Two maps of the same water
On Sunday CENTCOM's commander said Hormuz's main lanes were free of Iranian mines. On Tuesday Iran said another tanker hit one. Shipowners have to plan against both statements at once.
On Sunday, CENTCOM commander Gen. Brad Cooper said the main shipping lanes in the Strait of Hormuz were “safe and free of Iranian mines”1. On Tuesday, Iran’s navy said an oil tanker had struck mines east of the strait, caught fire and been damaged, after switching off its tracking systems and trying to enter a “restricted and unsafe” area2. It gave no name, flag, crew details or casualty figures, and did not say who laid the mines2.
A pattern of claims. Iran says this is not the first. The Revolutionary Guards said on Friday that two supertankers outside designated routes had hit mines; on Monday Iran said three more had1. Desk arithmetic: one plus two plus three is six tankers in about a week, if every claim is accurate, and none of the vessels in this latest case has been identified1. Tehran’s message is the same each time: the strait is “unsafe and closed” to ships that do not coordinate with its armed forces2. Its Hormuz authority also said it would take action against a shipping company, without naming which or what3.
What the market heard. Brent rose $1.48, or 1.3%, to $115.36 a barrel by 02:40 CET on Wednesday, Reuters reported, though that move followed the Houthis’ claimed strike on a Saudi refinery rather than the mine report3.
The temptation is to pick a side. You do not need to. A shipowner does not have to decide whether Gen. Cooper or Iran’s navy is right; the owner has to decide whether a war-risk underwriter will cover the voyage and at what price. That is why the most useful facts this week will be dull ones: a named hull, a classification society’s damage survey, a flag state’s casualty report. Statements set the mood. Survey reports set the premium.
Nothing here is investment advice.
What to watch
When two navies publish opposite charts, the cautious captain follows the insurer.
