Thomson Reuters Resolves the MiFID II No LEI, No Trade Problem

Subscribe to our newsletter

Thomson Reuters has responded to the ‘No LEI, No Trade’ problem posed by Markets in Financial Instruments Directive II (MiFID II) with an LEI Profiling Service that allows users to identify LEI gaps that need to be closed before the January 3, 2018 deadline and check the data quality within their reportable client universes.

The profiling service is based on the Thomson Reuters Avox database, which maintains 100% Legal Entity Identifier (LEI) coverage based on daily updates from the Global LEI Foundation (GLEIF). Users of the service send their entities of interest to Thomson Reuters, which matches them against the LEI records stored in the Thompson Reuters Avox Database, and allows users to identify entities that have yet to request LEIs and, where LEIs exist, determine their status.

Benefits of the service include reduced cost and time as firms can focus on proactive client outreach for known entity record gaps rather than on reconciliation of internal content. The service will also help to track the thousands of LEIs that are expected to be issued in the run up to the January 2018 MiFID II compliance deadline.

Mark Davies, global head of RMS Data Services at Thomson Reuters, says the profiling service acts as an LEI health check. He explains: “When firms onboard clients they need to check the client has an LEI, but they don’t always look for all use cases of the LEI and whether it needs to be refreshed. In market testing of the LEI Profiling Service we’ve found we can help a lot of firms identify and close LEI gaps.”
