**Summary**: Shipping data show commodity ship transits through the Strait of Hormuz have fallen to the lowest level since May following reciprocal U.S. and Iranian strikes on vessels. The disruption is adding risk premium to crude benchmarks and heightening fears of a longer‑lasting supply constraint from the Gulf.

## Detail

1) What happened:
New shipping data indicate that only about 10 commodity vessels per day have transited the Strait of Hormuz over the past 10 days, the weakest throughput since May. This follows tit‑for‑tat U.S. and Iranian strikes on tankers in and around Hormuz, which have already driven an extension of gains in crude prices as reported in contemporaneous market coverage. While the waterway remains open, both physical operators and insurers appear to be scaling back exposure and/or rerouting flows.

2) Supply impact:
Roughly 20–21 mb/d of crude and condensate and significant volumes of refined products and LNG normally pass through Hormuz. A reduction in daily commodity ship transits to the lowest level in several months implies a meaningful but still partial curtailment of loadings and sailings. Even a 5–10% effective reduction or delay in flows—whether from deferred liftings, floating storage buildup, or longer routing—can tighten prompt physical balances and futures time spreads. The real constraint today is more about logistics and risk cost than barrels permanently offline, but it still functions as a supply‑side shock in the short term.

3) Affected assets and direction:
Crude benchmarks (Brent, WTI, Oman/Dubai) should maintain an upside bias with a fatter near‑term risk premium. Front‑month Brent could see moves well beyond 1% intraday as traders price in the chance of further escalation—particularly if more attacks occur or insurers widen war‑risk premiums sharply. Middle distillates (gasoil, jet, diesel) and fuel oil in Europe and Asia may also firm on potential delays from key Gulf exporters. Tanker equities and freight indices (especially VLCC/MR rates out of AG) are likely to benefit from higher risk premia and possible tonne‑mile extensions from rerouting.

4) Historical precedent:
Episodes such as the 2019–2020 tanker attacks around Hormuz and the 2011 Strait‑of‑Hormuz closure threats by Iran triggered multi‑dollar risk premia in Brent despite limited actual flow disruption. Current conditions are directionally similar: partial disruption plus elevated geopolitical uncertainty.

5) Duration:
The immediate price impact is likely to persist as long as military activity around commercial vessels continues and transits remain depressed. If no additional attacks occur and traffic normalizes, the risk premium could fade over days to a few weeks. Escalation into direct threats to close the strait or damage to key export terminals would shift this from a transient to a potentially structural multi‑month supply risk.
