**Summary**: Iranian state media report a formal prohibition on passage of U.S. and Israeli vessels through the Strait of Hormuz. While flows of third‑country cargoes are not explicitly blocked, the move sharply raises legal and operational risk around a chokepoint that handles ~20% of seaborne crude and key LNG flows. Expect a higher Middle East risk premium across oil benchmarks and freight, with options volatility bid.

## Detail

1) What happened:
Fars News reports that Iran has enacted a prohibition on passage of U.S. and Israeli vessels through the Strait of Hormuz under a new deal. This appears to move beyond rhetorical threats toward a declared legal/administrative restriction on specific flags/ownership, in a waterway through which roughly 17–20 million b/d of crude and condensate and sizable Qatari LNG volumes transit.

Importantly, the report does not state that Iran is closing Hormuz to all traffic, but rather targeting U.S. and Israeli ships. However, any selective ban heightens the probability of miscalculation at sea, more aggressive boarding/inspection practices, and possible shadow re‑flagging workarounds.

2) Supply/demand impact:
There is no confirmed disruption yet to physical flows, so this is currently a risk‑premium event rather than realized supply loss. However, U.S.-linked tankers and those with any perceived connection to Israel will reassess routing, insurance, and operational risk. Even a 1–2% notional threat to Gulf export capacity can justify several dollars per barrel of risk premium, as seen historically when Iran threatened closures or seized tankers.

3) Affected assets and direction:
• Crude benchmarks (Brent, WTI, Dubai) – bullish via higher geopolitical risk premium and steeper front‑end time spreads.
• Qatar-linked LNG benchmarks (TTF, JKM) – modest upside risk if shippers/insurers price in higher war‑risk premia for transiting Hormuz.
• Tanker equities and Persian Gulf/Middle East war‑risk insurance – higher rates and premia likely.
• Regional FX (IRR unofficial, GCC FX via equity sentiment) and EM credit spreads could see modest widening on headline risk.

4) Historical precedent:
Events in 2011–2012 (Iranian threats to close Hormuz) and the 2019 tanker attacks/seizures drove 3–8% short‑term moves in Brent and sharply higher implied volatility, despite limited sustained physical disruption. Markets tend to price worst‑case scenarios quickly, then fade if shipping flows remain normal.

5) Duration of impact:
If the ban remains declaratory and shipping data show uninterrupted flows by non‑U.S./non‑Israeli vessels, the price impact may be front‑loaded and partly mean‑reverted over days to a few weeks. Any follow‑on incident (seizure, near‑miss, or clash with U.S. naval escorts) would extend and amplify the risk premium, turning this into a medium‑term structural concern for Gulf exports.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Dubai Crude, Qatar LNG exports, JKM LNG, TTF gas, Tanker equities, Middle East CDS baskets, USD/IRR (offshore), GCC equity indices
