The camt family: cash management & investigations

IN ONE LINE

Analogy: if pacs messages are the freight moving between depots, camt messages are the depot's office paperwork.

Some of it is routine reporting — the end-of-day list of everything that arrived and everything that left, so the books can be checked.

And some of it is correspondence about problems: a camt.056 is the letter that says "we sent you parcel 4711 by mistake — please send it back", and a camt.029 is the reply, which might be "certainly, it is on its way" or "we cannot; the recipient has already opened it." Asking is easy and standardised.

Actually getting the parcel back depends entirely on what the other depot answers.

WHAT IT ACTUALLY IS

camt stands for cash management, and the family covers two quite different jobs.

Account reporting messages carry balance and entry information from an account servicer to the account owner — the ISO 20022 successors to statement formats like the MT940.

Exceptions and investigations messages manage what happens after a payment goes wrong: camt.056, the FI-to-FI payment cancellation request, asks a downstream agent to stop an in-flight payment or give back a settled one; camt.029, the resolution of investigation, carries the answer — cancelled, funds being returned, or a refusal with a reason.

Both sides reference the original transaction identifiers, so every party can tie the case to the exact payment it concerns.

HOW IT WORKS

The point practitioners must internalise: a camt.056 is a request, never an instruction.

Once a payment has settled, the money sits with the beneficiary's bank or the beneficiary, and no message format can demand it back.

The receiving side investigates — often needing the beneficiary's consent — and answers with a camt.029.

If funds do come back, they travel in a pacs.004 return, not in the camt itself.

Correlation discipline matters: case references, original identifiers, and the UETR must line up, or investigation teams end up matching by amount and date.

Obligations and timelines vary by rail — a SEPA recall follows the EPC rulebook's defined process, while cross-border cases follow correspondent practice — so the same message carries different expectations on different rails.
