Standard Chartered launches RLUSD custody, plans LMAX collateral link
Standard Chartered launched RLUSD custody in Dubai; a planned LMAX link may let clients use tokens as collateral without moving them to the venue.

Standard Chartered has launched institutional custody for Ripple USD (RLUSD) on the XRP Ledger, while planning a separate link that could let eligible clients use the stablecoin as collateral for certain LMAX products. The bank said in its announcement on RLUSD custody and the planned integration on 12 October that custody is live through its Dubai International Financial Centre branch, regulated by the Dubai Financial Services Authority. The collateral arrangement is still a future capability.
What does the live custody service cover?
Eligible clients can hold RLUSD issued on the XRP Ledger within Standard Chartered’s digital asset custody infrastructure. The announcement does not say that the bank issues RLUSD, nor does it describe which custody controls or wallet arrangements it uses for the service. It identifies the asset’s network and the branch providing custody, but gives no client count, minimum balance or launch volume.
The distinction matters because custody and collateral use are separate parts of the plan. The custody service is available now; the parties have only said they intend to make RLUSD eligible collateral for agreed LMAX Group products and solutions across trading and collateral management. The Block’s report on the launch and planned integration likewise says the collateral link has no announced launch date.
How is collateral mirroring meant to work?
Under Standard Chartered’s collateral mirroring model, eligible RLUSD remains in the bank’s custody while its value is mirrored to LMAX Group. That would allow the trading venue to recognize the value of designated collateral without requiring clients to transfer the underlying tokens directly to LMAX. The proposed arrangement connects bank custody with LMAX’s trading and collateral-management infrastructure; it does not describe an on-chain transfer to LMAX or name a smart contract that performs the mirroring.
The stated purpose is to give institutional clients more flexibility in holding and deploying assets, reduce transfer-related operational risk and optimize counterparty exposure. Those are the parties’ expected benefits, not reported performance results. The announcement does not specify how collateral value will be calculated or refreshed, what haircuts or eligibility thresholds will apply, how margin calls will work, or what happens if a custody balance and a mirrored balance diverge. Those details would determine how the model handles price moves, delayed updates and disputes over available collateral.
What must happen before LMAX clients can use RLUSD?
The parties say the future capabilities remain subject to final documentation, successful testing, applicable laws and regulations, internal approvals and jurisdictional readiness. No implementation date or list of eligible LMAX products has been published. In practice, that leaves the live custody service distinct from any right to post RLUSD at LMAX: clients cannot infer from the announcement that every LMAX product will accept the token or that the collateral link is already operational.
Standard Chartered, Ripple and LMAX Group describe the project as a coordinated framework combining RLUSD on the XRP Ledger, the bank’s custody capabilities and LMAX’s institutional market infrastructure. The next verifiable step is implementation detail: the final terms must identify which clients and products qualify and how the mirrored value is maintained and acted on. Until then, the confirmed change is custody availability in Dubai, with collateral mirroring still planned.
