The Financial Services and Markets Bill, introduced on 19 May 2026, has been read in most commentary as a tidy package of Leeds Reforms commitments. We think that framing materially understates what is happening. The Bill is the political anchor for a much larger reset of UK capital markets regulation that lands across 2026 and 2027, and capital markets firms approaching it as a discrete compliance project are already a step behind.

The Bill is important, but it should be viewed in the context of a broader regulatory programme that will affect capital markets firms throughout 2026 and 2027.

What does the Financial Services and Markets Bill mean for capital markets firms?

While the Bill itself contains several important reforms, the broader challenge for firms is the cumulative impact of multiple regulatory initiatives landing over the next two years. These include changes to transaction reporting, EMIR, short selling, securitisation, SM&CR and T+1 settlement.

 

Key capital markets reforms landing in 2026–27

Read in isolation, the Bill is a thinner document for capital markets firms than for retail-facing peers. Read alongside the parallel workstreams set out in the May 2026 Regulatory Initiatives Grid, the picture changes. The same firms will be implementing many of the following reforms within a relatively compressed timeframe:

  •  MiFIR transaction reporting transfer to the FCA Handbook, with policy development expected during H2 2026 and downstream system and reporting changes likely to follow.
  • Transaction and post-trade reporting harmonisation work across MiFIR, EMIR and SFTR, expected to progress through 2026–27.
  • UK EMIR Title II repeal and replace covering OTC derivatives, with detailed firm-facing requirements moving into regulator rulebooks.
  • Wholesale Markets Review reforms covering the equity consolidated tape, market structure and transparency.
  • New UK Short Selling Regulation requirements coming into force during 2026, with further technical implementation measures following thereafter.
  • Securitisation framework reforms expected to continue through late 2026 and into 2027.
  • T+1 settlement implementation ahead of the UK go-live date of 11 October 2027.
  • SM&CR Phase 2 consultations following the Bill’s proposals to move elements of the regime away from primary legislation and into regulator rulebooks.

Layered on top, the Bill’s new overseas recognition framework begins to reshape the legal basis on which firms rely on third-country venues, CCPs and counterparties. None of these developments are catastrophic individually.

Taken together, they may represent the most significant cumulative implementation profile UK capital markets firms have faced since MiFID II.

 

Where firms are getting it wrong

Our work with clients across the sector points to three patterns that repeatedly emerge when change of this scale lands on a wholesale firm.

  • Pitfall 1 – Managing reform through isolated workstreams: Workstream silos dominate. Transaction reporting sits with one team, EMIR with another, SM&CR with HR-adjacent compliance, T+1 with operations, and overseas recognition with legal. The cumulative business case never gets built, and individual workstreams are funded as if they were independent. By 2027, firms can find themselves dealing with overlapping system changes, duplicated supplier spend and gaps at the seams.
  • Pitfall 2 – Treating the Bill as primarily domestic: The overseas recognition framework may prove to be the Bill’s most strategically consequential provision for capital markets firms. Many firms we speak with have not yet completed a comprehensive inventory of the cross-border arrangements that depend on existing equivalence determinations, from overseas CCP reliance through to delegation and branch operations. By the time the framework begins to replace specific equivalence regimes, the cost of remediation may be significantly higher than the cost of preparing early.
  • Pitfall 3 – Treating SM&CR Phase 2 as a simplification exercise: Proposals to remove or substantially reform elements of the Certification Regime and rewrite aspects of the framework within regulator rulebooks will not be cost-free. Firms with large, certified populations on trading floors and in structuring teams should budget for a meaningful transition exercise, governance documentation refreshes, control framework updates and a careful review of FCA and PRA consultations to ensure the future-state regime is engineered rather than simply inherited.

 

Practical steps firms should take now

We help clients respond to change of this scale by building an integrated view of regulatory change from the outset. In practice, that means focusing on four key areas.

  • Build a single implementation map: Develop a consolidated 2026–27 implementation plan that overlays the Financial Services and Markets Bill, parallel wholesale market reforms, and the firm’s existing change portfolio. The objective is to identify dependencies, sequencing risks, and areas of duplicated spend before they become embedded in delivery programmes.
  • Review cross-border dependencies: Create a comprehensive inventory of cross-border arrangements that currently rely on equivalence determinations, including overseas CCP access, delegation models, branch structures, and third-country market infrastructure. Firms should also assess how these arrangements may be affected as HM Treasury begins to exercise its new recognition powers.
  • Assess SM&CR Phase 2 readiness: Undertake an early assessment of the potential impact of SM&CR Phase 2 reforms, including implications for certified populations, Statements of Responsibility, governance frameworks, and existing control structures. This will help firms respond more effectively as FCA and PRA consultations emerge.
  • Engage early with consultations: Develop a structured consultation engagement plan for H2 2026 and beyond. Many of the practical compliance obligations will ultimately be determined through regulator rulemaking, making early engagement critical for firms seeking to influence implementation outcomes and prepare effectively for future requirements.

 

The strategic opportunity

The Bill is being presented by the Government as a growth and competitiveness measure, and there is substance behind that framing. The combination of overseas recognition, shorter regulator determination periods, a provisional licences regime and greater proportionality within the SM&CR framework has the potential to make the UK a more agile jurisdiction for capital markets activity.

Firms that build the integrated implementation view described above often end up doing more than simply absorbing change. They position themselves to use the evolving framework deliberately, whether through faster senior hiring, new product permissions, restructured group arrangements or expanded cross-border activity.

That, in our experience, is the difference between firms that emerge from a multi-year reform cycle as compliant survivors and firms that emerge with strategic ground gained.

fscom partners with capital markets firms through reform cycles of exactly this shape. We bring an integrated change lens across prudential, conduct and market structure workstreams; deep familiarity with SM&CR transitions, transaction reporting reviews and cross-border equivalence mapping; and a senior team that has sat on both sides of regulator engagement.

If your firm is assessing the impact of the Financial Services and Markets Bill, preparing for SM&CR Phase 2, or building a broader capital markets change programme, fscom can help you identify dependencies, prioritise implementation activity, and engage effectively with regulatory change.
