U.S. stock markets have experienced periods of recovery and renewed volatility driven by geopolitical tensions, inflation concerns, and central bank policy. Following a three-day losing streak, Wall Street indices saw a brief recovery as the Dow Jones rose 0.22%, the Nasdaq increased 0.16%, and the S&P 500 climbed 0.21%. This movement was supported by the release of Federal Reserve meeting minutes and Treasury Department plans to increase the duration of government bond buybacks. However, market pressure has since intensified due to rising inflation concerns and direct military exchanges between the United States and Iran, including strikes on Iran’s Larak Island. In the first trading session of September, Wall Street faced further downward pressure as the Dow Jones fell 0.79%, the S&P 500 dropped 0.71%, and the Nasdaq declined 1.03%. This decline was driven by a surge in oil prices, with Brent crude rising toward $95 per barrel following U.S. strikes against targets in Iran, raising fears of disruptions in the Strait of Hormuz. As of September 2, markets showed signs of stabilization. The Dow Jones rose approximately 0.7% and the S&P 500 increased by 0.4% as oil prices saw a moderate decline. On Wednesday, stocks rose further, with the Dow climbing 0.5%, the S&P 500 increasing 0.6%, and the Nasdaq rising 0.5%. Despite the six-month conflict between the U.S. and Iran resulting in the shutdown of the Strait of Hormuz, Brent crude remained relatively stable, rising 1% to $95.69 per barrel. Volatility has since expanded globally as renewed U.S. military strikes on Iran pushed Brent crude toward a five-week high exceeding $95 per barrel. Simultaneously, a global bond sell-off has pushed the U.S. 10-year Treasury yield toward the 5% threshold, a level analysts suggest “could trigger equity market corrections.” On September 11, Wall Street indices ended a four-day losing streak.
