"The Indian equity markets witnessed a sharp sell-off session today, with benchmark indices correcting more than 1.4% 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," Mr. 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 (May 10, 2026) 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, Mr. 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.
