Published in Reference Data

The FCA Financial Instruments Reference Data System (FCA FIRDS) was built to replace the European Securities and Markets Authority (ESMA) FIRDS in the UK as part of the FCA’s planning for Brexit. The intended audience is the UK and EU market participants which need to make use of the instrument reference data for the purpose of complying with the Markets in Financial Instruments (Amendment) (EU Exit) Regulations 2018 (UK MiFI Regs) and the associated Binding Technical Standards.

The FCA FIRDS files are a consolidation of instrument reference data collected from:

  • UK trading venues,
  • UK systematic internalisers (SIs), and
  • the ESMA FIRDS files containing the EU27 instrument reference data

Key Features and Coverage on RIMES

For this data source, RIMES hosts approximately 40 companies and instrument reference data. FCA FIRDS makes instrument reference data available in the form of machine-readable files:

  • Full file: the full file contains the full instrument reference data received by the FCA before the applicable cut-off time (21:00 CET1) and is consolidated with the ESMA EU27 instrument reference data, for all instruments that are still active.
  • Delta file: the delta file contains all records of instrument reference data for which a change has occurred (addition, modification, deletion) since the generation of the last set of files.

Some of the data items available for this source include the following:

  • COMPANY items: Administrator Country, Database Source and Symbol Code, FCA Administrator, Index Symbol (Source), ISIN Code, RIMES Calculated ISIN, etc.
