What are the implications of GwG 21 for financial intermediaries?

The revised Anti-Money Laundering Act (GwG 21) came into force on 01 January 2023. This is Switzerland’s response to a report by the Financial Action Task Force (FATF), which identified weaknesses in Switzerland’s fight against money laundering and terrorist financing. The GwG 21 revision entails tighter due diligence requirements and involves measures in the areas of beneficial ownership, actuality of client data and money laundering suspicious activity reporting.

What does this mean for financial institutions? They now face the challenge of implementing the regulatory requirements as quickly as possible and coping with the additional administrative work that this entails. Failing to comply with the obligations may result in reminders and sanctions from the Financial Market Authority (Finma).

Most important changes at a glance

Now, the identity of the beneficial owner must be verified instead of just stated.

Financial intermediaries must now carry out a periodic review of customer information irrespective of events. The extent and regularity of this review is to be decided on a risk basis.

GwG 21 confronts financial intermediaries with administrative challenges

It is all about KYC

Banks now have to know and document their clients by means of conclusive KYC data (Know Your Customer). On one hand, this refers to simple customer data such as name and address, but also information on the origin of the assets as well as the beneficial ownership and the purpose of the business relationship.
The financial intermediaries are obliged to check and update this KYC data regularly, irrespective of events. The periodicity and depth of the audit depends on the respective risk profile of the customer, whereby the determination of this risk has not been regulated by law and is the responsibility of the banks. Thus, for low-risk business relationships, customer details and supporting documents need to be reviewed and updated less frequently than for high-risk ones. However, depending on the risk profile, the data update may even be required on an annual basis.
