Sensex, Nifty Fall as US-Iran Peace Talks in Geneva Stall

Indian equity benchmarks declined on Wednesday, May 27, 2026, as investors turned cautious after US-Iran nuclear negotiations in Geneva hit an impasse. The S&P BSE Sensex fell 0.4% to 68,112.48, while the NSE Nifty 50 slipped 0.3% to 20,745.30. Markets tracked a broader Asian sell-off as diplomatic sources indicated talks over sanctions relief and uranium enrichment limits had stalled, raising the risk of renewed Middle East instability. Brent crude futures held steady around $79 a barrel, failing to provide a floor for stocks. Financial and IT names led the decline, with HDFC Bank and Infosys each down over 0.5%. Defensives like Sun Pharma and Hindustan Unilever posted modest gains. ``The market is hostage to headline risk from Geneva. Any sign of a deal could trigger a sharp reversal, but for now, there is no clear catalyst,'' said a Mumbai-based strategist at a foreign brokerage.
