Indian equity benchmarks closed sharply lower on Monday, with the BSE Sensex ending 1,312.91 points or 1.70% down at 76,015.28 and the NSE Nifty 50 falling 360.30 points or 1.49% to close at 23,815.85 — the index's steepest single-session decline in over a month. Two developments over the weekend drove the sell-off: a breakdown in US-Iran peace negotiations that pushed crude oil to multi-month highs, and Prime Minister Narendra Modi's public appeal asking citizens to voluntarily reduce consumption of gold, petrol, diesel, and foreign travel.

US-Iran talks collapse, oil spikes

Diplomatic efforts to de-escalate the West Asia conflict hit a wall over the weekend. The US had submitted a fresh peace proposal to Iran, which Tehran rejected, calling it a "surrender demand." Iran countered with its own set of conditions — including war reparations, full control over the Strait of Hormuz, and the lifting of all sanctions. President Donald Trump responded on Sunday, saying Iran's reply was "totally unacceptable." Iran, in turn, said it would "never yield." With the Strait of Hormuz remaining partially blockaded and no resolution in sight, Brent crude climbed to $106.30 a barrel and WTI rose to near $100 — levels that directly strain India's import bill and current account position.

Modi's appeal rattles consumer stocks

Prime Minister Narendra Modi, addressing a public rally in Hyderabad on Sunday evening, urged Indians to avoid buying gold jewellery for at least one year and to cut back on non-essential foreign travel. "For the nation, we must decide that for one year, we will not buy gold jewellery at any function or event. To save foreign currency, our patriotism is being challenged," he said. Markets interpreted the remarks as a signal that the government is concerned about pressure on India's foreign exchange reserves and the rupee.

Jewellery and aviation stocks hit hard

Titan Company was the biggest loser on the Nifty, falling 6.85% to ₹4,200 — despite having reported a strong Q4 earnings beat last week. Kalyan Jewellers dropped over 7%, Senco Gold fell nearly 9%, and Sky Gold tumbled around 11%. The Nifty Consumer Durables index fell 3.73%, the sharpest sectoral decline of the session. IndiGo fell 4.73% as the PM's foreign travel remarks dampened sentiment on aviation stocks. SpiceJet and GMR Airports also ended lower.

Broad-based selling across sectors

SBI fell 4.36%, Eternal dropped 4.03%, Jio Financial Services slid 3.81%, Bharti Airtel lost 3.79%, and Reliance Industries declined 3.48%. Nifty PSU Bank fell 2.52%, Nifty Realty dropped 3.05%, Nifty Auto slipped 1.86%, and Nifty Oil & Gas declined 2.24%. Pharma, healthcare, and FMCG indices ended marginally in the green, reflecting a defensive tilt among investors. Tata Consumer Products was the standout gainer on the Nifty, rising 8.05% on the back of strong quarterly results.
