Swiss Bank Sygnum Launches Institutional $SUI Custody and Trading Services

Swiss digital asset bank Sygnum has expanded its institutional-grade services to include support for the $SUI token, native to the Sui blockchain. Effective as of August 8, 2025, the integration provides custody, trading, staking, and collateralized lending capabilities for $SUI, offering professional investors a secure and compliant way to engage with the asset [1]. This development marks a significant milestone in Sygnum’s ongoing efforts to enhance its digital asset platform and meet growing institutional demand for regulated crypto services [2].

The custody service for $SUI is structured under Swiss banking regulations, addressing concerns over on-chain risk and offering a secure alternative to on-exchange holdings [1]. This is particularly relevant for asset managers and institutional clients seeking to diversify their portfolios while maintaining regulatory compliance. Through Sygnum’s trading desk, institutional clients can now directly buy and sell $SUI, with settlement options including both on-chain and fiat, broadening the availability of layer-1 assets within the bank’s global portfolio [1].

Looking forward, Sygnum plans to introduce staking services for $SUI, allowing clients to earn rewards on their holdings with full operational transparency and regulatory oversight. The bank also announced its intention to offer collateralized lending, enabling institutions to generate liquidity from $SUI holdings without the need for forced sales [1]. These features align with Sygnum’s broader strategy to provide comprehensive, secure, and compliant digital asset services for institutional clients [2].

The move is supported by a $450 million commitment from Mill City Ventures, a fund managed by Galaxy Digital, to invest in $SUI assets [1]. This substantial backing signals strong institutional confidence in the token and is expected to drive increased liquidity and trading volumes for $SUI, positioning it alongside other major digital assets like ETH and BTC [1].

Sygnum’s collaboration with the Sui Foundation has played a crucial role in this expansion, enhancing access to the Sui blockchain and reinforcing Switzerland’s reputation as a leading hub for digital asset banking [1]. The integration also reflects a broader trend in the financial industry, with more banks offering institutional-grade crypto services in response to tightening regulations and security concerns following major exchange incidents [1]. This follows similar moves by BBVA and BNY Mellon, which have also launched fiat-plus-crypto custody services [1].

For institutional investors, the integration of $SUI into Sygnum’s platform offers scalable exposure to Sui and a full suite of financial activities, all conducted under a regulated framework. For the Sui Foundation, the move represents a key step toward institutional adoption and sets a new benchmark for digital asset management [1]. Sygnum, now among the first Swiss banks to offer a comprehensive $SUI service, continues to strengthen its position as a leading player in the evolving digital asset landscape [2].
