Operational stability across major east–west container trades deteriorated sharply in 2025, as capacity churn reached unprecedented levels on Asia–North Europe, Asia–North America and Asia–Mediterranean routes.
In issue 745 of the Sea-Intelligence Sunday Spotlight, operational stability across Asia–North America and Asia–Europe trade lanes was examined using “operational capacity churn” – the total capacity entering and exiting a trade lane, serving as a measure of volatility and carrier deployment shifts.
Data for 2025 shows a major structural change, with carriers moving from stable vessel schedules to frequent, high-intensity capacity adjustments.

The trend is most pronounced on the Asia–North Europe route, where capacity churn reached 11.0 million TEU – 138 per cent higher than 2023 and far above the 3–5 million TEU seen between 2012 and 2019.
High volatility was also evident on Asia–North America and Asia–Mediterranean lanes. Asia–North America West Coast churn hit a record 10.4 million TEU, up 32 per cent from 2024.
Asia–Mediterranean reached 6.9 million TEU, an 80 per cent increase over 2023 and 21 per cent above 2024.

Asia–North America East Coast remained elevated at 6.6 million TEU, showing a steadier increase relative to other lanes.
These figures indicate that pre-pandemic vessel deployment stability has largely disappeared.
The once-predictable “cascading buffer,” where capacity flowed smoothly from primary to secondary trades, has been replaced by a highly dynamic system.
Vessels are now frequently rotated to match short-term demand fluctuations and navigate operational disruptions.
