U.S. stock index futures trended lower on October 8, 2026, amid rising energy prices and concerns over potential military operations in Iran. Investors also digested new data showing increased one-year inflation expectations.
Why it matters
The market pullback reflects heightened uncertainty as traders balance geopolitical threats with persistent inflationary pressure and rising Treasury yields. This climate has complicated the outlook for equities and commodities.
One-year inflation expectations rose to 3.9%, while the 10-year Treasury yield reached 5.35% intraday. Brent crude increased 2.29% to $102.49 a barrel.
