**Summary**: Iran’s Khatam al‑Anbiya military HQ has announced closure of the Strait of Hormuz to ship traffic, citing US violations of a war-ending memorandum and Israeli strikes in southern Lebanon. Even if enforcement is partial or temporary, this materially raises the Gulf oil and LNG risk premium and threatens near‑term export disruptions.

## Detail

Multiple Iranian military and media channels report that Khatam al‑Anbiya Central Headquarters has ordered the Strait of Hormuz closed to ship traffic, characterizing this as a “first step” response to US non‑compliance with a war‑ending memorandum and continued Israeli operations in southern Lebanon. Several separate items (31, 32, 33, 43, 47, 54) all reiterate the same core point: Iran is declaring the strait closed for shipping, tying the move explicitly to Lebanon ceasefire violations and US commitments. This is on top of prior hours’ reports already flagging Iranian assertions of closure and early tanker rerouting.

From a market perspective, roughly 17–18 mb/d of crude and condensate and ~15–18% of global LNG trade normally transit Hormuz. Even if physical flows are not yet fully halted, the credible threat of interdiction, inspections, or harassment is enough to push a sizeable risk premium into crude, products, and LNG. Tankers have already reportedly turned back or adjusted routes earlier today, suggesting at least operational disruption and higher freight and insurance costs.

If Iran actively enforces the closure (boarding, live‑fire incidents, or mining), near‑term seaborne exports from Saudi Arabia, Iraq, Kuwait, UAE, and Qatar could be reduced by several million barrels per day until alternative routes (Saudi east‑west pipelines, UAE Habshan–Fujairah line) are maximized. Even a 1–2 mb/d effective outage or perceived risk of such for a few days historically has been enough to move Brent 5–10% (cf. 1980s tanker war episodes, 2019 Abqaiq attack risk repricing). For LNG, spotlight risk sits on Qatari volumes, which are heavily Hormuz‑dependent; TTF and JKM would likely gap higher on fear of tightening Atlantic Basin balances.

Beyond energy, this escalation feeds safe‑haven flows: gold typically benefits, while high‑beta EM FX in the Middle East comes under pressure. US–Iran negotiations in Switzerland are still mentioned, but one note suggests Araqchi’s trip may be cancelled post‑closure, underscoring a real risk that this is not pure signaling. Baseline: expect higher Brent/WTI and product cracks, firmer TTF/JKM, and rising implied volatility across energy until there is clear evidence either that Hormuz traffic is normalized or that Iran has walked back enforcement.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Gasoil futures, RBOB gasoline, Qatari LNG-linked contracts, JKM LNG, TTF natural gas, Tanker freight indices (MEG-Asia, MEG-Europe), Gold, USD/IRR, GCC FX and CDS (e.g., Saudi CDS, Qatari CDS)
