ship burned through fuel it had taken on 400 miles out of its way, at a price 60% higher than what the same bunker fuel cost just weeks earlier. That ship is not an outlier. It is the new normal for an industry absorbing an estimated $340 million a day in added costs as the U.S.-Iran conflict chokes off crude flows through the Strait of Hormuz, the narrow waterway that normally handles roughly a third of the world’s seaborne oil.
The cost estimate, attributed to the European think tank Transport and Environment via the Associated Press, reflects a crisis that has forced carriers to reroute vessels, pay sharply higher war-risk insurance premiums, and scramble for fuel at bunkering hubs already running hot. For consumers, the disruption threatens to push up the price of imported goods, from electronics to food, at a time when global supply chains had only recently found their footing.
The damage carriers are disclosing
The clearest window into the financial toll comes from the shipping lines themselves. Hapag-Lloyd, one of the world’s five largest container carriers, has said the situation is costing it roughly $60 million a week, a figure that covers both fuel and insurance. That single-company number helps calibrate the broader industry estimate: if one major operator is burning through $60 million every seven days, the aggregate daily hit across hundreds of carriers, tanker owners, and bulk operators starts to come into focus. Neither Hapag-Lloyd nor other major carriers have indicated when they expect normal operations to resume.
The mechanism behind the price spike is physical. Restricted transit through the Strait of Hormuz has cut off the heavier crude grades that refineries in the region depend on to produce bunker fuel, the residual fuel oil that large commercial vessels burn. Without those feedstocks reaching processing plants, marine fuel output drops even as demand holds steady or climbs. Fujairah, the UAE port that serves as the Middle East’s primary bunkering hub, is under visible strain. The 60% price increase reported in connection with the strait reflects that supply-and-demand squeeze, though the figure is drawn from market-level pricing rather than a single official benchmark and has not yet been confirmed by publicly available refinery production data.
What carriers are actually doing
Ship operators are not simply paying more at the pump. They are contending with the possibility that fuel may not be available at all on certain routes. When a vessel cannot bunker at its planned stop, it must either slow-steam to conserve reserves or divert to a port hundreds of miles off course. Both options add days to transit times and compound costs.
The fear of outright shortages has prompted some carriers to load extra fuel before entering the region, which raises a ship’s draft depth and can limit cargo capacity, creating a second layer of financial drag. Others are reshuffling their fleets, assigning newer, more fuel-efficient vessels to Gulf-linked routes and redeploying older tonnage elsewhere. Some captains have been instructed to reduce speed across entire voyages, even when bunkering is technically available, simply because prices at key hubs are so elevated that every ton of fuel saved matters.
These adjustments can soften the blow at the margins, but they cannot offset the structural impact of disrupted crude flows through one of the world’s most critical chokepoints.
What the numbers do not yet show
Several critical variables remain in flux, and readers should weigh the headline figures accordingly.
The $340 million daily estimate comes from a single organization. Transport and Environment is a respected Brussels-based research group, but no major industry body, not BIMCO, not the International Chamber of Shipping, has publicly confirmed or disputed the figure. That does not make it wrong, but it does mean the estimate has not been stress-tested against fleet-wide operational data that only carriers and port authorities hold. It is best understood as an informed projection, not an audited total.
The duration of the disruption is another open question. Neither Iranian nor U.S. officials have provided a firm timeline for when commercial transit will resume at normal volumes. Carriers are making routing decisions based on incomplete intelligence, and the gap between public statements and private military signals has left shipping executives guessing. Hapag-Lloyd’s $60 million weekly cost could climb or shrink depending on whether the strait reopens in days or stays restricted for weeks.
Insurance pricing adds a further layer of opacity. War-risk premiums in the region have jumped, but the exact magnitude varies by insurer, vessel flag, and cargo type. Hapag-Lloyd’s disclosed figure bundles fuel and insurance together without breaking out each component. Without granular data from Lloyd’s of London or other major underwriters, it is difficult to isolate how much of the industry’s daily losses stem from fuel costs versus the rising price of simply being insured to sail through contested waters.
There is also uncertainty about how evenly the pain is distributed. Larger carriers with sophisticated fuel-hedging programs and diversified route networks may be better positioned to absorb temporary spikes than smaller regional operators that lack bargaining power with fuel suppliers. Yet without a transparent breakdown of costs by company size, ship type, or trade lane, it is hard to know whether the crisis is primarily squeezing the industry’s giants, its smaller players, or both.
What this means for businesses and consumers
For companies that depend on ocean freight, the practical calculus is straightforward: build buffer time into delivery schedules and expect surcharges. Carriers have historically passed fuel cost increases to shippers through bunker adjustment factors, and the current spike gives them strong justification to do so. Importers moving goods through routes that touch the Persian Gulf or the broader Arabian Sea should be in contact with their freight forwarders now to understand which services are exposed, what contingencies exist if bunkering fails at a planned stop, and how quickly surcharges might be revised as conditions shift.
Consumers are unlikely to see an immediate, dollar-for-dollar translation of bunker costs into retail prices, but the pressure is real. Higher transport expenses tend to surface first in goods with thin margins and long supply chains: low-cost manufactured items, certain food products, and commodities that move in bulk. If the disruption persists into June 2026 and beyond, retailers may face a choice between absorbing costs, raising prices, or trimming product assortments, each option carrying its own risks in a still-fragile global economy.
Where to watch for signals
The most reliable indicators right now are not think-tank models or government briefings. They are the schedule changes, surcharge notices, and earnings guidance that major carriers publish in near-real time. When Hapag-Lloyd or Maersk adjusts a sailing rotation or revises a bunker surcharge, that is a company putting money behind its assessment of the situation. Those disclosures, combined with careful scrutiny of port throughput data from Fujairah and other regional hubs as it becomes available, offer the best map of a crisis still unfolding and of the mounting bill for keeping global trade moving while one of its key arteries remains constricted.
