Indian equities log eighth consecutive weekly loss, longest streak in 25 years

⚡ Key Financial Takeaways

  • The Sensex dropped 571 points on Oct 1, marking the eighth straight weekly decline – a 25‑year record.
  • FIIs were net sellers of Rs 349.7 bn in the past week, while DIIs bought Rs 334.6 bn.
  • In September, FIIs withdrew Rs 440.1 bn and DIIs added Rs 760.3 bn; FIIs’ FY‑26 outflows total $28.3 bn.
  • Nifty fell 6.1% in September, its second consecutive monthly decline and the steepest since Oct 2024.
  • Higher US Treasury yields, firm Brent crude prices and uncertainty over a possible Iran peace deal are cited as key sentiment drivers.

💡 Why It Matters

The prolonged weekly decline signals a shift in market sentiment, driven largely by foreign capital outflows and global macro risks. Persistent FII selling reduces liquidity and can amplify price volatility, while domestic institutional buying may not be sufficient to offset the pressure. The trend also reflects how external factors—US interest rates, oil prices and geopolitical tensions—are increasingly influencing Indian equity performance, affecting investors, corporates and policy makers alike.

Eight‑week losing streak sets a 25‑year record India’s equity markets have now posted eight straight weeks of losses, the longest such run since 1999. On 1 October the benchmark Sensex slipped 571 points and the Nifty fell 0.88%, extending a four‑day losing streak.

Foreign investors pull out, domestic funds step in Research from Bajaj Broking shows FIIs were net sellers of **Rs 349.7 bn** in the last week, according to provisional exchange data. By contrast, domestic institutional investors (DIIs) were net buyers of **Rs 334.6 bn**.

### September snapshot * FIIs withdrew **Rs 440.1 bn** from Indian equities in September 2026. * DIIs injected **Rs 760.3 bn** during the same month. * In dollar terms, FIIs recorded **$4.1 bn** of outflows in September, taking their calendar‑year total to **$28.3 bn**. DIIs invested **$8 bn** in September and **$67.8 bn** year‑to‑date.

Market backdrop: global and domestic pressures Motilal Oswal notes that the Nifty’s **6.1%** fall in September was the second consecutive monthly decline and the second‑steepest drop since October 2024. The index is down **13.4%** in calendar‑year 2026.

Broad‑based weakness was evident across sectors, with Technology, Financials (excluding banks), Automobiles, PSU Banks and Capital Goods all posting declines in September.

Analysts point to three intertwined factors: 1. **Elevated US Treasury yields** – higher global financing costs dampen risk appetite. 2. **Firm Brent crude prices** – rising oil adds inflationary pressure and hurts the rupee. 3. **Geopolitical uncertainty** – the outlook of a possible Iran peace deal and ongoing US‑Iran tensions keep investors cautious.

Domestic concerns such as a depreciating rupee, lingering inflation and a fragile macro outlook further compound the sentiment challenge.

Outlook Bajaj Broking warns that continued FII outflows, oil price movements and US‑Iran developments will remain the primary drivers of market direction in the near term.

🏛️ Background & Context

India’s equity markets have historically been sensitive to foreign institutional flows. In 2023‑24, FIIs were net buyers, supporting a rally in the Sensex and Nifty. However, a tightening US monetary stance and higher global oil prices have reversed that trend, leading to the current eight‑week losing streak, the longest since the late 1990s.

👁️ What To Watch Next

Investors should monitor: (1) US Treasury yield movements, especially any further hikes; (2) Brent crude price trends; (3) developments in US‑Iran diplomatic talks; (4) RBI’s policy response to a weakening rupee and inflation; and (5) any shift in FII net flow patterns in the coming weeks.
