Standby Letter of Credit · trade-finance
A Standby Letter of Credit (SBLC) is a written undertaking with the nature of an independent guarantee, issued by a bank or other financial institution at the request of an applicant. When the applicant fails to fulfill its obligations under the underlying contract, the beneficiary may claim against the issuing bank by presenting documents complying with the terms of the SBLC. Its fundamental difference from a commercial letter of credit is that a commercial letter of credit is a "performance payment instrument," while an SBLC is a "default compensation instrument."
From a legal origin perspective, the SBLC was born in the United States. Because U.S. law long prohibited domestic banks from issuing guarantees (bank guarantees), the U.S. banking industry created this instrument that "takes the form of a letter of credit but is substantively a guarantee." The United Nations Convention on Independent Guarantees and Stand-by Letters of Credit, adopted by the UN General Assembly in 1995, and the International Chamber of Commerce's International Standby Practices (ISP98, effective 1998) provide unified international rules for SBLCs. Article 1.01 of ISP98 explicitly states: ISP98 applies to any standby letter of credit or similar independent undertaking, including counter-guarantees, confirmations, etc.
In the overseas engineering practice of Chinese enterprises, SBLCs mainly play three roles:
Compared with Demand Guarantees, SBLCs are more widely accepted in common law countries (especially the United States, the United Kingdom, Australia, and Singapore), because banks and courts in these countries are more familiar with the letter of credit system. In regions such as the Middle East and Africa, demand guarantees are more common.
Key Legal Characteristics:
| Element | Description | Typical Data/Range | Notes |
|---|---|---|---|
| **Amount** | Guarantee amount, usually 5%–20% of the underlying contract amount | Performance guarantee: 10%–15%; Advance payment guarantee: equal to advance payment; Quality guarantee: 5%–10% | Need to specify currency, whether interest is included, whether automatic reduction applies |
| **Tenor** | From issuance date to expiry date | Performance: contract period + 90–180 days; Advance payment: until advance payment is fully deducted; Quality: defects liability period + 30–90 days | Expiry date must be specified as a "fixed date" or "event-triggered" |
| **Fee Rate** | Guarantee fee charged by the issuing bank | Annualized 0.5%–2.5% (depending on country, corporate credit, guarantee method) | Middle East/Africa high-risk countries can reach 2%–3%; Chinese banks may offer 0.3%–0.8% for central SOEs |
| **Applicable Scenarios** | Situations requiring bank credit to replace commercial credit | Overseas engineering bidding, performance, advance payment, quality assurance, payment guarantee | U.S./U.K./Singapore projects prefer SBLC; Middle East/Africa may use guarantees |
| **Issuing Bank** | Usually the bank in the applicant's location | Chinese banks (Bank of China, ICBC, CCB, etc.), international banks (HSBC, Standard Chartered, Citibank) | Need to confirm whether the employer accepts direct issuance by Chinese banks; otherwise, counter-issuance is needed |
| **Advising/Reissuing Bank** | Bank in the beneficiary's location | Local bank or local branch of an international bank | Reissuance fee typically 0.1%–0.5%/year, increasing total cost |
| **Confirmation** | Additional guarantee by a third-party bank | Confirmation fee 0.1%–0.3%/year | Employers in high-risk countries may require confirmation |
| **Claim Conditions** | Documents required for the beneficiary to claim | Typically: claim statement + default certificate + draft | Need to specify whether "payable on demand" or "conditional claim" is required |
| **Applicable Rules** | Governing law | ISP98, UCP600, local law | Recommend specifying ISP98 to avoid legal ambiguity |
Amount Reduction Mechanism: In advance payment guarantees, the SBLC amount typically decreases as the advance payment is deducted. For example, if the advance payment is 15% of the contract amount and is deducted over 10 installments, the SBLC amount decreases by 1.5% per installment. The reduction method must be specified in the SBLC (automatic reduction upon the contractor's submission of deduction certificates, or requiring employer confirmation).
Expiry Date Design: A common pitfall in overseas engineering is that "the expiry date is earlier than the actual completion date." It is recommended that the performance SBLC expiry date = contract period + 180 days, with an "Evergreen Clause" providing that if no notice of non-extension is received from the employer 30 days before expiry, it automatically extends for one year. However, note that some countries' laws do not recognize automatic extension, so this must be confirmed in advance.
| Step | Time | Description |
|---|---|---|
| Credit Approval | 2–6 weeks | Central SOEs/state-owned enterprises go through internal credit procedures; new clients need to provide financial statements, project contracts, etc. |
| SBLC Issuance | 3–10 business days | After documents are complete, the bank reviews terms and issues |
| Reissuance | Additional 5–15 business days | Reissuing bank needs to review and charge fees |
| Confirmation | Additional 3–10 business days | Confirming bank review |
| Amendment/Extension | 3–7 business days | Requires confirmation from both banks |
Total Cycle: Direct issuance approximately 3–6 weeks; reissuance approximately 6–10 weeks. It is recommended to initiate bank procedures 60 days before contract signing.

Bank Review Focus:
Common Document Checklist (taking a Bank of China overseas project as an example):
Background: In 2018, CNPC Pipeline Bureau won an EPC contract for a natural gas pipeline project in Kazakhstan, with a contract value of approximately USD 280 million and a construction period of 24 months. The employer was KazMunayGas (KMG), which required the contractor to provide a performance guarantee of 10% of the contract amount, i.e., USD 28 million.
Solution: Since KMG only accepted SBLCs issued directly by local Kazakh banks or international banks, CNPC Pipeline Bureau issued an SBLC through Bank of China to Halyk Bank of Kazakhstan, which then reissued it to KMG. The SBLC terms applied ISP98, with an expiry date of construction period + 180 days, and the amount gradually decreased with project progress (25% reduction per quarter).
Costs: Bank of China issuance fee 0.6% annualized, Halyk Bank reissuance fee 0.4% annualized, total cost approximately 1.0%/year. USD 28 million × 1.0% × 2.5 years = USD 700,000.
Result: The project was completed on schedule with no claims. The SBLC automatically expired after the defects liability period ended. Key lesson: Confirm the list of banks acceptable to the employer in advance to avoid rejection of the reissuing bank.
Background: In 2019, CCECC won a railway project in Nigeria with a contract value of approximately USD 1.5 billion, and the advance payment was 15% of the contract amount (USD 225 million). The employer, the Nigerian Ministry of Transportation, required the contractor to provide an advance payment SBLC of equal amount, and the SBLC needed to be reissued by a local Nigerian bank.
Solution: CCECC issued an SBLC through ICBC to First Bank of Nigeria, which then reissued it to the Nigerian Ministry of Transportation. The SBLC amount automatically decreased as the advance payment was deducted, with each deduction confirmed by the contractor's submission of deduction certificates. The SBLC applied ISP98, with an expiry date of 30 days after the advance payment was fully deducted.
Costs: ICBC issuance fee 0.5% annualized, First Bank reissuance fee 1.2% annualized (high Nigerian country risk premium), total cost approximately 1.7%/year. USD 225 million × 1.7% × 3 years = USD 11.475 million.
Risk Point: Nigeria has strict foreign exchange controls. If a claim occurs, the employer may require payment in naira, while the SBLC is denominated in USD, creating exchange rate risk. CCECC specified in the SBLC that "the claim payment currency is USD" and required the employer to confirm.
Result: During project execution, due to employer's land acquisition delays, the construction period was extended, and the SBLC was extended twice, with each extension costing approximately USD 50,000. The project was ultimately completed with no claims.
Background: In 2020, a Chinese central SOE constructed a coal-fired power plant in Indonesia with a contract value of approximately USD 800 million and a defects liability period of 24 months. The employer, PLN (Indonesia's state electricity company), required the contractor to provide a quality SBLC of 5% of the contract amount, i.e., USD 40 million, with a tenor of defects liability period + 90 days.
Solution: The central SOE issued an SBLC directly through China Construction Bank to PLN, applying ISP98. The SBLC terms explicitly stated: claims require submission of "a defect notice issued by the employer + proof that the contractor failed to remedy within 30 days." Since PLN accepted direct issuance by Chinese banks, no reissuance was needed, saving reissuance fees.
Costs: CCB issuance fee 0.7% annualized, total cost approximately USD 40 million × 0.7% × 2.25 years = USD 630,000.
Result: During the defects liability period, the employer raised 3 defects, all of which the contractor remedied within 30 days, and no claims were triggered. The SBLC automatically expired after the expiry date. Key lesson: The claim conditions of a quality SBLC should clearly state "notice first, claim later" to avoid direct claims by the employer.

Selection Recommendations:
Q1: What is the difference between an SBLC and a guarantee?
A: An SBLC is in the form of a letter of credit, governed by ISP98/UCP600; a guarantee is in the form of a suretyship, governed by local law. SBLCs have high acceptance in common law countries, while guarantees are more common in the Middle East/Africa.
Q2: What are the typical SBLC fees?
A: Annualized 0.5%–2.5%, depending on country, corporate credit, and guarantee method. Chinese banks may offer 0.3%–0.8% for central SOEs, and high-risk countries can reach 2%–3%.
Q3: Does an SBLC require credit occupation?
A: Yes, an SBLC occupies the enterprise's credit line at the bank. If credit is insufficient, a margin deposit or pledge is required.
Q4: Can an SBLC be transferred?
A: Yes, but a "transferable" clause must be specified in the SBLC. Transfer requires the issuing bank's consent, and transfer fees are borne by the applicant.
Q5: How is an SBLC cancelled after expiry?
A: It automatically expires after the expiry date, but it is recommended that the beneficiary issue a "cancellation confirmation letter" or return the original SBLC so the bank can release credit.
Q6: Can the employer claim directly?
A: If the SBLC is "payable on demand," the employer can claim solely upon the claim statement; if it is "conditional claim," a default certificate must be submitted. It is recommended to strive for conditional claims.
Q7: Can an SBLC be extended?
A: Yes, an extension must be applied for at the bank before expiry and consented to by the beneficiary. Extension fees are typically calculated proportionally to the original fee.
Q8: What law governs an SBLC?
A: It is recommended to apply ISP98 (International Standby Practices) or English law. Avoid applying the employer's country's law unless the enterprise is familiar with that country's law.
Q9: What is the relationship between SBLC and UCP600?
A: UCP600 mainly applies to commercial letters of credit but can also apply to SBLCs. ISP98 is a rule specifically formulated for SBLCs, and it is recommended to prioritize ISP98.
Q10: What happens after an SBLC is claimed?
A: The issuing bank will pay first and then seek reimbursement from the applicant. The applicant must immediately initiate dispute resolution procedures (such as arbitration) and apply for a stop-payment order (if applicable).
Q11: Does an SBLC need confirmation?
A: If the employer only accepts international bank credit, or the country risk is high, confirmation may be needed. Confirmation fees are typically 0.1%–0.3%/year.
Q12: Can an SBLC be amended?
A: Yes, but the beneficiary's consent is required. Amendments include amount, tenor, terms, etc. Amendment fees are borne by the applicant.
Q13: What is the difference between an SBLC and an advance payment guarantee?
A: An SBLC is in the form of a letter of credit, while an advance payment guarantee is in the form of a suretyship. Both have similar functions, but SBLCs are more easily accepted in common law countries.
Q14: Does an SBLC require a counter-guarantee?
A: Yes, banks typically require the applicant to provide a counter-guarantee, including margin deposits, pledges, parent company guarantees, etc.
Q15: How is an SBLC used under FIDIC contracts?
A: FIDIC contracts (such as the Silver Book) typically require the contractor to provide performance guarantees and advance payment guarantees. An SBLC can serve as a form of performance guarantee and must comply with FIDIC clause requirements.
