Indian equity markets experienced notable declines on August 8, 2025, amid escalating trade tensions with the United States. The BSE Sensex fell by 765.47 points to close at 79,857.79, while the Nifty 50 dropped 232.85 points, settling below the 24,450 mark. The downturn followed US President Donald Trump's announcement ruling out any trade negotiations with India until the ongoing tariff dispute is resolved. The US has imposed a 50% tariff on Indian exports, contributing to market pressure alongside foreign institutional investor selling and a weakening rupee. Key stocks such as Bharti Airtel, Adani, and Axis Bank were among those affected. This decline marks the longest weekly losing streak for the Sensex and Nifty in five years, driven by concerns over the trade war and earnings outlook.
