Brent crude has climbed back above $105–$107 after President Donald Trump rejected Iran's proposal to reopen the Strait of Hormuz, reviving inflation concerns and weighing particularly on growth/technology stocks. Yahoo Finance Today's economic calendar is light, with the Dallas Fed Manufacturing Index at 10:30 AM ET and Richmond Fed President Tom Barkin speaking at 1:30 PM; New York Fed President John Williams also begins a two-day regional visit. Hyperstocks Earnings after the close include Jefferies Financial Group and Vail Resorts, while investors are already positioning for Micron earnings Wednesday, PCE inflation, JOLTS/ADP employment data and Friday's jobs report. The key drivers today are oil/Iran headlines, the 5.2% Treasury yield and Fed rate expectations, with higher energy prices and yields presenting the biggest near-term threat to last week's tech-led momentum. 28-SEP-2026 06:56 AM ET
