Indian equity markets are witnessing a sharp divergence between foreign institutional investors (FIIs) and domestic institutional investors (DIIs), with overseas funds continuing to pull money out while domestic institutions step in as buyers. The contrasting flows have become an important factor limiting the impact of foreign selling and cushioning volatility in Indian equities.
The trend has become particularly visible in September 2026. On September 24 alone, FIIs sold ₹5,027.4 crore of Indian equities, while DIIs bought ₹4,301.2 crore, according to exchange data compiled by the Economic Times. Over the preceding 30 days, FIIs were net sellers of around ₹28,161 crore, whereas DIIs had invested approximately ₹64,528.6 crore.
The gap highlights a structural change in India’s market: domestic capital has become large enough to absorb a significant portion of foreign selling, although it has not completely eliminated the pressure created by global fund outflows.
FIIs Accelerate Selling as Global Risks Rise
Foreign investors have been under pressure from a combination of global and domestic factors.
FIIs sold ₹5,027.36 crore on September 24, their largest single-day outflow in September, according to NSE data reported by Upstox. September has seen foreign investors remain net sellers in most trading sessions, with the selling occurring against a backdrop of higher US bond yields, elevated crude-oil prices, geopolitical uncertainty and concerns surrounding the Indian rupee.
Economic Times analysis has similarly identified crude prices, US Treasury yields, geopolitical risks and currency concerns as important factors influencing foreign flows. Higher crude prices can be particularly significant for India because the country is heavily dependent on imports of crude oil.
When global bond yields rise, international investors can also reassess the relative attractiveness of emerging-market equities. Capital can move toward developed-market assets if investors perceive a better risk-return balance there.
September Shows the Growing Gap Between FIIs and DIIs
The monthly flow numbers show how strongly domestic institutions have been countering foreign selling.
As of September 24, FIIs had been net sellers in 12 of the month’s 17 trading sessions, with cumulative September selling reaching around ₹14,837 crore, according to Moneycontrol. During the same period, DIIs had purchased approximately ₹49,779 crore of equities.
Economic Times’ broader 30-day figures show an even larger difference, with DII purchases of ₹64,528.6 crore compared with FII selling of ₹28,161 crore.
The difference means domestic institutional investors are currently supplying a substantial amount of liquidity to the market at a time when foreign investors are reducing their exposure.
Domestic Funds Are Becoming a Major Market Force
The strength of DII buying is not simply a short-term September phenomenon. India’s domestic investment ecosystem has expanded considerably over the past several years.
According to data from the AMFI-Crisil Factbook 2026, DIIs purchased approximately ₹8.09 lakh crore of equities during FY2026, compared with FII selling of about ₹1.81 lakh crore. Domestic institutional purchases were therefore several times larger than the foreign outflows during that financial year.
Mutual funds have played an especially important role in this transformation.
The mutual-fund industry’s share of the free-float market capitalisation of NSE-listed companies increased to roughly 23% in March 2026, compared with about 15% in March 2021. The increase reflects the growing importance of domestic savings in India’s equity market.
SIPs Provide a Steady Source of Domestic Liquidity
One of the major drivers behind domestic fund flows has been the expansion of systematic investment plans, or SIPs.
SIP contributions reached a record approximately ₹32,087 crore per month in FY2026, while SIP assets under management crossed ₹14.83 lakh crore, according to the AMFI-Crisil data cited by Moneycontrol.
Unlike foreign portfolio flows, which can change rapidly in response to global interest rates, currencies and geopolitical events, SIP contributions tend to create a more predictable stream of domestic investment.
This does not mean domestic investors always buy regardless of market conditions. However, the recurring nature of SIP investments gives mutual funds a significant pool of capital that can be deployed into equities even during periods of foreign selling.
Domestic Institutions Cushion, But Do Not Eliminate Volatility
The current flow pattern does not mean Indian markets are immune to global shocks.
When foreign investors sell aggressively, benchmark indices can still experience sharp declines because FIIs remain important participants in India’s equity market. Their transactions can affect liquidity, sector rotation, currency expectations and short-term sentiment.
On September 24, for example, the Nifty 50 fell 1.64% to 23,063, while the Sensex dropped 1.67%, or around 1,248 points. The session was the worst for both benchmarks since March 9.
DII buying therefore acted as a counterweight rather than a complete shield.
The ability of domestic funds to absorb part of the foreign selling can reduce the potential depth of declines, but it cannot prevent volatility when global risk factors become sufficiently strong.
Why Foreign Investors Are Selling Indian Stocks
The reasons behind FII selling are broader than a single market trigger.
One major factor is the movement in US Treasury yields. Higher US yields can make dollar-denominated fixed-income assets more attractive relative to emerging-market equities.
Crude oil is another important factor. Rising oil prices can increase India’s import bill, put pressure on the current account and potentially create additional inflationary and currency pressures.
Geopolitical developments are also influencing investor behaviour. Economic Times reported that uncertainty surrounding the Iran-US conflict, along with its potential impact on oil prices, remains an important factor for foreign flows.
The rupee is another consideration. Currency depreciation can reduce the dollar value of returns earned by foreign investors, making them more cautious about additional Indian-equity exposure.
FII Selling Is Not Uniform Across the Market
Another important feature of the current trend is that foreign investors are not necessarily abandoning all Indian assets.
Economic Times reported that foreign investors continued to show interest in India’s primary market, even while selling in the secondary equity market. Foreign capital flowing into IPOs and fresh listings has remained relatively strong.
This creates an interesting divergence: global investors may be reducing exposure to established listed stocks while still participating in selected new offerings.
India’s record IPO activity in September has therefore continued even as the broader stock market has faced pressure from FII selling.
DIIs Have Repeatedly Stepped In During Market Weakness
Recent daily flow data provides several examples of the domestic counterweight.
On September 22, FIIs sold approximately ₹3,810 crore, while DIIs bought around ₹4,120 crore. By that point, September’s cumulative FII selling had reached roughly ₹11,427 crore, while DII buying had climbed to about ₹43,136 crore.
Earlier, on September 15, FIIs sold approximately ₹2,978 crore, while DIIs purchased around ₹2,686 crore. By then, DIIs had already invested around ₹27,673 crore during September.
The repeated pattern shows that domestic institutions have been providing liquidity during several sessions in which foreign investors were net sellers.
What the FII-DII Battle Means for the Market
The changing balance between foreign and domestic flows is becoming one of the most important structural stories in Indian equities.
Historically, large FII outflows could create substantial pressure because domestic institutions did not have enough capital to offset them. India’s rapidly expanding mutual-fund industry has changed that equation.
The growing domestic investor base means Indian equities now have a larger pool of locally sourced capital capable of absorbing foreign selling.
However, the two groups often respond to different factors. Foreign investors are highly sensitive to global rates, currencies, commodity prices and international risk appetite, while domestic institutions are more closely connected to India’s savings flows, earnings outlook and domestic economic conditions.
September Highlights India’s Changing Market Structure
The latest September data provides a clear illustration of this evolving market structure.
Foreign investors have continued to sell, with ₹5,027 crore of FII outflows on September 24 alone, while domestic institutions purchased ₹4,301 crore that day. Over the previous 30 days, the gap was even wider, with DIIs buying around ₹64,529 crore against FII selling of roughly ₹28,161 crore.
Domestic funds cannot completely neutralise global risk, and the September 24 market decline demonstrates that clearly. But the scale of DII buying is providing an important source of stability.
As India’s mutual-fund industry, SIP participation and domestic financial savings continue to expand, the ability of local institutions to absorb foreign selling is likely to remain a major feature of the country’s equity market.
For investors and market watchers, the FII-DII flow gap has therefore become more than a daily statistic. It is increasingly a measure of how India’s domestic capital base is changing the way the country’s stock market responds to global volatility.
