DII Cushion Softens Blow as Persistent FII Selling and Global Headwinds Cap Expiry Day Recovery — September 29, 2026

Market Snapshot

Indian equities extended their losing streak for a second consecutive session on Tuesday, September 29, 2026, though headline indices staged a resilient recovery from steep morning troughs. Benchmark indices had tumbled in early trade, with the Nifty dropping to an intraday low of 22,569.65 and the Sensex diving over 700 points to touch 72,064. A late-session rebound trimmed the losses, driven by selective accumulation in pharmaceuticals and metals.

The closing figures for the session:

• NSE Nifty 50: Settled at 22,716.20, down 64.05 points (-0.28%).
• BSE Sensex: Closed at 72,529.07, declining 242.65 points (-0.33%).
• Broader Markets: Underperformed the frontline gauge; the BSE 150 MidCap Index slipped 0.74%, while the BSE 250 SmallCap Index fell 0.49%.
• Sectoral Trends: Nifty Consumer Durables (-2.14%), IT (-1.56%), and Realty (-1.25%) led the declines, while Nifty Metal (+0.78%) and Nifty Pharma (+0.64%) outperformed.

Institutional Flows: Cash Market

The tug-of-war between foreign institutional outflows and domestic institutional inflows remained the central dynamic defining market liquidity. Following an aggressive exit of ₹5,353.22 crore in the preceding session, foreign institutions continued their sustained divestment trend.

Institutional cash market provisional figures for September 29, 2026:

• Foreign Institutional Investors (FIIs/FPIs): Net sellers of ₹4,907 crore.
• Domestic Institutional Investors (DIIs): Net buyers of ₹4,754 crore.

Domestic mutual funds, insurance desks, and pension funds continued to act as a crucial shock absorber, deploying persistent SIP-led domestic inflows to counter foreign portfolio reallocations.

Derivatives Market Activity

Trading was dominated by the expiry of September monthly derivative contracts, leading to elevated volatility across strike prices:

• Rollover & Futures: The newly active October Nifty 50 futures contract settled at 22,893.20, commanding a healthy premium of 177 points over the spot close of 22,716.20, accompanied by a 28.1% surge in open interest to 17.35 million contracts.
• Put-Call Ratio (PCR): The overall Put-Call Ratio for the headline index hovered around 0.62, while the Bank Nifty PCR stood near 0.69, underscoring a call-heavy options open-interest posture and substantial overhead resistance.
• Options Structure: In the upcoming weekly series, the highest call open interest was concentrated around the 23,500 strike, with major put open interest clustered at the 22,000 strike, mapping the broad risk parameters for market participants.

Key Drivers and Outlook

The Indian market's cautious sentiment was shaped by multiple overlapping domestic and global factors:

• Spiking Energy Costs: Brent crude remained elevated around $105–$107 per barrel amid ongoing geopolitical tensions in West Asia and US-Iran frictions, raising concerns over India's trade deficit and imported inflation.
• Elevated Global Yields: The US 10-year Treasury yield hovered around 5.24%–5.27% (its highest tier in nearly two decades), strengthening the US dollar and encouraging risk-off foreign portfolio reallocation from emerging markets back into fixed-income securities.
• Currency Volatility: The Indian rupee faced persistent pressure, touching intraday lows near ₹96.15 per US dollar before settling marginally higher around ₹95.95, supported by reported intervention from the Reserve Bank of India.
• Primary Market Liquidity Absorption: An active pipeline of mega initial public offerings (IPOs) continued to absorb substantial secondary market liquidity.
• Index Rebalancing: The semi-annual index adjustment took effect at the close, seeing BSE Ltd entering the Nifty 50 index while Wipro exited.

Looking ahead, technical analysts suggest that while large-cap benchmarks have paused near their critical support at 22,600, a sustainable breakout requires reclaiming the 22,850–23,000 corridor. In the near term, market trajectories will remain sensitive to crude price movements, FII stabilization, and global interest rate signals.
