A letter of credit is a written commitment from a bank guaranteeing that a buyer’s payment to a seller will be made on time and for the amount specified, provided the seller presents documents that comply exactly with the LC’s terms. Letters of credit are widely used in international trade to manage seller/buyer credit risk and to bridge trust gaps created by distance, different legal systems, and unfamiliar counterparties.

Key takeaways
– A bank guarantees payment to the seller (beneficiary) if the buyer (applicant) fails to pay.
– Banks issue letters of credit only after assessing the buyer’s creditworthiness and usually require collateral or fees.
– Payment is documentary: banks pay based on presentation of compliant documents, not on inspection of goods.
– The ICC’s Uniform Customs and Practice for Documentary Credits (UCP 600) is the standard ruleset governing documentary credits in international trade.
– Common LC types include commercial (documentary) LCs, standby LCs, revolving LCs, confirmed LCs, and transferable LCs.
How a Letter of Credit Works — overview
1. Buyer and seller sign a sales contract that specifies payment by LC.
2. Buyer applies to its bank (issuing bank) for an LC, providing the contract and collateral/credit information.
3. The issuing bank issues the LC and sends it, often via an advising bank, to the seller’s bank (advising/confirming bank).
4. Seller ships the goods/services and presents the required documents (e.g., bill of lading, commercial invoice, insurance certificate) to the advising/negotiating/confirming bank.
5. The bank(s) check document compliance. If documents comply, payment is made (or a commitment to pay is given, depending on LC terms).
6. The issuing bank reimburses the paying/confirming bank and debits the buyer’s account or uses the collateral/credit line.
Important nuance: banks examine documents, not the goods. Payment depends on strict documentary compliance.
Major types of letters of credit (and when to use them)
– Commercial (Documentary) Letter of Credit:
• Typical LC used to facilitate an international sale.
• Bank pays the seller when documents proving shipment/performance are presented and compliant.
– Standby Letter of Credit:
• Functions as a guarantee or “insurance” — the bank pays only if the applicant fails to perform (e.g., fails to pay or meet contractual obligations).
• Common for performance bonds, construction projects, and warranty guarantees.
– Revolving Letter of Credit:
• Allows multiple draws up to a preset limit over a specified period — useful for repeated shipments between the same trading partners.
– Confirmed Letter of Credit:
• A second bank (usually the seller’s bank) adds its guarantee to the issuing bank’s LC. Used when the seller doubts the issuing bank’s creditworthiness or there’s country risk.
– Transferable Letter of Credit:
• Permits the beneficiary to transfer rights to draw to one or more secondary beneficiaries (useful for intermediaries or traders).
– Red clause / Pre-shipment (Unsecured) LC:
• Provides the seller advance funds before shipment. Riskier for the bank and usually limited by higher fees or collateral.
Costs and collateral
– Banks charge fees for issuing, advising, confirming, amending, negotiating, and reimbursing LCs. Common pricing methods:
• Issuing fee: percentage of the LC amount (example cited: ~0.75% annually; actual rates vary widely by bank, country, credit risk).
• Confirmation fee: additional percentage, based on the confirming bank’s assessment and country/credit risk.
• Advising, negotiation and transfer fees: often flat or per-drawing fees.
• Amendment fees: charged when terms are changed.
– Collateral: banks typically require collateral, cash margin, or a charge against a credit line, especially where the applicant has limited credit history or higher risk.
– Other costs: currency exchange spreads, reimbursement delays, and costs for document discrepancies (which can delay or prevent payment).
Documentary requirements — typical checklist
Banks will pay only on presentation of the exact documents specified in the LC. Typical documents include:
– Commercial invoice
– Full set of clean bills of lading (ocean) or airway bill (air)
– Packing list
– Certificate of origin
– Insurance policy or certificate (when required)
– Inspection or quality certificates (if specified)
– Drafts (bills of exchange) — if documentary credit is “sight” or “usance”
Make a checklist from the LC terms and prepare documents to match wording and dates exactly.
Practical steps: How to apply for and use a Letter of Credit
For buyers (applicants)
1. Negotiate contract terms with seller, specifying LC as payment method and detailing the documents required.
2. Select an issuing bank (usually your bank). Provide contract, KYC documents, and collateral/credit info.
3. Agree LC terms exactly with seller (amount, beneficiary name, port, shipment/incoterms, latest shipment date, documents required, partial shipments allowed or not, expiry date).
4. Authorize the bank to issue the LC and post collateral if required.
5. Monitor shipment documents sent by seller. Approve reimbursement/disbursement to bank per the LC terms.
For sellers (beneficiaries)
1. Require buyer to open an LC instead of relying on buyer credit.
2. Verify issuing bank’s creditworthiness; if concerned, request a confirmed LC from a bank in your jurisdiction.
3. Carefully review LC terms for feasibility: shipment dates, allowed documents, partial shipments, transshipment, and any technical or documentary inconsistencies.
4. Ship goods and assemble documents exactly as stated in the LC.
5. Present documents to the negotiating/confirming bank before expiry; follow up on any discrepancies immediately.
For banks / advising/confirming banks
– Check authenticity of the LC (advise) before shipment.
– If confirming, take on the payment obligation in addition to reviewing documents for compliance.
– Negotiate and forward documents under agreed terms.
Practical steps for making a claim under a Standby Letter of Credit
1. Determine if the applicant triggered a default or failure as defined by the standby LC.
2. Serve any required notices to the applicant/beneficiary per the contract (contractual requirements often precede payment).
3. Prepare a demand for payment with the documents expressly required by the standby LC (often a signed statement of default and any supporting documents).
4. Present the demand to the issuing bank and request payment per the LC terms.
5. If denied, review the bank’s reasons for refusal, consult counsel, and pursue dispute resolution per the LC and underlying contract.
Real-world example (simple)
– Exporter in Country A sells machinery to importer in Country B. Importer’s bank issues a confirmed irrevocable LC for $500,000, payable upon presentation of a commercial invoice, clean bill of lading, packing list, and insurance certificate. The exporter ships the machinery, obtains the required documents, presents them to the confirming bank, and receives payment when documents comply. If the importer defaults afterward, the exporter has been paid by the confirming bank.
Common pitfalls and best practices
– Pitfall: Documents don’t match the LC wording exactly — banks can refuse payment for even minor discrepancies.
Best practice: Prepare a document checklist and cross-check every field (names, dates, invoice numbers, terms).
– Pitfall: Relying on an unconfirmed LC from a weak issuing bank or high-country risk.
Best practice: Request confirmation or require payment on sight by a strong bank.
– Pitfall: Vague or inconsistent LC terms vs. the sales contract.
Best practice: Harmonize LC wording with the sales contract before issuance.
– Pitfall: Late presentation or missed expiry date.
Best practice: Track shipment timelines and present documents well before expiry.
– Pitfall: Not understanding whether LC is revocable or irrevocable.
Best practice: Use irrevocable LCs for trade certainty; most modern documentary credits are irrevocable.

Frequently asked questions (short answers)
– How does a letter of credit work?
The issuing bank guarantees payment to the beneficiary upon presentation of documents that meet the LC’s terms.
– When does payment occur with an LC?
Payment occurs only after required documents are presented and deemed compliant with the LC; timing can be “at sight” (immediate) or “usance/term” (deferred).
– What’s the difference between a commercial LC and a revolving LC?
A commercial LC is for a single shipment/transaction. A revolving LC permits multiple draws up to a limit over a period for repeated shipments.
Checklist before you proceed with an LC
– Ensure LC terms exactly match the sales contract.
– Verify issuing bank reputation and request confirmation if needed.
– Prepare a complete documents list and timeline for presentation.
– Clarify who bears which fees and any collateral requirements.
– Confirm permitted ships/ports, partial shipments, transshipment rules, and expiry date.
