The China–US West Coast container trade is attracting more capacity as its spot freight revenue per container per nautical mile outpaces other major export routes from Shanghai. Alphaliner’s 3 November weekly report puts the Shanghai–Los Angeles figure at about US$1.30 per 40-foot container per nautical mile, five times the US$0.26 generated on Shanghai–Rotterdam shipments routed around the Cape of Good Hope. MSC has deployed larger vessels on its Sentosa service, while ZIM is preparing another China–Los Angeles express loop. Their deployments illustrate different ways to capture the market’s strong revenues before changes in congestion, routing and fleet supply alter the balance.

Why the West Coast leads despite lower box rates

Alphaliner reports that Shanghai–US East Coast spot rates have remained above US$10,000 per 40-foot container since late August, compared with around US$7,500 to Los Angeles at the report’s reference date. Yet the approximately 5,775-nautical-mile voyage from Shanghai to Los Angeles produces about US$1.30 per container per nautical mile, against US$0.96 for Shanghai–New York shipments moving through the Panama Canal.

For carriers paying daily charter hire, financing and operating costs, the time committed to carrying a container matters alongside the price charged. With comparable speeds, utilisation and port conditions, a shorter voyage can combine a strong freight rate with more efficient use of vessel time. Alphaliner’s comparison shows how sharply this revenue measure differs across the main export corridors from Shanghai.

On these figures, Shanghai–Los Angeles generates approximately 3.8 times the revenue per container per nautical mile of Shanghai–Rotterdam via Suez, 2.6 times that of Shanghai–Genoa, and five times that of the Cape routing to Rotterdam. The gaps create a strong incentive to review deployment. The profit ultimately earned also depends on backhaul cargo, the mix of contract and spot bookings, and the full round-voyage cost of fuel, port calls and canal transits.

MSC adds scale while ZIM adds an express product

MSC upgraded its Asia–US West Coast Sentosa service in late August, replacing vessels of around 15,000 TEU with ships of approximately 23,600 TEU, according to Alphaliner. The replacement vessels offer roughly 57% more nominal capacity per ship.

Deploying larger tonnage on a high-revenue trade creates more slots to sell and an opportunity to spread costs across a greater cargo base. Realising those benefits requires sustained cargo volumes and terminals capable of handling the larger exchanges efficiently.

ZIM is adding a different product. On 30 October, it announced the exclusively operated ZX3 express service, scheduled to start in December on a Xiamen–Shanghai–Los Angeles–Xiamen rotation. The carrier advertises a 12-day Shanghai–Los Angeles transit and 15 days from Xiamen

Alphaliner gives a planned first departure from Xiamen on 6 December, with five ships of approximately 4,250–4,360 TEU assigned to the weekly service.

The ZX3 offering extends beyond the sea passage. ZIM’s announcement includes berth-on-arrival arrangements in Shanghai and Xiamen, a dedicated berth, yard and pickup lanes at West Basin Container Terminal in Los Angeles, and onward rail connections to US inland destinations.

For customers managing replenishment deadlines and inventory, berth access and the speed of discharge and collection contribute to the product’s value. Delivering an express service therefore requires coordination between vessel operations, terminal handling and inland transport.

MSC’s larger ships and ZIM’s express loop illustrate two commercial approaches to the same attractive market. One expands saleable capacity and pursues scale; the other competes through direct connections, shorter advertised transits and dedicated handling. Alphaliner reports that ZIM already deploys 52% of its capacity on the Pacific, making the new loop a further investment in a core market.

Each approach carries its own operating requirements: large ships need substantial cargo support, while express services need consistent delivery performance to sustain their positioning.

The cost and duration of the additional vessel commitments also matter. Strong spot earnings can support expansion, but the return on added tonnage depends on charter hire, the period for which it is committed and the flexibility to redeploy it later. Those choices reveal how carriers assess both the strength and the likely duration of the current opportunity.

COSCO figures show revenue growing faster than volume

COSCO SHIPPING Holdings’ third-quarter container shipping figures, reviewed in the same Alphaliner report, provide another view of the transpacific’s revenue strength. In the third quarter of 2026, transpacific revenue increased 61.2% year on year on cargo volume growth of 13.0%. Asia–Europe revenue rose 25.7%, while volumes grew 14.6%. Cargo growth was similar across the two markets, but the revenue gains were markedly different.

Calculated from those growth rates, average revenue per unit of cargo increased by approximately 43% on the transpacific, compared with about 10% on Asia–Europe. Pricing, currency translation and business mix all contribute to that result. It demonstrates how sensitive carrier performance can be to the composition of its network. Operators reporting similar volume growth may deliver different financial outcomes because their exposure to US trades, contract and spot cargo, customers and service products differs.

Fleet rankings capture the scale of an operator’s capacity; deployment and slot management influence the revenue that capacity earns. The choice of where to place an additional vessel, which ship it replaces and what service it supports can therefore be as consequential as fleet expansion itself. MSC’s upsizing and ZIM’s express launch are concrete examples of those decisions.

Shorter routes improve efficiency and release ships

The lower revenue per nautical mile on European routes also reflects the burden of longer diversions. Alphaliner estimates that sailing from Shanghai to North Europe around the Cape adds approximately 3,309 nautical miles compared with the Suez route. At the report’s spot rate levels, revenue per container per nautical mile is around US$0.26 on the Cape routing, against US$0.34 via Suez.

The extra distance spreads revenue over a longer voyage while consuming additional vessel time and fuel.

Returning to shorter routes can improve turnaround and reduce the number of ships required to maintain weekly departures. Alphaliner describes plans by the Gemini Cooperation of Maersk and Hapag-Lloyd to reroute its North Europe–India IOS/ME1 service through Suez in both directions. The change would shorten the round voyage from 12 weeks to 10, with 10 vessels maintaining the service.

Ships previously needed to cover the longer cycle can then become available for other deployment.

For an individual carrier, shorter voyages can reduce resource consumption. Across the market, a broad return to Suez increases the amount of tonnage available to operate services. Cost savings and additional supply can emerge together, with the eventual earnings effect depending on freight rates and where released ships are placed. A transpacific market that retains a substantial revenue advantage could attract some of the tonnage carriers are able to reposition.

At the newsletter’s reporting date, however, Alphaliner saw no immediate sign that the return to Suez was causing overcapacity. Heavy port congestion and disrupted schedules continued to absorb fleet efficiency. Alphaliner_NL_2026_11_03 Vessel supply therefore needs to be assessed through both fleet size and operating speed: shorter anchorage waits, improved terminal productivity and more stable schedules allow the same ships to complete more transport work. Effective capacity can recover even without an equivalent increase in nominal fleet capacity.

Latin America offers higher revenue with greater volatility

Some Latin American trades also offer stronger revenue per nautical mile than North Europe. Alphaliner puts Shanghai–Manzanillo in Mexico at approximately US$0.91 per FEU per nautical mile, close to the Shanghai–New York figure, while Shanghai–Santos generates around US$0.42. The volatility is substantial, however. Shanghai–Santos spot rates had fallen to around half their late-August level, while the Mexico trade’s revenue per nautical mile ranged from approximately US$0.70 to US$1.10 over the preceding six months.

These variations require carriers to weigh revenue against its durability. An attractive rate at a particular point can justify additional deployment, but the return after ships arrive depends on sustained cargo demand, backhaul utilisation and the ability to move tonnage when conditions change. A wider network also has commercial value in spreading exposure across regions and maintaining service for customers with multiple trade requirements.

More capacity will test the revenue advantage

The transpacific’s strong revenue performance creates an incentive for competitors to expand. MSC’s larger vessels and ZIM’s additional loop both increase the capacity offered by the relevant services. As more slots become available, cargo growth and utilisation will influence carriers’ pricing power. A prolonged period of high rates can encourage further commitments that gradually change the supply-demand balance.

That is the longer-term pressure behind Xeneta’s 2027 outlook, published on 5 November. It forecasts global container demand growth of 2.5%–4% and fleet growth of around 6.8%, with average spot rates across full-year 2027 falling 30% against a third-quarter 2026 baseline. Continued recovery of Red Sea and Suez routing is central to the forecast. A deterioration in security that forces vessels back around the Cape could instead renew upward pressure on rates. 

Strong transpacific revenues today and greater supply pressure next year describe different stages of the market. Congestion and schedule disruption are still consuming effective capacity. Continued rerouting through Suez, new vessel deliveries and improved turnaround would make more slots available, leaving demand growth to determine how much of the current revenue advantage survives.

The clearest signals will come from utilisation after new services and larger ships enter the trade, the capacity actually offered, and the efficiency of port and inland handovers. Carriers pursuing higher revenue also need enough flexibility in their vessels and cost commitments to respond when conditions change. For both MSC’s larger ships and ZIM’s express services, the eventual return will be determined by revenue, cost and turnaround across the complete round voyage.
