Bandhan Bank Sees Sharp Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

On 27 Feb 2026, Bandhan Bank’s open interest (OI) in derivatives rose sharply to 35,468 contracts from 32,123 the previous day, marking an increase of 3,345 contracts or 10.41%. This surge is accompanied by a volume of 36,045 contracts, indicating robust trading activity. The futures segment alone accounted for a value of approximately ₹65,015 lakhs, while the options segment’s notional value stood at a substantial ₹17,683.76 crores, culminating in a total derivatives value of ₹69,741.45 lakhs.

The underlying stock price closed at ₹180, down 2.04% on the day, underperforming its private sector banking peers by 1.09% and the broader Sensex by 1.25%. Intraday, the stock touched a low of ₹177.68, a decline of 4.52%, with the weighted average price skewed towards the lower end of the day’s range. This price action, coupled with rising OI, suggests that while some investors are liquidating positions, others are building fresh exposure, possibly anticipating volatility or a directional move.

Market Positioning and Investor Behaviour

The increase in open interest alongside elevated volumes typically signals fresh capital entering the market rather than mere position unwinding. In Bandhan Bank’s case, the delivery volume on 26 Feb surged to 69.4 lakh shares, a near doubling (98.16%) compared to the five-day average, reflecting rising investor participation in the cash segment. This heightened delivery volume indicates genuine accumulation or distribution rather than speculative intraday trading.

Interestingly, Bandhan Bank is trading above its key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — which generally points to an underlying uptrend. However, the recent price dip after a five-day consecutive gain hints at profit booking or short-term correction. The mixed signals from price action and derivatives activity suggest that market participants are recalibrating their positions, possibly hedging against near-term risks while maintaining longer-term bullishness.

Implications of the Open Interest Surge

The 10.4% rise in open interest is significant for a stock with a market capitalisation of ₹28,885 crores, categorised as a small cap within the private sector banking industry. Such a jump often precedes notable price movements, as it reflects increased speculative or hedging activity. Traders may be positioning for an earnings announcement, regulatory update, or macroeconomic event impacting the banking sector.

Given the stock’s recent downgrade from a Sell to a Hold rating on 4 Feb 2026, with a Mojo Score of 51.0, investors appear to be cautiously optimistic. The upgrade in rating suggests some improvement in fundamentals or valuation appeal, but the Hold grade indicates limited upside in the near term. The market’s mixed signals are consistent with this stance, as participants weigh risks against potential gains.

Directional Bets and Potential Strategies

The derivatives data reveals that while the futures segment commands a sizeable portion of the open interest, the options market’s notional value dwarfs it, indicating active hedging and speculative strategies. The elevated option value of over ₹17,683 crores suggests that traders are employing complex strategies such as spreads, straddles, or protective puts to manage risk amid uncertain price direction.

Investors should note that the stock’s liquidity supports trades up to ₹4.48 crores based on 2% of the five-day average traded value, ensuring that sizeable positions can be entered or exited without significant market impact. This liquidity is crucial for institutional players who often drive open interest changes.

Given the current scenario, cautious investors might consider monitoring the stock for confirmation of trend direction before committing to fresh positions. The combination of rising open interest and volume, alongside a recent price pullback, could signal a consolidation phase before a potential breakout or breakdown.

Sector and Market Context

Bandhan Bank’s performance must be viewed within the broader private sector banking landscape, which has seen moderate volatility amid tightening monetary policies and evolving credit conditions. The stock’s 1D return of -2.04% contrasts with the sector’s -1.10% and Sensex’s -0.79%, indicating relative weakness on the day. However, the stock’s position above all major moving averages suggests that the medium to long-term trend remains intact.

Investors should also consider the bank’s fundamental metrics and recent rating changes. The upgrade from Sell to Hold by MarketsMOJO on 4 Feb 2026 reflects a reassessment of the bank’s prospects, possibly due to stabilising asset quality or improved earnings visibility. The Mojo Grade of Hold with a score of 51.0 indicates a neutral stance, advising investors to maintain positions but remain vigilant for further developments.

Conclusion: Navigating the Current Landscape

The surge in open interest and volume in Bandhan Bank’s derivatives market signals increased investor engagement and a potential build-up of directional bets. While the stock has experienced a short-term pullback, its position above key moving averages and rising delivery volumes suggest underlying strength. Market participants appear to be balancing cautious optimism with risk management, employing options strategies to hedge exposure amid uncertain near-term catalysts.

For investors, the current environment calls for careful monitoring of price action and derivatives trends. The mixed signals warrant a measured approach, with attention to upcoming corporate announcements and sector developments. Bandhan Bank’s Hold rating and moderate Mojo Score reinforce the need for prudence, while the liquidity and active derivatives market provide opportunities for tactical positioning.

Overall, the derivatives activity around Bandhan Bank highlights the nuanced market sentiment, blending speculative interest with hedging strategies. This dynamic underscores the importance of analysing open interest and volume patterns alongside price movements to gauge investor intent and potential future trends.
