What Is a Letter of Credit (LC)?
A letter of credit (LC) is a financial instrument and a payment mechanism used predominantly in international trade to guarantee payment from a buyer to a seller. It falls under the broader category of trade finance, providing a secure method for transactions between parties that may not have an established relationship. Essentially, a letter of credit is a commitment by a bank (the issuing bank) on behalf of a buyer (the applicant) to make a payment to a seller (the beneficiary), provided that the seller presents specific, conforming documents as proof that the goods or services have been shipped or provided according to agreed-upon terms. This mechanism significantly reduces risk management concerns for both the buyer and the seller, ensuring that the seller is paid and the buyer receives the specified goods.
History and Origin
The concept of a letter of credit is deeply rooted in the history of global commerce, with its origins tracing back to ancient civilizations. Early forms of credit and promises of payment, often recorded on clay tablets, were utilized in Mesopotamia around 3000 BCE to facilitate long-distance trade. Ancient Greek and Roman societies also developed instruments resembling letters of credit to avoid the physical transport of specie during commercial exchanges.6,5,4
The modern form of the letter of credit began to emerge in medieval Italy, particularly during the Renaissance in bustling trade cities like Venice, Genoa, and Florence. Merchant banks, such as those established by the Medici family, developed sophisticated systems to guarantee payments for goods transported across vast and often perilous territories.3,2 These early "letters of payment" or "letters of credit" assured merchants that they would receive funds upon the delivery of goods, bolstering trust and expanding trade networks.1
A significant step towards standardization occurred in the 20th century with the International Chamber of Commerce (ICC). In 1933, the ICC oversaw the preparation of the first Uniform Customs and Practice for Documentary Credits (UCP), creating a voluntary framework that commercial banks could apply to transactions worldwide. The UCP has been revised multiple times, with the current version being UCP 600, effective since July 1, 2007., [ICC UCP 600]
Key Takeaways
- A letter of credit (LC) is a bank's commitment to pay a seller on behalf of a buyer, contingent on specific documents being presented.
- It serves as a critical risk management tool in international trade, mitigating payment and delivery risks for both parties.
- The LC introduces a bank as an intermediary, shifting the credit risk from the buyer to a financial institution.
- Payment under an LC is based strictly on the presentation of conforming documents, not on the underlying goods themselves.
- The Uniform Customs and Practice for Documentary Credits (UCP), issued by the International Chamber of Commerce, provides the global framework for LC operations.
Interpreting the Letter of Credit
Interpreting a letter of credit involves understanding that its primary function is to provide security by placing a bank's creditworthiness behind the buyer's payment obligation. For the exporter (beneficiary), an LC means assurance of payment as long as they meet the stipulated conditions by presenting the required documents (e.g., bill of lading, commercial invoice, packing list). The bank is obligated to honor the payment regardless of any dispute between the buyer and seller over the goods, as long as the documents comply with the LC's terms. This principle of "documentary compliance" is fundamental to a letter of credit. For the importer (applicant), it ensures that payment will only be made once proof of shipment or performance is provided.
Hypothetical Example
Consider a scenario where "AquaClean," a water purification system manufacturer in the United States, wants to import specialized filters from "PureFlow Components," a supplier in Germany. AquaClean (the applicant) and PureFlow (the beneficiary) agree to use a letter of credit to secure their transaction, valued at $100,000.
- Agreement: AquaClean and PureFlow sign a sales contract, specifying an LC as the payment method.
- LC Issuance: AquaClean applies to its bank, "First Global Bank" (the issuing bank), for a letter of credit in favor of PureFlow. First Global Bank assesses AquaClean's creditworthiness.
- LC Transmission: First Global Bank issues the LC and sends it to PureFlow's bank, "EuroTrade Bank" (the advising bank) in Germany. EuroTrade Bank advises PureFlow of the LC.
- Shipment: PureFlow reviews the LC, confirms it aligns with the contract, and then ships the filters to AquaClean.
- Document Presentation: After shipment, PureFlow presents the required documents (e.g., commercial invoice, bill of lading, certificate of origin) to EuroTrade Bank.
- Document Examination: EuroTrade Bank examines the documents to ensure they strictly comply with the terms of the letter of credit.
- Payment: If the documents are compliant, EuroTrade Bank pays PureFlow, then forwards the documents to First Global Bank. First Global Bank then debits AquaClean's account and releases the documents to AquaClean, allowing AquaClean to take possession of the filters.
This process ensures that PureFlow is paid promptly upon fulfilling its shipping obligations, and AquaClean is assured that payment is made only once the shipment is verified by the bank's receipt of conforming documents.
Practical Applications
Letters of credit are essential tools in trade finance, particularly in cross-border transactions where trust between parties might be limited, or when dealing with unfamiliar markets. They are widely used in:
- International Shipments: LCs secure payment for goods shipped over long distances, such as raw materials, manufactured goods, and commodities. They are particularly vital for bulk purchases or customized orders.
- Mitigating Country Risk: In regions with economic instability or unpredictable legal systems, an LC can provide reassurance by introducing a reputable bank into the transaction, thereby reducing exposure to country-specific payment risks.
- Financing Solutions: LCs can be structured to provide a form of short-term financing, allowing the buyer time to sell the goods before payment is due to the issuing bank, or enabling the seller to obtain pre-shipment financing from their bank against the assurance of the LC.
- Supply Chain Operations: While more traditional, LCs still play a role in complex global supply chain finance, especially where suppliers need payment guarantees to produce and ship goods. [Federal Reserve Bank of San Francisco]

Limitations and Criticisms
While providing significant security, letters of credit also present certain limitations and potential criticisms:
- Complexity and Cost: LCs involve multiple parties, extensive documentation, and strict adherence to terms, making them more complex and costly than other payment methods like open account trading. Banks charge fees for issuing, advising, and confirming LCs, which can add to transaction expenses.
- Strict Documentary Compliance: The principle of strict compliance means that even minor discrepancies in documents can lead to payment delays or refusal. This can create challenges for the exporter, who must ensure every detail aligns perfectly with the LC's requirements. This often necessitates significant administrative effort.
- Bank's Role: A letter of credit is a financial obligation of the issuing bank, not the buyer. The bank deals with documents, not goods. If the goods shipped are faulty or not as described, but the documents conform, the bank is still obligated to pay. The buyer's recourse in such a case would be against the seller directly, not the bank.
- Fraud Risk: While generally secure, LCs are not immune to fraud, particularly involving forged or falsified documents. Vigilance is required from all parties.
- Digitalization Challenges: Despite the push for digital transformation in financial institutions, trade finance, including LCs, has historically lagged in adopting fully paperless processes, leading to inefficiencies.

Letter of Credit (LC) vs. Bill of Exchange
While both a letter of credit (LC) and a bill of exchange (B/E) are instruments used in trade, they serve distinct primary functions and carry different implications for payment security.
Feature | Letter of Credit (LC) | Bill of Exchange (B/E) |
---|---|---|
Primary Function | A bank's guarantee of payment to the seller, conditional on document compliance. | An order from one party (drawer) to another (drawee) to pay a third party. |
Payer | Primarily the issuing bank. | Primarily the drawee (buyer), or a bank if accepted and discounted. |
Nature of Obligation | Independent bank undertaking; irrevocable. | A demand for payment; can be negotiable. |
Security | High security for the seller, as it's a bank's commitment. | Less inherent security; relies on the drawee's creditworthiness. |
Complexity | More complex with detailed conditions and documents. | Simpler, often used in more established trading relationships. |
The primary confusion arises because a bill of exchange is often one of the key documentary collection requirements under a letter of credit. However, an LC is a separate, overarching payment undertaking by a bank, whereas a B/E is a specific instruction to pay. The LC provides the bank's commitment to honor the B/E (and other documents) if they are compliant, thus adding a layer of banking security that a standalone bill of exchange does not inherently possess.
FAQs
Q1: Who benefits most from a letter of credit?
Both the buyer and the seller benefit from a letter of credit. The beneficiary (seller) gains assurance that they will receive payment as long as they meet the terms specified in the LC. The applicant (buyer) is assured that the bank will only release payment once the seller provides proof of shipment or fulfillment, as evidenced by the required documents.
Q2: Is a letter of credit always irrevocable?
Most commercial letters of credit today are issued as irrevocable, meaning they cannot be canceled or amended without the agreement of all parties involved, particularly the issuing bank and the beneficiary. This provides a strong level of security for the seller. Some historical or specialized LCs might be revocable, but they are rare in modern international trade.
Q3: What happens if documents don't match the LC?
If the documents presented by the seller do not strictly conform to the terms and conditions stated in the letter of credit, they are considered "discrepant." The issuing bank can refuse payment. The seller then has to either correct the discrepancies or ask the buyer to waive them. This emphasizes the importance of meticulous attention to detail when preparing and presenting documents under an LC.
