The Financial Conduct Authority will begin publishing a daily summary of trading in UK shares starting Friday [1, 2].

This move aims to increase market transparency and serves as a critical step toward the establishment of a single trading feed for the United Kingdom's equity markets [1, 2]. By providing a consistent snapshot of activity, the regulator seeks to reduce the fragmentation of data currently available to investors.

The initiative is part of a broader strategy to modernize the UK's financial infrastructure. The FCA said it would aim to launch a single feed of trading data for UK stock markets within 18 months [3]. This consolidated tape would provide a comprehensive view of all trades across different venues, rather than requiring participants to source data from multiple individual exchanges.

Currently, the lack of a centralized data feed can create disparities in how market participants perceive price and volume. The introduction of the daily equity snapshot is intended to bridge this gap by offering a free, consolidated overview of market activity [2].

The regulator is focusing on these changes to ensure the UK remains a competitive global financial hub. The transition to a consolidated tape is expected to lower costs for data users, and improve the overall efficiency of price discovery in the equity markets [1, 2].

The shift toward a consolidated tape represents a fundamental change in how UK market data is disseminated. By moving away from fragmented, venue-specific reporting and toward a centralized regulatory feed, the FCA is attempting to democratize access to high-quality trading data, potentially reducing the information advantage held by high-frequency traders and large institutional firms.
