Over the five years through 2024-25, revenue has rocketed at a compound annual rate of 14.5% to £2.3 billion. The Online Stock Brokerages industry has gained users quickly, as many investors left their brokers and started trading online. The online space offered a quick and easy way for less knowledgeable people to start investing and experienced traders to get real-time updates. Recovered incomes, volatile stock markets, an increasing number of mobile connections and a growing appetite for online stock trading have fuelled revenue growth. The online stock brokerage industry experienced a rapid upward shift in revenue during the 2020-21 market volatility caused by the pandemic, rewarding commission-free platforms like Trading212. The sector managed to capitalise on surging and declining phases. Innovations became critical, with brokerages like Trading212, FreeTrade and eToro introducing attractive features to win over customers, like replicating other trade moves. Despite the sector's vulnerability during the sharp sink of Bitcoin in 2022, its subsequent rebound in 2024-25 brought renewed prospects. Offering stocks and shares ISAs and SIPPs helped certain brokerages attract more tax-savvy customers. Simultaneously, intense price competition saw various platforms reduce their commissions to lure new users, leading to a climb in revenue of 7.7% in 2024-25. Over the five years through 2029-30, revenue is set to push up at a compound annual rate of 7.9% to £3.3 billion. Investor uncertainty will weaken as macro-headwinds subside and stock markets worldwide stabilise. The value of UK and US stock markets is forecast to strengthen, enticing traders to online platforms. As UK business profits recover due to stability, businesses can manage costs efficiently, leading to increased returns and more trade commissions for online stock brokers. The brokerage industry faces fierce price competition, with companies reducing commissions to attract and retain users alongside developing novel product offerings, like AI insights and advice, ISAs, extended trading hour products and tight cybersecurity. The average profit margin is expected to improve as industry entrants, including eToro (UK) Ltd, become profitable after years of significant losses resulting from investing heavily in R&D and marketing to attract users.

Stock and commodity exchanges can benefit from various sources of revenue, ranging from fees charged through the purchasing and selling of stocks and commodities to the listing of companies on exchanges with IPOs. Yet, this hasn't meant exchanges have been free of challenges, with many companies looking to more attractive overseas markets in countries like the US that embrace stronger growth. The most notable culprits have been ARM and CRH, refusing to put up with the increasingly cheaper valuations offered by UK stock exchanges. Stock and commodity exchange revenue is expected to boom at a compound annual rate of 11.5% over the five years through 2024-25 to £15.4 billion. Boosted by the London Stock Exchange Group's Refinitiv purchase in 2021-22, the growth numbers seem inflated. The industry saw ample consolidations, aided by MiFID II's initiation in 2018. However, M&As have now decreased because of high borrowing costs. New reporting demands have bumped up regulatory costs, resulting in thinner profits. Banks, aligning with Basel IV, are pulling back on investments. Post-COVID market turbulence fuelled trades, but it's slowing down with economic stabilisation. The inflation slowdown pushes investors towards higher-value securities, boosting trade value despite lower volumes. The weak pound has been beneficial for revenue, especially for the LSEG, bolstered by dollar-earning companies in the FTSE 100. Stock and commodity exchange industry revenue is expected to show a moderate increase of 1.3% in 2024-25. Revenue is forecast to climb at a compound annual rate of 4.1% over the five years through 2029-30 to £18.8 billion. The cautious descent of interest rates from the Bank of England will slow down volatility and ensure greater business confidence in the UK. This will bring back up consolidation activity to support revenue growth, reviving the digital information and exchange markets. The most pressing concern for the industry will be potential limitations on access to the EEA for the clearing segment of the industry, which could shatter short-term growth and keep the tap running for companies exiting UK exchanges.

While precise UK-specific data is unavailable within the provided information, extrapolating from the global market size of $693.77 million and a Compound Annual Growth Rate (CAGR) of 2.83%, a reasonable estimate for the UK market in 2025 can be derived considering its significant financial sector. Assuming the UK represents approximately 5% of the global e-brokerage market (a conservative estimate given its economic size and developed financial markets), the UK market size in 2025 could be estimated at around $34.7 million. This figure is likely influenced by factors such as increasing mobile penetration, growing retail investor participation, and the ongoing adoption of advanced trading platforms. The market is characterized by intense competition, with established players like IG Group and City Index vying for market share alongside newer entrants like eToro and Robinhood.

As of January 29, 2025, the FTSE index stood at 8,557.81 points - well above its average value of around 7,500 points in the past few years.On the 12th of March 2020, amid the escalating crisis surrounding the coronavirus and fears of a global recession, the FTSE 100 suffered the second largest one day crash in its history and the biggest since the 1987 market crash. On the 23rd of March, the FTSE index saw its lowest value this year to date at 4,993.89 but has since began a tentative recovery. With the continuation of the pandemic, the FTSE 100 index was making a tentative recovery between late March 2020 and early June 2020. Since then the FSTE 100 index had plateaued towards the end of July, before starting a tentative upward trend in November. FTSE 100 The Financial Times Stock Exchange 100 Index, otherwise known as the FTSE 100 Index is a share index of the 100 largest companies trading on the London Stock Exchange in terms of market capitalization.

We investigate the effects of fragmentation in equity markets on the quality of trading outcomes in a panel of FTSE stocks over the period 2008-2011. This period coincided with a great deal of turbulence in the UK equity markets, which had multiple causes that need to be controlled for. To achieve this, we use the common correlated effects estimator for large heterogeneous panels. We extend this estimator to quantile regression to analyse the whole conditional distribution of market quality. We find that both fragmentation in visible order books and dark trading that is offered outside the visible order book lower volatility. But dark trading increases the variability of volatility, while visible fragmentation has the opposite effect, in particular at the upper quantiles of the conditional distribution. The transition from a monopolistic to a fragmented market is non-monotonic with respect to the degree of fragmentation.

Volatility in financial markets has been high in recent years, which has, at times, benefitted the brokerage industry through greater trading activity as investors look to capitalise on price swings. Most notably, the COVID-19 pandemic, the Ukraine conflict and aggressive interest hikes from Central Banks facing rampant inflation have incited severe volatility. Revenue is expected to grow at a compound annual rate of 2.7% over the five years through 2023-24 to £38.1 billion, including estimated growth of 3.9% in 2023-24. Although volatility can benefit the industry, it can also deter investors, incentivising them to delay investments until economic uncertainty subsides. In recent years, uncertainty has mainly stemmed from the aggressive interest rate hikes and their expected trajectory, hitting stock and bond markets in 2022 and hurting trading activity. Although interest rate uncertainty persisted going into 2023-24, stock markets improved thanks to exceptional growth from large-cap tech stocks and a sharp rally at the end of the year as investors bet on the end of rate hikes. Competition has softened as considerable consolidation activity has occurred between SMEs in the brokerage industry. However, the Markets in Financial Instruments Directive II has ramped up operating costs for brokerage firms, hurting profitability. Continued investment in software to help automate compliance procedures have benefitted margins, although the brokerage industry remains labour-intensive. Revenue is forecast to grow at a compound annual rate of 3.5% over the five years through 2028-29 to £45.2 billion, while the average industry profit margin is expected to reach 24.8%. The market narrative for interest rates is higher for longer, weighing on stock markets and hitting demand for brokers as trading activity slows. However, rate cuts are expected to occur in the second half of 2024-25, supporting bond values and stocks driving revenue growth in the short term. Further regulations related to Basel III are set to come into force in January 2025, adding pressure to brokers' operating costs. Due to Brexit, large international brokers are also shifting employees to overseas domiciles, adding downward pressure to revenue growth.
