Full history. Dashed line = 2025 average (0.00%/% hull).
War risk insurance is purchased separately from standard H&M (hull & machinery) coverage.
It covers losses from hostile acts, mines, torpedoes, and acts of war. Without it, no
commercial vessel transits a conflict zone — the financial exposure is uninsurable.
Key levels:
Normal (peacetime): 0.05-0.10% of hull value
Elevated (tension): 0.15-0.25%
Pre-crisis baseline (Feb 2026): 0.20-0.25%
Week 1 of crisis (Mar 1-7): 1.00% (5x baseline)
Week 2 of crisis (Mar 8-14): 3.00% (15x baseline)
VLCC cost at 3.00%: ~$7.5M per single transit (hull value ~$250M)

US DFC Reinsurance Plan: $20B facility announced Mar 11. Chubb as lead underwriter.
Covers hull, machinery, and cargo losses on a rolling basis. Has not restarted traffic —
physical threat remains the binding constraint.
Reinstatement timeline: Even if hostilities cease immediately, P&I clubs require
weeks of underwriting assessment, mine-clearance confirmation, and route risk evaluation
before resuming coverage. The commercial closure outlasts the military one by 2-6 weeks minimum.
