The outbreak of war in the Middle East on February 28 has rapidly transformed the maritime landscape of the region, sending immediate shockwaves through global container shipping. Within only a few days of the conflict’s escalation, container movements into the region slowed dramatically and, in many cases, came to a near standstill.
According to maritime analytics firm Linerlytica, roughly 132 container vessels carrying an estimated 450,000 TEU of cargo are now effectively trapped within the Strait of Hormuz. On paper, this represents about 1.4 percent of the global container fleet, a figure that might appear modest in isolation. Yet in container shipping, the direct share of immobilized ships rarely tells the full story. The interconnected nature of liner networks means that even a small proportion of inactive capacity can generate ripple effects across the entire system, particularly if the disruption continues for weeks or potentially months.
The Strait of Hormuz occupies an extraordinarily sensitive position in the architecture of global trade. It functions not merely as a regional shipping corridor but as a strategic gateway linking the Persian Gulf to the broader Indian Ocean trade system. Container services operating in and out of Gulf ports are integrated into complex global loops connecting Asia, Europe, the Indian Subcontinent, and Africa.
As a result, the immobilization of vessels inside the strait extends far beyond the headline number of ships currently waiting offshore. Many of these vessels are components of larger service rotations that collectively account for approximately 3.4 million TEU of deployed capacity. When a vessel within a scheduled loop becomes delayed or trapped, the disruption cascades through the entire service string. Ports are skipped, schedules unravel, and subsequent sailings become misaligned. The operational disturbance may therefore affect close to ten percent of the global fleet through broken rotations, delayed repositioning, and disrupted port calls.
The strategic importance of the Persian Gulf itself further magnifies these effects. The region functions as a major transshipment and relay hub for containerized cargo, handling an estimated 650,000 TEU of weekly traffic. Ports in the Gulf play a critical role in redistributing cargo between long-haul intercontinental services and regional feeder networks. Among them, Jebel Ali stands out as one of the world’s most significant container hubs, processing close to 300,000 TEU per week and serving as a vital junction connecting East–West mainline routes with secondary markets throughout the Middle East, East Africa, and South Asia. When activity at such nodes slows or stalls, the disruption does not remain localized. Instead, it propagates outward along multiple trade corridors, affecting schedules and cargo flows across continents.
One of the immediate logistical consequences of the crisis is the displacement of cargo and the resulting imbalance in container equipment. Ships already en route to Gulf ports face limited options: they may wait offshore in hopes of a reopening, divert to alternative ports outside the conflict zone, or temporarily store cargo aboard until clearer instructions emerge. Each scenario generates inefficiencies. Containers discharged outside their intended destination create equipment mismatches, leaving large numbers of empty containers stranded in regions where they are not needed while creating shortages in export markets. Repositioning these containers later requires additional vessel space and operational resources, increasing costs for carriers and reducing overall network efficiency.
The pressure is added by the limited spare capacity available at many of the world’s largest transshipment hubs. A substantial portion of Middle East–bound cargo normally passes through major global terminals such as Singapore, Shanghai, Antwerp, and Tangier Med before continuing on feeder services into the Gulf. These hubs have been operating at high utilization levels in recent months, often reaching between 85 and 90 percent yard occupancy.
At such levels, terminals have little flexibility to absorb sudden surges in diverted cargo. When additional containers arrive unexpectedly, the result can be rapid congestion: vessels are forced to wait for berths, container stacks overflow yard space, and truck and rail operations slow as terminals struggle to maintain fluidity. In highly synchronized liner networks, even relatively minor congestion at one hub can propagate delays across multiple services.
The conflict also brings uncertainty surrounding one of the world’s most important maritime corridors: the Red Sea and the Suez Canal route. Over the past year, security concerns in the Red Sea had already forced many carriers to divert vessels around the Cape of Good Hope, dramatically lengthening voyages between Asia and Europe. In recent months, some shipping lines had cautiously begun reintroducing limited transits through the Suez route as security conditions appeared to stabilize.
The renewed instability in the broader Middle East, however, may once again push carriers toward the longer African routing. Sailing around the Cape of Good Hope adds significant transit time-often ten to fourteen additional days depending on the origin and destination-which effectively absorbs vessel capacity. Ships remain at sea longer to complete each rotation, meaning fewer voyages can be completed within a given timeframe. This tightening of effective capacity tends to place upward pressure on freight rates even when the physical fleet size remains unchanged.
Another dimension of the disruption concerns specialized cargo flows, including shipments linked to government logistics. Certain services connecting North America with the Mediterranean and Middle Eastern regions are operated by US-flag vessels that frequently carry government-related cargo. In times of geopolitical tension, governments often increase reliance on such vessels to move strategic supplies. Should this occur during the current crisis, a portion of available capacity may be redirected toward official cargo, further constraining space for commercial shipments.
For shippers, the unfolding situation bears striking similarities to the recurring disruptions that have characterized the container shipping industry since the COVID-19 pandemic. Over the past several years, supply chains have repeatedly encountered shocks-from port closures and labor disputes to canal blockages and security incidents. Each episode has demonstrated how quickly shipping schedules can deteriorate once network equilibrium is lost.
In the present case, shippers should expect a range of operational challenges including port omissions, declining schedule reliability, cargo rollovers, and mounting congestion. The effects will not remain confined to Gulf ports; once vessel rotations fall out of alignment, delays inevitably spread to regions that initially appear unaffected.
Freight markets have already begun responding to the turmoil. Rates on routes serving the Middle East have risen sharply in the immediate aftermath of the conflict. Carriers are also introducing additional contingency charges designed to offset the operational risks associated with the crisis. Mediterranean Shipping Company, for instance, has announced an “end-of-voyage” diversion policy that includes a surcharge of approximately for cargo requiring redirection. Such measures reflect both the uncertainty surrounding final destinations and the additional costs involved in rerouting vessels or holding cargo at sea.
Energy markets add another layer of complexity. The Strait of Hormuz is not only a container shipping chokepoint but also one of the most critical passages for global oil trade, with roughly one-fifth of the world’s petroleum shipments passing through the strait. Any prolonged disruption to tanker traffic could drive oil prices upward, which would in turn raise bunker fuel costs for shipping lines. Since fuel represents one of the largest operating expenses in maritime transport, higher bunker prices quickly translate into increased surcharges for cargo owners across multiple trade lanes.
Ultimately, the trajectory of the crisis—and its impact on global shipping—will depend largely on how long the disruption persists. Initial statements from US officials suggest that military operations could continue for at least three to four weeks, while some geopolitical analysts warn that the conflict could stretch for several months if regional actors become more deeply involved. Even a closure of the Strait of Hormuz lasting only one month would be sufficient to intensify many of the pressures already emerging: higher fuel prices, mounting congestion at transshipment hubs, growing container imbalances, and escalating transport costs.
At the same time, a disruption of this duration may still be too short for shipping lines to undertake structural redesigns of their global service networks. Instead, the industry would likely endure a prolonged period of operational turbulence in which vessels, cargo, and container equipment remain out of sync. Ships arriving late at one port will cause delays at the next, containers discharged in temporary locations will need to be repositioned, and carriers will continuously adjust schedules in an attempt to restore equilibrium.
If the conflict extends further, however, the cumulative effects could become more profound. Extended rerouting, sustained congestion, and rising costs may gradually reshape trade flows and freight markets across multiple regions. Global supply chains, already conditioned by years of volatility may once again find themselves navigating a complex and unpredictable environment where geopolitical events directly reshape the movement of goods around the world. In such circumstances, the disruption originating in a single strategic chokepoint has the potential to evolve into another systemic shock for the container shipping industry.
