Strait of Hormuz disruption drives carrier suspensions and surcharges across Gulf gateways

A rapid escalation in maritime security risk around the Strait of Hormuz is cascading into concrete, near-term logistics constraints: carriers are suspending or restricting bookings into parts of the Gulf, war-risk and emergency fuel surcharges are multiplying, and contingency routings are re-shaping transit times and equipment positioning across Middle East gateways.

What changed—and when

By early March 2026, shipping traffic through the Strait of Hormuz fell sharply as operators reassessed risk and insurers tightened terms, according to reporting based on maritime and trade data. The situation has remained fluid through mid-to-late March, with policymakers publicly urging steps to restore freedom of navigation.

• On March 18, 2026, the Associated Press reported that most shipping traffic through the strait had been halted since early March, even as some vessels continued to cross and Iran continued exporting oil volumes. (AP coverage)
• On March 19, 2026, the Associated Press reported EU leaders calling for reopening the Strait of Hormuz and discussing options “to ensure freedom of navigation.” (AP coverage)

For logistics managers, the key point is that this is no longer a “risk premium” story alone; it is translating into booking controls, routing changes, and cost layers that are being formalized in carrier advisories.

Carrier actions: booking suspensions and formal advisories

Carrier advisories issued in early-to-mid March show a tightening net of restrictions around certain Gulf destinations.

A Maersk customer advisory dated March 6, 2026 outlines suspension of bookings to/from several Gulf countries and specific ports, while still accepting some bookings to alternative ports in the broader region. The document also references operational constraints tied to the evolving security situation. (Maersk customer advisory PDF, 06 Mar 2026)

Meanwhile, other carriers have moved to publish explicit surcharge mechanisms:

• CMA CGM posted an update for customers implementing an Emergency Fuel Surcharge effective March 16, 2026, citing sharply higher fuel prices following renewed volatility. (CMA CGM advisory)
• MSC published a War Risk Surcharge notice covering cargo moving from the Arabian Peninsula to multiple African and Indian Ocean destinations. (MSC advisory)

These moves matter because they are operationally “sticky”: once a carrier files and operationalizes a surcharge or booking control, it tends to persist until risk, insurance terms, and network plans normalize.

Ports: Jebel Ali disruption was brief, but it underscored vulnerability

One of the most visible port impacts was at Jebel Ali, the region’s biggest container port.

Multiple maritime-trade outlets reported that DP World briefly suspended operations at Jebel Ali following a fire linked to debris from an aerial interception, with terminal activity later resuming.

• The Maritime Executive reported that operations at Jebel Ali resumed after the brief suspension and placed the incident in the context of wider regional risk. (Maritime Executive)
• Ship & Bunker similarly reported a resumption of terminal activity after a precautionary halt. (Ship & Bunker)

Even if the Jebel Ali interruption was short-lived, it is operationally significant: the incident demonstrated how security events can generate immediate berth/yard disruptions and force carriers and cargo owners to reassess dwell time, cutoffs, and transshipment plans through Gulf hubs.

What this means operationally (next 2–6 weeks)

1) Longer and less predictable transit times

When carriers reduce exposure to Hormuz-adjacent calls, they typically respond with:

• Call omissions / blank sailings into affected ports
• Diversions to alternative regional gateways
• More transshipment moves (and therefore more handoffs and schedule risk)

Expect that even “moving” schedules may not translate to “reliable” schedules; ETAs and berthing windows can remain unstable when vessel rotations are being rewritten.

2) Higher landed costs from stacked surcharges

The current environment is producing layered pricing rather than a single surcharge:

• War-risk charges tied to insurance and security exposure
• Emergency fuel mechanisms tied to bunker price volatility
• Potential congestion-related charges when diversions concentrate volume into fewer hubs

CMA CGM explicitly tied its emergency fuel action to the fuel spike environment, with implementation from March 16, 2026. (CMA CGM advisory)

3) Equipment and capacity imbalances

If carriers avoid or reduce Gulf rotations, container equipment can accumulate on one side of the network. The practical implications often appear first as:

• Space constraints for exports out of the affected region
• Equipment shortages for inland repositioning (particularly for specialized gear)
• Rate volatility in spot markets as carriers triage which cargo to accept

4) Project cargo: higher risk of missed installation windows

For industrial projects depending on sequenced deliveries (power, mining, petrochem, construction), the risk is less about a single delayed container and more about misalignment of critical-path components. When a key leg is forced into transshipment or diversion, the probability of arriving out of sequence rises.

What remains uncertain

• Duration and enforceability of the disruption: Public statements and reporting indicate the strait has been “effectively” closed to a significant portion of commercial traffic since early March, but some vessels continue to cross, and conditions can change day-to-day. (AP, March 18, 2026)
• Insurance and underwriting behavior: War-risk pricing can shift abruptly after incidents, and some coverage changes can take effect on short notice.
• Network normalization timeline: Even if security conditions improve, it can take weeks to unwind vessel rotations, reposition equipment, and clear backlogs at transshipment nodes.

Why this matters for CAP Logistics readers

For CAP Logistics customers moving industrial inputs, spares, and project cargo through Gulf gateways—or relying on global ocean/air networks that indirectly depend on Middle East routings—the immediate priority is to treat March–April 2026 ETAs and budgets as subject to revision, and to plan for surcharge pass-throughs, rebooking cycles, and tighter documentation/booking cutoffs as carriers manage exposure and capacity.
