Multiple high-signal developments have emerged in this window. First, Iranian President Pezeshkian has reportedly submitted a resignation letter to the Supreme Leader's office, per Iran International and corroborated by multiple sources. This represents a major escalation in Iran's internal political crisis, coming alongside an IRGC member assassination in Tehran—the first targeted killing since the April ceasefire. These events significantly reduce the probability of a US-Iran permanent peace deal and threaten the Strait of Hormuz reopening, which had been a key counter-signal to the oil supply crisis. Second, the US and Iran traded messages over the weekend seeking changes to a draft ceasefire extension and Hormuz reopening agreement, but progress is unclear, per Seeking Alpha. Third, Russian refinery strikes have knocked out ~25% of diesel and ~30% of gasoline capacity, pushing Russia toward export bans on both fuels—this adds to global fuel supply tightness. Fourth, the US is tightening AI chip export rules for Chinese firms overseas, per Seeking Alpha, which directly impacts NVDA and other chip stocks. Fifth, Berkshire Hathaway's $6.8B all-cash acquisition of Taylor Morrison Home Corp. is confirmed by Bloomberg, a carry-forward from prior awareness. The Iran war narrative is ESCALATING on the political front, while the oil supply disruption theme intensifies with Russian refinery damage. Markets have been shrugging off the Iran war amid AI frenzy and ceasefire hopes, but the Pezeshkian resignation and IRGC assassination are new negative catalysts that could reverse that risk-on sentiment.
