**Summary**: Iranian officials say a temporary arrangement with Oman will require ships to notify Tehran before exiting the Strait of Hormuz, effectively granting Iran operational oversight over key traffic. This formalizes Iran’s gatekeeping role amid ongoing tensions and prior attacks on vessels, supporting a higher risk premium in crude benchmarks and related freight.

## Detail

1) What happened:
New statements from Iranian officials and Reuters-sourced reporting indicate that Iran and Oman are negotiating, and now publicly describing, a ‘temporary plan’ under which Oman will allow ships to leave the Strait of Hormuz only after notifying Iran. A high‑level Iranian source says the plan would give Tehran “full control” over the movement of incoming ships, and another official now asserts Oman will require Iran notification for outbound traffic as well. This follows recent Iranian threats toward US warships and confirmed attacks on commercial shipping in the approaches to Hormuz.

2) Supply/demand impact:
Roughly 17–20 mb/d of crude and condensate and significant LNG volumes (Qatar) move through Hormuz. There is no confirmation of a closure, but regulatory and de‑facto control by Iran over both inbound and outbound traffic raises the probability of intermittent delays, selective harassment, or targeted seizures, especially of US‑, UK‑, or allied‑linked tonnage. Even low single‑digit percentage interruptions (e.g., 0.5–1.0 mb/d of temporarily delayed crude or refined products) would be enough to materially tighten prompt physical availability and prompt‑month spreads. Shipping insurers are likely to widen war‑risk premia further, and some owners may refuse fixtures into the area, raising effective transport costs.

3) Affected assets:
The immediate effect is a bullish risk premium for Brent and Dubai benchmarks, front‑end timespreads, and Middle East sour grades (Basrah, Arab Light). LNG freight and JKM/TTF could see upside if Qatari flows are perceived at risk, even absent actual disruption. Tanker equities and war‑risk insurance pricing likely gain; Persian Gulf crude differentials vs Atlantic Basin grades may widen.

4) Historical precedent:
Episodes such as the 2019 “tanker war” in the Gulf and prior IRGC detentions regularly added 2–5% to oil prices on headline risk alone, without full closures. Here, the novelty is an overt, quasi‑legalized Iranian gatekeeping arrangement via Oman, which increases the structural nature of the risk.

5) Duration:
The impact is medium‑term structural rather than a one‑day shock. As long as this framework exists and the US–Iran file remains unsettled, markets will likely price a persistent geopolitical premium, with episodic spikes on each new incident.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Dubai Crude, Qatar LNG-linked benchmarks, JKM LNG, TTF Gas, Tanker equities, Middle East crude differentials
