Forex Spreads Explained: How Currency Pairs Cost You
In forex trading, the spread is the primary cost you pay. Understand how forex spreads are calculated, what makes them widen, and how to choose a broker with competitive spreads.
Key Takeaways
- ✓Forex spreads are measured in pips — the smallest price movement in a currency pair — and represent the main cost of currency trading.
- ✓Major pairs like EUR/USD typically have the tightest spreads (0.1-1.5 pips), while exotic pairs can have spreads of 5 pips or more.
- ✓Fixed-spread brokers and variable-spread brokers each have advantages and disadvantages depending on your trading style.
- ✓A spread that is 0.5 pips wider can cost a day trader thousands of dollars extra per month.
In forex trading, the spread is not just one of many costs — it is typically the primary cost. Unlike stock trading where commissions were historically the main fee, forex brokers have traditionally profited from the spread between the bid and ask prices on currency pairs. Understanding how these spreads work is essential for any aspiring currency trader.
What Is a Pip?
A pip (Percentage in Point) is the smallest standard price movement in a forex quote. For most currency pairs, a pip equals 0.0001 (the fourth decimal place). For example, if EUR/USD moves from 1.0850 to 1.0851, that is a one-pip movement. For pairs involving the Japanese yen, a pip equals 0.01 (the second decimal place) because the yen is quoted to fewer decimal places.
The monetary value of one pip depends on your position size. For a standard lot (100,000 units), one pip in EUR/USD is worth approximately $10. For a mini lot (10,000 units), one pip is approximately $1. For a micro lot (1,000 units), one pip is approximately $0.10.
Forex Spread Types
| Spread Type | How It Works | Pros | Cons |
|---|---|---|---|
| Fixed spread | Remains constant regardless of market conditions | Predictable costs, easy to calculate | May be wider than variable spreads during calm markets |
| Variable (floating) spread | Changes based on market liquidity and volatility | Often tighter during normal conditions | Can widen dramatically during news events |
| Commission + raw spread | Raw interbank spread plus a fixed commission | Most transparent pricing | Requires calculation of total cost |
Typical Spreads by Currency Pair
Spread costs vary significantly across currency pairs. Here are typical ranges for major, minor, and exotic pairs at competitive brokers:
| Pair Category | Example | Typical Spread | Spread Cost per Standard Lot |
|---|---|---|---|
| Major pair | EUR/USD | 0.1 - 1.5 pips | $1 - $15 |
| Major pair | GBP/USD | 0.3 - 2.0 pips | $3 - $20 |
| Minor pair | EUR/GBP | 1.0 - 3.0 pips | $10 - $30 |
| Minor pair | AUD/NZD | 1.5 - 4.0 pips | $15 - $40 |
| Exotic pair | USD/TRY | 5.0 - 30+ pips | $50 - $300+ |
| Exotic pair | EUR/ZAR | 10.0 - 50+ pips | $100 - $500+ |
What Causes Spreads to Widen?
Forex spreads are not static — they fluctuate based on market conditions. Understanding when spreads widen helps you plan your trading to avoid unnecessary costs:
- •Major economic announcements — Non-Farm Payrolls, CPI data, and central bank rate decisions typically cause spreads to widen significantly in the minutes before and after the release.
- •Market open and close — spreads are generally wider during the overlap and transitions between major trading sessions.
- •Low-liquidity periods — holidays, weekends, and late Asian session hours see reduced liquidity and wider spreads.
- •Geopolitical events — unexpected political developments or market shocks cause immediate spread widening.
- •Flash crashes — extreme market events can cause spreads to blow out to hundreds of pips momentarily.
How to Evaluate Forex Broker Spreads
When comparing forex brokers, do not rely solely on the advertised average spread. Instead, request or look for average spread data during specific market conditions — particularly during the London-New York overlap (the most liquid period) and during major news events. A broker that advertises 0.8 pips on EUR/USD but regularly widens to 5 pips during news may cost more than a broker advertising 1.2 pips that maintains reasonable spreads during volatility.
