ISO 20022 migration in payments
The payments landscape in the United States is undergoing a transformative period driven by the adoption of new messaging standards and the growth of instant payment opportunities. Perhaps one of the most pivotal shifts is the transition of Wires to the ISO 20022 messaging standard. The standard has also been chosen for the FedNow Service, the Federal Reserve's new instant payments infrastructure.
This article explores the implications of ISO 20022 migration for financial institutions, particularly how such a data-rich, structured messaging standard aims to streamline payment processing. Additionally, we’ll outline the migration's key milestones and assess how stakeholders can navigate challenges and leverage emerging opportunities.
What is ISO 20022? Key milestones and understanding the new standard for payments
ISO 20022 is a global standard for financial messaging that supports the exchange of richer and more structured data within payment systems. Unlike the case with legacy formats, the additional information in ISO 20022 messages enables financial institutions to enhance payment processing in areas like compliance checking and fraud detection, improving the customer experience and outcomes. Financial institutions can streamline payment processes, increase automation, and reduce operational bottlenecks by adopting a single messaging format like ISO 20022.
The need for improved interoperability and enhanced data analytics capabilities has spurred a global push towards ISO 20022 adoption. A recent report by Celent stated that 83% of banks expect the pace of change to accelerate as the ISO 20022 implementation progresses, urging financial institutions to adopt the new ISO 20022 standard quickly.
The ISO 20022 timeline includes several key milestones. In the US, the Fedwire Funds Service transitioned in July 2025, aligning with the international SWIFT ISO 20022 migration deadline due in November.
When navigating the migration to ISO 20022, financial institutions need to address potential risks like truncation, which can occur when converting data-rich ISO 20022 messages to legacy formats. Financial institutions that fail to implement these measures risk operational disruptions, compliance breaches and missed opportunities for innovation and collaboration.
Understanding ISO 20022 and its impact on payments
The ISO 20022 format is designed to facilitate enhanced data capture and exchange between payment networks. Through ISO 20022 adoption, financial institutions can transmit richer, more standardized and comprehensive data crucial for improving interoperability and real-time payment processing.
It’s important to note that any institutions using message translators to transform between legacy formats and ISO 20022 risk data truncation and inconsistency, along with an ongoing maintenance challenge. As the ISO 20022 deadline approaches, the need for fully-integrated, native ISO 20022 systems grows. Additionally, financial institutions need to ensure all application programming interfaces (APIs), internal systems and fintech integrations are compliant, to avoid the risk of data loss and operational inefficiencies, or even failures. It’s not enough to just have the payment engine ISO-compliant. The potential gains are great – compliance with the ISO 20022 standard facilitates frictionless communication and interoperability between financial institutions, both domestic and across borders.
ISO 20022 migration implementation challenges
ISO 20022 migration presents significant challenges, particularly for financial institutions still reliant on legacy systems. To benefit from data-rich messaging capabilities, global payment systems are rapidly adopting the new messaging standard, but local variations in implementation are creating friction. Such discrepancies complicate message translation and increase the likelihood of data truncation or misinterpretation when messages are converted between proprietary and ISO 20022 formats; the situation is even more complex for cross-border payments involving multiple jurisdictions.
Financial institutions that don’t adopt ISO 20022-native systems may resort to tactical solutions. While these interim measures offer basic compliance, they often lack the capabilities to fully leverage the analytical and operational benefits of ISO 20022 implementation.
Financial institutions that fully embrace ISO 20022, however, can take advantage of this weakness and position themselves as strategic partners helping clients navigate the complexities of ISO 20022 migration. They can offer value-added services based on rich transaction data, such as advanced cash flow forecasting, working capital optimization and benchmarking services. In order to truly take advantage of these opportunities, financial institutions need to invest in the advanced data analytics capabilities required to fully exploit the ISO 20022 rich data. This may require partnering with fintech providers to access AI and machine learning technologies that can extract actionable insights.
ISO 20022 migration: Benefits for financial institutions
The transition to ISO 20022 presents a range of opportunities for financial institutions, including improved compliance and increased operational efficiency.
The structured data in ISO 20022 can be fed into AI and machine learning systems to improve the detection of complex anti-money laundering (AML) and fraud scenarios and reduce false positives. In addition, the standardization of data content enables more effective and automated processing, minimizing manual intervention and reducing payment exceptions. This ultimately accelerates transaction processing and enhances client service.
ISO 20022 also creates avenues for new revenue streams. Financial institutions can leverage data insights to develop advanced cash flow forecasting, working capital optimization and other personalized and enhanced services, transforming compliance-driven investments into value-added service offerings.

Finastra’s role in ISO 20022 migration
Finastra’s Global PAYplus solution and Payments To Go provide a comprehensive approach to ISO 20022 migration, offering end-to-end payment processing capabilities designed to handle structured and unstructured data. By integrating modern APIs and a microservice-enabled ISO 20022 data model, our payment hubs consolidate payments data into a single, standardized view, reducing operational complexities and ensuring steadfast compliance with ISO 20022 regulatory standards.
For over 30 years, we have delivered complex, mission-critical solutions to financial institutions of all sizes, including providing ISO-based clearings in the US, such as FedNow and The Clearing House Real Time Payments, for instant payments. We have also helped our clients transition from proprietary high-value payment message formats to ISO-based standards in various regions, including Europe and South Africa.
For instance, Vietcombank’s implementation of Global PAYplus enabled the bank to streamline its payment architecture, reduce costs and maintain data integrity throughout the payment lifecycle. The STP rate for domestic payments reached nearly 100%, and over 90% for cross-border payments. Moreover, our transformation capabilities ensure seamless data conversion between MX, MT and proprietary formats, mitigating the risk of data truncation and enabling complete data visibility across payment ecosystems.

The future of ISO 20022 payments: Beyond the migration
ISO 20022 is not merely a compliance requirement; it’s a foundational element for the next generation of payment systems. As digital payments grow, ISO 20022 will continue to support real-time payments, cross-border settlements and digital currencies, creating new possibilities for interoperability, data integration and analytics.
To future-proof their operations, financial institutions must consider implementing ISO 20022-native payment hubs capable of handling the increased volume and complexity of data. This approach not only ensures regulatory compliance but also enables financial institutions to monetize rich transaction data through advanced analytics and AI-driven insights.
