U.S. stock markets opened lower this week as geopolitical tensions, particularly surrounding Iran, continue to exacerbate concerns over rising oil prices and climbing Treasury yields. Key indexes, including the Dow, S&P 500, and Nasdaq, all posted losses as investors reacted to heightened volatility. The situation worsened following Trump’s rejection of a potential peace proposal from Iran, leading to a surge in crude oil prices that surpassed $100 per barrel. The bond market also faced significant selling pressure, with Treasury yields hitting 19-year highs, raising fears of inflation and further rate hikes. The combination of these factors led to a broad decline in equity markets, with technology stocks particularly hard-hit. As the week progresses, analysts remain cautious amid ongoing uncertainty in the Middle East and its potential implications for global markets.
