NEW DELHI — Indian equity markets experienced heightened volatility this week as Foreign Institutional Investors (FIIs) reverted to net sellers, offloading equities worth ₹1,602 crore. In sharp contrast, Domestic Institutional Investors (DIIs) maintained an uninterrupted buying spree, injecting ₹17,320 crore across all five trading sessions to absorb foreign capital outflows and stabilize benchmark indices.

The sudden shift in foreign capital flows snapped a three-week streak of net FII buying. Market analysts noted that institutional activity displayed severe intra-week whipsaws, driven by rising crude oil prices hovering above $92 per barrel and escalating geopolitical tensions between the United States and Iran.

Market Performance: Nifty Retains 24,200 Support

The benchmark Nifty 50 traded within a narrow range with a corrective bias, starting the trading week on a weak note and touching an intra-week low of 24,026. A late-week short-covering rally in domestic financial and automobile counters helped the index recover from weekly lows, settling at 24,252—down 0.5 percent on a weekly closing basis.

While large-cap stocks faced selling pressure from global funds, broader markets demonstrated resilience. The Nifty Midcap 100 index closed flat, whereas the Nifty Smallcap 100 index outperformed significantly, surging over 1 percent to hit a fresh all-time high.

Institutional Flow Dynamics and Macro Outlook

An analysis of monthly institutional trends reveals a growing divergence between domestic retail-backed liquidity and foreign capital movement. Despite the weekly net sale, FIIs remain net buyers for August 2026 so far, with an aggregate purchase of ₹2,510 crore. DIIs, supported by robust Systematic Investment Plan (SIP) inflows from retail investors, have accumulated ₹34,370 crore month-to-date.

Over the broader 30-day window from July 20 to August 21, cumulative FII purchases stand at ₹1,282 crore, while DII allocations total an impressive ₹48,390 crore.

Market strategists indicate that near-term market direction will be dictated by energy markets and global macroeconomic signals. With Brent crude maintaining elevated levels above $92, concerns regarding imported inflation and fiscal deficit pressures continue to cap upside momentum for Indian equities. Traders and institutional desk managers are expected to closely monitor diplomatic developments in West Asia alongside foreign exchange fluctuations ahead of the upcoming monthly derivatives expiry.
