My Lords, at this hour a letter is an attractive proposition. I counted some 27 questions, which is a pretty respectable ratio from the three distinguished speakers in this debate. I will try to deal with as many as I can in the time available. Clearly, I will have to read the Official Report with officials to see if there are any points we need to write on; I suspect there will be. Therefore, if we run out of time, I will include other answers in that communication.
The noble Baroness, Lady Bowles, asked why the amended thresholds which appear in Article 5(1)(a) and 5(1)(b) of the Commission of Delegated Regulation 2017/567—thresholds for determining which equity instruments are liquid—have not been changed. However, replacing references to Union data with UK market data in the legislation would change which instruments were classed as being liquid for UK market participants.
On the FCA not having the data, it needs sufficient time to build systems to analyse market data independently from ESMA. It estimates that this will take four years. As noted, the Treasury can end this period earlier if the transparency regime cannot operate earlier. The FCA does not have all the data relating to firms in the UK, as EU firms currently report back to their own competent authority and not to the FCA.
