Strengthening Transparency and Access to Market Data

Our work to improve transparency and access to trade data in UK equity markets.

Friday 31 July 2026 marked an important milestone in our work to strengthen UK equity markets, with the publication of three closely linked initiatives aimed at improving transparency, strengthening access to market-wide information and supporting confidence in UK equity markets among issuers and investors: 

  • A policy statement on the framework for the UK Equity Consolidated Tape (CT) and the next steps for delivery (CP26/31).
  • The launch of the market activity reporter for shares (available here).
  • A consultation paper on supporting equity market transparency and considering market structure developments (CP26/30). 

Equity consolidated tape

UK equity markets offer investors a wide choice of trading options, through competition and innovation. However, greater choice has also increased fragmentation. Obtaining a complete picture of trading activity can be complex and expensive, meaning market-wide data is often under-used. It also means the depth and liquidity of UK equity markets are often under-appreciated. 

CP26/31 sets out the key design features of the future equity consolidated tape, which will bring together trading information from across the market into a single source. It will include both post-trade data and the pre-trade best bid and offer (i.e., top of book). Top of book data will be attributed, meaning that the CT will display which venues have offered separate prices.

We expect that introducing an equity CT will ensure that access to consolidated UK equity data is straightforward and affordable. We think this will strengthen UK market functioning. Notably, it will help demonstrate to portfolio managers the market wide liquidity in UK equities, helping them to confidently develop and deploy suitable trading and investment strategies. 

This publication puts us on a path to deliver an equity CT within 18 months, making market-wide data easier to access and use for issuers and investors. 

Further, in CP26/31, we are consulting on the inclusion of quotes from systematic internalisers (i.e. quotes that investment firms make available to clients over-the-counter) in the CT (by 16 October) and seeking views on key contractual requirements for the CT provider (by 18 September). 

Market activity reporter for shares

Until the CT becomes operational, The Market Activity Reporter for Shares provides an interim source of market-level trading information. It publishes the following information on an end-of-day basis: 

  • the total trading activity in UK-listed shares traded on UK trading venues and over-the-counter and reported in the UK, and 
  • for the same market-level metrics, total trading activity adjusted to remove technical trades that are not part of the price-forming process.

We believe that this data can support investors and issuers to better understand the depth and liquidity of UK equity markets across the full range of execution mechanisms.

Consultation on supporting equity market transparency and considering market structure developments

We have published a consultation (CP26/30) on targeted changes to the UK equity markets framework. The proposals reflect the increasingly diverse nature of UK equity markets, where liquidity is accessed through a range of execution mechanisms, including central limit order books, auctions, systematic internalisers and other bilateral trading arrangements.

The package is intended to improve access to information, support effective price formation and resilient markets, and enhance the quality and usability of transparency data, including for the future equity consolidated tape. The FCA’s assessment is that UK equity markets are functioning effectively, but that ongoing market evolution means it is important to ensure the framework remains clear, proportionate and capable of supporting market quality.

The consultation includes proposals on post-trade transparency for certain non-price-forming transactions, supervisory expectations for back-reporting, changes to the reference price waiver, simplification of systematic internaliser quoting obligations, guidance on market outages, and the FCA’s approach to monitoring broader market structure developments.

We are seeking views on the proposals, including the indicators the FCA should monitor and the tools that could be available if proportionate intervention is needed in future. The consultation is open until 16 October.

 

 

 

Language in Regulatory Announcements

We have recently identified a growing trend of potentially misleading statements by issuers in regulatory announcements that contain language which is vague, exaggerated and flamboyant. In some cases, announcements appear to contain or resemble marketing material rather than regulated information. In some of our recent enquiries, our concerns have grown because: 

  1. Issuers have released regulatory announcements more frequently than appears justified by their content. 
  2. Announcements are marked as containing inside information when they almost certainly do not, and/or
  3. The announcements are released against a backdrop of very significant spikes in the issuers’ share price. 

Examples of issuers’ statements in regulatory announcements that have raised concerns include: 

  • An issuer providing unnecessary minor updates regarding the progress of commercial agreements and ventures which have previously been announced. 
  • An issuer providing repeated and detailed updates on possibly favourable macroeconomic and political conditions, which are already in the public domain. 
  • Issuers using broad, publicly available, sector-wide commentary to provide support for their projects, without enough detail to inform investors of the direct material implications of these developments for the issuers’ projects. 
  • An issuer claiming support for their project from a public figure when (as the issuer explained in response to our enquiry) this claim was solely based on a passing and immaterial comment made during a meeting. 
  • Issuers using sensationalist language in regulatory announcements, of the type normally reserved for promotional activity.   

Regulatory announcements of this kind risk misleading investors.

Relevant Rules  

Our expectations for regulatory announcements are based on requirements in Market Abuse Regulation (UK MAR), the Disclosure Guidance and Transparency Rules (DTR) and the UK Listing Rules (UKLR).  

DTR 6.3.3R requires issuers to use a RIS (Regulatory Information Service) to disclose regulated information. The FCA Handbook defines 'regulated information' – as all information which an issuer is required to disclose under the DTRs, or articles 17 to 19 of UK MAR, or the UKLRs. This does not include marketing material. It includes, but is not limited to: 

  • Periodic financial reporting (DTR 4) 
  • Various Information requirements for issuers of shares and debt securities (DTR 6.1R) 
  • Notification of board changes and directors’ details (UKLR 6.4.6R) 
  • Public disclosure of inside information (UK MAR Article 17) 
  • Managers’ transactions (UK MAR Article 19.3) 

We consider that the obligation on listed issuers to have adequate systems and controls (UKLR 2.2.1R, Listing Principle 1) covers the creation and dissemination of compliant regulatory announcements. Issuers are subject to UKLR1.3.3R (and the identical DTR 1A.3.2R), which require issuers to take reasonable care to ensure their regulatory disclosures are accurate and full. UKLR 2.2.1R Listing Principle 6, which concerns false markets, imposes a similar obligation. These rules supplement UK MAR Article 12(1)(c) which defines market manipulation as including the dissemination of false or misleading information.

We have previously provided our expectations for issuers in the context of UK MAR 12.1(c) in PMB 52, specifically, that 'management should be careful to ensure the language used in communications is clear and unambiguous so that it is understood by investors'. 

The rules cited above provide a clear framework for issuers. We accept that regulatory announcements cannot always be limited purely to regulated information, and that appropriate context and relevant analysis, concisely expressed, may be necessary to help investors’ understand. 

But issuers must take care when drafting and releasing regulatory announcements. Where their content strays too far from regulated information, we will consider whether or not their content has become misleading for the purpose of the UKLRs or, in the most serious cases, UK MAR and whether this also indicates poor systems and controls at the issuer. 

UK MAR Article 17.1 mandates disclosure of inside information (which is a type of regulated information) as soon as possible and reminds issuers that they 'shall not combine the disclosure of inside information to the public with the marketing of [their] activities'. 

This rule creates a clear dividing line between inside information and marketing material. Issuers should also be mindful of the FCA’s financial promotion rules and guidance. PERG 8.21.1G notes that, whilst 'statements of fact alone will not be inducements', and while it is rare for company statements or briefings to involve an invitation, there may be circumstances where there is a promotional element that may amount to an inducement to engage in investment activity. PERG 8.21 provides detailed guidance on this issue.

This is recognised in practice by some RIS providers who have alternative services for the dissemination of marketing material. 

If issuers wish to release marketing material, they may do so through non-regulatory newswire services. They may also of course, use their own website, social media channels or other appropriate communications outlets such as media newswire services for marketing purposes - noting of course, that UK MAR can apply to any type of misleading statement, however it is disseminated.  

Where issuers choose to release information through a formal regulatory announcement, we reiterate the basic requirement under UKLR 1.3.3R. Issuers must take reasonable care when preparing regulatory announcements. Where announcements fall short of the required standard, we will consider taking action. 

 

 

 

Review of sponsor specialist due diligence for ESCC admissions

We reviewed how sponsors use expert reports to support specialist due diligence for new admissions to the Equity Shares (Commercial Companies) (ESCC) category.

A sponsor may seek to rely on a third-party specialist where deeper technical expertise and/or independent reporting is required. In these cases, the sponsor will typically obtain a report that provides it with a reasonable basis for its own opinion.  

We wanted to understand if and how market practice has evolved since the July 2024 Listings reforms, and to share our anonymised observations, particularly examples of good practice, with all sponsors. We focused on transactions carried out since July 2024.  

Our review, led by our Primary Market Specialist Supervision (PMSS) team, suggests that market practice around specialist due diligence is changing, particularly in the use of long form financial due diligence (‘long form’) reports. 

We were encouraged to see sponsors exercising judgements around expert reports. We were also particularly interested to hear one sponsor noting that a proportionate approach to expert reporting was a factor that influenced an overseas issuer’s decision to list in the UK.

Background

To reduce unnecessary friction and cost, we previously encouraged, in Primary Market Technical Note 722, sponsors to carefully judge the use of expert reporting as part of forming a reasonable opinion after due and careful enquiry. We had reminded sponsors that they need not presume that specialist reporting would be required in all cases. Also, that sponsors should take an active role in determining the nature and extent of expert reporting specific to the transaction in question, and avoid simply relying on ‘off the shelf’ assurance products where these may not be wholly appropriate.  

Our previous encouragement for sponsors in Primary Market Technical Note 722, to consider carefully whether expert reporting is required, was not intended to reduce or remove the commissioning of reports where the sponsor judges them to be necessary. On the contrary, we explicitly recognised that there may be limits to a sponsor’s competence and capacity to perform specialised due diligence, where expert reporting is vital. We were pleased to find that where the full suite of reports was commissioned, most sponsors were able to clearly explain why this work was necessary, how it addressed transaction-specific risks and contributed to overall sponsor comfort.

What we did

We contacted a sample of sponsor firms to obtain information about their approach to expert reporting on selected new admissions to the ESCC category since July 2024. The sample included both smaller and larger sponsors, covering both moves from the Alternative Investment Market (AIM) to the Main Market and ESCC Initial Public Offerings (IPOs). We primarily considered financial-focused expert reporting, such as long form reports, working capital and Financial Position and Prospects Procedures (FPPP) reports. We reviewed the information, then carried out onsite visits where we discussed in more detail those transactions and approaches taken to expert reporting.  

What we found

Conlclusion

Since the July 2024 reforms, some sponsors have been moving away from a uniform, ‘off the shelf’ approach to expert reporting, and are instead adopting more tailored and proportionate approaches. 

This evolution has been most evident in long form reporting, but we have also seen greater flexibility emerging in relation to working capital and FPPP reports. 

We are encouraged to see sponsors exercising judgement when deciding whether, and in what form, expert reports should be commissioned. Where we saw alternative approaches, the sponsor was able to articulate clearly why these were appropriate for a specific transaction, how alternative procedures provided adequate comfort, where additional reporting was needed, and how their approach supported the sponsor’s overall responsibilities. Sponsors were also clearly recording the judgement displayed.  

Finally, we were particularly interested to hear one sponsor noting that the renewed focus on proportionate approaches to expert reporting around new admissions was a factor that influenced an overseas issuer’s decision to list in the UK. It’s positive to hear that evolving sponsor practices may be making UK markets more attractive, while still maintaining appropriate standards of diligence and investor protection.

 

 

 

Delayed disclosure of inside information

Review of delayed disclosure of inside information (DDII) notifications under Article 17(4) of UK MAR

As part of our ongoing work on delayed disclosure under Article 17(4) of the UK Market Abuse Regulation (UK MAR), we continued to review DDII notifications submitted to us and followed up where notifications appeared to be outliers.  This supports our strategic objectives of supporting market integrity, orderly investments and investor confidence.

This builds on our thematic work from November 2020 and PMB 59, where we said would  monitor notifications that seemed unusual for certain reasons and engage with issuers where necessary.

Here, we set out some key observations and themes identified in our recent work. Overall, we did not identify widespread failings in the use of the delay mechanism, although we observed some inconsistent practices in the identification and handling of inside information.

Article 17(4) of UK MAR, allows an issuer to delay disclosure of inside information to the public only if all the following conditions are met:  

(a) immediate disclosure is likely to prejudice the legitimate interests of the issuer
(b) delay of disclosure is not likely to mislead the public    
(c) the issuer is able to ensure the confidentiality of the information  

We note that the EU is beginning to implement changes to EU MAR, including related technical standards and guidelines. UK issuers, subject to UK MAR, should continue to comply with related technical standards and applicable guidance. 

Where relevant, firms and market participants should continue to apply ESMA guidelines and recommendations that existed before the end of the transition period, interpreted in the context of the UK’s withdrawal from the EU and related legislative changes. 

Overview of Our Work

Since our last thematic review, we have continued to review DDII notifications showing an unusually long period of delayed disclosure or where the circumstances around the delay are not immediately clear from the notification provided. We send requests for information to certain issuers which file such notifications to gain an understanding as to the circumstances of the delay.

Our objective is to understand whether issuers appropriately rely on the delayed disclosure regime under Article 17(4) of UK MAR, and whether the duration of any delay, or other unusual circumstances, indicate any broader concerns about how issuers identify and handle inside information.

We also engage with a small number of larger Main Market issuers that have not submitted DDII notifications over an extended period, to understand why this is the case. 

Key observations and themes

Overall, we are pleased to note that our enquiries have not identified widespread or systemic failures in the application of the delay mechanism in Article 17(4) of UK MAR.

Where issuers relied on the delay, we are generally satisfied that they understood the three conditions for delay, and, for the most part, had appropriate processes in place to support confidentiality. They also had ongoing assessment of whether all conditions for the delay continued to be met during the period.

Where extended or unusual delays arose, they were mainly caused by: (1) incorrect classification of inside information and (2) issues arising from ongoing assessments of the inside information, or sometimes a lack of such assessment.   
Our enquiries revealed some practices in the handling of inside information by issuers that could be improved.  

Below we explore some key themes that arose from the workstream:  

FCA emergency powers under the Short Selling Regulations 2025 

Overview

The Short Selling Regulations 2025 (SSR 2025) together with the Short Selling Rules Sourcebook 2026 introduce a revised UK framework for short selling. The Statement of Policy sets out the FCA’s approach to the use of its emergency intervention powers provided in the SSR 2025. These powers are designed to support the orderly functioning of markets while recognising the role of short selling in price formation, liquidity, and risk management. Our short selling rules came into force on Monday 13 July 2026. Read more here.   

Under SSR 2025, the FCA has revised emergency intervention powers for short selling. We will use these powers only in exceptional circumstances and where intervention is proportionate to the risks identified. 

Regulatory Powers

The SSR 2025 provides us with emergency intervention tools:  

  • Regulation 13 – Power to require notification  
  • Regulation 15 – Power to prohibit or impose conditions on short selling  
  • Regulation 17 – Power to restrict short selling following a significant price fall  

We have emphasised that we will apply a high bar for intervention, with powers used only in exceptional circumstances or where necessary to address disorderly market conditions.  

Regulation 13 – Power to require notification  

Regulation 13 enables us to increase our visibility of short selling activity where market conditions require closer monitoring. 
In particular, we may:  

  • Require notification of net short positions at lower thresholds than the standard 0.2% level.   
  • Require reporting of positions in other financial instruments, including transactions conferring a financial advantage from price declines. 
  • Request additional information on short selling activity, helping us understand market developments.   

This power is intended to be used as a proportionate, information-gathering tool, which may inform our assessment of whether further intervention is necessary.  

Regulation 15 – Power to prohibit or impose conditions on short selling  

Regulation 15 provides us with the ability to take direct action to restrict short selling activity.  

This includes the power to:  

  • Prohibit short sales, including through temporary bans.   
  • Impose conditions on short selling transactions or related activity.   
  • Apply measures to transactions beyond traditional short sales, where these provide economic exposure to falling prices.  

These powers may be exercised where we consider it necessary to respond to events or developments that pose a serious threat to financial stability or market confidence in the UK.   

Such measures may have implications for liquidity and market efficiency and will therefore be applied only where proportionate to the risks identified.  

Regulation 17 – Power to restrict short selling following a significant price fall  

Regulation 17 provides a targeted intervention mechanism where there is a sharp fall in the price of a financial instrument.  

Under this provision, we may:  

  • Restrict or prohibit short selling in a specific instrument where there has been a significant price fall on a UK trading venue relative to the previous trading day’s closing price.   
  • Apply such measures where it is appropriate to prevent a disorderly decline in price.   

We will assess price movements against defined thresholds for significant price falls and consider whether market conditions are becoming disorderly before intervening.  

Together, these powers are intended to allow us to respond proportionately to evolving market conditions, while maintaining confidence in the integrity and effective functioning of UK markets.  

Emergency Powers Notice

Where we exercise our emergency powers, we will publish a formal notice setting out:  

  • the powers used and measures imposed;  
  • the financial instruments or transactions to which the measures apply;  
  • the duration of the measures; and  
  • the reasons for our decision, including our assessment of proportionality. 

We will seek, where possible, to communicate our decisions in advance of implementation, to provide firms with appropriate time to prepare.  

 

 

 

New inside information declaration form for listings submissions via ESS

We're making an improvement to our document review submission requirements. We’re refining the arrangements that are in place for declaring whether inside information is present in documents submitted for review via the Electronic Submission System (ESS) portal. We’re bringing in a clear, simple inside information declaration form, available on our website here.

We’re making this improvement because the existing process was proving to be inefficient in identifying quickly when inside information was being included in the submission. It is vital we know whether submissions contain inside information so that we can apply the right internal controls. Providing clarity to us up front on how the FCA should handle the information removes the need for us to go back and check with submitters, and frequent altering of handling controls. This will make the overall process more efficient for us and for issuers and their advisers. 

This will apply to all new equity cases (including guidance requests) submitted through the ESS portal from Monday 21 September 2026. The new form must be included with the first submission of documents. Submitters must state on the form whether the submission contains inside information and if so, provide details of what the inside information is. Please note that without this declaration we will not be able to allocate the case for review.

If you have any comments or queries, please email [email protected].
