NewsletterStock market wrap upstock market👁 9 viewsSeptember 23, 2026
Market Reaction & Rate Outlook:
- Markets & Oil: US stocks and bonds fell as rising oil prices (Brent crude settled up 3.86% at $103.08/bbl, WTI up 1.81% to $92.16/bbl) renewed inflation fears. Stronger US business activity data and a weak $70B Treasury auction pushed yields to near two-decade highs.
- Federal Reserve Policy: Following a 25bps rate hike, Fed Governor Barr indicated further tightening will likely be needed. Money markets are fully pricing in two additional rate increases over the next three policy decisions.
Geopolitics & Defense:
- F-35 Stealth Jet Parts Diverted: The Chinese government took possession of sensitive F-35 stealth aircraft parts (a cockpit canopy and weapons-bay door) that were diverted to Hong Kong via UPS while in transit from Australia to the US for maintenance. The Pentagon confirmed efforts to retrieve the components.
- Strait of Hormuz: Iranian President Pezeshkian stated Iran will not permit freedom of navigation through the Strait of Hormuz while sanctions and a US blockade remain.

- Iraq–Turkey Agreement: The Iraqi PM and Turkish President agreed on a gradual handover of camps in northern Iraq from Turkish forces to the Iraqi federal government.
- Diplomacy: Russian Presidential Envoy Dmitriev traveled to the US for talks with members of the Trump administration.
Energy & Diesel Export Rumors:
- Reports that the US is considering a diesel export ban were dismissed as "fake news" by the White House. Energy Secretary Chris Wright noted the administration is instead working with refiners to voluntarily limit diesel exports.
AI & Technology Industry:
- AI Risks & Safety: Anthropic's Dario Amodei warned that AI poses potential risks to humanity as a whole and noted the company will slow development as needed for safety. AI scientist Yoshua Bengio called AI risks "real and imminent."
