On 30 June 2023, the European Payments Council (EPC) published version 1.1 of the 2023 One-Leg Out Instant Credit Transfer (OCT Inst) rulebook replacing with immediate effect version 1.0 of that same rulebook, along with the publication of the related OCT Inst scheme Customer-to-Payment Service Provider (PSP) (C2PSP) Implementation Guidelines (IGs) and the OCT Inst scheme Inter-PSP IGs.
Version 1.1 has no specific impact on the business and operational rules compared to version 1.0 of the 2023 OCT Inst rulebook. It includes just a limited set of changes and/or clarifications resulting from the creation of the related OCT Inst scheme Customer-to-PSP and Inter-PSP IGs.
Annex IV of the 2023 OCT Inst rulebook version 1.1 lists all changes compared to version 1.0 of the 2023 OCT Inst rulebook.
The 2023 OCT Inst rulebook version 1.1 takes effect on 28 November 2023 at 08:00 CET and remains in effect until November 2025.
