2. Midday check12:31 PM ET

   U.S. equities are lower as the Nasdaq 100 opens down, putting its four‑session rally at risk. Bond yields are surging after hot economic readings pushed the 10‑year Treasury to a fresh 19‑year high, fuelling fears of additional Federal Reserve rate hikes. Meanwhile, a Trump‑Xi summit has put AI safety talks on the table while Iran’s UN speech blamed the United States and Israel for global instability, adding geopolitical tension. McDonald’s announced a major spend on restaurant upgrades and training, and Social Security checks are projected to be cut by $540 a month within six years.

   The S&P 500, Nasdaq 100 and Dow Jones were pressured as Treasury yields rose above 5%, with the Nasdaq ending sharply lower and the Dow down about 350 points. A CNBC piece warned of the economic impact of soaring yields, while AI buzz grew with Zuckerberg’s Meta briefing and OpenAI‑Anthropic CEOs at the U.N. Geopolitical focus turned to Trump’s meeting with Xi over Chinese auto exposure and oil firms warning that a diesel export ban could lift fuel prices. Investors now eye the U.S. PCE inflation report due September 30.
