Indian markets gained sharply on Monday after early signs of easing geopolitical tensions in West Asia lifted investor sentiment, though analysts cautioned that the upside may remain measured.

A preliminary understanding between the US and Iran to reopen the Strait of Hormuz and extend a fragile ceasefire triggered a broad-based rally across Indian assets. Benchmark indices surged nearly 1 per cent, with the BSE Sensex rising 736 points to close at 76,264.33 and the Nifty 50 advancing 231 points to 23,853, although resistance near the 24,000-mark limited further gains.

The market rally translated into a sharp increase in investor wealth, as the total market capitalisation of BSE-listed firms jumped by ₹8.5 lakh crore to ₹470.5 lakh crore. Last two sessions, investor wealth has jumped over Rs 18 lakh crore.

Crude oil falls; rupee up

“Ships of the World, start your engines. Let the oil flow!” Trump wrote on ‘X’. Oil prices fell on the news. Brent crude futures fell over 5 per cent to trade around $83 per barrel, its lowest level in nearly two month. For India, a major oil importer, this decline is particularly beneficial as it reduces inflationary pressures, supports the rupee, and improves fiscal stability. Reflecting this, the rupee appreciated by 40 paise to 94.71 against the US dollar. Meanwhile, global safe-haven assets gained ground, with gold rising over 3 per cent and silver climbing over 5 per cent.

India VIX, the market’s volatility gauge, came back close to pre-conflict levels of around 14, reflecting easing investor anxiety as the geopolitical risk premium receded. The US President made the announcement on Sunday evening, with the the peace agreement to be signed on June 19 in Switzerland.

Prime Minister Narendra Modi welcomed the development, posting on social media platform ‘X’ (erstwhile Twitter), said, “I welcome the understanding reached between the United States and Iran on ending the conflict in West Asia, which has caused serious economic disruption across the world and led to loss of life in many countries.”

He added that India hopes that the implementation of this understanding will help restore peace and stability in the region and ensure the freedom of navigation and commerce. He said India looks forward to deliberations on the remaining issues reaching a sustainable final agreement.

Commerce Secretary Rajesh Agrawal added a cautious note, “Many of our problems will be alleviated, in case it is a sustainable deal...If peace lasts and prevails and there is free movement in Strait of Hormuz, it will have a positive impact on trade. But let us wait and see.”

For India, the conflict in West Asia is predominantly viewed as an “energy crisis,” said Trideep Bhattacharya, President and CIO – Equities, Edelweiss Mutual Fund. “We’re optimistic that a US-Iran deal could remove a fiscal drag of roughly 0.5-0.8 per cent of India’s GDP by lowering oil prices.”

Rajesh Palviya, Head of Research at Axis Direct, said the easing of geopolitical tensions following the US-Iran peace agreement opens doors for global risk assets. “The immediate correction in crude oil prices is particularly encouraging for an import-dependent economy like India, as it helps alleviate inflationary pressures, improves macroeconomic stability, and provides greater policy flexibility,” he said.

FII inflows

This could also bring in a sustained revival in foreign institutional investor (FII) inflows, which could act as the next catalyst for the market, Palviya said. On Monday, FPI for the first time in 11 sessions were net buyers to the tune of ₹200 crore.

Market participants, however, remain guarded. While the deal removes a key downside risk – high crude prices that fuel inflation and currency pressure – other factors such as monsoon uncertainty and disruptions in IT hiring linked to artificial intelligence continue to cap aggressive upside.

Focus now shifts to the US Fed’s June 16-17 meeting, where a hawkish stance could curb liquidity and risk appetite. Going ahead, markets will track domestic factors like earnings, monsoon progress, and capital flows, while developments in West Asia will remain a key risk.
