The risk of loss is caused by an inadvertent or negligent failure to meet a professional (legal) commitment to a specific customer (including fiduciary and appropriateness standards) or by the nature or design of a product. It is a recognised risk category in regulatory frameworks worldwide (Basel II/III standards), usually called Customer, Products and Business Practices.
In addition, banks can suffer administrative or criminal penalties imposed by the government. A court case involving a bank may have graver implications for the institution than just the legal costs. Banks cannot effectively protect themselves from such legal risks if they do not practice due diligence in identifying customers and understanding and managing their exposure to money laundering.
