BNB News Today: BlackRock's BUIDL Drives $16T RWA Tokenization Wave with BNB Chain Expansion

BlackRock's tokenized U.S. Treasury fund, BUIDL, has expanded to the BNB Chain, marking a pivotal step in the integration of traditional finance with blockchain technology. The move, announced in late November 2025, aims to enhance accessibility for institutional investors by leveraging the BNB Chain's low transaction costs and high scalability. This expansion follows BUIDL's initial launch on Ethereum earlier in 2025 and builds on the fund's multi-chain strategy, which now spans eight major blockchain networks.

The BUIDL fund, managed by BlackRock, offers investors exposure to short-term U.S. Treasury securities with yields ranging between 3.7% and 5%.

By tokenizing these assets, BlackRock enables seamless, on-chain transactions while maintaining regulatory compliance under U.S. securities laws. The BNB Chain deployment, facilitated by tokenization partner Securitize and cross-chain bridge Wormhole, allows for faster settlements and reduced fees-often below $0.01 per transaction-compared to Ethereum's higher gas costs. This scalability is critical for attracting institutions in emerging markets, where cost efficiency is a key barrier to adoption.

A significant development accompanying the BNB Chain expansion is Binance's approval of BUIDL as off-exchange collateral. Institutional traders can now use BUIDL tokens to secure positions on Binance without transferring custody of their assets, enabling yield generation while maintaining liquidity. Binance's triparty banking services, including MirrorRSV and Banking Triparty, facilitate this process by acting as neutral custodians. The integration aligns with Binance's broader push into regulated digital assets and underscores the growing demand for yield-bearing, dollar-pegged assets among institutional clients.

Carlos Domingo, CEO of Securitize, emphasized the strategic importance of the expansion: "BUIDL's deployment on BNB Chain and its use as collateral on Binance further extends its reach and utility. We're continuing to bring regulated real-world assets on-chain while unlocking new forms of utility previously out of reach". The collaboration also highlights BNB Chain's role as a hub for institutional-grade blockchain solutions, with its ecosystem now supporting over $40 billion in cross-chain transfers via Wormhole.

BlackRock's USD Institutional Digital Liquidity Fund (BUIDL) has grown to $2.9 billion in assets under management as of late 2025, making it the largest tokenized real-world asset (RWA) in the market. The fund's multi-chain approach- deployed on Ethereum, Solana, Polygon, and others -reflects BlackRock's commitment to interoperability and avoiding single-chain dependency. This strategy not only democratizes access to U.S. Treasury yields but also aligns with regulatory trends emphasizing transparency in digital markets.

The move signals a broader shift in RWA tokenization, a sector projected to reach $16 trillion by 2030, according to Boston Consulting Group. By bridging traditional finance and blockchain, BUIDL enables institutional investors to deploy capital more efficiently, with yields offsetting trading fees and counterparty risks mitigated through triparty custodians. For example, a $10 million BUIDL collateral position could generate approximately $370,000 annually in yields.

BlackRock's expansion to BNB Chain also strengthens its partnership with Binance, which has integrated BUIDL into its institutional offerings. Binance's Head of VIP & Institutional, Catherine Chen, noted that the integration addresses client demand for "interest-bearing stable assets" to hedge trading positions. Meanwhile, BNB Chain's Head of Business Development, Sarah Wong, highlighted the platform's focus on scalable, secure financial applications, stating, "We're excited to welcome BUIDL to our ecosystem".

As on-chain finance evolves, BlackRock's BUIDL fund exemplifies how traditional asset managers are embracing blockchain to enhance liquidity and efficiency. With institutions increasingly adopting tokenized assets, the collaboration between BlackRock, Binance, and BNB Chain could set a precedent for future hybrid financial systems.
