Sensex plunged over 900 points intraday on Friday, wiping out about ₹6 lakh crore in investor wealth as the market capitalisation of BSE-listed firms fell from nearly ₹477 lakh crore to ₹471 lakh crore. The selloff was driven by surging crude oil prices, rising US bond yields, and fresh 10% US tariffs on Indian exports announced by President Donald Trump.
