In a corridor where risk is whispered like a secret, OKX has admitted BlackRock’s BUIDL, a tokenized U.S. Treasury, into its institutional collateral framework, with Standard Chartered standing as the patient sentry. The result, as some would call it, lets eligible institutional and VIP clients press BUIDL into service as trading margin.
Summary
- OKX grants eligible institutional and VIP clients the use of BlackRock’s BUIDL as trading collateral.
- Standard Chartered keeps BUIDL off-exchange while OKX tends the margins and the delicate art of liquidation.
- BUIDL will be treated as fungible with USD, USDC and other dollar assets inside OKX’s margin loom.
Clients may cradle the asset off-exchange under Standard Chartered’s custody while trading within OKX Middle East, or deposit BUIDL directly on the exchange, depending on their setup and penchant for paperwork that tastes like civilization.
The companies described the arrangement as a G-SIB-backed off-exchange tokenized collateral framework, a grand phrase for a modest bit of bartering that builds on OKX’s existing collateral mirroring program with Standard Chartered.
Rifad Mahasneh, CEO of OKX Middle East, North Africa and CIS, said the update reveals how tokenized assets can support active trading rather than drift about like idle coins in a drawer.
He noted that BUIDL will be treated as fungible with USD, USDC and other dollar-based stablecoins inside OKX’s margin system. Clients will retain ownership of the fund and its yield, which is what every investor dreams of, if the dream includes a ledger and a smile.
Standard Chartered holds client collateral
Standard Chartered will act as the off-exchange custodian, keeping client collateral separate from OKX’s own assets-the sort of separation that would make a good alibi.
OKX will manage real-time margining and liquidation through its internal risk systems. Mahasneh said the structure adheres to traditional finance standards, though details on stress-period margin calls were not provided, perhaps lost in the coffee or the auditors’ jokes.
Tokenized Treasury competition grows
BlackRock’s BUIDL fund is tokenized by Securitize. It invests in cash, U.S. Treasury bills and repurchase agreements, with yield distributed onchain, which sounds very modern until you recall the old desk calendar and the old Soviet joke about plans.
The launch adds to the growing use of tokenized real-world assets in crypto market infrastructure. Binance has also added tokenized Treasury products, including BUIDL and Franklin Templeton’s BENJI fund, to collateral frameworks, because apparently everyone loves a token with a passport.
OKX said the service is live for eligible institutional and VIP clients through OKX Middle East. The company plans to expand access based on jurisdiction and client demand, because markets, like sunsets, always want to travel a bit further.
