STEP 1 / 9MESSAGE

The debtor initiates an instant payment

Debtor (payer) → Bank Alfa (debtor agent)

The customer pays from an app or channel. From this moment the scheme's clock is running — the whole journey must finish within the scheme's time limit.

    Bank Alfa validates in real timeBank Alfa (debtor agent)

    Format checks, balance check, and sanctions screening all happen in seconds. Anything slow here burns the scheme's time budget.

    Screening checkpoint: Real-time transaction screening — Instant rails force screening to be fast and highly automated — there is no batch window to hide latency in.

  3. 03Posting
    The debtor's funds are reservedBank Alfa (debtor agent)

    Bank Alfa earmarks the amount. The final debit is confirmed only when the beneficiary bank accepts — instant payments are all-or-nothing.

    • RESERVE Debtor's current account at Bank Alfa — EUR 480.00
  4. 04Message
    The transfer goes to the instant CSMBank Alfa (debtor agent) → Instant CSM (e.g. TIPS-style) · pacs.008

    A pacs.008 flagged for the instant scheme is sent to the CSM, which immediately pushes it onward.

  5. 05Message
    Nordbank receives the transfer immediatelyInstant CSM (e.g. TIPS-style) → Nordbank (creditor agent) · pacs.008

    The CSM forwards the payment in real time and waits for the beneficiary bank's answer.

  6. 06Processing
    Nordbank decides — nowNordbank (creditor agent)

    The creditor agent validates the account and screens the payment, then must answer positively or negatively within the scheme's window.

  7. 07Message
    A positive status confirms acceptanceNordbank (creditor agent) → Instant CSM (e.g. TIPS-style) · pacs.002

    The pacs.002 positive status is the trigger for settlement and for both customers' account movements.

  8. 08Settlement
    Settlement happens immediately from prefunded positionsBank Alfa (debtor agent) → Nordbank (creditor agent)

    The CSM moves the amount between the banks' prefunded positions in central bank money the moment the positive answer arrives. There is no waiting for a cycle.

    • DR Bank Alfa prefunded position — EUR 480.00
    • CR Nordbank prefunded position — EUR 480.00
  9. 09Posting
    The creditor is credited within secondsNordbank (creditor agent)

    The beneficiary can use the money immediately. Bank Alfa converts the reservation into a final debit at the same moment.

    • CR Creditor's current account at Nordbank — EUR 480.00

What this simplifies: One instant CSM with prefunded settlement. Exact time limits, investigation procedures, and multi-CSM reachability are defined by the scheme rulebook and omitted here.
