Swiss franc stablecoin sandbox launches through 2026 as banks test regulated payments

Major banks and crypto firms in Switzerland are collaborating on a new swiss franc stablecoin initiative to test digital money infrastructure at scale.

Swiss financial institutions launch CHF stablecoin sandbox

A consortium of Switzerland’s leading financial institutions has started a live trial for a regulated Swiss franc stablecoin, seeking to build a digital settlement layer for the national economy. The initiative includes UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, BCV and Swiss Stablecoin AG, according to a statement from Sygnum.

The sandbox environment will run through 2026 and stays open to additional banks, companies and institutions that want to contribute to CHF stablecoin development. Moreover, the group is positioning the project as a neutral platform for the broader Swiss financial ecosystem, not a closed club for incumbents.

According to Sygnum, the setup is a controlled live environment that allows participating institutions to test digital financial products under realistic conditions. However, the sandbox operates with defined safeguards, including transaction limits and a restricted pool of participants, to manage operational and regulatory risk.

Objectives of the Swiss stablecoin sandbox

The participating firms said the initiative aims to support the emergence of a Swiss digital money ecosystem based on blockchain infrastructure. Moreover, they want to build concrete operational expertise in blockchain-based payments and settlements, moving beyond small-scale experiments toward live transaction flows.

In addition, the sandbox is intended to generate practical insights into new digital payment methods that could complement existing systems. That said, work on a regulated swiss franc stablecoin remains exploratory, with the long-term model still subject to regulatory, technical and market feedback from the trial.

Global context: accelerating stablecoin usage

The Swiss project comes as stablecoin adoption accelerates worldwide and market structure evolves. On March 31, analysts at Standard Chartered highlighted in a research note that global stablecoin velocity has roughly doubled over the past two years, a notable shift in transactional behavior.

They calculated that stablecoin tokens now turn over about six times per month on average. Geoffrey Kendrick, Standard Chartered’s global head of digital assets research, wrote that this increase in velocity contradicts the bank’s previous assumption that the metric would remain largely stable over time.

Despite the changing dynamics, Standard Chartered still expects overall stablecoin supply to expand significantly in the medium term. Moreover, the bank forecasts that total issuance could reach $2 trillion by 2028, underscoring how central tokenized money may become to cross-border and on-chain finance.

Market structure of leading USD stablecoins

While Swiss institutions test their own models, the current market remains dominated by USD-pegged tokens. According to The Block’s data dashboard, total supply for dollar-linked stablecoins stands at $298.5 billion, highlighting the scale of existing ecosystems that any new initiatives must interface with.

Tether’s USDT is the clear market leader, with a market capitalization of $184 billion, representing nearly 62% of total USD stablecoin supply. Furthermore, Circle’s USDC ranks second at approximately $78 billion, giving it a share of about 26% and reinforcing the concentration of liquidity in a few key issuers.

Implications for Switzerland’s digital money strategy

For Switzerland, the sandbox represents a bank-led approach to tokenized money that may sit alongside public sector initiatives. Moreover, integrating a Swiss franc-pegged token with existing banking infrastructure could help ensure compliance, risk controls and alignment with current financial regulation.

The multi-year horizon through 2026 gives UBS, PostFinance, Sygnum and their partners time to refine technology, governance and use cases before considering broader rollout. Ultimately, the results of this live trial will shape how Swiss institutions position themselves in an increasingly tokenized global financial system.

In summary, the collaborative sandbox offers Switzerland a structured way to test a regulated stablecoin tied to the franc, while gathering real-world data as global stablecoin markets continue to expand and evolve.
