A press release titled, "Stable Sea Expands WisdomTree Relationship With Two New Tokenized Funds for Business Cash" tells us, "Stable Sea ... announced it is expanding its strategic relationship with WisdomTree (WT) ... by adding two new tokenized funds to Stable Sea Terminal: the WisdomTree Short-Duration Income Digital Fund (WTSIX) and the WisdomTree Floating Rate Treasury Digital Fund (FLTTX). The newly added funds build upon current access to the WisdomTree Treasury Money Market Digital Fund (WTGXX) on Stable Sea Terminal that began in April 2026, giving finance teams a choice of tokenized, SEC-registered funds to manage operating cash directly inside their treasury workflow."
The release speculates, "US businesses collectively hold more than $5 trillion in cash and cash-equivalent accounts that generate minimal to no interest, even as the infrastructure to deploy that cash has matured significantly. Tokenized real-world assets (RWAs), led by U.S. Treasury and money market products, have grown from roughly $6 billion in early 2025 to more than $31 billion by mid-2026, according to industry tracker RWA.xyz, a more than fivefold increase in about 18 months. Tokenized Treasury and money market products alone now account for more than $15 billion of that total, as industry-leading asset managers, including WisdomTree, bring institutional-grade, SEC-registered products onchain."
It claims, "Despite that growth, most of the benefit has flowed to large institutions, crypto-native firms, and high-net-worth investors. Businesses that fall outside of these sectors -- those managing payroll, vendor payments, and working capital rather than a trading desk -- have largely been left out, limited not by demand but by high investment minimums, multiple account requirements, and manual back-office processes."
Tanner Taddeo, CEO and Co-Founder of Stable Sea comments, "US businesses collectively hold more than $5 trillion in cash and cash equivalent accounts that earn minimal to no interest, and most of them have no simple way to change that. `Adding WTSIX and FLTTX gives finance teams real choice -- not just a single yield-bearing option, but a ladder of tokenized funds they can match to the cash flow needs of their business. That's the same kind of cash segmentation large treasury desks have used for decades, now available to any operator inside one platform."
The release adds, "Stable Sea Terminal gives finance teams a single cash management platform where they can choose to put idle cash to work across various tokenized funds. With this expansion, eligible Terminal users may choose among three tokenized WisdomTree funds, each with different investment objectives and characteristics: WisdomTree Treasury Money Market Digital Fund (WTGXX) - An SEC-registered money market fund investing in short-term, U.S. Treasury securities, with daily dividend accrual, a 0.25% expense ratio, $1 minimum and SEC yield (7-day) of 3.46%. WisdomTree Floating Rate Treasury Digital Fund (FLTTX) - An SEC-registered fund that seeks to track an index, before expenses, of floating-rate US Treasury obligations, with a 0.05% expense ratio, $25 minimum, and SEC yield (30-day) of 3.75%. WisdomTree Short-Duration Income Digital Fund (WTSIX) - An actively managed fund seeking income consistent with preservation of capital, with a 0.40% expense ratio, $25 minimum, and SEC yield (30-day) of 4.41%."
WisdomTree's Will Peck adds, "Businesses of every size are looking for ways to put idle cash to work, and onchain yield-generation gives them access to financial products once reserved for institutional treasury desks. Bringing WTSIX and FLTTX to the Stable Sea Terminal extends that access to a new audience, in a format built for how finance teams already operate, rather than asking them to adapt to new infrastructure."
In other news, BNY recently published, "Collateral Management in an Always-on Market," which states, "Collateral management plays a foundational role in financial markets, driving core liquidity, funding, and risk management practices across the industry. In today's markets, the ability to identify, allocate, and move collateral efficiently has real financial consequences, directly influencing funding costs, balance sheet flexibility, liquidity, and an institution’s ability to act with confidence in changing market conditions."
They write, "Historically, many institutions approached collateral management through separate but connected functions: treasury managed funding strategy and liquidity needs; securities finance teams executed repo funding, managed lending activity, and sourced collateral market opportunities; operations teams managed margin, settlement, and day-to-day collateral movements; trading desks executed trading, hedging, and financing decisions; and investment teams managed portfolios within their own mandates. These groups collaborated where needed, but the operating model was generally built around distinct responsibilities, systems, and asset pools. That approach worked when markets moved more slowly and liquidity needs were more predictable. In today’s markets, where funding decisions, margin requirements, and settlement obligations can shift quickly across regions and products, and a change in one can affect the others, that approach has become more difficult to sustain."
BNY explains, "The direction of travel is clear: cash, collateral, and margin workflows are becoming faster, more global, and more interconnected. Settlement cycles are compressing, with the U.S. moving to T+1 for applicable securities transactions in 2024 and the UK and EU set to follow in 2027. As settlement windows shorten, collateral mobility will need to keep pace. Institutions will need to understand not only where assets can be financed in normal conditions, but how they can be pledged, transformed, or reallocated across private funding markets and public-sector liquidity facilities when conditions change. This interoperability can help preserve optionality, reduce trapped liquidity, and deploy collateral where it has the greatest funding value."
They comment, "Market innovation is also shifting liquidity management from an overnight orientation toward more precise intraday tools. BNY's intraday triparty repo capabilities, including its recent pilot of the first-ever GBP intraday triparty repo, demonstrate how market participants can source liquidity for specific periods, such as early morning funding needs, rather than relying on a full overnight funding window. This ability to access liquidity more precisely can help institutions manage funding costs, improve collateral efficiency, and better align available liquidity with actual obligations."
BNY's piece states, "Digital asset innovation is accelerating this shift. As adoption increases, tokenization could have a meaningful impact on collateral markets by enabling assets, cash, and eligibility rules to interact more efficiently. A practical building block in that evolution is the digitization of collateral schedules, which can help convert complex eligibility terms into more structured, usable data that supports optimization decisions. Over time, optimization may evolve toward programmable eligibility, tokenized ownership records, near-real-time settlement, automated substitutions, and more continuous liquidity management, helping connect collateral, cash, and settlement workflows across traditional and digital infrastructure. However, programmability alone is not optimization. Effective collateral management requires balancing liquidity, funding, eligibility, capital, and opportunity cost considerations across the enterprise. These continuous decisions must be connected across collateral, cash, funding, margin, and settlement workflows, spanning both traditional and digital rails."
Finally, they tell us, "Traditional custody, triparty, and collateral infrastructure will need to operate alongside digital cash, tokenized funds, and blockchain-based records as markets move closer to a 24/7 environment. In the near term, this will lead to a hybrid model which may add complexity as institutions manage collateral across both traditional and digital rails, connecting collateral, cash, and settlement activities across multiple infrastructures. Institutions that proactively evaluate their collateral frameworks, and invest in the operational, governance, and connectivity capabilities required, will be best positioned to navigate this transition."
