Standby Rules
ISP98 is the ruleset used for standby letters of credit. It was drafted specifically for standby practice and sets out how these instruments are issued, presented, examined, and honored. When a standby states that it is subject to ISP98, the parties are working inside a recognized framework instead of arguing from scratch each time a drafting, presentation, or draw issue appears.
What ISP98 Is
ISP98 stands for International Standby Practices 1998. It is not a generic banking rulebook. It is a rules framework written specifically for standby letters of credit, which are commonly used as backup payment or performance undertakings in commercial transactions.
That matters because a standby does not behave like a standard documentary letter of credit used to pay against shipping documents. A standby is usually there to support an obligation if the applicant fails to perform or pay. It may support repayment, lease obligations, contract performance, tender participation, or other commercial exposures. If you are comparing standby structures with other letter-of-credit formats, see SBLC vs DLC: Which Letter of Credit Is Right for Your Deal?.
Practical point:
ISP98 gives issuers, applicants, and beneficiaries a shared operating framework for standby practice.
Why ISP98 Matters
Without a rules framework, standby disputes get ugly fast. People start arguing about whether a demand was properly made, whether documents were compliant, whether a notice of dishonor was timely, or what happens if an expiry date lands badly. ISP98 cuts down that noise by setting a default rule set for routine standby issues.
It does not fix weak drafting, and it does not rescue a badly structured transaction. Still, it helps reduce avoidable confusion and gives the parties a known baseline. For broader standby and transaction structuring work, see What We Do.
It Was Written For Standbys
ISP98 reflects the way standby letters of credit are actually used in commercial practice, rather than borrowing rules built for something else.
It Improves Predictability
It gives the parties a clearer framework for presentations, examination, dishonor notices, expiry, transfer, and other routine issues.
It Reduces Friction
Many operational questions are answered by the rules instead of being left entirely to argument after the fact.
It Still Needs Good Drafting
The rules help, but the standby wording still has to match the commercial obligation and the draw conditions still have to make sense.
What ISP98 Generally Covers
ISP98 deals with the mechanics of standby practice. It addresses how a standby is interpreted, how a demand or other document may be presented, how the issuer examines the presentation, when dishonor must be notified, and how questions around expiry, transfer, assignment, and extension are treated.
| Topic |
Why It Matters |
| Presentation |
Helps determine how demands and documents are submitted and what counts as a proper presentation. |
| Examination |
Sets the framework for how the issuer reviews documents and decides whether they comply on their face. |
| Notice of Dishonor |
Addresses how and when the issuer must notify the presenter if a demand is rejected. |
| Expiry |
Clarifies timing issues, expiry dates, and the place for presentation. |
| Transfer and Assignment |
Helps frame what rights may be transferred or assigned, depending on the instrument text. |
| Automatic Extension |
Relevant for evergreen standbys and extension language frequently used in commercial transactions. |
ISP98 Versus UCP 600
These two get mixed up constantly. UCP 600 is mainly associated with documentary credits used in trade transactions. ISP98 was drafted specifically for standbys. A standby can be issued subject to UCP 600, but many practitioners prefer ISP98 because it is a better fit for backup payment and performance undertakings.
That distinction matters in practice. A documentary credit is usually designed to pay against stipulated documents in a trade flow. A standby is usually there to backstop an obligation if something goes wrong.

Common mistake:
thinking the rules are the whole transaction. They are not. The standby text, the underlying contract, and the commercial logic still have to line up properly.
Where ISP98 Shows Up In Practice
- Payment standbys
- Performance standbys
- Lease support standbys
- Repayment support standbys
- Bid and tender standby structures
- Commercial contracts that need bank-backed backup support
Why This Matters To Clients
If you are reviewing a standby, the governing rules matter because they affect how the instrument behaves when something goes right and when something goes wrong. A beneficiary cares whether its draw rights are workable. An applicant cares whether the wording is fair and tied to the real obligation. An issuer cares about operational clarity and document review risk.
That is why a short ISP98 overview is useful, but never enough on its own. The real work is in matching the standby wording, the rules, and the underlying transaction. If you need help with a live file, you can start through Request A Quote.

If your transaction involves a standby governed by ISP98, the wording and commercial fit matter more than buzzwords. Submit the requirement if you need a serious transaction-led review.
Frequently Asked Questions
What does ISP98 stand for?
It stands for International Standby Practices 1998, the ruleset drafted specifically for standby letters of credit.
Is ISP98 the same as UCP 600?
No. UCP 600 is mainly associated with documentary credits, while ISP98 was drafted specifically for standby practice.
Does ISP98 apply automatically?
No. The standby normally needs to state that it is subject to ISP98. The rules apply because the instrument incorporates them.
Why do practitioners prefer ISP98 for standbys?
Because it was written for standby behavior and usually provides a cleaner fit for backup payment and performance obligations than documentary-credit rules.
Do the rules eliminate the need for careful drafting?
No. The rules help, but the standby wording still has to be drafted properly and tied to the underlying commercial transaction.
