US stock futures edged lower Monday after a surge in Treasury yields drove losses across major averages last week. The Dow fell 0.8% for a second straight weekly decline, while the S&P 500 and Nasdaq Composite dropped 1.4% and 2%, respectively, ending three-week winning streaks. The 30-year US Treasury yield rose above 5.3%, its highest level in nearly two decades, as yields in Japan, France and Germany also reached multi-year highs. Investors remain concerned that the prolonged US-Iran conflict could keep oil prices high and sustain inflation, reducing the scope for interest-rate cuts. Treasury Secretary Scott Bessent is expected to announce new sanctions on Iran, while markets await the July PCE inflation report, a key inflation gauge, and Federal Reserve Chair Kevin Warsh’s speech at the Jackson Hole symposium later this week. Nvidia and Marvell Technology earnings are also in focus.
