The diplomatic standoff between the United States and Iran has intensified following reports that the Trump administration formally rejected a written 14-point peace proposal from Tehran. The Iranian plan reportedly suggested a two-stage de-escalation starting with a comprehensive ceasefire, followed by nuclear negotiations. However, U.S. officials have maintained that nuclear discussions cannot be tethered to broader regional hostilities, reinforcing a hardline stance that maintains the current stalemate. On the ground, no new military strikes or proxy attacks were confirmed in the last 24 hours. Despite the lack of fresh kinetic escalation, analysts and Iranian state media have begun characterizing the 40-day-old conflict as a 'war of attrition.' This shift in narrative suggests that the initial campaign has failed to produce a quick decisive outcome, potentially creating political challenges for President Trump as the domestic and economic costs of the confrontation become more apparent. Global energy markets continue to reflect the uncertainty of the situation. While oil prices showed slight easing on rumors of diplomatic movement, the persistent threat to the Strait of Hormuz keeps risk premiums elevated. Meanwhile, international involvement remains a factor, as evidenced by recent high-level discussions between President Trump and Chinese President Xi Jinping regarding regional stability, though no specific breakthrough on the Iran file has been announced.
