Mumbai, May 11 (PTI) Stock markets fell for the third day running on Monday, with the benchmark Sensex tumbling 1,313 points amid rising crude oil prices after the US and Iran failed to reach a peace deal to end the war in West Asia.

The 30-share BSE Sensex tanked 1,312.91 points, or 1.70 per cent, to settle at 76,015.28. During the day, it tumbled 1,370.79 points or 1.77 per cent to 75,957.40.

The 50-share NSE Nifty dropped 360.30 points or 1.49 per cent to end at 23,815.85. In three sessions since Thursday, Nifty dropped over 2 per cent or 515 points, while Sensex has fallen by nearly 1,950 points or 2.5 per cent.

US President Donald Trump dismissed Iran's response to the latest peace proposal as 'totally unacceptable', dampening hopes of an immediate diplomatic breakthrough, an expert said. Also, Prime Minister Narendra Modi’s appeal for austerity measures amplified investor concerns around forex reserves, fuel costs, and consumption outlook, analysts said.

Among the 30 Sensex firms, Titan was the biggest loser, dropping by nearly 7 per cent. InterGlobe Aviation, State Bank of India, Bharti Airtel, Eternal and Reliance Industries were among the major laggards.

Sun Pharma, Hindustan Unilever, Adani Ports, Kotak Mahindra Bank, Axis Bank and ICICI Bank were the winners.

Brent crude, the global oil benchmark, traded 2.23 per cent higher at USD 103.5 per barrel.

"The Indian equity markets witnessed a sharp sell-off session today, with benchmark indices correcting more than 1.4 per cent amid rising geopolitical concerns and heightened fears over inflationary pressures.

"Rising uncertainty surrounding crude oil prices and fears of further geopolitical escalation triggered aggressive unwinding of positions, dragging indices lower into the close," Hariprasad K, Research Analyst and Founder, Livelong Wealth, said.

The immediate trigger for today’s weakness came after Prime Minister Narendra Modi’s speech on May 10, which the market interpreted as a sign of mounting macroeconomic stress, he said.

"While global uncertainty surrounding the US-Iran conflict and surging crude oil prices had already weakened sentiment, the Prime Minister’s appeal for austerity measures amplified investor concerns around India’s forex reserves, fuel costs, and consumption outlook," Hariprasad added.

Emphasising that the Centre is trying to shield people from the adverse impact of the conflict in West Asia, Prime Minister Narendra Modi on Sunday called for judicious use of fuel, postponement of gold purchases and foreign travel, among other measures, to strengthen the economy.

Addressing a rally organised by the Telangana BJP in Hyderabad, he suggested reducing petrol and diesel consumption, using metro rail services in cities, carpooling, increased use of electric vehicles (EVs), utilising railway services for parcel movement, and working from home to conserve foreign exchange amid the crisis in West Asia.

Stressing the need to conserve foreign exchange amid the crisis, Modi called for postponing gold purchases and foreign travel for one year.

"We have to save foreign exchange by any means," he said, adding that due to the West Asia conflict, prices of petrol and fertilisers had increased significantly.

In Asian markets, Japan's benchmark Nikkei 225 index ended lower, while South Korea's benchmark Kospi and Shanghai's SSE Composite index and Hong Kong's Hang Seng index settled higher.

Markets in Europe were trading mostly lower.

US markets ended higher on Friday.

"The benchmark index slipped below the 24,000 mark as renewed Gulf tensions, following Trump’s rejection of Iran’s peace proposal, weighed on investor sentiment.

"The cautious mood deepened after the PM’s appeal to conserve energy and avoid non-essential foreign travel, prompting investors to reassess the economic impact of higher crude prices, INR weakness, and pressure on the current account deficit," Vinod Nair, Head of Research, Geojit Investments Limited, said.

Foreign Institutional Investors (FIIs) offloaded equities worth Rs 4,110.60 crore on Friday, according to exchange data.

On Friday, the Sensex tanked 516.33 points or 0.66 per cent to settle at 77,328.19. The Nifty dropped 150.50 points or 0.62 per cent to end at 24,176.15. PTI SUM SUM MR

Crude oil price shock and austerity appeal weigh on investor sentiment amid foreign exchange and inflation concerns. Stock market weakness was linked to rising crude oil prices, renewed geopolitical tension in West Asia, and concern over inflationary pressure, fuel costs, foreign exchange reserves, and the current account outlook. Investor sentiment was further affected by the Prime Minister's appeal for austerity and conservation of foreign exchange through reduced fuel use, postponement of gold purchases and foreign travel, greater use of public transport, carpooling, electric vehicles, rail services, and work from home.
