DIIs Are Now the Market's Backbone. But Can Domestic Money Hold the Line Alone?

For decades, the direction of India's equity markets was broadly dictated by foreign portfolio investors. That equation is changing in 2026 — and the shift is happening faster than most market participants expected.

During Q1 of calendar year 2026, domestic institutional investors invested $27.2 billion in equities, supported by steady inflows through systematic investment plans, absorbing nearly 90% of the foreign selling and cushioning the market from sharper declines. FII ownership is now at a two-decade low, falling below DII ownership for the first time in recent history. As of May 15, FIIs have sold Indian equities worth Rs 2.2 lakh crore in 2026 itself.

The numbers from individual sessions underline how dramatic this role reversal has become. On the day FPIs were net sellers of ₹8,827 crore, domestic institutional investors were net buyers of ₹4,700 crore on a net basis — partially cushioning the fall even as benchmark indices remained under pressure.

Market strategists say that strong SIP-led inflows have reduced the market's dependence on foreign capital compared to previous cycles, and that domestic investors should not equate FII selling with weakening fundamentals.

Market participants believe that incremental FII selling is approaching exhaustion and that Indian markets are transitioning toward a more balanced and resilient structure, with the potential for renewed foreign interest in the second half of 2026. A Goldman Sachs report earlier this month stated that the bulk of foreign selling is likely nearing an end after record outflows over the last several months. Goldman Sachs strategists Sunil Koul and Timothy Moe say that the downside risk of incremental foreign selling could be now limited at around $4-5 billion. 

The critical question, however, is whether domestic money alone can prevent deeper corrections if a major global shock — an escalation in West Asia, a Fed policy surprise, or a sharp crude oil spike — triggers simultaneous retail redemptions and FII selling. SIP inflows are structurally sticky, but they are not unconditional. If markets fall hard enough for long enough, even disciplined SIP investors begin to pause contributions, as April 2026 data already hinted. The resilience of DII flows is genuine and historically significant — but it has limits that the market has not yet been forced to test.
