Editorial Analysis
Why This Matters
September's decline matters because **oil prices, foreign investor selling, global interest rates and rupee pressure** affected Indian equities at the same time. The Nifty and Sensex ended the month significantly below their August levels, making the **overall September performance more important than any single trading session**. The next focus will be whether these pressures ease or continue into October.
The Nifty's September decline made it the weakest September performance since 2018, when the index fell 6.42%.
Several factors contributed to the weakness.
Foreign Investor Selling
Foreign investors remained a major source of pressure on Indian equities. Reuters reported that foreign investors pulled approximately $2.7 billion from Indian equities during September, taking their 2026 outflows to about $26.8 billion.
Large foreign outflows can put pressure on heavily traded large-cap stocks and influence overall market liquidity.
Crude Oil and Global Rates
Crude oil remained an important concern for Indian markets because India is heavily dependent on imported oil.
Higher oil prices can increase the import bill and affect inflation and currency expectations. During September, global oil prices were also influenced by geopolitical developments in the Middle East.
At the same time, higher global interest rates and bond yields made emerging-market assets less attractive to some international investors. The US Federal Reserve and several other major central banks raised rates during September, adding to the global financial pressure.
Rupee Pressure
The Indian rupee also remained under pressure during the month.
Reuters reported that the rupee declined about 0.7% in September and around 1.2% during the July-September quarter, with crude oil prices and rising global bond yields contributing to the pressure.
A weaker rupee can increase the domestic cost of imported commodities such as crude oil, although currency movements affect individual companies differently depending on their export and import exposure.
Sector Performance
The September decline was broad-based.
Reuters reported that all 16 major sectors declined during the month, with the IT sector among the weakest, falling about 11.2%. Mid-cap and small-cap indices also declined, by approximately 7.6% and 3.4%, respectively.
Business Standard reported that 40 of the 50 Nifty constituents were lower through September 29, highlighting the breadth of the market weakness.
The final September session also showed differences between sectors. Banking stocks provided some support, while parts of the healthcare, pharmaceutical and metal segments faced selling pressure.
What Happened in the Final Session?
The September 30 trading session ended lower, although the movement remained relatively limited compared with some of the sharper declines seen earlier in the month.

September Market Comparison
The September decline becomes clearer when the two benchmark indices are compared with their August-end levels.
Nifty 50
- August 31 Close: 24,080.40
- September 30 Close: 22,620.45
- September Change: About -6.1%
Sensex
- August 31 Close: 76,957.27
- September 30 Close: 72,480.29
- September Change: About -5.8%
The comparison shows that both major Indian benchmarks ended September substantially below their August-end levels.
The Nifty's approximately 6.1% monthly decline made September its weakest September since 2018.
