ISO 20022 Migration Frequently Asked Questions

1: Will I need to migrate to ISO 20022?

Whether you need to migrate depends on your organization type:

• For Corporations (non-financial institutions):

  • If you have a regular corporate BIC (Corp Category) you are not part of the mandatory migration requirement.

  • Your banking partners may be making changes to the files they are sending or receiving. Please reach out to your banks to see if it can impact your integration and business.

• For Financial Institutions:

  • If you hold a financial BIC (SUPE - Supervised) or are involved in interbank settlements using MT103 and MT202 messages via SWIFT FIN, you are required to migrate by November 2025.

  • All financial institution categories are impacted except for the CORP (Corporate) category.

3: What is ISO 20022?

ISO 20022 is an international standard for electronic data interchange between financial institutions. It's a more structured, data-rich messaging format that uses XML and is designed to improve the quality of financial messaging by providing:

• Enhanced data capabilities

• Better straight-through processing

• Greater interoperability across payment systems globally

• Improved compliance with regulatory requirements

• Richer remittance information

5: What are the benefits of ISO 20022 migration?

Migrating to ISO 20022 offers significant benefits for financial institutions and their clients. This global messaging standard enables richer, more structured, and more consistent data across payment and financial messages, leading to improved automation, enhanced compliance, and faster reconciliation. With ISO 20022, organizations can achieve greater interoperability between domestic and international systems, reduce manual intervention, and lower the risk of errors or fraud.

Benefits include:

• Enhanced data quality and richness

• Improved straight-through processing rates

• Better reconciliation capabilities

• Reduced payment failures and returns

• Enhanced compliance and fraud prevention

• Greater standardization across payment systems globally

• Future-proofing your payment infrastructure

2: How will ISO 20022 affect my payment operations?

Corporations may experience:

• Changes in payment file formats required by banks

• Enhanced remittance information capabilities

• New requirements for structured addressing

• Potential need for system upgrades or changes

• Improved payment tracking and visibility

• Better reconciliation capabilities

4: Is the FIN+ service accessible to corporations for reporting?

Yes, Swift will open the FIN+ channel for Corporations in November 2025, but will depend on banks to further Camt053 V8 (ISO 20022). Contact your bank to make sure that it is offering Camt053 V8 (ISO 20022).

6: How are other countries handling the ISO 20022 migration mandates?

Because the SWIFT Cross-Border Payments and Reporting (CBPR+) affects all countries using SWIFT for cross-border payments, many countries have completed their migration and/or have multiple payment systems at different stages of ISO 20022 implementation. The level of ISO 20022 implementation varies, with some countries implementing basic functionality first and planning enhanced data capabilities later.

For the most up-to-date and official status, industry sources such as the BIS Fostering ISO 20022 harmonisation report and SWIFT’s ISO 20022 site provide detailed tables for reference.

8: How will ISO 20022 affect my bank reporting/statements?

For corporations:

• Bank statement migration to ISO 20022 (MT940 to Camt.053) does not have a strict deadline yet.

• Your banks may migrate at different times based on their own schedules.

• You may receive statements in both formats during the transition period.

• Work with your treasury system provider to ensure they can process both formats.

10: I am using an interbank Settlement format for my regular third party payments. Am I subject to the migration? 

Contact your bank because they might require a format from your corporation. Ask about MT103 and whether the bank will accept the pac.008.001.08 format?

2: What payment types are in the migration?

Interbank settlement (from a financial BIC to another financial BIC)

4: Will financial institutions need to migrate their reporting messages (MT940, etc.)?

Not immediately:

• SWIFT has removed the November 2025 deadline for reporting message migration.

• Financial institutions can continue using MT940 via FIN after November 2025.

• They can choose to continue with MT940/FIN or migrate to Camt.053.001.08/FIN+.

• Both channels may be used depending on counterparty readiness.

• SWIFT has not defined a new date for mandatory reporting migration to XML.

6: Are there size limitations for statements sent via FIN+?

Yes. While the maximum size is larger than for FIN, Camt.053.001.08 transmitted via FIN+ cannot exceed 256 KB (approximately 80 transactions). Larger statements will be sent in multiple pages.

8: Are structured addresses mandatory in pacs.008 and pacs.009?

SWIFT is introducing hybrid addresses in November 2025:

• The minimum requirement will be to provide the town name and country for debtor and creditor.

• The rest of the address can be provided in structured tags or unstructured Address Lines.

• Fully unstructured addresses will be forbidden after November 2026.
  
  

2: How can testing be organized?

Testing can be done via:

• SWIFT MyStandard testing platform

• Direct testing with counterparty banks

• Working with your payment service provider to arrange testing

4: What is the difference between FIN and FIN+?

• FIN is the traditional SWIFT protocol used for MT messages (like MT103, MT202, MT940).

• FIN+ is the newer protocol designed for ISO 20022 XML messages (like pacs.008, pacs.009, camt.053).

• After November 2025, interbank payments must use FIN+ with ISO 20022 formats.

• FIN+ supports larger message sizes and more structured data.

6: How does ISO 20022 impact cross-currency transactions?

Cross-currency transactions will benefit from:

• Enhanced currency and exchange rate information

• Clearer indication of charges and fee structures

• Better transparency throughout the payment chain

• Improved reconciliation capabilities due to richer data

• More consistent handling across different payment systems

Financial institutions involved in cross-border payments or interbank settlements will need to migrate to ISO 20022 to continue operations after the SWIFT deadline in November 2025.
