Wall Street experienced a sharp downturn as escalating military actions between the U.S. and Iran revived fears of oil supply disruptions. The Dow Jones Industrial Average dropped approximately 577 points on Wednesday, marking its steepest decline since May, as global oil prices surged.

Analysts at Societe Generale characterized the mood as "Here we go again," reflecting renewed anxiety over the Middle East conflict's impact on energy markets. Investors had recently grown optimistic, anticipating that falling oil prices would ease inflation and support economic growth in the latter half of the year. This optimism is now challenged by the renewed fighting.

The conflict threatens to reverse the recent trend of increased tanker traffic through the Strait of Hormuz, potentially leading to significant oil supply constraints. This uncertainty complicates the Federal Reserve's efforts to manage inflation and adds volatility to markets already sensitive to geopolitical events. The rapid nature of the U.S. and Iran's strikes, coupled with President Trump's statements, left investors scrambling to assess the fallout in real-time.
