The SENSEX fell as much as 1,021 points on Monday, October 19, ending the day at 73,853 after a two‑day winning streak was halted. The NIFTY50 index touched an intraday low of 22,845 and closed at 22,889, a decline of 257 points. The downturn was driven by losses in major banks and corporates, including HDFC Bank, Axis Bank, ICICI Bank, Infosys and Bharti Airtel, as well as Bajaj Finance, Reliance Industries and Hindustan Unilever.

International oil markets influenced domestic sentiment, with Brent crude futures falling 1% yet remaining above $108 per barrel. The price movement followed U.S. President Donald Trump’s waiver of sanctions and tariffs on Russian fuel exports, a decision aimed at easing pressure on Moscow amid the Ukraine conflict. Trump signed an executive order on Friday waiving key sanctions under the Graham Act, a move that analysts say could increase Russian fuel supplies to the United States.

Broad‑based selling was evident across the National Stock Exchange, where all major sector gauges, except the PSU Banks, ended lower. The NIFTY Private Bank index fell 1.85%, while the NIFTY Financial Services, FMCG, IT, Realty, Consumer Durables, Healthcare, Pharma, Metal, Auto and Bank indices dropped between 0.6% and 1.2%. Mid‑cap and small‑cap indices also declined, with NIFTY Midcap 100 down 1.1% and NIFTY Smallcap 100 falling 1%.

Among individual stocks, Ixigo surged up to 15% after reporting a consolidated net profit of ₹61.25 crore for the quarter, reversing a year‑on‑year loss of ₹3.17 crore in the September quarter of FY26. Union Bank shares rose 5.5% following a net profit of ₹5,537 crore in the quarter ended September 2026, a 30% year‑on‑year increase from ₹4,249 crore. Its net interest income rose 20% to ₹10,583 crore.

Axis Bank was the top loser in the NIFTY50, falling 4.2% to ₹1,236. The bank’s net profit narrowly missed the LSEG analyst estimate of ₹7,124 crore, with rising bond yields and rupee volatility weighing on treasury income. Global investment bank Goldman Sachs noted that QFY27 earnings were largely in line with expectations, and the cyclical inflection in core pre‑provisioning operating profit growth remains on track. Other stocks such as Tata Motors PV, Infosys, Bajaj Finance, Apollo Hospitals, Ultratech Cement, HDFC Bank, Trent, Hindustan Unilever, NTPC, Max Healthcare and Nestle India fell between 1.8% and 3.1%.

On the upside, JSW Steel, ONGC, State Bank of India, Larsen & Toubro, Eicher Motors, Adani Ports and Dr Reddy's Labs were notable gainers in the NIFTY50 index. Market breadth was extremely negative, with 2,717 shares ending lower and only 846 closing higher on the NSE. The overall decline reflected cautious sentiment amid rising oil prices and geopolitical developments affecting global commodity markets.
