Tokenized Treasuries: why on-chain dollars earn 4%

Tokenized U.S. Treasury funds held $14.65 billion in distributed value on October 26, 2026, across 120 products and 85,924 holders, according to RWA.xyz. The average seven-day yield across the category was 3.64 percent. That number is the whole pitch: dollars that behave like stablecoins, moving at block speed, sitting in wallets, while earning close to the policy rate, which the Federal Reserve set at a 3.75 to 4 percent target range on September 16, 2026.

A tokenized Treasury product is a legal wrapper plus a register. The wrapper is a fund, a note, or a partnership interest that actually buys Treasury bills or money-market exposure. The register is a blockchain that records who owns shares of it. You cannot hold a T-bill in an Ethereum wallet; you can hold a claim on a vehicle that holds T-bills, minted and redeemed against the wrapper, transferred between approved addresses. Everything good and everything risky about the category lives in that structure.

Why rates and crypto rails fit

The product-market fit is arithmetic. There are hundreds of billions of idle dollars in crypto: exchange balances, treasury war chests, market-maker inventory, DAO reserves. Held as stablecoins, those dollars earn nothing for the holder while the stablecoin issuer, per its own disclosures, earns float income on the reserve assets. A tokenized Treasury pays the holder the short end of the curve directly, net of a fee.

The rate backdrop helped. The Fed raised the target range a quarter point to 3.75 to 4 percent in September, its first increase since July 2023, and the yield on on-chain Treasury products tracks that band. RWA.xyz's category 7-day APY of 3.64 percent on October 26 is what's left of the 4 percent top of the range after fund expenses and wrapper costs. Gross policy rate in, net-of-fee yield out, with the plumbing open on Saturdays.

The rails add what brokers don't: 24/7 mint and redeem (Ondo advertises stablecoin in and out around the clock for OUSG), instant transfer between whitelisted parties, and collateral utility. USYC's entire raison d'etre, as Circle framed it when it acquired issuer Hashnote in January 2025, is to be yield-bearing collateral that converts to USDC at blockchain speed, at exchanges, custodians and prime brokers.

The players and their sizes

Per RWA.xyz on October 26, 2026, the leaderboard:

Product	Issuer	Distributed value	Notes
USDY	Ondo Finance	$2.37B	Secured note, non-U.S. persons, 12 networks
USYC	Circle (ex-Hashnote)	$2.37B	Cayman fund, BMA-licensed token administrator
BUIDL	BlackRock / Securitize	$2.17B	Money-market fund, institutional, whitelist-only
iBENJI + BENJI	Franklin Templeton	$1.71B + $0.68B	Suite was $1.98B in April 2026 per Franklin
JLTXX	J.P. Morgan / Kinexys	$0.79B	On-chain liquidity fund
WTGXX	WisdomTree	$0.76B	Treasury MMF

Two caveats on that table. RWA.xyz counts distributed value, only the token legs it tracks, so an issuer's reported AUM can run higher than the distributed figure. And OUSG, the Ondo fund for qualified purchasers (about $367 million per August 2026 reporting) is itself a wrapper over BUIDL: you hold a Delaware LP interest, and the LP holds BlackRock's token. The two older entrants from Backed Finance tell the opposite story: bIB01, a tokenized 0-1 year Treasury bond ETF, closed to new issuance in May 2025 and held about $19 million in market cap as of August 2026; Backed itself was bought by Kraken's parent Payward in December 2025, and Binance's bStocks line went after tokenized stocks rather than Treasuries. Early movers in this niche have a median lifespan shorter than a bond coupon.

The demand-side stat worth keeping: $14.65 billion divided by 85,924 holders averages about $170,000 per holder (my calculation from RWA.xyz's two figures). This is not retail parking spare change. It is a few thousand institutions and whales using regulated cash-management wrappers as on-chain cash.

How the yield actually reaches you

Two mechanics, both verified at the product level.

Accumulating: the token price rises and your balance doesn't. Ondo's own documentation walks through USDY and OUSG this way: 1,000 tokens at $1.00 become roughly $1.04 after a year at 4 percent. You realize yield by selling or redeeming. This plays well with DeFi, where a rising NAV is cleaner to account for than surprise rebases.

Distributing: the fund pays you in stablecoin. Franklin's BENJI distributes dividends on-chain every day of the year, including weekends and holidays, per Franklin's press release, a feature that only makes sense because the register itself is the blockchain.

Either way the money path is the same: T-bill coupon income flows to the fund, the fund nets expenses (OUSG lists a 3.70 percent APY against the 4 percent top of the Fed's range), and the residue shows up in token price or in stablecoin payments to your wallet.

The wrapper, cut open

Peel one and you find jurisdiction shopping. USYC is a share of a Cayman Islands mutual fund, administered by Circle International Bermuda Limited under a Bermuda Monetary Authority license. OUSG is a Delaware limited partnership interest sold under a private-placement exemption to accredited investors and qualified purchasers, with eligibility enforced on-chain: a non-whitelisted wallet cannot even receive the token in a secondary transfer. USDY points the other way, a secured note issued by a bankruptcy-remote vehicle backed by short-term Treasuries and bank demand deposits, open to eligible non-U.S. persons at low minimums but closed to U.S. retail. BUIDL is a U.S. fund tokenized by Securitize with pre-approved investors only.

Read together: the "same" product, T-bills in a token, runs under at least four legal regimes with four different answers to the question that matters, what happens to me if the issuer fails. The blockchain part is the least variable piece of that puzzle.

Where it can break

Rate risk is the polite one. Yields track the policy rate down as easily as up. OUSG advertises a 3.76 percent seven-day yield on a day when the Fed's range tops out at 4 percent; when the next easing cycle starts, the token yield follows the funds rate within a coupon period, and there is no lockup to complain about.

Redemption friction is the real one. Instant redeem has fine print: OUSG caps daily instant mints and redemptions, and amounts above the cap fall back to non-instant requests handled by email. Whitelisting means exit liquidity depends on the issuer keeping the onboarding desk open. In stress, a gate is a paragraph in a terms document, not a smart-contract event you can watch on-chain.

Counterparty risk is the one tokenization does not remove. The T-bills sit with a custodian. The register runs on an issuer's or transfer agent's infrastructure. The token can be frozen by design, because an AML-compliant fund could not be anything else. None of that is exotic, but it inverts the crypto instinct: here the private key protects you from third parties, not from the issuer.

Then there is concentration risk in the plumbing: OUSG holds most of its book in BUIDL, so Ondo holders are BlackRock holders twice over. Wrappers over wrappers are how yield chains grow and how they fail in sequence.

Scale, honestly

The treasury segment is the institutional anchor of the RWA category: $14.65 billion distributed on RWA.xyz against $39.01 billion for all tokenized assets excluding stablecoins, same date. The scale is real but not monotonic: RWA.xyz's 30-day change on the Treasury segment sits near zero, +0.08 percent, so the early-2026 ramp has gone quiet. At 86,000 holders and $170,000 average ticket, the story so far is banks, funds and market-makers replacing prime-brokerage cash with a better register, not the world tokenizing its checking accounts. Whether retail ever gets a version of these products under terms it will actually read is the open question, and the answer will be set by regulators, not by yield.
