Container orderbook raises 2027 overcapacity risk for shippers

By Grace Kim

Global vessel orders stand at 16.2 million 20-foot equivalent units (TEUs), equal to 46.5% of the current global fleet, Linerlytica calculated last week. The delivery pipeline could outrun cargo demand in 2027, even as longer routings and port congestion absorb ships already in service.

How large is the delivery wave?

Alphaliner expects roughly 1,000 newbuildings carrying 8.5 million TEUs to enter the market in 2027 and 2028. This fall’s orders deliver mainly in 2029 and 2030. MSC, Maersk, Cosco Shipping and CMA CGM have either unveiled or been reported to order new ships in recent months, mainly for those later delivery years.

Sea-Intelligence’s analysis of the IMF’s biannual World Economic Outlook finds that demand may not absorb this capacity quickly enough. The IMF expects global trade volume growth to move from 4.6% this year to 4.7% in 2027, while advanced-economy import growth eases from 5% in 2026 to 4.2% in 2027.

BIMCO’s September outlook sharpens the mismatch:

• Fleet capacity: BIMCO projects 9% growth in 2027, after 4.6% this year.
• Supply versus demand: Effective supply should rise 5%-6%, against vessel demand growth of 0.5%-4.5%, even if Strait of Hormuz traffic normalizes.

A wider return to the Suez Canal would release still more capacity. BIMCO estimates full normalization would leave ship demand about 10% below the level currently required if vessels keep routing around the Cape of Good Hope.

Can effective capacity absorb the orderbook?

Head-haul demand, the first leg of a trading route, still outpaces capacity. Carriers also seek larger, more versatile ships with cleaner emissions profiles, though the reported order rationale names no emissions standard or certification.

Maersk CEO Vincent Clerc said on an August earnings call: “If I have a total market growing 4 percent but the head-haul demand is growing 7 to 8 percent, I need 7 to 8 percent more capacity every year just to be able to carry stuff.” His calculation supports continued fleet investment despite slower aggregate trade.

Maersk’s explanation is that headline fleet growth does not always become capacity where shippers need it. In an Oct. 5 blog post, Maersk’s Michael Britton, head of North America ocean product, said longer voyages and missed windows absorb capacity and spread disruption through terminals, rotations, equipment positioning and onward transport.

A Sea-Intelligence update from August estimated delays consumed 5% of deep-sea capacity, or 1.7 million TEUs, versus a 2.2% average from 2011 to 2019. The difference shows how operational constraints can mask nominal fleet growth.

Carriers can slow vessels or cancel sailings, and BIMCO expects slower speeds alone to absorb one percentage point of fleet growth in both 2026 and 2027. These levers do not remove tonnage; capacity returns if carriers accelerate vessels or restore sailings.

Maersk’s second-quarter report says demolitions neared zero for a sixth consecutive quarter. BIMCO records 10 million TEUs added over the past 5.5 years, against less than 300,000 TEUs removed, leaving limited immediate scrapping.

Only 16% of fleet capacity sits on ships aged 20 years or older, so the 2027 delivery wave has little old-vessel capacity to offset. Carriers must therefore absorb the wave through demand growth, route management and capacity discipline rather than demolition.

How do China-US tariffs redirect cargo?

China’s export resilience makes global trade volumes stronger than underlying container demand. After the United States implemented high tariffs in 2025, Chinese exports to the country contracted sharply; the United States has since largely scaled back those tariffs.

IMF data show Chinese exports to the US fell 22% from February 2025 to January 2026, while US exports to China dropped 25% over the same period. Yet outbound shipments of affected Chinese products to third markets rose to 52% of the trade at risk within one year.

Alan Murphy, CEO of Sea-Intelligence, said: “Overall trade volumes did not collapse, because the production went to other places.” The figures indicate rerouting and production shifts, rather than a simple contraction in goods crossing borders.

Manufacturers now send parts to Vietnam, Malaysia and Indonesia for assembly before shipping to the United States. Murphy said this keeps trade volumes steady but adds port stops, complicates logistics and raises costs.

Does AI cargo fill the ships?

The IMF said trade in AI hardware, including semiconductors and other computing components, has increased exponentially as a share of world GDP. Sea-Intelligence says the physical weight of those goods has barely grown, limiting their contribution to container tonnage.

That creates a gap between the value of containerized AI trade and the vessel volume it requires. Higher trade values therefore offer less tonnage support than the headline growth suggests.

What sourcing decision follows?

Carriers must decide how much slow steaming and blank sailing can bridge 2027 because the orderbook offers little demolition capacity to offset it. For shippers, the sourcing decision is whether to secure 2027-28 allocations before the delivery wave, using effective capacity rather than fleet headlines. Route plans must test Strait of Hormuz and Suez normalization, plus assembly routing through Vietnam, Malaysia and Indonesia, where extra port stops raise logistics costs.
