Sensex crashes 1,600 points: Here's what pulling it down

Indian equity markets nose-dived on Wednesday, extending their losses with the sell-off deepening. At 2:13 pm, the BSE Sensex plunged 1,645.88 points, or 2.11 per cent, to 76,534.84, while the NSE Nifty50 slipped below the 23,900 mark.

This came as renewed geopolitical tensions in West Asia took a sharp turn as the US and Iran hit one another’s targets following strikes on commercial ships on Tuesday. The renewed tension flared up further as US President Donald Trump said in Ankara, Turkey, where he is attending the Nato summit, that the “Iran ceasefire was over” for him. He lashed out at the Iranian leadership, calling them “liars,” “cheat” and “sick people”.

The sharp fall in Sensex and Nifty also came with a spike in crude oil prices, and weak global cues, triggering broad-based risk aversion. This reflects widespread selling across sectors amid mounting concerns over the economic fallout from rising oil prices and escalating US-Iran tensions.

Renewed US-Iran tensions rattle investor sentiment

More from Business

The biggest trigger behind Tuesday's market sell-off is the sharp escalation in geopolitical tensions between the United States and Iran. Fresh military action has reignited fears of a wider conflict in the Middle East, prompting investors across global markets to reduce exposure to riskier assets. The uncertainty has sparked a classic risk-off trade, with equities coming under heavy selling pressure.

Crude oil surge raises concerns for India's economy

Brent crude oil prices climbed above $76 per barrel after concerns emerged over potential disruptions to oil supplies from the Middle East. The rally in crude is a major concern for India, which imports nearly 85% of its crude oil requirements. Higher oil prices increase the country's import bill, put pressure on the current account deficit, fuel inflation and raise input costs for companies, weighing on corporate profitability and economic growth.

Weak global cues add to selling pressure

Indian equities also tracked weakness in global markets, where investors turned cautious amid geopolitical uncertainty and renewed selling in technology stocks. The risk-off mood across international markets spilled over to Dalal Street, prompting broad-based selling across sectors.

Profit booking after recent rally

Markets had rallied strongly over the past few weeks, supported by easing crude prices, improving foreign institutional investor (FII) inflows and optimism over June-quarter earnings. The latest geopolitical shock has prompted investors to lock in gains, accelerating the decline in benchmark indices.

Heavyweight stocks drag benchmark indices lower

The sell-off was broad-based, with banking, financial, IT, auto and energy stocks witnessing sharp declines. Selling in heavyweight stocks amplified losses in the Sensex and Nifty, dragging both benchmark indices sharply lower.
