US-Iran tensions have escalated sharply following the death of Supreme Leader Ali Khamenei and Mojtaba Khamenei's succession amid reported US military strikes that degraded Iranian capabilities. President Trump has publicly described Mojtaba as severely weakened or "90% gone," while the new Iranian leader has issued statements accusing the US of breaching a memorandum of understanding and vowing forceful responses through proxies. Earlier remarks by Trump about potential meetings were dismissed by Iranian officials as unrealistic. These developments, combined with ongoing military and diplomatic friction rather than engagement channels, shape trader assessments of direct talks occurring by the market's resolution date. Any de-escalation signals, backchannel diplomacy, or shifts in bilateral posture before year-end could still alter probabilities.
