On 1 October 2025 ministers, regulators and senior officials from the United Kingdom and the European Union met in the fourth session of the Joint EU–UK Financial Regulatory Forum — a now-regular channel established under the 2023 Memorandum of Understanding on Financial Services Cooperation. The meeting, held in Brussels, brought together senior figures from HM Treasury, the European Commission and the main regulatory authorities to review an intensive agenda that covered macro-financial stability, banking, capital markets, asset management, digital finance and sustainable finance. The joint statement published after the meeting framed the event as a pragmatic, technical dialogue aimed at reducing frictions between two of the world’s largest financial ecosystems while protecting financial stability.

This fourth forum follows three earlier rounds of engagement that have become an established fixture in post-Brexit EU–UK financial relations. It is an instrument both sides use to avoid unintended regulatory divergence that could amplify risk for markets and to exchange views on converging global standards. The October meeting — notable for its breadth of topics and the timing amid intensive regulatory change in both jurisdictions — demonstrated how the forum is evolving from an early confidence-building exercise into a platform for detailed technical co-ordination.

Why the forum matters
Since the UK left the EU institutions, financial regulation has been one of the most sensitive areas for future relations. The City of London remains a major global financial centre, while the EU is home to the world’s largest single market. Both have an interest in minimising disruption to cross-border banking, investment, and clearing. The forum’s significance is therefore practical: it offers a structured way to compare regulatory initiatives, identify areas where differences could influence market behaviour, and — where feasible — to cooperate on shared risks in the interests of financial stability. The most recent meeting underlined this by putting securitisation, derivatives clearing, digital finance and the green transition at the top of the agenda. (GOV.UK)
What happened at the fourth meeting — the agenda and outcomes
The official joint statement summarised discussions across six broad headings: macro-economic and financial stability outlook; banking (including resolution and Basel implementation); capital markets; asset management; digital finance; and sustainable finance. Each theme contained technical sub-items where the two sides exchanged policy updates, discussed timelines for legislation and regulation, and identified potential market-stability implications. The meeting aimed not to harmonise law (which neither side intended) but to increase transparency and predictability around regulatory choices. (GOV.UK)
Securitisation and capital-markets architecture featured prominently. The European Commission set out its reform proposals published over the summer of 2025 to update the EU’s securitisation framework; UK officials explained parallel evolutions in UK policy and the workstreams being advanced to ensure market functioning and appropriate investor safeguards. Both parties agreed to continue exchanging views as their frameworks evolve — a classic example of the forum acting as an early warning and co-ordination channel for potentially market-sensitive regulatory change. (Finance)
Another central area of focus was derivatives clearing and access to central counterparties (CCPs). With the global derivatives market concentrated in a handful of large clearing houses (notably in London), EU authorities have taken steps to encourage development of on-shore euro clearing capacity while also seeking to preserve financial stability. Participants in Brussels reaffirmed the mutual interest in avoiding abrupt fragmentation of clearing markets and underlined the importance of contingency planning and data exchange to manage spill-over risks. Observers noted that the forum’s dialogue helps to reduce policy uncertainty for banks and corporates that rely on cross-border clearing. (Financial Times)
Digital finance and crypto regulation received particular attention. Both the UK and EU are advancing regimes to address financial-stability risks from crypto-assets and the potential for digital finance to create new operational interconnections. Regulators discussed approaches to stablecoin oversight, tokenised assets and RegTech/suptech use cases — areas where fast technological change can swiftly outpace rulemaking. The forum provided a venue for comparing regulatory thresholds, supervisory tools and timelines for implementation. (GOV.UK)
Sustainable finance — another cross-border priority — generated debate on disclosure standards, taxonomy alignment and how to avoid greenwashing while ensuring capital flows support the net-zero transition. Both sides acknowledged differences in approach and stressed the importance of cooperative work to reduce market fragmentation and investor confusion. The statement emphasised the public-good dimension of convergent sustainable finance standards, especially where investor protection and market integrity are at stake. (Finance)
Voices from the meeting and reactions
The joint statement, published jointly by HM Treasury and the European Commission, adopted a measured tone. It stressed the value of strong dialogue to advance financial stability and market predictability without pretending to resolve political differences over sovereignty and long-term equivalence decisions. Officials described the forum as a “technical” space — deliberately kept separate from higher-order political negotiations — where supervisors and policymakers can test assumptions and exchange technical papers. (GOV.UK)
Market lawyers and industry groups welcomed the continued engagement. A number of legal and advisory firms flagged the practical benefits: clearer sightlines on EU legislative timetables reduce the risk that firms will invest in costly compliance paths that are later obsoleted by new rules. Industry sources also said the forum’s candid exchanges on securitisation and clearing had a calming effect on market expectations because both sides signalled willingness to manage risks pragmatically. However, commentators cautioned that the forum’s outputs are not a substitute for binding equivalence decisions and that some structural choices (for example, permanent relocation of euro-denominated clearing) will respond to incentives beyond regulatory dialogue alone. (Slaughter and May)
Case studies showing the forum’s practical importance
- Clearing houses and bank risk management. When the EU signalled plans earlier in 2025 to encourage greater euro-clearing capacity within the bloc, markets feared abrupt policy moves that could force large volumes of activity to relocate. The forum’s technical discussions allowed clearing houses and major banks to map contingency planning requirements with both sets of supervisors and to calibrate capital, collateral and legal restructurings sensibly — reducing the chance of rushed, market-disrupting shifts. The October meeting continued that dialogue by stressing the need for transition plans and data-sharing protocols. (Financial Times)
- Asset managers and cross-border fund servicing. Asset managers that run pan-European funds rely on interoperable frameworks for custody, reporting and investor distribution. The forum’s exchanges on asset management and fund distribution provided advance notice of regulatory changes in each jurisdiction, giving managers time to assess operational impacts and to consider strategic responses such as establishing EU-based management entities or adjusting product structures. That sort of signalling reduces transaction costs and protects investor outcomes. (GOV.UK)
- Securitisation markets and SME financing. Reform of securitisation rules matters for how banks package loans to small and medium enterprises (SMEs) and for investor demand for diversified credit exposures. The forum’s securitisation dialogue, by aligning expectations on disclosure and risk treatment, helps preserve a cross-border investor base for securitised products — supporting credit channels to the real economy. Both sides’ commitment to ongoing exchange reduces the risk of regulatory arbitrage while maintaining investor safeguards. (Finance)
Legal and political limits of the forum
Despite the technical goodwill, the forum operates within political constraints. It cannot substitute for formal equivalence regimes, and it does not change the EU’s prerogative to set rules that favour on-shore resilience. Equally, the UK retains freedom to tailor its own regulatory approach to support the City’s competitiveness. Where deeper political objectives diverge (for example, the EU’s programmatic push to build on-shore euro clearing versus the UK’s desire to retain market share in derivatives clearing), the forum can only manage consequences rather than eliminate competitive incentives. This political reality was acknowledged in Brussels: both sides politely but candidly mapped out the boundaries of co-operation. (GOV.UK)
What the forum did not do
Observers were quick to note what the meeting did not achieve. There was no attempt to negotiate new binding arrangements on equivalence or market access; there were no surprise commitments on mutual recognition of regulatory outcomes. Instead the meeting produced a joint statement recording exchanges and agreeing to keep talking. That outcome suits the forum’s remit — it is designed to reduce frictions through transparency rather than to create new legal entitlements for market participants. For firms seeking certainty on access or equivalence, the forum’s role is helpful but limited. (GOV.UK)
Forward agenda and next steps
The joint statement said the two sides would continue technical workstreams, particularly on securitisation, digital finance and sustainable finance, and that they would meet again to monitor progress. Regulators will publish further technical notes and may establish bilateral supervisory channels for specific market segments. The continuity of these dialogues is now an important part of market planning — firms and supervisors alike expect the forum to deliver early signals of change rather than sudden shocks. The European Commission’s finance division and HM Treasury will also task their respective supervisors to follow up on detailed recommendations or questions raised in the meeting. (GOV.UK)
Expert commentary and likely impact on market participants
Legal and industry analysts generally agreed the forum’s immediate impact is to reduce uncertainty. By clarifying policy timelines (for instance, the EU’s securitisation proposals) and discussing supervisory expectations, the forum enables banks, asset managers and market infrastructure providers to plan operational responses. Law firms and consultants noted that clients welcome transparency on timelines and are better able to model strategic choices such as entity reorganisation, capital management, and legal structuring when regulators signal likely directions in advance. But experts also warned that when political pressure to “on-shore” critical services increases, the forum will face limits — practical co-operation cannot indefinitely offset incentives for jurisdictions to secure domestic resilience. (Slaughter and May)
Risks and monitoring: what to watch
Policymakers and market participants should watch three things closely in the months ahead:
• The EU’s legislative timetable for securitisation and whether it contains measures that materially change the economics of cross-border securitisation; the forum will be a key place to watch re-scoping of disclosure requirements. (Finance)
• The EU and UK approaches to clearing and whether political decisions inside the EU to incentivise on-shore clearing will accelerate structural migration of activity; contingency planning and information-sharing commitments from the forum will influence how disruptive any transition would be. (Financial Times)
• How digital-asset regulation evolves, particularly for stablecoins and tokenised securities, and whether supervisory approaches create significant compliance asymmetries that push firms to choose one jurisdiction over another. (GOV.UK)
The fourth meeting of the Joint EU–UK Financial Regulatory Forum in early October 2025 reinforced the forum’s role as a technical, risk-focused channel for co-ordination on issues ranging from clearing and securitisation to digital assets and sustainable finance. Below are targeted case studies that show how the Forum’s outcomes matter in practice, short stakeholder comments that capture different perspectives, and concrete examples of mitigations and next-step actions that firms, supervisors and policymakers can use to reduce disruption. (Finance)
Case study 1 — Derivatives clearing: contingency planning avoids market shock
Problem: EU policy signals earlier in 2025 encouraged development of on-shore euro clearing capacity; market participants feared abrupt restrictions that could force large volumes of euro-clearing business to move or fall into legal uncertainty.
What happened: At the fourth Forum, EU and UK supervisors discussed clearing resilience, cross-border spillovers and data-sharing protocols. Clearing houses and major banks used these technical discussions to refine contingency plans, agree on data exchange formats and adjust their collateral and capital models in an orderly, phased way — reducing the likelihood of rushed relocations or sharp liquidity squeezes.
Why it matters: The Forum’s role in clarifying expectations and timelines allowed market infrastructures to implement operational mitigations rather than execute costly, last-minute reorganisations. (Finance)
Case study 2 — Securitisation and SME finance: preserving cross-border investor demand
Problem: Proposed changes in EU securitisation rules risked adding disclosure and risk-weighting requirements that might materially change the economics of cross-border issuance, threatening a funding channel for UK and EU SMEs.
What happened: Regulators used the Forum to exchange technical papers on the EU reform package and the UK’s parallel workstreams. Asset managers, trustees and banks were given better visibility on likely timelines and disclosure expectations; some fund managers began adjusting prospectuses and investor disclosure templates to bridge jurisdictional differences.
Why it matters: Advance signalling reduced the risk that investors would withdraw, preserving an important channel for SME credit while allowing issuers to plan legal and tax restructuring where necessary. (Finance)
Case study 3 — Asset managers and consolidated tape/T+1 coordination
Problem: Fragmented approaches to consolidated tape architecture and different T+1 implementation plans could produce mismatched settlement expectations and reporting gaps for funds operating across the UK and EU.
What happened: The Forum reaffirmed a joint interest in coordination on timing (with a growing consensus around an October 11, 2027 T+1 target) and encouraged cross-membership of industry taskforces to act as observers in each other’s design process. Several large asset managers established mirror project teams to align testing windows and reporting schemas.
Why it matters: Close technical engagement reduces operational risk and lowers the cost of dual-jurisdiction product distribution. (Finance)
Case study 4 — Digital assets and stablecoins: closer supervisory dialogue reduces compliance arbitrage
Problem: Rapid roll-out of differing crypto-asset rules (MiCA in the EU, a bespoke UK regime in development) risked prompting firms to “jurisdiction-shop” for lighter regimes or easier market access.
What happened: Supervisors compared approaches to stablecoin authorisation, custody standards and operational-resilience expectations at the Forum. The dialogue led to an agreement to share supervisory expectations and to cooperate in oversight of large cross-border crypto-asset service providers; some firms pre-emptively strengthened governance and reserve requirements to satisfy both regimes.
Why it matters: Although legal divergence remains, the supervisory convergence over key prudential and operational safeguards reduced the immediate scope for dangerous regulatory arbitrage. (Finance)
Case study 5 — Sustainable finance: disclosure alignment to prevent investor confusion
Problem: Different taxonomy shades, disclosure cadences and enforcement approaches can create greenwashing risk and deter cross-border green investment.
What happened: The Forum exchanged views on taxonomy implementation, investor disclosure expectations and the role of international bodies (ISSB, IPFS). Asset owners and advisers used the Forum’s clarifications to harmonise reporting templates and to set common due-diligence checklists for cross-border green funds.
Why it matters: Greater alignment on disclosure reduces investor uncertainty and the risk that capital flows are misdirected by inconsistent or misleading labels. (Finance)
Stakeholder comments (summarised)
- European Commission / DG FISMA: The Forum is a practical technical channel helping preserve financial stability and investor protection while respecting each side’s regulatory autonomy. (Finance)
- HM Treasury: The Forum provides predictability for markets and a platform for contingency planning on shared risks such as clearing and digital finance. (GOV.UK)
- Industry groups (banks, asset managers): Welcome the early signalling and taskforce observer arrangements — but stress that the Forum cannot replace formal market-access or equivalence decisions.
- Market lawyers / consultants: Value the Forum’s joint statements as crucial inputs into firms’ restructuring models, but warn that political incentives (e.g., on-shoring critical services) can still drive outcomes beyond technical co-operation. (Slaughter and May)
Practical examples of mitigations and next steps
- Joint contingency playbooks for clearing: Supervisors should develop interoperable contingency frameworks (data sharing, recovery triggers, liquidity backstops) and publish high-level playbooks that allow CCPs and banks to synchronise plans. (Already discussed in Forum dialogues.) (Finance)
- Cross-membership of industry taskforces: Invite industry taskforces (consolidated tape, T+1, crypto) to add observer seats for the counterparty’s taskforce so technical design choices are visible early — this lowers operational mismatch risk. (Finance)
- Regulatory “interoperability” pilots: For tokenised assets and digital-settlement rails, run time-limited pilots with joint supervisory oversight to test KYC, custody and settlement assumptions across jurisdictions before full market launches. (Finance)
- Common disclosure templates for securitisation and sustainable funds: Regulators can encourage (or publish) harmonised disclosure checklists for cross-border issuances and ESG funds so that originators and managers follow a single playbook for investor reporting. (Finance)
- Information-sharing MoUs between supervisory colleges: Where firms operate critical infrastructures in both jurisdictions, supervisors should sign MoUs that specify timelines for data requests, crisis communications and joint inspections — reducing delay in stress situations. (Finance)
Risks and limits — what the Forum cannot do
- The Forum cannot create binding equivalence or market-access rights; major structural incentives (such as political efforts to on-shore euro clearing) will still drive commercial relocations. (Regulation Tomorrow)
- Technical co-ordination reduces but does not eliminate the cost of dual compliance; smaller firms may still face hard choices about where to base certain activities.
- The Forum’s effectiveness depends on political will: if either side makes abrupt policy choices for domestic reasons, technical dialogue alone may not prevent market fragmentation. (Finance)
What to watch next
- Follow-through technical notes from HM Treasury and the European Commission (the Forum signalled a programme of follow-up papers). Stakeholders should read those closely for timelines and supervisory expectations. (GOV.UK)
- EU securitisation legislation and any consequential amendments that materially change risk weights or disclosure — these would most affect cross-border SME funding. (Finance)
- Progress on T+1 and consolidated tape design — misalignment here would generate operational and cost pressures for cross-border funds. (Finance)
Short conclusion
The fourth Forum demonstrated pragmatic, technical co-operation delivering value through early signalling, contingency planning and supervisory dialogue. Its concrete effect is to buy time and clarity for market participants while preserving options for national regulatory autonomy. For firms, the guiding principle is clear: incorporate Forum outputs into operational roadmaps now — and be prepared for political decisions that may re-shape incentives later. (Finance)
