An NRE Fixed Deposit (FD) is a unique banking product designed for Non-Resident External (NREs) to invest their foreign income in Indian Rupees. It provides higher interest rates, tax advantages in India (particularly for NRE FDs), and allows for complete repatriation (the ability to transfer money back abroad) of both principal and interest, making it a reliable method for enhancing overseas earnings in India. If the account is closed within the first year, there will be loss of interest.
