People familiar with the matter said the UK Financial Conduct Authority will
start publishing daily aggregate UK equity trading data from Friday to boost
market transparency. The FCA will provide a one‑year historical backfill; the
daily updates are a transitional measure ahead of a full consolidated tape
(single source of UK equity trade data). The regulator will publish the data
stream’s coverage on Friday, which is expected to include pre‑ and post‑trade
data.
