India's benchmark equities S&P BSE Sensex and NSE Nifty 50 witnessed sharp selling pressure on Monday, with indices tumbling nearly as escalating tensions in West Asia, a spike in crude oil prices and sector-specific concerns combined to dent investor confidence.

The BSE Sensex fell over 2,700 points to an intraday low of 78,543.73, while the Nifty 50 plunged 2.28% to hit a low of 24603.50 during the day's trade.

The decline was triggered primarily by geopolitical developments in the Middle East and rising crude prices, which have heightened concerns over inflation and India’s external balances.

Oil surge and rupee pressure

Brent crude prices climbed sharply, hovering near the $78–$80 per barrel range amid fears of supply disruptions following intensified hostilities in the region. For India, which imports more than 80% of its crude requirements, sustained elevated oil prices could widen the current account deficit and exert pressure on retail inflation.

The Indian rupee weakened past the 91-per-dollar level during the session, touching record lows. A weaker currency, coupled with higher crude prices, has raised concerns about imported inflation. Market participants also pointed to continued foreign institutional investor (FII) outflows as global capital sought safer assets amid heightened geopolitical uncertainty.

Sectoral weakness led by IT and financials

Selling was pronounced in information technology and banking stocks. The Nifty IT index extended recent losses, reflecting concerns over global demand conditions and valuation pressures after a sharp correction in February. Financial stocks were also under strain, with select mid-sized lenders facing company-specific headwinds.

Shares of Fino Payments Bank remained volatile following developments related to a GST investigation involving its chief executive, while IDFC First Bank continued to see cautious trading sentiment after a recent fraud disclosure. Broader financials tracked the overall market weakness.

All sectors were trading in red on Monday afternoon. Select gainers in today's session include Bharat Electronics, ONGC, Sun Pharma, Hindalco, and Bharti Airtel.

Strong macro data fails to lift mood

The sell-off came despite encouraging domestic macroeconomic data. India reported robust 7.8% GDP growth for the December quarter, and the latest manufacturing PMI reading remained firmly in expansion territory. However, analysts noted that in the current environment, global risk factors are outweighing positive domestic fundamentals.

Technical outlook

Technically, analysts flagged the 24,600 level on the Nifty as an important near-term support. A sustained breach below this zone could open the door for further downside towards the 24,200–24,000 range. With a market holiday scheduled on Tuesday, traders were seen trimming positions to mitigate potential gap risks. 

"The zone of 25,180–25,200 is expected to act as a key resistance area for the index. Until this hurdle is decisively breached, the market is likely to remain in a phase of consolidation with a negative bias. A sustained breakout above 25,200 could trigger further upside momentum, paving the way for a move towards the 25,330–25,350 zone. On the downside, a break below 24,850 may weaken sentiment and drag the index towards the 24,720–24,700 support band," SBI Securities said in a research note.
