Circle Dethrones BlackRock: How USYC Just Became the World’s Largest Tokenized Treasury — on Ethereum

Circle USYC Overtakes BlackRock BUIDL Tokenized Treasury Ethereum

The battle for dominance in the real-world asset (RWA) sector has just reached a historic tipping point. In a market where traditional finance giants have long dictated the pace, a crypto-native company has just claimed the crown. Circle, the issuer behind the USDC stablecoin, has officially overtaken BlackRock to become the largest provider of tokenized U.S. Treasury exposure.

According to the latest data from RWA.xyz, Circle’s USYC token has surged to approximately $2.2 billion in circulating supply, pushing it past BlackRock’s flagship USD Institutional Digital Liquidity Fund (BUIDL). This milestone not only highlights the shifting power dynamics in digital finance but also cements Ethereum’s position as the undisputed settlement layer for the tokenized economy.

The Numbers Behind the Takeover

BlackRock’s BUIDL fund, issued in partnership with Securitize, enjoyed an early-mover advantage, peaking at a commanding 46% market share in May 2025. However, as the overall tokenized Treasury market ballooned to a record $11 billion — growing 27% since the start of 2026 alone — the competitive landscape shifted dramatically. This surge is part of a broader institutional push, with Nasdaq and NYSE racing to put the entire stock market on Ethereum as the tokenized asset class continues its explosive growth.

Circle’s ascent was catalyzed by its strategic acquisition of Hashnote, the original issuer of USYC, in early 2025. But the real driver of this explosive growth has been the token’s utility as institutional collateral. Unlike traditional money market funds that simply sit in a brokerage account, USYC is designed to be put to work.

Why Institutions Are Choosing USYC Over BUIDL

The core advantage of tokenized Treasuries lies in capital efficiency. Investors can earn a steady, risk-free yield from the underlying government bonds while simultaneously using the tokens as collateral for trading strategies. This is a massive upgrade over holding idle cash or zero-yield stablecoins.

USYC’s recent expansion is heavily linked to its integration into institutional trading infrastructure. Binance, for example, introduced USYC as off-exchange collateral for institutional derivatives trading in July 2025. Under this structure, institutions can hold USYC with partner banks or institutional custodians like Ceffu, earning yield while trading on leverage. The regulatory groundwork for this shift was laid when the SEC advisory panel backed tokenized securities, identifying Ethereum as the biggest winner.

“Tokenized treasuries and repo as collateral is a major emerging use case and we are proud of how quickly this has grown.”

Ethereum: The Ultimate Settlement Layer

While USYC has seen significant growth across multiple chains, including BNB Chain, Ethereum remains the foundational bedrock for the broader $27 billion RWA market. The liquidity, security, and composability of the Ethereum mainnet make it the default choice for issuing high-value financial instruments.

The acceleration of the tokenized Treasury market during the January 2026 crypto downturn reveals a maturing ecosystem. Instead of converting crypto assets back to fiat and withdrawing them to traditional bank accounts during periods of volatility, institutional capital is now staying on-chain. Investors are simply rotating into yield-bearing assets like USYC, waiting for the right moment to redeploy into riskier digital assets.

What This Means for the RWA Narrative

Circle dethroning BlackRock is a watershed moment. It proves that crypto-native infrastructure companies, armed with deep integrations into the digital asset ecosystem, can outcompete traditional Wall Street titans on their own turf. The stablecoin landscape is shifting too — as Solana recently overtook Ethereum in stablecoin volume, the pressure on Ethereum to maintain its dominance as the premier settlement layer for institutional assets has never been greater.

As the tokenized Treasury market races past the $11 billion mark, the line between traditional finance and decentralized finance continues to blur. And at the center of this convergence, providing the secure ledger that makes it all possible, is Ethereum.
