About
This issue brief examines how the 2026 Strait of Hormuz disruption has exposed the structural energy vulnerabilities of South Korea and Japan — two of the world's most fossil fuel import-dependent economies. Drawing on shipping, insurance, and energy market data, it traces how the collapse of war risk coverage, not physical obstruction, drove the near-total shutdown of strait transits, and how the resulting freight and price shocks are cascading through both economies. The brief argues that repeated energy crises reflect a structural pattern reinforced by public finance: both Korea and Japan have directed vastly more public funding to fossil fuel infrastructure than to renewables, deepening the very exposure that each crisis makes visible. It concludes with analysis of the transition opportunity — in renewable energy deployment, shipbuilding diversification, and public finance reform — and policy recommendations directed at KEXIM, K-SURE, JBIC, and NEXI.
Executive summary
Both Korea and Japan must fundamentally reorient their public finance institutions away from fossil fuel infrastructure and toward renewable energy and clean maritime industries.
1. Mandatory Energy Portfolio Risk Assessment and Disclosure.
Public export finance institutions (KEXIM, K-SURE for Korea; JBIC, NEXI for Japan) should conduct systematic risk assessments of energy-related finance portfolios — including geopolitical supply route risks, insurance volatility, and stranded asset exposure — with mandatory reporting to national legislatures.
2. Review of Public Finance for New LNG Infrastructure.
Reassess the economic rationale and stranded asset risks of continued public financing for LNG carriers, terminals, and upstream investments. Apply stress tests reflecting scenarios such as the current Hormuz crisis.
3. Expand Public Finance for Renewables and Clean Maritime Vessels.
Redirect public finance portfolios toward offshore wind installation vessels, alternative fuel carriers, and renewable energy infrastructure. Both countries' shipbuilding and maritime industries have the capacity to lead this transition — with the right finance signals.
4. Energy Independence Roadmap.
Move beyond import diversification to structural energy mix transformation — prioritizing domestic renewable energy deployment to reduce fundamental dependence on imported fossil fuels.
Key findings
The 2026 Hormuz blockade began with physical obstruction but it was the collapse of war risk insurance that caused the near-total shutdown: 7 of 12 P&I clubs (war risk insurance providers) cancelled coverage within 72 hours, collapsing strait transits by 81%.
Korea and Japan are among the world's most fossil fuel import-dependent economies: 70% and 90%+ of crude oil imports respectively originate in the Middle East.
In 2022, Korea's LNG spending nearly doubled (+96.5%) while demand barely changed (+0.9%). Japan's spending surged 65% even as demand fell.
Korea and Japan have directed $166 billion more in public finance to fossil fuels than to renewables over the past eleven years — capital that, redirected to solar, could have generated $500 billion in avoided fuel costs over 25 years: three times the original investment.
Korea builds 74% of the world's LNG carriers. UCL identifies Korea as the country most exposed to stranded asset risk in shipping finance. The transition to offshore wind vessels represents a $21-26 billion immediate market opportunity.
