LMAX Launches Kiosk, Turning Client Crypto Into Margin for FX and CFD Trading

LMAX Group launched “Kiosk”, a hosted, broker‑branded portal that lets brokers accept client crypto into LMAX Custody and use those balances as cross‑asset margin for spot FX, precious metals, CFDs, digital assets and perpetual futures. The product packages deposits, withdrawals, API credentialing, WalletConnect support and treasury controls to simplify onboarding and enable crypto to act as working capital inside brokers’ front ends. LMAX positions Kiosk amid growing competition from banks and prime brokers (JPMorgan, StoneX, Ripple Prime) and counts BlackBull Markets as an early adopter — notable because LMAX owns ~20.8% of BlackBull. Market impact: Kiosk could accelerate institutional use of Bitcoin/Ether as collateral, boost cross‑margin liquidity, and hasten integration of crypto balances into traditional trading workflows.
