Question
President Trump rules out extension of US–Iran ceasefire and says United States has no talks planned with Iran as naval blockade continues

How this development reaches the affected companies
| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| BZ=F | The end of the ceasefire without new talks increases perceived likelihood of further military incidents affecting Gulf oil exports, sustaining a geopolitical premium in Brent. | Up1-5d | Oil prices settled at their highest level in more than three weeks, with Brent around $91.02 per barrel, after Iran shifted to a more offensive posture and the US ruled out extending the ceasefire. |
| ITA | Extended US‑Iran conflict and ongoing naval operations boost expectations for defense spending and demand for aerospace and defense equipment. | Up1-3m | Analytical commentary tied escalating Middle East tensions and threats of action, including Trump’s statements about Iran and Oman, to stronger performance in defense‑related equities. |
| DXY | Heightened geopolitical risk and higher oil‑driven inflation concerns support safe‑haven flows into the US dollar. | Up1-5d | Gold dipped as oil‑fueled inflation risks and US‑Iran tensions bolstered the USD, with analysts noting Trump’s hard line and the lapse of the MoU as factors. |
