ISO 20022 bank transaction code

CAMT/ACCB/SWEP: Sweeping

An automatic sweep: the balance above an agreed floor moves to another account, often a concentration account that pools cash from several accounts.

What CAMT/ACCB/SWEP means

A bank transaction code classifies an entry in three levels, each narrower than the last. Read together, CAMT/ACCB/SWEP reads Cash Management › Account Balancing › Sweeping.

  • CAMT (Cash Management). Moves between your own accounts to concentrate or balance cash, such as sweeping, zero balancing and topping.
  • ACCB (Account Balancing). Automated moves that set an account’s balance to an agreed level.
  • SWEP (Sweeping).

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

The same sweep is a debit on the account swept and a credit on the account it went to. Sweeps are booked by the bank under the cash management agreement, so there is no payment file of yours to match: reconcile the two sides against each other.

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 NCMS (Cash management item — sweeping). 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.
