LONDON, Feb 9 (Reuters) - Britain's financial regulator wants to publish all trading data for London-listed shares in a bid to tackle the under-reporting of market liquidity that has driven some companies to shift their listing to the United States, the watchdog said on Monday.
The Financial Conduct Authority's interim director of markets, Simon Walls, told the Financial Times in a story published earlier on Monday that the regulator planned to collect and publish all share-trading data from every venue, including exchanges and dark pools.
Dark pools are private exchanges for trading securities often popular with institutional investors who want to execute large transactions without unduly affecting prices.
A spokesperson for the FCA confirmed the plans to Reuters.
"The truth is we have way more liquidity here than is often reported and that is just silly," Walls told the FT. "We are talking to loads of parties at the moment about whether the FCA can, at a little bit of risk to ourselves, step in and just sort this out."
The FCA's plans are a stopgap, the FT reported, before the regulator launches its "consolidated tape" for equities, likely next year. This tape will combine real-time data from different equity trading platforms into a single feed.
The proposals are part of a wider effort by the FCA to boost the appeal of the London Stock Exchange, which is battling a downturn in the number of new stock market listings and the shift of some existing companies to other exchanges, typically in the United States, where executives think they can get a better valuation.
In January, Britain's revamped framework for raising capital came into force, aiming to make it easier and cheaper for listed and private companies to attract funding.
The FCA believes most UK market share liquidity data is under-reported because it is only based on the London Stock Exchange's central limit order book and excludes many trades, including periodic orders at the LSE, the FT reported.

Market liquidity refers to the ease with which an asset can be bought or sold in the market without affecting its price. High liquidity means assets can be quickly sold, while low liquidity can lead to price fluctuations.
The Financial Conduct Authority (FCA) is a regulatory body in the UK responsible for overseeing financial markets and protecting consumers. It aims to ensure that financial markets operate fairly and transparently.
Trading data includes information about the buying and selling of financial assets, such as stocks and bonds. It typically encompasses prices, volumes, and transaction times, helping investors make informed decisions.
A trading platform is software that allows investors to buy and sell financial assets online. It provides tools for market analysis, order execution, and portfolio management.
