Nifty Bank Index Today
The Bank Nifty level, its valuation against its own year, and how smart money is positioned in every constituent bank - OI buildup, delivery, deals and trend - from NSE's own data.
The Nifty Bank index tracks the most liquid, largest listed Indian banks on the NSE. This page shows the index level and its day, week and month move, where it sits in its 52-week range, its P/E and P/B against its own past year, and every constituent with its price, F&O open-interest buildup, delivery percentage and trend - plus 30 days of bulk and block deals in bank stocks and the Bank Nifty option chain's put-call ratio and max pain.
Nifty Bank - the index most traders simply call Bank Nifty - holds the largest and most liquid banks listed on the NSE, private and public sector, weighted by free-float market capitalisation. Large private lenders such as HDFC Bank, ICICI Bank, Kotak Mahindra Bank and Axis Bank sit alongside State Bank of India and other public-sector banks. Because banks are among the heaviest weights in the Nifty 50 as well, the direction of this one sector does a great deal to set the direction of the whole market.
Most pages stop at the index level. This one adds the part that tells you who is moving the sector: for every constituent bank, its open-interest buildup in the F&O market, how much of today's volume was taken for delivery, whether it trades above its 200-day average, and the bulk and block deals done in bank stocks over the last 30 days. Those are the footprints institutions leave, and they are all published by the exchange.
Everything comes from NSE-published files: the index level and valuation from NSE's end-of-day index file, constituents from NSE's own constituent list, open interest from the F&O bhavcopy, delivery from the security-wise delivery file, and deals from NSE's bulk and block deal disclosures.
How to read the positioning in bank stocks
Start with the open-interest buildup mix. Every bank in the F&O segment is classified each session by how its price and its futures open interest moved together. Rising price with rising open interest is long buildup - fresh money betting on the upside. Rising price with falling open interest is short covering - shorts leaving, which lifts price without new conviction behind it. Falling price with rising open interest is short buildup, and falling price with falling open interest is long unwinding.
Read the count across the sector, not one name. When most banks show long buildup on an up day, the move has fresh positions behind it. When the index rises on mostly short covering, it is a squeeze rather than a new trend, and squeezes fade more often than buildups do. The tilt shown in the smart-money panel is simply which side has more names.
Then check delivery. A high delivery percentage means a larger share of the day's volume changed hands for keeps rather than being traded intraday. A bank delivering far above its own average - marked with a triangle in the table - is seeing genuine accumulation or distribution, and the price direction tells you which.
Finally, the deal flow. Bulk and block deals are the largest disclosed trades, and in bank stocks they are usually institutions - mutual funds, insurers, foreign portfolio investors - adjusting big positions. A sector that has been bought on net over 30 days while its index lagged is a different picture from one that is rising while institutions sell into it.
What moves banks in India
Interest rates come first. The RBI's policy rate and system liquidity set the cost of a bank's funds and the yield on its loans, and the gap between the two - the net interest margin - is the core of bank earnings. Rate cuts can squeeze margins in the short run when loans reprice faster than deposits, and the reverse holds when rates rise. Policy days and liquidity data move the index accordingly.
Credit growth and deposit growth follow. Banks grow earnings by lending more, but only as fast as they can raise deposits; when loans outrun deposits, banks compete harder for funds and margins narrow. The share of low-cost current and savings deposits is one of the clearest differences between the strongest and weakest lenders.
Asset quality is the third driver - gross and net non-performing assets and the provisions banks set aside for them. The sector re-rates sharply when bad loans fall and de-rates when they rise. Public-sector banks tend to swing harder on this than the large private banks.
Foreign investor flows matter more here than in most sectors, because the large private banks are among the most widely held Indian stocks by foreign portfolio investors. When foreign money leaves Indian equities, bank heavyweights are often the first names sold, which is why the FII/DII data and the bank index tend to move together.
Why P/B matters more than P/E for banks
For most sectors the price-to-earnings ratio is the first valuation check. For banks, the market usually leans on price-to-book, because a bank's balance sheet is its business: book value is the capital that supports its lending, and earnings swing with provisions in a way book value does not.
This page shows both, and places today's P/E against the index's own record over roughly the last year of sessions - the percentile, the low, the median and the high. A reading near the top of its own range says the sector is priced richly against its recent self; near the bottom, cheaply. That is context, not a buy or sell signal: valuation can stay stretched or depressed for a long time.
Bank Nifty options and this page
Bank Nifty is one of India's most actively traded index derivatives, and the option chain carries its own information - the put-call ratio and the max-pain strike summarise where option writers are positioned. The smart-money panel above shows both from the latest chain, and the full chain with Greeks is on the Bank Nifty option chain page.
The constituent table links each bank to its full stock page, where the same positioning signals appear with a longer history, and each OI label links to the screen that lists every stock in that state today.
Where this data comes from
The index level, points change, percentage change, P/E, P/B and dividend yield come from NSE's daily all-indices end-of-day file. The constituent list comes from NSE's own Nifty Bank constituent file. Open-interest buildup is computed from the NSE F&O bhavcopy for the latest completed session, delivery from NSE's security-wise delivery file, and bulk and block deals from NSE's daily disclosures.
Index values are end-of-day; constituent prices are the latest available during the session. NSE does not publish index weights in its constituent file, so this page shows none rather than estimate them. Read our methodology for how each signal is computed.
Key takeaways
- Nifty Bank holds the largest, most liquid listed Indian banks, weighted by free-float market capitalisation.
- Banks are among the heaviest Nifty 50 weights, so this sector often sets the direction of the whole market.
- Read OI buildup across the sector: long buildup is fresh conviction, short covering is a squeeze.
- Delivery far above a bank's own average marks genuine accumulation or distribution.
- For banks, price-to-book usually matters more than P/E; this page shows both against the index's own year.
- Every figure comes from an NSE-published file; positioning describes what happened, not what happens next.
Frequently asked questions
What is the Nifty Bank index?
Nifty Bank, widely called Bank Nifty, is an NSE sectoral index of the largest and most liquid listed Indian banks, private and public sector, weighted by free-float market capitalisation. It includes banks such as HDFC Bank, ICICI Bank, State Bank of India, Kotak Mahindra Bank and Axis Bank.
Which stocks are in Bank Nifty?
The constituent table on this page is generated directly from NSE's published Nifty Bank constituent file, so it always matches the current index, including after NSE's periodic rebalancing. Each bank links to its own page with prices, deals and F&O data.
What does long buildup in bank stocks mean?
Long buildup means a stock's price and its futures open interest both rose in the session - new positions were opened on the long side. When most banks in the index show long buildup on the same day, the sector's move has fresh positions behind it rather than just short covering.
Where can I see the Bank Nifty P/E and P/B ratio?
In the index summary at the top of this page, from NSE's daily index file. The page also shows where today's P/E sits against the index's own record over roughly the last year of sessions. For banks, price-to-book is usually the more useful of the two.
Are institutions buying or selling bank stocks?
The smart-money panel shows what FIIs, mutual funds, insurers and sovereign funds bought and sold in Nifty Bank stocks through bulk and block deals over the last 30 days, the net, and the largest of those deals with their counterparties. These are the largest disclosed trades, usually by institutions. They are a partial view: most institutional trading happens below the disclosure threshold.
What is the Bank Nifty PCR today?
The put-call ratio from the latest Bank Nifty option chain appears in the smart-money panel, alongside the max-pain strike and expiry. The full chain, with strike-wise open interest and Greeks, is on the Bank Nifty option chain page.
How often is this page updated?
The index level and valuation update from NSE's end-of-day file after each session. OI buildup and delivery update when NSE publishes the session's F&O bhavcopy and delivery file in the evening. Constituent prices update during the session. Each block shows the date of the data it uses.
