The recent military attacks by the United States and Israel on Iran have caused significant fluctuations in global markets as anticipated. Oil prices experienced a sharp increase following these events, with Brent crude rising by 6.4% to approximately $77.50 per barrel, momentarily exceeding $82. In the United States, crude oil also rose by 6.2%, reaching $71.17 per barrel. Additionally, gold prices saw a rise of about 2.4%, reaching close to $5,370 per ounce, indicating investor responses to market uncertainties.

Futures for the S&P 500 and Dow Jones indexes showed declines of approximately 0.7% before the market opened, while the tech-heavy Nasdaq index saw a slightly higher decline of 0.8%. These trends reflect the immediate market reactions to geopolitical events, as investors often adjust their portfolios in response to international conflicts that may disrupt supply chains and energy markets.

Asian stock markets also opened lower in reaction, with Japan's Nikkei 225 index initially dropping more than 2%. However, as trading progressed, the decline eased, stabilizing to a 1.2% drop shortly before 7 AM Finland time. The overall trend indicates a cautious market environment influenced by geopolitical tensions, prompting concerns over potential economic repercussions as investor sentiment shifts in response to the evolving situation in Iran.
