ISO 20022 & MX migration advisory

Overview

Run Ventures helps banks and investment banks plan their route through the shift from MT to ISO 20022 MX. We advise on migration strategy under the CBPR+ program, on running MT and MX in coexistence during transition, and on the mapping, translation and truncation issues that arise when richer, structured data meets legacy systems and downstream applications.

Our consultants support gap analysis against current message flows, testing and validation of MX formats, and the operational and staff readiness work that migration programs often underestimate.

Because ISO 20022 touches core banking, compliance, reconciliation and reporting far beyond the messaging layer itself, Run Ventures works across these functions to help clients capture the benefits of structured data rather than simply replicate MT in a new format.

What we do

• Migration strategy under CBPR+

  Planning the route from MT to MX for cross-border flows, sequenced against your counterparties and systems.

• Coexistence

  Running MT and MX in parallel during transition without losing data or control along the way.

• Mapping, translation & truncation

  Finding where richer, structured data meets legacy systems and downstream applications — and where it gets truncated.

• Testing & readiness

  Gap analysis against current message flows, MX testing and validation, and the operational and staff readiness work programmes often underestimate.

Beyond messaging

The migration reaches far past the messaging layer. Structured ISO 20022 data has to land in:

• Core banking, where structured data has to be stored and used, not flattened back into free text.
• Compliance, with screening and controls that work on richer, structured party data.
• Reconciliation, where matching and investigations depend on references surviving end to end.
• Reporting, built from the data the message carries.

Where an MT103 packs data into a handful of text fields, a pacs.008 breaks it into named, nested elements. The mapping between the two is where data is gained, and where it can be lost again.

Coexistence

During coexistence, the same payment can travel as MT on one leg and MX on the next, and every translation between the two is a point where structured data can be flattened. Truncation risk arises when structured party data passes back through MT-era systems or downstream applications that cannot hold it.
