What PMNT/ICDT/BOOK means

A bank transaction code classifies an entry in three levels, each narrower than the last. Read together, PMNT/ICDT/BOOK reads Payments › Issued Credit Transfers › Internal Book Transfer.

  • PMNT (Payments). Every movement of funds between parties, such as transfers, direct debits, cheques, cards and cash.
  • ICDT (Issued Credit Transfers). Payments the account owner sent.
  • BOOK (Internal Book Transfer).

Where it sits in a camt.053

The code is in each entry’s BkTxCd/Domn block, the same way in camt.052, camt.053 and camt.054 and in every version from .001.02 to .001.13:

camt.053.001.08 · an entry

  …
</Ntry>

Banks may add their own code in BkTxCd/Prtry, next to the ISO code or instead of it (a German bank’s three-digit business transaction code, for example). Prefer the ISO code for rules that should work across banks.

What the entry carries

Typical for moves between your own accounts at one bank. The receiving account is in RltdPties/CdtrAcct; the same transfer appears as PMNT/RCDT/BOOK on the receiving account’s statement.

In an MT940

An MT940 has no ISO code: each :61: statement line carries a three-letter transaction type after an identification letter. The one with the same meaning is NTRF (Transfer). It is coarser than the ISO code, so several ISO codes share it.

The MT940 Viewer converts MT940 to camt.053, and keeps the :61: type as a proprietary code (BkTxCd/Prtry, issuer SWIFT) rather than guessing an ISO code. All the types are in the MT940 transaction type codes.
