"The use of tokenized assets as collateral expands the channels of shock transmissions within the digital asset ecosystem and to the traditional financial system." — Lisa Cook, Governor, U.S. Federal Reserve
Tokenized U.S. Treasury securities crossed $15 billion in total value in May 2026, according to RWA.xyz data, up from $380 million in Q1 2023 — a 37x increase in three years. The asset class now accounts for roughly half of the $34 billion tokenized real-world asset market (excluding stablecoins). But the headline number obscures a more consequential shift: tokenized Treasuries have stopped functioning primarily as yield instruments and started functioning as programmable collateral inside decentralized finance protocols.
Spark (formerly MakerDAO's lending arm) allocated $1 billion to tokenized Treasury products in April 2026, splitting the deployment across BlackRock's BUIDL, Superstate's USTB, and Centrifuge's JTRSY. BlackRock filed with the SEC on May 8 for two additional tokenized fund structures, expanding from a single product to a product line. The DTCC, backed by 14 Wall Street firms, is set to begin live tokenized Treasury trades in July 2026. And on May 18, Standard Chartered projected tokenized assets on public blockchains could reach $4 trillion by end-2028, with DeFi protocols as the primary throughput layer.
The Federal Reserve is watching. On May 8, Governor Lisa Cook confirmed U.S. tokenized assets had more than doubled in one year to approximately $25 billion, and placed tokenization risk — specifically collateral reuse and liquidity mismatch — inside the Fed's financial stability assessment framework for the first time.
As of mid-May 2026, RWA.xyz records $15.35 billion in tokenized U.S. Treasury value distributed across 75 products held by 60,876 unique wallets, with a blended 7-day APY of 3.53%. The broader tokenized RWA market (excluding stablecoins) stands at approximately $34 billion, with government debt comprising roughly $19 billion — over 60% of the total.
Growth has been non-linear. The market took 18 months to go from near-zero to $1 billion (late 2022 to mid-2024). It added the next $5 billion in 10 months. The most recent $9 billion arrived in under eight months. Ethereum hosts approximately 60% of tokenized RWA value, with Solana, Avalanche, and Arbitrum splitting most of the remainder.
The composition of holders has changed as materially as the size. In 2024, wallets belonged predominantly to crypto-native funds and DeFi treasuries. In 2026, the holder base includes stablecoin reserve managers, protocol liquidity layers, and — via the DTCC pilot — the beginnings of traditional broker-dealer participation.
The defining development of 2026 is not the growth in AUM but the change in how tokenized Treasuries are used. They have shifted from passive yield instruments to active collateral primitives embedded in DeFi protocol architecture.
Spark Protocol is the clearest example. Following the conclusion of Spark's "Tokenization Grand Prix" competition, a Sky (formerly MakerDAO) governance vote on April 3, 2026 deployed $1 billion across three tokenized Treasury products: $500 million to BlackRock BUIDL, $300 million to Superstate USTB, and $200 million to Centrifuge JTRSY. Spark's total TVL reached $2.4 billion, making it the single largest on-chain allocator of tokenized Treasuries. RWA revenue now accounts for over 60% of Maker/Sky's total protocol income, fundamentally changing its economic profile from one dependent on crypto collateral liquidation fees to one backed by real-world yield.
Aave has moved in the same direction through its GHO stablecoin. The protocol is working with Centrifuge to accept tokenized credit positions as collateral for GHO minting, extending the composability of tokenized assets beyond Treasuries into structured credit.
Binance accepted BlackRock's BUIDL as off-exchange collateral, allowing institutional traders to earn yield on their margin deposits rather than posting idle cash. Circle's USYC can be redeemed 1:1 into USDC, creating a direct bridge between tokenized yield and stablecoin liquidity.
The net effect: tokenized Treasuries now simultaneously generate yield, serve as collateral for borrowing, and function as liquidity backstops — roles that were previously siloed across different instruments in traditional finance.
The market is consolidating around a handful of products. According to RWA.xyz data:
| Product | Issuer | AUM (approx.) | Chain(s) | Key Feature | |---------|--------|---------------|----------|-------------| | BUIDL | BlackRock/Securitize | $2.4B | ETH, Avax, Sol, Arb, Polygon, Aptos, OP, BNB | Largest single fund; DeFi collateral integrations | | USYC | Hashnote/Circle | $1.8B (peak) | Multiple | 1:1 USDC redemption; Binance distribution | | OUSG/USDY | Ondo Finance | $1.4B+ combined | ETH, Sol, Mantle, Sui, Aptos | Retail-accessible; 4.65% APY | | FOBXX (BENJI) | Franklin Templeton | ~$700M | Stellar, Polygon, Avalanche, Arbitrum | First SEC-registered on-chain fund | | USTB | Superstate | Undisclosed | ETH | Spark allocation recipient | | JTRSY | Centrifuge | Undisclosed | ETH | Spark allocation recipient |
The competitive dynamics are instructive. Circle's USYC briefly overtook BlackRock's BUIDL as the largest tokenized Treasury fund in March 2026 — not because of superior fund performance, but because it was integrated into Binance's infrastructure. Distribution, not yield, is the primary differentiator.
On May 8, 2026, BlackRock filed two new tokenized fund applications with the SEC via Securitize:
BlackRock Daily Reinvestment Stablecoin Reserve Vehicle — Invests in cash, short-term U.S. Treasury securities, and overnight repurchase agreements backed by Treasuries. Designed specifically as a reserve backing instrument for stablecoin issuers.
Digital Share Class for BSTBL — A new digital share class for the BlackRock Select Treasury Based Liquidity Fund, a traditional money-market fund with nearly $7 billion in existing assets. BNY Mellon would maintain official ownership records on Ethereum using ERC-20 token standards. Minimum investment: $3 million.
The filings represent a shift from a single experimental product (BUIDL, launched 2024) to a multi-product tokenization strategy. The stablecoin reserve vehicle is particularly notable: it positions BlackRock as infrastructure for stablecoin issuers, not just an asset manager selling to crypto-native buyers.
In February 2026, BUIDL became tradable via UniswapX. In March, it integrated with Chronicle's on-chain asset proof verification layer. Each integration extends the token's composability within DeFi, making it usable in contexts that its prospectus never envisioned.
The Depository Trust & Clearing Corporation announced in December 2025 a partnership with Digital Asset Holdings to tokenize DTC-custodied U.S. Treasury securities on the Canton Network. Following a No-Action Letter from the SEC on December 11, 2025, the pilot is set to begin live limited trades in July 2026, with a full commercial launch scheduled for October.
The participant list reads like a directory of U.S. capital markets: Bank of America, BlackRock, BNP Paribas, Charles Schwab, Citi, Goldman Sachs, J.P. Morgan, Morgan Stanley, Nasdaq, NYSE Group, Robinhood, State Street, UBS, and Wells Fargo. Digital asset firms including Anchorage Digital, Circle, Fireblocks, Ondo Finance, Ripple Prime, and Kraken parent Payward are also participating.
This matters because DTCC processes virtually all U.S. equity and fixed-income settlement. If the pilot succeeds and expands, tokenized Treasuries could move from a parallel DeFi-native market to the canonical settlement layer for the underlying bonds themselves. The implications for collateral velocity and capital efficiency across both traditional and decentralized finance are substantial.
On May 8, 2026, Federal Reserve Governor Lisa Cook delivered a speech at Yale that placed tokenization squarely within the Fed's financial stability monitoring framework. Key points from the speech:
Scale acknowledgment: Cook confirmed U.S. tokenized assets had more than doubled in one year to approximately $25 billion, with government bond funds as the largest growth category.
Collateral contagion risk: "The use of tokenized assets as collateral expands the channels of shock transmissions within the digital asset ecosystem and to the traditional financial system," Cook stated. As tokenized assets serve simultaneously as collateral, liquidity instruments, and reserve assets, a problem in one corner of the digital asset ecosystem can propagate through multiple pathways.
Liquidity mismatch: Some tokenized assets offer on-demand redemption while their underlying assets remain less liquid. Cook flagged this mismatch as introducing run risk, particularly given 24/7 trading that removes the circuit-breaker effect of market closes.
DeFi-specific concerns: Cook noted that cyberattacks remain "relatively common in the DeFi ecosystem" and that automated smart contract execution means "humans are less able to correct for bugs or respond to outside threats."
Cook tempered these warnings: "I support and encourage financial innovation. Second, I carefully monitor the financial-stability implications that accompany all innovation." The speech signals the Fed views tokenization as a permanent feature of financial markets, not a speculative trend to be waited out.
On May 18, 2026, Geoffrey Kendrick, Standard Chartered's Global Head of Digital Assets Research, projected that tokenized assets on public blockchains could reach $4 trillion by end-2028. The projection splits roughly evenly: $2 trillion in stablecoins and $2 trillion in non-stablecoin RWAs including tokenized treasuries, equities, funds, and other financial instruments.
The report identified "composability" as the key advantage of DeFi over traditional rails — the ability for tokenized assets to simultaneously generate yield, serve as collateral, and be traded without requiring separate integrations. Standard Chartered's analysts concluded that mature DeFi protocols with strong risk metrics would capture the bulk of institutional throughput.
The projection implies roughly 120x growth from the current $34 billion RWA market (ex-stablecoins) in under three years. Even discounted significantly, the directional bet is clear: tokenized assets are expected to become a major allocation category, not a niche experiment.
The economic value distribution in tokenized Treasuries differs from both traditional fixed income and crypto-native yield products. The value chain includes:
Issuers (BlackRock, Ondo, Franklin Templeton): Charge management fees typically ranging from 15-50 basis points annually on AUM. At $15 billion in tokenized Treasury AUM and a blended 25 bps fee, the sector generates approximately $37.5 million in annual fee revenue.
Tokenization platforms (Securitize, Centrifuge): Earn transfer agent and technology fees. Securitize's role as transfer agent for BUIDL positions it as critical infrastructure.
DeFi protocols (Spark/Sky, Aave): Earn spread between the Treasury yield they receive and the rates they charge borrowers, plus governance over allocation decisions worth billions in directed capital.
Blockchain networks (Ethereum primarily): Earn transaction fees on minting, redemption, and collateral operations. At current gas prices, these fees are modest — but volume growth could change that calculus.
End holders: Receive yield minus all intermediary fees. At a 3.53% blended APY on $15 billion, holders earn roughly $530 million annually — real economic value derived from U.S. government creditworthiness, delivered through programmable infrastructure.
The critical observation: unlike much of the crypto ecosystem where value accrual is speculative, tokenized Treasury value is anchored to sovereign yield. This makes it one of the few on-chain asset classes where economic value is demonstrably not zero-sum.
$15 billion in tokenized U.S. Treasuries as of May 2026, a 37x increase from $380 million in Q1 2023, per RWA.xyz data.
Collateral use is the defining shift. Spark allocated $1 billion to tokenized Treasuries in April 2026. RWA revenue now exceeds 60% of Sky/Maker income. Binance accepts BUIDL as off-exchange collateral.
BlackRock expanded from one product to three with May 8 SEC filings, including a stablecoin reserve vehicle targeting issuers directly.
DTCC begins live tokenized Treasury trades in July 2026, with 14 major Wall Street firms and six digital asset firms participating.
The Fed is formally monitoring tokenization risk. Governor Cook's May 8 speech placed collateral reuse and liquidity mismatch inside the financial stability assessment framework.
Standard Chartered projects $4 trillion in tokenized assets by end-2028, with DeFi protocols as the primary infrastructure layer.
Distribution beats yield. Circle's USYC overtook BlackRock's BUIDL not on fund performance but on exchange integration.
Tokenized U.S. Treasuries have completed a phase transition. The first phase (2023-2024) proved the concept. The second phase (2024-2025) attracted institutional issuers. The third phase, now underway, is integration into the financial system's plumbing — as DeFi collateral, stablecoin reserves, and, via DTCC, potentially the settlement layer for the underlying bonds themselves.
The $15 billion figure understates the market's systemic significance. When BlackRock files stablecoin reserve vehicles, when DTCC onboards Goldman Sachs and Morgan Stanley to a tokenization pilot, and when the Federal Reserve dedicates a speech to tokenization's stability implications, the asset class has moved beyond crypto-native adoption into institutional infrastructure.
The economic value proposition is straightforward: sovereign yield, delivered through programmable rails, usable as collateral across both centralized and decentralized systems. Whether Standard Chartered's $4 trillion projection materializes depends on regulatory clarity, operational reliability, and the resolution of the liquidity mismatch risks that Governor Cook flagged. The direction, however, is no longer in question. The infrastructure is being built.
