State Street Investment Management’s latest digital asset initiative is less about crypto speculation and more about something traditionally far less glamorous: cash management.
The asset manager, which oversees more than $5 trillion globally, has partnered with Galaxy Digital to launch the State Street Galaxy Onchain Liquidity Sweep Fund (SWEEP), a tokenized private liquidity fund designed to allow institutional investors to move stablecoins into yield-bearing assets on blockchain infrastructure around the clock.
The launch reflects a broader shift taking place across global finance as large asset managers increasingly experiment with tokenized versions of traditional money-market and Treasury-style products. Rather than targeting retail crypto traders, the focus is increasingly institutional: creating blockchain-based infrastructure for settlement, liquidity management, and collateral movement.
SWEEP launches initially on the Solana blockchain, with Ethereum and Stellar integrations planned later. The structure allows qualified investors to subscribe and redeem using stablecoins, including PayPal USD (PYUSD), while Galaxy provides the tokenization infrastructure and Anchorage acts as digital custodian.
The relevance of the announcement extends beyond the product itself. In traditional markets, institutional cash management is constrained by banking hours, settlement windows, and operational frictions. Tokenized liquidity funds aim to reduce those constraints by enabling 24/7 movement of cash-like assets across blockchain networks.
“State Street has played a leading role in market innovation for decades, from servicing mutual funds to launching ETFs, and we’re proud to continue that role as digital assets reshape market infrastructure,” said Yie-Hsin Hung, president and chief executive officer of State Street Investment Management. “This fund allows us to bring the TradFi landscape on-chain in a resilient way, guided by our long-standing focus on innovation, risk management,t and client outcomes.”
“For years we've argued that traditional finance and crypto would converge on the same rails,” said Mike Novogratz, founder and CEO of Galaxy. “We believe SWEEP is what that looks like in practice, with a fund managed by an experienced cash manager being available for investors on-chain, on infrastructure Galaxy built for institutions.”
SWEEP further expands and strengthens State Street Investment Management’s partnership with Galaxy. In September 2024, State Street Investment Management launched three actively managed ETFs sub-advised by Galaxy, focused on digital assets and disruptive technologies.
- HECO: An actively managed ETF combining blockchain-related companies and cryptocurrencies while using options strategies to help manage downside risk.
- DECO: An active digital asset ecosystem ETF investing in blockchain companies and cryptocurrencies, driving broader adoption of blockchain technology.
- TEKX: An active technology ETF focused on companies powering disruptive themes including artificial intelligence, blockchain, and digital infrastructure.
Tokenized Liquid Products Competition
The product also arrives as competition intensifies in tokenized Treasury and liquidity products. BlackRock’s BUIDL fund and FranklinTempleton’s on-chain money-market initiatives have already demonstrated growing institutional appetite for blockchain-based cash management structures.
Still, the sector remains controversial. Critics argue that tokenized finance often repackages conventional money-market products using blockchain rails without fundamentally changing underlying risks. Stablecoins themselves continue to face regulatory scrutiny around reserve transparency, liquidity stress, and operational resilience during market dislocations. Academic research and prior market events have highlighted the vulnerability of stablecoin ecosystems during periods of sharp deleveraging and liquidity stress.
For now, however, the direction of travel across large institutions appears increasingly clear. What began as cautious experimentation with crypto custody and Bitcoin ETFs is gradually evolving into broader attempts to rebuild parts of traditional financial infrastructure on blockchain networks.
State Street’s move suggests that tokenization is becoming less about speculative assets and increasingly about modernizing how institutional capital moves, settles, and earns yield.
