Ten years after Brexit, a Reuters analysis finds London's financial industry has broadly recovered but faces structural constraints on further growth
A Reuters long-read published on 21 June — timed to the tenth anniversary of the Brexit referendum — assesses how London's financial sector has rebuilt following the UK's departure from the European Union single market. The piece finds that while the most catastrophic predictions (immediate recession, housing crash) did not materialise, the structural drag on the UK economy has been real: economists broadly estimate the UK's GDP is 2–8% smaller than it would otherwise have been. For financial services specifically, the article and corroborating coverage from CNN, the FT, AP and the San Francisco Chronicle all converge on the same theme: businesses have adapted but at material cost, with trade friction, regulatory divergence, and the end of financial services passporting all forcing structural change. The Office for Budget Responsibility has estimated a long-term 4% productivity shortfall attributable to Brexit, equivalent to over £100 billion in lost national income annually. On trade, UK-EU bilateral trade was worth £856 billion last year, dwarfing the value of any post-Brexit free trade deals signed with third countries. The failure to secure mutual recognition of professional qualifications has created ongoing barriers for law and financial services practitioners seeking to work across borders. A majority of Britons — around six in ten in a YouGov poll — now consider Brexit to have been a failure, and a separate ECFR poll cited by Reuters found a majority are disappointed with the outcome. The Labour government's EU 'reset' — including Horizon Europe rejoining — is ongoing but constrained by political and sovereign trade-offs.
Why this matters
For City law students, the Brexit decade story is directly relevant to capital markets practice: the loss of financial services passporting (which allowed UK-authorised firms to offer services across EU member states without separate authorisation) fundamentally reshaped where deals are structured and which regulators have jurisdiction. Many international firms responded by establishing or expanding EU hubs in Paris, Frankfurt, Dublin and Amsterdam, creating parallel regulatory compliance requirements. The ongoing question of equivalence decisions — whether the FCA and PRA are treated as equivalent regulators under EU law — continues to affect cross-border capital markets access. The current UK-EU reset creates new advisory demand around trade compliance, regulatory divergence analysis, and professional qualification recognition, areas where City firms with both UK and EU practices are well-placed. No specific named advisers are mentioned in the source material.
On the Ground
A trainee working on a post-Brexit regulatory compliance matter would be drafting compliance gap analysis memos comparing UK and EU regulatory requirements, preparing regulatory notification drafts for firms seeking dual authorisation in London and an EU financial centre, and summarising licence condition changes resulting from divergence between FCA and equivalent EU rules.
Interview prep
Soundbite
Lost passporting rights still force dual-authorisation structures on every UK firm accessing EU capital markets — that complexity is permanent client work.
Question you might get
“How did the loss of financial services passporting change the way UK-based investment banks structure their European operations, and what does that mean for legal advisory work?”
Full answer
Ten years on from the Brexit referendum, corroborated analysis from Reuters, CNN and AP confirms the UK economy is measurably smaller than it would have been, with the OBR estimating a permanent 4% productivity gap. For capital markets practice, the practical legacy is the end of financial services passporting — UK-authorised firms can no longer automatically offer services across the EU, forcing either dual-authorisation or EU-hub structures. This has generated sustained advisory demand in regulatory compliance, equivalence monitoring, and cross-border deal structuring. The Labour government's EU reset adds a new layer: any extension of regulatory alignment (for example on financial services equivalence) would reshape the competitive landscape for London as a listing and deal venue. This suggests the regulatory advisory pipeline from Brexit-related divergence management will persist for years, regardless of the overall political direction of travel.
