BENGALURU, Dec 13 (Reuters) - India's benchmark Nifty 50 opened little changed on Wednesday after domestic and U.S. data reignited inflation concerns and elevated bets of a delay in rate cuts, ahead of Federal Reserve's policy decision.

The NSE Nifty 50 index shed 0.07% to 20,891.50 points, while the S&P BSE Sensex fell 0.05% to 69,503.33, as of 9:16 a.m. IST. (Reporting by Bharath Rajeswaran in Bengaluru; Editing by Janane Venkatraman and Sonia Cheema)
