SIX Group Services AG, headquartered in Zurich, builds and operates the financial market infrastructure that underpins Swiss and international capital markets. It runs SIX Swiss Exchange, part of Europe's third-largest stock exchange group, and provides the full post-trade stack - clearing, settlement, custody, and collateral management - that securities markets rely on daily. Its Financial Information division supplies market data, indices, and analytics to financial institutions worldwide.
Beyond capital markets, SIX maintains Switzerland's payment infrastructure: interbank clearing, card processing, and cashless payment solutions that support daily commerce for banks, merchants, and financial service providers. The company's operational footprint spans Switzerland and Spain, with clients and counterparties across Europe and globally.
SIX operates across four broad domains:
- Exchange operations - equities and other securities trading via SIX Swiss Exchange
- Securities services - post-trade infrastructure including clearing, settlement, and custody
- Financial information - market data, indices, and analytics for global institutions
- Banking and payments services - interbank clearing, card processing, and cashless payment solutions
