Defining Standby Letter of Credit

What is an SBLC?

A Standby Letter of Credit is a written undertaking by a bank on behalf of its client, known as the applicant, to provide payment to a beneficiary if the applicant fails to fulfill its financial obligations or meet specified conditions outlined in the SBLC.

The Mechanics of an SBLC

1. Application and Issuance

  • Applicant’s Request: The process begins when the applicant (buyer) requests an SBLC from their bank, outlining the terms and conditions of the transaction.
  • Bank’s Assessment: The bank evaluates the creditworthiness of the applicant and assesses the viability of the transaction. If approved, the bank issues the SBLC.

2. SBLC Terms and Conditions

  • Specific Conditions: The SBLC details specific conditions that must be met for the beneficiary (seller) to trigger the payment. These conditions are predefined and agreed upon by both parties.

3. Presentation of Documents

  • Beneficiary’s Submission: The beneficiary, upon fulfilling the conditions of the transaction, submits the required documents to the issuing bank.

4. Payment or Performance Guarantee

  • Issuing Bank’s Obligation: If the beneficiary’s documents comply with the terms and conditions of the SBLC, the issuing bank is obligated to make payment to the beneficiary. This payment serves as a guarantee of the applicant’s performance.

Types of SBLCs

Performance SBLC

  • Ensuring Contractual Performance: This type of SBLC guarantees that the applicant will fulfill the terms of a contract, providing assurance to the beneficiary.

Financial SBLC

  • Guaranteeing Financial Obligations: Used to guarantee payment of a financial obligation, such as a loan or payment for goods and services.

Bid Bond SBLC

  • Securing Bids in Tenders: Issued to support the applicant’s bid in a tender process, assuring the tendering party of the applicant’s financial capability.

Key Considerations

1. Irrevocable Nature

  • Binding Commitment: An SBLC is typically irrevocable, meaning that it cannot be canceled or amended without the consent of all parties involved. This provides a binding commitment to the beneficiary.

2. Independence from the Underlying Contract

  • Separation from Transaction Terms: The SBLC is independent of the underlying transaction. Any disputes or issues in the transaction itself do not affect the validity of the SBLC.

3. Expiration and Renewal

  • Time Constraints: An SBLC has a specified validity period. If the beneficiary fails to make a claim within this period, the SBLC becomes null and void. It can be renewed, if needed.


In conclusion, a Standby Letter of Credit operates as a risk mitigation and payment assurance tool in international trade. Its structured process, with clearly defined terms and conditions, ensures a secure environment for both buyers and sellers. As businesses engage in global transactions, understanding the comprehensive workings of an SBLC becomes crucial for leveraging its benefits and fostering confidence in the intricacies of cross-border trade.
