Tokenized treasuries explained: how T-bill tokens yield and who holds them

For years, the most common criticism of crypto finance was that its yields had no anchor: double-digit returns generated by leverage, token emissions and speculation, with nothing behind them but other participants’ willingness to pay. Tokenized treasuries are, in effect, the industry’s answer to that criticism. A tokenized treasury is a blockchain token whose value is backed by actual United States Treasury bills — short-term government debt — held somewhere, by someone, in someone’s legal name. The yield it pays is not manufactured by protocol design or paid by the next depositor; it is the interest rate the US government pays for borrowing money, passed through to the token holder after fees. This is why the category has grown from a niche experiment into one of the most significant bridges between traditional and on-chain finance: it brings an instrument with a century of institutional history into a format that settles in seconds, moves across borders without banks and can be used as collateral inside decentralized protocols. But the mechanics of how the yield flows, and — more importantly — who legally holds the underlying bills, determine whether a given token is a genuine claim on government debt or merely an IOU from a company promising to maintain one. Those mechanics are the subject of this deep dive.

What tokenized treasuries actually are

At the simplest level, a tokenized treasury product works like this: an issuer takes investor money, buys Treasury bills or invests in a fund holding them, and issues blockchain tokens representing claims on that portfolio. The tokens are typically transferable, programmable and — in most designs — redeemable for their share of the underlying portfolio’s value. The yield comes from the interest payments the US government makes on its debt, distributed to token holders either through an increasing token price, periodic distributions or daily accrual mechanisms, depending on the product’s architecture.

Three structural questions separate the products in this category, and each answer creates a different risk profile:

• What do the tokens represent legally? Some products give holders direct ownership of fund shares; others give a claim against the issuer’s balance sheet; still others issue debt instruments of the issuer itself. The difference matters most when something goes wrong, because bankruptcy law treats fund shares and unsecured claims very differently.
• Who holds the bills? The underlying securities may sit with a regulated custodian, inside a fund structure administered by an established asset manager, or — in the weakest designs — with the issuer itself, commingled with other assets.
• How is the yield distributed? Rebase tokens increase the holder’s balance daily; appreciating tokens rise in unit value against the underlying assets; distribution models pay out periodically. The differences are cosmetic for returns but matter for tax treatment and composability with other protocols.

What unites all of them is the yield source: Treasury bills currently maturing in weeks to months, paying interest that tracks the Federal Reserve’s policy rate. When policy rates are elevated, these products yield meaningfully; when rates fall, so does the yield — automatically and with no action from the issuer, because the underlying asset is the same one that moves every money market fund in existence.

Who holds the underlying bills: the custody chain

The question “who holds them” sounds simple, but in practice it traces a chain of legal entities whose quality determines the product’s safety. The chain typically runs from the token holder through several layers, and each layer adds both protection and a point of potential failure.

The typical custody structure, from token holder backward:

1. The token holder owns a blockchain token — a digital claim, which in most jurisdictions is not itself direct ownership of the Treasury security.
2. The issuer or token manager operates the product: collects subscriptions, mints and burns tokens, manages the on-chain mechanics. Its obligations depend on the legal wrapper — fund shares, debt instruments or balance-sheet claims.
3. The fund or SPV in well-structured products holds the actual portfolio of T-bills, ring-fenced from the issuer’s own assets; in weaker products, the issuer itself may hold the securities, blending them with its business.
4. The custodian bank holds the securities in custody — physically, in electronic form at the Fedwire system — in the name of the fund or the issuer. Regulated custody is the layer that makes the arrangement meaningful: without it, the token is a promise without collateral.
5. The asset manager (when present) invests the portfolio within defined mandates, often the same managers behind traditional money market funds.

The strongest products in this category — those issued in partnership with established asset managers and regulated custodians — replicate, in blockchain form, the structure of a conventional institutional money market fund. The weakest amount to unsecured corporate debt with a Treasury-inspired marketing narrative. Between those poles sits most of the market, and evaluating a specific product means identifying where in the chain the actual bills sit and what happens to the token if each layer above them fails.

How the yield flows: from Treasury coupon to token holder

Treasury bills themselves pay no periodic coupon; they are sold at a discount to face value and mature at par. A bill bought at 98 with a face value of 100 yields two points over its term — and tokenized products translate this mechanism into on-chain distributions in one of several ways. The mechanics matter because they affect how returns are received, taxed and reinvested.

The distribution models in use, and how each works:

• Appreciating tokens. The token’s redemption value increases as the portfolio accrues interest; holders realize yield on redemption or on transfers. This model suits DeFi composability, since the token price is predictable, but the accrued yield is unrealized until redemption.
• Rebasing tokens. The number of tokens in a holder’s wallet increases daily to reflect accrued interest. Returns are visible and automatic, but rebasing complicates integrations with protocols that assume fixed supply balances.
• Distribution tokens. Interest is paid out periodically in stablecoins or other assets, leaving the principal token value constant. This suits income-focused holders but requires active reinvestment to compound.

In all three cases, the gross yield before fees tracks the underlying Treasury rate closely; the differences between products appear in fees (management, minting, redemption), in the delay between minting and yield accrual, and in operational details such as minimum investment sizes and redemption timelines. Some products require KYC and restrict transferability to whitelisted addresses — a design that trades decentralization for regulatory compliance, and one that most institutional-oriented products have adopted.

Comparing the landscape: yield, access and risk

Because the underlying asset is identical across the category — short-term US government debt — the meaningful differences between products are structural rather than yield-related. The comparison below maps the main dimensions along which they vary.

Dimension	On-chain T-bill token	Traditional money market fund	Tokenized fund share	Stablecoin savings (DeFi)
Underlying asset	US T-bills or Treasury fund	T-bills, repos, commercial paper	Fund’s mandate (often T-bills)	Depends on protocol
Typical gross yield	Tracks policy rate	Tracks policy rate	Tracks policy rate	Varies with demand; can exceed or fall below
Settlement	Minutes, 24/7, global	One business day	Varies	Seconds
Regulatory wrapper	Fund, debt or SPV	Regulated fund	Regulated fund	Often none
Transfer restrictions	Often KYC-gated	Fully liquid, regulated	Often KYC-gated	None
Collateral usability on-chain	Growing, protocol-dependent	Not applicable	Limited	Broad
Primary risk	Issuer, custody, smart contract	Fund management	Issuer and fund	Smart contract, peg

Reading the table from left to right reveals the category’s actual value proposition: tokenized treasuries do not out-yield their traditional counterparts — they cannot, since they hold the same assets — but they move, settle and compose at blockchain speed. The value is in the plumbing, not the payout. A treasury token usable as collateral on a decentralized lending market, transferable across borders without banking hours, and settling in minutes rather than days is a genuinely new instrument, even though its yield formula is one of the oldest in finance.

Why the category grew: the forces behind the adoption

The growth of tokenized treasuries from a few hundred million dollars in assets to a multi-billion category was not driven by retail speculation — the users are overwhelmingly institutional. Understanding who holds these tokens and why clarifies both the demand and its durability:

• Crypto-native organizations parking treasury reserves. Companies, DAOs and funds holding significant stablecoin balances convert idle capital into yield-bearing treasuries, because a dollar sitting in a stablecoin earns nothing while the same dollar in a T-bill token earns the policy rate.
• Stablecoin issuers themselves. The largest stablecoin issuers hold the bulk of their reserves in short-term Treasuries and increasingly pass part of the interest through — making tokenized treasury exposure an extension of an already-established practice.
• Institutions seeking on-chain money markets. Asset managers, trading firms and funds use tokenized treasuries as operational cash: instant settlement, programmable transfers and collateral functionality that traditional accounts cannot offer.
• DeFi protocols integrating yield as collateral. Lending markets and derivatives venues list treasury tokens as collateral, effectively building money market funds into their risk models — a composability feature impossible with off-chain accounts.

This demand base explains the category’s resilience through crypto market cycles: the yield is not dependent on speculation, and the holders are not trading the tokens for appreciation. They are holding a money-market instrument that happens to live on a blockchain, and they hold it for exactly the reasons institutions have always held money market funds — with the added capabilities that tokenization enables.

The risks: what can go wrong and how to read it

Tokenized treasuries carry the credit risk of the US government — generally considered negligible — but the wrapper around that asset introduces risks of its own, and they are worth cataloging precisely because the product’s safety narrative can obscure them:

• Issuer and counterparty risk. If the token is a claim on the issuer rather than on the fund, the issuer’s failure threatens the holder regardless of the bills’ value. Reading the legal structure — fund share, SPV claim, or unsecured corporate debt — is the single most important piece of diligence.
• Custody risk. The custodian’s failure, insolvency or operational compromise affects the underlying assets; segregated, regulated custody materially reduces this, commingled custody does not.
• Smart contract risk. The token contract, the minting and burning logic and any bridging infrastructure are code, and code fails. Audit quality and incident history matter as much here as in any other on-chain product.
• Redemption and liquidity risk. Tokens are redeemable through the issuer’s process, not instantly at market; in stress conditions, redemption queues and gates are possible. A token that trades at a discount to NAV in panic conditions is functioning as designed — but holders should understand that secondary-market liquidity is thinner than the underlying asset’s.
• Regulatory risk. The category sits across two regulatory regimes, and its rules are still forming. Transfer restrictions, jurisdictional availability and reporting obligations vary between products and can change.
• Rate risk. The yield tracks the policy rate; when the Federal Reserve cuts, tokenized treasury yields fall mechanically. This is not a defect but a feature of the underlying asset — yet products marketed during high-rate periods attract expectations that may not survive a rate cycle.

None of these risks is unique to tokenization; each has a parallel in traditional finance. What is unique is that all of them are legible in public documentation for products that disclose their structures honestly — which makes the diligence process unusually straightforward for a category this young.

Who these products suit — and who they do not

The category’s fit depends on the user’s needs, and the honest answer divides the market into clear segments:

1. Well suited: holders of idle stablecoin balances. Anyone holding significant stablecoins for operational, treasury or liquidity purposes gains the policy rate on capital that otherwise earns nothing, without giving up the ability to move or deploy it quickly.
2. Well suited: institutions needing programmable money markets. Firms and protocols that want Treasury yield combined with instant settlement, smart contract functionality and cross-border transferability have no traditional equivalent to this capability.
3. Conditionally suited: yield-focused retail investors. Retail users can access some products, but the KYC requirements, minimum investments and legal wrappers often limit availability; for pure yield at retail scale, traditional Treasury funds remain simpler and cheaper.
4. Poorly suited: users seeking maximum yield. The category’s yields track government rates — a floor of safety and a ceiling of return. Anyone whose objective is above-market yield should look elsewhere, because the category’s design goal is precisely to avoid that trade-off.
5. Poorly suited: users needing anonymous, permissionless access. Most products require identity verification and restrict transfers; users prioritizing permissionlessness should understand that this category, by regulatory necessity, sits on the institutional side of that line.

The segment boundaries are worth respecting because they reflect the product’s design intent: tokenized treasuries are not trying to be everything for everyone. They are trying to be exactly one thing — a government money market instrument on-chain — and they serve the users who want that specific thing.

Conclusion

Tokenized treasuries are the rare crypto innovation whose yield requires no explanation of where it comes from: it is the interest the United States government pays on its own debt, passed through the token structure to the holder after fees. The yield tracks the Federal Reserve’s policy rate, rises and falls with it, and carries the credit profile of the issuer of the world’s benchmark risk-free asset. What tokenization adds is not return but form — instant settlement, global transferability, programmability and collateral usability that traditional Treasury accounts cannot provide.

The questions that matter in evaluating any specific product are the ones this category was created to answer: who legally holds the bills, in what structure, at what custodian, and what the token represents if any layer of that chain fails. Products built on regulated funds with segregated custody and established asset managers replicate institutional money market mechanics on-chain; products built on issuer promises with commingled assets are something else entirely, despite the shared vocabulary. For holders of idle stablecoins, for institutions needing on-chain cash management and for protocols integrating money markets into their infrastructure, the category offers a genuine capability that did not exist before. For users seeking exceptional returns, it offers a clear answer that the return is bounded by design — and that the safety of the underlying asset is the entire point. In a market where yield claims have historically outrun their sources, tokenized treasuries are notable for the opposite quality: a yield that says exactly what it is, backed by the most liquid debt instrument in existence, held by names that are usually disclosed. That transparency, more than any yield figure, is the category’s real innovation.
