The UK Financial Conduct Authority (FCA) has launched a strategic intervention to correct a significant under-reporting of market liquidity in London. This move follows a period of intense pressure where several high-profile companies shifted their primary listings to New York, citing the deeper capital pools of the United States. Market data suggests the "liquidity gap" is largely a reporting issue rather than a lack of activity. Between January and September 2025, the FCA estimated there were roughly 540 million transactions in UK shares. However, traditional public data feeds only captured 270 million of those trades. This means nearly 50% of the market’s true volume has been invisible to the public eye. To resolve this, the regulator is mandating the publication of all trading data, including activity from "dark pools"—private venues used by institutional investors to trade large blocks without immediate price impact. This transparency drive serves as an interim bridge toward a full "consolidated tape," a real-time data feed expected to launch in 2026 that will unify pricing from all UK trading venues. The broader UK market showed resilience at the start of 2026. The FTSE 100 hit the 10,000 mark for the first time in January, recently trading around 10,369. This performance has been supported by a recovery in the financial and mining sectors. The FTSE 250 has also seen gains, hovering near 23,129 as investor confidence stabilizes. Capital raising in London is seeing a significant rebound. In January 2025 alone, London saw £3.8 billion in equity capital raised, a 182% increase compared to the same period in the previous year. London currently ranks as the second-largest exchange globally for equity capital raised so far this year, trailing only the NASDAQ. The FCA’s goal is to prove that London remains a premier global hub. By exposing the "hidden" liquidity in dark pools and over-the-counter trades, the watchdog aims to lower the cost of capital for listed firms and reassure investors that the UK market is far more active and liquid than previously perceived.
