BANKNIFTY Options — Where Positioning Sits Today

Where BANKNIFTY open interest sits

The heaviest call open interest is at the 57,500 strike, holding 21,75,600 contracts — 14.5% of all BANKNIFTY call open interest on the board, 1.27% above the spot of 56,778. Call open interest concentrated above price is commonly read as resistance, on the reasoning that writers there are defending the level. It is a crowding observation, not a rule — the level holds until that open interest unwinds.

On the put side the weight is at 57,500 with 18,64,140 contracts, 13.9% of BANKNIFTY put open interest, 1.27% above spot. That strike is in the money, so it is not acting as support — price is already beneath it. Heavy in-the-money put open interest more often reflects protection bought before the move than a level being defended now.

What BANKNIFTY's PCR is saying

BANKNIFTY is carrying 1,33,81,080 contracts of put open interest against 1,50,33,030 of call, a put-call ratio of 0.89 — broadly balanced positioning. PCR has no universally good value; it is read against its own recent range, and the direction it is moving carries more than the level.

It opened the session at 0.97 and has fallen to 0.89 — a move of −0.08. Calls have been added faster than puts since the open, the reverse footprint — fresh call writing above spot, or puts being closed.

BANKNIFTY against its max pain

Max pain for BANKNIFTY computes to 57,500, with spot at 56,778 — 1.27% below it. That strike is where the total value of all open contracts expiring would be lowest. It is arithmetic on the current open interest distribution, not a forecast, and the distribution keeps changing.

The curve is defined around it: the nearest strike either side costs writers 2.3% more than 57,500. A trough that distinct is a stronger reference than a flat basin, though it still describes positioning rather than predicting settlement.

There are 21 sessions to expiry. This far out the figure moves as positions roll, and it is least informative early in a series — worth watching for direction of travel rather than as a target.

What changed in BANKNIFTY today

The largest fresh call position went on at 57,000, +2,70,210 contracts (+55.0%). Its premium fell over the same window, which is the footprint of call writing rather than call buying.

On the put side the heaviest addition is at 55,000, +1,18,740 contracts (+19.5%). Premium rose alongside it, which points to protection being bought rather than sold.

The biggest unwind is −1,36,110 put contracts at 57,300. Positions closing matters as much as positions opening — a level defended by open interest stops being defended when that open interest leaves, and a break through a strike that is unwinding is a different event from a break against one that is intact.

Change is measured against this session's opening snapshot rather than the previous close, so the overnight gap and the positions rolled at the open do not swamp the reading.

The move priced into BANKNIFTY

The at-the-money straddle on BANKNIFTY costs 1262.30 — 623.05 for the call and 639.25 for the put at the 57,100 strike. That sum is what the market charges to be covered in either direction, which makes it the move being priced in: about 2.22% of spot, or roughly 55,838 to 58,362 by expiry on a breakeven basis.

The straddle has moved −3.4% since the open. That is close to flat, so today's decay and any volatility move have roughly offset.

Implied volatility at the money is 11.7% on the call and 11.5% on the put. The two legs are priced almost identically, so there is no meaningful skew at the money right now.
