Connect on Linkedin Frequently Asked Questions + EXPAND ALL What is ISO 20022 and why does it matter for payments? + ISO 20022 is a global messaging standard that standardizes how financial data is structured and exchanged across payments, treasury, and clearing systems. It enables richer, more detailed payment data, improving transparency, automation, and interoperability across the financial ecosystem. What is ISO 20022 migration readiness? + ISO 20022 migration readiness refers to an organization’s ability to transition from legacy payment formats to ISO 20022-compliant messaging. This includes assessing systems, data structures, and processes to identify gaps, ensure compatibility, and prepare for regulatory deadlines. What do financial institutions need to do to prepare for ISO 20022? + Organizations must evaluate current payment systems, update data models, implement ISO 20022 message formats (such as MX), and conduct end-to-end testing. Preparation also includes operational changes such as workflow updates, reporting adjustments, and staff training to support the new standard. How does ISO 20022 migration impact operations and risk? + ISO 20022 migration introduces changes to payment processing, data handling, and system interoperability. Without proper planning, organizations may face data loss, processing errors, or disruptions. A structured migration approach helps reduce operational risk and ensures continuity. How does Protiviti support ISO 20022 migration? + Protiviti supports ISO 20022 migration through readiness assessments, solution design, implementation guidance, and testing support. Our approach helps organizations reduce risk, improve data quality, and ensure a controlled transition aligned with regulatory requirements. Can ISO 20022 migration be tailored to different organizations? + Yes. ISO 20022 migration approaches vary based on system complexity, internal capabilities, and timelines. Organizations may require full program leadership, blended delivery models, or targeted support during key phases such as testing and go-live.
