OPBAS Flags Persistent AML Enforcement Weaknesses Ahead of FCA Takeover

The Office for Professional Body Anti-Money Laundering Supervision (OPBAS) has published its latest review into how professional body supervisors oversee the legal and accountancy sectors, pointing to measurable improvements since its establishment in 2018 while warning that deep-rooted weaknesses in enforcement remain unresolved. Although supervisory standards have generally improved over the past several years, the regulator continues to express concern about inconsistent disciplinary action and uneven deterrence across the industry. The findings arrive at a pivotal moment, as the government prepares to transfer anti-money laundering supervision of these sectors to the Financial Conduct Authority in a sweeping reform designed to strengthen the country’s defenses against illicit financial flows.

The latest review focused squarely on whether professional body supervisors are effectively holding their members accountable for anti-money laundering failures. While compliance rates have broadly trended upward, OPBAS found that enforcement remains a significant weak spot. Many supervisory bodies continue to struggle with the inherent tension of serving both as representative membership organizations and as regulatory enforcers. This structural conflict, the report suggests, can lead to a softer disciplinary stance that fails to create a meaningful deterrent for firms tempted to neglect their reporting and due diligence responsibilities. Without the credible threat of substantial financial penalties or public censure, smaller firms in particular may see little incentive to invest in robust compliance systems.

The review underscores that the legal and accountancy professions are especially vulnerable to exploitation by sophisticated money laundering networks. As gatekeepers to the financial system, lawyers and accountants can provide an aura of legitimacy that allows illicit funds to flow into the mainstream economy. When supervisors do not rigorously police these gatekeepers, the broader national effort to combat organized crime and terrorist financing is weakened. OPBAS found instances where supervisory bodies lacked clearly defined criteria for identifying serious breaches, resulting in inconsistent outcomes where comparable failures led to sharply divergent disciplinary responses. Such unpredictability, the regulator warned, blurs the boundaries of acceptable conduct and enables bad actors to gravitate toward the weakest supervisory links.

The report also identifies shortcomings in how supervisors harness intelligence and data. Effective oversight, OPBAS argues, must be proactive and grounded in risk-based assessments rather than reactive responses to scandals or complaints. Some bodies were found to be relying on outdated risk assessment methodologies that may overlook emerging patterns in financial crime. As the use of digital assets and increasingly complex corporate structures becomes more prevalent, supervisory frameworks must adapt accordingly. Although OPBAS has urged supervisors to adopt more advanced monitoring tools, progress has been uneven. This lag in technological modernization leaves vulnerabilities that can be exploited by criminals seeking to channel illicit funds through legitimate-appearing transactions.

In light of these persistent weaknesses, the government confirmed in 2025 that responsibility for anti-money laundering and counter-terrorist financing supervision in the legal and accountancy sectors will shift to the Financial Conduct Authority. The reform marks a fundamental change in the UK’s approach to safeguarding its professional services industry from criminal misuse. By replacing a fragmented system of 25 separate professional body supervisors with a single, well-resourced regulator, policymakers aim to deliver greater consistency, eliminate conflicts of interest, and strengthen enforcement. Centralizing authority within the FCA is intended to ensure that disciplinary decisions are handled by an institution experienced in high-stakes regulation.

The move toward consolidation is also expected to reduce regulatory complexity for firms operating across multiple practice areas or jurisdictions. Under the existing regime, firms may answer to several supervisors, each applying slightly different interpretations of anti-money laundering rules. This patchwork system increases administrative burdens without necessarily improving outcomes. A unified supervisor, by contrast, can offer clearer guidance, standardized reporting channels, and a single focal point for intelligence sharing. Given the speed at which international money laundering networks adapt, policymakers argue that a cohesive regulatory response is essential to keep pace.

During the transition period, OPBAS has indicated it will deploy its full suite of powers to accelerate improvements. For the first time, this includes the potential use of direct enforcement action against supervisors who fail to meet their statutory obligations, alongside formal directions aimed at driving compliance. The message to professional bodies is unmistakable: light-touch oversight is no longer acceptable. Supervisors are being pressed to strengthen their enforcement capabilities and demonstrate a willingness to impose meaningful sanctions, even when doing so affects their own members.

A central theme of the report is the need to enhance both the severity and visibility of penalties. For anti-money laundering frameworks to function effectively, the financial and reputational consequences of non-compliance must outweigh the cost of implementing adequate controls. Historically, some fines have been viewed by larger firms as little more than operational expenses. OPBAS is now advocating for penalties calibrated to the size of the firm and the systemic risk created by its failures. This includes not only higher fines but also more frequent publication of disciplinary outcomes, using naming-and-shaming measures to impose reputational consequences that extend beyond monetary sanctions.

At the same time, the report stresses that enforcement must be paired with improved guidance and training. Many professionals do not intentionally facilitate crime but may become entangled due to weak internal controls or limited awareness of evolving risks. Supervisors are encouraged to disseminate real-world case studies and typologies illustrating how money laundering schemes manifest within legal and accountancy practices. Strengthening knowledge at the practitioner level, the report argues, can create a more resilient first line of defense against criminal infiltration.

A more integrated supervisory framework is also expected to enhance cooperation with law enforcement, including agencies such as the National Crime Agency. Suspicious activity reports filed by lawyers and accountants often provide the foundation for major investigations. Inconsistent supervision can lead to variable report quality, diverting valuable law enforcement resources. A standardized regime, OPBAS suggests, would improve the consistency and usefulness of financial intelligence, increasing the likelihood of successful prosecutions and asset recovery.

Looking ahead, the reforms signal a lasting shift in how the UK views the role of professional services in combating financial crime. Compliance will be judged not by the presence of written policies alone, but by their practical effectiveness in identifying and mitigating genuine risks. As the transition to the FCA progresses, firms should anticipate more frequent on-site inspections, closer scrutiny of client due diligence files, and far less tolerance for administrative shortcomings. The threshold for what qualifies as an adequate compliance program is rising across the board.

While the adjustment may prove demanding for some organizations, policymakers believe the long-term benefits will outweigh the short-term challenges. A professional services sector that operates within a more rigorous and transparent regulatory framework is likely to enhance the UK’s global reputation as a clean and trustworthy business environment. OPBAS has made clear that it will continue to monitor developments closely to ensure that every supervisor—current and future—contributes to protecting the integrity of the financial system from the corrosive effects of money laundering.
