Customer securities accounts at Interactive Brokers LLC are not insured by FDIC. However, they are protected by the Securities Investor Protection Corporation ("SIPC") for a maximum coverage of $500,000 (with a cash sub-limit of $250,000) and under Interactive Brokers LLC's excess SIPC policy with certain underwriters at Lloyd's of London for up to an additional $30 million (with a cash sub-limit of $900,000) subject to an aggregate limit of $150 million. You can read more about the SIPC and Lloyd's of London policies on the Strength and Security page of our website.
For clients with over $250,000 in cash, we offer the Insured Bank Deposit Sweep Program which allows eligible IBKR clients to obtain up to $5,000,000 ($10,000,000 for joint accounts) of FDIC insurance in addition to the existing $250,000 SIPC coverage.
