"Tokenization could help accelerate that future by updating the plumbing of the financial system — making investments easier to issue, easier to trade, and easier to access." — Larry Fink, Chairman & CEO, BlackRock (2026 Annual Chairman's Letter)
The tokenized U.S. Treasury market has crossed $15 billion in on-chain assets under management as of May 2026, according to data from RWA.xyz and Intellectia. That figure stood at roughly $850 million two years ago and $7.3 billion at the end of 2025. The expansion — a near-18x increase from the March 2024 launch of BlackRock's BUIDL fund — has shifted the asset class from proof-of-concept to core infrastructure for stablecoin reserves, institutional derivatives collateral, and DeFi lending markets.
The competitive landscape has consolidated around five issuers controlling over 80% of assets: Circle's USYC (~$3 billion), BlackRock's BUIDL (~$2.6 billion), Ondo Finance's USDY (~$2.1 billion), Franklin Templeton's BENJI (~$2.1 billion), and Centrifuge's JTRSY (~$1.2 billion). The differentiator is no longer yield or fund structure — short-term T-bill returns cluster between 4.5% and 5.0% APY across all products — but distribution. The issuer with the deepest integration into trading, lending, and settlement venues captures the largest share of flows.
The tokenized Treasury market has grown through three distinct phases:
| Period | AUM | Catalyst | |--------|-----|----------| | Q1 2024 | ~$850M | BlackRock BUIDL launch on Ethereum via Securitize | | Q4 2025 | ~$7.3B | Multi-chain expansion; stablecoin reserve demand | | Q2 2026 | ~$15B | DeFi collateral integration; DTCC pilot announcement |
The broader tokenized real-world asset (RWA) market, excluding stablecoins, reached $31-34 billion in total value by May 2026, according to CoinGecko's RWA Report 2026 and crypto.news. Tokenized Treasuries account for roughly 45% of that figure, making them the single largest RWA category on-chain.
Ethereum hosts approximately 60% of tokenized Treasury value. The remainder is distributed across Solana, Stellar, Mantle, Arbitrum, Aptos, Sui, and Polygon, with issuers increasingly deploying across multiple chains simultaneously.
As of Q2 2026, the top five tokenized Treasury products by AUM, according to RWA.xyz:
| Product | Issuer | AUM | Fund Type | |---------|--------|-----|-----------| | USYC | Circle (Hashnote) | ~$2.9B | Short Duration Yield Fund | | BUIDL | BlackRock (Securitize) | ~$2.6B | USD Institutional Digital Liquidity | | USDY | Ondo Finance | ~$2.1B | Yield-bearing USD token | | BENJI | Franklin Templeton | ~$2.1B | FOBXX (1940 Act fund) | | JTRSY | Centrifuge | ~$1.2B | Anemoy Liquid Treasury |
Yield differentials across these products are negligible. USDY pays 4.65% APY; BUIDL and USYC cluster near 4.5-5.0%. The underlying assets are functionally identical: short-dated U.S. Treasury bills, overnight reverse repurchase agreements, and Treasury-collateralized money market instruments.
Franklin Templeton's BENJI holds a structural distinction: it is the only product registered as a 1940 Act fund with the SEC, making it available to U.S. retail investors with a $20 minimum through the Benji app. Every other major product requires qualified purchaser or accredited investor status, or restricts U.S. persons entirely (as in Ondo's USDY).
Circle's USYC overtook BlackRock's BUIDL as the largest tokenized Treasury fund in March 2026. The mechanism was not fund performance — both hold comparable portfolios and offer comparable yields. The mechanism was distribution.
Circle acquired Hashnote, USYC's original issuer, in early 2025. It then embedded USYC as the designated yield-bearing collateral inside Circle's payments network and partnered with Binance to accept USYC as off-exchange collateral for institutional derivatives positions. Binance institutional clients can now hold USYC in third-party custody via Ceffu, earning ~4.5% while simultaneously using the same token as margin for derivatives trades.
This dual-use function — yield generation plus collateral duty — eliminated the opportunity cost that previously forced institutions to choose between earning returns and posting margin. A trading desk that holds USYC earns the prevailing short-term yield while the token simultaneously satisfies margin requirements. At current short-dated U.S. Treasury yields in the 4% range, the capital efficiency gain is material across institutional portfolios.
BlackRock has responded with its own integration push. In May 2026, BlackRock filed with the SEC for two new tokenized funds and on-chain shares for an existing $7 billion money-market fund. The firm also tapped Chronicle for a new verification layer for BUIDL, aiming to expand the fund's interoperability across DeFi protocols and institutional venues.
The pattern is clear: in a market where yields are commoditized, the competitive moat is embedded distribution.
Tokenized Treasuries serve three primary functions on-chain:
1. Stablecoin Reserve Backing
Stablecoin issuers collectively hold over $300 billion in reserves, predominantly in U.S. Treasury bills. Tether's Q1 2026 attestation disclosed $191.8 billion in reserves backing $183 billion in token liabilities, with the majority allocated to short-dated Treasuries. Tokenized Treasury products allow issuers to hold reserves on-chain rather than in traditional custodial accounts, enabling real-time reserve verification.
JupUSD, launched by Jupiter on Solana, allocates 90% of reserves to BlackRock's BUIDL and 10% to USDC. This structure provides transparent, on-chain reserve backing while earning Treasury yields on the reserve base.
2. DeFi Collateral
Major DeFi lending protocols now accept tokenized Treasuries as collateral. According to FinanceFeeds, tokenized Treasuries are becoming DeFi's collateral layer, enabling users to borrow against stable, yield-bearing assets rather than volatile cryptocurrencies. BlackRock's BUIDL can now serve as collateral in decentralized lending markets, while USYC backs institutional derivatives positions on centralized exchanges.
3. Institutional Cash Management
Corporate treasuries from both crypto-native companies and traditional enterprises allocate capital to tokenized Treasuries as cash management instruments. The 24/7 settlement, programmable compliance, and on-chain transparency offer operational advantages over traditional money market fund structures that operate on T+1 settlement cycles.
The Depository Trust and Clearing Corporation — which processes virtually all U.S. equity and fixed-income trades — received a SEC no-action letter in December 2025 authorizing a three-year tokenization pilot. The pilot covers Russell 1000 constituents, major ETF indexes, and U.S. Treasuries.
DTCC plans to support initial, limited production trades of tokenized real-world assets through the DTC service in July 2026, according to CoinDesk, with a full commercial launch targeted for October 2026. Participating firms include major financial institutions and digital asset companies testing operational readiness, technical workflows, and cross-chain interoperability.
The DTCC pilot represents a structural shift. Previous tokenization efforts operated in parallel to traditional market infrastructure. DTCC's service tokenizes assets already held in DTC custody — the same settlement system that handles $2.5 quadrillion in annual transaction value — allowing tokenized instruments to access existing deep liquidity pools while maintaining traditional investor protections.
If the October 2026 launch proceeds on schedule, it will create a regulated on-ramp connecting the $15 billion on-chain Treasury market to the $26 trillion outstanding U.S. Treasury securities market.
Citi's Global Perspectives & Solutions report, "Tokenization 2030," published in June 2026, projects a base case of $5.5 trillion in tokenized assets by 2030. The forecast range runs from $2.7 trillion in a slower adoption scenario to $8.2 trillion in a faster-growth case.
Key projections from the Citi report:
The gap between the current $15 billion market and Citi's $5.5 trillion base case implies roughly 367x growth over four years. That trajectory requires the DTCC pilot to succeed, regulatory clarity to hold, and institutional adoption to accelerate beyond current rates — none of which are guaranteed.
Regulatory fragmentation. Tokenized Treasuries operate under varying regulatory frameworks across jurisdictions. Franklin Templeton's BENJI is SEC-registered; Ondo's USDY excludes U.S. persons; BUIDL requires qualified purchaser status. The GENIUS Act, if enacted, could impose new reserve requirements on stablecoin issuers that ripple into tokenized Treasury demand, but the bill's final form remains uncertain.
Smart contract risk. Every tokenized Treasury product depends on smart contract infrastructure for issuance, transfers, and redemption. While major products use audited contracts and regulated custodians, the attack surface is non-trivial. DeFi exploits totaled $840 million in losses in 2025-2026, and tokenized Treasuries sitting in lending protocols inherit those protocol-level risks.
Yield compression. The current appeal of tokenized Treasuries depends on elevated short-term rates. If the Federal Reserve resumes rate cuts, T-bill yields will compress, reducing the capital efficiency advantage that drives institutional adoption. At a 2% fed funds rate, the opportunity cost of posting yield-bearing collateral shrinks accordingly.
Liquidity mismatch. On-chain tokens trade 24/7, but the underlying Treasury bills settle on traditional market schedules. Redemption during periods of market stress could expose timing mismatches between on-chain and off-chain liquidity, particularly for smaller issuers without deep banking relationships.
Concentration risk. Five issuers control over 80% of the market. A regulatory action, smart contract exploit, or custodial failure at any single issuer would have outsized impact on the asset class.
The tokenized Treasury market has exited the experimental phase. At $15 billion in AUM, with SEC-registered products, DTCC infrastructure integration, and adoption by major stablecoin issuers and DeFi protocols, the asset class has crossed the threshold from proof-of-concept to functional financial infrastructure.
The remaining question is scale. Citi's $5.5 trillion forecast implies a rate of growth that requires structural changes to market infrastructure — the DTCC pilot, regulatory harmonization, and retail access — rather than incremental adoption. The July 2026 DTCC pilot will be the next material test: if tokenized Treasuries can trade through the same settlement system as traditional securities, the addressable market expands by orders of magnitude. If the pilot encounters regulatory or operational friction, the $15 billion market may represent a plateau rather than a waypoint.
The data suggests the plumbing is being built. Whether the capital flows through it at the scale the forecasts imply remains an open question.
