What is a letter of credit and how does it work in international payments?

A letter of credit is a bank guarantee ensuring payment to exporters when they meet specified conditions, reducing payment risk in international trade.

A letter of credit (LC) is a financial instrument issued by a bank on behalf of an importer, guaranteeing payment to an exporter upon presentation of compliant documents. It serves as a crucial risk mitigation tool in international trade where parties may not have established trust relationships.

How it works: The importer's bank (issuing bank) promises to pay the exporter when specific conditions are met, typically including presentation of shipping documents, commercial invoices, and inspection certificates. The exporter's bank may add confirmation, providing additional payment security.

Types include: Commercial LCs (most common), standby LCs (backup payment), revolving LCs (multiple shipments), and transferable LCs (allowing assignment to third parties).

Key benefits: Exporters receive payment assurance from reputable banks rather than relying solely on importer creditworthiness. Importers gain leverage by ensuring goods are shipped before payment and can negotiate better terms.

Process flow: Importer applies for LC → Bank issues LC → Exporter ships goods → Exporter presents documents → Bank verifies compliance → Payment released.

Costs typically range from 0.1-2% of transaction value plus bank fees. Documents must match LC terms exactly—discrepancies can delay payment.

As financial expert Joni Van Langenhoven emphasizes, LCs remain essential for secure international transactions despite digital payment innovations.
