OKX Integrates BlackRock's BUIDL Fund into Collateral Framework
OKX, a global digital asset exchange, has integrated BlackRock's BUIDL tokenized U.S. Treasury fund into its collateral framework. The arrangement allows eligible institutional and VIP clients to use the yield-bearing asset as trading margin without transferring it out of Standard Chartered custody.
The BUIDL fund is tokenized by Securitize and invests in cash, U.S. Treasury bills, and repurchase agreements, with yield distributed on-chain. Clients retain ownership of the underlying asset and its yield throughout, according to Rifad Mahasneh, CEO of OKX Middle East, North Africa, and Commonwealth of Independent States.
The framework is a result of OKX's existing collateral mirroring program with Standard Chartered, launched last year to support the exchange's European expansion. The new integration marks a step beyond passive holding, demonstrating how tokenized assets can be actively deployed within live trading infrastructure.
