Open Interest and Volume Dynamics
On 27 Jan 2026, Bandhan Bank Ltd. (symbol: BANDHANBNK) recorded an open interest (OI) of 50,777 contracts, up from 46,050 the previous day, marking an absolute increase of 4,727 contracts or 10.26%. This rise in OI was accompanied by a futures volume of 29,820 contracts, indicating robust trading activity in the derivatives market. The futures value stood at ₹1,07,655.93 lakhs, while the options segment contributed a substantial ₹5,469.04 crores, culminating in a total derivatives value of approximately ₹1,09,094.73 lakhs.
The underlying equity price closed at ₹148, marginally down by 0.19% on the day, underperforming the private sector banking sector which gained 0.22%, and the Sensex which rose 0.30%. This divergence between derivatives activity and spot price movement suggests that traders may be positioning for potential volatility or directional shifts in the near term.
Market Positioning and Sentiment Analysis
The surge in open interest typically reflects fresh capital entering the market or existing positions being rolled over, often signalling increased conviction among participants. In Bandhan Bank’s case, the 10.26% OI increase alongside a futures volume of nearly 30,000 contracts points to active repositioning by institutional and retail traders alike.
However, the stock’s price trend reveals a nuanced picture. After two consecutive days of gains, Bandhan Bank’s share price reversed, falling slightly despite rising investor participation. Notably, the delivery volume on 23 Jan surged to 2.67 crore shares, a staggering 479.1% increase over the five-day average delivery volume, indicating strong investor interest in holding the stock amid short-term price fluctuations.
Technical indicators show the stock trading above its 5-day, 20-day, and 50-day moving averages, signalling short- to medium-term strength. Yet, it remains below its 100-day and 200-day moving averages, suggesting that longer-term momentum has yet to fully recover. This mixed technical backdrop may be contributing to the cautious stance among traders reflected in the derivatives market.

Directional Bets and Potential Market Implications
The increase in open interest combined with a slight price decline suggests that market participants may be hedging or speculating on a potential downward correction despite recent gains. The derivatives data does not indicate a clear directional bias but rather a heightened state of alertness among traders.
Given the stock’s current mojo score of 38.0 and a downgrade from Hold to Sell as of 31 Oct 2025, investor sentiment appears cautious. The market cap of ₹24,011.53 crore classifies Bandhan Bank as a small-cap entity, which often entails higher volatility and sensitivity to sectoral and macroeconomic developments.
Liquidity remains adequate, with the stock supporting trade sizes up to ₹6.52 crore based on 2% of the five-day average traded value, facilitating active participation from institutional players. This liquidity, coupled with rising delivery volumes, underscores the stock’s appeal despite its recent underperformance.
Sector and Broader Market Context
Bandhan Bank operates within the private sector banking industry, a segment that has shown resilience but also faces headwinds from regulatory changes and competitive pressures. The stock’s underperformance relative to its sector and the Sensex on the day highlights the challenges it faces in regaining investor confidence.
Investors should note that while short-term derivatives activity signals increased interest and potential volatility, the longer-term technical indicators and fundamental mojo grade suggest a cautious approach. The downgrade to Sell reflects concerns over earnings momentum and valuation metrics relative to peers.

Investor Takeaway
For investors and traders, the recent surge in Bandhan Bank’s derivatives open interest signals a period of increased activity and potential volatility. While the stock’s short-term technicals show some strength, the overall mojo grade downgrade and underperformance relative to sector peers counsel prudence.
Market participants should closely monitor open interest trends alongside price action and volume patterns to gauge evolving sentiment. The elevated delivery volumes suggest that long-term investors remain engaged, but the derivatives market’s mixed signals imply that directional conviction is yet to solidify.
Given the current environment, a cautious stance with a focus on risk management is advisable. Investors may consider exploring alternative private sector banking stocks with stronger fundamentals and momentum profiles, as identified by comprehensive multi-parameter analyses.
Conclusion
Bandhan Bank Ltd.’s recent open interest surge in derivatives highlights a dynamic market landscape where traders are actively repositioning amid mixed signals. The stock’s downgrade to Sell and modest price decline contrast with rising investor participation, underscoring the complexity of current market sentiment.
As the private sector banking sector continues to evolve, Bandhan Bank’s performance and market positioning will remain under close scrutiny. Investors should weigh the derivatives activity alongside fundamental and technical factors to make informed decisions in this small-cap banking stock.
