The dominant narrative is a sharp de-escalation in US-Iran tensions, with the US pausing strikes and Trump expressing optimism about talks. This has triggered a massive oil price plunge (WTI -7.5%, Brent -8.7%), which is the primary market-moving event. The oil crash is bullish for consumer staples, airlines, and transports, but bearish for energy stocks. Simultaneously, the AI capex narrative is under severe pressure: Nvidia is down ~5% on reports of $750B+ in deal talks with OpenAI, raising concerns about circular financing and credit risk. This has dragged down the entire semiconductor sector (AMD, Teradyne, MU) and the Nasdaq. Apple has overtaken Nvidia as the world's most valuable company, a MAG7 carve-out that contradicts the broader tech selloff. The Fed decision looms Wednesday, with Trump publicly urging a rate cut, but the Fed is split. Citadel Securities anticipates an unexpected rate hike. Johnson & Johnson's $5.5B talc settlement is a notable corporate development. The Houthi drone strike on Saudi Aramco's Abqaiq facility is a counter-signal to the oil price drop, but the market is currently focused on the ceasefire. The narrative arc is a rapid de-escalation in the Iran conflict, but with a countervailing escalation in AI capex risk.
