THE shipping boom that has pushed earnings to unprecedented levels is colliding with the largest shipbuilding expansion in years, setting up a supply correction that could arrive later, but ultimately prove more persistent, than current delivery schedules imply.

That is the central market warning running through Danish Ship Finance’s latest bi-annual market outlook, which argues that unusually strong freight markets are increasingly reliant on disruption-created vessel demand at the same time as a 3.5-fold expansion in the global orderbook overwhelms available yard capacity.

For owners and investors, the implication is a market increasingly exposed at both ends of the cycle: today’s earnings can disappear faster than ships can be delivered, while the supply ordered into today’s boom is likely to arrive after some of the demand supporting it has disappeared.

The ClarkSea Index reached $80,300 per day in October, 67% above its 2007 peak and in its top decile for eight consecutive months — the longest such run since 2000.

But DSF’s analysis questions how much of that strength is structural. Across crude and product tankers, gas carriers and bulkers, approximately 1,800 ships are employed only because round voyages take longer than in 2019.

Almost half of that additional employment reflects longer-term trading shifts, particularly in dry bulk. But around 560 ships depend on the closure of the Strait of Hormuz and could theoretically return to the market within weeks of a reopening.

Crude tankers are particularly vulnerable. Nine in every 100 crude tankers are employed because voyages have lengthened since 2019, and eight of those nine are linked to the newest Hormuz disruption.

That demand risk is emerging immediately ahead of a substantial tanker delivery cycle.

The crude tanker orderbook stands at 26% of the existing fleet, while scheduled deliveries during 2027-2029 amount to 22.4% of today’s fleet. For VLCCs, the orderbook already exceeds the amount of elderly tonnage available for replacement: 33% of the fleet is on order against 20% aged over 20 years.

Even scrapping every VLCC over 20 would therefore leave that fleet 13% larger. If the roughly 60 VLCC-equivalent vessels currently employed because Hormuz is closed returned to the market as well, the effective supply increase would approach a fifth of today’s fleet.

Shipbuilding boom delays the reckoning

But the report’s wider shipbuilding analysis complicates the timing of the correction.

The global orderbook has expanded from 60m cgt in 2020 to 210m cgt in September 2026, while shipbuilding capacity has increased by only 30%, from 43.5m cgt to 56.4m cgt. Yards now have 3.7 years of production sold, compared with 1.4 years in 2020.

The headline orderbook, therefore, is a better guide to how many ships will arrive than when they will arrive.

Historically, only around 78% of scheduled tonnage has been delivered in its intended year. Most of the remainder is delayed rather than cancelled. Just 5%-7% of scheduled tonnage ultimately disappears.

That distinction is critical for market forecasts.

The yards are scheduled to deliver 61m cgt in 2027 and 64m cgt in 2028 against estimated global capacity of 56.4m cgt. Even applying historical delivery performance would leave yards operating at 84% and 89% of capacity respectively, before delayed ships from preceding years are added.

If 2027’s delayed tonnage simply shifts into the following year, Danish Ship Finance calculates 2028 deliveries could reach about 60m cgt, equivalent to 107% of current capacity.

The result is not necessarily less fleet growth. It is later fleet growth.

“The supply wave will arrive later and last longer than the orderbook shows,” the report, authored by DSF’s head of research Christopher Rex, concludes.

Supply pressure differs sharply by sector

The risks are also unevenly distributed.

Containerships face the largest scheduled addition, with tonnage equivalent to almost 32% of the existing fleet due during 2027-2029. Crude tankers face 22.4%, LNG carriers 27.5% and LPG carriers almost 25%. Dry bulk, by comparison, faces just 10.6%.

Gas carrier deliveries will peak first, in 2027, while the largest containership and crude tanker additions are concentrated in 2028-2029.

LNG carriers therefore face one of the clearest supply-side risks. An orderbook equivalent to 35% of the fleet is heading into a market where earnings are already in the bottom fifth of the range recorded since 2015.

Containerships face a different challenge. Their orderbook equals 36% of the existing fleet, with scheduled 2028 deliveries alone equivalent to 13.4% of today’s capacity.

For crude tankers, however, the timing potentially creates the most combustible combination: disruption-supported record earnings could normalise before the largest wave of new ships arrives.

China carries the delivery risk

The shipbuilding boom is also overwhelmingly concentrated in China.

Chinese yards built 32% of the ships currently trading but hold 69% of the world orderbook. Of the 149m cgt added to the global orderbook since 2020, 121m cgt, or 82%, went to Chinese yards.

The delivery schedules increasingly test that capacity.

China has 45m cgt scheduled for delivery in 2028 against estimated annual capacity of 32m cgt. Its scheduled crude tanker output that year is 4.3 times the most Chinese yards have ever delivered in a single year, while containership deliveries are scheduled at 2.4 times their previous record.

Some of that tonnage will inevitably slip.

But available capacity elsewhere offers only limited relief because shipyard capacity is not interchangeable. Japan has spare berths, for example, but much of that capacity is geared towards bulkers. LNG and VLCC construction remains heavily concentrated among already-booked yards.

Only 13 LNG carrier and 13 VLCC slots remain available globally for 2028, compared with 92 capesize and 71 medium range tanker slots. Significant capacity does not reopen until 2029-2030.

That scarcity is also supporting newbuilding prices, which remain within 3% of their 2008 record despite shipyards’ swelling forward books. DSF argues current prices increasingly reflect scarce berth availability rather than construction costs.

The danger for owners ordering at those levels is that the scarcity premium supporting newbuilding values today could erode just as the delayed ships finally reach the water.

The report therefore points towards an unusual cycle. Heavy shipyard workloads should restrict near-term fleet growth and potentially extend today’s strong markets. But they do not remove the ships that have already been ordered.

Instead, delivery slippage pushes more tonnage towards 2029 and beyond, increasing the likelihood that ships ordered into record earnings arrive into markets where disruption has eased, capacity has expanded and freight rates have already begun correcting.

For crude tankers in particular, that leaves a potentially uncomfortable sequencing problem: freight rates could react immediately to a Hormuz reopening, vessel demand could unwind within weeks, but the largest part of the newbuilding wave would still be coming.
