In March 2026, the tokenization of real-world assets (RWA) reached a historic turning point. According to RWA.xyz, the total market size for tokenized US Treasuries surpassed $1.1 billion for the first time, marking a 27% increase year-to-date. In this "arms race" for on-chain risk-free yields, Circle’s USYC fund, with $2.2 billion in assets under management, overtook the BlackRock and Securitize joint BUIDL fund ($2 billion) to become the new market leader. Even more striking, BlackRock’s BUIDL saw its market share plummet from a peak of 46% to just 18%. This shift in power not only signals intensifying competition in the RWA sector but also reveals a deeper strategic contest between crypto-native demand and traditional financial giants.
Structural Shift: How Is the Power Center of Tokenized Treasuries Changing?
The transfer of market dominance didn’t happen overnight. Looking back to May 2024, BlackRock’s BUIDL leveraged its traditional finance giant status to capture nearly half the tokenized Treasury market (46%). However, after Circle strategically acquired Hashnote and launched the USYC product, it managed to surpass BUIDL in less than a year.
The current market landscape shows a clear "two peaks plus long tail" structure: Circle USYC ($2.2 billion) and BlackRock BUIDL ($2 billion) form the first tier, together accounting for nearly 40% of the market. Yet, the true shift is seen in incremental growth—USYC’s recent expansion has been concentrated on BNB Chain, with on-chain supply surging to $1.84 billion, while BUIDL’s growth has been more subdued. This indicates that market leadership is moving away from pure "brand effect" toward "use-case driven" adoption.
Growth Mechanism: Why Has Circle USYC Pulled Ahead?
Circle USYC’s rise is no accident; its core driver is precise integration into real-world scenarios. Unlike BlackRock BUIDL, which is primarily passively held as a yield-generating asset, USYC has been deeply embedded into exchange derivatives trading infrastructure.
Since July 2024, USYC has served as eligible OTC collateral on BNB Chain for institutional derivatives trading. This model allows institutions to use yield-bearing Treasuries as trading collateral, significantly boosting capital efficiency. By contrast, while BUIDL also has collateral potential, its early adoption relied more on Securitize’s channel network and lacked the explosive growth from direct integration with leading exchanges. This mechanism proves that, in institutional applications, the combination of asset yield and capital efficiency is far more attractive than yield alone.
Structural Cost: The Competitive Dimensions Behind BlackRock’s Sharp Decline
BlackRock’s market share drop from 46% to 18% is more than just a loss of share—it exposes a shift in the competitive dynamics of the RWA sector. BUIDL initially benefited from being the "first tokenized giant product," but as the market matured, the focus shifted from "who issues" to "who uses."
USYC’s ascent comes with a hidden cost: heavy reliance on a single use case. Its $1.84 billion growth is tightly tied to the Binance ecosystem, which brings scale in the short term but also introduces concentration risk. In contrast, BUIDL’s share may be falling, but its deployment network is broader (including Ethereum, Aptos, and others), backed by BlackRock’s vast traditional distribution channels. This difference between "casting a wide net" and "deep cultivation" determines each side’s gains and losses at this stage—USYC wins on speed, BUIDL holds onto breadth.
For the Crypto Industry: RWA Is Redefining On-Chain Collateral
This power shift’s impact on the crypto industry goes far beyond market share numbers. It marks RWA’s evolution from "alternative investment" to "core financial infrastructure."
Historically, crypto collateral was mainly volatile assets like BTC and ETH or zero-yield stablecoins like USDT and USDC. The competition between USYC and BUIDL proves that yield-bearing RWA can serve as collateral for derivatives trading. This opens new capital efficiency opportunities—institutions no longer have to choose between "earning yield" and "participating in trading." As traditional financial institutions like Northern Trust enter the market, RWA’s status as on-chain "cash equivalents" is being solidified. In the future, any DeFi or CeFi scenario requiring capital deposits could become a battleground for RWA.
Future Evolution: Ecosystem Differentiation and Standards Competition
Looking ahead, the tokenized Treasury market will shift from a single-product ranking race to a contest over ecosystem and standards.
Circle’s path clearly points to "embedded finance": integrating USYC into trading, lending, and other specific scenarios to make it an indispensable "Lego block" in the crypto economy. BlackRock, meanwhile, may leverage its cross-market influence to position BUIDL as a "gateway asset" connecting traditional capital with multi-chain ecosystems. Additionally, protocol-layer players like Ondo Finance are trying to redefine liquidity allocation rules through aggregator models. The competition will hinge on who can establish RWA as the de facto standard for specific tracks (such as collateral, payments, or savings).
Potential Risks: Three Hidden Concerns Amid the Boom
Despite upbeat market sentiment, risk assessment must come first.
First, regulatory uncertainty. Tokenized Treasuries are essentially on-chain securities, and their regulatory status remains ambiguous in most jurisdictions. If the SEC or other regulators tighten definitions of "security tokens," current distribution channels could be disrupted.
Second, macro yield dependence. The appeal of current RWA Treasury products is highly reliant on elevated US federal funds rates. If rates enter a downward cycle, their advantage over stablecoins or native DeFi yields may shrink, triggering capital outflows.
Third, infrastructure trust fragility. Both Circle and BlackRock rely on a "hybrid architecture" of off-chain asset custody and on-chain token mapping. Oracle attacks, custodian negligence, or opaque reserves could all lead to de-pegging risks.
Conclusion
The tokenized Treasury market’s breakthrough to $1.1 billion and Circle USYC’s overtaking of BlackRock BUIDL mark a pivotal shift from "narrative-driven" to "application-driven" in the RWA sector. USYC’s rise demonstrates that deep integration with specific trading scenarios is more explosive than relying solely on brand endorsement; BlackRock’s diluted share reveals the market is moving from issuer sovereignty to user sovereignty. Going forward, the market’s evolution will depend on regulatory sandbox boundaries, macro rate trends, and RWA’s penetration as collateral across broader crypto protocols. For the industry, the real race is just beginning—not about who issues the largest fund, but who defines the ultimate shape of on-chain liquidity.
FAQ
What are tokenized RWA Treasuries?
Tokenized RWA (real-world asset) Treasuries refer to converting traditional financial assets like US Treasuries into digital tokens that can be traded and held on the blockchain. Investors receive Treasury interest income and can use these tokens for trading or as collateral within the crypto ecosystem.What’s the difference between Circle USYC and BlackRock BUIDL?
Both are backed by similar underlying assets—short-term US Treasuries and other cash equivalents. The main difference lies in their ecosystem strategies: USYC is deeply integrated with BNB Chain’s derivatives trading, emphasizing capital efficiency and collateral utility; BUIDL relies on Securitize, with broader multi-chain and traditional distribution channels.Why has BlackRock BUIDL’s market share dropped so quickly?
The main reasons are intensifying competition and lagging use cases. As rivals like USYC rapidly grow by integrating into exchange collateral scenarios, BUIDL’s early "first-mover advantage" has been diluted. The market is shifting from "brand-driven" to "utility-driven," and BlackRock’s brand alone is no longer enough to maintain absolute dominance.How do tokenized Treasuries affect ordinary investors?
They offer a low-risk source of on-chain yield and can be used as collateral for other transactions without selling the asset, enhancing capital utilization. For everyday users, these "yield-bearing stablecoin" products may soon be easily accessible via wallets or DeFi apps.What are the main risks of investing in tokenized Treasuries?
Key risks include: regulatory risk (changes in product classification), market risk (Fed rate cuts reducing yields), technical risk (smart contract bugs or cross-chain bridge attacks), and credit risk (operational security of the underlying asset custodian).
