Hormuz Disruption Enters a New Phase as Bunker Delays and Air-Cargo Workarounds Spread

The latest Strait of Hormuz disruption is widening from a corridor-security problem into a broader freight execution problem. As of early May 2026, maritime security monitors still describe traffic through the strait as sharply reduced rather than normalized, carriers are maintaining booking restrictions and emergency charges, analysts are warning that today’s long bunker lead times in Asia could become a global standard if disruption persists, and cargo airlines are preserving route rights while adjusting Gulf-linked operations. Taken together, that marks a more operationally significant phase of the crisis than the earlier story of simple rerouting and booking suspensions.

What changed in early May

The most important update is not a formal declaration that the Strait of Hormuz is closed. It is that the region remains commercially impaired enough to keep global knock-on effects alive.

The UKMTO/JMIC regional advisory dated May 3 said traffic in the Strait of Hormuz “remains significantly reduced” and kept the regional threat level at critical. That advisory also reported a fresh May 3 attack on a northbound bulk carrier 11 nautical miles west of Sirik, Iran. Earlier JMIC updates documented multiple attacks or attempted attacks on container and cargo vessels in and around the strait and wider Arabian Gulf during April, including a container vessel attacked by a small craft on April 22 about 15 nautical miles off Oman, with the bridge reported heavily damaged by RPG and small-arms fire, and another container vessel hit by an unknown projectile on April 18 about 25 nautical miles northeast of Oman. The pattern described by JMIC is broader maritime disruption, not a single isolated transit event.

That distinction matters. A strait can remain technically open while still being operationally unreliable enough that carriers avoid it, insurers tighten terms, and network planners build workarounds around the risk rather than the charted navigability.

The bunker story is becoming global, not regional

The strongest new warning this week came from the Journal of Commerce, which reported May 6 that S&P Global analyst Fotios Katsoulas sees the roughly 14-day bunker lead time now in place at Asian hubs as a potential “global standard” if the disruption continues for another month.

That is a materially different story from earlier spring coverage that centered mainly on Singapore and Asian bunker tightness. If long lead times spread globally, the operational consequences compound quickly:

• vessels lose flexibility on where and when they can bunker;
• carriers may have to accept less efficient bunker calls or wait longer at fuel hubs;
• missed bunker windows can cascade into missed berth windows;
• schedule recovery becomes harder even on trades that do not call the Gulf;
• emergency fuel procurement costs get pushed into freight pricing through bunker surcharges, emergency fuel fees, or voyage repricing.

Carrier notices already show those cost pass-throughs are not theoretical. CMA CGM said in its March 10 emergency fuel surcharge advisory that bunker costs had risen “across all regions and trades,” and then increased those levels in a March 17 update. Maersk likewise introduced a temporary global Emergency Bunker Surcharge, explicitly linking it to fuel availability, fuel cost and fuel mix disruption tied to the Middle East conflict.

Hapag-Lloyd has gone a step further in some Gulf-related feeder markets. In an April advisory, it said that in addition to an existing emergency fuel surcharge, third-party feeder operators were imposing higher bunker-related operating costs, prompting a separate Emergency Operations Charge for shipments tied to ports including Jebel Ali, Abu Dhabi, Fujairah, Sohar, Salalah, Hamad, Dammam, Jubail, Kuwait and Umm Qasr.

Why longer bunker lead times matter operationally

Fuel is not just a commodity cost in liner shipping; it is a scheduling input. When prompt fuel availability deteriorates, operators lose one of their main tools for recovering disrupted rotations.

In practical terms, longer bunker waits can force carriers and charterers to:

Revise bunker-port selection

Ships may bypass a preferred fuel port in favor of whatever location can physically supply product sooner, even if that adds distance or cost.

Add buffer time into voyages

If the lead time to secure bunkers stretches from a few days to two weeks, vessel planners must lock in fuel decisions earlier and add more slack into rotations, reducing effective capacity.

Miss connection and berth windows

A delayed bunker stem can push a vessel outside its berth window or transshipment cutoff, creating second-order delays that spread well beyond the fuel port.

Layer surcharges

What begins as a bunker shortage can show up commercially as a bunker surcharge, emergency operations charge, war-risk premium, contingency routing cost or temporary storage fee.

That last point is increasingly visible in live customer advisories. In its May 4 Middle East operational update, Maersk said it was still avoiding Hormuz transit based on current risk assessments, maintaining booking suspensions for multiple Gulf markets, and applying an Emergency Freight rate on cargo loading from or destined to ports in Iraq, Kuwait, Bahrain, Qatar, the UAE and parts of Saudi Arabia and Oman to cover alternative routing, storage and other contingency costs.

The strait is not “normal” even if ports remain open

One reason precision matters in this story is that port status and transit viability are no longer the same thing.

On the one hand, Maersk’s port operations page still listed major Gulf terminals such as Jebel Ali, Abu Dhabi, Khor Fakkan, Dammam, Jubail, Umm Qasr, Bahrain and Sohar as open. On the other hand, the same carrier said on May 4 that, based on its own security reviews, transit through the Strait of Hormuz should be avoided for now. CMA CGM’s standing Middle East advisories have likewise referenced restrictions on maritime traffic and emergency measures affecting Gulf cargoes and vessel movements.

That is why the most accurate description at this stage is not a simple legal closure, but a market in which transit remains possible in principle while commercial operators, insurers and service planners continue to treat the route as highly constrained.

Air cargo is adjusting, but Gulf-linked resilience remains uneven

The air side of the story is more nuanced than the ocean side. The Journal of Commerce reported May 5 that global air cargo capacity has largely recovered to pre-shock levels and that international routes had not yet been seriously affected by jet-fuel shortages, citing Xeneta. That is an important headline signal: the global market has absorbed part of the shock.

But route-level recovery is not the same thing as network stability through Gulf hubs.

Xeneta said in an April market note that even after the ceasefire period, a full return to pre-conflict capacity and rates on trades transiting Middle East hubs would likely take one to two months. In an earlier analysis of the conflict’s air-cargo impact, Xeneta said regional air cargo capacity had remained about 30% below pre-conflict levels five weeks into the disruption, underscoring how concentrated the shock was around Gulf transfer hubs even when broader global capacity was recovering.

That helps explain why large operators are trying to preserve regulatory flexibility around Dubai-linked networks instead of assuming a quick snapback.

Why the FedEx waiver matters

A separate May 6 report from FreightWaves said FedEx had secured a war-related waiver tied to its Dubai cargo route so it would not lose route rights while pausing operations. Although the underlying FreightWaves article was not directly accessible in full during reporting, publicly available U.S. Department of Transportation filings show why such a waiver would matter.

In a prior DOT filing tied to FedEx’s South Africa authority, the carrier said it was using one allocated weekly frequency to operate a Boeing 777 via Dubai and Nairobi under its international all-cargo authority. That filing also underscored the regulatory importance of preserving route flexibility and operating rights in constrained markets. See the FedEx application in DOT-OST-2018-0162.

Operationally, the point is straightforward even if the exact waiver language is still not fully public: if a major integrator is taking steps to protect traffic rights while suspending or adjusting a Gulf-linked segment, Dubai is no longer functioning as a frictionless cargo bridge. The issue is not only whether aircraft can technically fly; it is whether schedules, route authorities, economics and contingency options remain dependable enough to support normal network design.

Risk is spreading beyond Gulf-destined cargo

The follow-on effects are no longer limited to freight actually moving into Gulf ports.

If bunker availability worsens, vessel rotations on Asia-Europe, trans-Pacific and other global services can still be affected through displaced demand for fuel, changed bunker-port selection, added insurance cost and reduced schedule recovery options. If Gulf-linked air cargo networks remain unstable, expedite options elsewhere become less dependable because lift must be reallocated and route structures reworked.

That is also visible in carrier contingency behavior. Maersk’s May 4 advisory kept in place booking restrictions across multiple cargo types, paused selected landside flows, expanded landbridge solutions across the Gulf, and said alternative routing and temporary storage were still required in many cases. Those are not the hallmarks of a market returning to ordinary schedule discipline.

What remains uncertain

Several points still warrant caution.

First, official public-source confirmation of the specific May 6 CMA CGM missile-strike report cited by secondary media was limited during reporting. UKMTO and JMIC have documented multiple recent attacks on container and cargo vessels in the region, but vessel identities are often withheld in public advisories. Without a directly attributable company statement or official incident notice naming the ship, it is safer to describe the broader attack pattern than to overstate incident specifics.

Second, the latest public evidence supports describing Hormuz as commercially constrained and high-risk, not conclusively or uniformly closed in a legal sense. Traffic remains heavily suppressed, carriers are avoiding transit, and contingency pricing remains active, but some terminals remain open and some freight continues moving via alternative combinations of sea, landbridge and transshipment.

Third, air-cargo recovery remains uneven. Global capacity may have broadly normalized, but the Gulf hub system still appears more fragile than top-line averages suggest.

What this means for freight planning now

For logistics teams, the immediate planning implications are practical rather than abstract:

• book earlier where bunker availability or Gulf transshipment could affect sailings;
• assume schedule reliability is weaker than published transit times imply;
• watch for layered charges, not just one headline surcharge;
• treat emergency airfreight through Gulf hubs as a narrower and less certain recovery tool than before;
• review whether critical shipments should avoid depending on a single transshipment or fuel-sensitive route.

For CAP Logistics readers, the clearest takeaway is that this is no longer just a Gulf-port access story. It is now a cross-modal reliability story in which vessel fueling, contingency routing, surcharge exposure and expedited-recovery options all deserve a fresh review for critical industrial freight, project cargo components and plant-support materials.
