The equity markets across the globe, including India, saw heavy sell-off on Friday. The Indian benchmark indices – Nifty and the Sensex – ended 3.8 per cent lower. There were two main reasons for this widespread selling: first, US air strike on Syria and, second or the more important, rising US bond yields which shot up to 1.6 per cent. This is for the second time in the week that equity markets have witnessed heavy selling in the wake of rising bond yields.
