Prime Broker Services

Prime Broker Services


Our prime brokerage services are built on 39 years of providing innovative technology solutions to our clients.
Since 1977 Interactive Brokers1 has focused on applying technology to every part of the trading and settlement process. Through our highly automated technology, we execute trades for our clients on over 100 exchange and market centers in 24 countries, and group-wide we clear and settle over 1,000,000 trades per day2. Our global reach, substantial equity capital and low-risk business model give us a unique competitive advantage in today's rapidly changing markets.


Strong Balance Sheet

Our capital has grown organically from profits over the years. We are part of IB Group, which has over US $5.8 billion in equity capital2 and no long-term debt. The group is still approximately 84% owned by the original owners who closely manage the business.

Large Relative Equity Capital

Interactive Brokers LLC has over US $3 billion in regulatory net capital, which is $2.8 billion in excess of regulatory requirements. The Firm uses proprietary software to automate broker-dealer functions and integrate its software with exchanges and trading venues into one automatically functioning, computerized platform. The orders that our clients enter into the Trader WorkStation (TWS) or other order management systems are electronically routed to the markets using our proprietary order routing technology.

IB also uses a real-time risk management system that works behind the scenes to manage risk and enforce credit-related regulations. We require all orders submitted for accounts held at IB to be credit checked prior to accepting the order for routing to the market. The system ensures that trades will be supported by current equity in the account and also automatically liquidates under-margined positions without making margin calls. This policy protects the firm's capital and the rest of the firm's clients as well as limiting the losses in client accounts.

Low Risk Business Model

Interactive Brokers LLC is an agency broker for its clients. It does not maintain a proprietary trading desk or sales trading desk and does not trade for its own account.


Client Fund Protection

As a regulated broker, Interactive Brokers is subject to SEC and CFTC regulations regarding investment of client funds. Permissible investment vehicles include bank deposits and a variety of top-rated government securities and related instruments. Our effective investment policy is more stringent than this, reflecting our risk-averse philosophy. We invest client funds only in government securities, repos of government securities and cash deposits in bank accounts at the largest banks. Our investment policy is conservative. Our strict policy when investing client money minimizes your exposure and ours in uncertain credit environments.

Consistent Performance

Financial professionals who find the large prime brokers too expensive to meet their needs come to us from around the world in increasing numbers. Our ongoing focus on using technology to connect to the world's markets and automate all aspects of the trading and settlement process, combined with our low-risk business model and risk-averse philosophy results in continued growth of our clients' equity.
