Stocks sink, oil prices rise after President Trump’s Iran war speech

President Trump's speech addressing the Iran war triggered a sharp market decline Thursday morning, with the Dow falling roughly 600 points (1.3 percent) and the S&P 500 dropping the same percentage at the opening bell. Oil prices surged simultaneously, a typical market reaction to geopolitical tension in the Middle East, where supply disruptions are a key concern. The dual movement—equities down, energy up—reflects investor anxiety about the economic fallout from potential escalation in the Iran conflict. Stock market volatility tied to military or diplomatic developments often moderates as investors assess actual policy impacts versus initial uncertainty. The markets' response signals traders are pricing in both the direct costs of conflict and broader economic headwinds.
