ESMA launches consultation on the evolution of European stock markets

The European Securities and Markets Authority (ESMA) has published a call for evidence with a data-driven analysis on the evolution of European stock markets between 2022 and 2025. The study, based on MiFIR transaction reporting data, reveals significant changes in trading dynamics that may require regulatory adjustments.

Quick Response

  • Available liquidity stable at 85% of total volume
  • On-book trading represents 75-80% of total volume
  • Decline in continuous lit trading compensated by growth in auctions and SI trading
  • ESMA seeks feedback on the concept of available liquidity
  • Consultation open until June 30, 2026

Overall stability with structural changes

ESMA's analysis highlights that European stock markets maintain good overall functionality. The share of available liquidity (addressable liquidity) remains stable at 85% of the total trading volume. Similarly, on-book trading (executed on regulated platforms) consistently represents 75-80% of the traded volume.

Changes in trading dynamics

A significant element emerging from the study is the decline in continuous lit trading (liquidity taking) between 2022 and 2025. This decline has been offset by an increase in activities in other trading mechanisms: closing auctions, frequent batch auctions, and trading from systematic internalisers (SI). These changes may reflect evolutions in market strategies and operator preferences.

Country-level analysis and available liquidity

The document delves into the distribution of liquidity among different trading mechanisms at the national level. ESMA seeks specific feedback on the concept of available liquidity and its treatment under the Technical Standards RTS 1, with particular attention to the post-trade transparency flagging framework. The consultation could lead to regulatory changes for more effective alignment with current market practices.

Regulatory implications and next steps

In addition to the consultation, ESMA informs stakeholders of the repeal of a Q&A that clarified the applicability of the tick-size regime to periodic auctions. The authority intends to continue monitoring market developments, taking into account recent changes to MiFIR, including the transition to a single volume cap and enhanced transparency obligations for systematic internalisers.

Deadlines and feedback

ESMA invites stakeholders to provide their opinions on the functioning of European stock markets by June 30, 2026. A feedback statement will be published in the second half of 2026. This consultative process represents a crucial opportunity for market operators and financial institutions to influence the future regulatory framework.

Impact on trading strategies

The observed changes in trading dynamics could have significant implications for operators' strategies. The growth of closing auctions and frequent batch auctions suggests a potential shift towards trading mechanisms that offer greater predictability and concentrated liquidity. Institutional investors and hedge funds may need to recalibrate their strategies to adapt to these changes.

Considerations for issuers

For listed companies, changes in trading dynamics could influence the liquidity and volatility of their securities. Issuers may want to closely monitor market evolution and consider strategies to improve the visibility and accessibility of their securities to investors. The ESMA consultation offers an opportunity to provide input on how regulations could be adapted to better support issuers' needs.

Prospects for European stock markets

Despite the observed changes, European stock markets continue to function well overall. The stability of available liquidity and the robustness of on-book trading provide a solid foundation for operators. However, the evolution towards alternative trading mechanisms requires careful observation and potential regulatory adjustment to ensure that markets remain efficient and transparent.

Market trends and emerging trends

The current context of European stock markets is characterized by a series of emerging trends that go beyond trading dynamics. One of the most relevant factors is the increasing institutional interest in sustainable financial instruments. According to recent data, ESG investments in European markets have recorded a 15% annual increase between 2022 and 2025, significantly influencing the composition of investors' portfolios.

Another crucial aspect is the impact of digitalization on financial markets. The adoption of blockchain technologies for post-trade and the growth of algorithmic trading platforms are transforming the way operators interact with markets. These technological changes may require further regulatory adjustments to ensure the security and transparency of transactions.

Implications for financial intermediaries

The changes in trading dynamics have significant implications for financial intermediaries, particularly for systematic internalisers (SI). With the increase in SI trading, these intermediaries may face challenges related to compliance with transparency regulations. ESMA has recently intensified controls on SIs, with particular attention to compliance with the enhanced transparency obligations introduced by MiFIR.

For intermediaries, it is crucial to adopt advanced technological solutions to monitor and manage operational risks. The use of artificial intelligence and machine learning for trading data analysis can provide a competitive advantage, allowing for the optimization of execution and regulatory compliance strategies.

Impact on the volatility and liquidity of securities

Changes in trading dynamics can influence the volatility and liquidity of listed securities. The increase in closing auctions and frequent batch auctions could reduce intraday volatility, offering investors a more stable environment for trading operations. However, this trend could also limit high-frequency trading opportunities, forcing operators to review their strategies.

For issuers, managing volatility becomes crucial to maintaining the attractiveness of their securities. Strategies such as the use of buyback programs and the implementation of transparent financial communications can help stabilize stock prices and attract institutional investors.

Future prospects and forecasts

Looking ahead, it is likely that European stock markets will continue to evolve in response to technological innovations and investor needs. The adoption of new technologies such as blockchain and artificial intelligence could further revolutionize trading dynamics, necessitating continuous regulatory adjustment.

ESMA and other regulatory authorities will need to closely monitor these developments to ensure that markets remain efficient, transparent, and resilient. The ongoing consultation represents an important step toward a more adaptable regulatory framework aligned with market needs.

Conclusions and recommendations

The ESMA analysis highlights the need for a proactive approach by all stakeholders in European stock markets. Operators, issuers, and financial intermediaries should closely monitor the evolution of trading dynamics and adapt their strategies accordingly. Participation in the ESMA consultation offers a valuable opportunity to contribute to a more effective regulatory framework aligned with market needs.

For institutional investors and hedge funds, diversifying trading strategies and adopting advanced technologies can offer a competitive advantage in a rapidly evolving market environment. For issuers, active management of volatility and transparent communication remain fundamental to maintaining investor confidence and ensuring the liquidity of their securities.

European stock markets continue to offer significant opportunities for operators but require constant attention to market dynamics and regulatory developments. With a strategic and proactive approach, stakeholders can successfully navigate the challenges and seize the opportunities offered by an ever-evolving market.
