Foreign portfolio investors (FPIs) stepped up their exit from Indian government bonds in September as surging US Treasury yields and geopolitical uncertainty eroded the relative appeal of domestic debt. FPIs sold a net Rs 10,602 crore of government securities under the fully accessible route (FAR) during September, the highest outflow in six months, data from the Clearing Corporation of India showed. This compares with net selling of just Rs 846 crore in August and marks a reversal after four months of strong buying following the government’s tax concessions for overseas investors.
