Standard Chartered now provides institutional custody of Ripple's dollar-pegged stablecoin RLUSD through its Dubai International Financial Centre branch, the bank announced Monday. The service covers RLUSD issued on the XRP Ledger and operates under supervision of the Dubai Financial Services Authority.

The more consequential half of the announcement is not live. Standard Chartered and LMAX Group, a London-based venue for currencies and crypto, plan a system the bank calls collateral mirroring: RLUSD stays in the bank's custody while LMAX receives a mirrored record of its value that counts toward a client's margin. If the exchange failed, the collateral would still sit at Standard Chartered, one of 29 banks the Financial Stability Board designates as too big to fail and subjects to tougher capital rules. The bank said the integration remains subject to final documentation, testing and regulatory approvals, and it gave no launch date — the caveat matters more than the promise.

"Institutional clients want to participate in digital asset markets without compromising on how their assets are safeguarded," said Waqar Chaudry, who heads digital assets in the bank's securities services unit. Custody, however, grants the institution legal responsibility for the assets alongside permission to supervise, freeze and control them while they are held.

What is RLUSD, and how large is it?

RLUSD is a stablecoin designed to hold a $1 peg through backing in dollars, U.S. government bonds and cash equivalents. Ripple launched it in December 2024 on Ethereum and the XRP Ledger, the public blockchain closely tied to Ripple; Standard Chartered's custody covers only the XRP Ledger version. The token has grown to roughly $2.45 billion in market capitalization. That figure equals less than 1% of a stablecoin market worth about $306 billion — meaning RLUSD remains a small instrument in the segment it is trying to serve.

The Dubai regulator approved RLUSD in June 2025, according to the announcement.

Why does custody-backed margin matter?

Collateral, or margin, is the money a trader parks with a venue as a safety deposit against potential losses. Under the conventional model, the exchange itself holds that money. Under mirroring, the tokens never travel to LMAX, which removes exchange custody risk from the trade — a structural answer to a failure mode the industry has experienced repeatedly.

The arrangement carries operational weight for the bank as well. Standard Chartered has offered crypto custody in Dubai since 2024, and in July it said it became the first global systemically important bank to let institutions mint and redeem Circle's USDC directly. The RLUSD mandate extends that franchise rather than starting a new one.

The unresolved question is timing. Until the documentation, testing and approvals finish, the custody announcement stands on its own, and clients can hold RLUSD at the bank but cannot post it as trading collateral with LMAX. Market participants will be watching for a firm go-live date from Standard Chartered and LMAX before treating mirrored RLUSD margin as available infrastructure.
