Dow Jones| Nasdaq | S&P 500 | US Stock Market Today | Live: US stock futures decline as US-Iran escalation rattles sentiment

US stock futures declined at the start of the week as escalating US-Iran tensions in the Gulf lifted crude oil prices by more than 3% and dragged chip stocks, with Micron, SK Hynix, Western Digital, Seagate and Sandisk posting sharp losses. Nasdaq futures led the declines, while investors await key US economic data including CPI, PPI and retail sales, alongside second-quarter earnings from major banks such as JPMorgan, Goldman Sachs and Morgan Stanley. US President Trump's comments about potentially taking control of the Strait of Hormuz as a 'guardian' further unsettled markets, raising concerns over global energy supply disruptions and inflation risks.
