Stock Market Crash: Why markets are down today; key reasons behind Sensex, Nifty fall

Stock Market Crash: Indian equity markets opened sharply lower on Monday. Benchmark indices Sensex and Nifty fell nearly 2 per cent each. Weak sentiment was driven by a spike in crude oil prices and fading hopes of a US-Iran ceasefire.

The BSE Sensex plunged over 1,600 points to hit a low of 75,939. The NSE Nifty50 fell over 450 points to slip below the 23,600 mark in early trade around 9:20 am.

Volatility surged. India VIX jumped more than 13 per cent to move above 21. This reflects rising nervousness among investors.

Top losers, broader market under pressure

Selling was broad-based. Stocks like InterGlobe Aviation, Asian Paints, Bajaj Finance and Eicher Motors led losses in the Nifty50.

Broader markets underperformed benchmarks. The Nifty MidCap index was down 1.28 per cent, while the Nifty SmallCap index slipped 1.23 per cent.

As per exchange data, among sectors, PSU banks and realty stocks saw the sharpest fall. Pharma stocks showed relative resilience and declined the least.

US-Iran negotiations collapse; geopolitical tensions escalate

Investor confidence took a hit following the breakdown of ceasefire discussions between the US and Iran. The failure to reach an agreement squashed any immediate expectations of a reduction in tensions across West Asia.

Concerns escalated further after reports of a possible US move to blockade the Strait of Hormuz. This is a key global oil supply route. Markets fear that any disruption here could trigger a supply shock.

Uncertainty remains high. Investors are worried that a prolonged conflict could hurt global growth in 2025 and keep markets subdued into 2026.

Trump revives tariff threat on China

Adding to concerns, Donald Trump signalled a fresh tariff threat against China.

He reportedly warned that if China supplies weapons to Iran, it could face tariffs of up to 50 per cent. This has raised fears of renewed trade tensions.

Crude oil jumps above $100

Oil prices surged sharply. Brent crude rose over 8 per cent to near $103 per barrel. US WTI crude also jumped more than 8 per cent to around $105 per barrel.

The rally followed failed peace talks and fears of supply disruption. Elevated crude prices remain a key risk for India, as it increases inflation and widens the current account deficit.

Economists warn that if oil stays elevated for over two months, it could hurt economic growth.

Rupee weakens sharply

The Indian rupee came under pressure. It fell 70 paise to 93.43 against the US dollar. In the previous session, it had closed at 92.73.

A stronger dollar and rising oil prices are weighing on the currency. This combination may trigger foreign capital outflows from equities.

Weak global cues add to pressure

Global markets also remained weak. Asian indices tracked the negative trend.

Japan’s Nikkei and South Korea’s Kospi fell over 1 per cent each. China’s Shanghai Composite declined around half a per cent.

Overall, global risk sentiment remains fragile amid geopolitical tensions and rising commodity prices.
