Swiss Bank Sygnum Launches Regulated SUI Custody and Trading for Institutions

Sygnum, a Swiss digital asset bank, is expanding regulated institutional access to the Sui blockchain with new custody, trading and lending products for its professional clients.

The Zurich- and Singapore-headquartered firm announced Friday it will now offer institutional-grade custody, spot and derivatives trading for SUI, alongside upcoming staking and SUI collateral-backed Lombard loans. Staking is expected to launch in the coming weeks, with loans scheduled for the fourth quarter. All SUI holdings will be kept off the bank’s balance sheet and set up to be bankruptcy remote.

The move builds on Sygnum’s July 2025 integration of SUI into its platform, which it says made it the first Swiss bank to fully support the token. By working with the Sui Foundation, Sygnum aims to channel demand from banks, asset managers and high-net-worth individuals seeking secure, regulated exposure to blockchain ecosystems.

Christian Thompson, managing director at the Sui Foundation, said the partnership strengthens Sui’s connection to global institutional investors through a trusted, regulated gateway. Sygnum co-founder and CEO Mathias Imbach said the bank’s role is at the “intersection” of digital assets and traditional finance, helping clients access new opportunities within a regulated framework.

Sui, developed by former Meta engineers at Mysten Labs, uses parallel transaction processing to improve scalability, akin to cloud-based services. It supports decentralized finance, instant payments, real-world asset tokenization and gaming, and has positioned itself early in the BTCfi segment, which lets bitcoin holders participate in DeFi without compromising security.

Sygnum holds banking and digital asset licenses in Switzerland, Singapore, Abu Dhabi, Luxembourg and Liechtenstein, and offers services including regulated banking, asset management, tokenization and B2B solutions.

At press time, according to CoinDesk Data, SUI was trading at $3.84, up 4.5% in the past 24 hours.
