On 21 November 2017, the European Payments Council (EPC) launched the SEPA Instant Credit Transfer (SCT Inst) scheme. For the first time, euro-denominated instant payments could flow between participating banks across SEPA member countries, 24 hours a day, 365 days a year, with funds credited to the beneficiary within 10 seconds.
Scheme Design
SCT Inst was designed as an overlay on the existing SEPA Credit Transfer scheme, adding a real-time processing requirement. Key parameters at launch:
Maximum execution time: 10 seconds from initiation to credit confirmation
Initial transaction limit: EUR 15,000 (later raised to EUR 100,000) Availability: 24/7/365, including weekends and holidays Geographic reach: all SEPA countries (36 countries, over 4,000 PSPs potentially reachable) ISO 20022 messaging format
Voluntary Participation
Critically, participation in SCT Inst was voluntary at launch. While the standard SEPA Credit Transfer was mandatory for all euro-area banks, instant was optional. This meant that coverage was initially patchy - some countries and banks were early adopters, while others took years to join.
At launch, approximately 585 payment service providers across 8 SEPA countries were reachable via SCT Inst. Coverage varied dramatically: some countries had near-universal participation while others had none.
Settlement Infrastructure
Transactions between banks could settle through multiple Clearing and Settlement Mechanisms (CSMs). EBA Clearing's RT1 was the first pan-European clearing infrastructure for SCT Inst. The ECB's TIPS (TARGET Instant Payment Settlement) launched a year later in November 2018, offering settlement in central bank money.
Path to Mandatory Adoption
The voluntary nature of SCT Inst meant that adoption was slower than many had hoped. By 2024, while coverage had expanded significantly, gaps remained. This eventually led to the EU Instant Payments Regulation (2024), which mandated that all SEPA banks offer instant payments - effectively making SCT Inst as universal as the standard credit transfer.
