Introduction: The Business Behind Forex Trading
Ever wondered how forex brokers make money if they don’t always charge commissions? The answer lies in the spread. It may look like just a tiny difference between the buy and sell price, but for brokers, spreads are the bread and butter of their business. Multiply that small gap across thousands of traders and millions of trades, and you’ll see why spreads are such a powerful profit engine.
What Is a Spread in Forex?
The spread is the gap between the bid price (what buyers are willing to pay) and the ask price (what sellers want).
Example:
- EUR/USD bid = 1.1000
- EUR/USD ask = 1.1002
- Spread = 2 pips
That small 2-pip difference is your cost and the broker’s revenue.
The Role of Spreads in Broker Profits
When you open a trade, you start slightly in the negative because of the spread. That loss isn’t random—it goes to the broker. This is how brokers profit without charging traditional fees.
Types of Brokers and How They Use Spreads
Market Makers
- Set their own bid and ask prices.
- Profit directly from spreads since they control the quote.
- Sometimes take the opposite side of your trade, which adds to their earnings.
ECN (Electronic Communication Network) Brokers
- Provide access to interbank liquidity.
- Offer raw spreads (sometimes as low as 0.0 pips).
- Make money by charging commissions instead of adding large markups.
STP (Straight Through Processing) Brokers
- Route your trades to liquidity providers.
- Add a small markup to the spread before passing it on.
- Earn by widening the market spread slightly.
Why Spreads Differ Between Brokers
- Liquidity: More liquid pairs (like EUR/USD) have tighter spreads than exotic pairs (like USD/TRY).
- Broker model: ECN = tight spreads + commission; Market Maker = wider spreads, no commission.
- Market volatility: Spreads widen during news events and uncertain conditions.
- Trading hours: Spreads are tighter during London/New York overlap and wider during off-hours.
Example of Broker Profit from Spreads
Let’s say you trade 1 standard lot of EUR/USD (100,000 units):
- Spread = 2 pips
- Value per pip = $10
- Cost to trader = $20
That $20 is the broker’s revenue from your trade. Now imagine 10,000 traders each making similar trades—that’s $200,000 in spread revenue in a single day.
Do Brokers Always Keep the Spread?
- Market makers: Yes, spreads are their main profit source.
- ECN/STP brokers: They pass spreads from liquidity providers but may add a markup or charge commissions.
Why Brokers Want You to Keep Trading
Since brokers earn from spreads, the more you trade, the more they make. That’s why they often:
- Offer bonuses or promotions to encourage frequent trading.
- Provide leverage, so you open bigger positions (higher spread costs).
- Give access to lots of currency pairs to maximize opportunities.
Spreads vs Commissions: Two Revenue Models
- Spread-only model: Brokers widen the spread slightly and profit directly from it.
- Commission + raw spread model: Brokers pass on tight spreads and charge a commission per lot.
In the end, both models ensure brokers earn every time you trade.
How to Protect Yourself from Excessive Spread Costs
- Choose brokers with tight spreads (especially for scalping).
- Avoid trading during big news events if you’re not experienced.
- Trade liquid pairs like EUR/USD or GBP/USD for the lowest spreads.
- Compare total costs (spread + commission) across brokers.
Conclusion
Spreads may look tiny, but they’re the lifeblood of a broker’s business. Whether you’re paying a 1-pip or 3-pip spread, every trade you make contributes to your broker’s revenue. That doesn’t mean spreads are bad—they’re simply the cost of doing business in forex. The key is to choose a broker with fair spreads, transparent pricing, and a model that fits your trading style.
