ISO 20022 is the international financial messaging standard bringing richer and better-structured data to financial transactions. Its global adoption by payment market infrastructures and financial institutions, including in the U.S., represents a significant opportunity for enhanced payments efficiency and increased global interoperability. However, it will require concerted industry efforts to avoid misaligned implementations and inconsistent use of the standard that would undercut those benefits. This second article of our Harnessing the Power of ISO 20022 series explores some of the global efforts to align implementations and FRFS’ work in building on its initial investment in the standard.
CPMI Harmonised ISO 20022 Data Requirements
On Feb. 26, 2026, the Bank for International Settlements’ (BIS) Committee on Payments and Market Infrastructures (CPMI) published an update to its report on Harmonised ISO 20022 data requirements for enhancing cross-border payments (Off-site).
The original report, released in October 2023, was developed by a joint task force of the CPMI and the private-sector global Payments Market Practice Group. It set out 12 high-level “requirements” with detailed individual message data models to establish a consistent minimum set of data to be used in a cross-border payment transaction end to end. The CPMI “encouraged market participants to begin preparations to align with the harmonised ISO 20022 data requirements in earnest by end-2027 at the latest.”
Following the initial publication, the CPMI established the ISO 20022 Harmonisation Panel comprising a group of global payment practitioners to govern and maintain the requirements and data models through at least 2027. The 2026 revisions fall into three categories.
- Clarification of the data requirements to improve general understanding and aid with the correct implementation
- Minor revisions to data models that incorporate industry feedback, prepare for regulatory changes, more specifically, revision of the Financial Action Task Force (FATF) Recommendation 16 (the “travel rule”), and to leverage some of the richer data structures that were enabled in later versions of the core CPMI ISO 20022 message set
- Inclusion of two new ISO 20022 messages with detailed data models for payment investigations

FRFS and ISO 20022
FRFS, as a payments system operator, aligned its ISO 20022 implementations with the harmonised requirements released in 2023. In fact, when the Fedwire® Funds Service cut over to ISO 20022 on July 14, 2025, participants were able to utilize the CPMI payments data models for USD high-value wire payments immediately as part of our transition to ISO 20022. As we prepare for the Fedwire Funds Service November 2026 Release (Off-site), we will realign our initial implementation with the revised data requirements, including the rollout of the hybrid postal address format and the incorporation of the two payment investigation structured data models that were not available at time of our initial cutover. The Fedwire Funds Service was the first system globally to implement these new payment investigation messages as part of our efforts to not only improve the efficiency of payments but also streamline and automate the resource-intensive investigation processes.
Looking Ahead
FRFS will continue monitoring ongoing global alignment efforts and the evolution of ISO 20022. We are increasing our focus along three dimensions to reap the benefits of ISO 20022 beyond our initial implementation by:
- Focusing on the creation of a U.S. Payments Data Model: We approach the rollout of ISO 20022 holistically across the different payment systems that we operate. In collaboration with peer operators, standard-setting bodies and market practitioners, we strive towards defining a single, harmonized U.S. payments ISO 20022 data model. We are aligning the FedNow Service and Fedwire Funds Service implementations to incorporate best practices and enable the application of the CPMI harmonized data requirements.
- Enhancing Industry Collaboration: We are increasing our industry efforts to further leverage ISO 20022’s data rich capabilities and bring data-driven innovation to payments. One effort will zoom in on positioning structured data to improve end-customers’ payments automation and reconciliation processes. With an initial focus on instant payments, another work item will focus on defining a payment categorization scheme.
- Streamlining Maintenance Processes: In an ever more connected payments ecosystem, we are preparing for more regular ISO 20022 updates to protect interoperability as requirements and data models evolve because of:
- The ongoing evolution in the payments industry with the arrival of new technology and innovative solutions, often introduced by new (fintech) market entrants
- The changing regulatory environment
- The evolution of the ISO 20022 standard, as messages are maintained on a yearly basis</li
What to Expect Next?
The announcement of the CPMI’s revised Harmonised ISO 20022 data requirements for enhancing cross-border payments is only part of our ISO 20022 discussion series. Throughout 2026 we are also exploring:
- How ISO 20022 can be used by the payment industry to improve fraud detection and mitigation.
- How FRFS will maintain its ISO 20022 implementations through a structured change management framework.
