"The fund is evolving from a yield-bearing token into a core component of crypto market infrastructure." — Carlos Domingo, CEO, Securitize
Tokenized U.S. Treasury products have 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 category now spans 76 distinct products, approximately 58,600 on-chain holders, and six major blockchains.
What began as a passive yield vehicle for crypto-native treasuries has become an active collateral layer for institutional derivatives, DeFi lending markets, and exchange margin systems. Circle's USYC leads with approximately $3 billion in AUM after its integration as off-exchange collateral on Binance, followed by BlackRock's BUIDL at $2.9 billion across six chains. The shift from static yield product to programmable financial primitive is the defining characteristic of tokenized Treasuries in 2026 — and the primary reason the market has more than doubled in twelve months.
The competitive dynamics are no longer about yield spread or credit quality — the underlying asset is the same U.S. Treasury bill across all products. The race is about distribution infrastructure: which fund can plug into the most trading venues, lending protocols, and custody platforms. Distribution, not manufacturing, is the bottleneck.
The tokenized U.S. Treasury market reached $15.35 billion in May 2026, topping the previous mid-April peak of $15.10 billion, according to rwa.xyz tracking data. By September 2026, the figure has expanded to approximately $15.9 billion. This represents a 144% increase from the $6.51 billion recorded on July 20, 2025.
The market is distributed across 76 products and approximately 58,600 holders, with a weighted average 7-day APY of 3.36% as of May 2026. The top five issuers — Circle (USYC), BlackRock (BUIDL), Ondo Finance (USDY), Franklin Templeton (BENJI), and Centrifuge (JTRSY) — account for the majority of AUM.
The broader on-chain real-world asset category, excluding stablecoins, crossed $32 billion in May 2026, a gain of more than 200% over the prior year, according to Crypto Briefing. Tokenized Treasuries represent roughly half of that total, making government debt the single largest RWA category on-chain.
Growth has been institutional rather than retail. In 2023, most tokenized RWA AUM was held by DAOs and crypto-native treasuries seeking yield alternatives to idle stablecoin balances. By 2026, the holder base includes corporate treasuries, family offices, fintech platforms, and a small but growing segment of regulated allocators using tokenized funds as settlement primitives.
Circle USYC — ~$3B AUM. Circle entered the tokenized fund market after acquiring Hashnote, the issuer of USYC, in early 2025. USYC overtook BlackRock's BUIDL as the largest tokenized Treasury product in March 2026, when the total market hit $11 billion, according to CoinDesk. The catalyst was mechanical: Binance introduced USYC as off-exchange collateral for institutional derivatives trading on BNB Chain in July 2025. Supply on BNB Chain alone swelled to $1.84 billion. The integration uses Binance Banking Triparty and Ceffu, Binance's institutional custody platform, to hold collateral.
BlackRock BUIDL — ~$2.9B AUM. Issued through Securitize, BUIDL crossed $5 billion in total AUM in July 2026, according to CryptoxInsights, though active on-chain supply measured by rwa.xyz sits lower at approximately $2.9 billion. The discrepancy reflects differing methodologies — some trackers count wrapped and redeemed shares differently. BUIDL is live on Ethereum, Aptos, Arbitrum, Avalanche, Optimism, and Polygon. It invests exclusively in cash, U.S. Treasury bills, and repo agreements, paying daily accrued dividends on-chain. Transfers are restricted to whitelisted addresses, which limits open DeFi composability but aligns with institutional compliance requirements.
Ondo USDY — ~$2.1B AUM. USDY is the most chain-distributed of the major products, available across eight chains. It targets non-U.S. retail buyers with no minimum subscription and trades on whitelisted secondary markets. Ondo saw $1.4 billion in net USDY inflows during H1 2026. Total Ondo platform AUM, including its OUSG and tokenized equities products, reached $3.43 billion.
Franklin Templeton BENJI — ~$2.5B AUM. BENJI tokenizes Franklin Templeton's FOBXX money market fund, a U.S.-registered '40 Act mutual fund. This structural distinction matters: entities with legal or auditor restrictions against holding private fund vehicles — corporates, foundations, public agencies — can hold mutual fund shares but cannot hold a Cayman or BVI private fund interest. BENJI grew from $594 million in January 2026 to over $2.5 billion by July, according to Crypto Briefing, representing more than 100% year-to-date growth. A partnership with DigiFT in May 2026 targets Asian investor accessibility; a subsequent MoonPay Trade integration enables stablecoin-to-BENJI swaps.
The defining development of 2026 is the transition from tokenized Treasuries as yield instruments to tokenized Treasuries as collateral instruments. The economic proposition is straightforward: a trading desk that posts a tokenized Treasury as margin continues earning approximately 3.3–5.25% APY on the underlying T-bill while the same token simultaneously serves as collateral for derivatives, lending, or borrowing positions.
This dual-use characteristic — earning yield while doing collateral duty — cannot be replicated by traditional money market funds, which require redemption before the capital can be redeployed. The tokenized version collapses two steps into one.
Three primary collateral use cases have emerged:
Exchange margin. Circle's USYC as off-exchange collateral on Binance is the highest-volume implementation. Institutional derivatives traders post USYC instead of USDC or fiat, maintaining yield exposure on idle margin.
DeFi lending collateral. Protocols including Aave (via its Horizon RWA market), Morpho, and Euler now accept tokenized Treasury tokens as collateral for borrowing stablecoins. Sky (formerly MakerDAO) holds over $2 billion in RWA collateral, with BUIDL among the primary assets.
DAO treasury reserves. DAOs allocate idle treasury funds to tokenized Treasuries as yield-bearing reserve assets, replacing unproductive stablecoin holdings.
The integration of tokenized Treasuries into DeFi lending is proceeding along two architectural tracks.
Permissioned pools. Aave's Horizon platform operates as an isolated, permissioned market for institutional users. VanEck's VBILL tokenized Treasury fund went live on Horizon in late 2025, powered by Chainlink's NAVLink oracle for on-chain NAV pricing. Since launch, Horizon has grown to over $460 million in total market size. In May 2026, VanEck extended VBILL to Euler, a permissionless lending protocol, expanding its DeFi footprint.
Curated vaults. Morpho's architecture enables curated lending markets where an institutional lender can create a vault that accepts only specified collateral types — tokenized Treasuries and wstETH, for example — without requiring protocol-level governance votes for each new asset listing.
Sky/MakerDAO. Sky holds the largest single DeFi allocation to tokenized Treasuries at over $2 billion, using them as backing collateral for DAI issuance. This represents an evolution from Sky's earlier reliance on crypto-native collateral and marks one of the largest single-entity deployments of tokenized government debt in DeFi.
The composability ceiling for BUIDL remains constrained by its whitelisted transfer model: tokens cannot circulate freely in permissionless pools. USYC and USDY, by contrast, trade on secondary markets within whitelisted jurisdictions, offering greater DeFi composability at the cost of more complex regulatory exposure.
The regulatory framework around tokenized Treasuries sits at a different maturity level than broader crypto regulation. Several structural advantages apply:
Fund registration. BENJI's '40 Act registration provides a familiar compliance wrapper for U.S.-domiciled institutional buyers. BUIDL operates as a BVI-domiciled fund with SEC-registered Securitize as transfer agent. The SEC cleared the path for Franklin Templeton funds to hold tokenized BENJI shares, according to BigGo Finance reporting.
Securitize NYSE listing. Securitize debuted on the NYSE on July 2, 2026 under ticker SECZ — the first pure-play tokenization firm to list on a major U.S. exchange. CEO Carlos Domingo stated the company would pursue acquisitions with a $400 million balance sheet, according to CoinDesk.
GENIUS Act interaction. The pending stablecoin legislation draws a line between payment stablecoins and yield-bearing instruments. Tokenized Treasuries fall on the yield side of this divide, potentially requiring different licensing frameworks depending on final bill language.
BlackRock's strategic framing. In his 2026 annual letter, BlackRock CEO Larry Fink stated that tokenization is "the next generation for markets," comparing blockchain-based assets to the internet's early impact on information access. BlackRock manages nearly $14 trillion in total assets and holds close to $150 billion linked to digital markets.
Several risks merit attention:
Yield compression. As of September 2026, the weighted average 7-day APY across tokenized Treasury products stands at approximately 3.36%. Should the Fed proceed with further rate adjustments, yield differentials between on-chain Treasuries and traditional money market alternatives may narrow, potentially reducing the incentive for institutional migration.
Concentration risk. Five issuers control the vast majority of the $15.9 billion market. A custody failure, smart contract exploit, or regulatory action affecting any single issuer could cascade across DeFi protocols that accept its tokens as collateral.
Redemption mechanics. Most tokenized Treasury products offer T+0 or T+1 redemption under normal conditions. Stress scenarios — a liquidity crunch, oracle failure, or mass redemption event — have not been tested at the current AUM scale.
Regulatory fragmentation. USDY serves non-U.S. markets; BENJI targets U.S. registered fund buyers; BUIDL restricts to whitelisted addresses. No single product has achieved global regulatory clearance, creating a fragmented landscape that limits unified market depth.
Oracle dependency. On-chain NAV pricing for lending collateral relies on oracle infrastructure, primarily Chainlink NAVLink. Oracle failure or manipulation would directly affect collateral valuations and liquidation thresholds.
The tokenized Treasury market has moved past the proof-of-concept phase. At $15.9 billion, it is large enough to function as a distinct asset class within on-chain capital markets. The transition from yield instrument to collateral primitive represents a structural shift: institutions no longer park cash in tokenized Treasuries merely for yield. They use them simultaneously as margin, lending collateral, and treasury reserves, collapsing multiple balance sheet functions into a single on-chain position.
The competitive landscape increasingly resembles traditional fund distribution — the asset is commoditized (U.S. T-bills), so the fight is over rails, integrations, and compliance wrappers. Circle's exchange collateral strategy, BlackRock's multi-chain whitelisted model, Ondo's retail-accessible cross-chain approach, and Franklin Templeton's registered fund structure each represent distinct distribution bets.
Whether this market reaches the $100 billion projections cited by some analysts depends on factors largely outside the crypto industry's control: the trajectory of U.S. interest rates, the finalization of stablecoin and market structure legislation, and the willingness of traditional custody infrastructure to support tokenized fund shares at scale. The data so far indicates steady institutional adoption, not speculative froth — a distinction worth noting.
