Standby letters of credit at a glance
In international trade and large-scale corporate contracting, there are substantial structural risks to both buyers and sellers. Generally speaking, buyers fear non-performance and sellers fear non-payment. Where some traditional finance instruments facilitate trade by triggering payment upon successful delivery, risk mitigation often requires a different structural approach: a financial backstop should things go wrong. Standby letters of credit provide such a backstop.

How standby letter of credit works
A standby letter of credit (SBLC), in its most basic terms, is a legal commitment issued by a bank on behalf of a client that guarantees payment to a third party should their client default on their contractual or financial obligations. It essentially represents a relationship between three parties:
- Applicant: The party who requests the SBLC to assure their creditworthiness to the counterparty.
- Beneficiary: The party who receives the SBLC and has the right to draw funds should the applicant default.
- Issuing Bank: The financial institution that evaluates the applicant’s credit, issues the instrument, and assumes the financial liability to pay the beneficiary upon a compliant demand.
Types of standby letter of credit
Credit assessment and applicationThe applicant requests an SBLC. The bank evaluates creditworthiness and exposure.
Issuance and delivery to beneficiaryThe bank issues the SBLC under ISP98 or UCP600 and sends it to the beneficiary.
Contract performance periodThe applicant performs its contractual obligations while the SBLC remains in force.
Demand and drawing (if triggered)If the applicant defaults, the beneficiary submits a compliant demand; the bank pays solely on documentary compliance.
Reimbursement and resolutionThe bank recovers funds from the applicant. Any contractual disputes are handled separately.
Types of SBLCs
Financial SBLCs
A financial SBLC acts as a guarantee for direct monetary obligations, ensuring a supplier or lender receives payment for goods or services delivered to the buyer should the buyer experience liquidity constraints or insolvency. Financial SBLCs are often used to secure open-account trade terms, back long-term lease agreements for corporate real estate, or support short-term corporate debt programs (such as commercial paper).
Performance SBLCs
Performance SBLCs guarantee the completion of non-financial, operational obligations. For example, should a contractor fail to complete a project according to agreed specifications or timelines, the project owner can draw down on the SBLC to cover the financial losses of hiring a replacement. Performance SBLCs are a staple in the construction, engineering, and infrastructure sectors.
Regulatory frameworks
- ISP98
- The International Standby Practices 1998 (ISP98) are a set of rules specifically formulated to govern SBLCs. ISP98 addresses the unique realities of standby instruments like SBLCs, making it the preferred framework for sophisticated corporate treasury departments.
- UCP600
- The Uniform Customs and Practice for Documentary Credits (UCP600) were originally designed for commercial letters of credit but can be applied to SBLCs. However, there is the potential for ambiguities when applied to non-performance instruments as UCP600 assumes the regular presentation of shipping documents like bills of lading.
FAQs
A commercial letter of credit is a primary payment mechanism used to complete a transaction; it is intended to be drawn. An SBLC, conversely, is a “safety net” that the bank expects will never be drawn upon – payment is only triggered if the applicant fails to perform or defaults. Rather than being a primary payment mechanism, an SBLC is a structural transfer of credit risk from the corporate applicant to the issuing bank.
Strictly speaking, no – the SBLC is a completely separate transaction from the underlying buyer/seller commercial contract that it supports. The issuing bank is solely concerned with the terms of the SBLC itself, and not whether a breach of the underlying contract has taken place; if a beneficiary presents a demand that matches the requirements specified in the SBLC, the bank is legally obliged to pay. Banks cannot investigate the underlying dispute for a breach of contract, nor can an applicant try to block payment based on claims that their performance was adequate as per the commercial contract (with the exception of established, egregious fraud on the part of the beneficiary).
Are there any risks associated with SBLCs?
Yes - SBLCs reduce credit and performance risk for the beneficiary, but introduce operational and financial risks for the applicant. Banks pay out solely on documentary compliance, meaning applicants face the risk of “unfair calling” - i.e., a beneficiary draws down on the SBLC prematurely or fraudulently despite the applicant having fulfilled their duties. In such instances, applicants can sue the beneficiary for breach of contract to recover the funds, but the immediate liquidity drain can cause financial strain.Corporate treasury teams must implement rigorous controls to protect applicants from these risks. This can be done by:
· Drafting narrow, explicit documentary requirements into the SBLC text (e.g., requiring an independent third-party inspection certificate for a drawing).
· Closely tracking expiry dates to avoid unexpected extensions or unintended automatic renewals.
· Ensuring the credit lines utilised for SBLC issuance are properly factored into the organisation’s overarching leverage and liquidity calculations.Functionally speaking, no - they are both risk mitigation instruments where financial institutions provide a backup payment “safety net” and are drawn upon non-performance or default by the applicant. An SBLC is essentially a demand/bank guarantee structured as a letter of credit; they are common in the United States and with American banks, whereas the rest of the world generally uses demand guarantees.
Summary
Standby letters of credit provide a robust financial safety net in international trade and corporate contracting by guaranteeing payment or performance if an applicant defaults. They transfer credit risk to the issuing bank, operate under clear ICC rule frameworks, and support both financial and operational obligations. While they reduce risk for beneficiaries, they introduce operational and liquidity risks for applicants, making strong treasury controls essential.
