## Prediction

Within 24 hours, major marine insurers and P&I clubs are likely to issue updated guidance raising war risk premiums and possibly narrowing coverage for tankers transiting the Strait of Hormuz. Shipowners will face higher immediate voyage costs and may require charterers to absorb surcharges, pushing up delivered prices for crude and refined products into Europe and Asia. This will disproportionately impact smaller and lower-margin traders and refiners, while national oil companies with captive fleets will gain relative advantage. Confirmation would be broker reports of increased premiums, new Joint War Committee circulars, or charter party clauses citing Hormuz risks; disconfirmation would be explicit insurer statements keeping current pricing unchanged despite recent attacks.

## Drivers

- Iranian missile strike on Bahrain’s ISA Air Base fuel storage, demonstrating Gulf vulnerability
- Explosions reported in the Strait of Hormuz
- Iran’s announced plan to charge transit fees under its claimed sovereignty
- Historical insurer behavior after prior Gulf attacks on tankers
