I am senior citizen looking for safe fixed income investments which fetch better returns than bank FDs. Tamilnadu Power Finance and Infrastructure Development Corporation and Tamilnadu Road Transport Development Finance Corporation offer to senior citizens, 9.75%, 9.83% and 10.2% annual interest on their FDs for three to five years, depending on the periodicity of payout i.e monthly (9.75%), quarterly (9.83%) or yearly (10.2%).
Kindly advise whether these are safe FDs.
