The choice between tokenized treasuries vs yield stablecoins determines how a corporate treasurer captures onchain yield without sacrificing liquidity or audit clarity. Tokenized treasuries are blockchain-issued shares of a regulated money-market or short-duration government-bond fund. Yield stablecoins are dollar-denominated tokens that pass through an underlying yield strategy. BlackRock's BUIDL fund crossed $3.0B in supply as of 2026-06-05 per DeFiLlama, while Ethena's USDe reached $4.5B over the same window. Both instruments compete for the same corporate cash dollar, but they sit on different sides of the securities line and behave differently in stress.
​

This piece compares the two categories across yield mechanism, regulatory wrapper, redemption, counterparty exposure, tax treatment, and composability, then maps each to the corporate cash buyer most likely to use it.
​

Tokenized treasuries are onchain representations of shares in a money-market or short-duration Treasury fund, registered as securities and transfer-agented offchain. Yield stablecoins are dollar-pegged tokens that distribute returns generated by an underlying strategy, ranging from T-bill collateral to delta-neutral basis trades, without necessarily being registered securities themselves.
​

The named instruments anchoring this comparison include BlackRock USD Institutional Digital Liquidity Fund (BUIDL), issued on Ethereum with Securitize serving as transfer agent, and Franklin Templeton's OnChain U.S. Government Money Fund (BENJI / FOBXX). Ondo Finance USDY wraps short-term Treasuries and bank deposits in a tokenized note for non-US holders. Superstate USTB targets qualified purchasers with a short-duration Treasury fund. Circle's USYC, acquired through Hashnote, sits between these worlds as a tokenized money-market product. On the stablecoin side, Ethena USDe generates yield by shorting perpetual futures against staked ETH collateral. Sky USDS (the Sky-branded stablecoin that DAI holders can optionally upgrade to 1:1) pays the Sky Savings Rate funded by a mix of T-bill RWAs and crypto-collateralized loans.
​

The structural distinction matters. BUIDL holders own beneficial interest in a fund. USDe holders own a token whose backing is a hedge book. The first is a regulated security under a 3(c)(7) wrapper. The second is a synthetic dollar with no SEC registration, distributed today only to permitted jurisdictions. See Securitize's BUIDL launch documentation for the legal structure.
​

Tokenized treasuries earn the risk-free rate by holding short-duration US government securities and repo, with yield distributed daily or accrued in NAV. Yield stablecoins earn through three different engines: T-bill backing passed through a token wrapper, delta-neutral basis trades funded by perpetual futures funding rates, or a savings rate sourced from a mix of RWA and onchain collateral.
​

Inside a tokenized treasury, the fund owns Treasury bills, agency paper, and overnight repo. BUIDL's portfolio is custodied with BNY Mellon, and Securitize acts as transfer agent maintaining the share register onchain. Yield posts daily as new tokens minted directly to the holder's wallet. Redemption converts tokens back to USD via a permissioned mint and burn at NAV, settling T+0 or T+1 depending on the issuer.
​

Ethena's USDe takes a different route. Collateral, primarily staked ETH, is deposited with off-exchange settlement custodians, then a matching short position on perpetual futures hedges price exposure. The combined book is delta-neutral, and the yield comes from staking rewards plus the funding rate paid by perpetual longs. Ethena publishes its methodology and reserve composition at ethena.fi. Funding can turn negative, which is the structural risk discussed below.
​

Sky's USDS pays the Sky Savings Rate to holders who deposit USDS for sUSDS. The rate is set by Sky governance and funded by a portfolio that includes tokenized T-bills, crypto-collateralized loans, and direct deposits with money-market funds. See the framework at sky.money. Rehypothecation rules differ across all three: a tokenized treasury fund does not rehypothecate holder assets, a delta-neutral stablecoin actively uses collateral as margin, and a savings stablecoin lends collateral into the broader Sky vault system.
​

The two categories diverge on six dimensions that matter to a treasurer: where the yield comes from, what regulatory wrapper holds the asset, how fast you can exit, who you are exposed to if something breaks, how the IRS treats the return, and whether the token plugs into DeFi collateral markets.

The wrapper choice cascades into every other column. A registered fund inherits the disclosure and custody regime of US securities law, which produces clean tax treatment and a known counterparty stack but also restricts who can hold the token and which protocols can accept it as collateral. A token without securities registration is composable everywhere but inherits issuer and exchange risk and an unsettled tax posture. The SEC's framing of these distinctions appears in its 2023 release on private fund advisers.
​

Buyer fit follows the regulatory wrapper and operational profile. Public-company treasurers gravitate to registered funds with familiar audit trails. Crypto-native startups can hold either but value composability. DAO treasuries weigh governance and onchain transparency. Fintech float operators care most about T+0 settlement and the ability to plug yield into customer-facing products.
​

A public-company treasurer at a Russell 3000 issuer faces an audit committee that wants 1940 Act protection, named custodians, and 1099 reporting. BUIDL or BENJI fit cleanly. The treasurer can subscribe through Securitize or Franklin's portal, hold tokens in a Fireblocks or Anchorage vault, and reconcile against a familiar NAV strike. Holding USDe or USDY in this context creates classification debates the CFO does not want to litigate quarter after quarter.
​

A crypto-native startup with a Cayman parent and an operating sub can hold yield stablecoins more comfortably. Ondo USDY is structured for non-US institutional holders and pays a daily yield accrual. USDe gives composability into Pendle and Morpho markets where a startup might already be earning fees. The audit posture is different because the auditor evaluates token positions at market, not at fund NAV.
​

DAO treasuries optimize for transparency and onchain enforcement. Many large DAOs hold a blend: tokenized treasuries for the conservative core, sUSDS or USDe for the yield-seeking tranche. The governance question is whether the treasury vote can approve a token that has issuer redemption gates. A DAO that cannot tolerate a 24-hour redemption queue should size yield stablecoins accordingly.
​

Fintech float operators, including payment companies that hold customer balances, want a token that settles instantly, distributes yield they can pass through, and is acceptable to their bank partners. BUIDL distributions hit the wallet daily, which simplifies pass-through accounting, but transfer restrictions complicate any customer-facing redemption. Circle's USYC, repositioned after the Hashnote acquisition at circle.com/en/usyc, targets this segment explicitly.
​

Tokenized treasuries inherit the operational risks of money-market funds plus smart-contract and transfer-agent failure modes. Yield stablecoins introduce funding-rate inversion, basis-trade unwind risk, and the depeg dynamics seen in stablecoin selloffs. The March 2023 USDC depeg around the SVB receivership is the standing case study for stablecoin reserve concentration.
​

In a money-market fund stress event, the typical break is a gate. The fund manager invokes a liquidity fee or temporary suspension of redemptions to protect remaining holders from a run. A tokenized treasury inherits that same mechanism, layered with the question of whether the onchain mint and burn function can be paused independently of the offchain redemption queue. Treasurers should read the fund prospectus to understand whether a gate stops only USD redemptions or also halts onchain transfers.
​

Delta-neutral stablecoins face a different failure mode. When perpetual funding turns persistently negative, the hedge book bleeds. Ethena addresses this with a reserve fund disclosed on its dashboard. A treasurer sizing USDe should map a multi-week negative funding scenario against reserve coverage. The March 2023 USDC episode, when USDC traded as low as $0.87 due to Silicon Valley Bank deposit exposure, shows how fast a stablecoin can move when its reserve composition surprises the market.
​

Tokenized treasury redemption gates are the third stress vector. BUIDL and BENJI both reserve the right to settle redemptions on a delayed basis under unusual market conditions. A treasurer who needs T+0 access during a stress event may find the redemption window stretched to T+2 or longer, which is exactly when a corporate buyer most wants liquidity. The secondary AMM market for these tokens is thin compared to the primary issuance, so exit through a DEX is not a reliable backstop.
​

Choosing between the categories reduces to five questions about the holder, the audit posture, the redemption clock, the composability need, and the tolerance for novel risk. The answers point to a registered fund, a yield stablecoin, or a blended allocation across both.

Pick a tokenized treasury if the holder values regulatory clarity, audit familiarity, and a known custody stack, and can accept permissioned transfer and lower composability. Pick a yield stablecoin if the holder values 24/7 secondary liquidity, DeFi composability, and broader jurisdictional access, and can underwrite issuer-specific reserve and funding risk. Many corporate treasuries hold a blend, sizing each by the question above.

Eco is a neutral aggregator and orchestration platform that helps institutional holders move stablecoins and tokenized assets across chains for working-capital deployment. Eco does not issue, custody, or trade these instruments. It connects to issuer mint endpoints, partner rails, and onchain liquidity so a treasurer can route the same dollar between markets without managing twelve separate integrations.
​

For tokenized treasuries, the transfer surface is constrained by the permissioned transfer list maintained by the issuer's transfer agent. Eco's role is to coordinate onchain settlement once a holder is on the approved list, and to surface best-execution data on the corresponding stablecoin leg when a treasurer converts a redemption into operating cash. For yield stablecoins, which trade freely on AMMs and through OTC desks, Eco aggregates primary mint access, secondary onchain liquidity, and offchain RFQ inventory into a single integration point. The live partner rail is Hyperlane, with CCTP used as internal transport inside Eco Routes for USDC legs.
​

The institutional value proposition is one integration across markets. A treasury team that already has KYB cleared with Eco can access mint, redeem, and route flows for multiple issuers without onboarding to each separately. That neutrality is the design choice. Eco is not the fastest path for a single venue, but it is the path that does not need to be re-architected when the corporate cash strategy rotates between BUIDL, USYC, USDe, and USDY.
​

The securities question is unsettled. Tokenized treasuries are explicitly registered securities. Yield stablecoins occupy a gray zone that depends on the issuance structure, the yield source, and the holder jurisdiction. US corporations can hold BUIDL subject to qualification thresholds and the issuer's onboarding process via Securitize.
​

The pending US stablecoin legislation, the Guiding and Establishing National Innovation for US Stablecoins Act (GENIUS Act, S.1582), draws a line around payment stablecoins that pay no interest to holders. A token that pays yield falls outside the payment stablecoin definition and is more likely to be analyzed under existing securities frameworks. Until the bill text is enacted, yield stablecoin issuers rely on jurisdictional carve-outs and Regulation S offerings to manage US holder exposure.
​

For BUIDL specifically, the fund is offered under Rule 3(c)(7) of the Investment Company Act and requires qualified purchaser status, generally meaning $25M in investments for an entity. A US corporation that clears that threshold can subscribe through Securitize and hold the token in any compatible custodian. Daily yield distributes as additional BUIDL tokens. Redemption converts BUIDL back to USD at NAV through the same portal.
​

The total stablecoin market reached $315.3B as of 2026-06-05 per DeFiLlama, with yield-bearing tokens still a minority of supply. Tokenized treasury supply, while smaller in aggregate, is growing faster on a percentage basis as new issuers come to market. The two categories are converging in audience, diverging in structure, and the choice for any specific corporate cash mandate sits on the five questions above.
