The Sensex fell more than 900 points in morning trade on September 28 as rising crude oil prices, renewed foreign investor selling and higher US bond yields pressured Indian equities. The Nifty 50 also slipped below 23,000, while the broader market saw widespread selling.
Sensex, Nifty Extend Market Losses
Indian stock markets came under heavy selling pressure on Monday, with the Sensex falling nearly 1,000 points during morning trade. At around 10:40 am, the Sensex was at 72,909.34, down 986 points or 1.33%. The Nifty 50 was trading at 22,835.15, down 305 points or 1.32%.
The decline extended a period of weakness for domestic equities. Both benchmark indices had already recorded their seventh consecutive weekly fall last week. The Sensex had closed Friday at 73,895.74, while the Nifty 50 ended at 23,140.50.
The sell-off was broad based. All 30 Sensex constituents were trading in negative territory in early trade, with financial stocks among the major laggards. Mid-cap and small-cap indices also declined, showing that the pressure was not limited to India’s largest companies.
Crude Oil Crosses $106 as Middle East Tensions Rise
The biggest immediate trigger for the Sensex decline was the sharp rise in crude oil prices. Brent crude gained more than 2% and traded around $106.6 to $107 a barrel, while West Texas Intermediate crude moved close to $94 a barrel.
Oil prices rose as uncertainty surrounding the US-Iran conflict increased concerns about global energy supplies. Markets were also watching developments around the Strait of Hormuz, an important route for international oil shipments.
Reports on Monday said US President Donald Trump had rejected an Iranian proposal involving a ceasefire and the reopening of the Strait of Hormuz. The uncertainty around the conflict increased concerns that disruptions to oil shipments could continue.
For India, movements in crude oil prices have a direct economic impact because the country relies heavily on imported oil. A sustained increase in crude prices can raise the import bill, increase pressure on the rupee and add to inflationary pressures.
Why Rising Oil Prices Matter for Indian Stocks
Higher crude prices can affect companies through several channels. For industries that depend heavily on fuel, transportation or petrochemical inputs, rising energy costs can increase operating expenses.
The wider economy can also feel the impact. A higher oil import bill can increase demand for US dollars, putting pressure on the Indian rupee. A weaker rupee can make imported commodities more expensive and complicate the inflation outlook.
On Monday morning, the rupee weakened by around 14 paise to 95.89 against the US dollar. Market participants were watching the currency closely as crude prices and US Treasury yields remained elevated.
The combination of expensive crude and a weaker rupee therefore became an important concern for investors assessing India’s inflation, corporate earnings and interest-rate environment.
US Bond Yields Add Pressure on Equities
Crude oil was not the only factor weighing on Indian markets. US Treasury yields also moved higher, adding another layer of pressure on risk assets.
The US 10-year Treasury yield moved above 5.2%, while the 30-year yield crossed 5.5%. The two-year Treasury yield also moved above 4.9%. Higher bond yields can make fixed-income assets relatively more attractive while increasing the discount rate used to value future corporate earnings.
For emerging markets such as India, elevated US yields can also affect global capital flows. Investors may reassess allocations toward emerging-market equities when US dollar assets offer higher yields.
This backdrop has become particularly relevant as foreign portfolio investors have returned to selling Indian equities during September.
Foreign Investor Selling Adds to Market Weakness
Foreign investor flows were another source of pressure on Monday. According to provisional exchange data cited in market reports, foreign investors sold Indian equities worth around ₹3,694 crore on Friday.
September has seen a renewed shift in foreign portfolio flows after buying activity in July and August. One market assessment cited by India Today put September equity outflows through exchanges at nearly ₹19,000 crore.
Foreign selling can intensify market declines when it occurs alongside negative global cues, higher bond yields and concerns about commodity prices.
The effect was visible beyond the benchmark indices. The Nifty Smallcap 100 and Nifty Midcap 100 both fell more than 1% during early trade, while several sectoral indices also declined.
Financial Stocks Among Major Market Laggards
Financial stocks were also under pressure during Monday’s sell-off. Bajaj Finance, Kotak Mahindra Bank and HDFC Bank were among the major Sensex decliners, while Bajaj Finserv and ICICI Bank also traded lower.
The weakness in financial stocks follows pressure seen in the sector during the previous week. Investors have been assessing the potential impact of proposed changes related to insurance commission structures and their implications for insurance distribution businesses and other financial companies with exposure to the sector.
With financial companies carrying significant weight in India’s major indices, weakness across the sector can have a substantial effect on benchmark performance.
Nearly ₹6 Lakh Crore Market Value Erased
The sharp decline in equities also translated into a significant fall in the total market capitalisation of BSE-listed companies.
India Today reported that BSE’s total market capitalisation fell from around ₹483.25 lakh crore at the beginning of the session to approximately ₹477.08 lakh crore during early trade, representing a decline of about ₹6.17 lakh crore.
Another market report put the reduction at nearly ₹6 lakh crore as the Sensex and Nifty slipped more than 1%.
The decline also pushed volatility higher. The India VIX, which measures expected market volatility, jumped sharply during morning trading. India Today reported a rise of more than 10% in the index.
What Investors Are Watching Now
The market’s next moves will depend heavily on developments in crude oil, the Middle East conflict, US Treasury yields and foreign investor flows.
A sustained rise in crude prices could continue to put pressure on India’s import bill, inflation and the rupee. At the same time, elevated US yields could keep global financial conditions tight and influence foreign allocations toward emerging markets.
Investors will also track the performance of financial stocks after their recent weakness. Domestic economic data and upcoming corporate developments could provide additional signals on the direction of Indian equities.
For now, Monday’s market decline reflects the combination of several external and domestic pressures rather than a single trigger. The sharp rise in crude oil prices has become the immediate concern, while currency weakness, bond yields and foreign selling have amplified the pressure on Dalal Street.
