Causal chain: US: port fees, maritime executive order, and MASGA package → Emission regulations (FuelEU, ETS, IMO) drive dual-fuel vessels → Orders bypass China and flow to Korea and Japan → Ex-China capacity down by one-third, slots booked to 2029 → Record newbuild prices, deliveries from expensive 2022-2024 backlog → Korean shipbuilders and Japanese suppliers: margin surge

While the market tracks every megawatt and every chip of the AI bull run, another structural deficit is quietly mounting: shipbuilding capacity outside China. Chinese shipyards possess capacity approximately 230 times larger than American yards and launch more than half of global tonnage. Washington has deemed this a national security vulnerability: in April 2025, the White House signed an executive order on rebuilding maritime power, in October port fees for Chinese-built vessels took effect, and the trade agreement with Korea included the MASGA package—$150 billion for shipbuilding cooperation. A ship is a 25- to 30-year asset, so even fee suspensions for a year (the effect of the Busan truce) leave a lasting risk premium: a shipowner planning decades ahead prefers to pay extra for a slot in Korea or Japan rather than risk their Chinese vessel becoming the target of the next tariff round.
The issue is that non-Chinese capacity is structurally constrained. Following a decade of bankruptcies and consolidation, active global shipbuilding capacity has shrunk by roughly one-third since its 2011 peak, and Korea itself shut down a significant portion of its docks after the 2015–2016 crisis. The result: the Seoul 'Big Three' have order books filled through 2028–2029, the newbuilding price index remains near all-time highs, and shipyards can cherry-pick contracts, prioritizing high-margin gas carriers and dual-fuel vessels.
