Revolutionary Guard sets an LPG carrier ablaze and extends its threat beyond Hormuz

Iran’s Islamic Revolutionary Guard Corps said on Friday it had attacked a liquefied petroleum gas tanker in the Strait of Hormuz⁷. The IRGC navy issued a statement taking credit for a series of recent attacks on tankers², and warned that vessels “violating” its designated routes would be pursued and “punished” anywhere in the region⁴.

That last clause is the change. The Financial Times reported Iran attacking tankers beyond the Strait of Hormuz, while the IRGC insisted in a statement that it had control over the strait³. The claim of control is the Guard’s own, and it is contested³. Maritime Executive reported the threat as expanding against what the Guard calls non-compliant vessels².

The tempo has risen with the geography. A ship has been struck in the Strait of Hormuz nearly every day this month⁶. CNBC reported tanker attacks surging to a wartime high, with vessels transiting the strait coming under fire almost daily as Iran escalates in an effort to choke off a rebound in oil exports⁸. The tanker owners’ body INTERTANKO said in a weekly update issued on 9 October that attacks in the strait are continuing⁵.

Why it matters to investors

Freight is already repricing. Semafor reported that it now costs up to 77 million dollars to hire a large tanker to move crude from the US to Asia, up from less than 10 million dollars last year, as more crude passes through Hormuz¹. A threat that follows a ship out of the strait changes that arithmetic further, because the insurable risk no longer ends at the exit^3,4.

The second effect is on the volume that moves at all. If the aim is to choke off a rebound in exports, as CNBC reports, then what leaves the Gulf becomes a function of how credible the threat is held to be, not only of what is produced⁸. A near-daily strike rate is the kind of evidence that makes a threat credible⁶.

What to watch

Watch whether strikes are recorded outside the strait rather than inside it, which is the test of whether the extended threat is being carried out^3,4. Watch whether the near-daily rate USNI News describes persists through the rest of the month⁶, and what INTERTANKO’s next weekly update says about the pattern⁵. On the commercial side the charter rate Semafor cites is the cleanest single gauge of how the market is pricing the risk¹.
