Union Bank of India Sees Sharp Open Interest Surge Signalling Bullish Market Positioning

Open Interest and Volume Dynamics

On 15 Jul 2026, Union Bank of India’s open interest (OI) in derivatives rose sharply to 65,164 contracts, up 8,202 contracts or 14.4% from the previous day’s 56,962. This substantial increase in OI indicates fresh positions being established, reflecting heightened trader interest and possibly new directional convictions. The volume for the day stood at 95,405 contracts, underscoring active participation in the futures and options market.

The futures value traded was ₹1,59,551.82 lakhs, while the options segment saw an enormous notional value of ₹59,393.54 crores, culminating in a total derivatives turnover of ₹1,73,899.48 lakhs. Such elevated turnover levels highlight the stock’s liquidity and attractiveness among derivatives traders.

Price Performance and Technical Positioning

Union Bank’s underlying share price closed at ₹172, having touched an intraday high of ₹177.49, marking a 4% rise on the day. The stock has been on a consistent upward trajectory, gaining 12.22% over the past five trading sessions. This streak of consecutive gains is a strong technical signal, suggesting sustained buying interest.

Technically, the stock trades above its 5-day, 20-day, 50-day, and 200-day moving averages, though it remains below the 100-day moving average. This positioning indicates short- to medium-term bullishness, tempered by some resistance at longer-term levels. The weighted average price for the day was closer to the low, implying that while volumes were strong, some profit booking or cautious selling occurred near the highs.

Market Positioning and Investor Sentiment

The surge in open interest combined with rising prices suggests that market participants are increasingly bullish on Union Bank of India. The derivatives activity points to fresh long positions being built, possibly anticipating further upside in the stock. However, delivery volumes tell a slightly different story; on 14 Jul, delivery volume was 62.97 lakh shares, down 27.66% compared to the five-day average. This decline in delivery participation may indicate that some investors are opting for short-term trading strategies rather than long-term accumulation.

Despite this, the stock’s dividend yield remains attractive at 5.69%, providing an additional incentive for investors seeking income alongside capital appreciation. The bank’s large-cap status and a market capitalisation of ₹1,31,374 crore further enhance its appeal as a stable investment within the public sector banking space.

Mojo Score Upgrade Reflects Positive Outlook

MarketsMOJO has upgraded Union Bank of India’s Mojo Grade from Hold to Buy as of 13 Jul 2026, reflecting improved fundamentals and technicals. The bank’s Mojo Score stands at a robust 74.0, signalling strong potential for further gains. This upgrade aligns with the recent surge in derivatives activity and price momentum, reinforcing the stock’s attractiveness to investors.

As a large-cap public sector bank, Union Bank benefits from government backing and a stable asset quality profile, factors that contribute to its favourable rating. The sector’s 1-day return of 1.35% and Sensex’s 0.41% gain on the same day further contextualise the bank’s outperformance, with Union Bank delivering a 2.92% return.

Implications of Open Interest Surge for Directional Bets

The 14.4% increase in open interest is a critical indicator of changing market positioning. Traders appear to be taking fresh long positions, anticipating continued upward price movement. This is supported by the stock’s five-day consecutive gains and strong relative performance versus the sector and benchmark indices.

However, the divergence between rising derivatives activity and falling delivery volumes suggests a nuanced market stance. While speculative interest is rising, some long-term investors may be exercising caution or taking profits. This mixed participation could lead to increased volatility in the near term, as market participants digest fresh information and adjust their positions accordingly.

Liquidity and Trading Considerations

Union Bank’s liquidity remains healthy, with the stock capable of handling trade sizes up to ₹6.81 crore based on 2% of the five-day average traded value. This ensures that institutional and retail investors can transact sizeable volumes without significant price impact, an important factor for derivatives traders and long-term investors alike.

The stock’s high dividend yield of 5.69% adds an income dimension to its investment case, making it attractive for dividend-focused portfolios amid a rising interest rate environment.

Outlook and Investor Takeaways

Union Bank of India’s recent surge in open interest and sustained price gains signal a positive near-term outlook. The upgrade to a Buy rating by MarketsMOJO and the strong Mojo Score of 74.0 provide further validation of the bank’s improving fundamentals and technical strength.

Investors should monitor the evolving derivatives positioning closely, as the rising open interest suggests increased speculative interest that could amplify price movements. The divergence between delivery volumes and derivatives activity warrants caution, indicating that while momentum is strong, some profit-taking or consolidation may occur.

Given the bank’s large-cap status, attractive dividend yield, and improving technical setup, Union Bank remains a compelling option for investors seeking exposure to the public sector banking sector with a blend of growth and income potential.

Summary

In summary, Union Bank of India’s derivatives market activity reveals a significant build-up of fresh positions, reflecting bullish sentiment. The stock’s price action, combined with a recent Mojo Grade upgrade and strong liquidity, supports a constructive investment thesis. Market participants should weigh the positive momentum against the nuanced delivery volume trends to make informed decisions.
