The tokenized U.S. Treasury bond market is once again experiencing a change in leadership. The BUIDL fund, managed by BlackRock and Securitize, has reclaimed the top spot, overtaking competitor USYC from Circle. Assets under management for BUIDL have reached approximately $2.8 billion, accounting for about 18.5% of the entire market, valued at $15.1 billion.
Dynamic Battle for the Top Spot
Tokenized Treasury bond funds offer institutional investors a unique opportunity — to hold short-term U.S. securities directly on the blockchain. This provides round-the-clock liquidity and instant transaction execution, sharply contrasting with traditional settlements that can stretch over several days.
That is precisely why such products have become a natural choice for deploying idle funds to generate yield. However, competition here is extremely intense, and leadership changes rapidly.
Circle's USYC fund, which recently overtook BUIDL, has shown impressive growth — from $600 million to nearly $3 billion in a year. By the end of August, its assets reached $2.9 billion, allowing it to temporarily surpass BUIDL with its $2.7 billion. But already this week, BUIDL has regained its position, pushing the competitor to second place.
What Lies Behind the Shifts
It is important to understand the structure of these products. BUIDL is a dollar liquidity fund from BlackRock, managed by Securitize. USYC operates on the Hashnote platform and belongs to Circle, which integrated it into its stablecoin business after acquiring Hashnote in 2025.
The fact that no fund holds leadership for long says a lot. Institutions are not simply grabbing the first product they come across — they are actively comparing terms and reallocating capital in search of optimal yield and reliability.
Such musical chairs is a sign of a healthy and mature market that is forming into a full-fledged category, where advantage is not granted by inertia. Competition drives issuers to improve terms and introduce innovations.
The key question now is whether institutional interest will remain limited to government bonds or spread to other on-chain finance instruments. For now, the market is growing mainly through Treasury securities, but the entire tokenization ecosystem of real-world assets (RWA) continues to scale.
My view: BUIDL's return to the top is not just statistics, but a signal that the BlackRock brand and trust in Securitize remain decisive factors for conservative investors. However, USYC's resilience shows that Circle, leveraging its stablecoin infrastructure, is capable of creating serious competition. The battle for leadership in RWA is just beginning, and it promises to be exciting.
