BlackRock BUIDL Fund Crosses $2 Billion: Institutional RWA Tokenisation Reaches Escape Velocity

BlackRock's BUIDL fund — the BlackRock USD Institutional Digital Liquidity Fund, launched on Ethereum in March 2024 — has reached $2 billion in assets under management, establishing itself as the largest tokenised real-world asset product in existence by a significant margin.

The fund holds short-duration US Treasuries and repurchase agreements, with the yield passed through to tokenised BUIDL holders on-chain. It is available exclusively to qualified institutional investors, with a minimum subscription of $5 million, and is issued and managed by BlackRock Financial Management with Securitize as the token transfer agent.

Why BUIDL Matters

BUIDL's growth is significant not for its yield (roughly equivalent to prevailing money market rates) but for what it demonstrates: that the world's largest asset manager is comfortable holding client assets in a tokenised form on a public blockchain, and that institutional investors are willing to hold US Treasuries as ERC-20 tokens.

The fund serves a practical purpose in the DeFi ecosystem. Protocols including Ondo Finance and Superstate use BUIDL as a reserve asset for their own tokenised Treasury products (OUSG and USTB respectively), creating a layered institutional infrastructure on-chain.

Ondo Finance, which launched its OUSG product backed by BUIDL, has itself grown to over $800 million in TVL — demonstrating that DeFi-native protocols can successfully bridge institutional RWA products into on-chain liquidity.

The Broader RWA Landscape

Total tokenised RWA value on public blockchains has crossed $20 billion in 2026, including tokenised Treasuries, private credit, real estate, and commodities. Beyond BlackRock, major institutions with tokenised products on public chains now include Franklin Templeton (FOBXX on Stellar and Polygon), WisdomTree, and UBS.

Ethereum remains the dominant chain for institutional RWA issuance, though a growing share of new products is launching on Ethereum-compatible Layer 2 networks (particularly Base and ZKsync Era) to reduce gas costs for institutional treasury management.

Maple Finance, Centrifuge, and Goldfinch continue to operate private credit markets on-chain — allowing institutional lenders to originate loans to real-world borrowers through DeFi infrastructure, with loan performance data posted transparently on-chain.

Implications for DeFi

The growth of institutional RWA on-chain has significant implications for DeFi protocol design. Aave and Compound have both introduced yield-bearing RWA assets as collateral options, allowing DeFi borrowers to use tokenised Treasuries as loan collateral while continuing to earn yield on the collateral itself — an efficiency improvement over traditional crypto-only collateral.

Curve's integration of USYC (Hashnote's tokenised Treasury product) into liquidity pools has created a new category of yield-bearing stablecoin liquidity — pools where one of the pair tokens accrues interest, creating structural yield for LPs that does not depend on trading volume alone.

As BUIDL and peer products grow in scale, the line between traditional fixed-income investing and DeFi participation continues to blur — a trend that is likely to accelerate as the regulatory framework for RWA tokenisation becomes clearer under MiCA in Europe and the GENIUS Act in the United States.
