The daily summary serves as a preliminary measure before the introduction of a fully-fledged consolidated tape for equities, which will provide a unified stream of trading information. Additionally, this Friday the FCA intends to define the parameters of the feed, which is likely to include both pre-trade and post-trade data. The inclusion of pre-trade data in the consolidated tape has sparked considerable discussion among London's financial community over recent months. There is widespread consensus on providing post-trade execution data, referred to as a "post-trade tape," but the argument over a "pre-trade tape" has revolved around the question of banks revealing pricing information.
The contention surrounding pre-trade data largely centers on banks' concerns that disclosing their pricing intentions could undermine their negotiating positions. Supporters of a comprehensive tape counter that greater transparency helps level the playing field for all investors.
A key component of the UK's post-Brexit strategy to strengthen its capital markets is the consolidated tape. By aggregating trade data from multiple venues, it aims to give investors a clearer picture of liquidity and pricing. However, exchanges like LSEG, which currently earn significant revenue from selling their own data, worry that a mandatory tape could erode their business model.

The debate also touches on market integrity, as high-frequency traders might exploit pre-trade data to the detriment of slower participants. The FCA's phased approach - starting with a daily summary - allows stakeholders to adjust gradually. This iterative process is typical for regulatory reforms of this magnitude, letting the authority gauge reactions and address technical hurdles before committing to a full tape.
The push for a consolidated tape is part of a broader effort to revive London's capital markets after Brexit, where fragmented data and higher costs have made the city less competitive against other global hubs. By providing a unified view of trading activity, regulators hope to attract more listings and restore confidence in UK equities.
The European equivalent is scheduled to launch in September.
Last month, London Stock Exchange Group PLC CEO Julia Hoggett published an opinion piece on the company's site, urging the FCA to proceed with caution and detailing the bourse's prerequisites for incorporating pre-trade data.
"If the FCA is not prepared to proceed with caution and protect market integrity, it may be essential to ask the Government to step in instead," Hoggett said in an opinion piece on the company's site.
Hoggett outlined four requirements for the plan, which include mandatory participation from all price-forming venues and operational resilience. She argued that the tape must also stop high-frequency traders from gaining an unfair advantage by acting on data before others, citing Michael Lewis's *Flash Boys*, and insisted on a revenue-sharing model to reward venues that produce price-forming data.
Shares of London Stock Exchange Group PLC jumped 6.44% on the news to 8,606.00 pence.
