U.S. stock markets closed lower on August 5, 2025, with the S&P 500 declining 0.35%, the Nasdaq falling 0.28%, and the Dow dropping 0.39%. The losses followed weaker-than-expected ISM services sector data, which indicated a slowdown in economic activity. Market volatility increased, reflected by a rise in the VIX index. Additionally, renewed tariff threats from President Donald Trump contributed to the negative sentiment. Despite early gains, all three major indices reversed course and ended the trading session in negative territory. Meanwhile, the Mexican Stock Exchange's IPC and FTSE Biva indices advanced, with Industrias Peñoles noted as a top performer. The U.S. dollar remained flat amid the mixed economic signals and geopolitical tensions involving the White House and BRICS countries.
