What is Forex Spread?
Forex spread is the difference between the buying price (Ask) and the selling price (Bid) of a currency pair on the market.
  • Bid price: the price at which you can sell the base currency.
  • Ask price: the price at which you can buy the base currency.
  • Spread: is Ask – Bid, expressed in pips.
For example: GBP/USD pair is showing the price 1.1996/1.1993.
  • Ask = 1.1996
  • Bid = 1.1993
  • Spread = 1.1996 – 1.1993 = 3 pips
This means that as soon as you open a trade, you have incurred a cost of 3 pips. Forex spread is a part of the profit that the broker earns when providing liquidity to traders.

Types of Forex Spreads

In the market, there are two main types of spreads:

Fixed Spread

  • Always remains the same, regardless of strong or weak market fluctuations.
  • Usually applied by Market Maker trading floors.
  • Advantages: easy to predict costs, suitable for beginners.
  • Disadvantages: usually higher than floating spreads.

Variable Spread

  • Changes according to liquidity and market fluctuations.
  • Commonly applied at ECN/STP floors.
  • Advantages: usually low when the market is stable, helping to reduce costs.
  • Disadvantages: can widen greatly during strong news or unusual volatility.
For example, during the NFP (Nonfarm Payrolls) announcement, the EUR/USD spread can increase from 1 pip to 10 pips or more.

Factors affecting Forex Spread

There are many factors that cause forex spreads to change, the most common of which include:

Liquidity

  • Major currency pairs (EUR/USD, GBP/USD, USD/JPY) have high trading volume → low spreads.
  • Exotic pairs are less traded → high spreads.

Market volatility

  • Quiet market → narrow spreads.
  • When there is big news or strong volatility → spreads widen.

  • London – New York session overlap has low spreads due to high liquidity.
  • Sydney session markets often have higher spreads due to lower trading volumes.

Broker Policy

  • Standard accounts often have higher spreads than professional accounts.
  • Some brokers, instead of charging low spreads, apply additional commission fees.

The Impact of Forex Spreads on Trading

Understanding forex spreads is important because it directly affects the trading costs and strategies of traders.
  1. Order entry costs: The higher the spread, the higher the costs. For scalpers (short-term traders), even a few pips increase in spread can significantly affect profits.
  2. Order execution ability: During news events, widening spreads can cause stop-loss or take-profit orders to not be executed as expected.
  3. Currency pair selection: Traders often prioritize pairs with low spreads to optimize costs, especially when trading in the short term.
  4. Trading psychology: Unexpectedly widening spreads can make traders lose confidence and affect decisions.

How to calculate Forex Spread

Spread is calculated in pips – the smallest fluctuation of a currency pair.
Formula: Spread (pip) = Ask Price – Bid Price
For example: If the EUR/USD pair displays 1.1012/1.1010:
  • Ask = 1.1012
  • Bid = 1.1010
  • Spread = 0.0002 → corresponding to 2 pips.
Spreads can change continuously according to market fluctuations, so monitoring forex spreads is necessary to estimate transaction costs before placing an order.

Some examples of average spreads (may change over time):
  • EUR/USD: 5 – 2 pips (very low, due to the highest liquidity).
  • GBP/USD: 1 – 3 pips (higher volatility, spreads are usually wider).
  • USD/JPY: 1 – 2 pips.
  • Exotic pairs (USD/TRY, USD/ZAR): can be up to 20 – 50 pips.
This explains why most traders focus on major currency pairs – which are both highly liquid and have low forex spreads.

Managing Forex Spreads in Trading

Traders cannot eliminate spreads, but they can manage and minimize their impact:
  1. Choose the time to trade: Trade during peak hours (London – New York overlap) to take advantage of tight spreads.
  2. Avoid strong news: Spreads can widen abnormally when economic data is released.
  3. Choose the right currency pair: Prioritize major currency pairs over exotic pairs.
  4. Compare accounts and brokers: Some ECN accounts have very low spreads, even though they have to pay an additional commission.
  5. Monitor market volatility: Always pay attention to the displayed spread before placing an order to calculate the risk.
