Swiss banks face numerous regulatory challenges in areas like tax transparency, anti-money laundering (AML), and information exchange as international standards evolve. Banks must enhance client data quality and onboarding processes to comply with new regulations like the OECD's Automatic Exchange of Information (AEI) beginning in 2017. This will require significant changes to due diligence procedures for new and pre-existing individual and entity accounts. Financial institutions must also coordinate multiple reporting lines under different standards to avoid duplicate or inconsistent reporting. Overall, banks need to prioritize projects to ensure systems and data are ready for new regulations affecting countries that have adopted early adoption of the AEI and OECD Common Reporting Standard.
