FIIs vs DIIs, Reversing Roles After 25 Years
Why in News?
The Indian equity market has witnessed a dramatic shift in the balance of power between Foreign Institutional Investors (FIIs) and Domestic Institutional Investors (DIIs). Once dominated by foreign flows, the market is now increasingly driven by domestic money, reversing the trend observed over the last 25 years. Recent data shows that DIIs have overtaken FIIs in terms of outstanding equity investments, signaling a structural transformation in India’s financial landscape.
Introduction
Foreign Institutional Investors (FIIs) were first allowed to participate in the Indian stock market in 1992, a landmark reform aimed at integrating India into global capital markets. Their entry was modest, beginning with an investment of just ₹13 crore in 1992-93. On the other hand, Domestic Institutional Investors (DIIs), including entities such as the Unit Trust of India (UTI), bank-sponsored mutual funds, and insurance companies, already had a well-established presence.
For decades, FIIs dominated market movements due to their ability to deploy large sums swiftly. However, in recent years, DIIs have emerged as the dominant force, providing resilience and stability to Indian markets, especially in times of global volatility. The reversal of roles between FIIs and DIIs raises important questions about the future of India’s capital markets, investor confidence, and the global positioning of India as an investment destination.
Historical Background
The Early Phase: FIIs Take the Lead (1992–2000)
When FIIs entered in 1992, the Indian equity market was relatively underdeveloped and starved of liquidity. By 1993, the combined outstanding investments of DIIs stood at around ₹45,000 crore, while FIIs were still in their infancy.
However, problems soon plagued the domestic market. The Unit Trust of India (UTI), which was the largest mutual fund, ran into trouble in the late 1990s due to issues with its assured-return schemes. This shook public confidence in mutual funds, leading to slower mobilisation of household savings. By March 2000, DIIs’ outstanding investments had risen only marginally from ₹65,300 crore in 1998 to ₹65,800 crore.
In contrast, FIIs aggressively expanded their presence. Their investments more than doubled during this period, rising from ₹33,400 crore in 1998 to ₹70,300 crore by March 2000. For the first time, FIIs overtook DIIs in terms of equity investments, establishing their dominance for the next two decades.
The Middle Years: FIIs Dominate, DIIs Struggle (2000–2014)
Between 2000 and 2014, FIIs maintained their lead. Their investments grew at an annual rate of 18%, reaching over ₹6.6 trillion by March 2014. FIIs became the key drivers of market sentiment, often dictating the direction of the Sensex and Nifty.
DIIs, meanwhile, stagnated. Their outstanding investments stood at just ₹4.2 trillion in 2014, significantly lower than FIIs. In fact, DIIs registered a negative growth rate of 2% over this period, primarily because household investors continued to prefer physical assets such as gold and real estate over financial instruments.
Turning Point: DIIs Reclaim Ground (2014–2025)
The real shift occurred after 2014-15. In this period, DII investments in equities surged by 98% and continued to expand strongly. From 2014-15 to 2019-20, DII investments grew at an impressive rate of 55.4%, compared to just 4.9% growth in FII investments.
Post the Covid-19 pandemic, domestic inflows strengthened further. From 2021-22 to 2024-25, DIIs maintained robust inflows, growing by 37% and reaching an all-time high of ₹14 trillion by March 2025. In contrast, FII investments stagnated, amounting to only ₹10 trillion—about 29% lower than DII investments.
This reversal has made DIIs the dominant force in the Indian equity market after 25 years of playing second fiddle.
Key Issues and Institutional Concerns
1. Weakening FII Influence
The co-movement between FII flows and the Sensex was once strong (0.37 between 2000 and 2014). However, in the past decade, this correlation has fallen sharply to -0.03. This implies that FIIs have had virtually no impact on market direction over the last 10 years.
In contrast, the correlation between DIIs and the Sensex rose from -0.20 in 2000–2014 to 0.59 in 2014–2025, underscoring the dominant role of domestic investors.
2. Rise of Retail Participation
A significant factor behind the rise of DIIs has been the steady increase in retail participation. With improved financial literacy, better digital platforms, and systematic investment plans (SIPs), household savings have increasingly moved into mutual funds and equities.
By 2019-20, household savings in capital market instruments stood at over 6% of GDP, comparable to the pre-Covid period, and much higher than two decades ago.
3. Resilience in Times of Global Volatility
DIIs have acted as shock absorbers during periods of heavy FII outflows, such as during the Covid-19 crisis and recent global interest rate hikes. Their consistent inflows have stabilized markets, reducing dependence on volatile foreign capital.
4. Structural Shifts in Indian Economy
The increasing depth of domestic capital markets reflects broader structural changes—growth in the middle class, rising disposable incomes, and greater trust in financial products. This has made India’s markets more self-reliant.
Challenges and the Way Forward
Despite the positive trends, several challenges remain:
-
Low Penetration Beyond Metros – While tier-II and tier-III cities have seen growth in mutual fund penetration, the overall investor base remains narrow compared to developed economies. Expanding retail participation further is crucial.
-
Sustainability of Flows – DIIs have benefited from strong SIP inflows. However, any slowdown in household income growth or financial stress could impact these flows.
-
Valuation Concerns – Indian equities are currently trading at high valuations, with the average price-to-earnings ratio rising from 18.5 (2000–2014) to 23.7 (2015–2025). This raises concerns about sustainability and the possibility of corrections.
-
Uncertain FII Behaviour – While FIIs have slowed in the past decade, they retain the flexibility to re-enter in a big way if global conditions change. This unpredictability remains a factor for policymakers.
-
Need for Deeper Bond Markets – Overdependence on equity investments by DIIs highlights the need to diversify into debt markets, infrastructure bonds, and other long-term instruments.
Conclusion
The Indian equity market has undergone a remarkable transformation over the last 25 years. From being heavily dependent on FIIs, the market is now driven by domestic flows, reflecting rising financial maturity among Indian households and institutions. DIIs have emerged as a stabilizing force, cushioning the market against global shocks and reducing vulnerability to foreign capital flight.
However, this shift also raises new questions: Why have FIIs slowed so sharply in the past decade? Will they return as aggressively as in the 1990s and 2000s? Can DIIs sustain their dominance in the long run?
What is clear is that India’s equity market is entering a new phase of resilience and self-reliance, powered by domestic savings. The next decade will determine whether this transformation is permanent or whether FIIs will reclaim their old role.
