No answer in time: an instant payment that timed out

Trigger: No confirmation arrives within the scheme's time limit after Bank Alfa sends the instant payment.

Contributor Shubham Mathure

What operations sees first: The customer is still looking at a spinner; the operations dashboard shows an outbound pacs.008 with no final status inside the expected few seconds.

WHERE IS THE MONEY?

Reserved on the debtor's account during the attempt, then released; no money left the bank.

DID SETTLEMENT HAPPEN?

Never became final — any funds positioned for the attempt were released when the timeout was declared.

WHO ACTS NEXT?

Nordbank or the instant CSM — whichever let the clock run out (AB05 versus AB06 says which) The customer retries. If timeouts cluster on one counterparty or one time window, operations raises it with the CSM or the beneficiary bank.

PLAY THE EXCEPTION

Trigger: The beneficiary side does not answer inside the scheme's time limit, so the payment cannot complete.

STEP 1 / 7MESSAGE

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. 05 · EXCEPTION PATHProcessing
    The CSM treats the payment as failedInstant CSM (e.g. TIPS-style)

    Instant schemes are all-or-nothing: with no positive answer in time, the transfer must not settle. An unanswered payment is resolved as a failure, never left hanging.

  6. 06 · EXCEPTION PATHMessage
    Bank Alfa receives a negative statusInstant CSM (e.g. TIPS-style) → Bank Alfa (debtor agent) · pacs.002

    The rejection carries a timeout reason so operations can distinguish a slow participant from a business refusal.

  7. 07 · EXCEPTION PATHPosting
    The reservation is releasedBank Alfa (debtor agent)

    The debtor's money never left — the earmark is simply removed and the customer is told the payment failed.

    • RELEASE Debtor's current account at Bank Alfa — EUR 480.00
  8. OUTCOME
    Funds
    Never left the debtor's account — the reservation was released.
    Settlement

THE TIMELINE

  1. 01Debtor
    Initiates an instant transfer; Bank Alfa validates the instruction and places a reservation on the account.
  2. 02Bank Alfa
    Sends the transfer into the instant CSM, which starts the scheme's execution clock.pacs.008
  3. 03Instant CSM
    No positive confirmation is received within the time limit — the transaction must fail rather than hang.

    In an instant scheme, 'no answer' is itself an outcome: the rulebook defines a hard time limit so payments end with certainty.

  4. 04Instant CSM
    A negative status report travels back to Bank Alfa reporting the timeout — reason code AB05 when the creditor agent timed out, AB06 when the CSM or another instructed agent did.pacs.002
  5. 05Bank Alfa
    Releases the reservation on the debtor's account and shows the customer a clear failure so they can retry.

Resolution: The payment fails definitively rather than hanging in an ambiguous state. The reservation is released, and a retry a moment later often succeeds if the beneficiary side had a transient problem.
