OKX has unveiled a groundbreaking joint framework in collaboration with BlackRock and Standard Chartered, aimed at integrating BlackRock’s BUIDL tokenized short-term treasury fund into its collateral workflows. This initiative marks a significant development as it is the first instance where a globally systemically important bank (G-SIB) has taken on a custodian role in such a setup.
The new framework allows OKX clients to hold collateral in a regulated, off-exchange custody while simultaneously trading on the integrated platform. This development is particularly beneficial for VIP and institutional clients, who can now post BUIDL as collateral, held in off-exchange regulated custody at Standard Chartered, while trading on OKX Middle East. This innovation eliminates the cumbersome process of transferring assets between different trading venues.
Moreover, BUIDL can be both deposited and traded on-exchange, and can serve as yield-bearing collateral for margin trading. The integration of BlackRock’s BUIDL—which is tokenized by Securitize, currently proposing a business combination with Cantor Equity Partners II, Inc.—with Standard Chartered’s regulated custody, and OKX’s institutional execution and margining infrastructure creates a uniquely coordinated ecosystem for collateral custody and trading. This coalition represents a significant leap toward incorporating tokenization into the broader global market infrastructure.
Key features of this framework include:
- Capital Efficiency: The ability to utilize BUIDL as collateral turns otherwise idle margin into a yield-generating asset, enhancing the efficiency of capital deployment.
- Universal Collateral: OKX is broadening the utility of Real-World Assets (RWAs) by designating BUIDL as collateral across its platform.
- Enhanced Protection: Clients benefit from trading collateral that is safeguarded by Standard Chartered, ensuring it is segregated from OKX’s assets. This arrangement allows clients to trade on OKX without needing to transfer custody, offering an added layer of protection against exchange defaults.
This collaboration highlights a new utility framework within the cryptocurrency ecosystem, merging the security of traditional finance with the agility of digital markets, and embedding tokenization firmly in global market infrastructure.
“BUIDL was designed to bring the benefits of tokenization to short-term treasury exposure, allowing qualified investors to earn US dollar yields on blockchain rails,” stated Samara Cohen, Global Head of Market Development at BlackRock. “The partnership with OKX and Standard Chartered provides qualified investors with new avenues for deploying collateral.”
Haider Rafique, Global Managing Partner at OKX, emphasized the potential of tokenizing real-world assets at scale. He noted that enabling institutions to use BUIDL as on-chain collateral on OKX’s global platform enhances capital efficiency and exemplifies how traditional financial instruments can seamlessly operate in digital markets. “Tokenization is about making existing markets faster, more transparent, and more accessible,” he remarked.
Margaret Harwood-Jones, Global Head of Financing and Securities Services at Standard Chartered, reinforced the bank’s commitment to providing innovative solutions as the financial ecosystem evolves. “Our role as custodian in this project signifies our dedication to delivering trusted solutions. By ensuring secure custody of BUIDL for this collateral use case, we facilitate client access to digital asset opportunities under high standards of protection and compliance,” she explained.
The launch of this integrated framework follows extensive testing and institutional integration. BlackRock’s BUIDL, issued on a public blockchain, invests in cash, US Treasury bills, and repurchase agreements, with yields distributed on-chain. Its incorporation into OKX’s collateral framework demonstrates that tokenized RWAs can effectively function within existing institutional workflows for trading, margining, and liquidity management.
