OKX Partners with Standard Chartered to Enable BlackRock BUIDL as Institutional Collateral

OKX has launched a new collateral framework in partnership with Standard Chartered, enabling eligible institutional and VIP clients to utilize BlackRock’s BUIDL tokenized Treasury fund as trading margin. The initiative marks the first instance of a globally systemically important bank (G-SIB) backing an off-exchange tokenized collateral system. By integrating BUIDL, OKX aims to bridge the gap between traditional finance and digital asset trading, turning passive margin into productive capital. Historically, cash posted as margin on crypto exchanges has remained idle, earning little to no yield while locked in collateral accounts. Under the new structure, BUIDL assets are held in regulated custody by Standard Chartered, keeping client collateral separate from the exchange's own assets. Within the OKX margin system, the fund is treated as fungible with USD and dollar-denominated stablecoins, allowing clients to retain full ownership of the underlying asset and its yield. This development intensifies competition among top-tier exchanges, as rivals like Binance have already integrated tokenized treasury products from BlackRock and Franklin Templeton. The framework is currently live for eligible clients through OKX Middle East, with plans for further jurisdictional expansion based on demand.
