Lloyd’s of London has rolled out a $400 million war-risk insurance facility to provide marine war risk coverage for vessels and cargo transiting the Strait of Hormuz. The new market consortium, led by insurer Chubb with support from Lloyd’s syndicates and specialist market partners, is designed to break a logjam in shipping through the strategic waterway.

The facility targets a critical bottleneck: roughly 20% of global oil passes through the strait, where recent attacks and seizures have driven up premiums and deterred some insurers from writing coverage. The consortium pools underwriting expertise and additional capacity to back transits that individual syndicates might avoid.

Chubb serves as lead underwriter for the facility, aggregating risk across multiple Lloyd’s syndicates. The structure mirrors historical war-risk pools, but with a specific focus on the Iran-linked threats that have escalated since 2019—including drone strikes, mine-laying, and fast-boat swarms.

Geopolitically, the move underscores deep unease about energy chokepoint security. Iran’s Revolutionary Guard has repeatedly threatened to close the strait, and the U.S.-led naval task force has struggled to guarantee safe passage. The facility offers a market-based workaround: by spreading risk, it lets cargoes and vessels move even as state-backed insurance from Tehran-aligned ports remains uncertain.

A counter_argument holds that insurance alone cannot solve the underlying security vacuum—tankers still face physical threats, and premiums may remain prohibitively high for smaller operators. Critics note the Gulf’s complex risk landscape may require naval deterrence, not just financial engineering.
