SCT vs SCT Inst
The SEPA Credit Transfer and SEPA Instant Credit Transfer schemes move euro between the same kinds of participants using the same ISO 20022 messages, but on fundamentally different clocks and operating models.
| DIMENSION | SCT | SCT Inst |
|---|---|---|
| Processing model | Batch-oriented: instructions are collected, exchanged, and settled through clearing cycles on banking days. | Single-transaction and real-time: each payment is processed individually, end to end, the moment it is submitted. |
| Speed and deadlinesWe deliberately keep the numbers out of this table — check the current SCT Inst rulebook for the exact execution-time target and timeout values in force. | Execution timelines are defined in banking days; a transfer submitted after cut-off waits for the next cycle. | The rulebook sets a target execution time measured in seconds and a hard timeout: if the confirmation does not arrive in time, the transfer fails rather than waits. |
| Availability | Tied to banking days and each participant's cut-off times. | Around the clock, every day of the year — which means the receiving bank's validation, screening, and posting must also run continuously. |
| Settlement and liquidity | Typically cleared in batches through a clearing and settlement mechanism, with net positions settled at designated times; liquidity is managed around known cycles. | Settled continuously, commonly against pre-funded positions (for example in TIPS or RT1), so treasury must keep the instant-payments position funded at night and on weekends. |
| When the beneficiary gets the money | On the value date, after the relevant clearing and settlement cycle completes. | Within seconds of a successful confirmation — the funds must be made available to the beneficiary immediately. |
| Exception handlingThe academy's timeout and recall-refused exception scenarios show both failure modes step by step. | Rejects can occur at several points before settlement; returns and recalls happen afterwards on banking-day timelines. | Most failures are immediate rejects inside the timeout window (including the timeout itself); because funds are credited instantly, getting money back afterwards relies on the recall process, and the beneficiary's PSP can refuse. |
| Screening and fraud controlsEuropean verification-of-payee requirements add a pre-payment name check on both schemes; see the Verification of Payee topic. | Controls can run in batch windows with time for manual review before value moves. | Controls must decide in real time; anything that needs human review effectively fails the payment, which pushes institutions towards better data and tuned automation. |
| Amount limits | The scheme itself does not cap the amount; practical limits come from clearing systems and individual PSPs. | Scheme rules on maximum amounts have changed over time, and PSPs and CSMs apply their own limits — verify the current rulebook and your providers' limits rather than assuming a figure. |

What this simplifies: Settlement arrangements are simplified: SCT clearing and settlement models vary by CSM, and instant settlement mechanics differ between TIPS, RT1, and other arrangements. Exact execution times, timeouts, and amount rules belong to the current rulebooks, not this table.
