FCA Breaks from EU in Operating Data Repository that Underpins Key Regulation

5 January 2021

On the 31 December 2020, the European Securities & Markets authority (ESMA) switched off the FCA’s access to its MIFID systems. In concert, the FCA launched a discrete and separate system on 1 January 2021.

This Brexit-related transition is significant. Since the launch of MiFID II, the ESMA database called FIRDS (Financial Instruments Reference Data System) has been dubbed the “golden source of reference data” for transaction reporting under MiFID. The database plays a key role in the timely production of daily transaction reports produced by market participants across the UK and EU. To this end, the ESMA FIRDS reference data have to be accurate, complete, reliable and up-to-date as the production of daily reports are produced under strict time constraints. Any inaccuracies in the reference data have widespread downstream affects.

Since the FCA now operates its own FIRDS database, there are two “golden sources” of reference data for which there is a heavy reliance. This places the FCA squarely in the spotlight as the integrity of data in the FCA FIRDS database is now instrumental in the regulatory obligations it had a hand in setting forward.

Michelle Zak, co-founder of Qomply, a leading regulatory technology firm, notes: “The sheer volume of firms and reports being processed means that any disruptions or inconsistent data could negatively affect firms and their reporting ability. The FCA is using its own database for the first time and, with roughly 7 billion transactions at stake, any small disruption could have a major impact. “

According to a recent Freedom of Information Request from Qomply, the FCA disclosed that they processed approximately 7 billion transactions in 2018, 5.6 billion transactions in 2019 and 6.5 billion transactions for YTD 2020 up to mid-November. These reports all relate to the reference data held in the ESMA FIRDS. New reports for UK transactions processed in 2021 are now dependent upon the FCA FIRDS.

The FCA has further disclosed that they have processed transaction reports from over 3,000 unique “executing entities” or, simply put, investment firms and trading venues. At the start of MiFID in 2018, approximately 3,100 individual firms submitted transaction reports, in 2019 this figure rose to 3,600, and as of mid-November 2020, the FCA has processed reports from nearly 3,300 firms. This figure includes not only firms falling under the MiFID regime but also third country entities that have traded on a UK trading venue for which the venue reported on behalf of the firm.

Therefore, any potential issues could affect a significant pool of the 3,000 firms reporting through the FCA.

Currently, Qomply estimates that ESMA is storing 68 million records of reference data and the new FCA database is storing roughly 22 million records as of early January 2021. In the past, ESMA was heavily criticised for the accuracy of the data stored in its centralised FIRDS database therefore the upcoming months will determine FCA’s success in doing the same. (see Germany’s Ministry of Finance’s position paper on MiFID and MiFIR data accuracy)

The ESMA FIRDS database was intended to be the definitive reference for all financial instruments included in the scope of MiFID II. If an instrument or its underlying instrument is found in FIRDS for the trading date, then the instrument is deemed reportable. With Brexit, part of this responsibility of maintaining accurate data is with the FCA.

To facilitate the transparency of data and allow firms to conduct quick reportability checks, Qomply, has released a free service that determines if a financial instrument is MiFID-reportable in the UK, the EU, or both.

Zak comments “Qomply has offered a free service allowing firms to input an ISIN (instrument identifier), a string of ISINs, or upload a CSV file for a specific trade date. The service will report, as of that trade date, the region and reportability of that instrument. Therefore, firms will know, unequivocally, if the instrument was reportable, when, and where.“

This is the only service freely available that queries both EU and UK databases and conducts searches across multiple instruments at once. Qomply anticipates its service will remove the ambiguity of reporting obligations and allow firms to reach back in time to determine if an instrument was reportable in a specific region.

Zak notes “Understandably, any big changes have the potential to be disruptive, at least we can make it somewhat easier for firms to get answers on their reporting obligations in one place as opposed to issuing multiple queries across different locations”.

Article 26 of MiFIR created an obligation of Transaction Reporting that went into effect on January 3rd 2018. The legislature focuses on investment products that are traded on a traded venue (TOTV) or a derivative based on a product that is TOTV (also called UTOTV, underlying traded on a traded venue).

This key regulatory requirement, under the MiFID regime, plays a pivotal part in regulators detecting market abuse.

1. The number of unique Legal Entity Identifier (LEIs) representing the EXECUTING ENTITY for a transaction report (RTS22) submitted to the FCA, broken down by year 2018, 2019, and YTD 2020 (17 November 2020).

The number of unique LEIs identified as the “executing entity” in a transaction report received by the FCA is presented by submission date and year below. This data includes instances where a transaction report is submitted to the FCA by a UK trading venue under Article 26(5) of MiFIR on behalf of an executing entity that is not subject to transaction reporting obligations. It does not include transaction reports received by the FCA through ESMA’s Transaction Reporting Exchange Mechanism (TREM).
