SIX to Consolidate Digital and Traditional Assets Under Single CSD
SIX has secured approval from the Swiss Financial Market Supervisory Authority (FINMA) to merge its digital entity, SIX Digital Exchange (SDX) AG, into its central securities depository (CSD), SIX SIS AG. This consolidation will integrate digital asset capabilities into the core post-trade infrastructure. It will create a unified legal framework for traditional securities and digital assets. SIX is the Swiss financial infrastructure provider.
Expanding Institutional Crypto Custody
Beyond the merger, FINMA has authorized SIX to offer crypto custody services through its licensed CSD. This approval lets financial institutions utilize the same regulated, resilient infrastructure they currently employ for traditional securities to manage crypto assets. The organization aims to simplify the operational complexity of handling diverse asset classes under a single, scalable environment by bridging these two domains.

Vision for Pan-European Integration
The recent regulatory approvals are central to the group’s “one plug to two worlds” model. That facilitates seamless access to both digital and traditional financial markets. The objective is to leverage the high standards of established financial market infrastructure. It will support the innovation of digital assets, according to leadership at the firm. This transition aligns with the company’s broader roadmap to evolve into a leading pan-European provider of integrated, regulated digital post-trade solutions by 2030.
