U.S. stock markets experienced a slight decline on Monday, with the S&P 500 dropping 0.2% to close at 7,109.14, the Dow Jones Industrial Average falling less than 0.1% to 49,442.56, and the Nasdaq Composite decreasing 0.3% to 24,404.39. This marked the end of the Nasdaq's impressive 13-day winning streak. The downturn was primarily attributed to escalating tensions between the U.S. and Iran, particularly after Iran's warning about the potential closure of the Strait of Hormuz, a critical oil shipping route. Additionally, the U.S. seized an Iranian cargo ship near Oman, further heightening investor concerns. In response to these geopolitical tensions, oil prices surged, with U.S. crude rising approximately 6.9% to $89.61 per barrel and Brent crude climbing 5.6% to exceed $95 per barrel. Despite these developments, market reactions remained relatively subdued, as many investors still hold out hope for a diplomatic resolution. Bank of America economist Claudio Irigoyen cautioned that the market may be underestimating the risks involved, suggesting that a quick resolution is unlikely. Looking ahead, major companies such as Tesla, Intel, and United Airlines are set to report earnings, which will be crucial for determining the future trajectory of the stock market.
