**Summary**: The US confirms full implementation of a naval blockade in the Strait of Hormuz, with three carriers already in-theater, a second joining the blockade within days, and shoot-to-destroy rules for Iranian minelayers. Iran has reportedly attacked five merchant vessels and seized two, while Chinese nationals are urged to leave Iran. This materially escalates supply risk for Gulf crude and LNG, lifting energy risk premia and safe‑haven assets.

## Detail

1) What happened:
New statements and confirmations in the last hour significantly escalate the already critical situation around the Strait of Hormuz. The top US general (Caine) and War Secretary Hegseth state that the US is now "fully implementing" a blockade of Hormuz, with explicit rules of engagement to "shoot to destroy" Iranian units laying mines or threatening US shipping. CENTCOM confirms three US carriers are already operating in the Middle East, and Hegseth says a second carrier will formally join the blockade in days, indicating a prolonged, large‑scale naval posture. Concurrently, US officials report Iran has attacked five merchant vessels and seized two that had been authorized to transit the Strait. China’s embassy has advised its citizens to leave Iran, signaling rising perceived war risk and potential for broader sanctions or trade disruptions.

2) Supply/demand impact:
Roughly 17–20 mb/d of crude and condensate and a material share of global LNG exports transit Hormuz. Even before physical flow losses, insurance premia and freight rates will spike, and some shippers may reroute or delay liftings. Market will quickly price in the risk of partial or sudden disruption of exports from Saudi Arabia, UAE, Kuwait, Qatar, Iraq, and Iran itself. A credible near‑term scenario is temporary loss or delay of 1–3 mb/d due to self‑sanctioning, port congestion, or targeted harassment, with upside risk to a far larger disruption if combat escalates.

3) Affected assets and direction:
Brent and WTI futures should move sharply higher, with front‑end spreads widening (backwardation) and implied vol rising. LNG and European/Asian gas benchmarks (TTF, JKM) will gain on reroute and replacement risk. Tanker equities and freight indices (VLCC, LR2) likely rally on higher rates. Gold and JPY should benefit from safe‑haven flows, while risk assets in EM oil importers (India, Turkey) and their FX face pressure. USD could strengthen versus EM FX as global risk-off builds, but any perception of prolonged US conflict costs could temper this.

4) Historical precedent:
Episodes like the 1980s Tanker War and 2019 Gulf of Oman incidents moved crude several percent on far lower levels of explicit US–Iran confrontation. A declared US blockade plus confirmed attacks on multiple merchant ships is more severe and systemic.

5) Duration of impact:
This is not a transient headline. Carrier deployments, rules of engagement, and a blockade framework imply weeks to months of elevated risk premium, even if flows continue. If diplomacy (e.g., Iran FM’s trip to Pakistan, Oman, Russia) yields de‑escalation, some premium could retrace, but markets will price a structurally higher probability of future Gulf disruptions.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Dubai Crude, Gasoil futures, RBOB gasoline, JKM LNG, TTF natural gas, Qatar LNG-linked contracts, Oil tanker equities, Gold, JPY, EM FX of oil importers (INR, TRY, PKR), Gulf sovereign credit (Saudi, UAE, Qatar, Oman, Bahrain)
