The Full Form of ISBP is International Standard Banking Practice.

The ISBP (full title: International Standard Banking Practice for the Examination of Documents under Documentary Credits) is an International Chamber of Commerce (ICC) publication which provides important guidance to documentary credit examiners and practitioners relating to the examination of documents presented against Letters of Credit. It is important to note that the ISBP cannot in any way change the UCP 600 rules which apply to Letters of Credit, but the ISBP is a valuable supplementary guide to UCP.

The first ISBP was formally approved in 2002 and this first version acted as a companion guide to Uniform Customs and Practice  (UCP) 500 which were the current rules that governed Letters of Credit at that time. However, when the rules were revised to UCP 600 in July 2007, the ISBP was duly updated by the ICC publication No.681, thus aligning the ISBP with the newly updated UCP.
