Foreign Institutional Investors (FIIs) intensified their selling in Indian equities on September 29, 2026, offloading shares worth Rs 9,980.22 crore in the cash market. The sharp FII outflow came amid continued weakness in the Indian stock market, elevated crude oil prices, higher US bond yields and ongoing geopolitical uncertainty.
According to provisional exchange data, Domestic Institutional Investors (DIIs) bought equities worth Rs 6,952.71 crore during the session. Despite strong domestic institutional buying, combined FII-DII activity resulted in a net institutional outflow of Rs 3,027.51 crore.
The latest FII selling was the largest single-day foreign outflow in nearly six months, highlighting the intensity of selling pressure in the Indian stock market as September comes to an end.
Nifty, Sensex Close Lower on September 29
Indian benchmark indices ended lower on Tuesday, September 29.
The Nifty 50 declined 64.05 points, or 0.28%, to close at 22,716.20, while the BSE Sensex fell 242.65 points, or 0.33%, to settle at 72,529.07. Both indices remained close to their recent six-month lows as investors continued to monitor global and domestic market risks.
Market volatility was also high during the session, with the Nifty witnessing significant swings around the monthly derivatives expiry.
FII Selling Accelerates in September 2026
The latest Rs 9,980.22 crore FII outflow adds to a broader selling trend that has persisted throughout September.
FIIs have been net sellers in 15 of the 20 trading sessions in September, taking their cumulative monthly selling to around Rs 33,864 crore by September 29. In contrast, DIIs have remained net buyers during all 20 trading sessions of the month, with cumulative purchases of approximately Rs 64,759 crore.
The recent acceleration in foreign selling is particularly notable. FIIs sold approximately Rs 3,693.93 crore on September 25, Rs 5,353.22 crore on September 28 and Rs 9,980.22 crore on September 29.
This has made FII activity and institutional flows key factors for investors tracking the Indian stock market in September 2026.
Why Are FIIs Selling Indian Stocks?
Several global and domestic factors are contributing to the pressure on Indian equities.
Rising Crude Oil Prices
Elevated crude oil prices remain one of the biggest concerns for the Indian economy and stock market. Brent crude was trading around the $105-per-barrel level, increasing concerns over India's import bill, inflation and corporate profit margins.
As India is heavily dependent on imported crude oil, sustained increases in international oil prices can influence the rupee, inflation expectations and investor sentiment.
Higher US Bond Yields
US Treasury yields have also emerged as an important factor behind global fund movements.
The US 10-year Treasury yield moved above 5.27%, reaching its highest level in years. Higher US yields can affect capital allocation decisions by global investors and contribute to pressure on emerging-market equities.
Geopolitical Uncertainty
Continuing uncertainty surrounding developments in the Middle East has added another layer of risk to global markets. Concerns over oil supplies and the broader economic impact of geopolitical tensions have kept investors cautious.
Rupee Weakness
Currency movement is another factor being closely watched by investors. The Indian rupee remained under pressure amid elevated oil prices and global uncertainty, increasing concerns around India's import costs.
DIIs Provide Support to Indian Stock Market
While FIIs have continued to withdraw money from Indian equities, domestic institutional investors have emerged as an important source of market liquidity.
DIIs purchased Rs 6,952.71 crore worth of equities on September 29. Their cumulative buying for September had reached approximately Rs 64,759 crore, more than offsetting the month's FII selling on a net institutional-flow basis.
This divergence between FII and DII activity has become one of the key themes of the Indian stock market in September 2026.
September 2026 Turns Into a Weak Month for Indian Markets
The sustained selling pressure has resulted in a significant monthly decline for India's benchmark indices.
According to market reports, both the Nifty 50 and Sensex were down around 6% during September, putting the month on course to be one of the weakest monthly performances for Indian equities in recent years. Reuters reported that the Nifty had already declined nearly 6% over the preceding seven weeks.
The combination of foreign fund outflows, higher crude prices, elevated global bond yields and geopolitical uncertainty has weighed on investor sentiment.
Budget 2027 Equity Tax Reports Draw Market Attention
Market participants are also keeping an eye on reports concerning possible changes to equity taxation in the Union Budget 2027.
However, reports suggesting potential equity tax cuts or changes should currently be treated as unconfirmed market speculation unless officially announced by the government. Investors have reacted differently to such reports, with market discussions ranging from expectations of a potential positive impact to caution over the lack of official confirmation.
What Investors Will Watch Next
As September comes to an end, investors are likely to closely monitor:
- FII and DII buying and selling data
- Nifty 50 and Sensex movement
- Crude oil prices
- Indian rupee-dollar movement
- US Treasury yields
- Global geopolitical developments
- Corporate earnings and economic data
- Any official announcements related to Budget 2027 and equity taxation
The latest FII selling data highlights the continued pressure on Indian equities. With FIIs selling nearly Rs 10,000 crore in a single session while DIIs bought nearly Rs 7,000 crore, institutional flows remain a crucial factor for the Indian stock market as September 2026 ends.
For investors and market participants, the direction of FII flows, crude oil prices, global bond yields and domestic institutional buying will remain important indicators to watch in the sessions ahead.
