ISO 20022 XML Message Support

ISO 20022 is a global standard for structured financial messaging, widely used across payments, securities, and clearing workflows. Many regulated firms need to ingest, validate, and transform ISO 20022 XML messages to support downstream operational processes, data governance, and reporting requirements.

REGREP provides ISO 20022 XML Message Support to help organisations process selected ISO 20022 message types in a structured and controlled way—enabling reliable parsing, validation, and mapping into internal data models used for regulatory and operational workflows.

This capability is designed as a messaging and data-processing component within REGREP’s broader regulatory reporting infrastructure.

REGREP’s ISO 20022 XML Message Support enables organisations to:

• Ingest ISO 20022 XML messages from upstream systems or providers

• Parse and normalise message data into structured internal representations

• Validate XML structure and key data constraints (where applicable)

• Transform and map message fields into downstream data models used for operational and reporting processes

• Support controlled, repeatable processing across environments and reporting cycles

This capability focuses on message processing and data readiness—not on replacing transaction processing systems.

ISO 20022 is a large and evolving standard with multiple message families. REGREP support is delivered with defined scope based on the ISO 20022 message types and business use cases relevant to your implementation.

Current ISO 20022 support typically includes:

• Processing of selected XML message categories used in operational and reporting-relevant workflows

• Structured parsing and mapping into REGREP’s data models

• Validations that support reliable ingestion and transformation

Coverage is confirmed per implementation based on:

• Message family and variant

• Required fields and mappings

• Validation requirements

• Integration points and target data models

Additional message coverage can be extended over time as new use cases and message families are introduced.

ISO 20022 XML Message Support is commonly used to:

• Standardise inbound financial message data for downstream controls and reporting processes

• Reduce manual transformation and inconsistent XML handling across systems

• Improve auditability of message ingestion and transformation steps

• Enable integration patterns where ISO 20022 messages feed internal data platforms or regulatory reporting workflows

This capability acts as a data ingestion and transformation layer that can support multiple workflows and solution areas, including:

• Regulatory data processing pipelines

• Validation and data quality controls

• Cross-system integration where ISO 20022 messages are a primary source of structured input

REGREP does not provide regulatory approval or compliance certification. ISO 20022 XML Message Support is provided as a technical capability to support operational and reporting implementations.
