DIIs Counter Heavy FII Outflows: Domestic Funds Pump ₹4,120 Crore as Foreign Sellers Offload ₹3,810 Crore

Market Snapshot

The trading session on Tuesday, September 22, 2026, witnessed another intense showdown between foreign institutional participants and domestic asset managers. While benchmark indices traded within a tight and volatile band, the underlying institutional tug-of-war highlighted contrasting views on Indian equities. The sustained divergence between offshore risk-off sentiment and disciplined domestic capital deployment continues to define market dynamics in late September.

Institutional Flows: Cash Market

According to provisional exchange data across NSE and BSE, Foreign Institutional Investors (FIIs) remained aggressive net sellers in the cash segment, offloading shares worth ₹3,809.99 crore. Conversely, Domestic Institutional Investors (DIIs) maintained their buying momentum, absorbing foreign supplies with a net inflow of ₹4,120.07 crore.

Key provisional cash market figures for September 22, 2026:

• FII Gross Purchases: ₹9,845.81 crore
• FII Gross Sales: ₹13,655.80 crore
• FII Net Cash Activity: -₹3,809.99 crore (Net Sell)
• DII Gross Purchases: ₹14,599.72 crore
• DII Gross Sales: ₹10,479.65 crore
• DII Net Cash Activity: +₹4,120.07 crore (Net Buy)
• Combined Institutional Net Flow: +₹310.08 crore

Month-to-date figures show FII cash withdrawals exceeding ₹11,400 crore for September, whereas DIIs have accumulated over ₹43,100 crore in net purchases over the same period, providing substantial support to domestic equities.

Derivatives Market Activity

Derivatives positioning on September 22 mirrored the cautious stance observed in the cash segment:

• Index Futures: FIIs demonstrated a distinctly cautious outlook at the index level, selling 338,277 index contracts against 47,731 contracts purchased, pointing to fresh short additions and hedge creations on the broader indices.
• Stock Futures: In contrast to their headline index stance, institutional participants showed selective optimism in stock-specific futures, with FIIs logging over 3.45 million buy contracts versus 2.95 million sell contracts, indicating active rotation into select large-cap and mid-cap ideas.
• Index Options: Put buying picked up noticeably, with FIIs acquiring over 1.39 million put option contracts compared to 755,240 sold contracts. The aggressive build-up of downside protection underlines apprehension ahead of upcoming weekly derivative expiries and key macroeconomic events.

Key Drivers and Outlook

The institutional divergence reflects two contrasting structural drivers:

• Global Macro Headwinds & Dollar Trends: Ongoing consolidation in global asset classes, elevated US bond yields, and currency fluctuations continue to prompt foreign portfolio managers to trim exposure across emerging markets, including India.
• Systemic Domestic SIP & Pension Inflows: Robust systematic investment plan (SIP) flows and consistent allocations from domestic mutual funds, insurance houses, and pension funds have created a strong liquidity safety net, allowing DIIs to absorb overseas supply without causing structural breakdowns in the broader trend.

Outlook: Looking forward, market participants should monitor whether FII selling moderates near key technical support zones for the Nifty and Sensex. While the underlying domestic liquidity remains robust, elevated index hedging and high short exposure in index futures suggest volatility could remain heightened in the near term. A sustained pullback in institutional selling will be critical for any decisive upward breakout.
