Container ship overcapacity: BIMCO sees 9% fleet growth in 2027 as orderbook tops 14m teu

Container lines face a growing supply of ships just as the Strait of Hormuz crisis and Red Sea diversions that soaked up capacity start to ease on some routes.

BIMCO's outlook. In its September Container Shipping Market Overview and Outlook, published on 23 September and reported by gCaptain and Container News, BIMCO said:

• The global containership fleet has crossed 34 million teu, up 10 million teu in about five and a half years.
• More than 14 million teu is on order, around 42% of the existing fleet, and ship recycling is expected to remain limited.
• Fleet capacity is expected to grow 4.6% in 2026 and 9% in 2027.
• Global container volumes rose 5.1% in the first seven months of 2026.

BIMCO modelled two scenarios for 2027. If the Strait of Hormuz stays effectively closed, demand growth is forecast at 0.5% to 2.5%. If normal transit resumes, demand growth is 2.5% to 4.5%. In both cases ship supply grows faster, by roughly 5% to 6%. BIMCO added that if the gradual return to Suez continues through 2027, ship demand growth could be 5 percentage points below its forecast, and once routings fully normalise, ship demand could be about 10% lower than with continued Cape routing. BIMCO chief shipping analyst Niels Rasmussen said: "we expect that increased supply growth will drive a weakening of the markets during 2027."

Linerlytica's count is higher. ShipUniverse reported on 24 September that Linerlytica puts the orderbook at about 15.6 million teu across 1,925 ships, roughly 45% of the operating fleet. It cited Linerlytica estimates that port congestion ties up more than 11% of capacity, and that about 250 ships (3.5 million teu) remain on Cape diversions, down from a peak of about 380 ships earlier in 2026. ShipUniverse also reported that about 0.6% of the fleet was commercially idle in late August, with Alphaliner counting about 95 inactive ships.

Capacity is already being released. SAFETY4SEA reported on 1 October that capacity could move into surplus in the fourth quarter of 2026, which could mean more blank sailings and pressure on rates. Drewry's 1 October update said rising Suez transits are adding effective capacity on Asia-Europe, where spot rates have fallen for 12 weeks in a row.

Rate forecasts. Xeneta chief analyst Peter Sand said on 2 October that Far East to US spot rates have peaked for 2026 but will not collapse. He projects US East Coast spot rates of US$6,000 to 7,000 per FEU and US West Coast rates of about US$4,500 to 5,500 three months out, against US$11,523 and US$8,346 on 1 October. He called this "a sizeable correction" and warned that new disruptions could change the picture quickly.

• Today's high rates are propped up by disruption, not demand. Congestion, the Cape diversions and Hormuz are absorbing a large share of the fleet. As these ease, the new ships arriving will push the market toward surplus, according to BIMCO.
• 2027 contracts. Sri Lankan exporters negotiating annual or long-term rates for 2027 will be doing so in a market that forecasters expect to weaken. That is a forecast, and the timing depends heavily on Red Sea security and Hormuz.
• Watch for blank sailings. SAFETY4SEA noted that a surplus could mean more blank sailings. Cancelled voyages can change transit times and transshipment connections for Colombo cargo, even when rates fall.

1. Avoid locking in long contracts at peak levels without a review or index-linked clause. Ask your forwarder about rate review points in 2027 agreements.
2. Compare spot and contract each quarter, using Drewry, SCFI and Xeneta as reference points. See our early October rates update.
3. Ask about service changes. When carriers blank sailings or merge loops, check your transit times and transshipment ports.
4. Keep surcharges in view. Base rates can fall while war risk, fuel and peak season charges stay.
