Using ISO 20022 to Modernize
Payment Formats
Orlando Santos, Payrailz
So what is ISO 20022?
• ISO 20022 is an ISO standard for electronic data interchange between financial institutions. It describes a metadata repository containing descriptions of messages and business processes, and a maintenance process for the repository content. The standard covers financial information transferred between financial institutions that includes payment transactions, securities trading and settlement information, credit and debit card transactions and other financial information. A (global) messaging standard for standards.
• The repository contains a huge amount of financial services metadata that has been shared and standardized across the industry. Underlying all of this is the ISO 20022 metamodel - a model of the models. The first syntax supported for messages was XML Schema, and JSON is now supported.
• ISO 20022 is widely used in financial services. Organizations participating in ISO 20022 include Nacha, Afinis, FRB, TCH, Visa, Mastercard, SWIFT (US), and Payments Canada and nearly 100 other countries and hundreds of corporates worldwide.
And who is ISO?
• The International Organization for Standardization (ISO /ˈaɪsoʊ/) is an international standard-setting body composed of representatives from various national standards organizations.
• Founded in 1947, the organization promotes worldwide proprietary, industrial and commercial standards. It is headquartered in Geneva, Switzerland, and works in 164 countries.
• It was one of the first organizations granted general consultative status with the United Nations Economic and Social Council.
Managing the Standard
• The Standard is issued by ISO Technical Committee 68 (TC68), which is responsible for Financial Services in ISO.
• The Standard is managed by Working Group 4 (WG4), a sub-group of TC68 whose charter is "the management of ISO 20022".
• The Standard defines a Repository Management Group (RMG) composed of senior industry experts. It is the highest registration body.
• SEG Standard Evolution Group composed of industry experts in specific business domains of the financial industry
• SWIFT is the Registration Authority for ISO 20022. RA is the guardian of the ISO 20022 financial repository.
Adoption of ISO 20022
Advantages of ISO 20022
• ISO 20022 provides many characteristics supporting standardization, efficiency and interoperability.

ISO 20022 Messages Defined
Payments – Creditor/Debtor
• Pain.001 is a payments initiation message depicting a Credit Transfer (e.g., push payment)
• Pain.002 is a payments status report (e.g., acknowledgement)
• Pain.008 is a payments initiation message depicting a Direct Debit request (e.g., wire drawdown)
Cash Management - FI to Customer
• Camt.052 is an account status at a point in time (e.g., intra-day account position, entries)
• Camt.053 is an account statement at a point in time for booked entries (e.g., account position, credit and debits)
• Camt.054 is a notification of credit or debit entries (e.g., transaction details)

ISO 20022 Message Use Case
ISO 20022 and JSON
• In January 2018, members of the ISO 20022 RMG and TSG published a whitepaper on ISO 20022 and JSON.
• The purpose of this document was to help implementers in the financial services industry define RESTful Web Service Application Programming Interfaces (API) with resources represented in XML and/or JSON syntax, based on new and existing models in the Repository as defined by the international standard: ISO20022:2013 Financial services — Universal financial industry message scheme.
• This document was developed in response to a resolution by the ISO 20022 RMG indicating worldwide demand for help in understanding the use of ISO 20022 where JSON is used as syntax.

Leveraging ISO 20022 to Further Global Standardization - U.S. Payment Systems Landscape
ISO 20022 Stakeholder Group
• A U.S. ISO 20022 Stakeholder Group was formed a few years ago to determine if the U.S. payments systems should adopt ISO 20022 to remain competitive.
• The Group engaged an independent consultant to evaluate the business case for or against adopting the standard payment messages in the U.S. The consultant (KPMG) conducted the study and released its report in April 2014. It concluded that while there was not a compelling financial business case at this time for adoption, there were strategic reasons. Strategies to support the strategic reasons include education, assessment of the value proposition and timing for ISO 20022 domestic and cross-border payments for Wire and ACH, along with ISO 20022 being considered as the standard messaging formation for new products and services.

Integration into the ACH Network
ACH
• Integration involves developing tools and solutions that allow ACH users to leverage the ISO 20022 payment message standard for both electronic payments initiation and remittance without making changes to the current U.S. ACH formats and with the support of the Nacha Operating Rules.
Migration of the Hi-Value Payment Systems (Fedwire and CHIPS)
Wires
• Migration involves replacing the proprietary message formats for the Fedwire Funds Service and the CHIPS wire transfer system with message formats based on a global standard. This can improve payment processing efficiency and promote interoperability among high-value payment systems around the world.
Collaboration
• SWIFT will facilitate an industry migration of cross-border payments and cash management messages (MT categories 1, 2, and 9) to ISO 20022. The start date is aligned with the high-value payments systems in the Eurozone currently scheduled for November 2021, which will be a similar timeframe and approach to the U.S. and UK payment market infrastructures.
• Nacha continues to work with high-value wire operators to try to ensure that the ACH ISO mapping and remittance information is as consistent as possible.

Changes to legacyproprietary format to:• Prepare for & simplify
the migration to the ISO 20022 format
• Align with the SWIFT 2020 changes
• Migrate Fedwire Funds Service participants in waves over 12 to 18 months to send and receive ISO 20022 messages that have fields and character lengths that are comparable to the legacy format.
• The Fedwire Funds Service will translate the legacy format to ISO 20022 and vice versa when necessary to accommodate Fedwire senders and receivers that are not using the same format.
Enable participants to send optional enhancements.
Fedwire Funds Migration Takeaways
1. Collaborate with management/staff and external partners on migration plan to support phased implementation.
2. Internal assessment to identify needed changes to other tools that may be linked to wire process.
3. Development of educational plan for staff to ensure adequate awareness and knowledge to support organization’s migration activities.
4. Periodic access of Fedwire ISO 20022 implementation center web site (www.FRBService.org) and participation in educational events to stay abreast of latest developments and support organization’s migration strategy.
5. Materials are also published on SWIFT MyStandards.
CHIPS Migration
CHIPS Migration – Message Flow
CHIPS Migration Takeaways
1. TCH has published CHIPS phase 2 MUGS on SWIFT My Standards and the CHIPS Proprietary Legacy Phase 1 Readiness Implementation Guide is available to Participants directly via regulator communications channels.
2. Common CHIPS and Fedwire customers (Testing) - shared customers of both CHIPS and Fedwire have requested testing schedules from both CHIPS and Fedwire be optimized to reduce the pain points of having to complete an entire system restore when switching from one phase code bases to another between CHIPS and Fedwire.
a) Example: if both CHIPS and Fedwire are allowing their banks to test their ISO 20022 phase 2 codebase on a Tuesday in their respective test environments, the banks can test that day both CHIPS and Fedwire with less effort than if Fedwire were having Phase 1 testing that day and CHIPS having their legacy code testing that day. Alignment of testing schedules reduces the negative impact to the common customers. At this time, Fedwire and CHIPS systems are NOT integrated for any type of end-to-end testing.
b) TCH and Fed agreed to align testing schedules where possible.
c) Fedwire and CHIPS are hopeful of a October 24, 2020 test where both Fed and TCH will be testing their ISO 20022 phase 1 code and USING THE SAME SYSTEM DATE.
CHIPS Migration Takeaways
3. CHIPS and Fedwire are working together on migration of our common customers on to the Phase 2 ISO 20022 code bases.
4. Interim Translation – During the Phase 2 migration phase, CHIPS will have a seamless translation and mapping utility to allow our banks to translate between ISO 20022 and legacy and vice versa as banks are being migrated to ISO 20022.
