Institutions prohibited from depositing margin collateral directly with a broker/dealer can open an IBKR Custody Account to trade stocks, options and futures.

Assets (e.g., long stock, retail and government money-market funds, and Treasuries only) that are held at a pledged account at the Custodial bank are reflected in the customers IBKR trading account and used to margin trades.
