Financial institutions are facing increasing pressure to modernise payments infrastructure as global demand for instant transactions grows. Within this environment, ISO 20022 AML compliance is emerging as a critical priority for banks, payment providers and FinTech firms operating across borders.
According to RelyComply, with consumers and businesses expecting faster payments and regulators requiring stronger oversight of financial crime, institutions are being pushed to upgrade systems that were never designed to handle real-time monitoring.
Industry momentum suggests that the shift is already underway. Nearly 95% of financial services firms are either modernising their payment infrastructure or planning to do so. These upgrades are widely seen as necessary to support real-time AML monitoring while also meeting customer expectations for seamless and immediate transactions. Without this modernisation, financial institutions risk falling behind both technologically and from a regulatory standpoint.
ISO 20022 represents a significant development in the evolution of payment standards. While ISO 27001 has long provided the governance framework for securing sensitive transaction monitoring data, ISO 20022 focuses on improving the quality and structure of payments information itself. For more than two decades, the standard has existed as a framework for financial messaging, but its practical benefits are becoming increasingly clear as institutions adopt it to strengthen fraud prevention and AML controls. Legacy infrastructure often struggles to process structured payments data effectively, making it difficult to perform real-time monitoring or protect customers in an environment where cybercrime continues to escalate.
For organisations seeking to balance innovation with regulatory obligations, certifications such as ISO/IEC 27001:2022 demonstrate strong commitments to data protection and financial crime prevention. Companies operating under such standards, including RegTech providers like RelyComply, can show that they safeguard sensitive data while enabling FinTech growth within tightening compliance frameworks. In practice, this can help firms innovate without allowing data governance requirements to slow down operational progress.
The importance of ISO 20022 becomes even clearer when examining the current fragmentation of payment systems. Disconnected infrastructures, evolving regulations and inconsistent financial messaging standards create gaps that criminals can exploit. Cross-border payment environments are particularly vulnerable, especially as digital assets and new payment rails become more common. The G20 has repeatedly highlighted that the absence of consistent financial messaging standards remains a major obstacle to efficient and secure cross-border transactions.
Structured payments data lies at the core of ISO 20022’s value proposition. The standard introduces consistent message formats that include detailed remittance information, sender and recipient identification and purpose codes that clarify the underlying reason for a transaction. Embedding this information directly within payment messages significantly improves transparency and enables institutions to monitor transactions with far greater precision.
Adoption has accelerated following major changes to the global payments ecosystem. On 22 November 2025, the SWIFT MT and ISO 20022 coexistence period ended, making ISO 20022 the default messaging format for cross-border payments on the SWIFT network worldwide. This milestone has pushed many institutions to complete migration efforts and update internal compliance systems capable of interpreting richer payment data.
For payment service providers (PSPs), international banks and FinTech firms, the benefits of richer structured data extend directly to AML operations. When transaction monitoring data is fragmented across legacy systems or affected by poor data quality, the effectiveness of AML controls is compromised. ISO 20022 improves this situation by tagging information in standardised formats, allowing compliance teams to conduct more accurate analytics and detect risks that may otherwise remain hidden.
Structured data also enables the development of more advanced automated compliance systems. As regulators introduce real-time payment requirements such as the European Union’s Instant Payments Regulation, institutions are increasingly expected to conduct screening and monitoring checks instantly. Around 80 instant payment schemes are already operational worldwide, creating additional pressure for firms to automate compliance workflows.
In this context, AI-driven RegTech platforms are becoming increasingly valuable. When working with structured payment data, these systems can conduct AML checks more efficiently, identify suspicious patterns faster and reduce the number of false positives that often burden compliance teams. Structured sanctions screening data also enables institutions to build comprehensive risk profiles for individuals or entities, supporting more accurate entity resolution and risk assessment.
Despite its advantages, ISO 20022 is not a universal solution for all AML challenges. Differences between payment providers’ infrastructure can create inconsistencies in how the standard is implemented. Richer data requires advanced technology capable of analysing and acting on it in real time. Without the necessary infrastructure, the full benefits of ISO 20022 cannot be realised across fragmented payment ecosystems.
Adoption is still ongoing globally. While the coexistence phase has ended, not every financial institution has fully completed migration efforts. In fact, only around 80% of Real Time Gross Settlement (RTGS) systems were expected to have implemented ISO 20022 by the end of last year. Achieving true harmonisation therefore depends on consistent implementation across all institutions participating in global payments networks.
Cost pressures also remain a major obstacle. Many payment companies continue to allocate as much as 60% of their IT budgets to maintaining and upgrading legacy systems. These expenses can slow down migration projects, particularly as payment infrastructures grow more complex and regulatory expectations continue to rise.
The relationship between ISO 20022 and ISO 27001 highlights how different standards work together to strengthen financial crime prevention. ISO 20022 focuses on improving the quality and structure of payment data used for AML analysis, while ISO 27001 ensures that the information itself is properly governed, audited and protected from misuse or breaches. Together, they provide the foundations for more effective identity verification, transaction monitoring and risk management frameworks.
RegTech providers certified under ISO/IEC 27001:2022 can play a crucial role in this environment. Their platforms are designed to process structured payments data while maintaining strong security controls, allowing financial institutions to conduct sanctions screening and AML reporting safely without introducing friction into payment flows. For businesses and customers alike, this combination of faster payments and stronger protection is becoming increasingly important.
