On May 13, 2026, the total value locked in tokenized US Treasuries soared to a record high of $153.5 billion. According to data from rwa.xyz, this figure represents a more than 280% increase from the roughly $3.9 billion at the start of 2025. What was once dismissed by mainstream finance as a "technical experiment" in on-chain fixed income has now reached a scale that can no longer be ignored.
The significance goes beyond the absolute numbers. The overall market cap for real-world assets (RWA) surpassed $30.9 billion in May 2026, marking a 44% increase year-to-date and more than 200% growth year-over-year (source: ainvest). Tokenized Treasuries account for about half of this total, with the remainder comprised of private credit, commodity-backed tokenized assets, and tokenized equities. Notably, the active loan volume for tokenized private credit grew to approximately $18.9 billion in Q1 2026, up 180% year-over-year. All signs point to the same reality: institutional capital allocation to on-chain yield-generating assets is experiencing structural acceleration, not merely cyclical momentum.
The macro backdrop for this acceleration is equally important. Early in 2026, the prevailing market narrative was that the Federal Reserve would begin a rate-cutting cycle in the first half of the year. However, by April, the US Consumer Price Index rose 3.8% year-over-year (official US Bureau of Labor Statistics data), significantly raising the likelihood of sustained high interest rates and reducing the odds of imminent cuts. Boston Fed President Susan Collins stated in early May that inflation remains above the 2% target and that rates will stay elevated for an extended period. In this context, on-chain Treasury products offering stable nominal yields have become the natural defensive allocation for institutional capital within the crypto ecosystem.
USYC Surpasses BUIDL: The "Cross-Section" of Capital Flows
In this $153.5 billion market, asset concentration far exceeds most external observers’ expectations. The top 10 products collectively hold over $13.9 billion, and the top five account for roughly 68% of the total. A clear issuer hierarchy is emerging, with the most critical narrative unfolding between the two leading products.
Circle’s USYC currently leads with around $2.9 billion in assets, overtaking BlackRock’s BUIDL in mid-March 2026. BUIDL follows with approximately $2.58 billion, with products from Fidelity, Franklin Templeton, and Ondo rounding out the top five. USYC operates across the BNB Chain, Ethereum, and Solana networks, while BUIDL is deployed on eight blockchain networks.
In terms of issuance scale, the gap between the two is modest—less than $400 million, which is only about 0.25% of the $153.5 billion market. Yet, this small difference reflects two fundamentally distinct growth models.
USYC’s growth engine is highly concentrated in the BNB Chain ecosystem. According to Arkham Intelligence, about 94% of USYC’s supply is deployed on BNB Chain. This concentration stems from a key partnership initiated after Circle acquired Hashnote, the issuer of USYC—USYC was introduced to the BNB Chain ecosystem as off-chain collateral for institutional derivatives trading. In other words, USYC’s growth is driven not by retail subscriptions, but by institutional demand for high-quality collateral in derivatives transactions.
BUIDL’s growth trajectory shows a different structural pattern. BUIDL serves as the core reserve asset for on-chain stablecoins like Ethena’s USDtb and Jupiter’s JupUSD, providing over 90% of their reserve backing. Unlike USYC’s "collateral-driven" approach, BUIDL functions more as foundational infrastructure for stablecoins—it’s not used as trading collateral, but as the value layer supporting other on-chain dollar products.
At the micro level of capital flows, this overtaking signals a key shift in on-chain financial markets: the growth of tokenized Treasuries is no longer solely driven by traditional fund issuances, but is increasingly pulled from the demand side by crypto-native use cases—derivatives trading, stablecoin minting, and collateral management. USYC captures the former, while BUIDL is deeply embedded in the latter.
Whether USYC’s lead will persist depends on three variables: first, the trend in derivatives trading activity within the BNB Chain ecosystem; second, whether regulatory changes will accelerate BUIDL’s demand as stablecoin reserves; third, whether USYC’s compliance restriction—being available only to non-US investors—will dampen its liquidity growth potential. The lead is temporary, the path is variable, but the divergence between these two growth paradigms is structural.
Yield "Crossroads": When DeFi Yields Fall Below Treasuries
If the above is a structural analysis of capital flow distribution, zooming out to the broader crypto yield market reveals an even more striking comparison.
According to Tiger Research’s April 2026 report, Aave V3’s USDC deposit rate was around 2.7%, already below the US federal funds rate (3.5%–3.75%) and the 10-year Treasury yield (about 4.3%). During the same period, the average annualized yield in the tokenized Treasury market was about 3.4% (source: ainvest), with returns coming from US government interest payments rather than token inflation subsidies from crypto protocols.
This isn’t just a routine reshuffling of yield rankings. Since 2022, the spread between DeFi yields and traditional Treasury yields has steadily narrowed to nearly zero, and at times has inverted. DeFi yields, heavily reliant on inflationary token incentives, are losing appeal to institutional capital and rational investors in a high-rate environment.
Industry tracking data shows that since 2026, DeFi protocols have lost hundreds of millions of dollars to security breaches. In contrast, tokenized Treasuries are managed by licensed custodians, with compliant issuance and on-chain verification frameworks that significantly reduce the attack surface for smart contract exploits. When yield advantages disappear but risk premiums remain, institutional investors have little hesitation in choosing between the two.
The essence of this competition isn’t "RWA eliminating DeFi," but rather that a high-rate environment acts as a filter, helping the market distinguish which yields are from genuine asset cash flows and which are from self-reinforcing token subsidies. The former exerts structural pressure on the latter in a high-rate era—this is the core mechanism of the so-called "crowding-out effect."
However, it’s important to clarify that "crowding out" does not mean "replacement." DeFi still hosts scenarios that tokenized Treasuries cannot cover, such as complex structured yield strategies, on-chain derivatives portfolios, and community-driven products relying on protocol governance value. What tokenized Treasuries are crowding out are inefficient DeFi strategies with unclear yield sources, sustained only by inflationary subsidies—not the inherent value of the decentralized finance ecosystem.
Industry "Multi-Directional Race": From Platform Launches to Regulatory Battles
Around May 13, 2026, several parallel industry developments together painted a busy picture for the tokenized fixed income market.
JPMorgan applied to launch an Ethereum-based tokenized government money market fund, JLTXX, primarily investing in short-term US Treasuries and fully collateralized overnight repo agreements. The timing itself is a signal—entry by one of the world’s largest banks means supply-side competition in tokenized Treasuries is rapidly expanding from crypto-native institutions to traditional financial giants.
Meanwhile, BlackRock filed applications with the SEC on May 8 for two new tokenized funds targeting the yieldless stablecoin market. The firm also publicly opposed the US Office of the Comptroller of the Currency’s proposed rule to cap tokenized reserve assets at 20%, arguing the cap should be based on asset quality, not ledger format. The outcome of this regulatory friction will directly impact BUIDL and similar products’ expansion within the banking system.
At the ecosystem level, Animoca Brands and Nuva Labs jointly launched the NUVA Ethereum marketplace platform on the same day, aiming to bring traditional credit assets on-chain for integration into DeFi. While not a direct addition to tokenized Treasuries, it signals that the on-chain fixed income market is expanding from "pure Treasuries" to "multi-asset classes"—after Treasuries, mortgages, private credit, and commodity tokenization are coming on-chain in sequence.
Regulatory currents are also moving beneath the surface. In January, three SEC divisions issued a joint statement on tokenized securities; in March, Nasdaq received approval for a rule change allowing securities trading in tokenized form; and the GENIUS Act’s progress is providing a new regulatory framework for stablecoin and tokenized asset reserves. These multi-threaded regulatory advances point to a common direction: tokenized fixed income is moving from a "regulatory gray area" to "compliant infrastructure."
The current phase of industry competition is no longer about a single product or track, but a three-dimensional parallel structure—product dimension (USYC vs. BUIDL scale race), channel dimension (exchange integration, stablecoin embedding, platform distribution), rule dimension (OCC cap disputes, SEC classification framework, legislative timelines). Breakthroughs or setbacks in any dimension could reshape market share distribution.
Are Institutions Actually "Using" It?
Every industry narrative needs to be validated by facts. The central question is: Are institutional investors truly using blockchain to reshape the fixed income market, or is it merely a new issuance channel?
It’s crucial to distinguish two different levels of "usage." The first level is purchasing behavior—institutions allocating on-chain Treasury products as yield-generating cash management tools. In this sense, institutions are indeed "using" these products, as evidenced by the steadily rising number of active on-chain holding addresses. However, most holders remain crypto-native protocols and funds; direct participation from traditional pension funds, university endowments, and insurance capital is still limited.
The second level is infrastructure transformation—whether financial institutions are using blockchain to replace traditional clearing, settlement, and custody processes. This is the true meaning of "reshaping." At this level, there is tangible progress. The US securities depository and settlement company received a no-action letter from the SEC in 2025, planning to launch production-grade tokenization services for US Treasuries, having processed trillions of dollars in transactions annually. Settlement times for tokenized Treasuries have compressed from T+1 or T+2 to near-instant, which delivers direct economic value for derivatives trading and stablecoin minting scenarios that rely on rapid collateral movement.
The prudent conclusion is: Institutions are genuinely using blockchain to reshape the issuance and collateral management layers of the fixed income market, but there is still a significant gap before "full migration of fixed income infrastructure on-chain." Current applications are closer to "on-chain packaging of traditional products" rather than a "chain-native fixed income ecosystem."
Conclusion
$153.5 billion isn’t the end point—it’s a benchmark. It means tokenized Treasuries have evolved from a narrative needing "proof of feasibility" into an asset class that can be measured for growth. The capital flow details behind Circle USYC overtaking BlackRock BUIDL are just a cross-section of the micro-level competition in this market; the "crowding-out effect" of high inflation on DeFi yields is the macro transmission mechanism.
But all these insights rest on a common assumption: the yield from tokenized Treasuries comes from the US government’s credit and interest payments, not from token subsidies by crypto protocols. This assumption defines the fundamental difference between the RWA narrative and all previous crypto narratives—when real-world asset cash flows are brought on-chain, the standard for measuring asset value finally returns to the cash flow itself.
