Single market meaning

Published by a LexisNexis EU Law expert
What does Single market mean?
Single market describes, in practice, a legal area where goods, services, persons and capital move without internal customs or unjustified regulatory barriers, achieved through harmonisation and mutual recognition and underpinned by competition and state aid/subsidy control. In EU law, the EU Single Market is anchored in the Treaty on the Functioning of the European Union, secondary legislation and Court of Justice case law; it removes internal borders and restricts national rules that hinder cross-border trade, establishment or mobility. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, but the legal position differs post‑Brexit. Great Britain is outside the EU Single Market; access now depends on compliance with EU requirements and the EU–UK Trade and Cooperation Agreement, with customs and regulatory checks. Northern Ireland aligns with significant EU goods rules under the Windsor Framework, giving continued access to the EU goods single market for qualifying goods while remaining in the UK customs territory. Ireland remains within the EU Single Market. The term is also used for the EEA single market (EU plus certain EFTA states). Distinguish the EU Single Market from the UK Internal Market created by the UK Internal Market Act 2020.

Archived UCITS timeline: EU and UK legislative and regulatory milestones 2009–2026 (PRIIPs KIDs/KIIDs, AIFMD II, cross-border distribution, sustainability, DORA, ESAP, FCA/HMT updates)

ARCHIVED: This Practice Note is archived and is no longer maintained. UCITS is the acronym for undertakings for collective investment in transferable securities. The expression derives from Directive (EC) 85/611 concerning the coordination of laws, regulations and administrative provisions relating to undertakings for collective investment in transferable securities (the Original UCITS Directive), which was adopted in 1985. The purpose of the Original UCITS Directive was to establish a single market for open-ended retail investment funds that offered enhanced protection for investors. The UCITS framework has been updated on several occasions, with the Management Company Directive 2001/107/EU adopted in 2002 and the Product Directive 2001/108/EU implemented in 2005 (together referred to as UCITS III); followed by implementation in 2011 of Directive 2009/65/EC (the UCITS Directive, also called UCITS IV), which repealed and replaced the Original UCITS Directive; and Directive 2014/91/EU (UCITS V), which was transposed into national law on 18 March 2016...

Allotting Shares and Disapplying Pre-emption: Checklist for UK Listed Companies - CA 2006 Authorisations, Investor Guidelines, Listing Rules/DTRs, Filings and Market Disclosures (pre-29 July 2024 regime)

STOP PRESS: A major overhaul of the UK listing framework took effect on 29 July 2024, removing the premium and standard segments and introducing a single listing category for equity shares in commercial companies. The commercial companies category is strongly disclosure-led, with an emphasis on transparency, and sits alongside other listing categories, such as shell companies, secondary listing and closed-ended investment fund categories. A new UK Listing Rules sourcebook came into force to deliver and implement the reforms, and the previous Listing Rules sourcebook was revoked in full. For further details, see Practice Note: Reform of the UK listing regime—fundamentals. This Checklist reflects the regime as it stood before 29 July 2024. The allotment and issue of shares are governed by statutory rules, which vary according to the type of company proposing the allotment (private or public, listed or unlisted) and whether that company has a single class or multiple classes of shares. This checklist sets out the procedure for a listed company to allot shares and to...

Smurfit Kappa/WestRock EU merger control: German folding-carton overlaps, EEA versus national market definition, and beverage-carton segmentation

The European Commission’s determination on whether buyers depend on domestic packaging suppliers, or whether the arena is EEA‑wide, will dictate if the merger triggers competition issues for regulators evaluating cross‑border supply dynamics. In earlier probes, the watchdog has increasingly suggested the market is heading clearly towards the latter as the prevailing direction of travel in recent years. Folding cartons are a form of cardboard pack used for everything from beer bottles and frozen pizzas to tobacco and medicines across consumer sectors. How straightforward the parties’ route to clearance proves could also rest on whether officials see a single cartons market, or one divided by end use and application. Ireland’s paper packaging group Smurfit Kappa and US competitor WestRock agreed last September to combine in an US$11bn transaction they say will forge a “global leader in sustainable packaging.” They have not yet filed with the Commission, but have indicated they expect to close in the second quarter of this year. When unveiling the tie‑up last year, the firms called it “geographically...

Euro interest rate derivatives cartel: EU General Court upholds HSBC Article 101 infringement but annuls fine for insufficient reasons in calculation; clarifies scope of single and continuous infringement

See further: timeline and relevant/related cases. Case facts Outline: Appeal brought before the General Court challenging the Commission’s decision of 7 December 2016, which found infringements and levied fines on three banks that did not settle, due to their involvement in a cartel in the Euro interest rate derivatives (EIRD) market (Case AT.39914). Latest developments On 24 September 2019, the General Court delivered its judgment, largely confirming the Commission’s conclusion that HSBC Holdings plc took part in a single and continuous infringement of Article 101(1) TFEU. Nonetheless, the General Court set aside the fine imposed on HSBC Holdings plc because the Commission provided ‘insufficient reasons’ for the methodology used to calculate that penalty...

STOP PRESS: A major overhaul of the UK listings regime took effect on 29 July 2024, scrapping both the premium and the standard listing segments and replacing them with a single category for equity shares in commercial companies.

STOP PRESS: The UK’s prospectus regime, previously derived from the EU Prospectus Regulation, has been superseded by the Public Offers and Admission to Trading Regulations 2024 (POATRs), with all detailed admission to trading requirements now contained in the Financial Conduct Authority (FCA) admission rules.

Can a pre-31 Dec 2020 passported FCA-approved prospectus be used for EU public offers after 31 Dec 2020?

Passporting provisions in the Prospectus Regulation Under the Prospectus Regulation, an issuer must publish a prospectus and have it approved by a competent authority when offering securities to the public in the EEA or when applying for admission of securities to a regulated market, where no relevant exemption applies. To streamline cross-border share offerings within the EEA, the EU prospectus regime provides passporting arrangements that permit companies to produce a single prospectus usable throughout the EEA, avoiding the preparation of multiple documents for separate jurisdictions. Articles 24 to 26 of the Prospectus Regulation (EU) 2017/1129 set out these passporting provisions, stating that a prospectus approved by the competent authority in one EEA state (the home member state) can be relied upon in another EEA state (the host member state) without requiring the prospectus to be approved again by the competent authority in the host member state. As a result, a UK issuer has been able to undertake a cross-border share offer across the EEA on the basis of...

It proceeds on the basis that the company concerned is a private company limited by shares proposing to buy back shares off-market and that the contemplated buyback is neither for the purposes of, nor pursuant to, an employees’ share scheme within the meaning of section 1166 of the Companies Act 2006 (CA 2006)...
