When the FATF Force first began combatting money laundering, the best practice at the time was to prescribe a fixed set of rules to deal with specific situations. They later realised that this sort of narrow-mindedness was irrational and substituted the rules-based approach with the risk-based approach to the issue of client identification and verification.
A core principle of the risk-based approach is that Accountable Institutions’ treatment of their clients must vary according to each client’s risk profile.
