This publication explores novel types of financial sanctions against Russia, specifically the prohibitions on accepting deposits and the sale of securities, that have been adopted in Switzerland and the EU since 2022. The paper provides context, outlines the legal basis for the adoption and implementation of the sanctions, and compares the new Swiss restrictions with the relevant EU regulations. The author scrutinized the text of the Swiss ordinance, related EU decisions and regulations, as well as guidance documents published by the competent authorities of Switzerland, the EU and various EU member states. The research highlights differences in legal vocabulary and scope, gives an overview of varying exemptions across jurisdictions, showing complexity and risks associated with non-compliance with the evolving regulations.
