Key Takeaways
- • Major maritime insurers and insurance mutuals have suspended or significantly repriced war-risk coverage for vessels transiting the Strait of Hormuz and Persian Gulf, with hull war-risk premiums jumping 25-50% and reaching double-digit millions of dollars per voyage as baseline annual policies historically priced in the hundreds of thousands of dollars.
- • The Joint War Committee of the Lloyd's Market Association expanded its "high-risk" designation to cover the entire Persian Gulf following Iranian threats to close the Strait and attacks on commercial vessels, forcing a structural reassessment of underwriting capacity in a chokepoint controlling approximately 20% of global oil supply.
- • Skuld, the world's largest maritime insurance mutual, issued a 72-hour cancellation notice for war-risk coverage in the region, signaling a sector-wide retreat from Persian Gulf exposures and creating a de facto private insurance market failure requiring government backstopping.
- • Marine war premiums are expected to remain elevated through year-end 2026, providing near-term margin support for insurers maintaining selective coverage, but the withdrawal exposes the limits of private insurance in systemic geopolitical risks and signals increasing government intervention in critical supply chain protection.
- • The repricing and withdrawal of private war-risk insurance reflects the inability of traditional marine underwriters to absorb large-scale, geopolitical systemic risks, pushing governments—particularly the U.S.—to directly intervene and guarantee coverage to preserve economic continuity in energy supply chains.
Summary
The marine insurance sector is experiencing a significant market dislocation as major underwriters withdraw or dramatically reprice war-risk coverage for commercial shipping in the Persian Gulf and Strait of Hormuz. Following Iranian threats to close the Strait and subsequent attacks on commercial vessels in response to U.S. and Israeli military action, the Lloyd's Market Association's Joint War Committee expanded its high-risk designation to encompass the entire Persian Gulf. This represents a structural shift in underwriting appetite as traditional insurers reassess their ability to absorb geopolitical systemic risk.
The financial impact on shipowners has been immediate and severe. Hull war-risk premiums have increased 25-50% according to broker assessments, with single-voyage premiums now reaching double-digit millions of dollars for vessels transiting the region. This represents a dramatic departure from the historical baseline model, where annual war-risk policies typically cost hundreds of thousands of dollars. Skuld, identified as the world's largest maritime insurance mutual, issued a 72-hour cancellation notice for Persian Gulf coverage, signaling that even cooperative underwriting structures view the risk as unmanageable under current premium levels.
The Strait of Hormuz carries approximately 20% of global crude oil supply, including over 40% of China's oil imports, making the disruption to marine insurance capacity a matter of critical economic infrastructure. Standard marine insurance policies exclude coverage for war-related losses under war exclusion clauses, which remove protection for large-scale geopolitical events that insurers cannot reliably underwrite. As private insurers retreat, the U.S. government has stepped in to backstop war-risk coverage, effectively converting what was traditionally a private insurance function into a government-guaranteed instrument to maintain supply chain continuity.
Despite the market contraction, London marine insurers continue to offer selective Middle East coverage at elevated pricing. Analyst expectations suggest that marine war premiums will remain elevated through the end of 2026, providing near-term underwriting margin support for insurers that maintain exposure to the market. However, the fundamental tension remains unresolved: private insurance markets operate on the principle of manageable, independent risks, whereas large-scale geopolitical events affecting critical global infrastructure represent systemic risks that exceed traditional underwriting capacity, increasingly requiring direct government intervention to sustain economic function.
