Oil Shock and Foreign Fund Outflows Drag Sensex Down 548 Points, Nifty Slips Below 22,400

Indian stock markets surrendered their early gains on Monday as rising crude oil prices, persistent foreign investor selling and climbing bond yields triggered fresh concerns over the market outlook.

The BSE Sensex fell 547.65 points, or 0.76 per cent, to close at 71,924.68, after plunging as much as 796.23 points during the session. The NSE Nifty declined 157.10 points, or 0.70 per cent, to settle at 22,363.35.

The sell-off came just a day after a strong rally had lifted investor hopes, highlighting how quickly sentiment can turn when global risks intensify.

The biggest pressure came from crude oil, with Brent crude rising 1.14 per cent to $105.80 a barrel. For India, which relies heavily on imported oil, elevated prices can increase the import bill, put pressure on the rupee and complicate efforts to contain inflation. If sustained, higher energy costs can also squeeze corporate margins and household budgets.

Foreign fund outflows added to the pressure. Foreign Institutional Investors sold equities worth Rs 3,568.90 crore on Friday, according to exchange data, reflecting continued caution amid external uncertainties.

Bond markets also raised concerns, with India's 10-year bond yield climbing to a three-year high. Higher yields can make bonds more attractive relative to equities and increase borrowing costs for businesses and consumers.

Among Sensex constituents, ITC, Tech Mahindra, Hindustan Unilever, Larsen & Toubro, State Bank of India and Tata Consultancy Services were among the major losers. Bharat Electronics, Mahindra & Mahindra, Kotak Mahindra Bank and HCL Technologies bucked the trend.

Asian markets were largely weak, with South Korea's Kospi tumbling 3.65 per cent and Shanghai's SSE Composite also ending lower. Hong Kong's Hang Seng edged higher, while European markets traded in positive territory.

On Friday, the Sensex had surged 879.09 points and the Nifty gained 288.65 points. Monday's reversal underlined the fragile nature of the recovery as investors weighed oil prices, capital flows and global economic uncertainty.
