History
The development of NSE indices began following the establishment of the National Stock Exchange of India in the early 1990s. The launch of the NIFTY 50 in 1996 provided India with a transparent benchmark representing large-cap companies listed on the exchange.
To strengthen index governance and expand index-related services, the responsibility for administering NSE indices was transferred to a dedicated subsidiary, NSE Indices Limited. The company subsequently broadened its range of indices to include benchmarks covering different market capitalizations, sectors, investment strategies, environmental, social and governance (ESG) criteria, fixed-income securities, and thematic investments.
Today, NSE Indices Limited serves as one of India's principal index providers, supporting domestic and international investment products linked to Indian financial markets.
