Bank Guarantees, SBLCs and Letters of Credit: How Each Instrument Works and When to Use One

Bank guarantees, standby letters of credit, documentary letters of credit, and related SWIFT instruments are the foundation of international trade finance. Each serves a different purpose, operates under different rules, and carries different implications for both the applicant and the beneficiary. This guide sets out how each instrument works, compares them directly, and explains how Financely helps clients access, structure, and where relevant monetise bank instruments from prime-rated issuers.

What is a Bank Guarantee?

Bank Guarantee (BG)

A bank guarantee is an unconditional undertaking issued by a bank on behalf of its client (the applicant) to pay a specified sum to a third party (the beneficiary) if the applicant fails to fulfil a contractual obligation. Unlike a loan, the bank guarantee does not transfer funds at the time of issuance. It is a contingent liability that only crystallises if a compliant demand is made by the beneficiary under the terms of the guarantee.

Bank guarantees are governed primarily by the ICC Uniform Rules for Demand Guarantees (URDG 758), published by the International Chamber of Commerce. They are used extensively in construction, commodities, infrastructure, and cross-border trade where a counterparty needs assurance of performance or payment before committing to a contract.

Types of Bank Guarantee

The term bank guarantee covers several distinct structures, each suited to a different commercial situation.

01

Performance Guarantee

Guarantees that a contractor or supplier will complete a project or deliver goods to specification. If they default, the beneficiary can call the guarantee for compensation.

02

Payment Guarantee

Assures a seller or creditor that the buyer will make payment on time. Commonly used in commodity supply agreements and deferred payment arrangements.

03

Advance Payment Guarantee

Protects a buyer who has made an advance payment to a supplier, ensuring the advance is returned if the supplier fails to deliver.

04

Bid Bond / Tender Guarantee

Required in procurement and public tenders. It guarantees that a bidder, if awarded the contract, will enter into the agreement and provide the required performance security.

05

Financial Guarantee

Supports a borrower's debt obligation. Used to satisfy a lender's requirement for credit support without the borrower needing to pledge physical assets.

06

Customs and Tax Guarantee

Issued to customs authorities or tax bodies as security for duties, taxes, or other regulatory obligations, often required for temporary import of goods.

How a Bank Guarantee is Issued and Transmitted

The applicant instructs their bank to issue a guarantee in favour of the beneficiary. The issuing bank either delivers the guarantee directly or, in cross-border transactions, transmits it via SWIFT using the MT760 message format. The MT760 is the standardised SWIFT instruction for the issuance of a guarantee or standby letter of credit and is the mechanism that authenticates the undertaking in the eyes of receiving banks and beneficiaries worldwide.

Not all banks will issue guarantees for all clients. The applicant typically needs an existing credit relationship with the issuing bank, or must provide cash collateral, blocked funds, or an alternative credit facility to back the issuance. Financely works with prime-rated correspondent banks to arrange guarantee issuance for clients who do not have a direct relationship with a top-tier issuer.

URDG 758 vs UCP 600: Bank guarantees issued under URDG 758 are demand guarantees, meaning they are payable on a compliant written demand without requiring the beneficiary to prove the applicant's default. This makes them more powerful than suretyship guarantees and is the standard in international transactions.

What is a Standby Letter of Credit (SBLC)?

Standby Letter of Credit (SBLC)

A standby letter of credit is a bank-issued financial guarantee that functions as a payment instrument of last resort. It tells a beneficiary: if the applicant fails to pay or perform as agreed, you may present the required documents to this bank and receive payment. Unlike a documentary letter of credit, which is the primary mechanism for payment in a trade transaction, an SBLC sits in reserve and is only called upon if the underlying contract breaks down.

SBLCs are governed either by the ICC Uniform Customs and Practice for Documentary Credits (UCP 600) or by the International Standby Practices (ISP98), depending on how they are structured. US banks typically issue SBLCs because US banking law historically restricted banks from issuing guarantees, making the SBLC a functional equivalent structured as a letter of credit rather than a guarantee.

SBLC Monetisation

A key feature that distinguishes SBLCs from standard letters of credit is that they can be monetised. SBLC monetisation is the process of converting the credit value of a bank instrument into liquid funds, typically through a lending facility from a monetisation bank that advances a percentage of the instrument's face value. This allows the beneficiary or instrument holder to access working capital without calling the SBLC or triggering a default claim.

Monetisation Step What Happens
1. Instrument issuance The applicant's bank issues the SBLC via MT760 and transmits it to the beneficiary's bank.
2. Verification The receiving bank verifies the instrument's authenticity and confirms the issuing bank's standing. Only prime-rated bank instruments are accepted for monetisation.
3. Credit facility The monetisation bank advances a percentage of the SBLC's face value, typically 60 to 80%, against the instrument as security.
4. Repayment The facility is repaid at or before the SBLC's expiry. If the underlying project generates returns, those are used to repay the monetisation facility.

Caution on SBLC monetisation: A significant volume of SBLC monetisation enquiries involves fraudulent instruments or fictitious providers. Financely only works with prime-rated issuing banks whose instruments can be verified directly via SWIFT. No fee should ever be paid upfront to a provider claiming they can monetise an instrument before issuance is confirmed.

SBLC Providers, Lenders and Issuance

Legitimate SBLC providers are regulated banks with top-tier credit ratings. The term "SBLC providers" in the market can refer either to the issuing bank itself or to intermediaries who arrange access to issuance capacity at such banks. Similarly, SBLC lenders are institutions that advance funds against an SBLC held as security, distinct from the issuing bank. Financely acts as an arranger: we work with our network of prime bank correspondents to facilitate SBLC issuance for clients who require the instrument but do not have a direct facility with an eligible issuer. Instruments are issued at face value from rated institutions, transmitted via MT760, and meet the documentary requirements of any receiving bank or beneficiary in a standard trade or finance transaction.

Bank guarantee providers operate in a comparable way. A provider may be the issuing bank directly, or an arranger with access to issuance lines at prime banks. The key distinction when evaluating bank guarantee providers or SBLC providers is whether they can demonstrate a direct relationship with a rated issuing institution and whether the instrument, once issued, will be transmitted via authenticated MT760 to the beneficiary's bank. International trade finance instruments including BGs and SBLCs that cannot meet this standard are of no commercial value regardless of the documentation accompanying them.

What is a Documentary Letter of Credit (DLC)?

Documentary Letter of Credit (DLC)

A documentary letter of credit is a bank's undertaking to pay a seller a specified amount upon presentation of stipulated documents proving that goods have been shipped or services delivered in accordance with the terms of the credit. Unlike a bank guarantee or SBLC, a documentary LC is not a security instrument held in reserve. It is the primary payment mechanism for the trade transaction and is expected to be called in the ordinary course of business.

All documentary letters of credit issued under international rules are governed by UCP 600. The rules set out precisely what the issuing bank, confirming bank, and presenting bank must do when documents are presented, and they define what constitutes a complying presentation. Non-compliance with documentary requirements, such as a discrepancy in the bill of lading or an incorrect description of goods, is the most common cause of payment delay or refusal under a documentary LC.

DLC vs SBLC: Key Differences

The documentary LC and the SBLC are frequently confused because both are letters of credit and both reference UCP 600. The functional distinction is significant.

Feature Documentary LC (DLC) Standby LC (SBLC)
Primary purpose Payment for goods or services in the normal course of trade Security instrument used only if the applicant defaults
When called Routinely, on compliant presentation of shipping documents Only on applicant's failure to pay or perform
Documents required Full set of trade documents: bill of lading, commercial invoice, packing list, inspection certificate etc. Usually a simple demand statement and a copy of the underlying invoice or agreement
Governing rules UCP 600 ISP98 or UCP 600
Monetisable Not typically used as a financial instrument Yes, under a monetisation facility
Used in Import / export payment, commodity trades, manufacturing supply chains Project finance, real estate, energy, regulated industries

Bank Guarantee vs SBLC: What is the Difference?

The bank guarantee and the standby letter of credit are economically equivalent instruments: both are issued by a bank to assure a beneficiary that payment will be made if the applicant defaults. The practical differences lie in their legal form, governing rules, documentary requirements on a call, and the jurisdiction and type of bank most likely to issue them.

Feature Bank Guarantee (BG) Standby LC (SBLC)
Legal form Independent guarantee or suretyship Letter of credit structured as a standby
Primary rules ICC URDG 758 ISP98 or UCP 600
Common issuers European, Middle Eastern and Asian banks US banks and international institutions
SWIFT message MT760 MT760
Demand requirement Simple written demand under URDG 758 Presentation of specified documents
Monetisable Yes, subject to issuer and instrument quality Yes, widely accepted for monetisation
Counter-guarantee Common in indirect guarantee structures Less common; confirmed LC used instead

In practice, a beneficiary in a European construction contract will typically receive a bank guarantee under URDG 758, while a US real estate or energy project will more often use an SBLC governed by ISP98. For the purposes of SWIFT transmission and cross-border acceptability, both instruments are transmitted via MT760 and are treated comparably by receiving banks and monetisation providers.

What is MT760 and How Does It Work?

MT760 is the SWIFT message type used by banks to issue or request the issuance of a guarantee or standby letter of credit. When a bank transmits an MT760, it is sending an authenticated, bank-to-bank message confirming that it has issued the instrument and bears the obligation described. Receipt of an MT760 by the beneficiary's bank is the standard method of confirming that a bank instrument is genuine and in force.

The MT760 format has defined fields covering the transaction reference, form of undertaking, currency and amount, expiry date, applicable rules, and the text of the undertaking itself. Instruments that have not been transmitted via authenticated SWIFT are not generally accepted in international trade transactions. Claims that a bank guarantee or SBLC has been "issued" but not yet transmitted, or that transmission will only occur after payment of an advance fee, are characteristic of instrument fraud.

MT760 vs MT700: MT700 is the SWIFT message type for the issuance of a documentary letter of credit (DLC or commercial LC). MT760 is used specifically for guarantees and standby credits. Both are authenticated bank-to-bank messages, but they carry different instrument types and operate under different rules.

Bank Guarantee and SBLC Costs

The cost of a bank guarantee or SBLC is expressed as an annual percentage of the instrument's face value. The exact rate depends on the issuing bank, the applicant's creditworthiness, the instrument type, the term, and the sector. The following ranges reflect standard market pricing for prime bank issuance.

Cost Component Typical Range Notes
Annual issuance fee 1% to 3% per annum Charged on the face value of the instrument by the issuing bank
Swift/handling charge $500 to $2,500 flat One-off bank charge for MT760 transmission and documentation
Collateral requirement 100% cash, or credit line equivalent Issuing bank requires security; Financely's process minimises this for qualifying clients
Arranger fee (Financely) Agreed on engagement Payable on successful issuance only, not upfront
Confirmation fee 0.5% to 1.5% per annum additional If the beneficiary requires a confirming bank to add its own undertaking

No upfront fees: Legitimate bank guarantee and SBLC providers do not charge advance fees before instrument issuance. Financely's arranger fee is structured to be payable on completion. Any provider demanding payment before a genuine MT760 has been transmitted and verified by the beneficiary's bank should be treated with the highest degree of caution.

Frequently Asked Questions

Both are conditional undertakings by a bank to pay a beneficiary if the applicant defaults. The bank guarantee is typically governed by URDG 758 and issued by European, Middle Eastern, or Asian banks. The SBLC is structured as a letter of credit, usually under ISP98 or UCP 600, and is more common with US and international banks. Both are transmitted via MT760. Economically they achieve the same result; the distinction matters for the applicable rules, documentary requirements on a demand, and which institutions will accept them.

A documentary letter of credit is the primary payment mechanism for a trade transaction. It is expected to be called in the normal course of business when the seller presents compliant shipping documents. An SBLC is a contingent instrument: it sits in reserve and is only called if the applicant fails to pay or perform. The documentary LC requires a full set of trade documents on presentation; the SBLC typically requires only a simple demand statement and, sometimes, a copy of the unpaid invoice.

In common usage, DLC (documentary letter of credit) and LC (letter of credit) refer to the same instrument: a bank's commitment to pay a seller against presentation of compliant trade documents under UCP 600. The term "documentary" simply emphasises that payment is conditional on presenting specified documents such as a bill of lading, commercial invoice, and certificate of origin. Both terms describe the same product; DLC is sometimes used to distinguish documentary credits from standby credits (SBLCs).

Yes, subject to the quality of the instrument. Bank guarantees and SBLCs issued by prime-rated banks and transmitted via authenticated MT760 can be monetised through a lending facility from a monetisation counterparty. The facility advances a percentage of the instrument's face value, typically 60 to 80%, with the instrument serving as security. Instruments from unrated or non-prime banks are generally not accepted for monetisation. The process requires verification of the issuing bank's standing and confirmation that the MT760 has been transmitted cleanly.

MT760 is the specific SWIFT message type used to issue or transmit a bank guarantee or standby letter of credit from one bank to another. It is an authenticated, bank-to-bank communication and is the internationally accepted method of confirming that a bank instrument is genuine and has been formally issued. An instrument that has not been transmitted via MT760 is not considered valid in most international trade and finance contexts. The number "760" refers to the SWIFT field structure for guarantee and standby credit issuance, distinct from MT700 which is used for documentary credits.

SBLC funding typically refers to using an SBLC as collateral to secure a credit facility or project funding line. The SBLC is pledged to a lender, who advances funds against it as security. SBLC monetisation is a specific form of this where the instrument is immediately converted to cash through a structured lending arrangement, usually at 60 to 80 cents on the dollar. The terminology is used interchangeably in the market, but the underlying mechanics are the same: the SBLC's credit value substitutes for physical collateral in a lending transaction.

Prime-rated commercial banks, typically those with investment-grade credit ratings from Moody's, S&P, or Fitch, are the accepted issuers for SBLCs and bank guarantees used in international trade and monetisation. This includes the major US, European, and Asian clearing banks. Non-prime or unrated institutions may issue instruments, but these are generally not accepted by beneficiaries for security purposes, by lenders for monetisation, or by counterparties in structured finance transactions. Financely's network covers issuance through rated prime bank correspondents in multiple jurisdictions.

A genuine bank instrument should be verifiable through the receiving bank's SWIFT department. Once an MT760 has been transmitted, the beneficiary's bank can confirm receipt through its SWIFT infrastructure. Instruments that cannot be verified by authenticated SWIFT, that are presented only as PDF or paper documents without a corresponding MT760, or that come from banks that cannot be independently verified as rated prime institutions should be treated as suspect. If in doubt, the beneficiary should instruct their own bank to confirm the instrument directly with the issuing bank via SWIFT before relying on it for any commercial or financial purpose.
