Tokenized Treasuries and On-Chain Cash Management: A New Tool for Digital Asset Funds

Tokenized US Treasuries have moved from concept to institutional infrastructure. The market has crossed $15 billion in 2026, with leading products from BlackRock, Circle, Franklin Templeton, Ondo Finance, Centrifuge and WisdomTree producing daily yield accruals against short-dated US government instruments held in regulated SPV structures. For digital asset funds, the implications go beyond a new yield instrument. Tokenized Treasuries reshape cash management, intra-day collateral mechanics, settlement infrastructure and the way institutional fund treasuries earn yield on idle balances. The strategic question for managers is no longer whether to engage with tokenized Treasuries. It is how to integrate them into the fund's treasury and collateral architecture.

"Tokenized Treasuries are not a crypto product. They are a US Treasury product with a blockchain settlement layer. The institutional value proposition is the combination of regulated yield with the operational efficiency of on-chain settlement. For digital asset funds, this is the first instrument that gives the treasury function genuine yield without exiting the operational rails the fund already uses." David Lloyd, Chief Executive Officer of CV5 Capital

The Market Has Crossed Institutional Scale

The tokenized Treasury market has matured rapidly. Total tokenized Treasuries grew from approximately $5 billion at the start of 2025 to approximately $15.07 billion by late April 2026, with consistent month-over-month inflows reflecting structural demand rather than isolated launches. The top five products together account for roughly 68 percent of the entire sector. The top 20 issuers collectively manage approximately $13.5 billion, indicating that while competition is intensifying, the market remains concentrated among regulated, institutional-grade issuers.

The Three Strategic Use Cases for Digital Asset Funds

Use Case One: On-Chain Cash Management

The simplest and most immediate use case is treasury yield on idle stablecoin balances. A digital asset fund typically maintains material stablecoin balances for operational reasons: pending subscription proceeds awaiting deployment, redemption reserves, intra-month rebalancing buffers and exchange collateral above margin requirements. Historically, these balances earned nothing. With tokenized Treasuries, the fund's treasury policy can specify the systematic conversion of idle stablecoin balances into a tokenized Treasury position, capturing approximately 4 to 5 percent yield while preserving the option of converting back to stablecoin within the same blockchain settlement window.

The economics are material. A digital asset fund holding 10 percent of $100 million NAV in working stablecoin balances generates approximately $400,000 to $500,000 of additional annual yield by deploying those balances into tokenized Treasuries. For larger funds, the figure scales linearly. The yield is generated within the regulated SPV that backs the tokenized product, not from an on-chain protocol, and is therefore qualitatively different from the yield available in DeFi protocols.

Use Case Two: Collateral in Derivatives Markets

The use case that has driven Circle USYC's overtaking of BUIDL is the deployment of tokenized Treasuries as productive collateral in derivatives markets. USYC's rise has been driven by integration on BNB Chain, where $1.84 billion of USYC supply has been pledged into trading collateral. The institutional implication is that a fund running a derivatives strategy can post tokenized Treasury collateral that simultaneously earns yield and supports the trading position, capturing the spread between collateral yield and financing costs in a way that traditional cash collateral cannot.

Circle CEO Jeremy Allaire has described tokenized Treasuries as collateral as a major emerging use case. The structural implication for digital asset funds running basis, options or perpetuals strategies is that the carry on collateral can become a meaningful component of total return, materially improving the strategy's risk-adjusted profile.

Use Case Three: Settlement Bridge for Subscriptions and Redemptions

The third use case is operational rather than economic. Tokenized Treasuries provide a settlement bridge between fiat-funded subscriptions and on-chain deployment. Rather than holding subscription proceeds in non-yielding bank deposits during onboarding and AML processing, the fund can deploy proceeds into tokenized Treasuries and capture yield through the onboarding window. The same logic applies to redemption reserves, which can be held in tokenized form rather than non-yielding stablecoins, with conversion to stablecoin at the redemption date.

The Six Operational Considerations

1. Legal Structure and SPV Design

Tokenized Treasuries are not direct holdings of US Treasury bills. The token represents an interest in a regulated SPV that holds the underlying instruments. The strength of a token holder's claim depends on the legal structure of the SPV, specifically whether it provides bankruptcy remoteness and how the holder's claim is documented. Institutional integration requires the legal review of the SPV structure to be completed before the fund's valuation policy includes the instrument.

2. Yield Distribution Mechanism

Tokenized Treasuries distribute yield through one of three mechanisms: accruing tokens (price increases as yield accumulates, balance constant), rebasing tokens (price stable near $1, balance increases) or separate stablecoin distributions. Each mechanism has different implications for accounting, NAV calculation, tax treatment and DeFi compatibility. The fund's valuation policy must specify the treatment for each token held.

3. Custody and Multi-Chain Support

The largest products are now live across multiple blockchain networks. BUIDL operates on nine networks; USYC has a strong presence on BNB Chain; products span Ethereum, Solana, Stellar, Avalanche, Polygon and Arbitrum. The fund's custody infrastructure must support each chain on which the fund holds positions, with reconciliation procedures that aggregate balances across chains.

4. AML and Eligible Investor Frameworks

Most tokenized Treasury products are restricted to qualified or accredited investors. The fund's onboarding records must include the relevant qualification documentation, and the fund's holdings of restricted tokens must be reported in compliance with the issuer's transfer restrictions.

5. Smart Contract and Counterparty Risk

The underlying US Treasuries carry minimal credit risk. The tokenized layer introduces additional risk surfaces: smart contract risk, redemption-delay risk, oracle risk where applicable, and counterparty risk to the issuer's transfer agent. Documented risk treatment, including issuer concentration limits and contingency procedures, is part of institutional integration.

6. Independent Valuation and Reporting

The administrator must be capable of valuing tokenized Treasury positions on each NAV date, reconciling the on-chain balance to the issuer's reported NAV, and reflecting the position in the fund's financial statements with appropriate disclosure. The administrator's specific capability for tokenized assets is a meaningful institutional differentiator.

Integration into the Fund's Treasury Policy

Institutional integration of tokenized Treasuries requires updates to several governance documents:

• The treasury policy specifies which tokenized Treasury products are approved, the maximum percentage of fund NAV that may be deployed at any time, and the sweep cadence converting idle stablecoin to tokenized Treasury and back.
• The valuation policy specifies the pricing source for each token, the treatment of accruing versus rebasing structures, and the procedure for handling issuer-reported NAV deviations from the price observed on-chain.
• The AML policy addresses the eligible investor declarations required to hold restricted products, and the procedure for handling token transfers within the fund's treasury wallets.
• The offering memorandum disclosure addresses the use of tokenized Treasury products as both an investment exposure and a treasury management tool, with the specific risks identified.
• The board record evidences review and approval of each new tokenized Treasury product before its inclusion in the treasury programme.
