War Risk Insurance and Shipping Economics
Marine insurance is a critical enabler of global shipping. When insurers withdraw coverage or dramatically raise premiums, voyages become economically unviable even if physically possible — effectively shutting down shipping lanes.
- War risk insurance: A separate policy covering damage or loss of a vessel due to war, terrorism, or hostile acts. Standard hull and cargo policies exclude war risk.
- Lloyd's of London: The primary market for war risk coverage; sets benchmark rates that the industry follows.
- During the Tanker War (1984–88, Iran-Iraq War): Lloyd's progressively raised war risk premiums for Gulf voyages to several percent of hull value per voyage — making many voyages uneconomic.
- Current crisis (March 2026): Multiple insurers have entirely withdrawn war risk coverage for the Gulf region, meaning vessels cannot legally sail into the zone (most shipping contracts require vessels to be fully insured).
- Supertanker day rates (the daily rental rate for a VLCC): Hit all-time highs in March 2026 as the combination of vessel idling (150+ tankers outside Hormuz) and rerouting demand drives up rates for available tonnage.
- Insurance withdrawal → freight rate spike → higher delivered cost of oil → consumer inflation: This is the transmission chain from the geopolitical crisis to household fuel prices globally.
