Sensex slides over 1,200 pts from day high as oil spike triggers market reversal

Indian equities reversed early morning gains on Friday, as an abrupt surge in international crude oil prices rattled trading desks across Asia and triggered heavy profit-taking on Dalal Street.

The BSE Sensex climbed 517 points in early trade to reach an intraday peak of 73,766.51 before swinging sharply into negative territory. At its lowest point of the session, the benchmark index touched 72,487.47 — a plunge of 1,279 points from its morning high — before trading down around 630 points near 72,600. The broader NSE Nifty 50 tracked a matching arc, rising to an early peak of 22,787.25 before tumbling 380 points to touch an intraday low of 22,407.05.

The midday downturn wiped nearly ₹10 lakh crore off the combined market capitalisation of BSE-listed firms, dragging total market valuation below ₹4.49 lakh crore.

Global energy pressures test market nerves

The immediate trigger came from international energy markets, where Brent crude spiked towards $114 per barrel following fresh conflict in West Asia and reported Houthi strikes on oil infrastructure in Saudi Arabia. Because India imports over four-fifths of its crude requirements, sharp escalations in energy costs routinely spark near-term nervousness regarding imported inflation and corporate input margins.

Foreign institutional investors (FIIs) offloaded equities worth ₹3,458.70 crore on Thursday, maintaining net selling in 11 out of 14 sessions in October. Friday's risk-off sentiment echoed throughout Asian markets, with Tokyo's Nikkei 225 slipping 1.7% and Seoul's Kospi shedding 2.4% after an overnight technology rout on Wall Street.

Sector performance and broader markets

While information technology shares offered early support on the back of bargain buying, selling pressure accelerated across rate-sensitive and industrial segments. Broader indices absorbed the bulk of the decline, reflecting a routine valuation reset away from heavily priced smaller counters towards established large caps.

Among individual shares, Tata Consultancy Services gained more than 3% in early trade, while Reliance Industries and ICICI Bank showed notable resilience. Conversely, companies such as Tata Steel, Titan, Adani Ports, and Bharat Electronics shed between 2% and 4%.

Underlying domestic strength

Despite the external headwinds, market strategists note that India's domestic economic architecture remains far better positioned to absorb global turbulence than in past cycles. Domestic institutional investors (DIIs) stepped in with ₹2,891.32 crore in purchases on Thursday alone, counterbalancing overseas outflows.

Moreover, macro stability indicators provided quiet support under the surface. The rupee held steady around 94.70 to the US dollar, and US 10-year Treasury yields eased back to 4.96%. Analysts at Geojit Investments pointed out that more than ₹3 lakh crore in capital locked up during recent primary market subscription windows, including the mega Jio Platforms IPO, will re-enter the banking system by Monday.

That anticipated domestic liquidity release, combined with sound balance sheets across corporate India, is expected to provide substantial buying support for high-quality large-cap equities once short-term crude volatility stabilises.
