Sensex opened 364.27 points or 0.46% lower at 77,816.45 on Wednesday, 8 July, while the Nifty50 slipped 139.15 points or 0.57% to 24,259.55, as renewed geopolitical tensions in the Middle East rattled global risk appetite and pushed crude oil sharply higher. The selloff was broad-based, tracking a weak overnight session on Wall Street and subdued sentiment across Asian markets.

Sectors Under Pressure

Nifty Oil & Gas led sectoral losses, declining more than 1% at the open. Nifty Media, Nifty PSU Bank, Nifty Realty, Nifty Cement, Nifty Metal, Nifty Auto, and Nifty FMCG also fell by up to nearly 1%. Among individual Nifty 50 stocks, Shriram Finance, InterGlobe Aviation, Asian Paints, Bajaj Finance, Eicher Motors, Larsen & Toubro, and JSW Steel ranked among the top losers.

Bright Spots: Pharma and IT Hold Firm

Not all sectors were in the red. Nifty Pharma outperformed, rising 0.73%, as defensive positioning drove flows into healthcare stocks. Nifty IT also traded in the green, up 0.25%, suggesting selective risk-on sentiment within technology despite the broader weakness.

What Triggered the Fall

The primary catalyst was a fresh escalation in the Middle East. The US military launched a series of strikes against Iran, with US Central Command (CENTCOM) stating its forces had begun 'a series of powerful strikes to impose high costs on Iran for targeting and attacking commercial shipping.' The action was described as a response to alleged Iranian attacks on three commercial vessels transiting the Strait of Hormuz. The development sent Brent crude surging nearly 3% to $76.39 a barrel, while US West Texas Intermediate (WTI) crude gained more than 3% to $72.72 a barrel — crossing the psychologically significant $75 threshold. For India, a net oil importer, a sustained rise in crude prices compounds both the fiscal deficit and inflationary pressures.

Global Market Snapshot

Asian markets traded mixed. Japan's Nikkei edged lower, while Hong Kong's Hang Seng rose more than 2% and South Korea's KOSPI declined over 1%. The divergence reflected differing exposures to oil prices and US technology stocks, which sold off in the prior session.

Near-Term Outlook

Market analysts flagged a cautious near-term outlook, noting that Nifty faces resistance around the 24,450 level with immediate support at 24,200. A sustained breach below that support, analysts warned, could drag the index toward the key 24,000 mark. With geopolitical uncertainty likely to persist in the short term, crude price trajectory and any further CENTCOM developments will remain the dominant market variables.
