What Is a Letter of Credit (LC)? 

A Letter of Credit (LC) is one of the most secure and widely used payment methods in international trade. It ensures that exporters receive payment on time and importers receive goods as agreed. Banks play a major role as a trusted third party, reducing financial and transactional risks for both sides. 

Key Insights 

• A Letter of Credit ensures secure and risk-free payment between international buyers and sellers. 

• It protects exporters from payment failure and assures importers that goods will be shipped as per agreed terms. 

• The LC process works through banks, ensuring verification of documents before releasing payment. 

• Choosing the right type of LC and maintaining accurate documentation minimizes trade risks. 

How a Letter of Credit (LC) Works 

A Letter of Credit works by involving the buyer’s bank, which commits to pay the exporter after verifying shipping and commercial documents. Once the exporter submits accurate documents, the bank releases payment. This process ensures safe transactions, minimizes default risk, and streamlines global trade between unfamiliar trading partners. 

Who Issues the Letter of Credit (LC)? 

A Letter of Credit (LC) is issued by the buyer’s bank, also known as the issuing bank, to guarantee secure payment to the exporter. When the importer applies for an LC, the issuing bank evaluates their creditworthiness and agrees to take responsibility for paying the exporter once all required shipping and commercial documents match the LC terms. Sometimes, a confirming bank or advising bank is also involved to add extra security for the seller. The issuing bank plays a crucial role in reducing risk, ensuring trust, reliability, and smooth international trade transactions between unfamiliar parties across borders. This mechanism promotes safe and transparent global trade dealings. 

Key Components of a Letter of Credit 

• Applicant: The importer who requests the LC 

• Beneficiary: The exporter who receives payment 

• Issuing Bank: The buyer’s bank 

• Advising/Confirming Bank: The seller’s bank 

• Negotiating Bank: Reviews and checks documents 

Types of Letters of Credit 

1. Revocable LC 

Can be changed or canceled without the exporter’s consent. 

2. Irrevocable LC 

Cannot be altered without agreement from all parties (most common). 

3. Commercial Letter of Credit 

A standard LC where the buyer’s bank guarantees payment to the seller once all required documents are correctly submitted. It ensures secure trade transactions and reduces financial risk for both parties. 

4. Standby Letter of Credit (SBLC) 

Acts as a financial backup. Payment is made only if the buyer fails to meet obligations. It provides security and functions like a guarantee rather than a primary payment method. 

5. Revolving Letter of Credit 

Used for repeated shipments over a period without issuing a new LC each time. It automatically renews by time or value, making trade faster and convenient for long-term buyers and suppliers. 

6. Traveler’s Letter of Credit 

Issued to travelers for withdrawing money or making payments abroad. It ensures banks in foreign countries honor the credit, providing secure access to funds during international travel. 

7. Confirmed Letter of Credit 

A second bank (confirming bank) adds its guarantee along with the issuing bank. This provides extra security to the exporter, especially when the buyer’s bank or country is considered high-risk. 

How a Letter of Credit Works – Step-by-Step Eplained 

1. Buyer and Seller Agree on LC Payment 

The importer (buyer) and exporter (seller) finalize a trade agreement and choose a Letter of Credit as the payment method for security. 

2. Buyer Applies for the LC 

The importer requests their issuing bank to issue an LC in favor of the exporter, providing contract details and required documents. 

3. Issuing Bank Sends LC to Advising Bank 

The issuing bank prepares the LC and sends it to the advising bank (usually in the exporter’s country) for verification and delivery to the exporter. 

4. Exporter Reviews the LC 

The exporter checks all LC terms, conditions, and required documents. If everything matches, the exporter proceeds with production and shipment. 

5. Exporter Ships Goods 

The exporter ships the goods and collects shipping documents like Bill of Lading, Commercial Invoice, Packing List, etc. 

6. Exporter Submits Documents to Bank 

The exporter submits all required documents to the advising bank, which forwards them to the issuing bank for validation. 

7. Issuing Bank Verifies Documents 

The issuing bank checks whether all documents strictly comply with LC terms. This step ensures accuracy and authenticity. 

8. Payment Is Released 

If documents are correct, the issuing bank releases payment to the exporter (via advising bank). 
If discrepancies exist, payment may be delayed until corrected. 

9. Issuing Bank Gives Documents to Buyer 

After payment, the issuing bank hands over the shipping documents to the importer to claim the goods. 

10. Buyer Collects the Goods 

The importer uses the documents to clear customs and receive the goods from the shipping line.
