In a letter of credit, the issuing bank creates the documentary payment undertaking at an applicant's request or on its own behalf.
In a letter of credit, the issuing bank is the bank that issues the credit at an applicant’s request or on its own behalf. Its issuance creates a definite undertaking to honor a complying presentation under the credit’s terms and incorporated rules. The issuing bank relies separately on the applicant’s reimbursement obligation, collateral, and creditworthiness.
When UCP 600 applies, a credit is irrevocable even if it does not say so. The issuing bank becomes bound from the time it issues the credit. If stipulated documents are presented and constitute a complying presentation, the bank must honor according to the credit’s availability method.
Honor can mean:
Negotiation is a distinct concept involving purchase of drafts or documents by a nominated bank. The issued credit should identify where and how it is available rather than relying on the vague instruction “pay beneficiary.”
| Party or bank | Core role | Does it automatically undertake payment? |
|---|---|---|
| Applicant | Requests issuance and reimburses the issuing bank under a separate agreement | No bank undertaking; remains commercially liable under its contracts |
| Beneficiary | Presents documents and draws under the credit | Entitled to rely on the credit subject to its terms |
| Issuing bank | Issues the credit and honors a complying presentation | Yes, under the issued credit |
| Advising bank | Checks apparent authenticity and transmits the credit accurately | No, not merely by advising |
| Nominated bank | Bank with which the credit is available or authorized to act | Not automatically unless it expressly agrees or has another undertaking |
| Confirming bank | Adds its own undertaking when authorized or requested | Yes, within the confirmation and credit terms |
| Reimbursing bank | Acts under bank-to-bank reimbursement instructions | Role is governed by the reimbursement authorization and applicable rules |
A single institution can perform several roles, but each role should be proved by the authenticated credit, advice, confirmation, nomination, or reimbursement record.

This is a simplified commercial-credit flow. A confirming bank, deferred maturity, reimbursement bank, negotiation, transfer, or financing can add steps and separate obligations.
Under UCP 600, a nominated bank acting on its nomination, a confirming bank, and the issuing bank each have a maximum of five banking days following the day of presentation to determine whether a presentation complies. The period is not shortened by an approaching expiry or latest presentation date.
The bank examines the documents on their face against:
The bank does not determine whether the physical goods match the documents. It also does not automatically know whether a signature, certificate, or shipment is genuine merely because the document appears regular. Fraud, forgery, sanctions, and governing-law issues may require separate analysis.
If the bank decides to refuse, the applicable notice must identify the discrepancies and disposition of documents within the required process. An issuing bank may approach the applicant for waiver, but doing so does not extend the examination or refusal deadline.
The issuing bank’s obligation to the beneficiary is independent from its right to reimbursement from the applicant. That independence is why the bank underwrites the applicant before issuance and may require:
The bank’s contingent exposure becomes funded when it honors or reimburses a drawing. If the applicant cannot reimburse, the issuing bank still may have an obligation under a complying credit and must rely on its credit agreement and collateral for recovery.
An issuing bank opens a $400,000 sight credit for an importer buying packaged food-processing equipment. The credit requires a signed invoice, clean on-board bill of lading dated no later than June 30, packing list, and certificate of origin. The exporter presents all documents on July 5 before expiry.
The documents appear to comply. On July 7, the applicant tells the bank that a factory manager believes the equipment model is unsuitable and asks the bank to stop payment.
The issuing bank does not inspect the equipment or resolve the product dispute. If the presentation complies and no separate legal exception applies, the bank’s documentary undertaking remains distinct from the applicant’s sales-contract complaint. The applicant may pursue contractual remedies against the seller, but it cannot assume that the issuing bank may disregard a complying presentation.
Now change one fact: the bill of lading shows shipment on July 2, after the June 30 latest shipment date. The bank has a documentary discrepancy. It can seek the applicant’s waiver while preserving the required notice process, but the applicant’s willingness to accept late shipment does not retroactively make the original presentation compliant.
