Recent escalations in U.S.-Iran tensions have led to a significant increase in oil prices, with Brent crude surpassing $90 per barrel after U.S. strikes on Iranian sites in the Strait of Hormuz. Stock markets reacted negatively, with major indexes like the Dow and Nasdaq experiencing declines as concerns over rising oil prices and potential inflation impact investor sentiment. Analysts note that this volatility is compounded by hawkish bets on interest rate hikes from the Federal Reserve. As geopolitical tensions persist, market experts warn of further fluctuations in both oil and equities in the coming days.
