**Summary**: Iranian state TV reiterates that Tehran controls Strait of Hormuz shipping, with all vessels awaiting naval permission, alongside a newly announced formal permit regime. This raises the risk of delays, de facto selective blockades and insurance repricing for Gulf crude and products. Near term, this supports higher Brent/Dubai benchmarks and tanker freight, while increasing regional war-risk premium.

## Detail

1) What happened: Iranian state media has again claimed that Iran controls shipping through the Strait of Hormuz, stating that all vessels are awaiting naval permission to transit. In parallel, Tehran has rolled out a new formal permit system for vessels using the strait. This comes as the UAE is reported to be quietly moving some crude exports through Hormuz with AIS turned off to avoid potential Iranian targeting. While there is no confirmed kinetic closure, Iran is asserting regulatory and operational control over a chokepoint that handles ~17–20% of global oil supply and a large share of LNG exports from Qatar.

2) Supply/demand impact: There is no physical loss of barrels yet, but the risk of disruption is sharply higher. Even modest slowdowns, inspections, or selective denial of passage could effectively tighten prompt supplies by delaying 0.5–1.0 mb/d of flows at times, especially for UAE, Saudi and Qatari cargoes. Insurance premia and war-risk surcharges for tankers and LNG carriers are likely to rise, pushing up delivered costs to Asia and Europe. If traders and shipowners preemptively reroute or reduce liftings, the perceived availability of Gulf crude in the prompt market tightens, supporting backwardation and spot benchmarks.

3) Affected assets and bias: Brent, Dubai, and Oman crude benchmarks are biased higher, with potential >1–3% intraday upside as the market prices in heightened transit risk. LNG spot prices in Asia (JKM) gain upward pressure on concerns about Qatari exports, though structural hedging may mute the move initially. Tanker equities (particularly VLCC and LNG carrier owners) and Gulf shipping indices could rally on higher freight and risk premia. Gulf sovereign CDS spreads and local FX (e.g., AED forwards) may see modest widening on geopolitical risk.

4) Historical precedent: Past episodes where Iran signaled control or threatened closure of Hormuz (e.g., 2011–2012, 2019 tanker attacks) produced several‑percent spikes in Brent and persistently elevated war-risk insurance. Even without full closure, legal/permit controls can be leveraged to harass or delay specific flags or counterparties, creating a quasi‑sanctions effect.

5) Duration: The impact is primarily risk‑premium driven but could become semi‑structural if Iran maintains and enforces this permit regime as a tool of geopolitical leverage. Expect immediate price sensitivity to any reports of delays, boardings, or denied transit, with an enduring higher geopolitical premium baked into Gulf energy exports as long as tensions with the US/Israel and the UAE remain elevated.
