US stocks declined Monday as renewed US-Iran tensions heighten uncertainty and threatened peace talks. The Nasdaq Composite fell about 0.3%, the S&P 500 dropped 0.2%, and the Dow Jones Industrial Average edged down 0.1%. The escalation followed a US Navy seizure of an Iranian vessel, while Iran fired at ships and halted traffic in the Strait of Hormuz. Oil prices jumped, with WTI crude rising 5.2% above $86 and Brent gaining 5.1% past $95. Investors are watching upcoming earnings from Tesla, Intel, and United Airlines.
