SOURCE MESSAGES AND SAMPLES

Use the official definitions for both sides of the translation and inspect the original teaching samples before implementing a mapping.

An XSD checks XML structure. A usage guideline adds profile rules, conditional fields, code restrictions, and business controls. XSD-valid does not mean scheme-compliant.

XSD + definitionBase ISO 20022current

ISO 20022 message definitions and XSDs

Choose the exact message definition in the official catalogue. The base XSD checks XML structure; it does not prove compliance with a scheme profile.

Nothing selected yet — try the amount field on either side and watch one MT field become two structured MX elements.

Sources for this mapping3
  1. Market practice

    Payments Market Practice Group market practice documents ↗ — Payments Market Practice Group

    Global market practice for payment messaging, including guidance on structured party data, cover payments, and the coexistence of MT and ISO 20022 formats. · Checked 2026-07-12

    The PMPG publishes individual papers via the Swift website; its recommendations are market practice, not binding scheme rules, and adoption varies between institutions.

  2. Official requirement

    Swift Standards MT (annual standards releases) ↗ — Swift

    Defines the MT message standards (including MT101, MT103, MT202/202 COV, and the MT9xx statement messages) exchanged over the Swift FIN network, maintained through annual standards releases. · Checked 2026-07-18

    Full field-level specifications live in the Swift Knowledge Centre User Handbook behind a swift.com login. Coexistence for in-scope FI-to-FI payment instructions ended on 22 November 2025, but treatment differs by MT: some instructions are NAKed and selected messages can enter temporary, chargeable contingency conversion. Reporting, initiation, investigations and correspondence follow separate roadmaps.

  3. Simplified educational illustration

    Payments Signal editorial teaching models — Payments Signal

    This site's own simplified teaching models. · Checked 2026-07-12

    What this simplifies: Rows focus on lifecycle meaning and omit usage-guideline conditionals.

    Used wherever diagrams, scenarios, figures, or example values are didactic constructions rather than sourced facts; every such use carries a simplifications disclosure. All people, companies, banks, and list entries in examples are fictional.
