The commercial mechanism that will decide when the Gulf reopens is insurance, not the diplomatic track. Open-source reporting puts war-risk cover for a large tanker transiting the Strait of Hormuz at 3 to 8 percent of hull value, which is three to eight million dollars for a single transit. Before the war began in late February that figure was around 0.25 percent. It peaked near 10 percent, an increase of roughly 4,000 percent, according to Marsh.
The renewed attacks of late June have ended any near-term prospect of a reversal. The read across the market is that pricing eases slowly, if at all. Lockton's Rishi Thapar said the market 'is stabilising but not resetting' and will 'adjust gradually rather than sharply'. Underwriters at Policybazaar's UAE arm want 'two to four weeks of confirmed de-escalation' before lower risk feeds into pricing. S&P's Rahul Kapoor put the freeze plainly: transits are not happening because of the safety of the crew, the cargo and the vessel.
Two structural facts sit under the pricing. The strait's navigable lanes are only about three kilometres wide in each direction, and industry estimates put full mine-clearance at up to six months. A durable ceasefire and an end to vessel seizures are the preconditions underwriters name before capacity returns. Governments have propped up the market with a maritime reinsurance facility now expanded to around 40 billion dollars.
Operator implication: for any firm quoting or running Gulf-linked work, insurance cost and availability are the binding constraint, and they lag the headlines by weeks. A political thaw does not reopen the lane; confirmed, sustained calm plus mine-clearance does. Price contracts and movement plans for elevated premiums holding into the autumn, and build the insurance position into the risk assessment rather than treating it as an afterthought.
