Stock Market Today: Dow ends lower but still logs fifth month of gains; Nasdaq and S&P 500 gain in August despite Brent oil above $90 and 30-year yields at 5.25%

The attacks prompted a rise in oil prices, with Brent crude surpassing $90 per barrel. This increase in oil prices, coupled with geopolitical tensions, contributed to the Dow's decline. The Nasdaq and S&P 500, however, managed to gain in August despite these factors. The renewed U.S.-Iran strikes have reignited concerns about supply disruptions in the Middle East.

According to coverage from Reuters and BBC News, the fighting has put the possibility of $100 oil back in focus. The U.S. renewed strikes on Iran, which has led to increased volatility in the oil market. The impact of the U.S.-Iran strikes on global oil supplies is still unclear. The extent of supply disruptions in the Hormuz Strait remains uncertain.

The long-term effects on the stock market and oil prices are also not yet specified. The market's reaction to the geopolitical tensions and the potential for further escalation will be crucial in determining future trends.
