HM Treasury's MLRs reform response

A strategic pivot towards proportionality and precision in AML regulation

What’s this about?

In a significant move to recalibrate the UK’s anti-money laundering (AML) framework, HM Treasury has published its response to the 2024 consultation on improving the effectiveness of the Money Laundering Regulations 2017 (MLRs). The response signals a clear intent to streamline compliance, reduce regulatory friction, and enhance the UK’s resilience to economic crime.

Our Head of Risk and Financial Crime, Ben Cooper says...

“The Treasury’s response is a welcome step towards a more intelligent AML regime—one that balances the UK’s global leadership in financial services with its commitment to tackling illicit finance. As always, the devil will be in the detail, and firms should prepare for further guidance and secondary legislation in the months ahead.”

1. Customer due diligence: Towards a more nuanced risk-based approach

The Treasury’s response acknowledges widespread concerns that the current CDD framework is overly prescriptive and often misaligned with actual risk. The government proposes:

  • Clarified thresholds for Simplified Due Diligence (SDD): Firms will benefit from clearer guidance on when SDD is appropriate, particularly in low-risk scenarios such as pooled accounts.
  • Refined triggers for Enhanced Due Diligence (EDD): The response seeks to better align EDD obligations with genuine risk indicators, reducing unnecessary burdens on firms dealing with low-risk customers. The Treasury intends to make changes to the EDD on complex transactions and high-risk third countries.
  • Improved guidance on ongoing monitoring: The Treasury commits to working with supervisors to ensure firms can adopt a proportionate approach to transaction monitoring, particularly for long-standing, low-risk relationships.

This shift reflects a broader policy trend: empowering firms to exercise professional judgment within a clearer regulatory perimeter.

2. Strengthening system coordination: A more cohesive supervisory landscape

The consultation response recognises that fragmentation across the UK’s AML supervisory regime has led to inconsistent enforcement and inefficiencies. Key proposals include:

  • Enhanced role for OPBAS: The Office for Professional Body AML Supervision will be given a more strategic mandate to drive consistency and raise supervisory standards.
  • Improved data sharing: The government will explore legislative and technical solutions to facilitate better information exchange between supervisors, law enforcement, and regulated entities.
  • Alignment with the National Risk Assessment (NRA): Supervisors will be expected to prioritise resources in line with the NRA, ensuring a more intelligence-led approach to supervision.

These reforms aim to create a more coherent and responsive AML ecosystem, capable of adapting to evolving threats.

3. Clarifying scope and registration: Addressing ambiguities and emerging risks

The response addresses several grey areas in the current MLRs, particularly around the scope of regulated activities and registration obligations:

  • Cryptoasset service providers: The government proposes a clearer definition of what constitutes a change in control, triggering re-registration requirements.
  • Trust or Company Service Providers: New rules will target the resale of “off-the-shelf” companies, a known vulnerability in the UK’s corporate transparency regime.
  • Currency thresholds: The Treasury is considering adjustments to the cash transaction thresholds that trigger AML obligations, to reflect inflation and evolving risk profiles.

These changes are designed to close loopholes without imposing unnecessary burdens on legitimate businesses.

4. Smarter regulation in practice

Echoing the government’s broader deregulatory agenda, the response emphasises the need for a risk-based, proportionate approach that supports innovation and competitiveness without compromising on financial integrity.

What this means for regulated firms

For financial services firms, the direction of travel is clear: expect a more nuanced regulatory environment that rewards effective risk management over box-ticking compliance. However, firms will need to stay agile as the government moves from consultation to implementation, particularly in areas like crypto regulation and trust registration.
