The SIC system processes interbank payments in francs on behalf of and under the supervision of the Swiss National Bank. In association with SECB Swiss Euro Clearing Bank, SIX Interbank Clearing provides the processing of euro transactions through the euroSIC system on behalf of the Swiss financial center. Both interbank systems provide financial institutions within Switzerland and beyond its borders with efficient access to national and international payment traffic.

SIX Interbank Clearing contributes significantly to the attractiveness of the Swiss financial center, due in no small part to its low-cost payment traffic services which meet the most stringent of quality requirements in reliability, efficiency, and security.
