On Wednesday, the BSE Sensex and Nifty indices experienced significant gains, with the Sensex rising 3.85% to close at 77,562 and the Nifty increasing 3.78% to 23,997. This marked the best day for both indices in over five years, driven by optimism surrounding a provisional ceasefire between the US and Iran, which has reduced fears of an oil shock. The announcement led to a ₹16 trillion increase in BSE's market capitalization, with all sectoral indices closing in the green. However, analysts caution that the relief may be short-lived, as the ceasefire's conditional nature and ongoing geopolitical tensions could impact market stability. Foreign portfolio investors sold shares worth ₹2,811 crore, while domestic institutional investors bought ₹4,168 crore worth of shares. Global markets also reacted positively, with notable gains across major Asian indices. Despite the drop in oil prices, experts warn that restoring energy supply chains will take time, and inflationary pressures may persist.
