U.S. equity futures fell Tuesday after the Labor Day weekend, with Dow contracts down 0.8% and S&P 500 futures off 0.3%, while Nasdaq 100 futures were little changed. Brent crude rose 1.4% toward $99 a barrel, its highest level in six weeks, as Iranian threats of a maritime exclusion zone in the Persian Gulf and strikes by Iran-backed Houthi groups in Saudi Arabia heightened concerns over energy infrastructure. Strong August employment data revived expectations that the Federal Reserve could maintain restrictive policy or raise interest rates again if inflation remains above its 2% target. Investors are awaiting Friday’s Consumer Price Index report and Oracle’s quarterly results, while rising Treasury yields and the U.S. national debt exceeding $40 trillion add to market pressure.
