Indian stock markets ended flat on August 21, 2026, with the BSE Sensex closing at 77,540.83 and the NSE Nifty at 24,252.23

Investor sentiment remained cautious due to elevated crude oil prices and geopolitical uncertainties, particularly the ongoing standoff between the U.S. and Iran, which has kept oil prices high, impacting major importing economies like India.

Hariselvan Radhakrishnan, CEO of HST Wealth, noted, "The renewed rise in U.S. bond yields has added another layer of uncertainty, despite the Treasury's expanded debt-buyback programme."

Sector-wise, Insurance and Utilities saw gains, while Auto and Housing Finance faced declines. The BSE benchmark fell 468.42 points, or 0.60%, over the week.
