The Financial Conduct Authority has devoted the September 2017 issue of its Market Watch newsletter to a discussion of aspects of FCA reporting functionality and the means by which firms can meet their reporting obligations under MiFID II from January 3, 2018. Market Watch issue 53 provides details of: (i) the requirement for firms subject to MiFID II transaction reporting obligations (and their eligible clients) to have a Legal Entity Identifier and what firms need to do to obtain one; (ii) how firms can apply to become a submitting entity to make submissions of market data via the FCA's Market Data Processor; (iii) the requirements external users will need to meet to be able to request extracts of transaction reports from the FCA via the MDP entity portal, which goes live on January 3, 2018; (iv) the ways in which operators of trading venues and investment firms can fulfill their market data reporting obligations by using outsourcing arrangements with third parties; and (v) clarification that Systematic Internalisers must submit instrument reference data to the FCA for financial instruments where the underlying instrument is a financial instrument traded on a trading venue, or an index or a basket composed of financial instruments traded on a trading venue.
