What are bank statements, and what info do they contain
Let’s start by going through the type of reports banks usually make available to their customers and what information they include.
Account reports – or CAMT messages
CAMT messages are a
set of standard messages defined in the ISO 20022 standard that is used across many payment schemes worldwide to codify how information should be exchanged between financial institutions and their customers.
Depending on the schemes, CAMT messages are used as defined in the ISO 20022 standard or with slight variations (e.g. SEPA) or replaced by equivalent messages (e.g.
Bacs)
For the sake of simplicity, we’ll focus on the messages as defined in the ISO 20022 standard.
ISO 20022 specifies three distinct types of account reports and the corresponding CAMT messages.
Depending on their capabilities, banks might generate camt.052 intraday account reports every few hours and camt.054, debit / credit notification account reports every few minutes, and camt.053 prior-day account reports shortly before or after midnight.
Although they contain the same transactions, debit / credit notification, intra-day, and prior-day account reports can be difficult to reconcile, as they do not always use a common ID for a given transaction.
Banks make both camt.052 and camt.053 available to customers because camt.052 contains information that might not be final. Indeed, a debit transaction for instance might correspond to a payment made from the bank account to an outside beneficiary, that has been accepted by the bank but not sent to the CSM yet.
This payment can be blocked at the CSM level for technical reasons, or rejected by the beneficiary bank for various reasons. Therefore, the corresponding transaction might appear in the intra-day report, and the intra-day balance might reflect this transaction, but if something goes wrong, the intra-day report might not represent the reality of the bank account at the end of the day.
camt.052 and camt.053 account reports contain account balances. The ISO 20022 standard specifies the different types of balances which can be included in account reports.
