Markets extended their morning losses sharply through the mid-session on Monday, with the BSE Sensex sliding 717.91 points or 0.92 per cent to 77,433.54 and the NSE Nifty50 falling 179.60 points or 0.74 per cent to 24,154.70 as of 12.45 pm, breaching the crucial 24,200 support level that analysts had flagged at the open.The Sensex had closed Friday at 78,151.45 and opened flat at 78,151.45 before the selling gathered pace, while the Nifty had ended the previous session at 24,334.30 and opened at 24,190.05.The carnage was most severe in private sector banking.Axis Bank was the worst performer on the Nifty50, crashing ₹75.60 or 5.69 per cent to ₹1,252.90 on heavy volume of over 1.81 crore shares worth ₹2,29,489.21 lakh, making it the single most actively traded loser by value on the index.HDFC Bank followed, losing ₹42.60 or 5.20 per cent to ₹777.00, with a staggering 3.65 crore shares exchanging hands valued at ₹2,85,859.02 lakh. Kotak Mahindra Bank fell ₹10.20 or 2.62 per cent to ₹379.75, and Jio Financial Services declined 1.96 per cent to ₹238.21.Ponmudi R, CEO of Enrich Money, noted the trigger for the banking sell-off was direct: “...HDFC Bank declining sharply after reporting weaker-than-expected net interest margins, dragging the banking index lower and weighing on broader market sentiment...”Maruti Suzuki joined the losers’ board, dropping ₹393 or 2.85 per cent to ₹13,410, a sign that the selling was broadening beyond financials into consumption and auto sectors.Sudeep Shah, Head of Technical and Derivatives Research at SBI Securities, flagged that the Nifty’s breach of the 24,200 zone had brought the next critical threshold into focus: “...the zone of 24050–24070 will act as a crucial support for the index while the resistance lies in the zone of 24300–24320...” He added that a slip below 24,050 would expose the index to the 23,900–23,920 band.On the options front, Shah pointed to meaningful call writing across the 24,200 and 24,300 strikes, with substantial put open interest at 24,100 and 24,000 strikes, suggesting that the market is pricing in a range-bound to weak bias for the remainder of the session.For Sensex, Shah placed support at 77,200 and resistance at 78,000, levels that traders will watch closely given the index is now trading uncomfortably close to the lower bound.Bank Nifty opened with a sharp gap-down near 57,786, slipping below the 58,000 psychological support. Ponmudi R warned: “...the breakdown below this key level has weakened the near-term technical structure, placing the index under pressure in the opening session...” He identified 57,600–57,500 as the next support, with a break below potentially dragging the index to the 57,300–57,200 zone.Against the broad weakness, select counters held firm. Cipla surged 3.27 per cent to ₹1,465.10 on volume of 8.44 lakh shares worth ₹12,234.07 lakh, extending its morning gains.Trent jumped 2.22 per cent to ₹2,905.60, with over 9.31 lakh shares traded valued at ₹27,083.97 lakh, reflecting buying interest in the consumer and retail space.JSW Steel rose 1.71 per cent to ₹1,258.50, ONGC gained 1.54 per cent to ₹251.09, and Bharti Airtel advanced 1.33 per cent to ₹1,934.10, keeping the telecom sector in positive territory.On the commodity front, crude oil remained a key pressure point. MCX Crude Oil opened with a sharp gap-up, reclaiming levels above ₹8,000 and trading in the ₹8,100–₹8,150 range, driven by the ninth consecutive night of US military strikes on Iran and fears of disruptions to the Strait of Hormuz.US Oil similarly broke above $83 from its prior consolidation zone. Ponmudi R noted that crude hovering “...around the $85 per barrel mark, as fears of prolonged geopolitical tensions and potential supply disruptions continued to underpin energy markets...” was compounding investor caution.The Indian rupee weakened to a two-month low of around ₹96.4 against the US dollar, reflecting dollar demand and crude pressure.On the precious metals front, MCX Gold opened with a gap-up near ₹1,41,500, with resistance at ₹1,42,000, while MCX Silver faced resistance near ₹2,20,000. COMEX Gold continued to hold above the $3,980–$4,000 support zone.Broader market breadth on the BSE presented a more resilient picture. Of 3,551 stocks traded, 1,741 advanced against 1,598 declines, with 212 unchanged. Seventy-two stocks hit fresh 52-week highs against 59 at 52-week lows, while 112 stocks were locked in upper circuits compared to 95 in lower circuits, suggesting that the index-level weakness was concentrated in heavyweight financials rather than being a market-wide rout.Ponmudi R summed up the session’s mood: “...in the absence of any meaningful easing in geopolitical tensions, broader market sentiment is expected to remain cautious, with earnings and global developments continuing to dictate near-term market direction...”Published on July 20, 2026
