USYC: The Yield-Bearing Stablecoin Revolutionizing Tokenized Treasury Markets
In the rapidly evolving landscape of decentralized finance (DeFi) and tokenized real-world assets (RWAs), USYC has emerged as a groundbreaking financial instrument that bridges traditional treasury markets with blockchain technology. This tokenized money market fund represents a significant innovation in how investors can access yield-bearing assets while maintaining the speed and transparency of blockchain-based transactions [1].
Background and Origins
USYC is the tokenized representation of the Hashnote International Short Duration Yield Fund Ltd. (iSDYF), which was incorporated as an exempted company in the Cayman Islands on March 17, 2023. The fund was originally incubated by Cumberland Labs, a subsidiary of the prominent trading firm DRW, before being acquired by Circle, the issuer of the $48 billion USDC stablecoin, in January 2025 [2]. Each USYC token serves as a digital representation of a share of the Hashnote International Short Duration Fund Ltd, which is a Cayman Islands registered mutual fund [5].
The acquisition of Hashnote by Circle for an undisclosed amount marked a strategic consolidation in the tokenized asset space, combining Circle's stablecoin expertise with Hashnote's pioneering work in tokenized treasury products. This move positioned Circle to compete more effectively in the rapidly growing tokenized real-world asset market, which has seen explosive growth as institutional investors seek yield-bearing alternatives to traditional stablecoins.
Purpose and Core Function
Unlike traditional stablecoins such as USDC or USDT that maintain a stable $1.00 value, USYC serves a fundamentally different purpose. The token functions as a yield-bearing digital asset that appreciates in value over time, providing holders with exposure to short-term U.S. Treasury bill yields while maintaining the operational benefits of blockchain technology.
USYC's primary purpose is to democratize access to institutional-grade money market investments through tokenization. By converting traditional treasury investments into ERC-20 tokens, USYC enables 24/7 trading, near-instant settlements, and seamless integration with DeFi protocols—capabilities that traditional treasury investments cannot offer.
The fund's investment strategy focuses on short-term U.S. Treasury Bills and repo/reverse-repo activities, providing investors with returns tied to short-term Federal Reserve rates. This approach offers a relatively low-risk way to earn yield while maintaining high liquidity and capital preservation characteristics typical of money market funds [3].
Distinguishing Features
Yield Generation
The most significant differentiator of USYC from traditional stablecoins is its yield-bearing nature. While stablecoins like USDC maintain a stable value, USYC appreciates over time as it earns short-term risk-free rate returns from its underlying treasury investments. This appreciation mechanism allows holders to earn passive income simply by holding the token.
Productive Collateral
USYC has gained traction as "productive collateral" in various DeFi applications. Unlike traditional collateral that sits idle, USYC continues to generate yield even when used to back trades or loans. Major platforms including Deribit [4] and Binance have recognized USYC as eligible collateral for derivatives trading, allowing traders to maintain their yield exposure while accessing leverage.
Institutional-Grade Structure
The fund operates under a robust regulatory framework with strong controls across regulatory and credit dimensions. The underlying assets consist primarily of short-term U.S. Treasury securities, providing institutional-level security and transparency. The fund maintains proper segregation of assets and adheres to stringent compliance standards expected in traditional asset management.
Blockchain Transparency
All USYC transactions and holdings are fully trackable on the blockchain, providing unprecedented transparency compared to traditional money market funds. Investors can verify fund holdings, track their positions in real-time, and benefit from the composability that comes with tokenization.
Rapid Liquidity
The tokenized structure enables near-instant redemptions into USDC, addressing one of the traditional pain points of money market funds where redemptions can take days to settle. This liquidity feature makes USYC attractive for both retail and institutional investors who value quick access to their capital.
Market Performance and Adoption
USYC has experienced remarkable growth since its inception, reaching over 500 million dollars in assets under management [6]. This rapid scaling has made it the largest tokenized treasury and money market fund globally, surpassing even BlackRock's BUIDL fund at various points.
The token's growth has been particularly accelerated by its adoption within the DeFi ecosystem. Notably, USYC serves as the primary backing asset for the Usual protocol's USD0 stablecoin [7] , which itself reached over 500 million dollars in market capitalization. This integration demonstrates how USYC has become foundational infrastructure for next-generation DeFi protocols seeking yield-bearing collateral.
The fund's market value stems from several key factors. First, it provides institutional and retail investors with a seamless way to earn treasury yields without the operational complexity of traditional money market funds. Second, its tokenized nature enables 24/7 liquidity and trading, premium features in global markets. Third, its use as productive collateral in DeFi applications creates additional utility value beyond simple yield generation.
Historical Development and Milestones
The development of USYC represents a significant milestone in the evolution of tokenized real-world assets. Launched in 2023, it quickly established itself as a leader in the tokenized treasury space during a period when similar products from major asset managers like BlackRock and Franklin Templeton were also gaining traction [8].
Key milestones in USYC's history include:
March 2023: Incorporation of Hashnote International Short Duration Yield Fund Ltd.
2023-2024: Rapid asset growth and establishment as the leading tokenized money market fund
December 2024: Integration with the Usual protocol, driving significant additional demand
January 2025: Acquisition by Circle, providing institutional backing and expanded distribution capabilities
The timing of USYC's development coincided with a broader institutional awakening to the potential of tokenized assets. As traditional financial institutions began exploring blockchain technology for asset management, USYC provided a practical demonstration of how tokenization could enhance traditional investment products.
Market Value Drivers
USYC maintains its market value through several interconnected mechanisms. The underlying treasury investments provide fundamental value through yield generation, while the tokenized structure creates additional premium through enhanced liquidity and utility.
The token's market price typically trades at a premium to its net asset value (NAV) due to the convenience and additional features it provides. This premium reflects the value that market participants place on 24/7 liquidity, blockchain transparency, and DeFi composability—features unavailable in traditional money market funds.
Furthermore, USYC's adoption as collateral across multiple platforms creates ongoing demand pressure. As more institutions recognize USYC as acceptable collateral, its utility value increases, supporting higher market valuations. The integration with major exchanges like Binance for institutional derivatives trading further enhances this utility proposition.
Future Prospects
The prospects for USYC appear robust, particularly following its acquisition by Circle. The integration with Circle's ecosystem provides access to a broader distribution network and institutional client base, potentially accelerating adoption among traditional financial institutions exploring blockchain-based assets.
Several trends support USYC's continued growth. The increasing institutional adoption of tokenized assets, growing demand for yield-bearing alternatives to traditional stablecoins, and the expansion of DeFi protocols requiring productive collateral all create favorable market conditions.
Circle has indicated plans to expand USYC's presence across additional blockchain networks and integrate it more deeply with the broader Circle ecosystem, including potential synergies with USDC for institutional clients. The company's established relationships with traditional financial institutions position USYC to capture market share as tokenized assets move from experimental to mainstream adoption.
Conclusion
USYC represents a significant innovation in the convergence of traditional finance and blockchain technology. By successfully tokenizing money market fund exposure, it has created a new category of yield-bearing digital assets that provide institutional-grade returns with blockchain-native benefits.
The token's rapid growth to over $1.5 billion in assets under management demonstrates strong market demand for yield-bearing alternatives to traditional stablecoins. Its adoption as collateral across multiple platforms and integration with major DeFi protocols positions it as foundational infrastructure for the next generation of blockchain-based financial services.
As the tokenized asset market continues to mature, USYC's combination of regulatory compliance, institutional backing through Circle, and technical innovation positions it well to maintain its leadership in the tokenized treasury space while expanding into new use cases and markets.
