Nifty Bank
Nifty Bank, also known as Bank Nifty, is a sectoral index maintained by NSE Indices Limited that tracks the performance of the most liquid and large Indian banking stocks listed on the National Stock Exchange, serving as the primary benchmark for India's banking sector.
Nifty Bank was launched by NSE on 15 September 2003, with a base date of 1 January 2000 and a base value of 1,000. The index comprised twelve Indian banking stocks selected based on free-float market capitalisation and liquidity criteria. These typically included the largest private and public sector banks in India — such as HDFC Bank, ICICI Bank, Axis Bank, Kotak Mahindra Bank, State Bank of India, IndusInd Bank, Bank of Baroda, and others. The index was rebalanced semi-annually by NSE Indices Limited.
The significance of Nifty Bank in the Indian equity ecosystem was considerable. Banking and financial services collectively accounted for the largest sectoral weight in the Nifty 50 — often exceeding 35–40% of the total index weight — meaning that the performance of major banks had an outsized influence on the broad market. Nifty Bank offered a focused lens on the health of India's credit economy: when credit growth was strong, NPAs were falling, and NIMs (net interest margins) were expanding, Nifty Bank outperformed the broader Nifty 50. During credit stress cycles, it underperformed sharply.
Between 2013 and 2018, Nifty Bank delivered exceptional performance as private sector banks gained market share from PSU banks struggling with NPAs. The asset quality review (AQR) initiated by RBI in 2015–16 forced PSU banks to recognise hidden bad loans, dragging down PSU bank valuations significantly while private banks continued to compound. After 2020, as credit cycles turned and economic recovery accelerated post-COVID, several PSU banks regained significant ground, and Nifty Bank reflected this broader banking sector revival.
For fundamental investors, Nifty Bank served as a benchmark for banking sector fund performance and as a reference for sector-rotation decisions. Fund managers and analysts tracked the composition and historical performance of Nifty Bank to understand relative sector valuations. As the underlying index for Bank Nifty futures and options, it also served as the most actively traded derivative product in India after Nifty 50 options.
Nifty Bank and Bank Nifty are two names for the same index, used interchangeably across financial media, trading platforms, and analytical reports. The distinction between 'Nifty Bank' as the index and 'Bank Nifty' as the derivative product is colloquial; both refer to the same underlying index series.
