Fully Convertible Non-Resident Rupee (FCNR). This account is similar to the NRE account except that the funds are held in foreign currencies and can be maintained in Pound Sterling,U.S. Dollar, Euro and Japanese Yen. FCNR accounts can be maintained only in the form of term deposits, i.e. a deposit kept for fixed periods ranging from 6 months to 3 years.

Balances held in NRE accounts can be repatriated abroad freely, whereas funds in NRSR and NRO account cannot be normally remitted abroad but have to be used only for local payments in rupees. Consequently, funds remitted from abroad or local funds which can otherwise be remitted abroad to the accountholder can only be credited to NRE accounts
