OKX has added BlackRock’s BUIDL tokenized US Treasury funds to its institutional collateral framework with Standard Chartered. This move will allow eligible institutional investors and VIP customers to use BUIDL as trading margin.
Customers can hold assets outside of Standard Chartered’s exchanges while trading on OKX Middle East. Depending on your settings, you can also deposit BUIDL directly on exchanges.
The companies described the arrangement as an off-exchange tokenized collateral framework backed by G-SIB Bank. It builds on OKX’s existing collateral mirroring program with Standard Chartered.
OKX Middle East, North Africa and CIS CEO Rifad Mahasneh said the update shows how tokenized assets can support active trading rather than remaining idle.
He said BUIDL will be treated as fungible with USD, USDC, and other dollar-based stablecoins within OKX’s margin system. The customer retains ownership of the fund and its yield.
Standard Chartered holds customer collateral
Standard Chartered will act as an off-exchange custodian. The bank will hold customer collateral separately from OKX’s own assets.
OKX manages real-time margin and clearing through an internal risk system. Mahasne said the structure follows traditional financial standards, but details of margin calls during stress periods are not provided.
Competition intensifies for tokenized treasuries
BlackRock’s BUIDL fund is being tokenized by Securitize. Invest in cash, US Treasury bills, and repurchase contracts, with yields distributed on-chain.
This announcement further expands the use of tokenized real-world assets in crypto market infrastructure. Binance has also added tokenized Treasury products to its collateral framework, including BUIDL and Franklin Templeton’s BENJI fund.
OKX said the service is being offered to qualified institutional investors and VIP customers through OKX Middle East. The company plans to expand access based on jurisdiction and customer demand.
