Switzerland's payment infrastructure is unique in Europe. As a non-EU, non-EEA country, Switzerland does not participate in SEPA for domestic payments. Instead, it operates its own clearing and settlement network built around the Swiss Interbank Clearing (SIC) system, operated by SIX Group under the oversight of the Swiss National Bank (SNB).
In August 2024, Switzerland launched SIC Instant Payments (SIC IP), bringing real-time payments to the Swiss franc for the first time. This guide explains how both systems work and what payment professionals need to know.
SIC - Swiss Interbank Clearing
What It Is
SIC is Switzerland's central payment system for CHF-denominated interbank transactions. It is a real-time gross settlement (RTGS) system that settles in central bank money held at the SNB. Every CHF payment between Swiss banks ultimately settles through SIC.
Who Operates It
SIX Group operates SIC on behalf of the SNB. SIX is also the operator of the Swiss stock exchange (SIX Swiss Exchange) and Switzerland's financial market infrastructure. The SNB provides the central bank accounts in which settlement occurs and maintains oversight of the system.
How It Works
Settlement: Gross settlement in real-time. Each payment is settled individually and irrevocably in central bank money. Participants: Over 300 financial institutions, including all major Swiss banks, cantonal banks, and foreign banks with Swiss operations. Volumes: SIC processes approximately 800,000 transactions per business day, settling over CHF 200 billion daily. Operating hours: Business days, approximately 17 hours per day (23:00 to 16:15 CET the following day). Messaging: ISO 20022 native. Switzerland was an early adopter of ISO 20022 for domestic payments, completing migration in 2018 - years ahead of SWIFT's CBPR+ timeline.
What Settles Through SIC
SIC handles the full range of CHF payment types: High-value interbank transfers: Large-value payments between financial institutions Retail payment clearing: Batch-processed retail payments (credit transfers, direct debits) clear through SIC Securities settlement: Cash leg of securities transactions on SIX Swiss Exchange Postal payments: PostFinance (Switzerland's postal bank) settles through SIC
Key Difference from European Systems
Unlike EU countries that use T2/TARGET for high-value RTGS and SEPA for retail clearing, Switzerland consolidates both functions in SIC. High-value and retail payments settle through the same infrastructure in central bank money. This simplifies the Swiss payment landscape but means Switzerland operates outside the SEPA network.
SIC IP - Instant Payments
The Launch
On 20 August 2024, SIX and the SNB launched SIC Instant Payments (SIC IP) - Switzerland's first real-time retail payment system. The launch followed the deployment of the SIC5 platform in November 2023, which provided the technical foundation for instant payments.
How It Works
Speed: Payments settle in under 10 seconds, 24/7/365 including weekends and public holidays. Settlement: Each instant payment settles individually in central bank money at the SNB. This is gross settlement - no netting, no deferred settlement, no credit risk. Currency: CHF only. Maximum amount: CHF 500,000 per transaction initially, with plans to increase. Messaging: ISO 20022 (pain.001 / pacs.008 message types). Irrevocability: Instant payments are final and cannot be reversed by the sender once confirmed.
Bank Rollout Timeline
Switzerland has adopted a phased mandatory rollout:
Phase 1 (August 2024): All banks that processed more than 500,000 incoming customer payments in SIC during 2020 were required to receive instant payments. This covered approximately 63 banks representing over 95% of Swiss retail payment volumes.
Phase 2 (by end of 2026): All remaining SIC participants active in retail payments - approximately 180 additional financial institutions - must be capable of receiving instant payments. This will achieve full market coverage.
Sending capability: Banks can choose when to offer instant payment initiation to their customers. The mandate covers receiving only - ensuring that any instant payment sent will be accepted by the receiving bank.
What Practitioners Should Know
-
Settlement in central bank money: Unlike some European instant payment systems that use commercial bank money or pre-funded positions, SIC IP settles in SNB reserves. This eliminates counterparty risk entirely.
-
No SEPA Instant interoperability: SIC IP is a domestic CHF system. Swiss instant payments do not interoperate with SEPA Instant Credit Transfer (SCT Inst) or TIPS. A payment from a Swiss bank to a German bank cannot travel via SIC IP - it requires correspondent banking or SWIFT.
-
TWINT integration: TWINT, Switzerland's leading mobile payment platform (5M+ active users), is expected to leverage SIC IP for settlement. This would move TWINT from batch settlement to real-time, improving the user experience for P2P and merchant payments.
-
Corporate adoption: The CHF 500,000 transaction limit makes SIC IP relevant for corporate treasury, not just retail P2P. Swiss corporates can use instant payments for supplier payments, urgent treasury transfers, and cash management.
Switzerland's Position in European Payments
Switzerland occupies a unique position. It participates in European financial markets through bilateral agreements but operates independently in payments:
SEPA: Swiss banks can participate in SEPA as third-country participants, but domestic CHF payments do not use SEPA rails. ISO 20022: Switzerland was a pioneer, completing domestic migration in 2018. This gave Swiss banks a head start on the messaging standard that SWIFT and EU systems are still rolling out. Cross-border: CHF cross-border payments use SWIFT or correspondent banking. CLS settles CHF FX transactions alongside other major currencies. Crypto and DLT: SIX operates SDX (SIX Digital Exchange), a regulated platform for tokenised securities. The SNB has participated in Project Helvetia, exploring wholesale CBDC settlement using DLT.

| Settlement | Central bank money (SNB) | Central bank money (ECB via TIPS) or commercial bank (RT1) |
| Operating hours | SIC: business days; SIC IP: 24/7 | TIPS: 24/7; RT1: 24/7 |
| ISO 20022 | Native since 2018 | Mandatory from 2023 (CBPR+) |
| Tx limit | CHF 500,000 (SIC IP) | EUR 100,000 (SCT Inst, increasing to EUR 999,999.99) |
| Cross-border | Domestic only | Pan-European (36 countries) |
| Operator | SIX Group | EBA Clearing (RT1) / Eurosystem (TIPS) |
Key Takeaway
Switzerland's payment infrastructure is well-engineered and increasingly modern. The SIC5/SIC IP launch places Switzerland alongside the EU in offering central-bank-money instant payments. The main limitation is insularity - SIC IP is CHF-only with no current path to SEPA interoperability. For multinational operations with Swiss exposure, this means maintaining separate payment connectivity for CHF alongside EUR SEPA rails.
