Equities experienced a downturn during the afternoon session as both primary market gauges dropped more than 1% on Monday. The Sensex slumped nearly 930 points due to a heavy sell-off within private sector banking equities, spearheaded by Axis Bank and HDFC Bank, which pulled the major indices downward. Market participants maintained a cautious stance following the September-quarter financial disclosures from these lending institutions, while elevated crude oil values tied to geopolitical frictions around the Strait of Hormuz amplified anxieties regarding inflation and foreign capital movements.
At 1:24 pm, the BSE Sensex hovered at 73,800.08, registering a decrease of 929.19 points or 1.24%. Simultaneously, the NSE Nifty 50 contracted by 275.05 points, or 1.19%, reaching 22,871.10 by 1:25 pm. This pullback followed a substantial surge across domestic stocks in the preceding week, though Monday's losses indicated lingering apprehension among traders concerning banking sector profitability, high energy costs, and the longevity of overseas capital inflows.
Private sector lenders emerged as primary detractors after market participants evaluated the latest periodic performance reports from key institutions. Axis Bank equity values retreated 4.15%, while HDFC Bank experienced a 2.72% reduction. Additional losses included Yes Bank down 2.63%, Kotak Mahindra Bank declining 1.87%, and Bandhan Bank dropping 1.34%. In the broader market, ICICI Bank recorded a 0.63% dip, Bajaj Finance fell 1.55%, and Bajaj Finserv lost 2.07%.
HDFC Bank documented a 4.7% year-on-year expansion in September-quarter net profit, reaching Rs 19,510 crore. Nevertheless, diminished secondary revenues, elevated operational expenditures, and increased provisions partially counteracted the gains in primary interest income, while its net interest margin compressed from 3.30% in the prior period to 3.16%.
Axis Bank posted a standalone net profit of Rs 7,003 crore, falling slightly short of consensus analyst forecasts projecting Rs 7,124 crore, as higher operational expenses and softer non-interest earnings weighed on market outlook. These reactions underscore the tendency of investors to scrutinize operational margins, overhead costs, treasury returns, and asset health rather than relying solely on headline net profit figures.
Foreign institutional investors participated as net purchasers in the cash segment on Friday, acquiring equities valued at Rs 1,165.92 crore according to official metrics, contrasting with net disposals of Rs 5,285.37 crore on Thursday. Despite this, a single session of net buying fails to confirm a definitive reversal in overseas capital trajectories, as foreign entities have remained consistent net sellers of Indian securities through much of 2026, increasing market susceptibility to shifts in global risk sentiment.
Supplementary data revealed that domestic institutional investors functioned as net sellers totaling Rs 3,661.28 crore on Friday, following acquisitions worth Rs 3,319.39 crore on Thursday. These alternating daily flows highlight ongoing fluctuations in institutional participation, with observers closely monitoring whether overseas purchasing persists in upcoming sessions or if the broader selling pattern resumes.
Petroleum pricing continues to pose a significant risk factor for domestic equities, with Brent crude changing hands at $107.27 per barrel and US West Texas Intermediate resting at $99.58. Intensifying friction near the Strait of Hormuz has generated fears regarding petroleum availability and pricing. Given that the nation procures a substantial portion of its petroleum via imports, prolonged pricing elevation can expand the import expenditure, burden the national currency, and complicate the inflation outlook.
Furthermore, elevated energy costs can compress corporate margins and consumer purchasing power, reinforcing a prudent investment posture alongside existing uncertainties regarding international interest rates and foreign investment flows.
The broader market contraction extended past the primary indices, with the Nifty 100 declining 1.01%, the Nifty 200 down 0.96%, and the Nifty 500 retreating 0.95%. Midcap and smallcap segments followed suit, as the Nifty Midcap 50 dropped 0.68%, the Nifty Midcap 100 fell 0.80%, and the Nifty Smallcap 100 gave up 0.76%.
Sector-specific gauges displayed widespread losses, led by a 1.94% reduction in the Nifty Private Bank index and a 1.45% drop in the Nifty Financial Services 25/50 index. The Nifty FMCG sector fell 1.43% and the Nifty IT index lost 1.54%, alongside downward pressure in realty, consumer durables, and chemical stocks. Conversely, the Nifty PSU Bank index defied the general direction by advancing 2.19%, illustrating a clear divergence between state-backed and private financial institutions. Meanwhile, the India VIX volatility indicator climbed 5.65% to settle at 14.86.
Dr V K Vijayakumar, Chief Investment Strategist at Geojit Investments Limited, observed that momentum derived from the prior week's 2.8% Nifty advance, coupled with favorable outcomes from prominent technology and financial firms, could assist markets in sustaining stability. However, he warned that escalating regional friction near the Strait of Hormuz and Brent crude hovering close to $109 per barrel might serve as formidable obstacles. He noted that attractive valuations among large-cap equities and a firmer currency had encouraged mild optimism among foreign investors toward the country, though high petroleum valuations threaten to obstruct that transition. Vijayakumar anticipates that large-cap companies will maintain their outperformance relative to mid-tier alternatives.
