Securities trading via SIX Swiss Exchange
SIX operates the Swiss Stock Exchange. The core functions of SIX Swiss Exchange are the admission of securities, the operation of the trading platform, the monitoring of trading and the distribution of market information. Shares, bonds, derivatives, investment funds and certificates, among others, are traded on the joint trading platform of the SIX Swiss Exchange and SIX Structured Products Exchange.As an independent unit within SIX, Exchange Regulation assumes all tasks within the framework of the self-regulation provided for by the Stock Exchange Act. The unit is separate from the operational business and issues rules for issuers and participants, monitors trading and enforces the rules.
Post-trade settlement and other securities services
Once an exchange trade has taken place, SIX takes over all subsequent processes. The SIX Securities Services division acts as a counterparty between trading parties throughout Europe. This service serves to reduce the risks of both buyers and sellers. Thereafter, SIX settles the transactions electronically. This includes real-time payments from one bank to another.SIX also operates systems that protect assets and documents from unauthorized access. The company acts as the central securities depository for Switzerland in this area. It holds in safe custody most of the financial instruments issued under Swiss law. SIX also offers its custody service for foreign securities.
The «Securities Services» division also includes platforms for direct debits and e-bills as well as the electronic information portal for land register data in Switzerland. It is called Terravis and enables mortgage, property and commercial register transactions.
SIX Interbank Clearing
SIX Interbank Clearing AG, based in Zürich, Switzerland, is a subsidiary of SIX Group. Since 1987 SIX Interbank Clearing has operated on behalf of the Swiss National Bank a payment platform for the processing of domestic and international payments in Swiss francs and, since the introduction of the euro, also of payments in euros. This platform - which includes the Swiss Interbank Clearing system for francs and Swiss Euro Clearing Bank for euros - connects virtually all Swiss financial institutions and a number of banks outside Switzerland. This makes it possible for financial institutions worldwide to handle electronic payments in euros and Swiss francs in Switzerland around the clock in real time.SIX Interbank Clearing also participates in various committees to standardize national and international payments and maintains the tables, history and ongoing discussion for ISO 4217, the ISO standard that defines international currency codes.
Swiss Euro Clearing Bank
The Swiss Euro Clearing Bank or SECB is a special-purpose bank based in Frankfurt, Germany, whose role is to facilitate transactions in euros by banks in Switzerland and Liechtenstein. It is the centerpiece of the euroSIC system, which is the euro counterpart to the Swiss Interbank Clearing system for transactions in Swiss francs.SECB was established in 1998 and started operations on, the same day as the euro was introduced as single currency of 11 member states of the EU. It settles transactions in euros that are processed on the SIC system, thanks to its access to the TARGET Services platform of the Eurosystem.
Use of SECB is not obligatory. In the mid-2000s, UBS preferred to process transactions in euro via its own direct access to the German real-time gross settlement system, which was subsequently replaced by TARGET2.
Originally owned by several Swiss financial sector participants, SECB has been a fully owned by SIX Group since 2018.
