**Summary**: Iran’s IRGC Navy publicly states it is ‘directing’ traffic in the Strait of Hormuz and will stop non‑compliant ships, while fresh imagery shows a large vessel on fire at the strait’s entrance with IRGC fast boats nearby. This signals an operationalized quasi‑blockade risk, adding to existing U.S.–Iran strikes and prior tanker seizure, and should widen energy risk premia, especially in crude and Middle East freight.

## Detail

1) What happened:
New IRGC statements (reports [3], [41]) say the IRGC Navy is now actively ‘guiding’ transiting vessels in the Strait of Hormuz and will stop ships that ignore warnings. The IRGC released footage of round‑the‑clock fast‑boat patrols. Separately, satellite imagery from 29 May (report [42]) shows a 252‑meter vessel on fire at the entrance to the Strait of Hormuz with four suspected IRGC large speedboats approaching and a fifth departing. This comes on top of U.S. strikes on Iranian targets near the strait and previously reported seizures/boardings, indicating a pattern of Iran asserting de‑facto control over chokepoint shipping.

2) Supply/demand impact:
Roughly 17–18 million b/d of crude and condensate and a significant share of global LNG exports transit Hormuz. There is no confirmed full closure yet, and no explicit disruption to named export terminals or pipelines, but guidance-plus-enforcement by the IRGC materially raises the probability of:
- Individual tankers or LNG carriers being detained, delayed, or harassed.
- Higher war‑risk insurance premia and freight rates for AG–Asia and AG–Europe routes.
Even a 5–10% reduction in loadings or effective transit capacity over a short period (through delays and rerouting) would be enough to move Brent several dollars; at minimum, options markets are likely to price higher implied volatility.

3) Affected commodities/assets and direction:
- Brent, WTI, Oman/Dubai: Bullish via higher risk premium; front‑end spreads likely to tighten.
- Asian LNG spot (JKM), European TTF: Bullish on heightened supply disruption risk from Qatari and other Gulf exports.
- Tanker equities and AG‑linked freight indices: Bullish on higher earnings from war‑risk and rerouting, though operational risk rises.
- Gold and USD safe havens (JPY, CHF): Mildly bullish on geopolitical risk.

4) Historical precedent:
Episodes in 2019 (tanker attacks and seizures near Hormuz) and the 1980s ‘Tanker War’ show that even limited incidents can add several dollars to crude via risk premium and spike Gulf freight and insurance costs. The current situation is similar but layered onto an existing kinetic U.S.–Iran exchange.

5) Duration:
If no further ships are actually seized or damaged, the price impact may fade over days to a couple of weeks but leave a modest structural risk premium. Escalation to repeated interdictions or clear pattern of attacks would shift this from transient to more structural and could sustain a larger move (>5–10%) in crude and LNG benchmarks.
