ANNA and GLEIF Join Forces on ISIN-to-LEI Mapping Initiative

ISIN is the recognized global standard for unique identification of financial instruments such as securities. LEI connects to key reference information that enables clear and unique identification of legal entities participating in financial transactions—for example, the issuers of securities. The new, global initiative will map new and legacy ISINs to their corresponding LEIs. By linking the two ISO standards together, firms will be able to aggregate the data required to gain a clear view of their securities exposure within a given issuer and its related entities. Once implemented, the ISIN-to-LEI mapping table will be made freely available to all without restriction on both the GLEIF and ANNA websites.

From the GLEIF perspective, it is important to highlight that while the linking of ISINs and LEIs has been mandated by some regulations, GLEIF seed this new initiative as beneficial to the entire global market. It is the first big step in having the tools available for aggregation of the data necessary to assist with risk and exposure management.
