In a derivatiViews post, International Swaps and Derivatives Association Chief Executive Officer Scott O’Malia highlights the publication of the 2026 FX Definitions, produced jointly with the Emerging Markets Traders Association, as an update to the 1998 standard definitions for FX transactions to reflect changed market practice, regulation, events and technology. The 2026 FX Definitions retain elements of the 1998 framework but consolidate ISDA and EMTA documentation published since 1998 into a single integrated document and remove the need for separate master confirmation agreements (MCAs). They are also available digitally on ISDA MyLibrary, with tools to navigate and compare versions as future updates are made. Technical changes include revised disruption events and fallbacks for deliverable transactions, incorporation of EMTA template terms and market practices for non-deliverable FX, new provisions for calendar adjustment events, and calculation agent standards aligned with the 2021 ISDA Interest Rate Derivatives Definitions. Implementation is targeted for November 2027, supported by an implementation roadmap and a brochure summarizing key updates, with additional materials to be published in the FX Definitions Update InfoHub in the coming months.
