Blackrock anchors OKX’s tokenized Treasury collateral framework with Standard Chartered, enabling institutions to trade while maintaining yield and regulated custody.
Key Takeaways:
OKX framework, introduced April 28, 2026 enables tokenized U.S. Treasury assets as trading margin and collateral. Blackrock BUIDL fund delivers tokenized Treasury exposure with yield benchmarked to the U.S. Federal Funds rate. Standard Chartered custody keeps assets off-exchange while supporting real-time trading access and uninterrupted yield generation. Tokenized Treasury Collateral Expands Across OKX TradingStandard Chartered provides regulated custody, allowing assets to remain off-exchange while still supporting trading activity. This removes the need to separate idle capital from active positions and connects traditional financial exposure directly with digital trading systems.
Custody Model Keeps Yield Active While Trading ContinuesThe framework connects on-exchange and off-exchange environments into a single operational model. On OKX, BUIDL can be used as margin across trading activities, where yield continues to accumulate. Off-exchange, the same holdings remain secured within Standard Chartered’s custody while still supporting trading exposure. This dual structure maintains continuity between custody and execution, avoiding asset transfers that interrupt positioning or returns.
The result is a shift in how institutions manage capital in digital markets. Exposure to short-term U.S. Treasury instruments remains intact while being actively deployed in trading strategies. Yield persists, custody protections meet global banking standards, and trading continues in real time through OKX infrastructure. OKX detailed:
“This collaboration brings together the strengths of three global institutions: Blackrock’s market leadership in tokenized treasury funds, Standard Chartered’s regulated custody as a Tier 1 Global Systemically Important Bank, and OKX’s institutional-grade trading and margining infrastructure.”
With assets anchored to cash and government-backed instruments, the framework reflects a broader move toward embedding tokenization into financial systems.
