Please note that ISDA no longer supports the 2006 ISDA Definitions – see ISDA’s statementfor further information.
This page will be updated on a regular basis as relevant information becomes available and will serve as a repository for information from ISDA relating to the 2021 Interest Rate Derivatives Definitions.
On June 11, 2021, ISDA published the first version of the 2021 ISDA Interest Rate Derivatives Definitions, following a root and branch review of the current market standard definitional booklet for the interest rate derivatives market – the 2006 ISDA Definitions.
The 2021 Definitions have retained much of what worked well under the 2006 Definitions, but in some areas have been substantively updated to better reflect modern market practices, improve clarity and to make transactions more robust in the face of contingencies such as market closures and benchmark related events. An article discussing the benefits of the new 2021 ISDA Interest Rate Derivatives Definitions is available here: IQ: ISDA Quarterly, February 2021 – Transformational Change. A Japanese translation of this article is available here.
On the October 4 implementation date most major global CCPs adapted their rulebooks to adopt the 2021 Definitions and adoption in the non-cleared market commenced with many major market participants switching to the new definitions by default or upon request. ISDA anticipates rapid and widespread adoption in the rest of the non-cleared market. ISDA continues to work with its member working groups to identify and resolve issues relating to the adoption and implementation of the 2021 Definitions and to draft subsequent versions of the 2021 Definitions. Versions 2, 3, and 4 of the 2021 Definitions were published on September 30, November 10, and December 16 respectively and were principally intended to maintain alignment with the 2006 ISDA Definitions.
2. Accessing the 2021 Definitions on the MyLibrary Platform
The 2021 Definitions also represent ISDA’s first natively digital definitional booklet, published exclusively on the ISDA MyLibrary platform. This enables users to view a consolidated version of the definitions, to see how they have changed over time and provides access to enhanced user facilities such as hyperlinking to definitions, bookmarking and additional resources. For more information on how to access the MyLibrary platform, please contact firstname.lastname@example.org. A fact sheet on MyLibrary is available here. A webinar on the 2021 Definitions and MyLibrary can be seen here.
The ISDA 2021 Definitions Implementation Subgroup is meeting on a weekly basis in the run up to October 4, 2021, to identify and resolve issues relating to the adoption and implementation of the 2021 Definitions. The sub-group is open to ISDA members and, given its focus on operational implementation, tends to be attended by operations staff from member firms. If you are interested in participating in the Implementation Sub-group, please contact email@example.com. Members of ISDA can access recordings of the Implementation Sub-group calls below.
Introduction to Implementation of the 2021 ISDA Interest Rate Definitions
On behalf of ISDA, consultancy firm Quorsus conducted several interviews across a cross-section of ISDA members to ascertain the steps firms are taking, or have identified as necessary, to implement the 2021 Interest Rate Derivatives Definitions. The Quorsus report, Implementation Interviews: Participant Recommendations, highlights suggested operational practices identified during the interviews to help firms in their preparations.
The phased approach to implementation of the 2021 Definitions means that some market participants will be ready to trade using the 2021 Definitions with their counter parties from October 4th while others will not be ready until a later date. In order to reduce the potential for breaks and in order to help facilitate a safe and efficient market, ISDA has agreed to post information regarding firms’ definitions preferences in a standardised format. ISDA takes no responsibility for the information any preference grid contains and makes no representation as to its accuracy or completeness. For a definitive understanding of a party’s definitional preferences, market participants should contact the relevant party. Contact details (to the extent they have been provided) can be found at the bottom of each preference grid. By accessing the information provided, users agree that they will not use the information for any anti-competitive purpose.
While the 2006 ISDA Definitions are amended by the publication of ‘Supplements’, component documents of the 2021 Definitions (such as the Main Book or Matrices) will be amended and restated in their entirety in new versions. Versions of each component document will be differentiated by number and date (eg, Main Book, Version 1, June 11, 2021 or Version 2, September 30, 2021). ISDA has also published confirmation templates for use with the 2021 Definitions.
ISDA has published the following releases of the 2021 Definitions:
June 11, 2021
September 30, 2021
November 10, 2021
December 16, 2021
