Indian Stock Market Today: Nifty Ends September With Sharp Losses as Rupee Slips Below 96
India’s equity market remained volatile on September 29 as investors navigated monthly expiry, rising crude oil prices, a weaker rupee and continued selling pressure across several major sectors.
The Nifty 50 struggled to hold higher levels during the session, while the Sensex remained under pressure. The broader market also stayed weak, with both mid-cap and small-cap stocks extending their recent declines.
The session came at the end of a difficult September series for Indian equities. The Nifty recorded a decline of around 6% during the September series, making it the index’s weakest September series in 25 years, according to the Moneycontrol report.
Nifty Struggles on Monthly Expiry
Trading remained choppy as the Nifty moved away from the day’s high and slipped below the 22,700 level during the session. The Sensex was also down around 300 points at one stage.
Monthly expiry can naturally increase volatility because traders adjust or close derivative positions. However, the weakness this time came against a broader backdrop of pressure on Indian equities.
Recent market declines have been accompanied by concerns over crude oil, global bond yields, geopolitical uncertainty and foreign investor selling. Reuters reported that the Nifty was trading near six-month lows during Tuesday’s session, while Brent crude remained around the $105-a-barrel area.
September Becomes a Difficult Month for the Nifty
The biggest takeaway from the September series is the breadth of the decline.
The Nifty fell approximately 6% during the month, while almost every major sector ended the series lower. Pharma was the notable exception highlighted in the Moneycontrol report.
This matters because a broad market decline generally indicates that weakness is not limited to one particular industry.
Auto, realty and PSU banking stocks were among the sectors that performed particularly poorly during the September series. Meanwhile, the small-cap and mid-cap indices ended their five-series winning streaks.
For investors, the shift in broader-market momentum is an important development. Small- and mid-cap shares had previously benefited from strong investor participation, but the recent selling suggests that risk appetite has weakened.
IT and Consumer Durables Remain Under Pressure
IT stocks continued to face selling pressure during the session. Consumer durable companies were also among the weaker areas of the market.
The pressure on technology stocks has been particularly visible in recent sessions, with the Nifty IT index experiencing a prolonged decline.
A combination of global technology-sector sentiment, currency movements, valuation concerns and uncertainty surrounding future earnings can influence the performance of Indian IT companies.
Consumer-facing companies, meanwhile, can be sensitive to changes in input costs and household spending conditions.
Metal and Pharma Stocks Show Relative Strength
Not every part of the market moved lower.
Metal and pharmaceutical stocks showed relative strength, providing some support while several other sectors declined.
Among the Nifty 50 constituents highlighted in the Moneycontrol report, Dr Reddy’s Laboratories, Kotak Mahindra Bank and Tata Steel were among the leading gainers. Titan, HCL Technologies and HDFC Life were among the notable laggards.
The divergence between sectors shows why looking only at the headline index can sometimes hide important market trends.
Rupee Falls Below the 96-per-Dollar Level
The currency market added another layer of uncertainty.
The Indian rupee breached the ₹96-per-dollar mark and reached a two-month low on September 29. Reuters reported that the rupee traded around 96.1450 per US dollar, while rising crude prices increased pressure on the currency.
The relationship between crude oil and the rupee is particularly important for India because the country depends heavily on imported crude.
When oil prices rise sharply, the country's import bill can increase. If the dollar also strengthens, pressure on the rupee can become more pronounced.
A weaker rupee can benefit some exporters because foreign-currency revenues translate into more rupees. However, it can also increase the domestic cost of imported commodities, equipment and certain raw materials.
Why Oil Prices Matter for Indian Markets
The rise in crude oil has become one of the major factors influencing investor sentiment.
Reuters reported that Brent crude moved above $107 a barrel on September 29 amid supply concerns linked to the continuing US-Iran conflict.
For India, expensive oil can create several potential pressures at the same time.
Higher crude prices can increase import costs, put pressure on the current account and contribute to inflation concerns. Companies with high energy or transportation costs may also face pressure on margins if they cannot fully pass higher costs to customers.
This explains why movements in crude oil are increasingly important for investors watching Indian equities.
Foreign Selling Adds to Market Pressure
Foreign investor activity has also been an important factor behind the recent weakness.
Reuters reported that foreign investors had withdrawn about $3.7 billion from Indian equities in September as market pressures intensified.
Large foreign outflows can affect both equity prices and the currency because investors selling Indian assets may convert rupees back into dollars.
That creates a link between equity-market weakness and rupee depreciation: selling in stocks can increase currency pressure, while a weaker rupee can in turn influence investor sentiment.
What the September Sell-Off Tells Investors
The September decline highlights how quickly market leadership can change.
For much of the previous period, small- and mid-cap stocks had enjoyed strong momentum. Their current decline suggests investors are becoming more selective and, in some cases, reducing exposure to higher-risk segments.
At the same time, the fact that pharma and selected individual stocks continued to perform relatively well shows that the market is not moving uniformly.
This makes sector-level analysis increasingly important.
Key Factors to Watch Going Forward
The September series leaves investors with several important indicators to monitor:
Crude oil: Sustained prices above recent levels could continue to influence inflation expectations, corporate costs and the rupee.
Rupee movement: A sustained move beyond ₹96 per dollar could remain an important market variable.
Foreign investor flows: Continued overseas selling could keep pressure on large-cap equities.
US bond yields: Higher global yields can make emerging-market assets relatively less attractive and affect capital flows.
IT earnings: Investors will watch whether the prolonged weakness in technology stocks starts to reflect changing expectations for earnings.
Small- and mid-cap stocks: The end of their five-series winning streak makes market breadth an important indicator for the next phase.
Market Outlook After a Weak September
September's decline does not by itself determine what the market will do next. Instead, the key question is whether the factors behind the sell-off begin to ease.
A moderation in crude prices, stabilization in the rupee, improving global risk sentiment or a reduction in foreign selling could change the market environment. On the other hand, continued geopolitical uncertainty, elevated oil prices and high global yields could keep volatility elevated.
For investors, the September performance therefore provides an important reminder that index movements can be driven by several interconnected factors rather than by domestic company fundamentals alone.
The next market phase will likely depend on how these external pressures interact with corporate earnings, valuations and domestic liquidity.
