1: Overview

This CP^{footnote [1]} sets out the proposals of the FCA and the Bank (together ‘the regulators’) to implement and operate the Digital Securities Sandbox (DSS). These proposals comprise the regulators’ joint approach to:

1. The implementation and operation of the DSS.
2. The application process to enter the DSS.
3. The use of rule-making powers.
4. Approach to managing financial stability and market integrity risks in the DSS.
5. Supervision and enforcement.

These proposals also comprise the Bank’s approach to:

1. Fees levied by the Bank.
2. Managing the limits on DSD activity within the DSS.

This CP follows His Majesty’s Treasury’s (HMT’s) response to its consultation on the DSS Opens in a new window, which was published in November 2023. In its response, HMT confirmed the scope of the DSS, which will allow for the use of developing technology, such as distributed ledger technology (DLT), in the undertaking of financial market infrastructure (FMI) activities, specifically those traditionally performed by a central securities depository (CSD) (notary, settlement and maintenance of securities) and the operation of a trading venue.^{footnote [2]} In acknowledgment that the current framework for the operation of a CSD was not designed with the use of developing technology in mind, a new category of firm was created for the purpose of the DSS. To perform one, or a combination, of the activities of a CSD in the DSS, a firm will apply to be a Digital Securities Depository (DSD).^{footnote [3]} HMT provided for this through the DSS Regulations by creating a temporarily modified legislative and regulatory framework (modified framework). Since the Bank supervises CSDs, while the FCA supervises the operation of trading venues, the DSS and sandbox entrants will be jointly overseen by both regulators.

This CP will affect, and should be read by, firms intending to apply to enter the DSS and be approved as a sandbox entrant. It will also be of interest to firms who wish to engage with a sandbox entrant but not become one themselves, such as the prospective members of a DSD in the DSS, or a firm seeking to offer custody services for the digital securities that are recorded, traded or settled on those FMIs.

There will be no obligation for firms to participate in the DSS. Firms wishing to undertake the activities of a CSD outside the DSS would need to comply with existing regulatory requirements. However, if firms wish to operate an FMI under the modified framework, they will first need to apply to the regulators to become a sandbox entrant. Firms that do not require the modified framework to operate their business models should do so outside the DSS.

A draft guidance document is also included in Appendix A and should be read alongside this CP. This sets out how the DSS will operate and what firms looking to apply to the DSS can expect. We welcome feedback on the contents of this guidance document, including areas where additional guidance is required.

Responses and next steps

This consultation closes on 29 May 2024. The eight-week consultation period reflects the fact that the DSS rules do not represent a permanent regime and that the rules can be amended during the lifetime of the DSS as firms and regulators learn about the application of new technology in practice. This will allow regulators to support firms wishing to innovate by promptly updating rules and guidance. The regulators invite feedback on the proposals set out in this consultation. The regulators also invite stakeholders to bring to our attention any relevant issues that are not addressed in the proposals set out in this CP. Please address any comments or enquiries to DSSCPResponses@bankofengland.co.uk or cp24-5@fca.org.uk.

Please indicate in your response if you believe any of the proposals in this CP are likely to impact persons who share protected characteristics under the Equality Act 2010, and if so, please explain which groups and what the impact on such groups might be.

Table A below shows key terms used in the rest of this document. A glossary is also included at the bottom of this webpage for a full list of defined terms.

Table A: Key terms used in the CP

Term	Definition
Digital securities	The financial instruments in scope of the DSS are specified in Regulation 3(7) of the DSS Regulations Opens in a new window and defined as ‘FMI sandbox instruments’. For the purposes of this CP, such financial instruments are referred to as ‘digital securities’.
Sandbox entrant	This ‘catch all’ term is used to refer to a firm which has been approved to enter the DSS, irrespective of that firm’s business model or the stage they have reached in the DSS.
Digital Securities Depository (DSD)	This term is used to refer to a sandbox entrant which has been permitted to undertake the activities traditionally performed by a CSD, which results in it being a ‘DSD’. References to a DSD include a firm which undertakes other regulated activity alongside its DSD operations, both inside and/or outside the DSS.
Hybrid entity	This term is used to refer to a sandbox entrant which combines the roles of a trading venue and the activities traditionally performed by a CSD into one FMI. Such a firm would be both a DSD and have authorisation to operate a trading venue. This business model is explained in further detail below.

Footnotes

• Note: a reference to a DSD includes any firm in the DSS that has permission to undertake the activities of a CSD, whether as a standalone entity or one that also has permission to operate a trading venue as a hybrid entity.

2: Introduction

In the evolving landscape of global finance, the intersection of traditional financial systems with digital innovations presents both opportunities and new challenges. The use of new and innovative technologies in global finance can create a more efficient, competitive, and robust financial system that helps facilitate economic growth.

The adoption of new technologies has a long history of transforming financial markets in the UK. The transformation from paper-based exchanges to digital trading platforms revolutionised how securities are traded. Today, investors have a growing choice of trading venues, many of which employ innovative technology to streamline their services and therefore increase the efficiency and integrity of these markets.

Despite these advancements, the post-trade environment remains encumbered by sequential, often manual processes that are time-consuming, costly and operationally risky. The current system, while efficient in execution (ie, entering or agreeing a trade), can lead to a build-up of credit risk due to settlement periods, the involvement of multiple intermediaries and operationally cumbersome processes. These pose financial and operational challenges for financial market participants – including financial intermediaries such as banks and end-investors such as pension funds – and impose a cost to them in utilising these markets. The introduction of securities on distributed ledgers – digital securities – offers the potential to consolidate trade and post-trade functions and reduce settlement times. This could significantly reduce the number of intermediaries, streamline processes, and diminish systemic risks, thereby enhancing the overall resilience of financial markets.^{footnote [4]} Furthermore, the deployment of smart contracts on DLT introduces the possibility of new programmability and functionality in financial transactions, offering a more efficient, cost-effective, and transparent trading ecosystem.

These technologies need to be introduced in a way that protects the FMI that is at the heart of the financial system. Therefore, HMT, under the Financial Services and Markets Act 2023 (FSMA 2023) Opens in a new window, has been given the power to make provision for FMI sandboxes via statutory instruments. FMI sandboxes allow firms to experiment with new or different practices and developing technology in the key functions of FMI in a safe regulatory environment under temporarily modified legislation.

Recognising the potential of digital securities, the DSS is the first of these sandboxes in the UK. It focuses on the use of developing technology, such as DLT, in the undertaking of financial market activities traditionally performed by a CSD (notary, settlement and maintenance of securities) and the operation of a trading venue. In facilitating the application of developing technology to these activities, the DSS will offer greater efficiencies in the trading and settlement of securities to users of these financial markets. However, recognising that some of these developing technologies could increase risks, the Government and regulators have decided to explore this in the DSS first.

The three primary aims of the DSS outlined by HMT in its consultation^{footnote [5]} in July 2023 were:

1. Testing how existing UK legislation needs to change to accommodate digital asset technology and the new practices associated with it.
2. Enabling the financial sector to test and adopt digital asset technology in FMIs.
3. Testing the use of FMI sandboxes as a policymaking concept.

Following its consultation response in November 2023, HMT laid the Financial Services and Markets Act 2023 (Digital Securities Sandbox) Regulations 2023 Opens in a new window (DSS Regulations), which commenced on 8 January 2024. The DSS Regulations created the temporary framework under which sandbox entrants will operate and through which the regulators will implement and operate the DSS. This includes giving the regulators the powers to:

• establish an application process;
• maintain arrangements for the joint supervision of the DSS by the regulators, which includes the oversight of sandbox entrants;
• make, modify and disapply rules for sandbox entrants;
• modify and disapply existing technical standards; and
• put in place limits on overall activity in the DSS.

The outcome we are seeking to achieve

In implementing and operating the DSS, the regulators have three overarching aims in line with their statutory objectives:

• Facilitating innovation to promote a safe, sustainable and efficient financial system: the DSS facilitates the use of developing technology, such as DLT, for firms undertaking the activities of a CSD and operating a trading venue by removing potential barriers and obstacles.
• Protecting financial stability: the use of developing technology, such as DLT, has the potential to change settlement by offering increased speed and efficiency, while potentially removing the need for intermediaries. However, it remains untested at scale in traditional FMIs and opportunities to test it in systemically important financial activities have often not been permitted. It is therefore important to use the DSS to explore if and how to mitigate the potential risks to financial stability arising from the use of developing technology and/or the modified framework under which firms will operate in the DSS.
• Protecting market integrity and cleanliness: UK wholesale markets benefit from a regime that ensures market integrity and cleanliness. While making the changes necessary to enable the adoption of developing technologies, such as DLT, the proposed approach continues to provide for the integrity and cleanliness of our markets.

Some of the proposed key design features of the DSS to deliver on these aims are:

• The DSS should be proportionate and flexible to accommodate a variety of business models.
• In order to protect financial stability, the activities in the DSS normally undertaken by a CSD should be subject to limits.
• There should be a glidepath for sandbox entrants to move from operating within the DSS to operating outside of it under a possible new permanent regime, mitigating the risk of a regulatory cliff edge.
• Activity undertaken in the DSS will be ‘live’ and the financial system should be able to interact with sandbox entrants and digital securities in broadly the same way it does with conventional FMIs, subject to existing requirements where activities are not in the scope of the DSS.

While the DSS will allow for live activity in financial markets, it is by its nature an exploratory environment. As HMT stated in its consultation response, the Government has the tools to put in place permanent changes reasonably quickly. However, the specific nature of such changes is uncertain and will depend on the outcome of activity in the DSS.

The regulators and HMT will learn from the activity in the DSS and intend to create a new permanent regime which applies to the wider market. It is the shared intention of the regulators and HMT to design the DSS such that it is not a bridge to nowhere. However, there is no guarantee that individual sandbox entrants will emerge from the DSS with permission from regulators to operate outside of it. Permission to operate outside the DSS will only be granted to those applicants meeting the relevant standards. Persons that interact with sandbox entrants (for example to issue or trade securities on the FMIs they operate in the DSS) should take note of the above and consider the temporary nature of the DSS when engaging with a sandbox entrant.

The Bank is continuously developing wholesale payments. Alongside the new omnibus accounts available as part of the Banks’ Real-Time Gross Settlement (RTGS) service, the Bank is exploring as part of its future roadmap for RTGS the possibility of using a synchronised settlement interface to allow RTGS to interoperate with other ledgers (such as digital securities ledgers in the DSS). Alongside the DSS, this places the UK in a strong position to create an end-to-end digital wholesale infrastructure that embraces new technology and deliver greater efficiencies to financial market participants.

3: Joint Approach to the Digital Securities Sandbox

The DSS is jointly overseen by both the Bank and the FCA. The approach to how the regulators will jointly operate and supervise the DSS will depend on the combination of activities that firms undertake in the DSS.

Potential models in the DSS

The DSS Regulations allow for three possible business models: (1) undertaking the activities of a CSD by being a DSD; (2) operating a trading venue; or (3) combining both into one FMI to create a hybrid entity.

Undertaking the activities of a CSD as a DSD (notary, maintenance and settlement).

HMT’s consultation in July 2023 highlighted that the key potential legal and regulatory barriers and obstacles to using developing technology such as DLT in FMIs were primarily in relation to the activities of a CSD. Traditionally, a CSD has been a large entity that centralises and manages settlement risk across key financial markets. CSDs are typically systemically important, and this is reflected in the approach taken to their regulation and supervision. As such, under the unmodified framework, firms wanting to undertake the activities of a CSD must be authorised as such. The current process and requirements for authorisation as a CSD are extensive and compliance with them can be challenging for new entrants. The relevant enactments also assume that firms operate a traditional ‘book entry’ ledger system, which may not be compatible with the use of developing technology such as DLT.

The Bank’s approach to the DSS looks to address these barriers and obstacles by allowing firms performing one, or a combination, of the activities of a CSD in the DSS to apply to be a DSD and making the supervisory and regulatory requirements for DSDs more proportionate to the financial stability risks they pose given the scale and the type of technology. This means that in the early stages some requirements will be lower and will then increase proportionately to the financial stability risks as firms scale. In order to protect financial stability when requirements are temporarily lower, the Bank proposes to also impose temporary limits on activity in the DSS.

Operation of a trading venue

The framework governing the operation of a trading venue has not been modified for the purposes of the DSS. As HMT noted in its consultation response, feedback from industry largely did not suggest that particular changes were needed to UK Markets in Financial Instruments Regulation (MiFIR), or the wider framework that applies to the operation of a trading venue.

Of the issues that were raised, it was determined that these did not pose significant barriers that are likely to uniquely affect the use of developing technologies for the operation of a trading venue. In the light of the above, the FCA considers it unlikely that a firm only intending to operate a standalone trading venue would be accepted into the DSS as a sandbox entrant, as such a firm would need no modification to regulation in order to operate. If a firm did consider that it requires the modified framework in order to realise its optimal business model, the FCA would consider that application on a case-by-case basis. By maintaining the existing framework, the FCA also aims to facilitate the ability for activity in the DSS to interact smoothly with the wider financial services ecosystem

Hybrid entity

The DSS Regulations, through the disapplication of Article 18 UK Central Securities Depositories Regulation (UK CSDR) (the effect of which is to prevent a CSD from also undertaking non-CSD activities), allow for the creation of a hybrid entity which combines the roles of operating a trading venue and operating the activities traditionally undertaken by a CSD (and in the DSS, a DSD). A firm that operates as a hybrid entity will be supervised by the FCA for its operation of a trading venue, and by the Bank for the operation and activities traditionally conducted by a CSD (Figure 1). Where a firm undertakes its DSS activity from the same entity as other regulated activities not in scope of the DSS, it will continue to be supervised by the appropriate regulator in the usual way for those other activities.

Figure 1: Roles of the Bank of England and FCA in the DSS

Notwithstanding the above, HMT’s consultation response stated that the government will keep the scope of the DSS, including whether further legislation needs to be brought into scope, under review. Where new barriers or obstacles are identified, firms may approach the regulators, and these will be considered on a case-by-case basis. One area raised by industry in response to HMT’s consultation was the application of the Money Laundering Regulations 2017 to DSS activity. The regulators are working with HMT to determine whether and how this should be addressed.

Glidepath to operation outside the DSS under a new permanent settlement regime

As set out above, a sandbox entrant that intends to undertake the activities of a CSD, including when combining them with a trading venue to be in a hybrid entity, will need to apply to be a DSD. Equally, a firm which wishes to operate a trading venue in the DSS will need to have the necessary authorisations or exemptions to do so. The DSS permits activity in a broad range of securities and will have overall limits within key sterling assets classes at a minimum (the Bank may consider introducing limits for other asset classes if justified).

The DSS is composed of different stages of permitted activity, reflecting the Bank’s approach to managing financial stability risks. There will be a series of gates for sandbox entrants to move through to progress from one stage to the next, with the amount of permitted activity increasing with each stage. This glidepath will enable sandbox entrants eventually to graduate from the DSS to a possible new settlement regime, if they meet the relevant standards. In the case of a DSD (or, as explained above, a hybrid entity in so far as it concerns the operating firm’s DSD activities), each stage will have higher regulatory requirements (proportionate to the financial stability risks) which the sandbox entrant will be assessed against before being permitted to progress and conduct additional activity. Box A and Figure 2 summarise these different stages and gates of the DSS.

4: Proposed approach to Gate 1

Gate 1 criteria and application

The DSS Regulations specify the following types of FMI entity, where they are established in the UK, are eligible to apply to become a sandbox entrant:

1. a recognised investment exchange that is not an overseas investment exchange;
2. a recognised CSD;
3. a person who has a Part 4A permission to operate a MTF and is an investment firm; and
4. a person who has a Part 4A permission to operating an OTF and is an investment firm.

The DSS Regulations also allow the regulators to further determine that other persons established in the UK can apply to become a sandbox entrant. Consequently, the regulators propose to open the DSS to persons otherwise specified in the DSS Regulations, to apply to be a sandbox entrant.

The DSS is open to existing financial institutions or new entrants to this market. The regulators are open to applications from firms of all sizes and at all stages of development. However, they must be legal persons established in the UK and obtain the relevant authorisation or permissions before undertaking any regulated activity.

Furthermore, the DSS Regulations give the regulators the power to determine an application process for firms that apply to become a sandbox entrant. While much of the eligibility criteria is already specified by the DSS Regulations, namely the type of entity eligible to apply, the requirement for applicants to be established in the UK, and the FMI activities and financial instruments in scope of the DSS, the regulators can specify the information accompanying the application to determine the eligibility of the applicant.

The regulators propose to require firms to identify the regulatory or legal barriers and/or obstacles to using developing technology such as DLT which prevent them from operating their optimal business model outside of the DSS. This will help focus the DSS on those business models which do need modifications and allow the Government and regulators to better assess what permanent legislative and regulatory changes are needed to allow for a more widespread adoption of these new practices or developing technologies.

The regulators propose to consider the supervisory record of applicants and any past enforcement action taken against them. If the regulators become aware of any adverse information, this information will be taken into account and can result in the rejection of the application. This approach will contribute towards increasing trust in and the reputation of UK financial markets.

The regulators also propose to require a consortium of firms who wish to apply together to operate an FMI within the DSS to establish a single UK entity. The regulators consider this approach to be necessary because the DSS is designed so that only the operator of the FMI needs to become the sandbox entrant, so it would not be practicable for this to be a consortium of firms.

As part of their DSS application, firms should inform the regulators of non-DSS activities they intend to operate from the same entity. Regulators may take this into account when considering the application. During the course of the DSS, if the firm's non-DSS activities change materially, the regulators should be informed.

Proposed approach to rules in the DSS

Background

The DSS Regulations made targeted modifications to Regulation No. 909/2014 (UK CSDR), FSMA 2000, Uncertificated Securities Regulations 2001 (USRs 2001) and Companies Act 2006 (CA 2006). These were made to facilitate the use of developing technology such as DLT for the operation of a trading venue and undertaking the activities of a CSD, and to give the regulators the powers to implement and operate the DSS. A key feature of the DSS Regulations is that some requirements placed on firms in legislation governing CSDs have been disapplied.

Specifically, the DSS Regulations give the regulators the power to make rules applying to sandbox entrants and other persons engaging in DSS activity, but which are not themselves a sandbox entrant (see Regulation 3(4) of the DSS Regulations) as appears necessary or expedient in order to implement and operate the DSS. This includes the power to waive or modify a rule for an individual entity or a class of entity.

Under the modified framework, the regulators have the power to:

• make rules, including to replace requirements placed on firms disapplied by the DSS Regulations;
• waive or modify rules including those made under FSMA 2000 or other relevant enactments;
• provide for the application of existing rules to sandbox entrants of a specified description or for individual sandbox entrants; and
• modify (including the power to provide for them not to apply) technical standards.^{footnote [8]}

This section of the CP explains how regulators propose to use these broad rulemaking powers to operate the DSS.

This breadth of the regulators’ rulemaking powers reflects the need for flexibility in the DSS. The regulators may need to update the regulatory framework as they learn from the activity, technology and business models of sandbox entrants, in order to provide a glidepath to a possible new permanent regime. The regulators may need to temporarily relax certain requirements to allow firms to scale up their operations gradually. Additionally, the regulators may need to adapt rules to specific sandbox entrants to reflect their technology and/or business models, although the bar for this will be high.

The regulators are alive to the possibility that, as sandbox entrants commence live activity in the DSS, they may identify further barriers that prevent them from realising their optimal business models. Firms may approach the regulators in these instances and the barriers identified will be considered on a case-by-case basis. If it is determined that a barrier might be removed while maintaining good regulatory outcomes, the regulators may consider doing so, while not being able to guarantee that this will be carried through to any new future permanent regime.

Bank rules

The Bank proposes to use its flexible rulemaking powers to create ‘Bank’s DSS rules’ which will contain the rules that will apply to DSDs after Gate 2 and the ‘end-state’ rules which are the Bank’s ‘default’ of what it anticipates the future requirements placed on firms may look like. The end-state rules themselves can be found in Appendix B. In addition, please refer to Appendix C for a comparison of the requirements that will apply to firms at Gate 2 and our end-state rules.

The SAN – that will act as a ‘visa’ for firms participating in the DSS – will specify which set of rules apply to DSDs at a given point in time and can also specify any modifications or waivers granted to them by the Bank, alongside other relevant information. By studying the Bank’s DSS rules (alongside the DSS CSDR and DSS USRs) and the SAN of a sandbox entrant, users of a DSD and broader market participants will be able to see the regulatory requirements that individual DSDs are being held to at a particular point in time.

The Bank will reserve the right to make changes to the rules that apply to DSDs across the different stages of the DSS and may vary requirements imposed on individual DSDs as the regulators learn from the DSS. To preserve financial stability, the Bank may choose to tighten the rules for DSDs if it finds there are new risks from the combination of technology and business models in the DSS. Conversely, the Bank may also disapply or make more proportionate certain rules if it finds that risks are lower than anticipated. The Bank will consider any proposed changes to rules carefully and will endeavour to balance the need to create a predictable operating environment for sandbox entrants while continuing to meet its primary objective of protecting financial stability.

The Bank’s approach to creating the end-state rules

The ‘end-state’ rules have been drafted to maintain broadly equivalent regulatory standards as those in CSDR and the USRs. However, where the wording of certain provisions appears to be potentially incompatible with the use of developing technology such as DLT, those provisions have been adapted. The aim of the end-state rules is to shed light on the regulatory standards that will need to be met by DSDs that wish to operate under a possible new permanent regime after the DSS.

As stated above, the DSS Regulations disapplied the requirements placed on firms in CSDR and the requirements placed on issuers and operators of ‘relevant systems’ in the USRs, against which the Bank also supervises CSDs. Using its rule-making powers, the Bank proposes to reinstate the requirements placed on firms into its end-state rules while removing known regulatory barriers to innovation and making some consequential changes, but without diluting the standards in those regulations.

Finally, the Bank proposes to bring across a limited number of the requirements placed on firms that were in the CSDR Regulatory Technical Standards (RTS) into Bank rules to maintain the level of detail for those standards where it deems it appropriate. These include RTS for capital requirements and for CSD links (a CSD link is an arrangement between two CSDs that allow clients of one CSD to access and trade securities in another CSD without being a direct participant in both CSDs), whereas the rest of the RTS will be disapplied.

The regulators are unlikely to anticipate all regulatory barriers and novel issues and risks posed by new business models before the DSS opens. This goes to the heart of objectives of the DSS. The Bank can use its powers to continue to evolve the Bank’s DSS rules as it learns from the experience of the DSS, both to remove regulatory barriers and to address new risks from new technologies and business models. By evolving its rules over the life of the DSS, the Bank aims to provide a glidepath for sandbox entrants and market participants towards a possible new permanent regime.

The regulators would expect the Bank’s end-state rules to be modified based on any learnings from the DSS. It should be noted that the FCA is not consulting on its approach to rules under a possible new permanent regime as the industry has not highlighted any required changes to the FCA’s existing regime. There is therefore no guarantee that the end-state rules would apply in their current form to a sandbox entrant that left the DSS at the end of its term. However, the intention is that sandbox entrants which meet the requirements of any new permanent regime would be able to apply to continue activity outside the DSS. The Bank has chosen to consult on the Bank’s DSS rules ahead of the DSS opening. It is possible that the Bank may choose not to do so in future due to the temporary nature of the DSS and for the need for regulators to remain agile. See [Appendix B] for the full end-state rules.

The Bank’s approach to creating the Gate 2 rules

The Bank also proposes to use its powers to put in place modified rules at Gate 2 and Gate 3. At Gate 2, these modified rules will represent fewer requirements than those applied at later stages, reflecting the lower financial stability risk. The limits on the activity of DSDs allow the Bank to temporarily lower regulatory requirements, allowing them to scale their business while maintaining minimum guardrails appropriate to their activity to mitigate financial stability risk. Please refer to Appendix C for a comparison of the requirements that will apply to firms at Gate 2 and our end-state rules. The Bank’s rules in place at Gates 2 and Gate 3 will be lower relative to CSDs operating outside of the DSS, including standards such as those contained in the CPMI IOSCO Principles for Market Infrastructures (PFMI) Opens in a new windowas a consequence of the limits being applied. This means that users of DSDs and wider market participants should expect a higher risk of failure and operational disruption relative to activity outside of the DSS. However, any broader, systemic disruption from DSS activity will be contained as long as DSDs stay within their limits and are able to wind down their DSS activity safely. The Bank will supervise DSDs to achieve this.

The Bank proposes to create Gate 2 rules by:

1. Applying some end-state rules in full.
2. Disapplying some end-state rules and replacing them with more proportionate Gate 2 rules.
3. Disapplying some end-state rules and not replacing at Gate 2 in any form.

While some sandbox entrants may need to make investments or adjustments in order meet Gate 2 requirements, the Bank considers these requirements to be necessary to ensure DSDs meet minimum standards to operate in the DSS. Firms will need to meet Gate 2 requirements in full to conduct live business as a DSD. There may be a limited set of circumstances where firms have identified specific features of their technology and/or business models that will render them unable to meet Gate 2 rules. Firms should provide evidence so that the Bank can consider whether there is a case to vary the way rules apply to an individual firm, including through providing a waiver. The bar for this is likely to be high.

See Appendix B for the full Gate 2 rules.

Application of Bank, PRA and FCA rules to hybrid entities

One of the objectives of the DSS is to allow firms to experiment with different business models, potentially combining activities that are required to be legally separate under existing legislation, such as the operation of a hybrid entity to provide for the trade and settlement of securities.

It is also possible that a bank applies to participate in the DSS with the intention of continuing its existing banking activities alongside operating a DSD or hybrid entity as described above, without creating a separate entity to undertake DSS activities. UK CSDR prevents the comingling of commercial banking activities with CSD activities, requiring instead a stand-alone banking entity to be set up which undertakes only banking activities for the CSD. The Bank is proposing to disapply the relevant requirements at Gate 2 to allow this comingling. In the interest of clarity, the Bank is only proposing to relax this requirement at Gate 2 where activity is subject to strict limits – the requirement to separate regular banking activities from CSD banking activities remains in place at end-state. This creates another potential area of overlap between Bank’s DSS rules and the PRA regulatory framework for banks (which includes PRA rules).

The regulators are aware that in some cases there may be overlaps across the different regimes which apply to a sandbox entrant. The regulators recognise that firms may have questions about how the different rules that apply to them will interact and encourage such firms to discuss these questions with them at the early stages.

Sandbox entrants will be required to meet all applicable rules and/or requirements relating to the regulated activities they undertake, whether within or outside the DSS. The Bank’s DSS rules will apply to sandbox entrants that are (i) DSD-only and (ii) a hybrid entity in so far as it concerns being a DSD. The Bank’s DSS rules apply only to activities undertaken in the DSS and not to any activity outside of it. In general, the scope of the Bank’s rules is limited to a DSD’s activities of notary, settlement, and maintenance. However, the Bank proposes that the scope of the rule on capital (Article 47 in draft Bank’s DSS Rules) is broadened to ensure that sandbox entrants take account of all activities that take place inside the DSS in the capital calculation.

Subject to the above, the regulators’ intention is to ensure that requirements are proportionate to the risks and to avoid introducing any duplication of requirements because of firms’ participation in the DSS. For instance, sandbox entrants may already be meeting specific regulatory and supervisory outcomes relating to the DSS through ongoing compliance with requirements that apply to their other regulated activities. In such instances, the regulators have powers to waive or modify rules that apply to a sandbox entrant on a case-by-case basis.^{footnote [9]}

Approach to capital requirements in the DSS

To pass Gate 2 and commence live activity, all sandbox entrants will have to hold sufficient resources to cover the risks of participating in the DSS. The requirements a sandbox entrant must meet will depend on its business model and the activities it proposes to undertake.

Bank’s capital requirement for DSDs

DSDs will be required to comply with the Bank’s DSS rules relating to capital requirements. Article 47 in its end-state form contained in the Bank’s DSS rules is in line with current requirements that CSDs must meet under Article 47 of UK CSDR, including the associated Regulatory Technical Standards that provide the detailed requirements for calculating both going-concern capital and the wind down costs.

However, at Gate 2, Article 47 will be less prescriptive relative to the end-state. While DSDs may choose to use the methodology prescribed in the end-state rules, they will also be able to use their own approaches and assumptions to calculate the level of capital they are required to hold at Gate 2 as set out in Article 47. This level of capital should be sufficient at all times to cover the main risks arising from their DSS activity when a going concern and to wind down their DSS activities in an orderly way. The Bank does not propose to prescribe a methodology for this calculation at Gate 2 but will review firms’ approaches and use these as input in determining the appropriate requirements.

The Bank proposes that at Gate 2, as a minimum, DSDs hold the higher of: (a) the amount of resources needed to cover all their going concern risks and the cost of wind down or (b) resources equivalent to at least nine months’ operating expenses for their DSS activities at all times, in order to cover the risks from these activities.

Consistent with the principles set out above, a DSD which is also subject to FCA or PRA capital requirements due to other regulated activity will need to meet both the applicable FCA/PRA requirements and the Bank’s DSS rules on capital requirements for its DSS activities.^{footnote [10]} The regulators’ intention is that a sandbox entrant holds sufficient capital to cover both the going concern risks and the cost of winding down all its activities in the DSS, and, in addition, to satisfy its requirements for any regulated activity outside of the DSS (where relevant). This will ensure that the sandbox entrant can operate safely in the normal course of business and provide for an orderly wind down of all DSS activities if the circumstances required. The regulators will also have the powers to waive or modify Bank’s DSS rules on a case-by-case basis if they create unforeseen disproportionate interactions with other capital requirements. The regulators will look to ensure that firms’ requirements are proportionate to the risks from DSS activities while aiming to avoid double counting of capital.

5: Approach to managing financial stability and market integrity risks in the DSS

The key financial stability risk from the DSS is the potential for large-scale failures in the recording, trading and settlement of securities, causing a wider market impact. While key protections around operational resilience and wind-down planning will be in place for the DSS, developing technology such as DLT remains novel and untested at scale, particularly in traditional markets. As discussed above, the Bank will also allow sandbox entrants to undertake the activities of a CSD while meeting a modified set of regulatory standards. In addition to this risk, the use of developing technology such as DLT may enable new business models which, while potentially offering benefits in terms of innovation, could give rise to novel financial stability risks (for example from the use of instant settlement). The risks are therefore uncertain relative to established practices and strict limits will be necessary, especially in markets which are key to the functioning of the wider financial system.

To manage financial stability risks, the Bank will place limits on the activity of DSDs in the DSS, while the FCA’s approach is intended to mitigate any risks to market integrity by ensuring that the operator of a trading venue inside the DSS must meet the same standards as an operator outside of it. By retaining the existing framework, the FCA will provide for the orderly operation of financial markets and protect against financial crime and market abuse. Current investor protections will also apply equally to FCA-regulated activities in the DSS.

Scope of financial instruments in the DSS

The digital securities in scope of the DSS are all financial instrument types listed in the Regulated Activities Order (RAO), with the exception of derivatives.^{footnote [11]} This includes transferable securities (eg, equities and bonds), money market instruments, units in collective investment undertakings (fund units), and emissions allowances. Other assets not covered by the RAO – including unbacked cryptoassets such as Bitcoin – are not in scope of the DSS. Firms that wish to settle such assets should plan to conduct this activity outside of the legal entity from which the DSD is operated.

Prospective participants in the DSS, both sandbox entrants and other firms looking to issue digital securities, should note the requirement under Article 3 of UK CSDR for financial instruments defined as transferable securities^{footnote [12]} that are traded on a trading venue (such as on an MTF or on a regulated market) or in financial collateral arrangements to be recorded in a book-entry form at a central depository. For digital securities being issued utilising developing technology such as DLT, this central depository would be a DSD in the DSS. Firms looking to issue digital securities and prospective DSDs should take care to understand whether a digital security being issued would be caught by this requirement.

In general, digital securities in the DSS can be used in wider financial market activities, including for example in securities financing transactions, or as collateral, in line with regulations covering these activities. However, this should be in line with market best practice and take place under established market legal frameworks.^{footnote [13]} However, regulators may choose to restrict these uses if financial stability concerns arise.

Aggregate limits in the DSS

The Bank is proposing overall capacity limits for established key sterling asset classes. Trading and settlement for other asset classes will also be possible in the DSS, but limits on those activities would require further discussion with firms on the detail of their proposals and potential impact to financial stability.

Table C outlines the overall capacity of the DSS for established, key sterling asset classes – gilts,^{footnote [14]} corporate bonds, asset-backed securities, money market instruments (commercial paper and certificates of deposits), and FTSE 350 equities. The limits are expressed as a range to provide the Bank with the necessary tools to manage limits for individual DSDs within the overall capacity, as well as ensure that financial stability risks are contained as the regulators learn more about the risks of the activity taking place in the DSS. These will be based on a variety of factors, including, for example, observed risks of activity (both in the creation of digital securities and their utility), resilience of sandbox entrants, and the number of sandbox entrants progressing beyond Gate 2. As firms move to Stage 3 (‘Go live’), the Bank will distribute the capacity among DSDs who wish to trade or settle specified sterling asset classes based on the lower bound of the limit range. However, as the DSS matures, the Bank may decide to allocate based on overall capacity further into the range, up to the upper bound of the limits subject to considerations around financial stability.

Given the risk profile and market of each asset class is different, the management of limits in the DSS will vary depending on the asset class and, in some cases, the specific characteristics of the security – for example, the tenor or credit rating of the asset. For example, in the case of sovereign debt issuance, the Bank will also consider whether limits may be justified on specific tenors, reflecting the importance of gilts and specific tenors for financial stability and monetary policy transmission. For financial instruments in scope of the DSS Regulations but for which a limit is not specified in Table C, the Bank reserves the right to assess the specific use cases and the potential impact on financial stability, and to set limits as required.

Limits will apply to the stock of both digitally native issuances and tokenisation of existing securities.

Initially, the Bank intends to limit the scope of assets to GBP-denominated assets only and for settlement to take place in GBP. However, it will review this restriction as it learns more about risks in the DSS. This reflects an expectation that firms operating in the UK would be focused primarily on GBP markets initially.

Table C: Aggregate limits for key asset classes in the DSS ^(a)

6: Approach to supervision in the DSS

Both the Bank and FCA tailor their supervisory approach to the risks posed by firms. Regulators also have access to existing powers under FSMA 2000 for the purpose of operating the DSS by consequence of the DSS Regulations.

Bank supervisors will assess DSDs against the relevant rules as part of the decision whether to allow them to go through Gates 2 and Gate 3. DSDs should not assume that passing through gates is automatic as this will depend on their progress against applicable requirements and related supervisory engagement. Firms will need to provide evidence that they are meeting all relevant rules at each stage. Supervisory assessment against the requirements will be proportionate to the size and risk of the business and may depend on the technology being used and the proposed business models. Regulatory requirements will grow as firms scale. Following a successful supervisory assessment against Gate 2 or Gate 3 rules, those rules will continue to apply until the firm is ready to progress to the next stage, including seeking authorisation under a possible new permanent regime.

An important difference between the Bank and FCA’s approach is that the operators of trading venues will need to meet the same standards as currently exist outside of the DSS. These are already designed to accommodate non-systemic firms. DSDs do not have to meet the same standards as are currently in place for CSDs. Instead, the Bank is putting in place proportionate standards for DSDs, which will change to reflect their progress in the DSS, and therefore their risks.

7: The Bank of England's proposed fee regime for firms/entities participating in the DSS

The DSS Regulations give the Bank powers to levy fees on applicants to the DSS and sandbox entrants in connection with the discharge of any of its functions relating to the DSS. The Bank has proposed a new fee regime for the DSS as this is a new function for the Bank. A new fee regime is required to allow the Bank to ensure it has the resources it needs to operate the DSS. The Bank is proposing a ‘Pay As You Go’ approach to levying fees in the DSS.

A sandbox entrant seeking authorisation to operate a trading venue in the DSS, specifically a MTF or an OTF, will be subject to the existing FCA fee regime. The current FCA application fees Opens in a new window for authorisation to operate an MTF or OTF of £50,000 will apply. A firm which already holds a Part 4A permission and which requires a VoP to operate an MTF or OTF in the DSS will need to pay the usual fee of £25,000. As described in Section 3, the FCA’s approach to implementing and operating the DSS will not require major regulatory changes or new processes. In consequence, FCA fees will not be amended. The FCA’s fees are therefore not subject to this consultation.

The effect of the Bank’s proposed fee regime is that a hybrid entity would be subject to the Bank’s fee regime to become a DSD and the FCA’s regime for its operation of a trading venue.

The Bank will consider its approach to fees for hybrid entities on an ongoing basis. An important consideration will be around the impact of a dual supervisory approach. There may be areas where Bank supervisors find efficiencies and avoid having to look at the same information separately (eg, around governance), thus reducing the amount of effort required. Given that it is not possible to estimate potential overlap at this stage, the Bank has made no adjustment for hybrid entities in this fee consultation but will explore whether a rebate is appropriate for hybrid firms and whether specific adjustments need to be made for such firms in the fee regime more generally.

9: Regulator compatibility statement

FCA compatibility statement

The FCA’s proposals set out in this consultation are primarily intended to advance the FCA's operational objective of enhancing market integrity. They are intended to achieve this by supporting market efficiency and effective competition to further the soundness, stability and resilience of the UK financial system. They will also provide for the orderly operation of financial markets and protect against financial crime and market abuse by ensuring that the operator of a trading venue inside the DSS must meet the same standards as an operator outside of it.

At the same time, this approach will also support the interoperability of digital securities by facilitating their interaction with the wider financial system. The FCA considers a strong participation in DSS FMIs to be important if the benefits of the DSS are to be realised. These proposals are also compatible with the FCA’s strategic objective of ensuring that the relevant markets function well.

These proposals will contribute to strengthening the UK’s position in global wholesale markets by supporting innovation in FMIs and the wider market while maintaining high standards of market integrity and consumer protection.

The DSS serves to advance the FCA’s secondary international competitiveness and growth objective by positioning the UK as one of the countries which has taken proactive steps to allow for the use of developing technologies such as DLT in traditional markets. The proposed approach, including the Gate 1 application process and criteria which is aimed at facilitating innovative business models, should allow for HMT and the regulators to more easily determine the permanent changes which are needed to accommodate a wider adoption of such technologies. The FCA’s adoption of a proportionate regulatory approach is supportive of its secondary international competitiveness and growth objective by enabling regulatory costs on firms to be proportionate to the expected benefits.

The FCA also aims to foster innovation by providing for a same risk, same regulatory outcome’ approach with regard to sandbox entrants’ technology choices. This technology-neutral approach will help to promote competition and positive change, however it will simultaneously provide for the setting and testing of higher standard by ensuring firms remain responsible for meeting the existing operational resilience requirements. As such the DSS will help the UK to play a leading role in setting international standards. Further, the draft guidance will ensure firms have clarity as to how they can apply to the DSS, the expectations and limits which will be placed on them and how the regulators will provide for financial stability and market integrity. This should give firms the confidence to participate in the DSS and contribute towards increasing trust in and the reputation of UK financial markets. This can in turn make the UK more internationally competitive.

In preparing the proposals set out in this consultation, the FCA has had regard to the following regulatory principles set out in section 3B FSMA.

The need to use our resources in the most efficient and economical way.

Where possible, the FCA has sought to leverage existing processes, which includes maintaining the current authorisation process for firms wishing to operate a trading venue.

The principle that a burden or restriction should be proportionate to the benefits.

The FCA has chosen to maintain the existing framework that governs the operation of a trading venue as it believes that this adequately accounts for any risks presented by firms’ activity in the DSS.

The need to contribute towards achieving compliance by the Secretary of State with section 1 of the Climate Change Act 2008 (UK net zero emissions target) and section 5 of the Environment Act 2021 (environmental targets).

The FCA has considered the environmental, social and governance implications of its proposals and its duty under section 1B(5) and 3B(c) of FSMA to have regard to contributing towards the Secretary of State achieving compliance with the net-zero emissions target under section 1 of the Climate Change Act 2008 and environmental targets under section 5 of the Environment Act 2021. Overall, the FCA does not consider that the proposals are relevant to contributing to those targets. The FCA will keep this issue under review during the course of the consultation period.

The general principle that consumers should take responsibility for their decisions.

The FCA does not believe the proposals in this consultation will affect the way in which consumers interact with the financial instruments in scope of the DSS and note that the trading venue access rules have remained unchanged for firms operating trading venues in the DSS.

The responsibilities of senior management.

As above, the FCA is maintaining the existing framework that governs the operation of a trading venue and therefore do not consider this to be relevant to our proposals.

The desirability of recognising differences in the nature of, and objectives of, businesses carried on by different persons including mutual societies and other kinds of business organisation.

The FCA does not expect the proposals in this paper to have a significantly different impact on mutual societies, nor on any other specific kind of business organisation.

The desirability of publishing information relating to persons subject to requirements imposed under FSMA or requiring them to publish information.

The FCA is maintaining its existing approach to supervision and enforcement and therefore does not consider this to be relevant to its proposals.

The principle that we should exercise our functions as transparently as possible.

This consultation sets out the FCA’s proposals to implement and operate the DSS. Any feedback will be considered before opening the DSS for applications.

In formulating these proposals, the FCA has had regard to the importance of taking action intended to minimise the extent to which it is possible for a business carried on (i) by an authorised person or a recognised investment exchange; or (ii) in contravention of the general prohibition, to be used for a purpose connected with financial crime (as required by section 1B(5)(b) FSMA). However, it does not believe that its proposals create any new risks in this regard.

The FCA has considered how its proposals and guidance will support the recommendations made by HMT under section 1JA FSMA 2000. Firstly, the FCA’s approach to implementing and operating the DSS will support the government’s objective of medium to long-term economic growth in the interests of consumers and businesses. It will do this by allowing a broad range of firms to take advantage of the opportunity which the DSS presents to test the use of developing technology such as DLT in traditional financial markets. To achieve this outcome, the FCA has designed its Gate 1 application process and criteria to be as streamlined and easy to navigate as possible, making it accessible for a diverse range of firms including small to medium-sized entities. By providing for a diversity of business models to enter the DSS, the FCA will be better placed to learn what permanent changes are needed to the regulatory framework. This separately furthers the government’s aim to deliver smart regulatory reform, and support innovation and new developments in financial markets.

The FCA has had regard to the FCA’s duty to promote effective competition in the interests of consumers and considers that by facilitating the use of new practices and business models it is promoting such competition.

The FCA has considered the equality and diversity issues that may arise from the proposals in this consultation paper. It does not consider the proposals to have any equalities impacts for persons who share a protected characteristic.

The FCA has had regard to the principles in the LRRA 2006 for the parts of the proposals that consist of general policies, principles or guidance and considers that it is providing for regulatory activities to be carried out in a way that is transparent, accountable, proportionate, consistent and targeted only at cases in which action is needed.

Finally, the FCA has had regard to the Regulators’ Code and considers its proposals to be compatible. The proposed approach to implement and operate the DSS is intended to allow for those regulated by the Bank and the FCA to comply and grow, while the approach to the supervision of sandbox entrants, including the new Memorandum of Understanding that will be agreed between the Bank and the FCA, will provide for the FCA to share information about compliance and risk as appropriate.

Bank of England’s Statutory Objectives

The learnings from the DSS will also serve to further the Bank’s secondary objective under FSMA 2023 in the long term to facilitate innovation in the provision of clearing and settlement services with a view to improving the quality, efficiency and economy of the services, while also maintaining resilience in those services in line with the Bank’s primary financial stability objective.

Bank Equality and diversity

The Bank is required by the Equality Act 2010 to have due regard to the need to eliminate discrimination and to promote equality of opportunity in carrying out its policies, services, and functions. The Bank considers that the proposals in this CP would not give rise to adverse equality and diversity implications.

At Gate 1, an applicant will be assessed against the eligibility criteria. At subsequent gates successful applicants will be required to demonstrate their enhanced ability to meet the expected regulatory standards to supervisors. Each gate has different requirements that are a pre-requisite to moving onto the next stage (see Appendix A for individual gate details).

Go live limit – The allocated portion of the overall capacity of the DSS that each DSD is given for certain asset classes once they have successfully got past Gate 2 and have been given permission to undertake live activities. There are rules (see draft Bank DSS Rules Instrument) that DSDs have to meet with respect to limits.

HMT – His Majesty’s Treasury.

Hybrid entity – A sandbox entrant which has been allowed to undertake both the functions of a trading venue and those traditionally performed by a CSD. Such a firm would be supervised jointly by the FCA and the Bank.
