On 28 March 2023, the European Payments Council (EPC) published the first version of the One-Leg Out Instant Credit Transfer (OCT Inst) rulebook following a public consultation on a proposed [Instant] Euro One-Leg Out Credit Transfer ([Inst] Euro OCT) Arrangement Rulebook (EPC145-21) organised from mid-January 2022 to mid-April 2022.
The outcome of this 2022 public consultation led to considerable changes to the initial [Inst] Euro OCT Arrangement Rulebook which resulted into the version 1.0 of the 2023 OCT Inst rulebook covering now exclusively the Euro Leg of international instant credit transfer-based payment transactions.
The 2023 OCT Inst rulebook version 1.0 takes effect on 28 November 2023 at 08:00 CET and remains in effect until November 2025.
