Why people are comparing these two products at all
For most of the last fifty years, a yield-seeking saver who wanted exposure to short-dated US government debt had a simple menu: a bank savings account, a broker's sweep, or a money market fund. The product was dull, the contract was clear, and the only real choice was which sponsor to trust with the cash.
From around 2023 onward, a parallel set of products appeared on public blockchains, marketed under the label "tokenized Treasuries." Funds such as BUIDL (BlackRock via Securitize), OUSG (Ondo), USDY (Ondo), USYC (Circle's Hashnote subsidiary), USTB (Superstate), and JTRSY (Janus Henderson/Ankura) all offer tokenized shares of vehicles that ultimately own Treasury bills, repo, or bank deposits.
The appeal is obvious on the surface: a yield that, in normal conditions, sits in the 4% to 5.5% range, accessible 24/7 from a self-custody wallet, and usable as collateral inside DeFi. Readers who already hold ETH or stablecoins and do not want to wire cash to a US broker see this as a way to put idle balances to work without leaving the crypto stack.
But "tokenized Treasury" is a marketing term, not a legal one. The funds behind the tokens have very different regulatory structures, redemption rules, and counterparty chains, and several of them are structured outside the US, which changes who can invest and what protections apply. Before chasing the yield, it is worth understanding what is actually inside the wrapper.
Where the yield actually comes from, and where NAV risk lives
Both tokenized Treasuries and traditional money market funds generate the vast majority of their yield from the same underlying instruments: US Treasury bills, notes with short duration, overnight reverse repurchase agreements, and, in some cases, short-dated commercial paper or bank deposits. The Federal Reserve's policy rate, plus the shape of the front-end of the Treasury curve, drives both. When the Fed cuts, both fall; when the Fed hikes, both rise.
The first real difference is duration. A standard US 2a-7 money market fund must hold at least 50% of assets in securities maturing within seven days and maintain a weighted average maturity of 60 days or less. That is why a Vanguard Federal Money Market or a JPMorgan Prime MMF barely moves when the curve shifts. A tokenized fund that holds individual T-bills to maturity, or that wraps longer-dated repo, can show small NAV drift between issuance and redemption. Most of the time this is invisible. During a rate shock, it is not.
The second difference is the credit stack under the yield. A 2a-7 government MMF holds US Treasuries and reverse repo backed by Treasuries; that is roughly the safest short-term credit in the world. A tokenized Treasury product can do the same, but it can also layer in bank deposits, commercial paper, or non-Treasury collateral, depending on the prospectus. USYC, for example, is structured as a Cayman fund holding short-dated US government obligations plus USDC reserve income, which adds Circle as a credit dependency. OUSG holds Treasuries and reverse repo through Clear Street as intermediary. Reading the prospectus is not optional.
Finally, NAV risk itself behaves differently. A 2a-7 MMF is required to use amortized cost accounting and a stable NAV of $1.00, with the option of "breaking the buck" only in extreme stress (the 2008 Reserve Primary fund episode is the canonical example). A tokenized fund typically marks to market and issues tokens whose on-chain value floats with the underlying securities. That is more honest, but it also means the token's dollar price is not guaranteed to be one dollar at all times.
Redemption terms: instant stablecoin, T+1, or something in between
This is the section most marketing material glosses over, and where the real friction lives. A Fidelity Government MMF or a JPMorgan Prime MMF settles at T+1 or T+2 to your brokerage account, same as selling a stock. There is no smart contract, no oracle, and no token to redeem. The only friction is the banking system.
Tokenized Treasury products split into three groups. The first group offers near-instant redemption in stablecoins for large qualified investors who pass KYC. BUIDL, issued by Securitize on behalf of BlackRock, lets authorized participants redeem daily for USDC through a banking partner, with the actual token transfer on Ethereum settling in minutes once the off-chain leg clears. OUSG and USDY from Ondo follow a similar model for non-US investors, with redemption windows that depend on the holder's tier and the day's flow.
The second group offers a longer queue. USYC, which targets accredited and offshore investors, historically required a multi-day redemption process. JTRSY, the Janus Henderson product distributed via Ankura, operates on a subscription/redemption cycle of one or more business days. These are not slow by traditional standards, but they are not the "cash in three seconds" experience that some crypto marketing implies.
The third group is closer to a traditional MMF. Superstate's USTB, for example, is structured as a Delaware statutory trust holding short-dated Treasuries and lets US-eligible investors redeem with a normal banking settlement. The token is on-chain, but the redemption is a T+1 or T+2 wire. In practice, that means USTB is best treated as a treasury-management tool, not a 24/7 liquidity token.
The practical question for a reader is simple: when you click "redeem," are you getting USDC in your wallet in under an hour, a stablecoin the next business day, or a bank wire two days later? Each of those answers maps to a different product, and each has a different operational risk if markets are stressed and everyone tries to exit at once.
Counterparty chain: who actually holds the bonds
With a money market fund, the chain is short and well-rehearsed. You hold shares of a registered investment company. The fund's assets sit at a custodian, typically a large US bank. The transfer agent keeps the shareholder register. A board oversees the manager. NAV is struck daily by an administrator. If the fund fails, the custodian's books tell the bankruptcy court exactly who owns what.
A tokenized Treasury product is, structurally, more like a closed-end fund or a structured note than a 2a-7 MMF. The chain typically runs: an SPV or trust (often Cayman, BVI, or Delaware) owns the underlying securities; a custodian (BNY Mellon, Clear Street, Anchorage Digital, BitGo, or similar) holds the bonds; a transfer agent (Securitize, Hashnote, or a fund administrator) records token holders; the token itself is issued on a public chain (Ethereum, Solana, or a permissioned chain) and may be wrapped or bridged to other networks for DeFi use.
Each link is a counterparty. The token holder is not a shareholder of a registered investment company in most cases; they are a beneficial owner of an SPV, or even just a holder of a token whose legal claim depends on the issuer's terms. The strongest cases, like BUIDL, use a 40-Act-style fund structure with a US-registered advisor and a Tier-1 custodian, which is materially closer to a traditional MMF. The weakest cases rely on an offshore issuer, a non-US custodian, and a token that is only as good as the issuer's willingness to honor redemptions.
This is also where jurisdiction matters. Many tokenized Treasury products explicitly exclude US persons from the main share class to avoid registering under the Investment Company Act. US investors who access them through feeder structures or non-US entities are taking on additional tax, reporting, and enforcement risk that a simple MMF does not impose.
Regulatory regime: 40-Act fund vs offshore SPV
The legal wrapper is the single biggest determinant of what protections you actually have. A US 2a-7 money market fund is regulated under the Investment Company Act of 1940, subject to SEC oversight, required to file prospectuses and periodic reports, and held to strict rules on liquidity, duration, and NAV stability. The SEC also imposed sweeping reforms after the 2020 COVID dash-for-cash, including redemption gates, liquidity fees, and a move toward a "prime" vs "government" distinction.
Tokenized Treasury products split across at least three regulatory buckets. BUIDL sits in a registered fund structure advised by BlackRock, with Securitize acting as transfer agent and tokenization platform. USTB is a Delaware trust that files as a public reporting company. OUSG, USDY, USYC, and most of the rest are Cayman or BVI vehicles that rely on offshore exemptions (typically restricted to non-US or accredited investors) and are not subject to the 40-Act framework at all.
For a US retail investor, that difference is not academic. An offshore SPV may offer a higher headline yield because it can hold assets or use leverage that a 2a-7 fund cannot, but the investor's recourse in a dispute is foreign, the disclosure regime is lighter, and the tax treatment can be unfavorable. A 40-Act fund or a US-registered trust offers the opposite: lower headline yield, much stronger disclosure, and a familiar legal backstop.
The other regulatory axis is the token itself. Issuers must navigate securities laws in the US, EU, Singapore, and elsewhere, and the way they choose to do that (Reg D, Reg S, MiCA-compliant EU distribution, or simply geo-blocking US persons) tells you a lot about how seriously they take compliance.
On-chain composability vs off-chain simplicity
This is the one dimension on which tokenized Treasuries genuinely offer something a money market fund does not. A tokenized Treasury token can, in principle, be used as collateral on a lending market, supplied to a liquidity pool, posted to a perpetual exchange as margin, or routed through a smart contract that automates a treasury strategy. A share of a Fidelity MMF cannot.
That composability is the reason institutional desks and DAOs hold products like BUIDL or OUSG. It is also the source of new risks that have no analog in the off-chain world:
- Smart-contract risk. The token itself, the mint/burn contract, the registry contract, and any wrapper or bridge code are all attack surfaces. A bug in any of them can freeze or drain assets.
- Bridge risk. Many tokenized Treasury tokens are bridged from Ethereum to other chains to access DeFi liquidity. Bridge exploits have been among the largest losses in crypto history.
- Oracle risk. If a DeFi protocol uses a tokenized Treasury token as collateral, it usually relies on a price oracle to value it. Oracle manipulation or staleness can lead to bad debt.
- Custody risk in DeFi. Supplying the token to a lending market means trusting the market's contracts, its governance token holders, and its liquidation engine. None of that exists in a brokerage MMF.
The honest framing is that composability is a feature, but it is a feature you pay for in additional risk. A reader who simply wants a safe place to park cash for six months does not need composability and would be better served by a plain MMF. A reader who needs programmable, 24/7, cross-chain liquidity to run an on-chain treasury has a real reason to use a tokenized product and should size accordingly.
Practical implications for a yield-seeking reader
Step one is to separate the use case from the marketing. If the goal is to earn yield on idle cash and the money is not needed for on-chain activity, a US-registered money market fund at a low-cost broker is hard to beat on safety, simplicity, tax reporting, and FDIC or stable-NAV protections. The yield will be within a few dozen basis points of any tokenized product, and the operational risk is a fraction of the on-chain version.
Step two is to define the on-chain need. If the use case is collateral for borrowing, margin on a perp DEX, or working capital for a DAO or protocol, then a tokenized Treasury is one of the few ways to get short-dated government exposure without leaving the wallet. In that case, prefer products with the strongest legal wrappers (BUIDL and USTB for US investors; OUSG and USDY for non-US investors), Tier-1 custodians, daily disclosed NAV, and audited code.
Step three is to read the redemption mechanics for the specific token. Check the minimum redemption size, the cutoff time, whether redemptions are in stablecoin or fiat, and whether the token supports instant transfer or only end-of-day settlement. Check what happens during a redemption gate: most issuers reserve the right to suspend redemptions in extreme conditions, just like a 2a-7 fund.
Step four is to size for failure. Smart-contract bugs, custodian failures, and offshore-issuer disputes are not theoretical; the crypto industry has lost tens of billions of dollars to each. Treat the on-chain portion of a treasury as risk capital and keep the bulk of savings in instruments with centuries of legal precedent, not months.
Read tokenized Treasuries critically with Zippfeed
Tokenized Treasuries, money market funds, and the broader RWA category move quickly, and the gap between marketing and mechanics is wider than in almost any other corner of crypto. Zippfeed tracks the headlines that actually move BUIDL, OUSG, USDY, USYC, USTB, and JTRSY, tags each story as bullish, neutral, or bearish, and rates it by importance, so you can separate issuer announcements, regulatory shifts, and DeFi integrations from background noise and act on the ones that matter.
