MT940 → CAMT.053

Convert MT940 to CAMT.053

Convert legacy SWIFT MT940 statements to ISO 20022 CAMT.053 XML. Future-proof your banking integration before the 2027 migration deadline.

Why convert MT940 to CAMT.053?

SWIFT is deprecating MT940 in favor of ISO 20022 CAMT.053, with a migration deadline of 2027-2028. Banks and financial institutions worldwide are transitioning to the richer, XML-based CAMT.053 format. If your systems still consume MT940, now is the time to start migrating.

CAMT.053 offers significantly more structured data: over 200 possible fields, proper XML validation, and standardized codes for transaction types, statuses, and references. Converting your existing MT940 feeds to CAMT.053 lets you build against the future standard today.

How it works

FinConvert’s parser extracts all data from your MT940 file — account info, balances, transaction details, and :86: information fields. The CAMT.053 formatter then maps this data into a valid ISO 20022 XML document conforming to the urn:iso:std:iso:20022:tech:xsd:camt.053.001.08 namespace.

The output includes proper BkToCstmrStmt structure with Stmt, Bal, and Ntry elements. Field mappings are documented in our spec-compliance matrix.

POST /v1/convert
Content-Type: multipart/form-data
file: statement.sta
to: camt053

This conversion is particularly valuable for testing CAMT.053 ingestion pipelines against real transaction data before your bank switches over.
