The Iranians have not and can not "close" the strait. Their navy is non existent and I suspect their fleets of small boats didn't stand up well to cruise missiles loaded with hundreds of submunitions (rather like lethal hail). They have mines, but it takes a pretty large craft to carry and set them. What is still a threat are the subsonic drones like the shahad. Many of those have been destroyed in their storage locations, but some are no doubt at firing points. As a result, they might be able to hit a tanker even if escorted.
As a result, it is the insurance companies that have effectively closed the strait. Hopefully some sort of convoy system can be established once the Iranian stockpiles have been further attritted over the next few days where destroyers are able to manage the odd attempt to strike a commercial ship.
Agree completely. Iran has not shut down the straits. Lloyds of London has. The straits are an actuarial problem. Until they reevaluate and reprice the risk on a per trip basis they remain closed to any ship owner who buys insurance.
