US stock futures fall as oil prices revive inflation concerns

US stock futures fell Monday as rising oil prices revived inflation concerns and pushed Treasury yields higher, with technology shares facing the most pressure before the market open. Nasdaq 100 futures dropped about 1%, while S&P 500 futures fell roughly 0.5% and Dow futures slipped 305 points. Brent crude approached $108 per barrel after President Donald Trump rejected Iran's proposal to reopen the Strait of Hormuz, though further talks are expected this week. Investors are awaiting US inflation and employment data that could determine whether the Federal Reserve follows September's rate hike with another increase in October. Markets priced about a 66% probability of an October hike, while the 10-year Treasury yield held near 5.2%.
