Meeting the Highest Standards

Transparency and equal treatment are the cornerstones of a regulated market like the Swiss Stock Exchange. We are subject to the direct supervision of FINMA, the Swiss Financial Market Supervisory Authority, and to the Swiss Financial Market Infrastructure Act (FMIA), and we hold 6 of only 7 authorizations for Swiss financial market infrastructures granted by FINMA. The Swiss National Bank monitors the systemically important infrastructure of SIX (such as SIC, SECOM and the central counterparty SIX x-clear).  

Trading Rules

The Trading Rules govern the rights and obligations of the Swiss Stock Exchange and its participants and traders. It is based on the principles of the Swiss Federal Act on Financial Market Infrastructures and Market Conduct in Securities and Derivatives Trading (FMIA) and includes rules on the admission of securities dealers as Exchange participants, the organisation of trading, clearing and settlement of trades on the Exchange, and monitoring and enforcement of the Trading Rules as well as the sanctions the Exchange may impose on participants and traders.


The Directives detail and underpin the Trading Rules of the Swiss Stock Exchange. Our Directives contain provisions on the Admission of Participants (including traders, reporting agents and market makers), Technical Connectivity for participants and Application Services Providers (ASPs), Trading, Market Control, Alternative Trading (specifically for the on-exchange trading services SwissAtMid and Swiss EBBO), Market Information and Sponsored Access.


The Guidelines encompass the Trading Parameters that set out the implementing ordinances for all markets and trading segments of the Swiss Stock Exchange, as well as the List of Charges under the Listing Rules, the List of Charges under the Reporting Rules and the List of Charges under the Trading Rules, which includes the various Liquidity Provider Schemes (LPS).
