ISP98: Rules, Presentation, and Bank Review

ISP98, formally the International Standby Practices and published by the International Chamber of Commerce as Publication No. 590, is the specialized rulebook for standby letters of credit. It took effect on January 1, 1999, and remains the dominant framework for standby practice worldwide.¹ Unlike UCP 600, which governs commercial letters of credit tied to shipments and trade, ISP98 addresses instruments that function more like guarantees: the beneficiary draws only when the other party fails to perform.

How ISP98 Gets Into a Standby

The rules do not apply automatically. A standby falls under ISP98 only when the instrument itself incorporates them, usually through a clause stating the standby is “subject to ISP98” or “ICC Publication 590.” That incorporation creates a binding obligation between issuer and beneficiary under the ISP98 framework.¹ Without that reference, the standby falls back on whatever local law or other rules the parties have chosen.

A core principle runs through the whole rulebook: the standby is independent from the underlying business deal. The issuing bank does not evaluate whether the applicant actually failed to perform a contract, delivered defective goods, or missed a deadline. The bank’s only job is to check whether the documents presented by the beneficiary comply with what the standby requires.¹ That independence is what makes the instrument valuable as security. Payment turns on paperwork, not on resolving the dispute first.

A standby is also irrevocable once issued. The issuing bank cannot unilaterally amend or cancel it. Any change requires either a provision in the standby allowing modification or the consent of the affected party. The ISP98 rules fill operational gaps where the standby’s own text is silent, covering timing, document handling, and notice.

What ISP98 Changes Versus UCP 600

Parties sometimes default to UCP 600, the rules built for commercial documentary credits, when issuing a standby. That is possible, but ISP98 was written specifically for standbys and handles several operational issues differently.²

Document examination time. UCP 600 gives the bank up to five business days. ISP98 uses a sliding scale: three business days is a safe harbor where the bank is presumed timely, anything past seven is deemed unreasonable, and the middle range depends on circumstances.
Demand for payment. UCP 600 does not require a separate demand. Under ISP98, the beneficiary normally must submit an explicit written demand.
Originals and copies. UCP 600 requires originals unless the credit says otherwise. ISP98 generally treats copies as acceptable except for the demand itself.
Transfer. UCP 600 permits partial transfer. ISP98 allows only full transfer.
Document language. ISP98 requires documents to be in the language of the standby. UCP 600 does not impose a comparable blanket requirement.
Renewal. Commercial documentary credits are not meant to renew. ISP98 expressly accommodates automatic extension clauses.
Syndication. ISP98 contains specific provisions for syndicated standbys. UCP 600 does not address syndication directly.

When the underlying transaction is a performance guarantee, a financial backup facility, or any other arrangement where a draw signals default rather than routine trade performance, ISP98 is the better fit.

How Domestic Law Fits In

In the United States, standby letters of credit are also governed by Article 5 of the Uniform Commercial Code, adopted in some form in every state. When a standby incorporates ISP98, those rules supplement and modify Article 5’s defaults. UCC Section 5-103(c) explicitly permits parties to vary Article 5 “by agreement or by a provision stated or incorporated by reference in an undertaking.”³

That flexibility has limits. Certain UCC provisions cannot be overridden by contract or practice rules, including the definitions of key terms and the statute of limitations for letter of credit claims. UCC Section 5-116(c) sets the hierarchy: where ISP98 and Article 5 conflict, ISP98 governs except where the conflict involves one of those nonvariable provisions.⁴

The Fraud Exception

ISP98 deliberately does not address fraud. That gap matters, because the independence principle would otherwise require a bank to honor any facially compliant presentation no matter what the applicant alleges about the beneficiary. In the United States, UCC Section 5-109 fills the gap. It permits an issuing bank acting in good faith to dishonor a presentation when a required document is forged or materially fraudulent, or when paying would facilitate a material fraud by the beneficiary.⁵

An applicant who suspects fraud can also ask a court to enjoin the bank from paying. The bar is high. The applicant must show it is more likely than not to prove forgery or material fraud, the court must ensure adequate protection for anyone harmed by the injunction, and the person demanding payment must not be a protected party such as a confirming bank that acted in good faith without notice of the fraud.⁵ Courts grant these injunctions sparingly in practice. The independence principle is the default, fraud the narrow exception.

Choice of Law

If a standby names a governing jurisdiction, that jurisdiction’s law applies to the issuer’s liability. If it does not, UCC Section 5-116(b) defaults to the law of the jurisdiction where the issuer is located, determined by the address indicated in the undertaking.⁴ For international standbys where the issuer sits outside the United States, the answer depends on the issuer’s home jurisdiction, which may or may not follow UCC rules. The choice-of-law clause deserves more attention at drafting than most parties give it.

Making a Compliant Presentation

Getting paid under a standby means submitting documents that match the credit’s requirements exactly. A valid demand must be in writing, bear a signature, and identify the standby by its reference number. Most standbys also require a statement certifying that the applicant has failed to perform a specific obligation. The wording of that statement matters enormously. If the standby requires a certificate saying the applicant “failed to deliver goods by the contractual delivery date,” a certificate saying the applicant “breached the delivery obligation” may be rejected as non-compliant. When the standby demands exact or identical language, reproduce it verbatim.

ISP98 is pragmatic about originals and copies. A document is treated as an original if it appears to have been signed or issued by the required party, unless the standby specifically calls for a copy. That is more flexible than UCP 600’s default. If the standby requires electronic presentation, it should say so explicitly. Documents must be in the language of the standby unless otherwise indicated.²

The package must be complete and delivered to the specified location before the closing time on the expiration date. Missing a required document, omitting a signature, or failing to include any stamps or notarizations will produce a non-compliant presentation. The real cost of a discrepancy is not the fee the bank charges but the time lost. If the expiration date passes while you are correcting the problem, you lose the right to draw entirely.

How the Bank Reviews and Responds

Once the beneficiary presents, the issuing bank reviews for compliance. ISP98 gives the bank a three-business-day safe harbor during which it is presumed to have acted timely, whether it honors or dishonors. Taking longer than seven business days is automatically deemed unreasonable. Between three and seven, reasonableness turns on the complexity of the documents and the circumstances. The bank’s clock does not shift based on whether the beneficiary has an approaching deadline to re-present.²

Notice of Dishonor

If the bank identifies discrepancies, it must send a notice of dishonor promptly, listing every discrepancy it relies on. The bank cannot hold back a reason and raise it later. This single-shot rule is one of ISP98’s most important protections for beneficiaries, because it stops an issuer from stringing out the process by citing one problem, then discovering another after the beneficiary fixes the first. The standby can specify who should receive the notice and how. If it does not, the notice goes to the presenter by the fastest available method.

Correcting and Re-Presenting

A beneficiary who receives a notice of dishonor can fix the identified problems and re-present, provided the standby has not yet expired. The bank then examines the corrected presentation fresh, on the same timeline. Watch for one trap. If the beneficiary asks the bank to forward the documents to the applicant or to seek the applicant’s waiver of the discrepancies, the beneficiary gives up the right to later object to those discrepancies. The waiver request effectively concedes the bank’s findings were valid.

Transfer Versus Assignment of Proceeds

ISP98 draws a sharp line between two ways a third party can acquire rights under a standby, and confusing them is a common and expensive mistake.

A transfer of drawing rights gives a new beneficiary the full ability to present documents and demand payment as though it were the original beneficiary. Under ISP98, the standby must expressly state that it is transferable for this to be possible, and only a full transfer is allowed. No partial transfers. The transfer requires the issuer’s consent and completion of the bank’s transfer forms, along with a processing fee.²

An assignment of proceeds is a narrower right. The original beneficiary keeps the power to draw, but a third party receives the money if a compliant draw is made. The issuing bank is not obligated to honor an assignment it has not acknowledged, so anyone relying on an assignment of proceeds should confirm the bank has received and accepted formal notice. In financing arrangements, lenders often take an assignment of proceeds as security. They depend entirely on the original beneficiary actually making a compliant presentation.

Automatic Extension Clauses

Many standbys include automatic extension provisions, commonly called evergreen clauses, that renew the credit for successive periods unless the issuer sends a non-renewal notice within a stated window. ISP98 expressly accommodates this, unlike UCP 600 which does not contemplate renewable credits.²

Drafting matters. The term “evergreen” itself has no single accepted meaning in banking practice and is best avoided in the standby text. The clause should use “extended” rather than “renewed” or “replenished,” since the latter terms can be confused with revolving credit mechanics. Including the word “automatic” clarifies that the beneficiary’s consent is not needed for the extension to take effect. If the standby separates the expiration clause from the extension clause without cross-referencing them, the provision risks being treated as ambiguous and interpreted against the issuer.

Bank Closures and the 30-Day Extension

ISP98 provides a meaningful safety net when a bank closure prevents timely presentation. Under Rule 3.14, if the place for presentation is closed on the last business day for presentation for any reason, the expiration date automatically extends to 30 calendar days after the location reopens for business.⁶

This departs from UCP 600, which places the risk of issuer closure due to force majeure on the beneficiary. Under ISP98 the beneficiary gets a real cushion. Parties can modify or exclude the 30-day extension by stating different terms in the standby itself. Applicants who want tighter control over the duration of their contingent exposure sometimes do this. If you are the beneficiary, check whether the standby has overridden the default force majeure protection before assuming you have it.

Expiration and Cancellation

A standby expires automatically at the end of the business day on the date stated in the document. No action by any party is needed; the clock simply runs out. If the stated date falls on a day when the presentation location is not open for business, the deadline extends to the next business day. This non-business-day extension under Rule 3.13 is separate from the 30-day force majeure extension under Rule 3.14, and the two cover different situations.

Cancellation before the stated expiration requires the beneficiary’s consent. Because the standby is irrevocable, the issuer cannot walk away from its obligation while the credit remains live. The beneficiary typically must return the original standby document or provide a written release before the bank will treat the obligation as cancelled.

Once expiration occurs, the bank’s liability ends completely, even if the beneficiary still holds the physical document. For the applicant, this usually means the bank releases any collateral or reduces any credit facility tied to the standby shortly afterward. For the beneficiary, the message is blunt. A compliant presentation that arrives even one day late is worth nothing.

Fees to Budget For

Standby letters of credit carry several layers of fees beyond the face amount. Issuance fees are typically quoted as an annual percentage of the standby amount, commonly ranging from about 1% to 3% depending on the applicant’s creditworthiness, the size and duration of the standby, and whether the bank holds collateral. Some banks also charge a flat upfront application or administrative fee at issuance.

Discrepancy fees run in the range of $75 to $150 per presentation when the bank identifies errors. Transfer fees apply if the standby is transferred to a new beneficiary and vary by institution. Amendment fees are charged whenever the terms change, for example extending the expiration date or increasing the amount. These transactional costs add up in long-running standby arrangements with automatic extension clauses, where amendment and review cycles repeat annually. Getting the standby’s terms right at issuance and ensuring the first presentation is compliant is far cheaper than fixing problems afterward.
