Fresh military exchange between Tehran and Tel Aviv sends shockwaves across global markets; Brent crude surges past $96

Indian equity markets opened the week on a deeply unsettling note Monday as renewed hostilities between Iran and Israel triggered a sharp sell-off across Dalal Street. The BSE Sensex nosedived nearly 900 points in early trade on June 8, while the Nifty 50 slumped 1% to 23,113 — a reflection of the anxiety gripping investors not just in Mumbai but across financial capitals worldwide.

Explosions in Iran Unsettle Markets

The trigger was unmistakable. Israel's military launched fresh attacks on Iran Monday, following a wave of Iranian missiles fired at Israeli territory. Tehran accused Israel of repeatedly violating a ceasefire agreement through its continued strikes on Lebanon. The tit-for-tat exchange shattered whatever fragile calm had held in the region and sent risk assets tumbling globally.

The timing was particularly damaging for markets already on edge. Wall Street had recorded steep losses on Friday, with the Nasdaq shedding over 4% and the Dow Jones declining 1.35%. Asian markets opened Monday in freefall — South Korea's KOSPI crashed 4.49% and Japan's Nikkei fell nearly 3.83%, with Hong Kong's Hang Seng also trading in the red.

Blue Chips Bear the Brunt

On the Sensex, heavyweights including TCS, Eternal, Mahindra & Mahindra, IndiGo, Bajaj Finance and Larsen & Toubro were among the hardest hit. The broad-based selling left few sectors unscathed. On the NSE, Nifty Realty led the losses, tumbling 1.96%, while most other sectoral indices traded in negative territory. The only bright spots were Nifty Pharma, PSU Bank and Healthcare, which managed to hold their ground amid the broader carnage.

Oil Spikes as Peace Deal Hopes Fade

Crude oil markets reacted swiftly. Brent crude surged 3.63% to $96.75 a barrel as traders priced in the risk of a wider Middle East conflict and the potential disruption to regional oil supply routes. West Texas Intermediate rose 3.35% to $93.89. The spike came against the backdrop of already fragile negotiations around a US-Iran peace deal — a process that now faces fresh uncertainty with the resumption of hostilities, despite reported appeals from US President Donald Trump urging restraint.

Rupee Under Pressure

The Indian rupee also felt the heat, dropping 17 paise to 95.35 against the US dollar in early trade — a combination of risk-off sentiment, rising oil import costs, and foreign institutional selling. Data showed foreign institutional investors (FIIs) offloaded domestic equities worth ₹8,776 crore on June 5 alone. Over the last 30 days, FII net outflows have totalled a steep ₹76,006 crore. Domestic institutional investors (DIIs) stepped in to absorb some of the pressure, buying ₹9,134 crore on the same day.

Wider Fallout Being Assessed

Market participants are now closely watching how the situation evolves over the coming hours. Any escalation could push crude further upward, adding to inflationary pressure and widening India's current account deficit. The RBI's room to manoeuvre on rates could also come under scrutiny if the rupee continues to weaken.

For now, Dalal Street is in full risk-off mode. Traders and fund managers will be watching diplomatic developments out of West Asia with as much attention as they give to domestic economic data.
