Tokenized Treasuries: How They Work and What to Watch 2026
Tokenized treasuries are the largest and most institutionally engaged category in on-chain real-world assets. A tokenized treasury is a blockchain token representing a share of a fund that holds short-duration US government debt. You get on-chain access to Treasury yield, with movement and settlement that happen 24/7 instead of through traditional market plumbing.
The growth has been steep and measurable. Tokenized U.S. Treasury products crossed $15.9 billion in on-chain assets under management as of September 2026, up from $6.5 billion a year ago and less than $1 billion in early 2024. The market reached $15.35 billion in May 2026, and by September the figure expanded to approximately $15.9 billion, a 144% increase from July 2025. RWTS doesn't cheerlead that number. We're the credit-rating agency for tokenized real assets. We rate, you decide. Here is how the category actually works, and what the AUM headline leaves out.
Where does tokenized treasury yield come from?
The yield is not a crypto-native return. It is the US short end, passed through on-chain. A tokenized treasury fund generates yield by holding a portfolio of US Treasury bills, overnight repurchase agreements, and operating cash. Interest accrues daily and is distributed either as new tokens or through a rising token price. The benchmark most products target is the secured overnight financing rate.
That means the yield case is straightforward, and conditional. When the US short end sits in the 4–5% band, tokenized treasuries capture close to that rate, minus a management fee, without you leaving the stablecoin rails you already use. If the Fed cuts aggressively, that yield falls in lockstep, because the mechanism is pass-through, not a spread the issuer manufactures. The variable to watch is the Fed dot-plot, not the marketing.
The two accrual models
Products split into two designs, and the difference matters for tax and collateral use. Some hold a stable $1 price and pay yield as new tokens; others let the token price rise. BUIDL uses a value-accrual model where the token price increases daily to reflect accrued yield, if you hold 100 BUIDL for a year at 5% yield, you have 100 tokens worth $105, with no new tokens distributed.
The rebasing versus value-accrual choice tracks your use case. For DAO treasuries and DeFi protocol reserves that need stable $1.00 collateral, rebasing funds win. For individual investors focused on tax efficiency and long-term yield accumulation, yield-bearing tokens have the edge.
Who actually holds these
Demand is institutional, not retail. Stablecoin issuers represent a significant portion of inflows, as they seek to generate yield on the massive reserves backing their tokens. DeFi protocols have become major participants, using tokenized treasuries as collateral and liquidity backstops. Corporate treasuries from both crypto-native and traditional enterprises are increasingly allocating capital as part of cash management.
Concentration is high. Growth concentrated in a handful of products. BUIDL alone added roughly $2B over the twelve months ending May 2026. Hashnote's USYC scaled from a few hundred million to $3B once Circle integrated it into stablecoin redemption flows. A category this concentrated inherits the operational risk of a few issuers, a point our Trust Score methodology weighs directly.
Are tokenized treasuries safe?
Verdict: the underlying assets are among the safest in finance, but the token layer adds risk the T-bills themselves never carried. RWTS scores the leaders in Tier 2, and the spread tells the story: BUIDL at T2 (84/100), USYC and USDY at T2 (81/100), and OUSG at T2 (77/100). None reaches Tier 1.
The gap between a Treasury bill and a token wrapping it is smart-contract risk, custody arrangements, and wrapper opacity. OUSG illustrates the layering. The majority of OUSG's assets are invested in BlackRock's BUIDL, giving it indirect exposure to BUIDL's underlying Treasury strategy with a slightly different access structure. That indirection is convenient, but it also stacks one issuer's operational risk on top of another's, the kind of structural detail that separates a 77 from an 84.
Can US retail investors buy them?
Mostly not directly. The largest names are gated. Tokenized treasuries by mid-2026 sit as the largest and most institutionally engaged category in the RWA market, with BUIDL, BENJI, OUSG, USDY and Superstate USTB accounting for the bulk of AUM at the institutional and accredited tier. Retail access concentrates in USDY, BENJI's chain wrappers, and Backed Finance's bToken range, each with different access matrices, minimums, and regulatory framings. The honest qualifications are jurisdictional and structural: most retail-friendly products exclude US persons, and primary-rail redemption is fast while secondary liquidity is thin.
The bottom line
Tokenized treasuries are real infrastructure now, not a pitch. But "on-chain" doesn't upgrade the credit, it changes the plumbing and adds a token-layer risk you have to price. If you want the product-by-product breakdown, our tokenized treasuries comparison hub carries every score. And if you're weighing a tokenized fund against holding a yield-bearing stablecoin instead, our analysis of USDC yield and how much you can earn covers the trade-off. We rate. You decide.
