**Summary**: Ship-tracking data show only four commodity carriers transiting the Strait of Hormuz versus a 10-day average of about 13, confirming a sharp and persistent slump in flows. This materially elevates near-term supply risk and risk premia for crude and products linked to Gulf exports, reinforcing upside pressure on prices and freight.

## Detail

1) What happened: Fresh Kpler data report that only four commodity-carrying vessels transited the Strait of Hormuz today compared with a 10‑day average of around 13. This confirms that the sharp slowdown in Hormuz traffic is not a one-off but an ongoing disruption amid recent reports of tanker mining incidents and Iranian drone activity near U.S. 5th Fleet assets in Bahrain.

2) Supply/demand impact: Roughly 17–20 mb/d of crude and condensate and several mb/d of products normally pass through Hormuz. A decline from ~13 to 4 commodity carriers per day, if representative of crude and products, implies an immediate throughput reduction on the order of 60–70% versus recent norms, even if some cargoes are delayed rather than canceled. In practice, charterers can reschedule and reroute, but insurers and shipowners will demand sharply higher war-risk premia, and some vessels may avoid the area altogether while risk is reassessed. Even temporary slow steaming, convoying, or inspection delays effectively remove some supply from the prompt market by lengthening transit times and tying up tonnage.

3) Affected assets and direction: The primary impact is bullish for Brent and Dubai benchmarks, and for Middle East–Asia physical crude differentials (e.g., Murban, Arab Light, Qatar Marine). European and Asian gasoil and jet cracks are also likely to widen on fears of delayed product flows. Freight rates for VLCCs and LR tankers on AG‑East/West routes should firm significantly, and war-risk premia for hull and cargo insurance in the Gulf are likely to spike. Risk aversion and geopolitical hedging should also be mildly supportive for gold. The disruption is less directly relevant for U.S. WTI but positive via global arb.

4) Historical precedent: Episodes such as the 2019 tanker attacks near Fujairah and the 1980s Tanker War saw relatively modest physical damage but outsized impacts on price volatility and insurance/freight costs. Market behavior then suggests even perceived vulnerability of Hormuz can add several dollars per barrel in risk premium.

5) Duration: The immediate flow hit may be measured in days, but the elevated risk premium could persist for weeks or longer depending on whether additional attacks occur and whether naval escorts or diplomatic de‑escalation are put in place. If traffic normalizes quickly, some price impact will unwind, but higher structural insurance and routing costs are likely to remain baked into forward curves for some time.
