Switzerland's Federal Department of Finance will submit a report to the Federal Council by the end of 2027 on how to optimise Swiss financial market regulation. The review will cover both financial market rules and the supervisory framework, with the stated aim of reducing administrative burden and removing duplications while maintaining stability, integrity, client protection, well-functioning markets and competitiveness. To support the work, the department has created an external working group led by Monica Mächler, a financial market law expert and former vice chair of FINMA. Other members are Rashid Bahar, Mirjam Eggen, Reto Föllmi and Hans Kuhn. The review is framed as part of broader international efforts to modernise financial market regulation, including discussions in bodies such as the Financial Stability Board. It does not cover banking stability measures currently being discussed in Parliament or planned by the Federal Council. After a preparatory phase, the working group will consult the relevant sectors and authorities and deliver its analysis and recommendations to the department. Those findings will feed into the department's report to the Federal Council, together with recommendations for follow-up work, by the end of 2027.
