About the Harmonisation Charter

ISO 20022 is emerging as the preferred choice of messaging standard for market infrastructures around the world. As ISO 20022 implementations proliferate, variability in the ways in which ISO 20022 is deployed, in terms of message versions, market practice rules and release cycles, threatens to undermine its value.

The success of the ISO 20022 harmonisation programme depends crucially on engagement from the market infrastructures community. If your organisation or your community is interested in receiving additional information please contact your account manager or regional representative.

ISO 20022 Implementation Strategies

Over the last 10 years, ISO 20022 has emerged as the key global standard for financial market infrastructures (FMIs). There are various drivers for these initiatives and ISO 20022 is typically chosen for a combination of reasons. Today, several FMIs have successfully migrated/implemented ISO 20022 and others have declared implementation timelines for the years ahead. This paper draws on some of the experience gained by the industry; to understand what worked well or less well and to distil some high level best practice advice.

The harmonised approach to ISO 20022 adoption

Payments and securities market infrastructures have led their industries in the adoption of the ISO 20022 international messaging standard. Since 2015, a growing number have endorsed an ISO 20022 Harmonisation Charter to ensure implementations of ISO 20022 remain consistent for users of market infrastructures.
