ISP98 is the ICC rule set designed for standby letters of credit, covering issuance, presentation, examination, dishonor, transfer, cancellation, and reimbursement.
The International Standby Practices, commonly called ISP98, are International Chamber of Commerce rules designed for standby letters of credit and similar independent undertakings that expressly incorporate them. ISP98 supplies standardized terms for issuance, presentation, examination, dishonor, transfer, cancellation, reimbursement, timing, and other standby operations. It is not legislation and does not govern a standby merely because the transaction is international.
ISP98 Rule 1.01 covers standby letters of credit, including performance, financial, and direct-pay standbys. A domestic or international undertaking with another name can also be made subject to ISP98 by express reference.
An effective review starts with the issued instrument. Look for wording such as:
1This standby is subject to the International Standby Practices 1998,
2International Chamber of Commerce Publication No. 590 (ISP98).
The example is illustrative, not drafting advice. The actual text may modify or exclude particular rules. A separate reimbursement agreement or underlying contract referring to ISP98 does not necessarily prove that the issued standby itself incorporates ISP98.
ISP98 describes a standby as having four linked characteristics:
| Characteristic | Practical meaning |
|---|---|
| Irrevocable | The issuer cannot simply withdraw its undertaking after issuance; cancellation or amendment must follow the standby and applicable rules |
| Independent | The issuer’s obligation does not depend on its reimbursement rights or on deciding the merits of the underlying transaction |
| Documentary | Honor depends on presentation and examination of the documents required by the standby |
| Binding when issued | The undertaking becomes binding when it leaves the issuer’s control unless it clearly states a different issuance condition |
Independence does not mean fraud, abuse, authority, injunctions, or mandatory law are irrelevant. ISP98 expressly leaves several of those issues outside its scope. Parties need jurisdiction-specific legal analysis where they matter.
| Rule group | Main subject |
|---|---|
| Rule 1 | Scope, relationship to law, interpretation, effect, nature, and terminology |
| Rule 2 | Issuer and confirmer obligations, issuance, nomination, advising, and amendments |
| Rule 3 | Time, place, person, medium, identification, partial drawing, multiple presentation, and extend-or-pay requests |
| Rule 4 | Examination of documents and common documentary questions |
| Rule 5 | Notice of dishonor, grounds, preclusion, waivers, and disposition of documents |
| Rule 6 | Transfer of drawing rights, assignment of proceeds, and transfer by operation of law |
| Rule 7 | Cancellation and termination |
| Rule 8 | Reimbursement obligations |
| Rule 9 | Timing rules |
| Rule 10 | Syndication and participation |
This map is an orientation tool. A transaction should be reviewed against the complete rule text, the issued standby, and applicable law.
A standby should identify when, where, to whom, and in what medium presentation must be made. A beneficiary should not assume that sending documents to the applicant, an advising bank, or a general bank email address constitutes presentation to the issuer.
The presentation may require only a demand and beneficiary statement, or it may require certificates, copies of notices, invoices, drafts, or third-party documents. Every added requirement creates another possible discrepancy. The issuer examines the documents in the context of standby practice, even if similar documents would be treated differently under commercial-credit rules.
ISP98 Rule 5.01 requires notice of dishonor within a time after presentation that is not unreasonable. Under the rule:
The standby can expressly state a shorter period. The notice should identify all discrepancies on which dishonor is based. Missing the rule’s notice requirements can preclude reliance on a discrepancy or create a payment obligation, so timing and content are operational controls, not minor administration.
A lender requires a $850,000 financial standby to support a borrower’s scheduled payment obligation. The standby is subject to ISP98 and requires presentation before expiry of:
The borrower misses a payment. The lender presents both documents for $300,000 at the issuer’s stated office before expiry. The issuer examines whether the documents appear on their face to comply. The issuer does not need a court judgment merely because the borrower disputes an offset, unless the standby itself requires one or applicable law intervenes.
Now assume the lender sends only a demand and omits the required signed default statement. The presentation is discrepant even if the payment failure is real. If the issuer dishonors, its notice should be timely and state the omitted-document discrepancy. The beneficiary may be able to correct and re-present only if the standby has not expired and its terms permit another presentation.
This distinction is central: ISP98 organizes documentary standby practice; it does not replace careful drafting or guarantee that a commercially justified claim will comply.
An applicant cannot assume that asking the issuer to cancel or amend a standby changes the beneficiary’s rights. The amendment process depends on the instrument and ISP98. A beneficiary may reject an amendment, and partial consent to an amendment is not the same as accepting only favorable terms.
Automatically extendable standbys, often called evergreen standbys, require precise non-extension notice procedures. Review:
Do not rely on the word “evergreen” alone. ISP98 notes that some commonly used terms lack a single accepted meaning unless context supplies one.
Transfer changes who may exercise drawing rights and is available only when the standby states that it is transferable and the required party agrees to effect the transfer under the applicable conditions. Assignment of proceeds concerns where money from a drawing may be paid; it does not by itself give the assignee the beneficiary’s right to draw.
Confusing these concepts can leave a purchaser or lender with an assignment of possible proceeds but no ability to make the presentation that creates those proceeds.
| Rules | Designed primarily for | Key boundary |
|---|---|---|
| ISP98 | Standby letters of credit and similar independent undertakings | Standby-specific presentation, examination, transfer, cancellation, and timing rules |
| UCP 600 | Documentary commercial credits | Can apply to standbys when incorporated, but some commercial-credit provisions may not fit standby practice |
| URDG 758 | Demand guarantees and counter-guarantees | Applies only when the demand guarantee expressly indicates it is subject to URDG |
| URC 522 | Documentary collections | Banks handle documents as agents without the issuing-bank undertaking found in a credit |
The rules are not interchangeable labels. The instrument should name the intended rule set, and its operative terms should be drafted to work with that choice.
ISP98 does not, by itself, settle:
Those questions depend on applicable law, separate agreements, regulatory requirements, and facts.
