BlackRock / BlackRock USD Institutional Digital Liquidity Fund (BUIDL)
BlackRock BUIDL named in OKX and Standard Chartered collateral framework
Summary: Standard Chartered announced a joint framework with OKX and BlackRock that would allow OKX to accept BlackRock's BUIDL tokenized short-term U.S. Treasury fund as collateral, with Standard Chartered providing custody. The draft is scoped to the BUIDL/tokenized-collateral ecosystem and avoids broad BlackRock adviser-entity claims.
Why it matters: The update may matter as market-infrastructure context for tokenized fund usage and collateral arrangements, while avoiding crypto hype or investment-merit language.
Summary
Standard Chartered announced a joint framework with OKX and BlackRock to support a tokenized real-world-asset collateral arrangement. The Standard Chartered source says OKX will accept BlackRock’s tokenized short-term U.S. Treasury fund, BUIDL, as collateral, with Standard Chartered providing custody support.
This draft is scoped to the BlackRock USD Institutional Digital Liquidity Fund / BUIDL ecosystem and the collateral-infrastructure use case described by Standard Chartered. It should not overclaim the exact BlackRock adviser entity, tokenized-market adoption, or investment merits of BUIDL or any digital-asset strategy.
Why it matters
For due-diligence readers, the item is relevant as a public market-infrastructure signal: a large bank, an exchange, and a tokenized fund product are describing a collateral framework for institutional clients. That may help readers track how tokenized Treasury products are being positioned in custody, collateral, and trading workflows.
The announcement is not a recommendation to use tokenized collateral, invest in BUIDL, trade on OKX, or assess the safety of any digital-asset arrangement.

9AT filing context
No broad BlackRock ADV or 13F context is used as support for this draft. The data-analyst handoff noted that BlackRock appears as a large multi-entity adviser platform, but also warned not to use broad BlackRock scale for a product-specific tokenized Treasury collateral story unless the exact fund, product, adviser entity, and source support are clean.
Accordingly, the public copy relies on the Standard Chartered source for the event facts and keeps the filing/data context limited to product scoping. The post should not imply that general BlackRock platform scale validates the collateral framework, fund risk profile, or tokenized-asset adoption.
What to watch
Watch for BlackRock/BUIDL product materials, Standard Chartered custody updates, OKX institutional-client materials, regulatory disclosures, and public evidence of whether the framework moves from launch announcement to sustained collateral usage.
