European Union

EuroCTP is a joint venture established in 2023 by 14 bourses, which aims to provide a consolidated tape in financial trading within the EU. This forms part of the European Commission's Capital Markets Union.

United Kingdom

In July 2023, the UK's Financial Conduct Authority announced it was setting up a 'consolidated tape' system for City traders. As well as cutting costs and improving the quality of data, the FCA said the reforms would "increase transparency and access to trading data". The consolidated tape system is to be set up initially for the UK's bonds market followed by equities. A competitive tender process is to be opened up that would see a single firm providing the CT for bonds.
