ISO 20022 & SWIFT MX Migration: PACS, CAMT, Payments & Treasury Operations

Introduction

ISO 20022 has become the global standard for financial messaging, fundamentally transforming the way financial institutions exchange payment, settlement, account reporting, and treasury information. The migration from legacy SWIFT MT messages to ISO 20022 MX messages provides richer, more structured, and more transparent financial data, while also introducing significant operational, technological, compliance, and data-management challenges.

This comprehensive 10-day training program provides participants with an in-depth understanding of ISO 20022 and SWIFT MX messaging, with particular emphasis on PACS and CAMT message families, correspondent banking, payment processing, treasury operations, MT–MX mapping and translation, data truncation, coexistence, compliance, risk, and operational migration.

The program combines conceptual knowledge with practical message analysis, real-world scenarios, case studies, and hands-on exercises using representative MT and MX message sets. Participants will develop the practical knowledge required to understand, manage, and support the transition from legacy MT messaging to ISO 20022 MX.
