Regulatory compliance is entering its most significant period of transformation in decades. The objective - complying with the law - hasn't changed, but the environment has: supervisory expectations are expanding, regulatory change is accelerating, and Boards now expect compliance functions to explain risk and support decisions, not simply document adherence.

This is changing what Regulatory Mapping is for. It has long served to identify applicable regulations and demonstrate coverage - useful but limited. Leading institutions now use it to connect obligations to the policies, processes, risks, controls, and governance forums they influence, turning regulatory information into an enterprise asset rather than static documentation.

On 19 February 2026, the Prudential Regulation Authority (PRA) published Consultation Paper CP3/26, setting out proposed amendments to the PRA Rulebook to reflect the implementation of HM Treasury's (HMT) Overseas Prudential Requirements Regime (OPRR). Following consultation, the PRA published Policy Statement PS16/26 on 14 July 2026, confirming its final rules.

Artificial intelligence, increasingly sophisticated criminal networks, expanding sanctions regimes, beneficial ownership transparency, geopolitical instability, and heightened regulatory expectations are reshaping how institutions identify, assess, and manage financial crime risk.

Anti-Money Laundering (AML) has entered one of the most significant periods of transformation since the introduction of modern AML legislation more than two decades ago. The objective of preventing money laundering and terrorist financing remains unchanged, but the environment in which financial institutions operate has evolved dramatically.

In May 2026, the Bank of England issued a range of publications, setting out its approaches and expectations on several areas with heightened regulatory focus, covering banking supervision, operational resilience, cybersecurity risk and tokenised assets.

Geopolitical risk is no longer just a “watch-list” issue. It is becoming a core risk management expectation for banks. While supervisors and industry bodies have not prescribed a single framework, the direction of travel is clear: banks are increasingly expected to show how geopolitical risk is identified, assessed, governed, stress-tested and translated into risk appetite, strategy and business decisions. This article digs deeper into the topic.

The PRA has published Policy Statement 15/26, concluding the first phase of a two-stage review of its Pillar 2A methodologies and supporting guidance. This article summarises the impact for firms.

Regulatory reporting has traditionally been viewed by banks as a necessary but resource-intensive compliance exercise. However, with the introduction of Basel 3.1 and the UK’s Simplified Capital Regime, firms are now presented with a timely opportunity to re-think their approach. Rather than treating regulatory change as a constraint, firms can instead use it as a catalyst for a broader transformation that drives improvements in governance, data quality, systems, and overall operational efficiency.

On 17 April 2026, the PRA published its Business Plan for the 2026/27 financial year, which sets out the PRA’s strategic priorities and confirms its continued focus on safety and soundness and policyholder protection, alongside a proportionate and efficient approach to regulation. Over the year ahead, the PRA will continue to embed key reforms, including the implementation of Basel 3.1, the Strong and Simple framework for smaller banks (SDDTs), and enhancements to operational resilience.

The PRA published three coordinated policy statements on 26 March 2026 (PS9/26, PS10/26, PS11/26), recalibrating the UK's resolution and recovery framework. For small and mid-tier banks, the changes bring tangible benefits, but the bar for preparedness is not falling. We summarise what's changing, what it means, and what firms should do now.

The PRA’s latest consultation (CP5/26) marks a notable evolution in the UK liquidity framework.

Rather than increasing quantitative requirements, focus is shifting toward liquidity usability and operational readiness, reflecting lessons from recent market events and the accelerating impact of digital banking on deposit behaviour.

Katalysys had convened a consortium of non-systemic banks to jointly develop a credible, practical, and proportionate framework for climate-related financial risk assessment.
