Mumbai: Market regulator Sebi said long -term FPIs such as sovereign wealth and foreign central bank can invest in government bonds having a minimum residual maturity of one year within USD 5 billion category. “…all investments by long-term FPIs (sovereign wealth funds, multilateral agencies, endowment funds, insurance and pension funds and foreign central banks) in the USD 5 billion government debt limit shall continue to be made in government bonds having a minimum residual maturity of one year,” Sebi said in a circular.
