**Summary**: Iran’s Khatam al-Anbiya HQ and IRGC Navy have announced the immediate closure of the Strait of Hormuz to all vessel traffic, warning that any ship attempting transit will be targeted. IRGC statements and Iranian media now claim two vessels attempting ‘illegal passage’ have been struck. This is a major supply-side shock and risk-premium event for global crude and products, even before operational confirmation from Western sources.

## Detail

1) What happened: In the context of ongoing U.S. airstrikes on Iranian coastal and military targets around Bandar Abbas and South Pars, Iran’s Khatam al‑Anbiya Central HQ has formally declared the Strait of Hormuz closed to all vessels, including oil tankers and commercial ships (reports 1, 4, 28, 66, 104). The IRGC Navy has issued a statement that two ‘violating’ ships attempting to transit have been struck (reports 2, 3, 25, 64, 8). Multiple outlets are repeating this, though details on the vessels (flag, cargo, damage) remain unclear and largely from Iranian or secondary social sources. There are also unconfirmed and partially walked‑back claims of damage to a U.S. warship, but at least some of that has been flagged as likely false (reports 12, 13, 39, 108).

2) Supply/demand impact: Roughly 17–20 mb/d of crude and condensate plus several mb/d of refined products and most Qatari LNG exports normally transit Hormuz. Even if physical flows are not yet fully halted, an explicit Iranian order to close the strait combined with a demonstrated willingness to fire on ‘violating’ ships is enough to significantly disrupt insurance, routing decisions, and shipowner willingness to load in the Gulf. A credible, even temporary, closure or high‑risk environment could effectively remove a large portion of Gulf export capacity from the spot market. Immediate price impacts of >5–10% in Brent and Dubai benchmarks are plausible, with time spreads and freight rates spiking as traders price in potential prolonged disruption and re‑routing.

3) Affected assets and direction: Primary impact is sharply bullish for Brent, WTI, Oman/Dubai, and Gulf crude grades; bullish for refined products (gasoil, gasoline, jet) and LNG spot prices (TTF, JKM) via Qatar risk. Tanker equities and Middle East freight (VLCC, LR2) should see volatility with sharply higher risk premia. Safe‑haven flows are likely into gold and the U.S. dollar versus EM FX, while regional currencies (IRR, GCC pegs via CDS spreads), and regional equity indices could come under pressure. European gas hub prices gain on incremental LNG risk even if pipeline supply is unchanged.

4) Historical precedent: The closest analogues are the 1980s ‘Tanker War’ in the Gulf and periodic 2019–2020 tanker attacks and drone strikes on Saudi infrastructure, all of which added meaningful but more localized risk premia. A formal declaration of closure of Hormuz by Iran is unprecedented in recent decades and therefore carries higher tail‑risk weight.

5) Duration: Market impact will persist as long as (a) Iran maintains the closure declaration and (b) credible reports of live fire against commercial shipping continue. Even if some traffic continues under U.S. naval escort, risk premia in crude and LNG are likely to remain structurally elevated for weeks to months until there is a clear de‑escalation or negotiated maritime security framework.
