ANNA-DTIF Task Force Updates DTI-ISIN Guide with New Criteria for FFG Allocation

The ANNA-DTIF Task Force, in collaboration with industry stakeholders, has released an updated version of the DTI-ISIN Guide. This latest update focuses on revising the criteria for the allocation of DTI Functionally Fungible Groups (FFGs) and their relationship to XT ISINs, aiming to enhance clarity and consistency in the identification process.

The updated criteria will help improve the accuracy and reliability of FFG allocations, addressing feedback from market participants and aligning with best practices. The task force has ensured that the new guidelines reflect the evolving needs of the industry and support the continued development of transparent, standardized systems for financial instrument identification.

The task force has agreed that XT ISIN fungibility and FFG DTI inclusion rules shall follow the same criteria. This will ensure that:

1.            Any individual DTI is linked to a single ISIN; and

2.            ISIN is linked to a single FFG DTI (and DTIs within that group).

The updated XT ISIN Implementation Guide and updated mapping table are now available on the ANNA and DTIF websites (links).

The task force encourages all stakeholders to review the changes and provide any further feedback.
