The International Swaps and Derivatives Association (ISDA) has urged firms to start preparing for the transition to revised foreign exchange (FX) derivatives definitions on November 22, 2027. The 2026 FX Definitions will become the market standard for all cleared and new non-cleared FX derivatives. Swift will stop supporting electronic confirmations using the 1998 definitions on that date, leaving firms that are not ready unable to use the service for those confirmations.
Published jointly by ISDA and EMTA in March 2026, the definitions replace the 1998 FX and Currency Option Definitions and consolidate subsequent supplements into one framework, removing the need for separate master confirmation agreements. Changes include revised disruption events and fallbacks for deliverable transactions, integrated terms for non-deliverable transactions and a fully automated exercise method for deliverable FX options. The calculation agent standard is also aligned with other ISDA product definitions.
Firms should assess the effects on confirmation processes, systems and data, and determine how bespoke terms in existing master agreements or master confirmation agreements will be treated. Preparation requires coordination across legal, operations, technology and front office teams. Firms should establish implementation dependencies with Swift, clearing houses and settlement systems, while ensuring clients and counterparties understand the changes and timetable. ISDA has published supporting resources, including an implementation roadmap, mapping materials and annotated confirmation templates.
