**Summary**: Iran’s announced closure of the Strait of Hormuz following U.S. strikes, plus U.S. attacks on an Iranian-linked tanker and cargo dhow in the Gulf of Oman, sharply escalates supply-risk for Gulf crude and products. Prompt oil has already jumped over $2; further upside and volatility are likely as markets re‑price disruption odds and broader MENA conflict risk.

## Detail

Iran has publicly announced the closure of the Strait of Hormuz after U.S. military strikes, and this is being accompanied by kinetic activity at sea: U.S. forces reportedly attacked the tanker Settebello, killing Indian crew, and separately struck a 150‑ton Iranian cargo dhow in the Gulf of Oman. Jordan reports intercepting around 20 Iranian missiles and there are continued exchanges of fire between the U.S. and Iran, though CNN notes negotiations are still ongoing. Spot oil benchmarks are already reported up more than $2/bbl, indicating the market is rapidly pricing in elevated Gulf transit risk.

Roughly 17–20 million bpd of crude and condensate and significant LNG volumes transit Hormuz under normal conditions. Even if ‘closure’ is partial, short-lived, or more declaratory than enforced, the threat materially raises the probability of shipment delays, higher insurance premia, re‑routing, and self‑sanctioning by shipowners. A tangible, durable interdiction of flows through Hormuz of even 10–20% would constitute a multi‑million bpd supply shock—on par with or larger than typical OPEC+ cuts—and would rapidly tighten prompt crude and spot LNG balances. For now, the physical impact is uncertain, but the risk premium element alone is enough to move benchmarks several percent.

The immediate market reaction is bullish for Brent and Dubai/Oman benchmarks, with front spreads likely to widen as traders price higher nearby disruption risk. Time spreads in refined products (especially middle distillates in Europe and Asia) may also strengthen on fears of constrained Arab Gulf exports. LNG spot prices in Asia and Europe should find support on potential bottlenecks for Qatari exports through Hormuz, even if actual shipments are not yet blocked. Freight, war risk insurance premia, and regional equities/FX (GCC, INR given Indian fatalities, TRY via broader EM risk sentiment) are all exposed to downside risk.

Historically, episodes such as the 1980s ‘Tanker War’, the 2019–20 Gulf tanker attacks, and prior Iranian threats to close Hormuz have generated several‑dollar risk premia in crude without full-scale flow interruption. This event appears at least as acute in geopolitical terms, with live U.S.–Iran exchanges and documented strikes on commercial/para‑commercial vessels. Unless there is a swift de‑escalation or clear evidence that transits continue largely unhindered, the impact is likely to be more than a one‑day headline spike: elevated volatility and a structurally higher Gulf risk premium could persist for weeks, with the tail risk of a genuine physical outage keeping upside skew in energy markets.
