US Stock Futures Fall as Middle East Tensions Escalate Over Strait of Hormuz

U.S. stock index futures dropped after President Donald Trump rejected an Iranian ceasefire proposal regarding the Strait of Hormuz, dampening global market sentiment. S&P 500 Futures fell 0.27% to 7,783.0 points, Dow Jones Futures slid 0.3% to 51,994.0 points, and Nasdaq 100 Futures declined 0.2%. Iran's proposal sought to reopen the shipping lane within seven days in exchange for lifting sanctions and releasing frozen assets, terms deemed unacceptable by the U.S. The escalating conflict sent Brent crude up nearly 2%, while an OpenAI training halt added further pressure to technology equities.
