Introduction

A Letter of Credit reduces payment risk in international trade by replacing, to a significant extent, the buyer's payment promise with an independent undertaking of a bank.

However, an LC does not eliminate all risks.

Different parties may still face:

  • credit risk;

  • documentary risk;

  • country and political risk;

  • fraud risk;

  • operational risk;

  • foreign-exchange risk;

  • reimbursement risk; and

  • compliance or sanctions-related risk.

Effective LC management therefore requires both a sound understanding of UCP 600 and strong operational safeguards.

This topic also links three important areas:

  • Standby Letter of Credit (SBLC) – an undertaking generally used as a secondary payment or performance support;

  • URR 725 – ICC rules for bank-to-bank reimbursement under documentary credits; and

  • ISBP – international standard banking practice used in examining documents under UCP 600.

An important current-position point is that ISBP 745, issued in 2013, is no longer the latest edition. ICC published ISBP 821 in 2023, which is now the most up-to-date guide for document examination under UCP 600.

Learning Objectives

After studying this topic, you should be able to:

  • Identify the major risks faced by parties to an LC.

  • Explain practical safeguards against documentary, credit and operational risks.

  • Distinguish a commercial LC from a Standby LC.

  • Understand the purpose and operation of URR 725.

  • Explain the relationship between UCP 600 and ISBP.

  • Recognise the current relevance of ISBP 821 in place of the older ISBP 745.

Why an LC Does Not Remove Every Risk

An LC creates an independent documentary undertaking, but the transaction still involves several parties, jurisdictions, documents and payment mechanisms.

For example:

  • the importer may fail financially;

  • the issuing bank may face country restrictions;

  • the exporter may present discrepant documents;

  • forged documents may be presented;

  • reimbursement instructions may be defective;

  • exchange rates may move adversely; or

  • operational errors may occur during issuance, amendment, scrutiny or payment.

Therefore, LC risk management must be considered from the perspective of each party.

Major Risks in a Documentary Credit

1. Applicant or Importer Risk

The applicant requests the bank to issue the LC and ultimately has to reimburse the issuing bank.

The issuing bank therefore faces the risk that the applicant may:

  • become financially weak;

  • fail to provide funds when payment falls due;

  • dispute the underlying transaction;

  • exceed sanctioned limits; or

  • become unable to meet a foreign-currency liability.

Safeguards

The issuing bank may use:

  • proper credit appraisal;

  • sanctioned LC limits;

  • margin or collateral where appropriate;

  • monitoring of outstanding and devolved LCs;

  • assessment of the underlying trade transaction;

  • customer due diligence; and

  • foreign-exchange risk management where relevant.

2. Issuing Bank Risk

The beneficiary relies primarily on the issuing bank's undertaking.

The beneficiary may therefore face risk arising from:

  • deterioration in the issuing bank's financial position;

  • restrictions in the issuing bank's country;

  • transfer or currency controls;

  • political instability; or

  • inability to remit funds across borders.

Safeguard: Confirmation

Where acceptable and commercially justified, a beneficiary may seek an LC confirmed by another bank.

A confirming bank adds its own undertaking to that of the issuing bank under UCP 600.

This can reduce the beneficiary's exposure to:

  • issuing-bank risk; and

  • certain country or transfer risks,

subject to the terms of the confirmation and applicable law.

Confirmation, however, creates risk for the confirming bank, which must assess the issuing bank and country before adding its undertaking.

3. Documentary Risk

This is one of the most important LC risks.

The beneficiary may ship the goods correctly but still fail to obtain payment because the documents do not comply with the LC.

Typical causes include:

  • late shipment;

  • late presentation;

  • inconsistent data;

  • incorrect transport documents;

  • inadequate insurance documents;

  • missing certificates;

  • incorrect issuer of a required document; or

  • failure to comply with an LC condition.

The bank examines documents rather than the actual goods. UCP 600 defines a complying presentation by reference to the terms of the credit, applicable UCP provisions and international standard banking practice.

Safeguards

The beneficiary should:

  • review the LC immediately after receipt;

  • request amendments before shipment where necessary;

  • understand documentary requirements clearly;

  • avoid unnecessary conditions and documents;

  • coordinate with carriers, insurers and inspection agencies;

  • prepare documents consistently; and

  • present documents early enough to allow correction where possible.

The issuing bank should draft the LC clearly and avoid unnecessary or ambiguous documentary requirements.

4. Fraud and Forgery Risk

Because banks deal in documents, there remains a risk that a document may be:

  • forged;

  • fraudulently altered;

  • issued in connection with a fictitious transaction; or

  • used to misrepresent the underlying facts.

Normal documentary examination does not amount to physical verification of goods.

Safeguards

Banks should maintain strong controls relating to:

  • customer due diligence;

  • transaction monitoring;

  • authentication of interbank messages;

  • unusual transaction patterns;

  • document examination;

  • escalation of suspicious transactions; and

  • applicable fraud, sanctions and anti-money-laundering requirements.

5. Country, Political and Transfer Risk

International trade may involve jurisdictions exposed to:

  • war;

  • political instability;

  • exchange controls;

  • restrictions on remittances;

  • sovereign actions;

  • sanctions; or

  • disruption of banking systems.

Such events can interfere with settlement even where the commercial parties remain financially sound.

Safeguards

Depending on the transaction, safeguards may include:

  • country exposure limits;

  • confirmation;

  • suitable risk participation;

  • appropriate insurance;

  • careful choice of banks and jurisdictions; and

  • compliance screening before issuance and payment.

6. Foreign-Exchange Risk

The LC may be denominated in a currency different from the applicant's or beneficiary's domestic currency.

Exchange-rate changes between:

  • order date;

  • shipment date;

  • presentation date; and

  • settlement date

may change the domestic-currency value of the transaction.

Safeguard

Where appropriate, the party exposed to currency risk may hedge through permitted foreign-exchange instruments according to applicable regulations and bank policy.

7. Operational Risk

LC transactions involve multiple processes:

  • issuance;

  • advising;

  • confirmation;

  • amendment;

  • document presentation;

  • examination;

  • refusal;

  • reimbursement; and

  • settlement.

Errors may arise from:

  • incorrect LC drafting;

  • missed deadlines;

  • wrong amendment processing;

  • incomplete discrepancy notices;

  • incorrect reimbursement instructions;

  • duplicate payments; or

  • unauthorised messaging.

Safeguards

Banks should maintain:

  • maker-checker controls;

  • authenticated communication;

  • diary and deadline controls;

  • standardised scrutiny procedures;

  • proper authorisation limits;

  • reconciliation controls; and

  • trained trade-finance staff.

Effective LC risk management combines credit assessment, documentary discipline, controls and appropriate risk mitigation.

Standby Letter of Credit

A Standby Letter of Credit is an independent undertaking generally intended to support an obligation if the applicant fails to pay or perform as required.

Unlike a normal commercial LC, which is ordinarily expected to be drawn when the trade transaction proceeds normally, a standby is commonly expected to remain undrawn unless a specified default or non-performance occurs.

ICC guidance describes a standby as an independent documentary undertaking, and ISP98 states that a standby is irrevocable, independent, documentary and binding when issued.

Common Uses

Standbys can support obligations such as:

  • repayment of financial obligations;

  • payment for goods or services;

  • performance of contractual obligations; or

  • other agreed payment or performance commitments.

Common Rule Framework

UCP 600

ISP98 or, where stated and applicable, UCP 600

UCP 600 Article 1 expressly allows UCP 600 to apply to standby letters of credit to the extent to which the rules may be applicable, where the standby expressly incorporates UCP 600. However, ISP98 was specifically designed for standby letters of credit and provides a dedicated framework for their distinctive features.

URR 725: Bank-to-Bank Reimbursement

URR 725 means the ICC Uniform Rules for Bank-to-Bank Reimbursements under Documentary Credits.

They became effective on 1 October 2008 and were aligned in style with UCP 600.

Their purpose is to provide a clear framework where a bank that honours or negotiates under an LC seeks reimbursement through another bank.

Main Parties

Under URR 725:

  • Issuing Bank – issues the credit and reimbursement authorization.

  • Reimbursing Bank – is instructed or authorised to provide reimbursement.

  • Claiming Bank – the bank that honours or negotiates and submits the reimbursement claim.

When Does URR 725 Apply?

URR 725 does not apply automatically merely because an LC uses another bank for reimbursement.

Article 1 provides that URR 725 applies when the reimbursement authorization expressly indicates that it is subject to those rules. The issuing bank is responsible for indicating in the credit that reimbursement is subject to URR 725.

This is an important CAIIB distinction.

If reimbursement is not subject to URR 725, UCP 600 Article 13 provides the relevant basic reimbursement framework where applicable.

Reimbursement Authorization Is Separate from the LC

Under URR 725 Article 3, the reimbursement authorization is separate from the documentary credit.

The reimbursing bank is not concerned with or bound by the terms and conditions of the LC merely because the authorization refers to it.

This mirrors an important documentary-credit principle: different undertakings in the transaction must not be confused.

Does the Reimbursing Bank Examine LC Documents?

No.

Its function is reimbursement according to the reimbursement authorization or any reimbursement undertaking it has issued.

URR 725 specifically prevents the reimbursement process from being converted into a second examination of the underlying LC documents.

For example, the issuing bank must not require a certificate of compliance with the LC terms in the reimbursement authorization.

Reimbursement Authorization vs Reimbursement Undertaking

These two concepts are frequently confused.

A reimbursement authorization is an instruction or authority from the issuing bank to the reimbursing bank.

A reimbursement undertaking is a separate irrevocable undertaking issued by the reimbursing bank to the named claiming bank.

Once the reimbursing bank issues such a reimbursement undertaking, it is irrevocably bound to honour a complying reimbursement claim under that undertaking.

Processing Time

URR 725 provides the reimbursing bank a maximum of three banking days following the day of receipt of a reimbursement claim to process the claim. Where it decides not to reimburse, the applicable notice requirement must also be observed.

ISBP 745 and the Current ISBP 821

The subtopic refers to ISBP 745, which is important historically but requires a current-position clarification.

The development has been:

  • ISBP 645 – first approved in 2002;

  • ISBP 681 – issued in 2007;

  • ISBP 745 – issued in 2013; and

  • ISBP 821 – issued in 2023.

ICC confirms that the 2023 edition, ISBP 821, resulted from a review of ISBP 745 and is the current, most up-to-date guide for examination of documentary-credit documents under UCP 600.

What Does ISBP Do?

ISBP provides detailed international banking practice for examining documents under UCP 600.

It helps practitioners apply UCP principles to matters such as:

  • signatures;

  • dates;

  • corrections and alterations;

  • drafts and maturity;

  • invoices;

  • multimodal transport documents;

  • bills of lading;

  • air transport documents;

  • insurance documents;

  • certificates of origin;

  • packing and weight lists; and

  • other certificates.

ICC describes ISBP 821 as a guide that should be read in conjunction with UCP 600.

ISBP therefore does not replace UCP 600. It helps explain how international standard banking practice is applied during document examination.

How the ICC Framework Fits Together

For exam purposes, distinguish the purpose of each framework:

Framework

Main Purpose

UCP 600

Core rules governing documentary credits expressly subject to UCP

ISBP 821

Detailed banking practice for examination of documents under UCP 600

URR 725

Bank-to-bank reimbursement under documentary credits when expressly incorporated

ISP98

Rules specifically designed for Standby Letters of Credit

These instruments are related, but they are not interchangeable.

Practical Banking Application

Consider an importer whose bank issues a commercial LC in favour of an overseas exporter.

The issuing bank may face:

  • applicant credit risk;

  • country and transfer risk;

  • documentary-processing risk; and

  • reimbursement risk.

The exporter may face:

  • issuing-bank risk; and

  • risk of presenting discrepant documents.

A sound transaction may therefore involve:

  1. proper appraisal and LC limits for the applicant;

  2. clear LC drafting;

  3. confirmation where appropriate;

  4. careful preparation and scrutiny of documents using UCP 600 and current ISBP 821;

  5. authenticated and controlled interbank communication; and

  6. properly structured reimbursement instructions, including URR 725 where expressly incorporated.

If instead the requirement is merely to support payment or performance if the applicant defaults, a Standby LC governed by an appropriate rule framework may be more suitable than a conventional commercial documentary credit.

CAIIB Exam Focus

Remember these high-value concepts:

  • An LC reduces risk but does not eliminate all commercial, credit, documentary and operational risks.

  • Confirmation adds the confirming bank's own undertaking and can mitigate issuing-bank and certain country risks for the beneficiary.

  • Banks examine documents rather than the actual goods.

  • A Standby LC is generally a secondary support mechanism rather than the normal primary trade-payment mechanism.

  • UCP 600 can apply to standbys to the extent applicable when expressly incorporated.

  • ISP98 is specifically designed for Standby LCs.

  • URR 725 governs bank-to-bank reimbursement, not examination of the commercial documents.

  • URR 725 applies when the reimbursement authorization expressly incorporates it.

  • The reimbursement authorization is separate from the LC.

  • A reimbursement undertaking is different from a mere reimbursement authorization.

  • ISBP 745 is the 2013 edition; ISBP 821 (2023) is the current edition.

  • ISBP assists in applying document-examination practice and does not replace UCP 600.

Common Exam Traps

Trap 1: “An LC Eliminates All Risk”

Incorrect.

It primarily provides an independent bank undertaking subject to complying presentation. Credit, country, documentary, operational and fraud risks can still remain.

Trap 2: “Commercial LC and Standby LC Operate for the Same Primary Purpose”

Incorrect.

A commercial LC normally functions as a primary trade-payment mechanism. A standby usually supports payment or performance if the applicant does not fulfil the supported obligation.

Trap 3: “Every Standby LC Is Automatically Governed by ISP98”

Incorrect.

The applicable rules depend on what the standby incorporates.

Trap 4: “URR 725 Automatically Applies Whenever a Reimbursing Bank Is Used”

Incorrect.

The reimbursement authorization must expressly indicate that it is subject to URR 725.

Trap 5: “The Reimbursing Bank Must Check Whether LC Documents Comply”

Incorrect.

The reimbursement authorization is separate from the LC, and the reimbursing bank is not concerned with the LC's terms and conditions merely because they are referenced.

Trap 6: “Reimbursement Authorization and Reimbursement Undertaking Are the Same”

Incorrect.

The authorization comes from the issuing bank. The undertaking is a separate irrevocable commitment of the reimbursing bank to the claiming bank when issued under URR 725.

Trap 7: “ISBP 745 Is the Latest ISBP”

Incorrect under the current ICC framework.

ISBP 745 was published in 2013. ISBP 821, published in 2023, is the current edition.

Memory Technique

Remember R-S-R-I:

  • R – Risks: identify credit, documentary, country, fraud, FX and operational risks.

  • S – Safeguards: appraisal, confirmation, clear drafting, scrutiny, hedging and controls.

  • R – Reimbursement: URR 725 governs the separate bank-to-bank reimbursement mechanism.

  • I – ISBP: use current ISBP 821 with UCP 600 for document-examination practice.
