US Inflation Cools Sharply in June, Lifting Rate-Cut Hopes as Oil Surges on Geopolitical Tensions
U.S. consumer prices rose at a slower-than-expected pace in June 2026, with the Consumer Price Index increasing 3.5% year-over-year, down from 4.2% in May and below consensus estimates of 3.8%. The data triggered immediate market reactions, including a weaker U.S. dollar and boosted expectations for Federal Reserve rate cuts later in 2026. Meanwhile, oil prices climbed to a one-month high amid renewed U.S.-Iran tensions at the Strait of Hormuz.
Equity futures advanced on the session, with Nasdaq futures leading gains at 1.50% and S&P 500 futures up 0.51%. The developments unfolded against a backdrop of mixed sector performance and notable corporate moves in technology.
