BlackRock’s Tokenized Fund Has a Bank Problem

BlackRock's BUIDL fund has reached approximately $2.3 billion in assets since its 2024 launch, yet its integration into broader financial markets remains constrained by regulatory and banking hurdles. While crypto exchanges like Crypto.com, Deribit, Binance, and OKX have adopted BUIDL as collateral, traditional banking institutions remain hesitant due to capital charge requirements and legal uncertainties. A 20% risk weight for money-market funds in banking books continues to deter widespread bank adoption, despite recent CFTC rule changes that expanded eligible collateral for certain swap dealers. Standard Chartered has emerged as a key partner, providing custody for BUIDL collateral and acting as a trustee for BlackRock's new Hong Kong-based digital liquidity fund. ISDA is currently working on standardizing collateral documentation to address legal ambiguities regarding tokenized asset control and settlement timing. Although a 2023 JPMorgan pilot demonstrated the feasibility of using tokenized shares for OTC derivatives, the transition from crypto-native use cases to mainstream institutional finance requires further regulatory alignment. Ultimately, the market is waiting for parallel adoption of collateral rules by prudential regulators and clearer guidance on the legal status of private tokenized funds.
