Net sales of Indian bonds by overseas investors surged the highest in April since the inclusion of local debt on global bond indices, reflecting the undiminished allure of higher returns in the US, and the impact of escalating tensions with Pakistan toward the latter half of the month, market experts said. Reversing four months of inflows, April saw a net 13,359 crore of outflow from the index-eligible fully accessible route (FAR) government securities, the highest monthly exit since India's inclusion in the JP Morgan EM index in July 2024, CCIL data showed. Passive investments often closely track the weightings on global gauges.
