It is widely used in domestic and international trade to minimise payment risks, build trust between trading partners and facilitate smooth business transactions.

Letter of Credit Meaning

The letter of credit meaning refers to a written commitment issued by a bank stating that the seller will receive payment from the buyer, provided all the terms and required documents mentioned in the credit are submitted correctly.

Simply put, if the buyer cannot pay, the issuing bank becomes responsible for making the payment, provided the seller has complied with all agreed conditions. Businesses commonly use a letter of credit when:

• Trading with overseas suppliers or buyers
• Dealing with new business partners
• Handling high-value shipments
• Reducing payment and delivery risks

Types of Letter of Credit

There are several letter of credit types, each designed for different trade situations.

• Irrevocable and Revocable Letter of Credit

• Irrevocable Letter of Credit: Cannot be changed or cancelled without the consent of all parties. It is the most commonly used type.
• Revocable Letter of Credit: Can be modified or cancelled by the issuing bank without prior approval. It is rarely used in modern trade.

• Sight and Usance Letter of Credit

• Sight LC: Payment is made immediately after the documents are verified.
• Usance LC: Payment is made after a specified credit period, such as 30, 60 or 90 days.

• Confirmed and Standby Letter of Credit

• Confirmed LC: Another bank guarantees payment in addition to the issuing bank, reducing country or bank risk.
• Standby LC: Acts as a financial guarantee and is used only if the buyer fails to make payment.

• Transferable, Revolving and Back-to-Back Letter of Credit

• Transferable LC: Allows the original beneficiary to transfer payment rights to another supplier.
• Revolving LC: Automatically renews for multiple shipments within an agreed limit.
• Back-to-Back LC: Used when intermediaries purchase goods from another supplier using the original LC as security.

Letter of Credit Example

A simple letter of credit example can make the concept easier to understand. Suppose an Indian importer purchases machinery from a manufacturer in Germany. Since both companies are doing business for the first time, the exporter wants payment security.

The importer asks their bank to issue a letter of credit in favour of the German exporter. After shipping the machinery, the exporter submits the required shipping documents to their bank. Once the documents comply with the LC terms, the bank releases payment. The importer then receives the documents needed to collect the shipment. This arrangement protects both businesses from payment and delivery risks.

FAQs

Is a letter of credit the same as a bank guarantee?

No. A letter of credit ensures payment once trade conditions are met, while a bank guarantee compensates the beneficiary only if the applicant fails to fulfil contractual obligations.

Can a small business get a letter of credit?

Yes. Small businesses can obtain a letter of credit if they meet the eligibility criteria and credit requirements set by their bank.

How long does a letter of credit stay valid?

The validity depends on the agreement between the buyer and seller. Most letters of credit remain valid until the shipment and document submission deadlines specified in the credit.

Who pays the charges for a letter of credit?

Typically, the buyer pays the issuance charges, while other fees may be shared depending on the sales contract and agreement between both parties.

Can a letter of credit be cancelled after issuance?

An irrevocable letter of credit cannot be cancelled or amended without the consent of all involved parties. A revocable LC can be cancelled, although it is rarely used.

What happens if shipment arrives after the expiry date?

If the shipment or required documents are presented after the LC expiry date, the bank may reject payment unless the letter of credit is amended and the parties agree to extend its validity.
