Real-Time, Risk-Free Liquidity Management

euroSIC offers online liquidity management and automatically checks whether a payment order is sufficiently coveredby funds. All participants maintain a settlement account that the euro payment system balances daily using a sight deposit account at the Swiss Euro Clearing Bank (SECB).

euroSIC only executes a transaction irrevocably and finally once this check has confirmed that the necessary funds are available. Otherwise, the transaction is routed to a wait file and kept pending until sufficient funds have become available through a liquidity supply. The payment beneficiary can then immediately access the credited amount without exposure to credit and liquidity risks.

Interfaces and Security

Banks connect to the SIC and euroSIC payment systems via Messaging Gateway, Swift or the web portal. SASS and Secure Swiss Finance Network (SSFN) ensure the highest possible level of security for both hardware and software.
