What is a Letter of Credit & How Does it Works?
Parties Involved; Types & Documents Required
A letter of credit is an independent undertaking from the issuer, promising that subject to fulfillment of specific terms and conditions the party in whose favor the undertaking has been issued will get paid even if the party on whose behalf the issuer has given the undertaking refuses to pay. Generally issued by an importer’s bank, the letter of credit ensures the beneficiary will be paid once the conditions of the letter of credit have been met.
The letter of credit can be used for both inland and cross-border trade. It is normally issued by the buyer’s bank as an undertaking to the seller.

Parties Involved in Letter of Credit
- APPLICANT– The buyer of the goods/services (importer) on whose behalf the letter of credit is issued by the issuing bank.
- BENEFICIARY – The seller of the goods/services (exporter) in whose favor the letter of credit is issued and who obtains payment on presentation of documents complying with the terms and conditions of the LC.
- ISSUING BANK– The bank which issues the credit and undertakes to make the payment on behalf of the applicant as per terms of the L/C.
- ADVISING BANK– Banks which advise the LC, certifying its authenticity to the beneficiary, and is generally a bank operating in the country of the beneficiary.
- CONFIRMING BANK– A bank that adds its irrevocable undertaking to the LC opened by another Bank and thereby undertakes responsibility for payment/ acceptance/ negotiation/incurring deferred payment under the credit in addition to that of the Issuing Bank. It is normally a bank operating in the country of the beneficiary and hence its undertaking adds to the acceptability of the LC for the beneficiary. This is being done at the request/authorization of the Issuing Bank.
- NOMINATED BANK- A Bank in the exporter’s country which is specifically authorized by the Issuing Bank to receive, negotiate, etc., the documents and pay the amount to the exporter under the LC.
- REIMBURSING BANK – Bank is authorized to honor the reimbursement claim made by the paying, accepting, or negotiating bank. It is normally the bank with which Issuing Bank has Nostro Account from which the payment is made to the nominated bank.
