Tokenized Treasuries Cross $13.4B: USYC Overtakes BUIDL as Issuer Competition Heats Up

The tokenized U.S. Treasury market passed a meaningful threshold in early April 2026, with total on-chain value reaching approximately $13.4 billion, up from roughly $10 billion in late February, according to data aggregated in RedStone's 2026 Tokenization & RWA Standards Report. Tokenized Treasuries are now the single largest and fastest-growing tokenized asset class, excluding stablecoins. More interesting than the headline growth, however, is what is happening at the top of the leaderboard: the hierarchy has shifted, and issuer competition is driving real product differentiation for the first time.

For investors allocating to this segment, the "just buy BUIDL" default answer is no longer automatic. This piece breaks down the current landscape, the competitive dynamics reshaping it, and where yield-focused allocators should actually look.

The Current Leaderboard

Per the latest Q1 2026 data:

Circle's USYC sits at roughly $2.7 billion in tokenized value, making it the largest single tokenized Treasury product.

BlackRock's BUIDL is at approximately $2.4 billion, having been overtaken earlier this year. This order (USYC ahead of BUIDL) represents a reversal of the ranking that held through most of 2025.

Ondo Finance's suite (which includes OUSG, USDY, and related products) totals approximately $2.6 billion. Ondo's permissionless USDY alone crossed $1 billion in early 2026 and is now live across nine blockchains.

Franklin Templeton's BENJI is at roughly $1.0 billion. WisdomTree's WTGXX rounds out the top five at approximately $861 million.

Those are the verified data points. Everything below them in the stack is smaller, less liquid, and less institutionally anchored.

Risk First: What These Products Actually Are

Before discussing yields, the important caveat. Tokenized Treasury products are not uniform. They differ in:

Underlying holdings. Most hold short-duration U.S. Treasury bills directly; some hold Treasury money market funds; some hold repo. Duration risk is low across the category but not identical.

Access model. BUIDL is permissioned and restricted to qualified institutional buyers. USYC operates as an institutional-grade product but has expanded distribution partnerships. USDY is permissionless for non-U.S. investors. BENJI and WTGXX sit in between with registered-fund wrappers.

Redemption mechanics: Some products support same-day redemption; others settle T+1 or longer. In stressed markets, these differences matter enormously.

Chain availability: USDY spans nine chains. BUIDL is expanding but historically more limited. Chain choice affects counterparty risk at the bridge layer.

Headline APY figures for all of these products track the short end of the Treasury curve; currently offering yields broadly in the 4–4.3% range given the federal funds target at 3.50–3.75% and the 10-year at 4.33% per recent FOMC data. The yield differentiation across products is smaller than the structural differences between them.

Why USYC Overtook BUIDL

Three factors explain the shift.

First, distribution. Circle has aggressively expanded USYC's reach through exchange and custodian integrations. Circle's existing USDC infrastructure gives USYC a pre-built distribution rail into wallets, custodians, and trading venues that BlackRock, as a traditional asset manager, does not have at the same depth.

Second, product flexibility. USYC has been positioned as a composable institutional money market, with easier conversion between USDC and USYC. BUIDL, while sophisticated, was built with a more conservative wrapper that has been slower to integrate into collateral systems across DeFi.

Third, BlackRock's partnership push. BlackRock's announced Uniswap integration (making BUIDL shares tradeable via UniswapX) is a defensive move designed to broaden access. It has not yet fully closed the gap.

None of this implies BUIDL is a weaker product in absolute terms. BlackRock's custodial reputation and operational rigor remain category-leading. What has shifted is the market's willingness to use a competitor when that competitor is more technically accessible.

What This Means for Yield Seekers

Three practical implications.

Yield parity, structural divergence: Because all five major products track short-duration Treasuries, headline APY differences are typically within 10–20 basis points. The real decision variable is not yield; it is access, composability, and downstream deployment.

For U.S. qualified institutions: BUIDL and USYC are both credible. USYC's recent momentum and integration depth suggest it is becoming the operational default. BUIDL remains the conservative choice and the product most likely to satisfy the strictest compliance mandates.

For non-U.S. investors: USDY remains the most permissive product with the broadest chain availability, trading modest yield for far greater accessibility and composability. USDY's growth ($1 billion in TVL standalone, nine chains live) indicates real demand for a tokenized-treasury-backed instrument that can move freely across DeFi.

For DeFi-native allocators: The composability story is where product differentiation matters most. A tokenized Treasury token that can be used as collateral on Morpho, deposited into a Kamino vault on Solana, or paired against USDC on Uniswap has materially more utility than one that cannot. USDY and the emerging USYC integrations lead here; BUIDL is catching up via the Uniswap partnership.

Risk Factors to Track

For any tokenized Treasury allocation, three monitoring priorities:

Redemption mechanics under stress. The October 2025 market event compressed yields across DeFi and pressured some tokenized-asset redemption queues. Any allocator should stress-test how their product of choice behaved during that window.

Custodian concentration. Most tokenized Treasuries sit with a small number of qualified custodians. A custodian-level operational issue would impact multiple issuers simultaneously. This is a tail risk, not a base case, but it is real.

Regulatory evolution. Tokenized Treasuries sit in a regulatory grey zone that U.S. regulators have partially clarified but not fully codified. Product structures that depend on specific regulatory interpretations carry policy risk. Non-U.S. investors in USDY face a meaningfully different regulatory perimeter than U.S. investors in BUIDL or BENJI.

The BIS Effect

One data point worth flagging for context. Bank for International Settlements (BIS) research has estimated that a $3.5 billion stablecoin inflow reduces Treasury bill yields by roughly 2.5–5 basis points. Tokenized Treasuries are now at $13.4 billion and growing quickly. The sector is starting to meaningfully influence the short end of the Treasury curve it feeds on. This is a subtle but important macro-feedback loop: if tokenized Treasuries continue compounding, they become a price-making force in the underlying market, not just a price-taker.

For allocators, this means the "risk-free rate" embedded in these tokens may itself be partly shaped by how much capital flows into tokens like USYC and BUIDL. The yield is attractive today; the structural question is whether it can remain attractive at substantially higher AUM.

RWTS Trust Scores: How These Products Compare

RWTS rates every tokenized treasury product using our six-dimension Trust Score framework. Here is how the major issuers compare:

| Asset | Trust Score | Tier | Backing | Verification | Redeemability | |-------|-----------|------|---------|-------------|--------------| | BUIDL | 88/100 | T2 | 22/25 | 18/20 | 13/15 | | USYC | 83/100 | T2 | 21/25 | 17/20 | 12/15 | | USDY | 83/100 | T2 | 21/25 | 16/20 | 12/15 | | OUSG | 80/100 | T2 | 20/25 | 16/20 | 11/15 | | USTB | 78/100 | T2 | 19/25 | 16/20 | 11/15 | | tbill | 80/100 | T2 | 20/25 | 16/20 | 12/15 |

All products in this category receive Tier 2 (Treasury & Fiat-Backed) classification. BUIDL leads on Trust Score primarily due to stronger asset backing verification and BlackRock's institutional infrastructure.

Bottom Line

Tokenized Treasuries are the largest, fastest-growing, and most institutionally credible category of on-chain RWAs. The $13.4 billion milestone is real, and the competitive reshuffling (USYC overtaking BUIDL, Ondo building a multi-product suite, BlackRock partnering with Uniswap) indicates the category has moved past single-provider dominance into genuine competitive dynamics.

For yield seekers: do not overindex on headline APY. Choose based on access (U.S. vs. non-U.S., institutional vs. permissionless); composability (chains supported, DeFi integrations); and redemption mechanics. Stress-test your holdings against past market dislocations, and monitor the custodian and regulatory concentration risks that sit beneath every product in this category.

The tokenized Treasury trade is no longer a debate about whether the category works. It is a question of which issuer best matches your operational constraints. The RWTS asset directory tracks current USYC, BUIDL, USDY, BENJI, and WTGXX yields, chain coverage, and access models side by side.
