EU Securities Law

The Single Rulebook and ESMA

EU securities law is constructed upon the principle of a single rulebook—a harmonised set of directly applicable regulations and maximum-harmonisation directives that govern securities issuance, trading, market integrity, and infrastructure across all Member States. The European Securities and Markets Authority (ESMA) , headquartered in Paris, serves as the independent EU authority responsible for promoting supervisory convergence, directly supervising certain entities (including credit rating agencies and trade repositories), and developing binding technical standards (BTS) under the European Supervisory Authorities (ESA) framework. ESMA issues guidelines, recommendations, and Q&A to foster consistent application, and conducts peer reviews and breach of Union law investigations.

Prospectus Regulation 2017/1129

The Prospectus Regulation (EU) 2017/1129 harmonises the requirements for the drawing up, approval, and distribution of a prospectus when securities are offered to the public or admitted to trading on a regulated market. The regulation replaced the earlier Prospectus Directive (2003/71/EC, as amended), moving from a directive (requiring national transposition) to a directly applicable regulation. Key features include a single prospectus approved by the home Member State’s competent authority and valid throughout the EU (the European passport), tiered disclosure regimes (retail versus wholesale), and simplified disclosure for secondary issuances. The EU Growth Prospectus (Article 15) provides a reduced-disclosure regime for SMEs and issuers with limited market capitalisation.

Market Abuse Regulation 596/2014

The Market Abuse Regulation (MAR) 596/2014 establishes a unified framework for combating insider dealing, unlawful disclosure of inside information, and market manipulation. MAR applies directly in all Member States and replaces the earlier Market Abuse Directive (2003/6/EC). MAR prohibits insider dealing (Article 8), recommending or inducing another to engage in insider dealing (Article 8(2)), unlawful disclosure of inside information (Article 10), and market manipulation (Article 12). MAR requires issuers to disclose inside information as soon as possible (Article 17), maintain insider lists (Article 18), and report managers’ transactions (Article 19). Member States designate competent authorities (e.g., AMF in France, BaFin in Germany, CONSOB in Italy) with administrative sanctioning powers, including fines of at least €5 million for individuals and €15 million or 15% of annual turnover for legal persons.

MiFID II / MiFIR 2014/65

The Markets in Financial Instruments Directive II (MiFID II) 2014/65/EU and the accompanying Markets in Financial Instruments Regulation (MiFIR) 600/2014 form the cornerstone of EU investment services and trading regulation. MiFID II extended the scope of regulation to include structured deposits, organised trading facilities (OTFs), and algorithmic and high-frequency trading. Key provisions include investor protection rules (conduct of business, suitability and appropriateness assessments, independent advice and portfolio management), transparency requirements (pre-trade and post-trade transparency for equities, bonds, and derivatives), the trading obligation for shares (traded on a regulated market, MTF, or systematic internaliser), and position limits for commodity derivatives. MiFIR introduced mandatory trading on organised venues for certain derivatives (the trading obligation under Article 28).

CSDR 909/2014

The Central Securities Depositories Regulation (CSDR) 909/2014 harmonises securities settlement in the EU and governs central securities depositories (CSDs). CSDR imposes settlement discipline measures, including mandatory book-entry form for securities, settlement cycles (T+2 for most transactions), mandatory buy-ins for settlement fails, and passporting rights for CSDs. The regulation aims to increase safety and efficiency in the post-trade environment and reduce cross-border settlement costs within the Capital Markets Union.

Short Selling Regulation 236/2012

The Short Selling Regulation (SSR) 236/2012 creates a harmonised framework for short selling and credit default swaps (CDS) across the EU. It requires notification to competent authorities of net short positions that reach a threshold of 0.2% of issued share capital (public disclosure at 0.5%) and prohibits uncovered (naked) short selling of shares and sovereign CDS. The regulation grants ESMA emergency intervention powers (Article 28) to temporarily prohibit or restrict short selling in exceptional circumstances, as exercised during the COVID-19 market turmoil in March 2020.

EMIR 648/2012

The European Market Infrastructure Regulation (EMIR) 648/2012 governs over-the-counter (OTC) derivatives, central counterparties (CCPs), and trade repositories. EMIR imposes clearing obligations for standardised OTC derivatives through authorised CCPs, risk-mitigation techniques for non-centrally cleared derivatives (including margining and portfolio reconciliation), and reporting obligations to trade repositories. The EMIR Refit (2019) and EMIR 2.2 (2019) introduced proportionality for smaller counterparties, strengthened CCP supervision by ESMA, and established a framework for third-country CCP recognition.

Capital Markets Union (CMU)

The Capital Markets Union (CMU) is the European Commission’s flagship initiative to deepen and integrate EU capital markets, reduce reliance on bank financing, and enhance cross-border investment. Launched in 2015 and relaunched in 2020 (CMU 2.0 Action Plan), the CMU agenda includes initiatives to simplify prospectus requirements, foster venture capital (EuVECA and EuSEF), support covered bonds and green bonds, strengthen insolvency law convergence, and create a pan-European personal pension product (PEPP). The Listing Act (2024) further reduces administrative burdens for listed SMEs and growth companies.

ELTIF

The European Long-Term Investment Fund (ELTIF) Regulation (EU) 2015/760, amended in 2023 (ELTIF 2.0), establishes a pan-European framework for alternative investment funds that invest in long-term assets such as infrastructure, real estate, and SMEs. ELTIF 2.0 relaxed the minimum investment threshold (€10,000, with a cap of 10% of the investor’s portfolio) and expanded eligible asset classes to include real assets, forestry, and social infrastructure, aiming to channel retail and institutional capital into EU long-term projects.

ESAP

The European Single Access Point (ESAP) Regulation (EU) 2023/2859, enacted as part of the CMU action plan, establishes a centralised digital platform providing public access to financial and sustainability-related information about EU issuers. ESAP consolidates regulated information (prospectuses, annual and half-yearly reports, MAR disclosures, and sustainability reports under the Corporate Sustainability Reporting Directive) into a single searchable database, accessible from 2027. ESAP aims to increase transparency and comparability for investors across Member States.

Supervision and Enforcement

ESMA directly supervises credit rating agencies (CRAs) under the CRA Regulation (1060/2009), trade repositories under EMIR and SFTR, and securitisation repositories under the Securitisation Regulation (2017/2402). ESMA may also coordinate investigations, conduct stress tests of CCPs and CRAs, and impose fines on directly supervised entities. National competent authorities retain primary enforcement responsibility for MiFID II, MAR, and the Prospectus Regulation, with ESMA driving convergence through guidelines, peer reviews, and binding mediation.
