How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BZ=F | Lower Hormuz throughput reduces expected available global crude supply and supports Brent’s location-specific risk premium. | Up1-5d | Kpler-tracked clearance was 10,591 kilobarrels per day versus a 17,133-kilobarrel-per-day prewar baseline. |
| STNG | Restricted tanker passage increases demand for available product-tanker capacity and supports freight earnings. | Up1-4w | Shipping volumes through Hormuz remained far below prewar levels. |
| ZB=F | A sustained energy supply shock can lift inflation expectations and reduce the appeal of long-duration Treasury futures. | Down1-4w | Oil prices remained above $100 per barrel in the reported market response while Hormuz flows stayed constrained. |
| XAUUSD | Ongoing disruption at a major energy chokepoint increases geopolitical and inflation-hedging demand for gold. | Up1-5d | Iran continued restricting shipping and volumes remained below prewar levels. |
