WS #8777

The dominant signal in this window is a sharp escalation in Iran-US tensions. Multiple sources report that Iran has shut down negotiations with the US and vowed to close the Strait of Hormuz indefinitely, while also striking a container ship (MSC Sariska) with an anti-ship missile in the Gulf of Oman. This represents a significant escalation from the previously stable narrative. Oil prices are surging—WTI +5.49%, Brent +5.02%—on the back of this uncertainty, with Bloomberg confirming oil holds its biggest gain in a month. The Iran deal optimism from earlier (Trump expecting a deal within a week) is now directly contradicted by Iran's walkout and military action. Separately, Alphabet's $80 billion AI capital raise with Berkshire Hathaway taking $10 billion is a major corporate finance story, signaling massive AI infrastructure spending. The Florida lawsuit against OpenAI alleging safety failures and child endangerment adds regulatory risk to the AI sector. Markets closed at all-time highs on AI enthusiasm and Iran talk optimism, but the post-close Iran escalation could reverse this.
