**Summary**: Iran’s IRGC Navy broadcast on VHF that Strait of Hormuz passage is only allowed with its permission and on designated routes, threatening interdiction of non‑compliant vessels. This directly challenges Oman’s newly declared toll‑free corridor under UNCLOS, re‑elevating tail‑risk of shipping disruption and restoring an oil risk premium despite some traffic resumption.

## Detail

1) What happened:
On Channel 16 VHF, the IRGC Navy issued a broadcast declaring that all vessels in the Persian Gulf and Sea of Oman must obtain IRGC permission and use designated routes to transit the Strait of Hormuz, warning that ships attempting passage without such permission will be dealt with. This comes just as Oman publicly reaffirmed it will keep Hormuz open under UNCLOS and levy no transit fees, and after reports that some tankers have begun using Omani routes without Iranian coordination. There are also conflicting signals about ships turning back and avoiding the Omani corridor after Iranian warnings.

2) Supply/demand impact:
No large‑scale physical disruption is confirmed in this specific update, but the risk of interdictions, detentions, or harassment has materially increased. About 17–20 million bpd of crude and condensate, plus significant LNG volumes from Qatar, transit Hormuz. Even a low‑probability, high‑impact threat can move prices several percent, as seen historically when Iran has seized or harassed tankers. The immediate effect is on risk premia rather than actual supply, but insurers, charterers, and shipowners may impose higher war risk premiums, reroute, or delay sailings, tightening prompt availability and time spreads.

3) Affected assets and direction:
Bullish for Brent and Dubai benchmarks, front‑end time spreads, and Middle East sour grades. VLCC and LNG carrier war‑risk insurance premia and freight rates through the Gulf are likely to rise. Qatari LNG and Saudi/UAE crude export differentials versus non‑Hormuz suppliers (e.g., US Gulf, West Africa, North Sea) may widen. Safe‑haven assets like gold could see incremental support if the situation escalates.

4) Historical precedent:
Past IRGC seizures (e.g., 2019 UK‑flagged tanker incidents) and threats against Hormuz have triggered 2–5% intraday moves in crude benchmarks with limited actual flow disruption, mainly via sentiment and insurance/freight repricing.

5) Duration:
Unless backed by actual interdictions, price impact may partially mean‑revert within days; however, as long as Iran maintains this declared posture and radio warnings, a structural risk premium will persist in Gulf‑linked energy, especially given parallel Iran–US tensions over the ongoing war and sanctions.
