Question

How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BZ=F | The sustained US blockade alongside Iranian attacks keeps a material share of Gulf crude trapped, underpinning a durable risk premium in Brent despite short-term price dips on sanctions event risk. | Up1-3m | Analyses note that Hormuz traffic has been choked off since the start of the war, with hundreds of tankers trapped and Brent having risen nearly 30% since then, peaking near $115, supported by ongoing blockade operations. |
| TD3C | Blockade activity and disrupted flows force charterers to pay elevated freight and war-risk premia, pushing up VLCC rates on Hormuz-linked routes. | Up1-3m | Reports cite VLCC freight from the Middle East to China peaking at W419, about $423,000 per day, and emphasize that commercial traffic through Hormuz remains heavily disrupted by the US blockade and Iranian actions. |
| USO | Physical constraints through Hormuz and sustained conflict-driven volatility support higher long-dated crude prices and volatility exposure tracked by USO. | Up1-3m | Oil benchmarks have traded in wide ranges, with Brent between roughly $80 and $100 over the past month and nearly 30% above pre-war levels, attributed to shipping disruptions and blockade-linked supply risks. |
