SIX

The main activity of SIX Group is the provision of innovative and secure financial infrastructures. The company offers services in the areas of the stock exchange, post-trade (clearing, settlement, custody), payments, financial information and data management. SIX Group primarily serves financial institutions, banks, asset managers, corporations and other players in the financial sector, in Switzerland and internationally.

SIX is a Swiss company that operates the infrastructure of the Swiss and Spanish financial centers, providing services in the areas of securities, financial information, and payments. Here are the major milestones in its history and development:

• Creation: SIX was formed from the merger of several Swiss financial infrastructures, bringing together the Swiss stock exchange, payment services, and financial information services to create an integrated and efficient platform for the financial sector.
• Product development: The company offers a wide range of services, including management of the Swiss stock exchange (SIX Swiss Exchange), interbank payment management, clearing and settlement services, securities custody, provision of financial data, as well as solutions for digital assets.
• Partnerships and acquisitions: SIX strengthened its international position by acquiring BME (Bolsas y Mercados Españoles), the operator of the Spanish stock markets, which allowed it to expand its activities in Europe. It also develops strategic partnerships, for example with banks for direct market access or with fintechs through its investment fund SIX FinTech Ventures.
• Strategic changes: The company has committed to the digitalization of financial services, innovation (notably in blockchain and digital assets), and sustainability, by developing ESG products and engaging in the transformation of the financial sector.
• Current position: Today, SIX is a key player in European financial infrastructure, recognized for the security, stability, and efficiency of its services, while pursuing a strategy of innovation and international expansion.

SIX Group does not have a single identified founder, as it is a company resulting from the merger of several Swiss financial infrastructures. It was created in 2008 by the merger of SWX Group, SIS Group, and Telekurs Group.
