What was announced

The joint release, dated Singapore, 12 October 2026, and published by LMAX Group, has two parts.

The first part is live. Standard Chartered "now supports institutional custody" of RLUSD issued on the XRP Ledger (XRPL). Eligible clients get access to the bank's existing digital asset custody infrastructure, and the service runs through Standard Chartered Bank's DIFC Branch, which is regulated by the Dubai Financial Services Authority (DFSA). The release does not say which client types qualify, what the fees are, or whether RLUSD on Ethereum is covered; it names only the XRPL version.

The second part is a plan. LMAX Group, Ripple and Standard Chartered say they intend to make RLUSD "eligible collateral" for agreed LMAX products across trading and collateral management, and that LMAX has agreed to adopt Standard Chartered's collateral mirroring model. The release states plainly that these future capabilities "remain subject to final documentation, successful testing, applicable laws and regulations, internal approvals and jurisdictional readiness." No launch date was given.

Cointelegraph's report of the same day adds that Ripple and LMAX had already announced a partnership in January 2026 to widen institutional use of RLUSD, so this is the next phase of an existing relationship rather than a new one.

How collateral mirroring works, in plain terms

Normally a fund that wants to post stablecoins as margin on a trading venue has to send those tokens to the venue. That creates two risks the fund would rather avoid: the transfer itself (wrong address, delays, operational errors) and the exposure to the venue if it fails while holding the tokens.

Under the mirroring model described in the release, the RLUSD stays in custody at Standard Chartered. The bank "mirrors" the value of the eligible collateral to LMAX Group, and LMAX recognises that value as margin for trading. The release says the set-up is expected to reduce "transfer-related operational risk" and help clients "optimise counterparty exposure while improving capital efficiency."

In practice, a hedge fund trading foreign exchange or crypto on LMAX could keep its dollars-on-chain at a regulated bank and still use them to back positions, instead of moving them onto an exchange balance sheet. This is the same logic as tri-party collateral in traditional markets, applied to a stablecoin.

The numbers behind RLUSD

DefiLlama's stablecoin dashboard, read at about 10:50 UTC on 12 October, put RLUSD in circulation at about $2.45 billion. Of that, about $1.30 billion sat on Ethereum and about $1.14 billion on the XRP Ledger. For scale, the same dashboard showed USDT at about $184.1 billion and USDC at about $73.0 billion, so RLUSD is roughly 1.3% the size of USDT by our arithmetic.

The custody service covers the XRPL portion. That matters for the XRP Ledger's role in Ripple's institutional pitch: Ripple's own boilerplate in the release describes RLUSD and XRP as the assets that "underpin" its payments, custody, prime brokerage and treasury products.

What the three companies said

Waqar Chaudry, Standard Chartered's global head of digital assets, financing and securities services, said institutional clients want to take part in digital asset markets "without compromising on how their assets are safeguarded or how risk is managed." Luke Dorney, head of custody for digital assets at LMAX Group, called RLUSD "an increasingly important component of institutional digital asset markets." Jack McDonald, Ripple's senior vice president for stablecoins, said customers want "the efficiency of a regulated stablecoin" without giving up the custody standards they already use.

LMAX describes itself as running FX and digital asset venues including LMAX Exchange (FCA-regulated MTF and MAS-regulated RMO), LMAX Global and LMAX Digital (GFSC-regulated venue and custodian), with clients in more than 100 countries. Ripple says it holds more than 85 licences.

Why this matters beyond Ripple

Three points stand out.

First, a global systemically important bank is now on the custody side of a dollar stablecoin that is not USDT or USDC. That gives RLUSD a route into institutional portfolios that do not want to hold tokens at a crypto-native custodian.

Second, the collateral plan addresses the problem that hurt traders most in past exchange failures: assets that sit on a venue's balance sheet. Keeping collateral at a bank and only mirroring its value to the venue is a structural answer, if it ships.

Third, the timing fits a week in which regulators are focused on stablecoins. The Financial Stability Board's report to the G20, which we covered earlier today in what the FSB stablecoin report means for USDT and USDC, warned that stablecoin frameworks remain untested in a crisis. Bank custody with segregated collateral is one of the safeguards those regulators have been asking for. In the EU, ESMA has separately told platforms to wind down non-compliant stablecoins (see our ESMA explainer).

What to watch next

• A start date and the first agreed LMAX products that accept RLUSD as collateral. The release says further details "will be announced as implementation progresses."
• Whether custody extends to RLUSD on Ethereum, which is the larger share of supply.
• Whether other venues adopt the same mirroring model with Standard Chartered.
• RLUSD's circulating supply on DefiLlama: a sustained rise on the XRPL side would be the clearest sign that the custody route is being used.
• Any follow-up from the XRP Ledger after the overflow bug it patched this weekend, covered in our XRPL bug piece.

What this means for you

If you are a retail trader, nothing changes in your account today: the custody is for eligible institutions and the collateral plan is not live. The useful lesson is the principle behind it. Whatever stablecoin you hold, the size of the balance you leave on any one trading venue is a risk decision. Keep only what you need for open positions on the exchange, move the rest to storage you control, and prefer venues that publish proof of reserves. If you trade derivatives on a major venue anyway, opening the account through a partner code means part of your trading fees comes back to you: on OKX the code is nexu888 (see the OKX profile for current terms), and fee rebates reduce costs without changing how your collateral is held.

Quick answers

Can I store RLUSD with Standard Chartered? Only if you are an eligible institutional client of its DIFC branch. The release does not describe any retail offer.

Is the LMAX collateral feature live? No. The three firms say they intend to enable it, subject to documentation, testing, regulation and approvals.

Which RLUSD is covered? The release names RLUSD issued on the XRP Ledger.

Who regulates the custody service? It is provided through Standard Chartered Bank's DIFC Branch, which the Dubai Financial Services Authority regulates.

Does this make RLUSD safer for me? It adds a bank custody option for institutions; it does not change RLUSD's reserves or the terms for retail holders.

What we could not verify

The release does not give eligibility criteria, fees, custody limits, the list of LMAX products, or a timetable. We could not read The Block's report on the same news, and Standard Chartered's own press page did not render the release when we checked, so we relied on the joint release published by LMAX Group and on Cointelegraph's report.

Supply figures come from DefiLlama at about 10:50 UTC on 12 October 2026 and will change; the share comparison is our arithmetic. The custody and collateral terms are as stated in the release on 12 October and may be revised as the firms finalise documentation.
