DIIs vs FIIs: How domestic money steadied markets in 2026

Domestic investors have become the market’s shock absorber

Data from 2018 through the first half of 2026 highlights a clear shift in India’s equity market structure. Domestic Institutional Investors (DIIs) have become a larger and more consistent counterweight to Foreign Institutional Investors (FIIs) during risk-off phases. While FIIs still move sentiment quickly, DIIs have repeatedly stepped in during periods of heavy foreign selling. The pattern is especially visible after 2021, when domestic flows increasingly absorbed large FII outflows. By the end of H1 2026, FIIs had already sold more than they did in the whole of 2025, yet domestic buying continued to provide support. The first half of 2026 also saw a clear market drawdown, with the Nifty 50 down nearly 9%, underlining that domestic support does not eliminate volatility but can soften it.

What changed since 2021: DIIs increasingly offset FII outflows

The recent years tell a different story than the older assumption that foreign money sets the market’s direction. Since 2021, DIIs have repeatedly absorbed large FII outflows, and the trend has strengthened into 2026. The article data notes that in H1 2026, FIIs sold aggressively in all six months without a single month of net buying. Against that sustained selling, DIIs absorbed 135% of total outflows on average in H1 2026. That detail matters because it suggests DIIs were not only matching foreign selling but, in aggregate, buying more than the amount being sold by foreign investors. This domestic bid can help reduce the risk of forced, disorderly price discovery during heavy foreign outflows.

H1 2026: Nifty down nearly 9% as pressures built

The first half of calendar year 2026 was challenging for Indian equities. The domestic market faced selling pressure amid heightened geopolitical uncertainty, elevated crude oil prices, and persistent FPI outflows. In this backdrop, the Nifty 50 declined by almost 9% in H1 2026. Even with strong domestic participation, broad indices can still correct when multiple macro factors move against risk assets at the same time. But the presence of consistent domestic buying can affect how the market digests shocks, potentially limiting the depth and speed of drawdowns during extreme foreign selling.

March 2026: a stress test for domestic flows

March stands out as one of the worst months in recent history for foreign selling. FIIs pulled out ₹1,22,540 crore in a single month, according to the data shared. In the same month, DIIs deployed ₹1,42,960 crore. The magnitude is notable because it shows DIIs not only absorbed the selling but also bought more than the FII outflow. This is a concrete example of the broader H1 2026 trend where DIIs, on average, absorbed 135% of total FII outflow. Such episodes also help explain why markets can stabilise even when headlines focus on relentless foreign selling.

2025: heavy foreign selling, yet benchmarks posted gains

Calendar year 2025 captures the two-speed market narrative: foreign investors sold, domestic investors bought, and benchmarks still ended higher. The BSE Sensex and Nifty 50 gained up to about 10% in 2025, marking the tenth consecutive year of positive returns mentioned in the article data. The Sensex rose over 9%, adding 7,080 points from 78,139 (its closing level on December 31, 2024). The Nifty 50 advanced 2,485 points, or 10.5%, from 23,645 over the same period. The year also saw reports of heavy foreign selling and rupee depreciation by year-end, along with muted demand across sectors in the first half of the year that weighed on corporate earnings growth.

How large was 2025 FII selling: multiple estimates, same direction

The dataset includes several figures describing 2025 foreign outflows, reflecting different sources and measurement windows. One data point states FIIs sold approximately ₹170,000 crore in CY2025, while another places the total foreign outflow for 2025 at ₹166,286 crore. A separate figure states FIIs offloaded equities worth ₹144,000 crore in the cash market in 2025. Reuters also described foreign portfolio investors divesting roughly $18 billion worth of Indian shares during 2025, and another line notes foreign investors sold a record $18.5 billion of Indian shares in 2025. Despite the differences in reporting formats, the shared conclusion is that 2025 saw unusually large foreign selling.

Domestic buying in 2025: the key stabiliser

Against the foreign selling, domestic institutional participation remained a major source of support. One part of the data states DIIs infused over ₹700,000 crore into equities during 2025, cushioning the impact of FII outflow. This framing is consistent with the observation that the market’s momentum improved during the closing quarter of the year, supported by robust domestic institutional participation, strong domestic fundamentals, and lower crude prices. The Reuters description also highlights that strong domestic buying mitigated the effects of foreign selling and helped provide stability during volatile periods. Even within FY25’s later phase, DIIs were described as a stabilising counterbalance. October 2024 alone saw DIIs with over ₹100,000 crore in net buying, absorbing a large chunk of selling pressure.

June flows: brief foreign buying returned in equity and debt

The flow picture in 2026 is not one-directional, and the data includes a sharp, near-term turnaround during June. After becoming buyers in Indian debt following tax relief measures and initiatives by the Reserve Bank of India, FIIs stepped up purchases in equities as well. They bought nearly $199 million worth of Indian shares over the last five trading sessions referenced in the text. This renewed foreign interest supported domestic markets, with the Sensex and Nifty gaining nearly 3% each so far in June. Foreign investors also remained active in debt: since June 4, FIIs purchased around $1.68 billion worth of Indian debt. The text describes this as a sharp turnaround from subdued activity earlier in the year.

Why FIIs sold: valuation premium, rupee, yields, and risk

Beyond raw flow numbers, the dataset outlines several reasons attributed to foreign selling behaviour. The narrative argues that FIIs have not “given up on India,” but have become price-sensitive as India’s premium to other emerging markets expanded sharply. It also cites a weaker rupee, high global yields, and mounting geopolitical risks as factors that drove FIIs to book profits and allocate to geographies viewed as more beaten down or offering currency stability. The same narrative suggests foreign interest can return with “valuation sanity,” improved earnings visibility, and a more stable rupee. It also points to selective foreign interest already emerging in industrials, larger financials, and manufacturing plays.

What this means for investors watching H2 2026

The data supports a practical takeaway: domestic flows have become a more durable base for Indian equities, especially during foreign risk-off phases. The H1 2026 example shows that DIIs can materially offset foreign selling, including during extreme months like March. At the same time, the Nifty’s nearly 9% H1 decline shows that domestic support does not guarantee positive returns in difficult macro conditions. The dataset also includes an expectation that India’s improving fundamentals could attract net FII inflows in 2026, but that is framed as a likelihood rather than a certainty. For market participants, the more measurable indicators to track are the direction of FII equity flows, the persistence of DII buying, and the macro drivers cited in the text such as crude prices, geopolitics, currency stability, and global yields.

Conclusion

From 2021 to H1 2026, DIIs have increasingly acted as the market’s stabilising force, repeatedly absorbing FII selling pressure. March 2026, with ₹122,540 crore of FII selling and ₹142,960 crore of DII buying, illustrates how strong domestic flows can counterbalance foreign exits. The flow picture remains dynamic, with June showing renewed FII buying in equities and a sharp pickup in debt purchases. The next key checkpoints will be whether foreign buying sustains beyond short bursts and whether domestic institutions continue to deploy capital at scale during volatility.
