ISO 20022 - The new language of payments

ISO 20022 is a flexible standard for financial messages that enables interoperability between financial institutions, market infrastructures and the Banks’ customers. All banks must be ready to support the new language/standard to continue processing payments and customers should also prepare for changes.

The ISO 20022 standard supports the inclusion of richer, better structured transaction data in payments messages, and aims to deliver a better customer experience by enabling less manual intervention, more accurate compliance processes, higher resilience, and improved fraud prevention measures.

ISO 20022 adoption will provide benefits to the entire payments ecosystem i.e. Banks, Market infrastructures and to the Banks customers:

• Rich structured party data and increased field size will provide greater levels of transparency and create efficiencies by reducing delays caused due to unstructured, incomplete, or inconsistent data.
• By adopting dedicated returns and investigation messages and using standardized return codes, the current delays in applying returned funds back to the customers and responding to inquiries from other Banks will be drastically reduced.
• By maintaining dedicated reference fields that remain unaltered in the end to end payment journey and introducing structured remittance data, customer’s reconciliation capabilities will be augmented.
• Greater message harmonisation across the entire payments industry, with a universal message type for all payments will help integrate with many more schemes on a faster basis.

ISO 20022 adoption will take place over multiple years. Payment Market infrastructures (PMIs) of all major currencies are either live or in the process of adopting ISO 20022 by November 2025 for cross border payments. SWIFT has published a roadmap to migrate the existing message type 1,2,& 9 series which began in March 2023. Adoption plans are still evolving in each market and further clarity will be provided over time.

Adoption by major Real Time Gross Settlement (RTGS) market infrastructures/currency is currently planned as follows:

SWIFT plans to migrate all Customer and Inter-bank payments, as well as related advice and statement messages (the MT1xx, MT2xx and MT9xx series of messages).

HSBC is actively involved with SWIFT and the different market infrastructures that are migrating towards ISO. HSBC has successfully enabled its global network to receive and forward SWIFT CBPR+ messages in all of its 50+ locations and to exchange ISO messages in the newly migrated domestic markets. We will align ourselves with the market requirements and delivery timelines set by different market infrastructures and ensure we are well placed to comply with the adoption strategies set forth by the market infrastructure.

HSBC’s adoption strategy will be driven by two different approaches:

1. Markets with domestic migration announced
   ISO enablement of SWIFT cross-border payments is prioritised with domestic ISO migrations in HSBC markets. This is targeted to enable ISO for both domestic and cross-border payments together for customers to choose to adopt in one go.
2. Markets with no domestic migration announced
   The approach is to complete SWIFT cross border traffic migration in all countries and be compliant by November 2025. If a market infrastructure announces a domestic scheme migration before 2025, our current migration strategies are flexible enough to adapt accordingly.

The common adoption strategies are:

• ‘Like for like’, where the message format will be replaced from MT to ISO 20022 XML format that has comparable elements and character lengths to the existing SWIFT MT messages.
• ‘Full/enhanced ISO’, where additional and enhanced existing elements are available. In order to ensure consistent usage and inter-operability, guidelines are defined by the industry.

Two guidelines are available for the payment market infrastructures:

1. High Value Payments Plus (HVPS+) market practice guidelines followed by certain Market infrastructures
2. Cross Border Payments and Reporting plus (CBPR+) guidelines. The CBPR+ group are experts nominated from the SWIFT community tasked with developing usage guidelines for ISO implementation by Banks for SWIFT cross-border payments.

While HVPS+ and CBPR+ are almost fully aligned with a few minor differences, HSBC will provide updates to the possible impacts they may have on our customers in the respective markets.

We have created readiness handbooks to support our customers through the transition to ISO 20022, highlighting the significant changes this will bring across the payments industry, how and why these changes will happen, and the benefits they can bring.

* Also includes NBFIs sending instruction via SWIFT

As published in SWIFT’s connectivity guidance document it is mandatory that all Banks are required to upgrade their messaging interface to support InterAct (store-and-forward) by 20 March 2023. Institutions can also define the channel and format preferences for the transactions they receive through SWIFTs Transaction Manager (TM) platform. SWIFTs TM platform will ensure interoperability between users of different data formats and connectivity channels.

Here are some further considerations that banks should be looking at:

• Industry Testing: Get ready to participate in industry testing as mandated by market infrastructures and SWIFT. If you use another bank for clearing, please reach out to that bank
• Process & Systems: Have processes and systems geared up to fulfil your Sanctions and AML controls based on new party fields in the chain
• Archive Data: Ensure that you are able to archive the rich ISO payments data as per your country regulations
• Data Availability: Create solutions to make enriched data available to your customers
• Structured Data: Start preparing to provide structured Name and address information for your customers(Debtors)
• Training: Training and awareness of internal staff on the new language

We recommend our Corporate customers understand the potential of XML for your business and make the most of the opportunity.

Here are some considerations for Corporate customers:

• Preparing for the future: A few market infrastructures already mandate corporates to provide XML as a standard while communicating to their Banks. With the increased adoption of ISO 20022 as a standard by SWIFT and major market infrastructures worldwide it is possible that more market infrastructures may recommend ISO as a messaging standard for communicating. Considering this in your technology plans will support preparation for these requirements from market infrastructures in the future.
• Structured Data requirements: Market infrastructures and Clearing schemes have introduced new data requirements for party information. These include fields like creditor, ultimate debtor, initiating party, and ultimate creditor that will require corporates to provide to the bank in a structured or hybrid manner. HSBC will soon be providing communications on the required changes. We strongly recommend you start looking at the data that is provided to HSBC and work closely with your Enterprise Resource Planning (ERP) and Treasury Management System (TMS) providers to start making required updates to comply to the new industry requirements.
• Capitalising on rich standards: ISO offers multiple benefits that will help streamline end to end processing. Early adoption will allow you to capitalise on the information that is supported in remittance information and enhanced end to end references, which will be available through ISO based cash management(camt) statements/advises.

HSBC is eager to work with our clients to assist in their migration to ISO 20022. HSBC has been a strong advocate for XML and a key driver in the evolution of the ISO 20022 XML standard. Customers will be able to leverage the experience we have gained from previous implementations.

As market infrastructures finalize specifications, our team of experts will reach out to you and provide the details of changes to our existing offerings, and information on any new value added services that we will be able to offer leveraging the richer data elements that ISO 20022 offers.
