Letter of credit process: end-to-end operations

Follow a commercial documentary credit from application and issuance through shipment, document examination, settlement and closure.

Purpose

Connect the commercial trade flow with the bank’s independent documentary undertaking and the operational controls required at every stage.

Standards context

Rules and transaction hierarchy

  • The issued credit is the primary transaction record
  • UCP 600 applies when the credit expressly incorporates it
  • ISBP 821 supports examination practice under UCP 600
  • Banks examine documents rather than the underlying goods or services
  • Applicable law, sanctions requirements and institutional procedures remain transaction-specific

Responsibilities

Parties and roles

Applicant or buyer

Requests issuance, supplies approved instructions and reimburses the issuing bank.

Issuing bank

Issues the credit and undertakes to honour a complying presentation according to its terms.

Beneficiary or seller

Ships or performs under the commercial contract and presents the stipulated documents.

Advising bank

Checks apparent authenticity and advises the credit or amendment to the beneficiary.

Nominated or confirming bank

May receive a presentation, honour or negotiate as provided; a confirming bank adds its own undertaking.

Reimbursing bank

May settle an authorized interbank reimbursement claim under the designated arrangement.

Operational sequence

Workflow and control points

01

Application and approval

Validate the applicant, facility, commercial purpose, country and party risks, amount, expiry and documentary requirements.

Control point: Approved application, exposure availability and proposed terms agree before issuance.
02

Issue and advise

Release the authenticated credit to the advising route and establish contingent exposure and fees.

Control point: Parties, amount, currency, availability, expiry, place of presentation and required documents are unambiguous.
03

Ship and prepare documents

The beneficiary performs the underlying contract and prepares the stipulated commercial, transport, insurance or other documents.

Control point: Commercial parties resolve goods and contract issues; banks retain the documentary framework.
04

Present and examine

Log the presentation and examine documents against the credit, incorporated rules and standard banking practice.

Control point: Presentation timing, document set, discrepancies and the examination decision are evidenced.
05

Honour or refuse

Honour a complying presentation or issue an authorized, timely refusal and manage any waiver request without losing documentary control.

Control point: Decision authority, notices and document custody follow the applicable terms and procedure.
06

Reimburse and close

Settle bank and customer obligations, reduce exposure, preserve residual availability where relevant, reconcile fees and retain records.

Control point: Payment, customer reimbursement, contingent exposure, cash and general ledger agree.

Exception handling

Common breaks and response

The commercial contract and issued credit require different documents or dates

Controlled response: Use an authorized amendment where appropriate; do not treat the underlying contract as automatically changing the bank undertaking.

Documents arrive after expiry or outside the stated presentation place

Controlled response: Record the facts, apply the credit and incorporated rules, and follow the approved refusal or escalation process.

The applicant accepts discrepancies informally

Controlled response: Keep the bank’s examination decision, waiver authority and formal communication separate from an informal customer message.

Payment is complete but contingent exposure remains

Controlled response: Reconcile the drawing, customer reimbursement, instrument balance and accounting before further use or closure.

Practical context

Scenario: sight credit with discrepant documents

Documents are presented under a sight credit, but one required date is inconsistent. The bank records the presentation, completes its examination, controls the refusal and applicant waiver process, then either honours under proper authority or retains the refusal outcome and document instructions.

Knowledge check

Check your understanding

Why is a letter of credit described as documentary and independent?Show answer
The bank’s undertaking is governed by the credit and applicable rules, and banks determine compliance from the presented documents. Disputes about the underlying sale do not automatically determine the documentary examination result.
