SIX, a Swiss exchange and financial market infrastructure provider, has received approval from the Swiss Financial Market Supervisory Authority (FINMA) to offer crypto asset custody services. According to ChainCatcher, SIX plans to integrate its previously independent digital central securities depository into its core subsidiary, SIX SIS AG, thereby unifying traditional securities and digital asset infrastructure. This integration allows financial institutions to manage stocks, bonds, and crypto assets under a single regulated framework, enhancing operational efficiency and legal certainty while reducing the complexity of switching between multiple systems. SIX aims to create a unified gateway connecting traditional finance with the digital economy, supporting integrated post-trade services across asset classes. Market observers believe this development signifies the maturation of regulated digital asset infrastructure and could accelerate institutional adoption of cryptocurrencies.
