KYB and KYC are moving beyond one-off onboarding towards ongoing, evidence-based assessment of customer risk, but the regulatory position is not equally settled across the three key markets. The EU has a fixed implementation date for its single rulebook, the UK is progressing through a staged implementation programme, and the US framework remains in active reform. In the UK, under the Economic Crime and Corporate Transparency Act 2023, Companies House identity verification became mandatory from 18 November 2025 for new company directors, LLP members and persons with significant control. Existing directors, LLP members and PSCs are being brought into scope during a 12-month transition ending in November 2026. Directors generally provide their verification credentials with the company’s next confirmation statement, while PSCs must comply by the individual deadline shown by Companies House. Companies House estimates six to seven million existing directors and PSCs are in scope during the transition. Compulsory identity verification for people presenting filings, and the requirement for third-party filers to be registered as Authorised Corporate Service Providers, are now scheduled for no earlier than November 2026. Separately, the failure to prevent fraud offence came into force on 1 September 2025. It applies to organisations meeting at least two of three criteria: more than 250 employees, turnover above £36 million or total assets above £18 million. An organisation may face an unlimited fine where an associated person commits fraud intending to benefit the organisation or its clients, unless the organisation can demonstrate that it had reasonable fraud-prevention procedures in place. Official guidance identifies proportionate due diligence as one component of those procedures. The core UK AML framework remains the Money Laundering Regulations 2017, as amended most recently by the Money Laundering and Terrorist Financing (Amendment) Regulations 2026, which came into force on 30 June 2026, together with the Proceeds of Crime Act 2002 and the Sanctions and Anti-Money Laundering Act 2018. JMLSG guidance and the FCA Financial Crime Guide inform how firms are expected to implement those legal and regulatory obligations but are not themselves primary legislation. In the EU, the Anti-Money Laundering Regulation, Regulation (EU) 2024/1624, will apply directly in Member States from 10 July 2027, substantially harmonising the obligations imposed on regulated firms. Directive (EU) 2024/1640 is being transposed in phases, with the principal deadline also falling on 10 July 2027, while retaining national provisions for supervision, financial intelligence units and beneficial ownership registers. The Anti-Money Laundering Authority has operated from Frankfurt since 1 July 2025. It will select its first cohort of 40 high-risk cross-border financial institutions during 2027 and begin their direct supervision in 2028. For specified serious, repeated or systematic breaches by directly supervised institutions, AMLA’s sanctions can reach 10% of the institution’s total annual turnover in the preceding business year. The general EU beneficial ownership threshold will be direct or indirect ownership of 25% or more, but that percentage is not a safe harbour: control through other means must also be assessed. By 10 July 2029, the Commission must assess whether specified categories of higher-risk corporate entities should be subject to lower ownership thresholds. For those categories, the threshold will ordinarily be set at no more than 15%, although the Commission may choose a higher threshold below 25% where that is more proportionate to the risk. In the US, the framework remains the Bank Secrecy Act and its implementing regulations in 31 CFR Chapter X. For covered financial institutions and in-scope legal entity customers, the applicable Customer Identification Program requirements and FinCEN Customer Due Diligence Rule require the identification and verification of each individual owning 25% or more of the entity, together with one individual exercising significant responsibility to control, manage or direct it. FinCEN granted important relief in February 2026: institutions no longer need to identify and verify the same legal entity customer’s beneficial owners every time it opens another account. The exercise is now required when the customer first opens an account, when information arises that calls the previous beneficial ownership information into question, or when required under the institution’s risk-based ongoing due diligence procedures. The Corporate Transparency Act position has also narrowed sharply. FinCEN’s March 2025 interim final rule remains the operative position and exempts entities created in the United States, their beneficial owners and US persons from federal beneficial ownership reporting. Reporting is now confined principally to qualifying foreign entities registered to do business in a US state or Tribal jurisdiction. Domestic companies are therefore not required to populate or maintain a current federal BOI filing, meaning that financial institutions cannot rely on a comprehensive federal register for domestic entities and remain responsible for gathering and evaluating beneficial ownership information through their own CDD and risk-based procedures. Despite these different legal architectures, the common supervisory expectation is clear. Firms must understand complex and cross-border ownership structures, identify actual control rather than stop mechanically at percentage thresholds, screen the relevant connected parties, and retain evidence showing how the available facts, risk context and applicable policy produced the outcome. A scalable operating model combines AI-supported due diligence with accountable human oversight, event-driven monitoring rather than calendar-only review, back-book remediation, and policy-driven automation that preserves source evidence and an auditable reasoning trail. CleverChain is built for this model, applying policy-native assessment to the framework governing each customer rather than forcing every case through a single generic standard.
