Standby Letter of Credit (SBLC): The Complete Guide
A standby letter of credit (SBLC) is an irrevocable undertaking issued by a bank on behalf of an applicant, guaranteeing payment to a beneficiary if the applicant fails to perform a contractual or financial obligation. SBLCs are issued via SWIFT MT760 and governed by ISP98 or UCP600. Financely arranges SBLC issuance and financing through its structured trade and commodity finance practice.
What Is a Standby Letter of Credit?
A standby letter of credit is a secondary payment undertaking: the issuing bank promises to pay the beneficiary if the applicant (the bank's client) fails to fulfil its contractual obligations. Unlike a documentary letter of credit, which is intended to be drawn upon as part of a normal trade transaction, an SBLC is intended to remain undrawn. It is called upon only in the event of non-performance or default by the applicant.
The SBLC is independent of the underlying contract between the applicant and the beneficiary. The issuing bank's obligation is triggered solely by a complying documentary presentation from the beneficiary, not by proof of the underlying breach. This independence is one of the most important legal features of the instrument.
Performance vs. financial SBLCs: A performance SBLC covers the applicant's failure to perform a contractual obligation, such as failing to deliver goods or complete a project. A financial SBLC covers the applicant's failure to make a financial payment, such as a loan repayment or a lease obligation. Both are structured and issued in the same way; the difference lies in the triggering condition stated in the instrument.
SBLC vs. Bank Guarantee vs. Documentary Letter of Credit
These three instruments are frequently confused. The table below sets out the key distinctions using the definitions and frameworks established by the ICC Academy's comprehensive guide to standby letters of credit.
| Feature | SBLC | Bank Guarantee (Demand) | Documentary LC |
|---|---|---|---|
| Primary purpose | Security against non-performance or non-payment | Security against non-performance or non-payment | Primary payment mechanism for a trade transaction |
| Intended to be drawn | No: drawn only on default | No: drawn only on default | Yes: drawn upon as part of normal transaction |
| Governing rules | ISP98 or UCP600 (ICC) | URDG 758 (ICC) | UCP600 (ICC) |
| SWIFT message | MT760 | MT760 | MT700 / MT710 |
| Common in | US, Asia, international trade and finance | Europe, Middle East, project finance | Global merchandise trade |
| Documents required to draw | Written demand and SBLC-specified documents | Written demand; often statement of default | Full set of shipping and trade documents |
| Independence from contract | Yes: fully independent | Yes: fully independent under URDG 758 | Yes: independent of underlying sale contract |
How an SBLC Is Issued: The MT760 Process
An SBLC is issued by a bank (the issuing bank) via SWIFT MT760, which is the standardised messaging format used by banks to transmit guarantee and SBLC instruments internationally. The MT760 is transmitted to the beneficiary's bank (the advising or confirming bank), which authenticates the message and notifies the beneficiary that the instrument has been issued in their favour.
The applicant submits an SBLC application to their bank, providing details of the beneficiary, the underlying obligation, the amount, the expiry date, the applicable rules (ISP98 or UCP600), and the drawing conditions.
The issuing bank assesses the applicant's creditworthiness and approves a credit line to cover the SBLC. The applicant may need to provide cash collateral, a counter-guarantee, or other security to support the issuance.
The issuing bank transmits the SBLC text to the beneficiary's bank via authenticated SWIFT MT760. The MT760 contains all material terms: amount, beneficiary, expiry, drawing conditions, and applicable rules.
The beneficiary's bank advises the SBLC to the beneficiary, confirming the instrument is authentic. In some transactions the beneficiary requests the advising bank to also confirm the SBLC, adding the confirming bank's independent payment undertaking.
If the applicant defaults on the underlying obligation, the beneficiary presents a complying drawing demand to the issuing (or confirming) bank. The bank examines the documents and pays if the presentation complies with the SBLC terms.
Common Uses of an SBLC
Trade payment guarantee
An importer's bank issues an SBLC in favour of an overseas exporter, guaranteeing payment if the importer fails to pay under an open account arrangement. The exporter ships goods on open account terms, with the SBLC providing payment security in place of a documentary LC.
Project and construction finance
Contractors and project owners use SBLCs as performance bonds and advance payment guarantees in construction contracts. The beneficiary can draw on the SBLC if the contractor fails to perform or defaults on advance repayment obligations.
Loan collateral (SBLC monetisation)
An SBLC issued by a rated bank can be used as collateral for a loan or credit facility. The lender accepts the SBLC as security, advancing funds against it. This is known as SBLC monetisation and is used in structured finance, real estate, and project funding transactions.
Commodity and energy trading
Commodity traders use SBLCs as credit support in large-volume purchase and supply contracts, particularly where the counterparty requires a bank-backed payment guarantee but the volume or duration makes a documentary LC impractical.
Real estate and lease obligations
Tenants and developers use SBLCs as security deposits for commercial leases and property transactions. The landlord or counterparty holds the SBLC as a guarantee of the tenant's rental obligations, providing recourse in the event of default.
Bid and tender bonds
Companies tendering for large contracts issue SBLCs in favour of the contracting party as bid bonds, providing assurance that, if awarded the contract, the tenderer will execute it. The SBLC is returned or cancelled once a contract is signed.
SBLC Finance and Monetisation
SBLC finance refers to the use of a standby letter of credit as a financial instrument to access funding. SBLC monetisation is the process by which the holder of an SBLC uses it as collateral to obtain a loan or credit line from a financier, typically receiving between 60% and 90% of the instrument's face value as a cash advance, depending on the issuing bank's credit rating and the terms of the SBLC.
Financely arranges SBLC financing and monetisation structures as part of its structured commodity and trade finance mandates. We assess the issuing bank, instrument terms, and monetisation requirements before introducing suitable counterparties.
SBLC fraud risk: The market for SBLC leasing, monetisation, and trading contains a high volume of fraudulent instruments and intermediary scams. Legitimate SBLCs are issued by rated banks via authenticated SWIFT MT760 and are verifiable through the issuing bank directly. Any arrangement involving unrated issuers, paper instruments, or upfront fees to intermediaries before an SBLC is issued should be treated with extreme caution.
SBLC Costs and Fees
| Fee component | Typical range | Notes |
|---|---|---|
| Issuance fee | 1% to 2% per annum on face value | Charged by the issuing bank; reflects applicant credit risk |
| Amendment fee | Fixed per amendment | Charged when terms such as amount or expiry are modified |
| Confirmation fee | 0.5% to 1.5% per annum | Charged by the confirming bank if confirmation is requested |
| Advising fee | Fixed or small percentage | Charged by the beneficiary's bank for advising the instrument |
| Arrangement fee (via broker) | 0.5% to 2% of face value | Charged by arrangers such as Financely for sourcing the issuing bank |
Documentary Letter of Credit vs. SBLC
A documentary letter of credit (documentary LC or commercial LC) is the primary payment vehicle in a merchandise trade transaction. The exporter ships goods, presents shipping documents to their bank, and the issuing bank pays upon presentation of complying documents. The documentary LC is intended to be drawn upon as part of every transaction it covers.
Letter of credit financing refers to the broader practice of using LC instruments, including documentary LCs, to access pre- or post-shipment funding. Banks and trade finance providers advance funds against LC-backed receivables, allowing exporters to receive payment before the LC proceeds are actually collected from the issuing bank.

Frequently Asked Questions
A standby letter of credit (SBLC) is an irrevocable bank undertaking to pay a beneficiary if the applicant fails to perform a contractual or financial obligation. It is a secondary instrument, intended to remain undrawn, and is called upon only in the event of default by the applicant.
SBLC stands for standby letter of credit. It is a bank instrument issued via SWIFT MT760, governed by ISP98 or UCP600, that provides a payment guarantee to a beneficiary in the event of the applicant's default. SBLCs are used in trade, project finance, real estate, and structured finance transactions.
A standby letter of credit and a bank guarantee serve the same economic purpose: both provide a beneficiary with a bank-backed undertaking to pay in the event of the applicant's default. The key difference is governing rules: SBLCs are subject to ISP98 or UCP600, while demand guarantees are subject to URDG 758. SBLCs are more common in US and Asian markets; demand guarantees are more common in European and Middle Eastern markets.
SBLC finance refers to the use of a standby letter of credit as a financial instrument to support a transaction or access funding. This includes using an SBLC as collateral for a loan, as security in a trade transaction, or as a monetisation instrument through which the SBLC holder accesses cash from a financier.
SBLC monetisation is the process of using an SBLC as collateral to obtain a cash advance from a lender or financier. The lender advances a percentage of the SBLC face value, typically 60% to 90%, with the SBLC serving as security. The advance is repaid from the borrower's project proceeds or other sources by the time the SBLC expires.
An SBLC provider is a bank or financial institution that issues standby letters of credit on behalf of applicants. Rated commercial banks are the most common providers. Arrangers such as Financely act as intermediaries, sourcing the issuing bank, structuring the instrument, and coordinating the SWIFT MT760 transmission on behalf of clients who require an SBLC.
MT760 is the SWIFT message format used to transmit standby letters of credit and bank guarantees between banks. When a bank issues an SBLC, it sends an authenticated MT760 message via the SWIFT network to the beneficiary's bank, which then notifies the beneficiary that the instrument has been issued in their favour. MT760 is the standard delivery mechanism for SBLCs in international banking.
A documentary letter of credit is a primary payment instrument in merchandise trade, governed by UCP600. The issuing bank undertakes to pay the exporter upon presentation of complying shipping and trade documents. Unlike an SBLC, a documentary LC is intended to be drawn upon as part of every transaction it covers.
Letter of credit financing refers to the use of LC instruments to access pre- or post-shipment funding. Banks and trade finance providers advance funds against LC-backed receivables or provide pre-shipment loans supported by an LC, allowing exporters to receive early payment and importers to extend their payment terms.
The main risks in SBLC transactions include fraudulent instruments issued by unrated or non-existent banks, scam intermediaries charging upfront fees before an instrument is delivered, and instruments that do not conform to ISP98 or UCP600. Legitimate SBLCs are issued by rated banks via authenticated SWIFT MT760 and can be verified directly with the issuing bank. Any arrangement requiring cash payment before delivery of a bank-authenticated instrument should be treated as a fraud risk.
