Since September 2026, Asian ports have been holding a significant number of containers. This bottleneck affects a substantial portion of the global container ship fleet, with significant waiting times, and Freightos reported chronic congestion and delays in September 2026. Facing this immobilization, a growing number of shippers are switching to air freight, which is considerably more expensive than shipping by sea.
The essentials
- Since September 2026, a significant portion of the global container ship fleet has been immobilized in Asian ports.
- Waiting times are lengthening considerably; Freightos reported chronic congestion.
- Shippers are pivoting toward air freight, whose cost is considerably higher than maritime shipping.
- Low-value-added goods—textiles, food products—remain stuck in the maritime queue; only high-value industries (electronics, pharmaceuticals) can absorb the air freight premium.
- The congestion reveals an acute operational vulnerability of Asian hubs to disruptions, without by itself demonstrating a structural fragility that neither operators nor states have yet translated into a coordinated response.
The saturated docks
Asian ports concentrate roughly 70% of global containerized volume. This position is the result of four decades of massive industrial investment, a competitive workforce, and geography favorable to major maritime routes. Shanghai, Singapore, Ningbo, and Busan were designed to handle growing volumes, and they did so with sustained efficiency for years.
Since September 2026, something has changed. A significant portion of the global fleet was being absorbed by congestion, according to NYSHEX. To put that in perspective: it was less than the capacity operated by Maersk alone, and not the equivalent of the three largest shipping companies combined, stuck at anchor or at the quay, waiting to unload or load.
The causes are multiple and reinforce one another. Demand for imports to the United States remains strong despite economic tensions, while EU demand fell in the first quarter of 2026. Disruptions accumulated since 2021—Covid, the Red Sea crisis, drought at the Panama Canal—have desynchronized fleet rotations to the point that arrivals at major Asian ports now come in peaks rather than as a steady flow. Terminals are receiving a significant number of ships beyond their forecasts, and waiting lines are lengthening.
Sea-Intelligence, a firm specializing in maritime performance analysis, documents a decline in the punctuality of rotations on Asia-Europe and Transpacific routes. When a ship arrives several days late, it disrupts not only its own schedule, but also those of the ships following it. The desynchronization spreads in cascade over months.
Shippers do the math
For a consumer electronics manufacturer, the calculation is stark. Air freight is generally more expensive than maritime, but Freightos indices and quotes need to be compared on equal weight, volume, and conditions. The difference is absurd for televisions or machine tools. It becomes acceptable for semiconductors, medicines, or precision parts whose immobilization costs more than the transport premium.
This is exactly the shift that data is beginning to document. Air freight can be used for certain urgent shipments, particularly in high-value-added industries. A container stuck for several additional days in a South China port can lead to production shutdowns, contractual penalties, and crisis management. The air freight premium becomes a profitable option against the costs of disruption.
This mechanism is not universal. It favors first and foremost high-value-added industries—electronics, pharmaceuticals, luxury goods—which can pass the extra cost to customers or absorb it from their margins. Exporters of textiles, food products, and processed raw materials remain dependent on the maritime queue. For them, there is no profitable alternative. Their cargo waits, and so do their buyers.
This asymmetry is not economically neutral. It widens a resilience differential between supply chains. The supply chains of high-value industries adapt, at considerable cost, but they adapt. Low-margin sectors absorb congestion without a safety net. It is a silent recomposition of global industrial competitiveness, comparable in its logic to the documented effects of restructuring of mining supply chains: the best-positioned actors in the value chain absorb the shock; the others bear it.
A self-reinforcing disorganization
What makes this congestion particularly difficult to resolve is its self-accumulating nature. When a ship waits seven days at anchor before berthing, its containers arrive late at importers’ facilities. These importers increase their safety stock to avoid the next supply break. Their subsequent orders are larger and arrive in grouped flows. This behavior, rational at each actor’s level, amplifies peaks in port demand.
Sea-Intelligence has documented this phenomenon on Transpacific routes after each major disruption episode since 2020. Shipping companies attempt to compensate by adjusting rotations, by slowing ships to smooth arrivals, by diverting calls to less congested secondary ports. These adjustments come at a cost in fuel consumption and logistical complexity, and they are insufficient to clear an backlog of several weeks.
Drewry reports that port capacity in Southeast Asia—Vietnam, Thailand, Malaysia—has partially captured volumes diverted from major Chinese hubs. But these secondary ports lack comparable cargo-handling equipment, quay depth for the largest container ships, and rail and road connections to quickly move cargo inland. Partial diversion to these ports sometimes worsens overall delays rather than reducing them.
The lasting effects of 2026 congestion
Some industry observers estimated congestion could persist for several months. Sixteen months after September 2026 corresponds to January 2028. During this period, two trajectories are possible, and they lead to very different commercial architectures.
In the first scenario, Asian ports gradually absorb the immobilized fleet as unloading rates improve and rotations resynchronize. Congestion gradually clears over the following months, waiting times improve significantly, and the maritime-to-air cost differential returns to normal levels. Shippers who had pivoted to air freight return to maritime. The global commercial architecture does not change fundamentally. But the fragility remains entire: the system has shown it can seize up for over a year without a rapid correction mechanism, and nothing has been built to prevent the next disruption—a new geopolitical crisis in the Red Sea, prolonged drought at Panama, an unanticipated demand spike—from producing exactly the same result.
In the second scenario, the commercial adaptations currently underway could become durable. Shippers of electronics and pharmaceuticals who have invested in medium-term air freight contracts do not return to maritime for these volumes. Manufacturers who have diversified their suppliers toward countries closer to their markets, a trend already documented before 2026, accelerate this movement. Adaptations of commercial routes toward alternative modes could accelerate, to the benefit of economies whose high-value production can bear the logistical surcharge, and to the detriment of economies whose exports remain low-margin and dependent on the competitiveness of mass maritime shipping.
This second scenario represents a reconfiguration of global trade that favors some actors and penalizes others, without democratic arbitration or organized compensation. The geography of global trade then draws itself by default, as the outcome of operational decisions made by logistics professionals under pressure, and not as the fruit of deliberate trade policy.
Collective needs that no one is yet organizing
The 2026 congestion raises two questions to which markets alone respond poorly.
The first is redundancy. Global trade has been optimized for maximum fluidity at minimum cost. Asian hubs concentrate volumes due to historical factors of efficiency and cost. This concentration creates systemic vulnerability: when hubs saturate, capacity for overflow is limited and unequally available, though some hubs may reactivate capacity in the short term. Relief ports in geographically underequipped zones—East Africa, Central Asia, Eastern Mediterranean—would reduce this dependence.
These port investments are profitable over the long term, but their return horizon exceeds that of private actors alone.
The second is visibility. Data on the state of the global fleet and port delays exist, but they are fragmented among commercial paid sources—Drewry, Sea-Intelligence, Freightos—and inaccessible to small and medium-sized shippers who make their logistics decisions in the fog. A public mechanism for coordinating container flows in situations of critical congestion would allow all actors to arbitrate more efficiently. Initiatives exist at the national scale, notably in the Netherlands and Singapore, around shared port data platforms. None has yet reached the global scale needed to change the situation during a crisis of the magnitude of 2026.
The digitization of logistics, a subject that industrial SMEs are only beginning to address according to available data on actual adoption of digital tools in business, could provide part of the visibility infrastructure needed. But the connection between companies’ internal management tools and global port data platforms remains to be built.
Signals to watch through 2027
Two indicators will allow us to distinguish between scenarios in the coming months.
The first is the share of global fleet immobilized in Asian ports, measured monthly. If this rate drops significantly before the end of the first quarter of 2027, a resolution trajectory is likely. If it remains high, structural congestion is setting in.
The second is the evolution of the cost differential between maritime and air freight on Asia-Europe and Asia-North America routes. If the cost differential remains significant in favor of maritime, high-value shippers would have an incentive to maintain a portion of their volumes by air even after congestion clears. It is this partial maintenance of modal shift that would distinguish a durable reconfiguration from a simple disruption episode.
These signals are only useful when read over time. The logistics crises of 2021-2022 had seemed temporary during their first eighteen months before revealing deeper dysfunctions in the organization of global trade. The 2026 congestion deserves to be followed with the same analytical patience.
