**Summary**: Iran’s National Security Council chief stated the Strait of Hormuz will remain closed until the US changes its behavior and accepts Iranian conditions, reiterating earlier reports of a shutdown. This directly threatens transit of crude and refined products from Gulf producers and materially raises the geopolitical risk premium in energy markets.

## Detail

Iran’s Secretary of the Supreme National Security Council, Mohsen Rezai, has publicly declared that the Strait of Hormuz will remain closed until the US accepts Iran’s conditions. This is a senior, authoritative reiteration of an earlier Iranian line that the strait is shut, and it explicitly contradicts prior US political messaging suggesting a de‑escalation. Given that roughly 17–20 million bpd of crude and condensate and significant volumes of refined products and LNG normally transit Hormuz, any credible threat of prolonged disruption is capable of moving global benchmarks several percent.

At this stage, we do not have physical confirmation that shipping has stopped, but the combination of: (1) an explicit assertion that the strait is ‘closed’, (2) linkage to open‑ended political conditions, and (3) concurrent reports in the same news cycle of US–Iran maritime confrontations and attacks in the broader region, materially elevates perceived tail‑risk of an actual supply interruption. Even if flows are only partially impeded (delays, higher insurance, rerouting, self‑suspension by some shipowners), market participants will price a higher risk premium into the forward curve.

Immediate impact should be bullish for Brent and Dubai/Oman benchmarks, with potential intraday moves well in excess of 1–2% on headline risk alone. Time spreads in the front of the Brent and Dubai curves are likely to tighten (more backwardation) on fears of near‑term supply tightness. LNG and LPG markets with exposure to Qatari and Emirati exports may also see higher spot pricing and freight/insurance costs. Tanker equities and war‑risk insurance premia for Gulf routes should rise, while import‑dependent Asian refiners’ equities may underperform. The statement also reinforces safe‑haven bids in gold and could support the USD against EM FX with large crude import bills.

Historically, similar episodes — e.g., 2011–2012 Iranian threats to close Hormuz, or 2019 tanker attacks in the Gulf of Oman — produced sharp, if sometimes short‑lived, spikes in crude prices and freight rates. The duration of the current impact will depend on observed shipping behavior over the next 24–72 hours and any clarifying statements by Washington, Tehran, and Gulf producers. If traffic data and insurers indicate business as usual, the pure risk‑premium element may fade somewhat, but with a persistently higher floor for Middle East geopolitical risk until there is a visible diplomatic off‑ramp.
