$1B Sygnum Bank Backs SUI Coin in $450M Treasury Partnership

Sygnum Bank, a $1 billion Swiss bank, has announced that it will provide SUI with a range of institutional-grade services. Galaxy Digital has partnered with Mill City Ventures to oversee its $450 million SUI treasury. These actions highlight Sui’s development as a blockchain ecosystem designed for widespread use.

Sygnum Bank Expands Institutional Access to SUI

Sygnum Bank has become the first Swiss bank to integrate SUI into its regulated banking platform fully.  In a new blog post, they officially announced the launch of custody and trading services for the token. Acting as the official banking partner to the Sui Foundation, Sygnum is expanding regulated access to Sui for professional and institutional investors worldwide.

The bank’s offerings include secure off-balance sheet SUI custody, spot, and derivatives trading. They also shared that staking and Lombard loans backed by SUI collateral would soon be launched. This approach ensures client assets remain bankruptcy-remote while benefiting from bank-grade infrastructure.

“Broadening institutional access to the Sui ecosystem further expands Sui’s reach to the global institutional investor community,” Christian Thompson, Managing Director of the Sui Foundation, said.

Sygnum’s Co-Founder and CEO, Mathias Imbach, highlighted that the bank’s position at the intersection of regulated finance and digital assets uniquely positions it to support the blockchain’s long-term growth. By pairing Swiss banking security with Wall Street-grade asset management, the altcoin could be a core asset in both private and public market investment strategies.

In response to the news, the SUI price rose by 2.7% to $3.81. The rally adds to a 9.5% gain over the past week and a 29.4% surge in the last month.

Mill City and Galaxy Digital Form $450M SUI Treasury Partnership

In a separate but equally significant move, Mill City Ventures announced a strategic partnership with Galaxy Digital to manage a $450 million SUI treasury strategy. This is the largest SUI treasury currently in public markets and the only one directly supported by a foundation.

Under the agreement, Galaxy Asset Management will act as asset manager, providing execution, liquidity solutions, and staking strategies to maximize the holdings over the long term. Galaxy Digital is also a major investor in Mill City, having participated in the $450 million private placement used to fund the treasury.

Stephen Mackintosh, Mill City’s CIO, described Sui as “the infrastructure layer for the next chapter of the internet.” He also emphasized the long-term nature of their holdings.

“Having the support of Galaxy as both asset manager and investor is a major unlock. Their institutional-quality infrastructure will allow us to actively manage our SUI treasury for both today and tomorrow. By working with Galaxy, we are getting closer to realizing the Web3 future that only Sui can make possible,” he noted.

Steve Kurz, Global Head of Asset Management at Galaxy Digital, said Mill City’s public-market structure creates “a new access point for investors to engage with transformative blockchain ecosystems.”  He framed the partnership as a step toward integrating digital assets into the heart of capital markets.
