NSE & BSE Indices Futures and Options Open Interest Volume Analysis for 22/08/2025

Table of Contents
The Open Interest Volume Analysis for 22nd August 2025 reveals a clear risk-off mood as the market heads into the final stretch before expiry. Nifty August futures slid 0.89% to 24,898.20, while open interest tumbled by 5.6%, marking a significant round of position unwinding and profit booking. The premium narrowed by nearly 11 points, underscoring fading upside conviction. On the options front, the Put-Call Ratio (OI) collapsed to a weak 0.61, with heavy call writing at the 25,000 strike and new puts only slightly defending 24,900—showing bears are gradually taking charge and positioning for a possible test of lower support. Max pain has now drifted to 24,950, making it the key expiry anchor for the coming week.
BankNifty showed an even sharper contrast: futures lost more than 1%, but open interest actually rose over 3.5%, clearly suggesting fresh short positions as bears increase their grip on financials. Put-Call ratios here also dropped sharply, with 57,000 call OI vastly outnumbering put support—setting up for more near-term turbulence. FINNIFTY echoed Nifty’s story, falling by nearly 1% as open interest fell and premium stayed near recent highs; here too, put-call ratios slipped and max pain sits at 26,500. MIDCPNIFTY managed to stay flat but open interest shrank, a signal that the recent outperformance in midcaps may pause as expiry and volatility spike. SENSEX reflected the overall nervousness, posting a 0.85% fall along with a dip in open interest, showing broader caution and rotation ahead of monthly settlement.

Conclusion: What the NSE & BSE Indices Futures and Options Open Interest Volume Analysis Tells Us
This session’s Open Interest Volume Analysis signals that sellers are back in control as traders lock in profits and avoid new risk heading into expiry. For Nifty, expect expiry action to center around the 24,900–25,000 zone, with further downside likely if 24,900 consistently gives way—look to bear call spreads and credit call strategies above 25,000 as the preferred play. BankNifty is flashing even stronger warning signs—stay defensive until open interest and put support start to revive. In FINNIFTY and MIDCPNIFTY, keep positions light and take profits actively as volatility and uncertain sentiment dominate. As the contract winds down, let this Open Interest Volume Analysis be your guide: focus on risk control, consider range and short-side setups, and be wary of chasing late upside in a market that’s turning cautious as expiry pressure mounts.
