LMAX Group, the London-based institutional trading venue, just rolled out a product that treats digital assets less like speculative playthings and more like what traditional finance already uses: collateral. The new platform, called Kiosk, lets banks, brokers, and asset managers deposit digital assets into LMAX Custody and then leverage those holdings as margin to trade across entirely different asset classes.
Your Bitcoin or Ether sits in custody, and instead of just sitting there, it backs your positions in spot foreign exchange, precious metals, contracts for difference, perpetual futures, and other digital assets.
What Kiosk actually does
The platform, which launched on May 12 in London, is a fully hosted portal designed to consolidate what has historically been a fragmented mess. Kiosk bundles deposits, withdrawals, and security management into a single interface.
The target audience here is LMAX Group’s existing network of over 600 institutional clients. They are banks and asset managers who already hold digital assets and want to put them to work without the operational headache of constantly reshuffling collateral across disconnected systems.
LMAX CEO David Mercer framed Kiosk as foundational infrastructure for modern capital markets, combining custody, connectivity, and collateral access into a single layer.
Where this fits in the competitive landscape
LMAX occupies a distinct lane from crypto-native custodians. The group has operated regulated FX and metals venues for traditional institutions long before it added crypto. Its digital asset exchange, LMAX Digital, launched specifically to serve banks and brokers who wanted institutional-grade execution in crypto. Kiosk extends that logic by saying: now your crypto holdings can support your activity across all of our venues, not just the crypto one.
Most crypto exchanges let you use Bitcoin as collateral for crypto trades. Fewer platforms let you use Bitcoin as collateral for a euro-dollar FX position or a gold CFD. LMAX is positioning Kiosk at exactly that intersection.
