Swiss Banks Launch CHF Stablecoin Sandbox

Swiss Banks Test BTC-Backed Stablecoins

UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, Banque Cantonale Vaudoise, and Swiss Stablecoin AG have launched a sandbox in Switzerland to test Swiss franc stablecoin usage scenarios. The initiative, announced on Wednesday, will enable participating banks to test selected stablecoin usage scenarios in a secure digital live environment. The project aims to gain experience in managing digital payment methods. The sandbox will be conducted in 2026, with Swiss Stablecoin AG providing the issuance infrastructure. Other banks, companies, and institutions can also join the project. These tests could increase stablecoin liquidity on BTC detailed analysis platforms.

CHF Stablecoin Sandbox and BTC Ecosystem Integration

This initiative is the latest step in Switzerland’s major banks’ efforts to integrate blockchain-based financial applications with the Swiss franc. Bitcoin Suisse AG had previously issued the Swiss franc-based XCHF stablecoin but announced on August 16, 2024, that it was suspending issuance and redemption operations. In September 2025, UBS, PostFinance, and Sygnum Bank completed a tokenized deposit POC under the Swiss Bankers Association, testing legally binding interbank payments on a public blockchain. Stablecoins can accelerate BTC adoption in Europe by balancing volatility in BTC futures transactions.

Bank Assets and Future Perspective

UBS Group is the largest with 1,7 trillion dollars in total assets, Raiffeisen Schweiz 353 billion dollars, Zürcher Kantonalbank 241 billion dollars, and PostFinance 121 billion dollars in assets (according to Advratings data). This sandbox is a critical step toward making Switzerland a crypto hub by integrating BTC trading with regulated stablecoins.
