How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BZ=F | Interdiction and redirection of commercial shipping increase the probability of constrained Gulf supply and higher transport risk. | Up1-5d | CENTCOM said 110 commercial vessels had been redirected while US forces enforced the blockade. |
| STNG | More vessel diversions and blockade enforcement can lift product-tanker utilization, freight rates and war-risk premia. | Up1-5d | US forces reportedly redirected commercial vessels in the Gulf under blockade enforcement. |
| ITA | A sustained naval blockade and heightened regional military posture support expectations for defense procurement and utilization. | Up1-4w | CENTCOM said the USS Rafael Peralta was enforcing the blockade in regional waters. |
| USO | A higher probability of disrupted Iranian and Gulf flows increases the near-term crude exposure of the oil fund. | Upintraday | The blockade directly affects commerce entering and leaving Iranian ports and coastal areas. |
