**Summary**: Iran’s IRGC and Khatam al-Anbiya HQ claim the Strait of Hormuz is closed, that naval mining has begun, and that two ‘violating’ ships have been struck. CENTCOM insists the strait remains open and that no U.S. warships have been hit, but U.S. airstrikes continue over southern Iran and the Hormuz area. The combination of formal Iranian closure claims, mining reports, and active combat over the chokepoint materially raises the oil and LNG risk premium even if traffic is still moving.

## Detail

1) What happened:
In the last hour, multiple Iranian military organs (IRGC Navy, Khatam al-Anbiya HQ) have issued statements declaring the Strait of Hormuz closed to all shipping and warning they will strike any vessel attempting to transit (reports 34, 39, 71, 101). Parallel reports state that Iran has begun large-scale naval mining of the Strait (28) and that IRGC naval forces claim to have attacked two ‘violating’ vessels (81, 107). U.S. CENTCOM explicitly denies the closure, asserting commercial ships continue to transit and that no U.S. warships have been hit (4, 18, 20, 32, 37, 60, 61). U.S. airstrikes are confirmed against coastal and Hormuz-adjacent targets (Bandar Abbas, Sirik, Bushehr, Dashti heights; 9, 11, 45, 52, 54), and jets have been operating over Qeshm/Larak islands within the strait area (14, 15, 40, 49).

2) Supply/demand impact:
Roughly 17–20 mb/d of crude and condensate and ~20–25% of global LNG exports normally pass through Hormuz. There is no verified, large-scale stoppage of traffic yet, but Iran’s formal closure order plus reported mining and claimed attacks on ships are enough for charterers, insurers, and navies to reassess risk in real time. Even a perceived probability increase of a partial disruption (say, 10–20% of flows at risk) is enough to drive a significant risk premium. We should assume near-term insurance premia/war-risk surcharges jump and some vessels delay or reroute pending clarity.

3) Affected assets and direction:
– Brent/WTI crude: Strongly higher; easily +3–10% intraday if markets credit any non-zero chance of real blockage.
– Dubai/Oman benchmarks and timespreads: Blow out on regional supply fears; prompt spreads move sharply into backwardation.
– LNG (JKM, TTF): Higher on transit-risk and knock-on European/Asian supply anxiety.
– Tanker equities and freight (VLCC, LNG carriers): Higher on war-risk rates; spot TD3C, MEG–Asia routes spike.
– Gold, JPY, CHF: Higher on broad Mideast war/energy-shock risk; VIX up.
– GCC CDS and high-yield EM energy credits: Wider on proximity and macro shock risk.

4) Historical precedent:
The closest analogues are the 1980s Tanker War and repeated episodes where threats to Hormuz (e.g., 2011–12, 2019 attacks on tankers and Abqaiq strike) spiked Brent several percent even without sustained volume losses. Markets tend to price the *option* of severe disruption quickly.

5) Duration:
The immediate price impact is risk-premium driven and could persist days to weeks as long as Iranian closure rhetoric, mining claims, and U.S.–Iran strikes continue around the strait. If evidence emerges of actual halted flows or damaged tankers, the shock becomes more structural; absent that, risk premium can retrace but will not normalize quickly while both sides keep Hormuz explicitly in play.
