How do forex brokers make money if they offer zero-commission trading?

Zero‑commission forex brokers earn revenue in ways other than a visible ticket fee. The most common method is to widen the spread, so you effectively pay more for every trade even though no separate commission appears on your statement. They may also gain from swap or overnight financing charges, currency conversion fees on deposits and withdrawals, or premium services and account types. Some market‑maker brokers can profit from client losses or by hedging flows internally, though reputable firms manage these risks carefully. A few also receive payments for order flow or internal routing arrangements in certain markets. For traders, the key is to compare total trading costs and conditions rather than focusing only on the “zero commission” label in advertising.
