**Summary**: Iran’s IRGC has struck a vessel 7.5 nm off Oman after it allegedly ignored new Iranian routing rules for the Strait of Hormuz, with Western militaries confirming a cargo ship was hit by a projectile near a UN‑approved route. This is a further kinetic enforcement step on top of earlier turnbacks and threats, materially increasing the risk premium on crude and product flows through Hormuz.

## Detail

1) What happened: Multiple reports indicate the IRGC Navy fired on a commercial vessel roughly 7.5 nautical miles off the Omani coast, close to the Strait of Hormuz approaches. Iran claims the ship transited via a route not approved by its self‑declared Persian Gulf Strait Authority and ignored verbal warnings. A British military update separately confirms a cargo ship was hit by a projectile off Oman near a UN‑approved route. Another report notes Iran has already informed the U.S. via a newly established Hormuz de‑confliction line that it “bombed a tanker.” This follows previously reported Iranian enforcement of new routing/fee demands and prior live‑fire incidents, with several tankers already turning back.

2) Supply/demand impact: Roughly 17–18 mb/d of crude and condensate plus ~4 mb/d of products and LNG transit Hormuz. Even a modest reduction in available insurance, higher war‑risk premia, and voluntary shipowner rerouting/pauses can effectively tighten seaborne supply by 0.5–1.0 mb/d in the near term as voyages are delayed, re‑routed, or cancelled. If owners start avoiding the UN‑approved route that has now seen a hit, realized flows could fall further, particularly for spot liftings out of Saudi Arabia, UAE, Kuwait, and Qatar. Physical differentials for prompt Middle East grades and freight (AG‑East and AG‑West) are likely to gap wider, with immediate upside pressure on Brent and Dubai benchmarks.

3) Affected assets and direction: Crude (Brent, WTI, Dubai) and key refined benchmarks (Singapore complex, European diesel) should see a positive price shock; tanker equities and AG‑linked freight indices likely rally on risk premia. Regional FX (IRR unofficial rate, GCC FX via CDS and curves) could show stress via wider sovereign spreads rather than spot moves (given pegs). LNG FOB Qatar may pick up a transit premium.

4) Historical precedent: Episodes in 2019–2020 (tanker attacks, drone strikes on Abqaiq) triggered 3–15% intraday moves in crude on similar perceived chokepoint risks even when physical disruption was limited. The new factor is Iran trying to institutionalize control and fees, with live fire as explicit enforcement.

5) Duration: As this is now part of a pattern (multiple recent strikes and turnbacks), the risk premium looks more structural than transient. Unless there is rapid de‑escalation or a multilateral maritime protection regime with clear rules that Iran respects, markets will likely price a persistent Hormuz disruption probability over weeks to months.
