Stock Market Today: Dow Slides On Rising U.S.-Iran Tensions; Oil Prices Jumping Again (Live Coverage)

U.S. stock markets opened lower Monday as escalating geopolitical tensions between the U.S. and Iran triggered investor caution, with the Dow Jones Industrial Average leading declines. Oil prices surged amid fears of potential supply disruptions in the Middle East, adding pressure to energy-dependent sectors and contributing to broader market volatility. Boeing and Tesla earnings reports, scheduled for this week, remain in focus as investors weigh corporate performance against macroeconomic uncertainty and geopolitical risks. The Nasdaq and S&P 500 also faced downward pressure, reflecting broader risk aversion as traders prioritized safe-haven assets amid the unfolding crisis. Analysts warn prolonged tensions could further destabilize global markets, particularly if oil prices continue climbing or military escalation materializes.
