Standard Chartered to hold RLUSD for clients, with a plan to count it as LMAX collateral

Institutional clients of Standard Chartered can now have Ripple's dollar-pegged stablecoin, RLUSD, held on their behalf at the bank's Dubai International Financial Centre branch. Beyond that, the bank intends to let those clients post RLUSD as trading collateral at LMAX Group, with the tokens staying put at the bank the whole time. That second piece has yet to go live. Taken together, the two show traditional finance attempting to solve one of crypto's oldest headaches: what becomes of your money if the venue holding it goes under.

Three concepts explain why this matters: stablecoins, custody and collateral.

What happened

On Monday the bank said it now provides institutional custody for RLUSD issued on the XRP Ledger. Delivery of the service comes through its DIFC branch, which the Dubai Financial Services Authority regulates. In a separate move, Standard Chartered has signed up to a planned integration with LMAX Group — a London-based marketplace for crypto and currencies — under which RLUSD would qualify as collateral on agreed LMAX products.

What is RLUSD?

Stablecoins are crypto tokens built to keep a steady value — here, $1. RLUSD's backing consists of US dollars, US government bonds and cash equivalents. Ripple brought it out in December 2024 on Ethereum and on the XRP Ledger, a public blockchain with close ties to Ripple. Only the XRP Ledger version falls within the bank's new service.

RLUSD's market value has climbed to about $2.45 billion. Impressive as that sounds, it amounts to under 1% of a stablecoin market valued at roughly $306 billion. In a field where far larger tokens call the shots, it is a minor participant.

What custody actually means

Custody is finance's unglamorous plumbing. The custodian is a regulated institution that safeguards your assets and bears legal responsibility for them. In crypto, that normally means the custodian is the one controlling the private keys required to move the tokens.

A trade-off exists. Placing assets with a custodian brings added protection, yet it also puts the custodian between you and your money. Operating under regulation, that custodian may be obliged to monitor, freeze or restrict the assets it looks after. Institutions generally see such oversight as a feature rather than a flaw, since their own rules frequently demand that a regulated party hold their assets.

Collateral and the exchange problem

Leverage requires traders to post collateral, which is also known as margin. Think of it as a safety deposit that the trading venue keeps as cover against potential losses.

Under crypto's traditional arrangement, the exchange itself holds that collateral. Should the exchange fail, traders can end up as unsecured creditors queueing to get their money back. FTX's 2022 collapse drove that risk home to the market in painful fashion.

How collateral mirroring works

Standard Chartered's proposed answer goes by the name collateral mirroring. In the planned arrangement, RLUSD remains at the bank while LMAX gets a mirrored record of what it is worth, and that value is counted toward the client's trading positions. The tokens themselves are never transferred to the exchange.

Practically, that separates the place where you trade from the place where your assets are kept. Were the exchange to run into trouble, the trader's collateral would remain at Standard Chartered — one of the 29 banks the Financial Stability Board counts as globally systemically important, and which faces stricter capital rules as a result.

Waqar Chaudry, who heads digital assets in securities services at the bank, said institutions are after access to digital asset markets without any erosion in how their assets are protected. That sums up the pitch: do your trading on the venue, leave the money at the bank.

What this does and does not mean

Precision is warranted about what has actually changed. For eligible clients, RLUSD custody is up and running. The LMAX collateral arrangement, by contrast, is still at the planning stage. According to the bank, it hinges on final documentation, testing and regulatory approvals, and no date was given for when clients might begin posting RLUSD as margin.

Nor does any of this amount to Standard Chartered purchasing RLUSD or XRP. Custody is a service the bank provides, not an investment it makes. It should not be mistaken for a direct source of demand for XRP, the separate token tied to the XRP Ledger.

The step does follow a pattern. Crypto custody has been available from Standard Chartered in Dubai since 2024, and in July the bank said it had become the first global systemically important bank allowing institutions to mint and redeem Circle's USDC directly. Dubai's regulator approved RLUSD in June 2025.

What to watch next

The milestone that matters most is the LMAX integration going live. Look for confirmation that testing and regulatory approvals have been wrapped up, and for word on which LMAX products will take RLUSD as collateral.

Keep an eye, too, on whether RLUSD's market value continues to grow against the broader stablecoin market. Custody of a bank-grade standard might make it more appealing to institutions, but genuine proof of demand would be a climb from below 1% to a meaningful share.

Several things could alter the picture: delays or conditions attached to the LMAX approval, or rival large banks rolling out comparable mirroring arrangements for larger stablecoins, either of which could make RLUSD's edge short-lived.

For traders the lesson is simple. The location of your collateral counts for as much as the venue where you trade. Collateral mirroring is one effort to pull the two apart, and it deserves to be understood before it turns into standard practice.
