Understanding financial regulation and enforcement trends in 2026 makes predicting the weather look straightforward.
While much has been made of the trend towards deregulation and dampened enforcement activity, this is unlikely to translate into more certainty and less complexity for financial organizations in the year ahead. In fact, many will be tested by risk factors outside their control and growing accountability.
We forecast a pivotal year for investigations and enforcement, with pressure building on three fronts — politics, people and technology.
UK payment services regulation: at a crossroads
HM Treasury’s consultation signals the UK’s post-Brexit direction for modernising payment services regulation as it diverges from the EU’s PSD3 framework.
The Mills Review revisited: where autonomous AI is testing the UK regulatory framework
The FCA’s position has been that the UK’s existing regulatory framework can accommodate AI and that AI-specific regulation is not currently required. The Mills Review (the “Review”), published by the FCA on 6 July 2026, broadly supports that view. It should not, however, be read as signalling regulatory restraint. Rather than proposing new rules, it anticipates heightened expectations around governance, oversight and evidencing compliance as firms adopt increasingly autonomous AI systems.
Financial Ombudsman Service reform
The Financial Ombudsman Service's (FOS) policy statement on Modernising the Redress System (Policy Statement), published on 11 August 2026, is the latest development in the evolution of UK financial services redress. Viewed in isolation, the reforms are significant: the FOS will proceed with the development of a registration framework, dismissal powers will be expanded, and DISP 3.6.4R of the FCA's Dispute Resolution: Complaints sourcebook (DISP) will be amended to clarify that complaints are to be determined against the standards that applied at the time of the relevant conduct.
