- OKX has added BlackRock’s BUIDL fund to its collateral framework with Standard Chartered for eligible institutional and VIP clients.
- The setup allows clients to use a yield-bearing tokenized Treasury asset as trading margin while keeping it off-exchange in regulated bank custody.
OKX is pushing further into tokenized collateral, this time by plugging BlackRock’s BUIDL fund into its existing framework with Standard Chartered.
The arrangement, announced on Tuesday, allows eligible institutional and VIP clients to use BUIDL as trading margin while the asset remains held off-exchange with the bank. Clients trading through OKX Middle East can either post BUIDL as collateral under Standard Chartered custody or deposit it directly onto the exchange.
The companies describe it as the first off-exchange tokenized collateral framework backed by a globally systemically important bank, which is a fairly pointed way of saying they want this to look closer to traditional market infrastructure than to ordinary crypto exchange plumbing.
Yield-bearing collateral moves closer to daily trading use
That is really the bigger point here. Tokenized real-world assets have spent much of the last two years being discussed as an emerging theme. What OKX is trying to show now is that they can be used inside actual trading systems, not merely held as passive onchain wrappers around conventional assets.
That matters because BUIDL is not just a tokenized dollar placeholder. It is a yield-bearing Treasury product, tokenized by Securitize, backed by cash, U.S. Treasury bills and repurchase agreements, with yield distributed onchain.
Using that as collateral while keeping it in segregated bank custody is a more serious step toward making tokenized cash-like assets useful in actual risk management.
OKX is sharpening its institutional pitch
The framework builds on OKX’s earlier collateral mirroring program with Standard Chartered, launched last year during its European push. What is new, Mahasneh argued, is the ability to show tokenized assets being used actively within the trading stack.
Standard Chartered acts as the off-exchange custodian, holding client collateral separately from OKX’s own assets, while OKX handles real-time margining and liquidation through its internal risk systems.
The competitive angle is obvious too. Other exchanges, including Binance, have also been moving tokenized Treasury products such as BUIDL and Franklin Templeton’s BENJI into off-exchange collateral structures. OKX is now trying to distinguish itself by combining a major asset manager, regulated bank custody and live exchange integration in one framework.
