Maersk and CMA CGM will terminate their cooperation on the ASAS2 service linking Asia with the East Coast of South America, with the final sailing under the joint arrangement departing Shanghai on 8 December 2026 as voyage 650W. Once that vessel sails, the ASAS2 loop will be discontinued outright rather than reassigned to another operator.

For shippers moving cargo between Asian load ports and Brazilian, Argentine and Uruguayan discharge points, the immediate practical consequence is limited but real: after 8 December 2026, bookings that previously rode on the shared ASAS2 string will need to shift onto Maersk's remaining network on the trade. Maersk has confirmed that its standalone ASAS service will continue operating normally as a fully Maersk-operated and controlled product, and that customers will still be able to book Asia–East Coast South America shipments through the ASAS network without interruption.

The decision hands Maersk sole operational command of its east coast South America coverage. According to the carrier, retaining full operational control will allow the company to manage and develop the service independently in response to customer requirements and market conditions. That phrasing signals Maersk intends to adjust capacity, port coverage and scheduling on the trade without needing to coordinate with a partner — a flexibility that matters in a lane where seasonal fruit exports, Brazilian manufacturing flows and intra-Asia feedering create uneven demand through the year.

For CMA CGM, the exit removes a vessel-sharing arrangement that had given the French line access to the ASAS2's port pairs under the cooperation with Maersk. The source material does not state whether CMA CGM will replace the lost coverage with its own tonnage or a new partnership on the Asia–ECSA trade. Shippers currently booked with CMA CGM on the lane should expect the carrier to communicate alternative routings as the December 2026 end date approaches.

The wind-down follows a defined chronology. Voyage 650W departs Shanghai on 8 December 2026 as the last voyage under the current arrangement. After that sailing, the ASAS2 service is discontinued. Cargo discharged from the final voyage will complete its rotation as normal. From that point forward, Maersk's ASAS service stands as the carrier's sole product on the trade, fully within its own network rather than shared.

For forwarders and BCOs, the operational takeaway is straightforward: any long-term contracts or rate agreements referencing the ASAS2 string need review before the December 2026 cutoff. Maersk's assurance of uninterrupted booking availability through ASAS suggests slot capacity will absorb transferred volumes, but shippers with space commitments on the joint service should confirm equivalent allocations on the surviving loop well ahead of the final sailing.

The split also fits the broader pattern of carriers consolidating control over their own products rather than maintaining shared strings. Maersk's stated rationale — independent management of the service against customer requirements and market conditions — points to a carrier that wants latitude to tune capacity and pricing on the Asia–ECSA lane on its own timeline. Whether CMA CGM responds with new capacity of its own on the trade, and how Maersk reshapes ASAS port coverage once it no longer coordinates with a partner, will define the competitive balance on the lane into 2027.
