FinSA (FIDLEG): rules of conduct, client segmentation and the adviser register

The Swiss Financial Services Act (FinSA, in German FIDLEG) sets out how financial service providers in Switzerland classify, inform and advise their clients and how they document the advice; it also governs the client adviser register, prospectuses and key information documents. Peak Compliance brings together the key provisions and articles for portfolio managers here and applies the duties in practice through compliance outsourcing and the client adviser register training.

  3. Disclose the service, risks and costs clearly; handle third-party compensation transparently.
  4. Document the mandate and the advice and report to clients regularly.
  5. Train client advisers and, where required, register them in the client adviser register.

Frequently asked questions

Who does FinSA apply to?

FinSA applies to financial service providers that provide financial services in Switzerland, such as portfolio management or investment advice, and to their client advisers. It also covers producers and providers of financial instruments. Portfolio managers licensed under FinIA apply the FinSA rules of conduct in their daily work.

Which client segments does FinSA define?

Art. 4 FinSA distinguishes retail, professional and institutional clients. The segment determines the scope of the information, appropriateness and documentation duties. Providers that treat all clients as retail clients may dispense with segmentation.

Which rules of conduct matter most in practice?

The core duties are information (Art. 8 FinSA), the appropriateness and suitability assessment (Art. 10 et seq. FinSA), documentation and accountability (Art. 15 and 16 FinSA) and the handling of third-party compensation (Art. 26 FinSA). Peak Compliance embeds these duties in directives, processes and controls.

What does FinSA require of client advisers?

Client advisers must know the rules of conduct and have the necessary expertise (Art. 6 FinSA). Where the duty to register applies, they register in a client adviser register (Art. 28 FinSA) and renew the entry no later than every 24 months. Peak Compliance offers the basic training and refresher online.
