Biggest Stories at 4 PM CDT

  1. Oil has moved from crisis pricing toward diplomatic pricing. Brent fell approximately 5% to below $84 as Oman and Gulf governments pursued a mechanism for passage through Hormuz. The decline provides broad economic relief, but the Jizan refinery shutdown and continuing Red Sea attacks show that the regional energy system remains vulnerable.

  2. The AI boom is encountering a global financial stress test. Asian chip markets fell sharply, semiconductor competition from China intensified and Nvidia’s possible OpenAI guarantee raised questions about circular financing. Investors are no longer rewarding infrastructure commitments automatically; they want evidence of demand, manageable debt and durable returns.

  3. Washington’s diplomatic calendar widened beyond Iran. Trump and Zelenskiy discussed reviving talks with Russia and allowing Ukraine to manufacture Patriot interceptors before attending Senator Lindsey Graham’s funeral. The meeting connected military production, Ukrainian security and the possibility of a renewed negotiating channel.
