Indian Markets Buoyed by DII Inflows as FIIs Exit on September 17th; September 18th Provisional Data Pending

Market Snapshot

The Indian equity market concluded September 17, 2025, on an optimistic note, with key indices registering gains. The NSE Nifty 50 advanced by 90 points, or 0.36%, to close at 25,330, while the BSE Sensex climbed 313 points, or 0.38%, reaching 82,694. This positive momentum was largely supported by favorable global developments, including the US Federal Reserve's decision to cut interest rates. Asian markets also opened higher on September 18, 2025, reflecting overnight gains on Wall Street.

Institutional Flows: Cash Market

As of September 17, 2025, provisional data revealed a clear divergence in the trading activity of institutional investors in the Indian cash equity market.

• Foreign Institutional Investors (FIIs) were net sellers, offloading shares worth ₹1,124.54 crore.
• Conversely, Domestic Institutional Investors (DIIs) emerged as significant net buyers, injecting ₹2,293.53 crore into the market.

It is crucial to note that the provisional FII and DII data for the cash segment of September 18, 2025, is typically released by stock exchanges and regulatory bodies after the market concludes its trading session. While some platforms may offer real-time indicators, consolidated provisional figures for the current day's cash market activity were not yet widely disseminated in the available search results at the time of this report.

Derivatives Market Activity

Based on the available provisional data for September 17, 2025, FIIs exhibited mixed activity in the derivatives segment.

• In Index Futures, FIIs recorded a net buy position of +₹1,708.09 crore.
• However, FIIs were net sellers in Index Options, with a figure of -₹3,533.23 crore.
• Stock Futures saw FIIs as net sellers, with an outflow of -₹401.79 crore.
• Similarly, FIIs registered net selling in Stock Options, totaling -₹30.68 crore.

Key Drivers and Outlook

The recent market performance has been significantly shaped by international economic policy. The US Federal Reserve's decision to implement its first interest rate cut of 2025, reducing the lending rate by 25 basis points to a range of 4%-4.25%, played a pivotal role in boosting global investor sentiment. Fed Chairman Jerome Powell characterized this as a "risk management cut," indicating potential for additional rate adjustments throughout the year.

The sustained buying by DIIs underscores robust domestic confidence and liquidity within the Indian market, providing a vital buffer against foreign capital outflows. As the market awaits the official provisional data for September 18, 2025, institutional investor behavior will be closely scrutinized for insights into the immediate impact of these global and domestic financial developments.
