Sygnum Integrates Sui, Expands Institutional SUI Access

Sygnum Bank has embraced Sui on its platform and is first Swiss bank to implement it in its platform under its FINMA license. As a staff of over 250 people in Switzerland, Singapore, Hong Kong and the UAE, Sygnum became a unicorn in early 2025 and currently oversees more than 4 billion value of customer funds.

Tech-edge at Sui

Sui promises to scale to 120,000 transactions per second and being low-latency and fast finality, a quality attracting institutional and developer interest. It can host AI-compatible smart contracts and decentralized applications, and it has more than 1.5 million daily active users and currently over 100 dApps. The total value locked of Sui has rampaged to more than $2 billion.

Market and Treasury movements

Mill City Ventures III has purchased close to half of a billion dollars face of SUI in an important institutional development that sent a strong treasury signal for Sygnum as well. By August 2, 2025, SUI stood in 14 th place on CoinMarketCap with a market capitalization of 13.8 billion. It may also require the disclosure of new rules as a result of such large positions of the treasury.

Yield, Liquidity and DeFi-TradFi Bridge

The new SUI staking service might attract returns between six and twelve percent, which falls above most of the conventional bank fees. Lombard loan, which are likely to be introduced in conjunction with staking, will introduce the possibility of unlocking liquidity without the net sale of assets with LTV conservative ratios of between 50% and 70%. This has seen the Sui Foundation appoint Sygnum as its banking partner, which would facilitate a closer link between traditional finance and the crypto industry. All these characteristics may be attractive to pension funds, institutional and family offices wishing to access token investments within a regulated environment.

Regulatory and Security concerns

Sygnum operates under the supervision of FINMA, but that does not mean that it has to negotiate cross-border regulatory territories, such as EU MiCA and even U.S. oversight, which may help to shape the plausibility of its SUI propositions. Smart contract risks will be an important assessment that will require security audits, and network outages and software weak points are operational concerns. Clear insurance and academic validation such as IEEE-reviewed studies will be necessary to institute trust at the institutional level.

Threats and Market Downturns

Volatility in SUI is an exposing factor in the market, especially when we take into account the aspect of collateralized loans, any immediate price decrease would initiate a liquidation. The focused ownership, like Mill City, can magnify a fluctuation of prices and in addition, a speculative inflow is possible after institutional declarations. Sygnum you also expects to add SUI staking and Lombard loans, where the clients will be able to lend their holdings as collaterals and at the same time remain exposed on the market. Margin call risk is likely to be reduced by strict LTV levels that banks are obligated to protect, but product economics can be changed in the short-term by regulatory shift.
