U.S. stock indices, including the Dow Jones, S&P 500, and Nasdaq, have experienced significant declines, with the Dow falling over 400 points as new U.S. strikes against Iran raised concerns in the markets. The surge in oil prices, now exceeding $90 amid fears of inflation, alongside rising bond yields, has further pressured the stocks. The yield on the 10-year Treasury has reached its highest level since early 2025, compounding market jitters. Observers note that September traditionally marks a challenging month for equity markets, and current geopolitical tensions have heightened the overall uncertainty.
