OKX, BlackRock, and Standard Chartered Launch Collateral Framework for Tokenized Treasuries

Global cryptocurrency exchange OKX has announced a collaboration with asset management giant BlackRock and multinational bank Standard Chartered to introduce a new utility framework for tokenized real-world assets (RWAs).

Announced on April 28, 2026, the initiative allows qualified institutional investors to deploy BlackRock’s BUIDL, a tokenized U.S. Treasury fund issued on public blockchains, as trading collateral on the OKX platform while simultaneously earning a U.S. dollar yield.

Crucially, the assets will be held in regulated custody by Standard Chartered, establishing the first-ever off-exchange tokenized collateral model backed by a Tier 1 Global Systemically Important Bank (G-SIB).

Solving the “Idle Capital” Dilemma

Historically, institutional investors have had to make a trade-off: either keep capital safely positioned in high-quality, liquid assets (like U.S. Treasuries) to earn a steady yield, or actively deploy that capital into trading markets where it serves as non-yielding margin.

This new framework utilizes tokenization to solve that inefficiency by integrating traditional finance (TradFi) custody with digital market infrastructure.

The operational breakdown of the framework includes:

• The Asset (BlackRock): Investors hold BUIDL, maintaining exposure to high-quality short-term U.S. Treasuries that accrue yield benchmarked against the U.S. Federal Funds rate.
• The Custodian (Standard Chartered): Off-exchange, the BUIDL tokens are safeguarded in regulated custody, providing institutional-grade security.
• The Utility (OKX): On-exchange, the custodied BUIDL can be seamlessly deposited and utilized as yield-bearing collateral across OKX’s trading and margining infrastructure.

Haider Rafique, Global Managing Partner at OKX, highlighted the practical impact of the collaboration on X (formerly Twitter):

“The goal is simple, to make tokenized RWAs actually usable. Not just something you hold but something you can post as collateral, trade against, and still earn yield on. That means: assets stay with a regulated custodian, capital doesn’t sit idle, and institutions can operate across TradFi + crypto more seamlessly.”

The exchange noted that this collaboration marks a transition for the digital asset industry—moving beyond simple price discovery and experimentation, and embedding tokenized RWAs directly into the core mechanics of global liquidity and collateral management.
