**Summary**: Iran’s IRGC says it has hit a third supertanker in the Strait of Hormuz in two days, setting it on fire after the vessel allegedly switched off AIS and ignored warnings. This materially escalates the risk of broader disruption to Gulf crude and product flows and reinforces a rising geopolitical risk premium in oil and shipping.

## Detail

Iran’s Islamic Revolutionary Guard Corps (IRGC) has announced it struck a third supertanker in the Strait of Hormuz within 48 hours, reportedly setting the vessel on fire after it switched off its navigation system and ignored warnings. Multiple tanker incidents in such a short span inside the world’s key oil chokepoint indicate a shift from episodic harassment to a sustained coercive campaign against commercial shipping.

From a supply perspective, no single tanker loss is systemically critical, but repeated attacks in Hormuz directly threaten around 17–18 mb/d of crude and condensate exports plus sizeable refined product and LPG flows from Saudi Arabia, UAE, Kuwait, Iraq and Iran itself. Even without a full closure, higher perceived transit risk will quickly translate into higher war-risk insurance premia, routing delays (e.g., slower speeds, convoy behavior), and possibly temporary charterer aversion to Iranian and nearby waters. This effectively reduces available tonnage and raises delivered crude and product costs, especially for Asia.

Markets will likely price a higher geopolitical risk premium into front-month Brent and Dubai benchmarks. A 3rd attack in 48 hours can justify several dollars per barrel in additional risk premium versus a calm baseline, with front spreads widening on fears of prompt disruptions. Product markets, particularly diesel and jet fuel in Europe and Asia, could also firm as traders anticipate any interruption of Gulf-origin cargoes amid already tight balances and ongoing uncertainty over Russian diesel export sanctions.

Historically, similar tanker incidents during the 2019 Gulf of Oman attacks and the 1980s Tanker War triggered 3–8% short-term spikes in crude benchmarks, even without a formal closure of Hormuz. The current situation overlays with already-elevated tensions and recent Western political commentary explicitly linking fuel prices to Hormuz risks, which may amplify speculative flows into oil and freight.

Unless there is rapid de-escalation or credible international naval protection, the impact looks more than transient. A days-to-weeks horizon of elevated volatility and higher risk premia is likely, with structural upside risk if attacks expand to LNG carriers or key export terminals.
