While a commercial Letter of Credit (LC) helps facilitate payment for goods or services, a Standby Letter of Credit (SBLC) serves a different but equally important purpose , it acts as a safety net in case one party fails to meet their contractual obligations.
Used widely in both international trade and domestic transactions, standby LCs provide reassurance that, even if something goes wrong, the beneficiary will still be protected.
What Is a Standby Letter of Credit?
A Standby Letter of Credit is a guarantee issued by a bank on behalf of a customer (the applicant), promising to pay the beneficiary if the applicant fails to perform under a contract , for example, to deliver goods, complete a project, or make a payment.
Unlike a traditional LC, which is a primary payment mechanism, an SBLC functions as a secondary obligation , it is only drawn upon if the applicant defaults.
In practice, it works much like an insurance policy for performance or payment.
Governing Rules: UCP 600 and ISP98
Standby Letters of Credit can be issued under:
- UCP 600 (Uniform Customs and Practice for Documentary Credits) , commonly used for both commercial and standby LCs. or
- ISP98 (International Standby Practices) , a more specialised set of rules developed by the International Chamber of Commerce (ICC) specifically for standby LCs.
While both rule sets are internationally recognised, ISP98 gives more detailed guidance tailored to standby credit scenarios, such as non-performance or late payment.
How a Standby LC Works
The process is similar to a traditional LC, but the intention is different:
- Application and Issuance:
The applicant requests their bank (the issuing bank) to issue an SBLC in favour of the beneficiary.
The SBLC moves electronically through the SWIFT network, typically using the MT760 message type (distinct from MT700 used for commercial LCs). - Advising:
The beneficiary’s bank (the advising bank) receives and authenticates the SBLC. - Obligation Period:
The SBLC remains in force for a defined period. It usually not used unless the applicant fails to meet their contractual commitments. - Claim or Drawing:
If the applicant defaults, the beneficiary may make a demand for payment by presenting a written statement and any required documents, declaring the applicant has failed to perform. - Payment:
The issuing bank reviews the claim under UCP 600 or ISP98 rules. If the presentation is compliant, payment is made to the beneficiary.
Common Uses of Standby Letters of Credit
SBLCs are highly versatile and used across a range of industries and transactions, including:
- Performance Guarantees: Ensuring contractors complete projects as agreed.
- Financial Guarantees: Securing repayment of loans or lease obligations.
- Payment Guarantees: Protecting sellers against non-payment for goods or services.
- Tender or Bid Bonds: Assuring a buyer the bidder will honour their offer.
- Advance Payment Guarantees: Ensuring return of advance payments if the supplier fails to deliver.
Benefits of a Standby LC
- For Beneficiaries: Provides assurance of payment or compensation in the event of default.
- For Applicants: Enhances creditworthiness and supports business relationships by offering a reliable financial commitment.
- For Both Parties: Offers an internationally recognised, regulated mechanism backed by UCP 600 or ISP98, transmitted securely via SWIFT MT760 messages.
Key Differences Between Standby and Commercial LCs
| Feature | Commercial LC | Standby LC |
| Purpose | Primary payment method | Secondary payment guarantee |
| Typical Use | Payment for goods/services | Guarantee of performance or payment |
| Rules | UCP 600 | UCP 600 or ISP98 |
| SWIFT Message Type | MT700 | MT760 |
| Trigger for Payment | Presentation of shipping and trade documents | Proof of non-performance or default |
Final Thoughts
A Standby Letter of Credit gives a critical safety mechanism in both domestic and international business. Whether securing a performance bond, guaranteeing payment, or underpinning a financial obligation, SBLCs enhance trust and reduce counterparty risk.
Backed by UCP 600 or ISP98 and transmitted securely via SWIFT MT760, standby LCs remain one of the most effective instruments for managing contractual risk and ensuring peace of mind in global trade.
In short , while a commercial LC pays for performance, a standby LC pays for non-performance.
