Importers are no more interested to import through opening L/C. Under L/C, importers have to provide required margin and sufficient security to their banks in order to confirm L/Cs. Even for a successful importer, there comes a time when the growing requirements for L/Cs margin go beyond the importer's financing ability and L/Cs coverage exceeds the security available to give to the bank. Moreover, importers need to approach banks for issuing L/Cs on each occasion of importing goods from abroad, which is really time consuming for foreign trade.
