The queue is now longer than it was during Covid

Container shipping just set a record nobody wanted. Linerlytica, the industry consultancy that tracks vessel queues, put stranded global capacity at 3.92 million TEU in early September, equal to roughly 11 percent of the entire world container fleet sitting idle at anchor rather than moving cargo 1. By the following data cut that figure had climbed to 4.3 million TEU, pushing past the roughly 4 million TEU high recorded during the 2022 pandemic gridlock 2. That earlier record took a global lockdown to produce. This one has been built almost entirely by weather hitting two ports.

Shanghai and Ningbo-Zhoushan, the world's first- and third-busiest container ports, are the epicenter. As of early September, average vessel waiting time at Shanghai ran 5.46 days, with arrival delays averaging 6.41 days and departure delays 6.13 days; some berths were quoting waits of up to ten days 1. Roughly 135 to 139 vessels were queued at Shanghai alone in the same window, with another 100 or so stacked outside Ningbo 1 3. Yantian, further south, is caught in the same backlog.

Two typhoons in five weeks, and the system never reset

The proximate cause is a run of tropical storms that has hit China's east coast since mid-August, most recently Typhoon Saudel, which made a third landfall in the region in early September and forced fresh terminal closures on top of an already-swollen queue 4. Ports in China do not merely pause during a typhoon; they close entirely, and vessels already at sea keep arriving on the original schedule once operations resume. Each storm therefore adds a fresh wave of ships to a backlog that never had time to clear from the last one. That is the mechanical reason a weather event has produced a bigger dislocation than the supply chain saw during a global pandemic: Covid disrupted labor and demand over months, but it did not repeatedly slam the same handful of megaports shut for days at a stretch during the exact weeks carriers most needed throughput.

Freight rates are already repricing the mess

Spot rates out of Shanghai have moved first. Transpacific rates to the US East and West Coasts each rose roughly 9 percent week over week, with cargo bound for New York hitting a 2026 peak of $9,507 per forty-foot container and Los Angeles-bound boxes reaching an annual high near $6,802 5. Carriers are signaling more to come: the market is pricing in a further general rate increase of $500 to $1,000 per box effective September 15, layered on top of the current spike 5. East Coast rates carry an extra complication — draft restrictions on the Panama Canal are limiting an alternative routing option just as Gulf and East Coast carriers announce roughly a dozen blank sailings for the month, tightening capacity from the other direction 5.

Carriers are not simply waiting out the backlog; they are actively restructuring networks around it. Vessel-sharing alliances have begun omitting Shanghai port calls on some Asia-shuttle strings and adjusting broader east-west schedules to manage the queue rather than sail into it, a pattern logistics providers are already flagging to shippers as a live operational risk rather than a one-off disruption 6.

Who pays, and who is positioned to benefit

The timing is the real story for investors. This congestion is landing squarely inside the ramp-up for US holiday-season imports, the period when retailers most need predictable transit times and stable freight costs to stock shelves for November and December. Importers now face a stacked risk: higher landed costs from the rate spike, and schedule risk from a queue that has shown no sign of shortening. Retailers that front-loaded orders earlier in the year are better insulated; those still filling peak-season purchase orders are exposed on both price and timing.

On the other side of the trade, asset-heavy container carriers are the more direct beneficiaries. Blank sailings and port omissions function as de facto capacity discipline, and discipline plus a rate spike is a favorable combination for vessel operators' near-term margins, even as the same congestion signals softer underlying trade fluidity. It is the same dynamic that made shipping equities among the more volatile beneficiaries of an earlier 2026 rate cycle tied to Middle East disruption — a sector where operational chaos and operator profitability can rise together, at least until customers reroute volume or absorb the cost elsewhere 7.

What would actually break the logjam

Three things are worth watching into late September and October. First, whether Linerlytica's weekly stranded-capacity figure turns down or keeps climbing — a second consecutive increase would confirm the backlog is structural, not just storm debris working through the system 1 2. Second, the effectiveness of the September 15 general rate increase: if carriers cannot make it stick, it suggests demand is soft enough that congestion is masking overcapacity rather than reflecting genuine tightness. Third, and least discussed, is China's Golden Week holiday running from October 1 through 7, when port throughput nationally slows for the holiday even without any storm at all. A backlog of this size hitting a scheduled national slowdown before it has cleared is the setup for the congestion to still be the dominant Asia-Pacific shipping story when the Christmas import window closes for good.
