# Securitize Expands BlackRock BUIDL Collateral Use in Crypto Prime Brokerage Tokenized Treasuries gain utility as institutional collateral in crypto trading networks - **Source:** [NewsBTC](https://brifing.si/source/1757e8d5-352f-4479-994f-79c6e6161b17) - **Published:** 2026-09-07 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/2bfd0813-0482-4ea7-a6df-12a96d4b9818 ## Collateral Expansion Announcement Securitize has enabled BlackRock's BUIDL tokenized Treasury shares to serve as off-exchange collateral across multiple crypto prime brokerages. This institutional-grade integration allows qualified traders to use BUIDL holdings for margin and lending activities beyond simple yield generation. The move represents a significant step in making tokenized assets functional within professional trading infrastructure rather than just investment products. ## BUIDL's Market Position BlackRock's BUIDL has emerged as a leading tokenized Treasury product with $375 million in assets under management as of July 2024. Unlike retail-focused tokenized assets, BUIDL restricts participation to qualified institutional investors, aligning with traditional finance compliance standards. The fund provides on-chain exposure to short-term US Treasuries while maintaining the regulatory safeguards of conventional money market funds. ## Collateral Utility Breakthrough The ability to use tokenized Treasuries as collateral addresses a critical need in crypto markets where counterparty risk remains a concern. Prime brokers can now accept BUIDL shares held in segregated accounts as margin collateral, reducing the need to maintain large stablecoin balances on exchanges. This development follows the 2022 industry collapses that exposed vulnerabilities in crypto lending practices. ## Institutional Workflow Integration Securitize's integration allows institutional traders to maintain Treasury exposure while actively using positions across multiple prime brokerage relationships. The solution combines blockchain settlement efficiency with traditional collateral management frameworks. This hybrid approach meets institutional requirements for asset safety while providing the operational benefits of tokenization. ## Market Structure Implications The collateral expansion signals maturing infrastructure for real-world asset tokenization. BUIDL's adoption by prime brokers creates a template for how regulated crypto products can interface with trading ecosystems. The development follows similar moves by Franklin Templeton and WisdomTree, though BlackRock's scale brings particular weight to the institutional adoption narrative. ## Risk Considerations While promising, tokenized collateral systems face several challenges including redemption timing (BUIDL processes redemptions weekly), legal clarity around bankruptcy scenarios, and smart contract risks. Prime brokers are implementing custom integration solutions rather than using standardized DeFi protocols. These institutional-grade adaptations differ significantly from permissionless DeFi collateral models. ## Competitive Landscape BUIDL's collateral expansion intensifies competition in the $1.2 billion tokenized Treasury market. Competitors like Ondo Finance's OUSG and Maple Finance's cash management solutions are pursuing similar institutional integrations. The race now focuses on which products can achieve the deepest liquidity and broadest acceptance across trading venues and lending platforms. ## Future of Tokenized Collateral Securitize's move demonstrates how tokenization is evolving beyond basic yield products to become functional financial infrastructure. As more prime brokers adopt BUIDL collateral, tokenized Treasuries could reshape how institutions manage cash positions in crypto markets. This development marks a quiet but significant step toward institutional crypto adoption through regulated products rather than speculative assets. ## Sources covering this story - https://www.newsbtc.com/news/securitize-expands-blackrock-buidl-collateral-use-across-prime-brokers/ — --- _Summary written by Brifing from the original reporting.
