Swift consider Bunq not compatible and ready for ISO20022 and thus CAMT053 is not available. I'm a big fan of Bunq and I love to see this for automatic accounting.
CAMT053 and CAMT052 would offer comprehensive and detail information that we can integrate automatic accounting without worry of duplicate transaction, or mismatching of openning and closing balance.
Unfortunately MT940 does not include these detail information. and if so MT942 is also needed at a given time to split floating transactions and avoid duplicate record in account.
