Although they also have the option to open a Non-Resident External (NRE) fixed deposit account, that account will be maintained in rupees, where foreign currency will first be converted into rupees, and then the FD will be created. FCNR(B) is opened in the foreign currency only, and thus, the original denomination remains the same. There is no rupee exposure, and therefore, the account holders can avoid the risk of exchange rate fluctuations and earn risk-free returns. Another benefit of FCNR is that the principal and interest are both entirely tax-free and fully repatriable. This is the reason experts see this as an opportunity for those having surplus funds to earn risk-free, tax-free returns.
