Summary
Purpose and Scope
The 2025 SCT Inst rulebook coordinates continuously available instant euro transfers between participating providers. ISO 20022 guidance, participant duties and outcome handling support rapid execution, with the scheme read alongside the EU's ten-second legal execution requirements.
Instant Transfer Model
EPC describes funds becoming available in less than ten seconds at any time through participating providers. The rulebook coordinates responsibilities and handling of the transfer outcome.
Message Layer
Customer-to-PSP and inter-PSP implementation guidelines for 2025 use the 2019 ISO 20022 message version. The scheme is separate from the clearing infrastructure chosen by participants and should be read alongside applicable legal execution requirements.
Edition Status
Version 1.2 replaced v1.1 on 30 September 2026 and deferred the unstructured-address deadline without changing other business or operating rules. EPC has not set a replacement end date. The former 15 November 2026 deadline belongs to the superseded v1.1 edition.
