US-Iran diplomacy following the 2026 conflict and June memorandum of understanding continues to shape trader views on direct contact between President Trump and Supreme Leader Mojtaba Khamenei. Trump publicly signaled openness to a meeting in early June if it advanced ceasefire implementation, nuclear limits, or Strait of Hormuz reopening, yet Iranian officials and Khamenei advisers have repeatedly ruled out personal engagement. Khamenei endorsed the interim framework while stressing resistance to excessive US demands and maintaining distance from public appearances amid persistent questions over his health and location. Ongoing negotiations remain channeled through intermediaries and lower-level channels, with no confirmed direct verbal or in-person interaction reported through mid-September. Market pricing reflects these structural barriers alongside the possibility that progress on sanctions relief or regional de-escalation could alter incentives before year-end resolution.
