Interactive Brokers is a broker for professionals: low commissions, access to dozens of exchanges, minimal marketing.
Customers are active traders, small funds and affluent private investors worldwide. The company competes not on beginner-friendliness but on execution price and breadth of access: one account trades equities, bonds, futures and currencies across dozens of markets.
Income combines commissions with, more importantly, interest: client balances and margin lending supply a substantial part of profit when rates are high. Costs are low thanks to automation — the company has historically run a small staff against an enormous transaction volume. The dividend is small. When rates fall that income shrinks automatically and trading volume returns to the fore.
