Fin Nifty

Fin Nifty (Nifty Financial Services) is an NSE index of major financial stocks, with its own actively traded F&O contracts.

Fin Nifty tracks banks, NBFCs, insurance, and other financial-sector companies, with heavyweights like HDFC Bank and ICICI Bank dominating its weight. It is cash-settled like other index contracts and has become a popular F&O underlying alongside Nifty and Bank Nifty.

Indian option traders use Fin Nifty for its weekly expiry and its concentrated exposure to the financial sector, which is highly sensitive to interest rates and credit cycles. Following SEBI's move to limit weekly expiries to one per exchange, traders should check the current expiry calendar, as contract schedules have been rationalised.
